In that time, many clinical MMD studies have been performed from several different points of view, such as epidemiology, pathophysiology, surgical procedures, and prognosis. In addition, rapid developments in MMD genetic analysis have occurred. In light of all this activity, clinicians must continually update their knowledge of MMD in order to improve the prognosis of MMD patients. In this review article, we summarize the clinical MMD studies and introduce cutting-edge findings regarding MMD. en-copyright= kn-copyright= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=clinical research kn-keyword=clinical research en-keyword=moyamoya disease kn-keyword=moyamoya disease END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=6 article-no= start-page=493 end-page=496 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgery in the Standing Position by a Surgeon with Achilles Tendon Rupture en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unexpected injuries can have a profound effect on a surgeon?s performance and thus on patients and surgical departments. Here we describe a technique for performing surgery in the standing position, as done by a surgeon with an Achilles tendon rupture. During his prescribed 45-day non-weight-bearing period for the left ankle after surgery for an Achilles tendon rupture, the surgeon was able to participate in 15 surgeries as an operator or assistant, due to his use of a combination of injured-leg genuflection on a stool and a ?Surgical Body Support? device. Similarly injured surgeons may benefit from such support. en-copyright= kn-copyright= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuwaharaKen en-aut-sei=Kuwahara en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ToyoshimaAtsuhiko en-aut-sei=Toyoshima en-aut-mei=Atsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorimotoJun en-aut-sei=Morimoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ManabeHiroaki en-aut-sei=Manabe en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiYasuyuki en-aut-sei=Miyoshi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KusumegiAkira en-aut-sei=Kusumegi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiYuichiro en-aut-sei=Takahashi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ItoKiyoshi en-aut-sei=Ito en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Spinal Surgery, Shinkomonji Hospital kn-affil= affil-num=11 en-affil=Department of Neurosurgery, Shinshu University kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Achilles tendon rupture kn-keyword=Achilles tendon rupture en-keyword=electromyogram kn-keyword=electromyogram en-keyword=genuflection kn-keyword=genuflection en-keyword=injured leg kn-keyword=injured leg en-keyword=standing position kn-keyword=standing position END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=2 article-no= start-page=179 end-page=180 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intracranial Pressure Monitoring for Pediatric Acute Encephalopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Newly published clinical practice guidelines recommend intracranial pressure (ICP) monitoring in critical care for the management of pediatric acute encephalopathy (pAE), but the utility of ICP monitoring for pAE has been poorly studied. We recently performed direct ICP monitoring for two patients. We observed that although the direct ICP monitoring had clinical benefits with less body weight gain and no vasopressor use in both cases, this monitoring technique is still invasive. Future studies should determine the utility of non-invasive ICP monitoring systems in pAE to further improve the quality of intensive-care management. en-copyright= kn-copyright= en-aut-name=NosakaNobuyuki en-aut-sei=Nosaka en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KnaupEmily en-aut-sei=Knaup en-aut-mei=Emily kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YabuuchiToshihiko en-aut-sei=Yabuuchi en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikkawaTomonobu en-aut-sei=Kikkawa en-aut-mei=Tomonobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiYosuke en-aut-sei=Fujii en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YashiroMasato en-aut-sei=Yashiro en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UgawaToyomu en-aut-sei=Ugawa en-aut-mei=Toyomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Advanced Emergency and Critical Care Medical Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Advanced Emergency and Critical Care Medical Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Advanced Emergency and Critical Care Medical Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=10 en-affil=Advanced Emergency and Critical Care Center of Okayama University Hospital kn-affil= affil-num=11 en-affil=Advanced Emergency and Critical Care Medical Center, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= en-keyword=cerebral perfusion kn-keyword=cerebral perfusion en-keyword=encephalopathy kn-keyword=encephalopathy en-keyword=child kn-keyword=child en-keyword=intracranial pressure kn-keyword=intracranial pressure en-keyword=neurological intensive care kn-keyword=neurological intensive care END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=191 end-page=200 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201706 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of High-frequency Electrical Brain Activity en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Electroencephalogram (EEG) data include broadband electrical brain activity ranging from infra-slow bands (< 0.1 Hz) to traditional frequency bands (e.g., the approx. 10 Hz alpha rhythm) to high-frequency bands of up to 500 Hz. High-frequency oscillations (HFOs) including ripple and fast ripple oscillations (80-200 Hz and>200 / 250 Hz, respectively) are particularly of note due to their very close relationship to epileptogenicity, with the possibility that they could function as a surrogate biomarker of epileptogenicity. In contrast, physiological high-frequency activity plays an important role in higher brain functions, and the differentiation between pathological / epileptic and physiological HFOs is a critical issue, especially in epilepsy surgery. HFOs were initially recorded with intracranial electrodes in patients with intractable epilepsy as part of a long-term invasive seizure monitoring study. However, fast oscillations (FOs) in the ripple and gamma bands (40-80 Hz) are now noninvasively detected by scalp EEG and magnetoencephalography, and thus the scope of studies on HFOs /FOs is rapidly expanding. en-copyright= kn-copyright= en-aut-name=KobayashiKatsuhiro en-aut-sei=Kobayashi en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AgariTakashi en-aut-sei=Agari en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShibataTakashi en-aut-sei=Shibata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HanaokaYoshiyuki en-aut-sei=Hanaoka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkiyamaMari en-aut-sei=Akiyama en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=EndohFumika en-aut-sei=Endoh en-aut-mei=Fumika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkaMakio en-aut-sei=Oka en-aut-mei=Makio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Epilepsy Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Epilepsy Center, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=fast oscillations, epilepsy kn-keyword=fast oscillations, epilepsy en-keyword=electroencephalogram kn-keyword=electroencephalogram en-keyword=time-frequency analysis kn-keyword=time-frequency analysis END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=4 article-no= start-page=263 end-page=268 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201708 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mesenchymal Stem Cell Therapy for Ischemic Stroke en-subtitle= kn-subtitle= en-abstract= kn-abstract=　To date, many animal studies have indicated the neuroprotective effects of mesenchymal stem cell (MSC) transplantation in ischemic stroke. Several clinical studies have also revealed the safety, feasibility, and neuroprotective effects in ischemic stroke patients. In this review, we present the main approaches of MSC transplantation in ischemic stroke, the mechanisms of MSC therapy, and the current clinical studies on MSC transplantation in ischemic stroke patients. We also explore the safety of MSC transplantation and conclude that MSC therapy will play an important role in the future treatment of ischemic stroke. The optimal timing, approach, and cell dose in the transplantation are important issues for successful clinical application. en-copyright= kn-copyright= en-aut-name=ToyoshimaAtsuhiko en-aut-sei=Toyoshima en-aut-mei=Atsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=mesenchymal stem cell kn-keyword=mesenchymal stem cell en-keyword= ischemic stroke kn-keyword= ischemic stroke en-keyword= cell transplantation kn-keyword= cell transplantation en-keyword=clinical trial kn-keyword=clinical trial END start-ver=1.4 cd-journal=joma no-vol=159 cd-vols= no-issue=7 article-no= start-page=1329 end-page=1333 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=De novo vertebral artery dissecting aneurysm after internal trapping of the contralateral vertebral artery en-subtitle= kn-subtitle= en-abstract= kn-abstract= We present the case of a de novo vertebral artery dissecting aneurysm (VADA) after endovascular trapping of a ruptured VADA on the contralateral side. The first ruptured VADA involved the posterior inferior cerebellar artery, which was successfully treated by endovascular internal trapping using a stent. A follow-up study at 3 months revealed a de novo VADA on the contralateral side. The second VADA was successfully embolized using coils while normal arterial flow in the vertebral artery was preserved using a stent. Increased hemodynamic stress may cause the development of a de novo VADA on the contralateral side. en-copyright= kn-copyright= en-aut-name=KidaniNaoya en-aut-sei=Kidani en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishihiroShingo en-aut-sei=Nishihiro en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=De novo aneurysm kn-keyword=De novo aneurysm en-keyword=Hemodynamic stress kn-keyword=Hemodynamic stress en-keyword=Stent-assisted coil embolization kn-keyword=Stent-assisted coil embolization en-keyword=Vertebral artery dissecting aneurysm kn-keyword=Vertebral artery dissecting aneurysm END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=1 article-no= start-page=85 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Radiation-Induced Osteosarcoma with RB1 Gene Alteration Treated by Skull Base Surgery and Craniofacial Reconstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 35-year-old female presented with headache, photophobia and developed sudden loss of vision after having undergone right-side ophthalmectomy and radiochemotherapy for retinoblastoma in infancy. A neoplastic lesion was found in the left middle cranial fossa and was surgically removed. The diagnosis was radiation-induced osteosarcoma with RB1 gene alteration. Although she received chemotherapy for the residual tumor, it progressed 17 months later. Maximal surgical resection with craniofacial reconstruction was required. We utilized two three-dimensional models for surgical planning. She was discharged without neurological deficits other than loss of light perception subsequent to left ophthalmectomy. In cases where retinoblastoma is treated with radiotherapy, long-term follow-up is necessary to monitor for radiation-induced tumor development. en-copyright= kn-copyright= en-aut-name=MatsudaYuki

intratumoral inoculation of mesenchymal stem cells (MSCs) expressing cytosine deaminase gene with 5-fluorocytosine (5-FC) administration. For in vitro and in vivo experiments, MSCs were transfected with adenovirus carrying either enhanced green fluorescent protein gene (AdexCAEGFP) or cytosine deaminase gene (AdexCACD), to establish MSC-expressing EGFP (MSC-EGFP) or CD (MSC-CD). Co-culture of 9L glioma cells with MSC-CD in a medium containing 5-FC resulted in a remarkable reduction in 9L cell viability. The migratory ability of MSC-EGFP toward 9L cells was demonstrated by double-chamber assay. For the in vivo study, rats harboring 9L brain tumors were inoculated with MSC-EGFP or MSC-CD. Immunohistochemistry of rat brain tumors inoculated with MSC-EGFP showed intratumoral distribution of MSC-EGFP. Survival analysis of rats bearing 9L gliomas treated with intratumoral MSC-CD and intraperitoneal 5-FC resulted in significant prolongation of survival compared with control animals. In conclusion, molecular therapy combining suicide gene therapy and MSCs as a targeting vehicle represents a potential new therapeutic approach for malignant glioma, both with respect to the antitumor potential of this system and its neuroprotective effect on normal brain tissue. en-copyright= kn-copyright= en-aut-name=KosakaH en-aut-sei=Kosaka en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaT en-aut-sei=Ichikawa en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiK en-aut-sei=Kurozumi en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KambaraH en-aut-sei=Kambara en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueS en-aut-sei=Inoue en-aut-mei=S kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaruoT en-aut-sei=Maruo en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraK en-aut-sei=Nakamura en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamadaH en-aut-sei=Hamada en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateI en-aut-sei=Date en-aut-mei=I kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil= kn-affil= affil-num=7 en-affil= kn-affil=Hokkaido Univ, Grad Sch Life Sci, Fac Adv Life Sci, Innate Immun Lab affil-num=8 en-affil= kn-affil=Tokyo Univ Pharm & Life Sci, Dept Life Sci affil-num=9 en-affil= kn-affil= en-keyword=glioma kn-keyword=glioma en-keyword=mesenchymal stem cell kn-keyword=mesenchymal stem cell en-keyword=suicide gene kn-keyword=suicide gene en-keyword=bystander effect kn-keyword=bystander effect END start-ver=1.4 cd-journal=joma no-vol=161 cd-vols= no-issue=8 article-no= start-page=1675 end-page=1682 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A comparison of the prevalence and risk factors of complications in intracranial tumor embolization between the Japanese Registry of NeuroEndovascular Therapy 2 (JR-NET2) and JR-NET3 en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND:
The Japanese Registry of NeuroEndovascular Therapy 2 (JR-NET2) and 3 (JR-NET3) were nationwide surveys that evaluated clinical outcomes after neuroendovascular therapy in Japan. The aim of this study was to compare the prevalence and risk factors of complications of intracranial tumor embolization between JR-NET2 and JR-NET3.
METHODS:
A total of 1018 and 1545 consecutive patients with intracranial tumors treated with embolization were enrolled in JR-NET2 and JR-NET3, respectively. The prevalence of complications in intracranial tumor embolization and related risk factors were compared between JR-NET2 and JR-NET3.
RESULTS:
The prevalence of complications in JR-NET3 (3.69%) was significantly higher than that in JR-NET2 (1.48%) (p?=?0.002). The multivariate analysis in JR-NET2 showed that embolization for tumors other than meningioma was the only significant risk factor for complication (odds ratio [OR], 3.88; 95% confidence interval [CI], 1.13-12.10; p?=?0.032), and that in JR-NET3 revealed that embolization for feeders other than external carotid artery (ECA) (OR, 3.56; 95% CI, 2.03-6.25; p? CONCLUSIONS:
Embolization for feeders other than ECA and use of liquid materials could increase the complication rate in intracranial tumor embolization. en-copyright= kn-copyright= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraiSatoshi en-aut-sei=Murai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KidaniNaoya en-aut-sei=Kidani en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishihiroShingo en-aut-sei=Nishihiro en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatowTetsu en-aut-sei=Satow en-aut-mei=Tetsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IiharaKoji en-aut-sei=Iihara en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakaiNobuyuki en-aut-sei=Sakai en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=JR-NET2 and JR-NET3 study groups. en-aut-sei=JR-NET2 and JR-NET3 study groups. en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of NeurosurgeryNational Cerebral and Cardiovascular Center kn-affil= affil-num=10 en-affil=Department of Neurosurgery Graduated School of Medical SciencesKyusyu University kn-affil= affil-num=11 en-affil=Department of NeurosurgeryKobe City Medical Center General Hospital kn-affil= affil-num=12 en-affil= kn-affil= en-keyword=Complication kn-keyword=Complication en-keyword=Embolization kn-keyword=Embolization en-keyword=Intracranial tumor kn-keyword=Intracranial tumor en-keyword=Risk factors kn-keyword=Risk factors END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue= article-no= start-page=100489 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cavernous malformation of the optic chiasm with continuous hemorrhage in a pregnant woman: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Cavernous malformation of the anterior visual pathway is rare, especially in pregnant woman. Planning a treatment strategy with cross-disciplinary specialists is important.
Case description A 27-year-old pregnant woman presented with acute hemorrhage around the right optic nerve and chiasm, manifesting as poor vision in both eyes. Examination revealed right-eye deteriorated acuity and bilateral temporal hemianopsia. Computed tomography showed an oval high-density mass in the suprasellar region. Gradient echo-based T2-weighted magnetic resonance imaging showed the lesion to be hypointense (possibly a hematoma) and mainly in the optic chiasm. Fluid attenuated inversion recovery imaging showed a bilateral optic tract surrounding the lesion, which enlarged over 1?week, increasing the loss of visual function. Five days after admission, she delivered a healthy >2500-g baby by cesarean section (CS). Right frontotemporal craniotomy was performed 7?days after CS. Incision of the right optic nerve's lateral surface revealed clotted blood with abnormal vascular construction from the right side of the chiasm. We removed the hematoma and vascular lesion. Visual evoked potentials were detected only after optic chiasm decompression. Histological evaluation revealed a hematoma-like lesion with capsules and hemosiderin deposition, suggesting cavernous malformation. Her postoperative recovery was uneventful, with right visual acuity returning to normal, and her visual field not deteriorating any more.
Conclusion Devising a treatment strategy with the obstetrician was important in this case to manage the hematoma and cavernous malformation safely. en-copyright= kn-copyright= en-aut-name=TomitaYusuke en-aut-sei=Tomita en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name=0000-0002-6942-9919 kn-aut-sei=0000-0002-6942-9919 kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImotoRyoji en-aut-sei=Imoto en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitsuiTakashi en-aut-sei=Mitsui en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MishimaSakurako en-aut-sei=Mishima en-aut-mei=Sakurako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InagakiKenichi en-aut-sei=Inagaki en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Endocrine Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Optic nerve kn-keyword=Optic nerve en-keyword=Cavernous hemangioma kn-keyword=Cavernous hemangioma en-keyword=Pregnant kn-keyword=Pregnant en-keyword=Visual evoked potential kn-keyword=Visual evoked potential END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=21 article-no= start-page=E5402 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Animal Models for Parkinson's Disease Research: Trends in the 2000s en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson's disease (PD) is a chronic and progressive movement disorder and the second most common neurodegenerative disease. Although many studies have been conducted, there is an unmet clinical need to develop new treatments because, currently, only symptomatic therapies are available. To achieve this goal, clarification of the pathology is required. Attempts have been made to emulate human PD and various animal models have been developed over the decades. Neurotoxin models have been commonly used for PD research. Recently, advances in transgenic technology have enabled the development of genetic models that help to identify new approaches in PD research. However, PD animal model trends have not been investigated. Revealing the trends for PD research will be valuable for increasing our understanding of the positive and negative aspects of each model. In this article, we clarified the trends for animal models that were used to research PD in the 2000s, and we discussed each model based on these trends. en-copyright= kn-copyright= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil= Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil= Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil= Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=animal model kn-keyword=animal model en-keyword=alpha-synuclein kn-keyword=alpha-synuclein en-keyword=DJ-1 kn-keyword=DJ-1 en-keyword=neurotoxin kn-keyword=neurotoxin en-keyword=Parkin kn-keyword=Parkin en-keyword=Parkinson's disease kn-keyword=Parkinson's disease en-keyword=pesticide kn-keyword=pesticide en-keyword=PINK1 kn-keyword=PINK1 en-keyword=1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine kn-keyword=1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine en-keyword=6-hydroxydopamine kn-keyword=6-hydroxydopamine END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=42 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Annexin A2-STAT3-Oncostatin M receptor axis drives phenotypic and mesenchymal changes in glioblastoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioblastoma (GBM) is characterized by extensive tumor cell invasion, angiogenesis, and proliferation. We previously established subclones of GBM cells with distinct invasive phenotypes and identified annexin A2 (ANXA2) as an activator of angiogenesis and perivascular invasion. Here, we further explored the role of ANXA2 in regulating phenotypic transition in GBM. We identified oncostatin M receptor (OSMR) as a key ANXA2 target gene in GBM utilizing microarray analysis and hierarchical clustering analysis of the Ivy Glioblastoma Atlas Project and The Cancer Genome Atlas datasets. Overexpression of ANXA2 in GBM cells increased the expression of OSMR and phosphorylated signal transducer and activator of transcription 3 (STAT3) and enhanced cell invasion, angiogenesis, proliferation, and mesenchymal transition. Silencing of OSMR reversed the ANXA2-induced phenotype, and STAT3 knockdown reduced OSMR protein expression. Exposure of GBM cells to hypoxic conditions activated the ANXA2-STAT3-OSMR signaling axis. Mice bearing ANXA2-overexpressing GBM exhibited shorter survival times compared with control tumor-bearing mice, whereas OSMR knockdown increased the survival time and diminished ANXA2-mediated tumor invasion, angiogenesis, and growth. Further, we uncovered a significant relationship between ANXA2 and OSMR expression in clinical GBM specimens, and demonstrated their correlation with tumor histopathology and patient prognosis. Our results indicate that the ANXA2-STAT3-OSMR axis regulates malignant phenotypic changes and mesenchymal transition in GBM, suggesting that this axis is a promising therapeutic target to treat GBM aggressiveness. en-copyright= kn-copyright= en-aut-name=MatsumotoYuji en-aut-sei=Matsumoto en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomitaYusuke en-aut-sei=Tomita en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HattoriYasuhiko en-aut-sei=Hattori en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UnedaAtsuhito en-aut-sei=Uneda en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsuboiNobushige en-aut-sei=Tsuboi en-aut-mei=Nobushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KanedaKeisuke en-aut-sei=Kaneda en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MakinoKeigo en-aut-sei=Makino en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=ANXA2 kn-keyword=ANXA2 en-keyword=OSMR kn-keyword=OSMR en-keyword=Invasion kn-keyword=Invasion en-keyword=Mesenchymal transition kn-keyword=Mesenchymal transition en-keyword=Glioblastoma kn-keyword=Glioblastoma END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=11 article-no= start-page=4137 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cerebellar Blood Flow and Gene Expression in Crossed Cerebellar Diaschisis after Transient Middle Cerebral Artery Occlusion in Rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Crossed cerebellar diaschisis (CCD) is a state of hypoperfusion and hypometabolism in the contralesional cerebellar hemisphere caused by a supratentorial lesion, but its pathophysiology is not fully understood. We evaluated chronological changes in cerebellar blood flow (CbBF) and gene expressions in the cerebellum using a rat model of transient middle cerebral artery occlusion (MCAO). CbBF was analyzed at two and seven days after MCAO using single photon emission computed tomography (SPECT). DNA microarray analysis and western blotting of the cerebellar cortex were performed and apoptotic cells in the cerebellar cortex were stained. CbBF in the contralesional hemisphere was significantly decreased and this lateral imbalance recovered over one week. Gene set enrichment analysis revealed that a gene set for "oxidative phosphorylation" was significantly upregulated while fourteen other gene sets including "apoptosis", "hypoxia" and "reactive oxygen species" showed a tendency toward upregulation in the contralesional cerebellum. MCAO upregulated the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in the contralesional cerebellar cortex. The number of apoptotic cells increased in the molecular layer of the contralesional cerebellum. Focal cerebral ischemia in our rat MCAO model caused CCD along with enhanced expression of genes related to oxidative stress and apoptosis. en-copyright= kn-copyright= en-aut-name=KidaniNaoya en-aut-sei=Kidani en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishihiroShingo en-aut-sei=Nishihiro en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MuraiSatoshi en-aut-sei=Murai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=apoptosis kn-keyword=apoptosis en-keyword=cerebral blood flow kn-keyword=cerebral blood flow en-keyword=crossed cerebellar diaschisis kn-keyword=crossed cerebellar diaschisis en-keyword=ischemic stroke kn-keyword=ischemic stroke en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=164 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Continuous Cervical Spinal Cord Stimulation Exerts Neuroprotective Effects in Experimental Parkinson's Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Spinal cord stimulation (SCS) exerts neuroprotective effects in animal models of Parkinson’s disease (PD). Conventional stimulation techniques entail limited stimulation time and restricted movement of animals, warranting the need for optimizing the SCS regimen to address the progressive nature of the disease and to improve its clinical translation to PD patients.
Objective: Recognizing the limitations of conventional stimulation, we now investigated the effects of continuous SCS in freely moving parkinsonian rats.
Methods: We developed a small device that could deliver continuous SCS. At the start of the experiment, thirty female Sprague-Dawley rats received the dopamine (DA)-depleting neurotoxin, 6-hydroxydopamine, into the right striatum. The SCS device was fixed below the shoulder area of the back of the animal, and a line from this device was passed under the skin to an electrode that was then implanted epidurally over the dorsal column. The rats were divided into three groups: control, 8-h stimulation, and 24-h stimulation, and behaviorally tested then euthanized for immunohistochemical analysis.
Results: The 8- and 24-h stimulation groups displayed significant behavioral improvement compared to the control group. Both SCS-stimulated groups exhibited significantly preserved tyrosine hydroxylase (TH)-positive fibers and neurons in the striatum and substantia nigra pars compacta (SNc), respectively, compared to the control group. Notably, the 24-h stimulation group showed significantly pronounced preservation of the striatal TH-positive fibers compared to the 8-h stimulation group. Moreover, the 24-h group demonstrated significantly reduced number of microglia in the striatum and SNc and increased laminin-positive area of the cerebral cortex compared to the control group.
Conclusions: This study demonstrated the behavioral and histological benefits of continuous SCS in a time-dependent manner in freely moving PD animals, possibly mediated by anti-inflammatory and angiogenic mechanisms. en-copyright= kn-copyright= en-aut-name=KuwaharaKen en-aut-sei=Kuwahara en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiTatsuya

kn-subtitle= en-abstract= kn-abstract=Although temporary clipping of the parent artery is an indispensable technique in clipping surgery for intracranial aneurysms, the permissive duration of temporary clipping is still not well known. The aim of this study is to confirm the safety of precise motor evoked potential (MEP) monitoring and to estimate the permissive duration of temporary clipping for middle cerebral artery (MCA) aneurysm based on precise MEP monitoring results. Under precise MEP monitoring via direct cortical stimulation every 30 seconds to 1 minute, surgeons released a temporary clip and waited for MEP amplitude to recover following severe (>50%) reduction of MEP amplitude during temporary clipping. Precise MEP monitoring was safely performed. Twenty-eight instances of temporary clipping were performed in 42 MCA aneurysm clipping surgeries. Because precise MEP monitoring could be used to determine when to release a temporary clip even with a severe reduction in MEP amplitude due to lengthy temporary clipping, no patients experienced permanent postoperative hemiparesis. Based on logistic regression analysis, if a temporary clip is applied for 312 seconds or more, there is a higher probability of a severe reduction in MEP amplitude. We should therefore release temporary clips after 5 minutes in order to avoid permanent postoperative hemiparesis. en-copyright= kn-copyright= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=epartment of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=epartment of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Stroke kn-keyword=Stroke END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=8 article-no= start-page=5063 end-page=5076 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurosurgery for brain metastasis from breast cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast cancer is the most common malignancy among women worldwide, and the main cause of death in patients with breast cancer is metastasis. Metastasis to the central nervous system occurs in 10% to 16% of patients with metastatic breast cancer, and this rate has increased because of recent advancements in systemic chemotherapy. Because of the various treatments available for brain metastasis, accurate diagnosis and evaluation for treatment are important. Magnetic resonance imaging (MRI) is one of the most reliable preoperative examinations not only for diagnosis of metastatic brain tumors but also for estimation of the molecular characteristics of the tumor based on radiographic information such as the number of lesions, solid or ring enhancement, and cyst formation. Surgical resection continues to play an important role in patients with a limited number of brain metastases and a relatively good performance status. A single brain metastasis is a good indication for surgical treatment followed by radiation therapy to obtain longer survival. Surgical removal is also considered for two or more lesions if neurological symptoms are caused by brain lesions of >3 cm with a mass effect or associated hydrocephalus. Although maximal safe resection with minimal morbidity is ideal in the surgical treatment of brain tumors, supramarginal resection can be achieved in select cases. With respect to the resection technique, en bloc resection is generally recommended to avoid leptomeningeal dissemination induced by piecemeal resection. An operating microscope, neuronavigation, and intraoperative neurophysiological monitoring are essential in modern neurosurgical procedures, including tumor resection. More recently, supporting surgical instruments have been introduced. The use of endoscopic surgery has dramatically increased, especially for intraventricular lesions and in transsphenoidal surgery. An exoscope helps neurosurgeons to comfortably operate regardless of patient positioning or anatomy. A tubular retractor can prevent damage to the surrounding brain tissue during surgery and is a useful instrument in combination with both an endoscope and exoscope. Additionally, 5-aminolevulinic acid (5-ALA) is a promising reagent for photodynamic detection of residual tumor tissue. In the near future, novel treatment options such as high-intensity focused ultrasound (HIFU), laser interstitial thermal therapy (LITT), oncolytic virus therapy, and gene therapy will be introduced. en-copyright= kn-copyright= en-aut-name=TomitaYusuke en-aut-sei=Tomita en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimazuYosuke en-aut-sei=Shimazu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Metastatic brain tumor kn-keyword=Metastatic brain tumor en-keyword=breast cancer kn-keyword=breast cancer en-keyword=neurosurgical technique kn-keyword=neurosurgical technique END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=3 article-no= start-page=119 end-page=123 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cerebral circulation improves with indirect bypass surgery combined with gene therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Angiogenesis involves new blood vessels sprouting from preexisting blood vessels. This process may serve to improve brain circulation. Moyamoya disease (MMD) is a cerebrovascular disorder causing intracranial stenosis which significantly reduces the blood supply to the brain. Mainly stroke is the first symptom of the disorder, so treatments that reduce the risk of stroke are used for patients with MMD. To prevent stroke for those with chronic cerebral hypoperfusion, more blood needs to flow to the brain, which was thought to be achieved by enhancing angiogenesis. Indirect bypass surgery, such as encephalo-myo-synangiosis (EMS), is used for revascularization. However, EMS alone sometimes cannot provide enough circulation to avoid ischemic strokes. The current study examined if EMS combined with high-mobility group box-1 (HMGB1) and vascular endothelial growth factor (VEGF) enhanced angiogenesis and increased cerebral circulation. The results indicated that HMGB1 administered with EMS increased angiogenesis through a VEGF-dependent mechanism. In addition, exercising and stem cell transplantation possess possible means to increase angiogenesis. Overall, EMS with gene therapy, maintaining fitness, and stem cell utilization may prevent or help one recover from stroke by enhancing brain angiogenesis. Thus, these treatments may be applicable for patients with MMD. This paper is a review article. Referred literature in this paper has been listed in the references section.

However, the roles of these proteins, particularly of MMP-9, in PTBE associated with benign meningiomas have not been elucidated. We investigated the association between clinical features and biological factors, such as VEGF and MMP-9, and the incidence of PTBE and edema index (EI) in 60 patients with benign meningiomas. In this study, supratentorial lesions were examined for evaluating the extent of PTBE in the surrounding normal brain tissue. VEGF and MMP-9 expression was immunohistochemically examined. Multivariate analysis revealed that the presence of pial blood supply (odds ratio [OR] 12.250; P = 0.0096) and VEGF (OR 7.683; P = 0.0155), but not MMP-9 (OR 1.178; P = 0.8113), expression are significant factors that independently predict the incidence of PTBE and influence EI. VEGF (P = 0.0397) and MMP-9 (P = 0.0057) expression correlates with the presence of pial blood supply. Moreover, tumors with high VEGF and MMP-9 expression had higher EIs than those with high expression of either (P = 0.030). Our findings suggest that MMP-9 expression was positively related to VEGF expression and pial blood supply and promoted the occurrence of PTBE by inducing the disruption of the arachnoid membrane and formation of pial blood supply. en-copyright= kn-copyright= en-aut-name=IwadoEiji en-aut-sei=Iwado en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakaHiroshi en-aut-sei=Kosaka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukaShinji en-aut-sei=Otsuka en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KambaraHirokazu en-aut-sei=Kambara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TamiyaTakashi en-aut-sei=Tamiya en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoSeiji en-aut-sei=Kondo en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil= kn-affil=Kagawa Univ, Fac Med, Dept Neurol Surg affil-num=7 en-affil= kn-affil=Univ Texas MD Anderson Canc Ctr, Dept Neurosurg affil-num=8 en-affil= kn-affil= en-keyword=matrix kn-keyword=matrix en-keyword=metalloproteinase-9 kn-keyword=metalloproteinase-9 en-keyword=meningioma kn-keyword=meningioma en-keyword=pial blood supply kn-keyword=pial blood supply en-keyword=peritumoral brain edema kn-keyword=peritumoral brain edema en-keyword=vascular endothelial growth factor kn-keyword=vascular endothelial growth factor END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=3 article-no= start-page=264 end-page=275 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proteomics-based analysis of invasion-related proteins in malignant gliomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=One of the insidious biological features of gliomas is their potential to extensively invade normal brain tissue, yet molecular mechanisms that dictate this locally invasive behavior remain poorly understood. To investigate the molecular basis of invasion by malignant gliomas, proteomic analysis was performed using a pair of canine glioma subclones - J3T-1 and J3T-2 - that show different invasion phenotypes in rat brains but have similar genetic backgrounds. Two-dimensional protein electrophoresis of whole-cell lysates of J3T-1 (angiogenesis-dependent invasion phenotype) and J3T-2 (angiogenesis-independent invasion phenotype) was performed. Twenty-two distinct spots were recognized when significant alteration was defined as more than 1.5-fold change in spot intensity between J3T-1 and J3T-2. Four proteins that demonstrated increased expression in J3T-1, and 14 proteins that demonstrated increased expression in J3T-2 were identified using liquid chromatography-mass spectrometry analysis. One of the proteins identified was annexin A2, which was expressed at higher levels in J3T-1 than in J3T-2. The higher expression of annexin A2 in J3T-1 was corroborated by quantitative RT-PCR of the cultured cells and immunohistochemical staining of the rat brain tumors. Moreover, immunohistochemical analysis of human glioblastoma specimens showed that annexin A2 was expressed at high levels in the tumor cells that formed clusters around dilated vessels. These results reveal differences in the proteomic profiles between these two cell lines that might correlate with their different invasion profiles. Thus, annexin A2 may be related to angiogenesis-dependent invasion. en-copyright= kn-copyright= en-aut-name=MaruoTomoko en-aut-sei=Maruo en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanzakiHirotaka en-aut-sei=Kanzaki en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueSatoshi en-aut-sei=Inoue en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnishiManabu en-aut-sei=Onishi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaKoichi en-aut-sei=Yoshida en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KambaraHirokazu en-aut-sei=Kambara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OuchidaMamoru en-aut-sei=Ouchida en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShimizuKenji en-aut-sei=Shimizu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TamaruSeiji en-aut-sei=Tamaru en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ChioccaE.

We investigated the anti-glioma mechanisms of cilengitide (EMD121974), an v3 integrin inhibitor, utilizing the novel invasive glioma models, J3T-1 and J3T-2. Immunohistochemical staining of cells in culture and brain tumors in rats revealed positive v3 integrin expression in J3T-2 cells and tumor endothelial cells, but not in J3T-1 cells. Established J3T-1 and J3T-2 orthotopic gliomas in athymic rats were treated with cilengitide or solvent. J3T-1 gliomas showed perivascular tumor cluster formation and angiogenesis, while J3T-2 gliomas showed diffuse single-cell infiltration without obvious angiogenesis. Cilengitide treatment resulted in a significantly decreased diameter of the J3T-1 tumor vessel clusters and its core vessels when compared with controls, while an anti-invasive effect was shown in the J3T-2 glioma with a significant reduction of diffuse cell infiltration around the tumor center. The survival of cilengitide-treated mice harboring J3T-1 tumors was significantly longer than that of control animals (median survival: 57.5 days and 31.8 days, respectively, P<0.005), while cilengitide had no effect on the survival of mice with J3T-2 tumors (median survival: 48.9 days and 48.5, P=0.69). Our results indicate that cilengitide exerts a phenotypic anti-tumor effect by inhibiting angiogenesis and glioma cell invasion. These two mechanisms are clearly shown by the experimental treatment of two different animal invasive glioma models. en-copyright= kn-copyright= en-aut-name=OnishiManabu en-aut-sei=Onishi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaKoichi en-aut-sei=Yoshida en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InoueSatoshi en-aut-sei=Inoue en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MichiueHiroyuki en-aut-sei=Michiue en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChioccaE.

The aim of this study was to gather real data in 2018 on complications related to cranial implants in neurosurgery. The survey population consisted of 1103 institutes supplying neurosurgical treatment. The survey consisted of two-stage questionnaire. First the incidence of complications was investigated, then the secondary questionnaire was e-mailed to the respondents about the detailed of the complications. As the result, the annual incidence of complications related to cranial implants was 0.558% in Japan. Titanium plate and mesh were used predominantly in craniotomy and cranioplasty, respectively. The second survey collected data on 449 cases with complications (infection: 63%, implant exposure: 46%, multiple answer). Postoperative infection was associated with male sex, brain tumor, short interval between surgery and complication, usage of ceramics, hydroxyapatite, resin, and artificial dura, hyponutrition, multiple surgeries, dirty wound, and sinusitis as patient factors, and CSF leakage, ruptured sutures, and sinus maltreatment as surgery factors. Meanwhile, long hospital stay was associated with age, male sex, mRS 3?5 before complication, short interval between initial surgery and complication, large craniotomy, long operative time, usage of ceramics and artificial dura, multiple surgeries and dirty wound as patient factors, ruptured suture as a surgical factor, and bacterial infection, especially MRSA infection, as the complication and treatment consisting of removal as complication factors. In conclusion, this is the first Japanese national survey on complications related to cranial implants in neurosurgery. It is important to recall that complications may arise years after surgery and to be aware of the risk factors associated with complications. en-copyright= kn-copyright= en-aut-name=YASUHARATakao en-aut-sei=YASUHARA en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MURAISatoshi en-aut-sei=MURAI en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MIKUNINobuhiro en-aut-sei=MIKUNI en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MIYAMOTOSusumu en-aut-sei=MIYAMOTO en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DATEIsao en-aut-sei=DATE en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Sapporo Medical University kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Kyoto University kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesCranial implants are commonly used throughout the world, yet the data on complications remain partly clarified.

It is important to recall that complications may arise years after surgery and to be aware of the risk factors associated with complications. kn-affil= en-keyword=artificial bone kn-keyword=artificial bone en-keyword=cranioplasty kn-keyword=cranioplasty en-keyword=infection kn-keyword=infection en-keyword=re-operation kn-keyword=re-operation en-keyword=titanium plate kn-keyword=titanium plate END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=29 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Differentiated glioblastoma cells accelerate tumor progression by shaping the tumor microenvironment via CCN1-mediated macrophage infiltration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioblastoma (GBM) is the most lethal primary brain tumor characterized by significant cellular heterogeneity, namely tumor cells, including GBM stem-like cells (GSCs) and differentiated GBM cells (DGCs), and non-tumor cells such as endothelial cells, vascular pericytes, macrophages, and other types of immune cells. GSCs are essential to drive tumor progression, whereas the biological roles of DGCs are largely unknown. In this study, we focused on the roles of DGCs in the tumor microenvironment. To this end, we extracted DGC-specific signature genes from transcriptomic profiles of matched pairs of in vitro GSC and DGC models. By evaluating the DGC signature using single cell data, we confirmed the presence of cell subpopulations emulated by in vitro culture models within a primary tumor. The DGC signature was correlated with the mesenchymal subtype and a poor prognosis in large GBM cohorts such as The Cancer Genome Atlas and Ivy Glioblastoma Atlas Project. In silico signaling pathway analysis suggested a role of DGCs in macrophage infiltration. Consistent with in silico findings, in vitro DGC models promoted macrophage migration. In vivo, coimplantation of DGCs and GSCs reduced the survival of tumor xenograft-bearing mice and increased macrophage infiltration into tumor tissue compared with transplantation of GSCs alone. DGCs exhibited a significant increase in YAP/TAZ/TEAD activity compared with GSCs. CCN1, a transcriptional target of YAP/TAZ, was selected from the DGC signature as a candidate secreted protein involved in macrophage recruitment. In fact, CCN1 was secreted abundantly from DGCs, but not GSCs. DGCs promoted macrophage migration in vitro and macrophage infiltration into tumor tissue in vivo through secretion of CCN1. Collectively, these results demonstrate that DGCs contribute to GSC-dependent tumor progression by shaping a mesenchymal microenvironment via CCN1-mediated macrophage infiltration. This study provides new insight into the complex GBM microenvironment consisting of heterogeneous cells. en-copyright= kn-copyright= en-aut-name=UnedaAtsuhito en-aut-sei=Uneda en-aut-mei=Atsuhito

kn-title=Mobile endovascular therapy for acute treatment of ruptured vertebral artery dissecting aneurysm in multiple hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The patients with ruptured vertebral artery dissecting aneurysm (rVADA) should be treated as early as possible because VADA carries extremely high risk of rebleeding in the acute phase. We have established a mobile endovascular strategy for the patients with rVADA between our flagship center and its affiliated local hospitals. We introduced and reviewed our mobile endovascular therapy in this study.
Methods
We retrospectively evaluated 98 consecutive patients who underwent endovascular surgery for rVADA from 2000 to 2018 at our institution or five affiliated hospitals. When each patient was initially transported to the local affiliated hospitals, neuroendovascular surgeons traveled directly to the affiliated hospital from the flagship center in order to treat the patient there. Clinical outcomes using modified Rankin Scale at 6 months after treatment, radiological results, and procedure-related complications were reviewed to justify our mobile endovascular strategy.
Results
All aneurysms were cured successfully by internal trapping. Favorable outcome was achieved in 61 patients (62.2%) even though 53 patients (54.1%) had presented with severe subarachnoid hemorrhage. Overall mortality rate, treatment-related mortality rate, and treatment related complication rate were 18.4% (18/98), 0%, and 16% (16/98), respectively. There were no differences in clinical and radiological outcomes between the patients treated in the flagship center and those who treated in the affiliated hospitals. Treatment in the affiliated hospital was not a predictive factor of unfavorable outcome in our multivariate analysis, and elderly age (>= 60) was negatively associated with favorable outcome.
Conclusions
Our results prove the efficacy and safety of mobile endovascular therapy for the treatment of rVADA in the ultra-acute stage. Mobile endovascular therapy may work well in the acute treatment of rVADAs in the certain circumstance. en-copyright= kn-copyright= en-aut-name=KidaniNaoya en-aut-sei=Kidani en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TerasakaKaoru en-aut-sei=Terasaka en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakashimaHiroyuki en-aut-sei=Nakashima en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TokunagaKoji en-aut-sei=Tokunaga en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiKazuki en-aut-sei=Kobayashi en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KambaraHirokazu en-aut-sei=Kambara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Kure Kyosai Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Okayama Kyokuto Hospital kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Okayama City Municipal Hospital kn-affil= affil-num=6 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=7 article-no= start-page=393 end-page=396 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Evaluation of the Safety and Feasibility of Adenosine-assisted Clipping Surgery for Unruptured Cerebral Aneurysms: Study Protocol en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effectiveness of adenosine-induced flow arrest in surgical clipping for the cerebral aneurysms with difficulties in temporary clip placement to the proximal main trunk has been reported.

with Mild Stimulation Intensity Exerts Anti-Inflammatory and Neuroprotective Effects in Parkinson's Disease Model Rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The major surgical treatment for Parkinson's disease (PD) is deep brain stimulation (DBS), but a less invasive treatment is desired. Vagus nerve stimulation (VNS) is a relatively safe treatment without cerebral invasiveness. In this study, we developed a wireless controllable electrical stimulator to examine the efficacy of VNS on PD model rats. Methods: Adult female Sprague-Dawley rats underwent placement of a cuff-type electrode and stimulator on the vagus nerve. Following which, 6-hydroxydopamine (6-OHDA) was administered into the left striatum to prepare a PD model. VNS was started immediately after 6-OHDA administration and continued for 14 days. We evaluated the therapeutic effects of VNS with behavioral and immunohistochemical outcome assays under different stimulation intensity (0.1, 0.25, 0.5 and 1 mA). Results: VNS with 0.25-0.5 mA intensity remarkably improved behavioral impairment, preserved dopamine neurons, reduced inflammatory glial cells, and increased noradrenergic neurons. On the other hand, VNS with 0.1 mA and 1 mA intensity did not display significant therapeutic efficacy. Conclusions: VNS with 0.25-0.5 mA intensity has anti-inflammatory and neuroprotective effects on PD model rats induced by 6-OHDA administration. In addition, we were able to confirm the practicality and effectiveness of the new experimental device. en-copyright= kn-copyright= en-aut-name=KinIttetsu en-aut-sei=Kin en-aut-mei=Ittetsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AgariTakashi en-aut-sei=Agari en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkazakiMihoko en-aut-sei=Okazaki en-aut-mei=Mihoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HosomotoKakeru en-aut-sei=Hosomoto en-aut-mei=Kakeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkazakiYosuke en-aut-sei=Okazaki en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawauchiSatoshi en-aut-sei=Kawauchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KuwaharaKen en-aut-sei=Kuwahara en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MorimotoJun en-aut-sei=Morimoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=UmakoshiMichiari en-aut-sei=Umakoshi en-aut-mei=Michiari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=TomitaYousuke en-aut-sei=Tomita en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TajiriNaoki en-aut-sei=Tajiri en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=BorlonganCesario, V en-aut-sei=Borlongan en-aut-mei=Cesario, V kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Tokyo Metropolitan Neurological Hospital kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=15 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=16 en-affil=Department of Neurophysiology and Brain Science and Medical School, Graduate School of Medical Sciences and Medical School, Nagoya City University kn-affil= affil-num=17 en-affil=Department of Neurosurgery and Brain Repair, University of South Florida Morsani College of Medicine, 12901 Bruce B.

Thus the development of therapeutic neuroprotection and neurorescue strategies to mitigate disease progression is important. In this study we evaluated the neuroprotective/rescue effects of erythropoietin Fc fusion protein (EPO-Fc) and carbamylated erythropoietin Fe fusion protein (CEPO-Fc) in a rat model of Parkinson's disease. Adult female Sprague-Dawley rats received intraperitoneal injection of EPO-Fc, CEPO-Fc or PBS. Behavioral evaluations consisted of rota-rod, cylinder and amphetamine-induced rotation tests. In the neuroprotection experiment, the CEPO-Fc group demonstrated significant improvement compared with the EPO-Fc group on the amphetamine-induced rotation test throughout the four-week follow-up period. Histologically, significantly more tyrosine hydroxylase (TH)-positive neurons were recognized in the substantia nigra (SN) pars compacta in the CEPO-Fc group than in the PBS and EPO-Fc groups. In the neurorescue experiment, rats receiving CEPO-Fc showed significantly better behavioural scores than those receiving PBS. The histological data concerning striatum also showed that the CEPO-Fc group had significantly better preservation of TH-positive fibers compared to the PBS and EPO-Fc groups. Importantly, there were no increases in hematocrit or hemoglobin levels in the CEPO-Fc group in either the neuroprotection or the neurorescue experiments. In conclusion, the newly developed CEPO-Fc might confer neuroprotective and neurorescue benefits in a rat model of Parkinson's disease without the side effects associated with polycythemia. CEPO-Fc might be a therapeutic tool for patients with Parkinson's disease. en-copyright= kn-copyright= en-aut-name=TayraJudith Thomas en-aut-sei=Tayra en-aut-mei=Judith Thomas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AgariTakashi en-aut-sei=Agari en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KadotaTomohito en-aut-sei=Kadota en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WangFeifei en-aut-sei=Wang en-aut-mei=Feifei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KikuchiYoichiro en-aut-sei=Kikuchi en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LiangHanbai en-aut-sei=Liang en-aut-mei=Hanbai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShinkoAiko en-aut-sei=Shinko en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WakamoriTakaaki en-aut-sei=Wakamori en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=VcelarBrigitta en-aut-sei=Vcelar en-aut-mei=Brigitta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WeikRobert en-aut-sei=Weik en-aut-mei=Robert kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=7 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=8 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=9 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=10 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=11 en-affil= kn-affil=Polymun Sci GmbH affil-num=12 en-affil= kn-affil=Polymun Sci GmbH affil-num=13 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg en-keyword=Carbamylated erythropoietin kn-keyword=Carbamylated erythropoietin en-keyword=Dopamine kn-keyword=Dopamine en-keyword=Neuroprotection kn-keyword=Neuroprotection en-keyword=Neurorescue kn-keyword=Neurorescue en-keyword=Parkinson's disease kn-keyword=Parkinson's disease END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=9 article-no= start-page=549 end-page=556 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ultra-high-molecular-weight Polyethylene (UHMWPE) Wing Method for Strong Cranioplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=We developed a new cranioplasty method that utilizes artificial bone made of ultra-high-molecular-weight polyethylene, with a wedge-shaped edge (UHMWPE Wing). This study shows the methods and data of case series and finite element analyses with the UHMWPE Wing. A circumferential wing was preoperatively designed for a custom-made artificial bone made of UHMWPE to achieve high fixed power and to minimize the usage of cranial implants. Here, we present 4 years of follow-up data and finite element analyses for patients treated with the UHMWPE Wing between February 2015 and February 2019. Eighteen consecutive patients underwent cranioplasty using our UHMWPE Wing design. There were no postoperative adverse events in 17 of the patients for at least 18 months. One case of hydrocephalus experienced screw loosening and graft uplift due to shunt malfunction. Placement of a ventriculo-peritoneal shunt immediately returned the artificial bone to normal position. Finite element analyses revealed that a model using the UHMWPE Wing had the highest withstand load and lowest deformation. This is the first report on the UHMWPE Wing method. This method may enable clinicians to minimize dead space and achieve high strength in cranioplasty. en-copyright= kn-copyright= en-aut-name=KobayashiKazuki en-aut-sei=Kobayashi en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YukiueTadato en-aut-sei=Yukiue en-aut-mei=Tadato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaHideyuki en-aut-sei=Yoshida en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuboiNobushige en-aut-sei=Tsuboi en-aut-mei=Nobushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYuu en-aut-sei=Takahashi en-aut-mei=Yuu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MakinoKeigo en-aut-sei=Makino en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimuraRyu en-aut-sei=Kimura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MizutaRyo en-aut-sei=Mizuta en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OgawaTomoyuki en-aut-sei=Ogawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagayamaNoriyuki en-aut-sei=Nagayama en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=10 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=11 en-affil=Industrial Technology Center of Okayama Prefecture kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=artificial bone kn-keyword=artificial bone en-keyword=cranioplasty kn-keyword=cranioplasty en-keyword=finite element analyses kn-keyword=finite element analyses en-keyword=ultra-high-molecular-weight polyethylene kn-keyword=ultra-high-molecular-weight polyethylene END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=10 article-no= start-page=607 end-page=618 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spinal Surgery after Bilateral Subthalamic Stimulation for Patients with Parkinson's Disease: A Retrospective Outcome Analysis of Pain and Functional Control en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson's disease (PD) patients often suffer from spinal diseases requiring surgeries, although the risk of complications is high. There are few reports on outcomes after spinal surgery for PD patients with deep brain stimulation (DBS). The objective of this study was to explore the data on spinal surgery for PD patients with precedent DBS. We evaluated 24 consecutive PD patients with 28 spinal surgeries from 2007 to 2017 who received at least a 2-year follow-up. The characteristics and outcomes of PD patients after spinal surgery were compared to those of 156 non-PD patients with degenerative spinal diseases treated in 2013-2017. Then, the characteristics, outcomes, and spinal alignment of PD patients receiving DBS were analyzed in degenerative spinal/ lumbar diseases. The mean age at the time of spinal surgery was 68 years. The Hoehn and Yahr score regarding PD was stage 1 for 8 patients, stage 2 for 2 patients, stage 3 for 8 patients, stage 4 for 10 patients, and stage 5 for 0 patient. The median preoperative L-DOPA equivalent daily dose was 410 mg. Thirteen patients (46%) received precedent subthalamic nucleus (STN) DBS. Lumbar lesions with pain were common, and operation and anesthesia times were long in PD patients. Pain and functional improvement of PD patients persisted for 2 years after surgery with a higher complication rate than for non-PD patients. PD patients with STN DBS maintained better lumbar lordosis for 2 years after spinal surgery. STN DBS significantly maintained spinal alignment with subsequent pain and functional amelioration 2 years after surgery. The outcomes of spinal surgery for PD patients might be favorably affected by thorough treatment for PD including DBS. en-copyright= kn-copyright= en-aut-name=UmakoshiMichiari en-aut-sei=Umakoshi en-aut-mei=Michiari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoJun en-aut-sei=Morimoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraiSatoshi en-aut-sei=Murai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiYasuyuki en-aut-sei=Miyoshi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=abnormal posture kn-keyword=abnormal posture en-keyword=lumbago kn-keyword=lumbago en-keyword=neuromodulation kn-keyword=neuromodulation en-keyword=pain kn-keyword=pain en-keyword=spinal alignment kn-keyword=spinal alignment END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue= article-no= start-page=57 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202246 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Implications of immune cells in oncolytic herpes simplex virotherapy for glioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite current progress in treatment, glioblastoma (GBM) remains a lethal primary malignant tumor of the central nervous system. Although immunotherapy has recently achieved remarkable survival effectiveness in multiple malignancies, none of the immune checkpoint inhibitors (ICIs) for GBM have shown anti-tumor efficacy in clinical trials. GBM has a characteristic immunosuppressive tumor microenvironment (TME) that results in the failure of ICIs. Oncolytic herpes simplex virotherapy (oHSV) is the most advanced United States Food and Drug Administration-approved virotherapy for advanced metastatic melanoma patients. Recently, another oHSV, Delytact?, was granted conditional approval in Japan against GBM, highlighting it as a promising treatment. Since oncolytic virotherapy can recruit abundant immune cells and modify the immune TME, oncolytic virotherapy for immunologically cold GBM will be an attractive therapeutic option for GBM. However, as these immune cells have roles in both anti-tumor and anti-viral immunity, fine-tuning of the TME using oncolytic virotherapy will be important to maximize the therapeutic efficacy. In this review, we discuss the current knowledge of oHSV, with a focus on the role of immune cells as friend or foe in oncolytic virotherapy. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YooJi Young en-aut-sei=Yoo en-aut-mei=Ji Young kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuToshihiko en-aut-sei=Shimizu en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaurBalveen en-aut-sei=Kaur en-aut-mei=Balveen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurosurgery, McGovern Medical School, University of Texas Health Science Center at Houston kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Matsuyama Shimin Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Hamamatsu University School of Medicine kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurosurgery, McGovern Medical School, University of Texas Health Science Center at Houston kn-affil= en-keyword=Oncolytic virus kn-keyword=Oncolytic virus en-keyword=Immune cells kn-keyword=Immune cells en-keyword=Glioma kn-keyword=Glioma END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220824 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transplantation of modified human bone marrow-derived stromal cells affords therapeutic effects on cerebral ischemia in rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims SB623 cells are human bone marrow stromal cells transfected with Notch1 intracellular domain. In this study, we examined potential regenerative mechanisms underlying stereotaxic transplantation of SB623 cells in rats with experimental acute ischemic stroke. Methods We prepared control group, empty capsule (EC) group, SB623 cell group (SB623), and encapsulated SB623 cell (eSB623) group. Transient middle cerebral artery occlusion (MCAO) was performed on day 0, and 24 h after MCAO, stroke rats received transplantation into the envisioned ischemic penumbra. Modified neurological severity score (mNSS) was evaluated, and histological evaluations were performed. Results In the mNSS, SB623 and eSB623 groups showed significant improvement compared to the other groups. Histological analysis revealed that the infarction area in SB623 and eSB623 groups was reduced. In the eSB623 group, robust cell viability and neurogenesis were detected in the subventricular zone that increased significantly compared to all other groups. Conclusion SB623 cells with or without encapsulation showed therapeutic effects on ischemic stroke. Encapsulated SB623 cells showed enhanced neurogenesis and increased viability inside the capsules. This study reveals the mechanism of secretory function of transplanted SB623 cells, but not cell-cell interaction as primarily mediating the cells' functional benefits in ischemic stroke.

modified bone marrow-derived stromal cells (SB623) and voluntary exercise with running wheel in a rat model of ischemic stroke en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　Mesenchymal stromal cell (MSC) transplantation therapy is a promising therapy for stroke patients. In parallel, rehabilitation with physical exercise could ameliorate stroke-induced neurological impairment. In this study, we aimed to clarify whether combination therapy of intracerebral transplantation of human modified bone marrow-derived MSCs, SB623 cells, and voluntary exercise with running wheel (RW) could exert synergistic therapeutic effects on a rat model of ischemic stroke.
Methods　Wistar rats received right transient middle cerebral artery occlusion (MCAO). Voluntary exercise (Ex) groups were trained in a cage with RW from day 7 before MCAO. SB623 cells (4.0 x 10(5) cells/5 mu l) were stereotactically injected into the right striatum at day 1 after MCAO. Behavioral tests were performed at day 1, 7, and 14 after MCAO using the modified Neurological Severity Score (mNSS) and cylinder test. Rats were euthanized at day 15 after MCAO for mRNA level evaluation of ischemic infarct area, endogenous neurogenesis, angiogenesis, and expression of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF). The rats were randomly assigned to one of the four groups: vehicle, Ex, SB623, and SB623 + Ex groups.
Results　SB623 + Ex group achieved significant neurological recovery in mNSS compared to the vehicle group (p < 0.05). The cerebral infarct area of SB623 + Ex group was significantly decreased compared to those in all other groups (p < 0.05). The number of BrdU/Doublecortin (Dcx) double-positive cells in the subventricular zone (SVZ) and the dentate gyrus (DG), the laminin-positive area in the ischemic boundary zone (IBZ), and the mRNA level of BDNF and VEGF in SB623 + Ex group were significantly increased compared to those in all other groups (p < 0.05).
Conclusions　This study suggests that combination therapy of intracerebral transplantation SB623 cells and voluntary exercise with RW achieves robust neurological recovery and synergistically promotes endogenous neurogenesis and angiogenesis after cerebral ischemia, possibly through a mechanism involving the up-regulation of BDNF and VEGF. en-copyright= kn-copyright= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaseTakayuki en-aut-sei=Nagase en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawauchiSatoshi en-aut-sei=Kawauchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugaharaChiaki en-aut-sei=Sugahara en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkazakiYosuke en-aut-sei=Okazaki en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HosomotoKakeru en-aut-sei=Hosomoto en-aut-mei=Kakeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TajiriNaoki en-aut-sei=Tajiri en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BorlonganCesar V. en-aut-sei=Borlongan en-aut-mei=Cesar V. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Neurophysiology and Brain Science, Nagoya City University Graduate School of Medical Sciences and Medical School kn-affil= affil-num=11 en-affil=Department of Neurosurgery and Brain Repair, Morsani College of Medicine, University of South Florida kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cerebral ischemic infarct kn-keyword=Cerebral ischemic infarct en-keyword=Rehabilitation kn-keyword=Rehabilitation en-keyword=Regenerative medicine kn-keyword=Regenerative medicine en-keyword=SB623 kn-keyword=SB623 en-keyword=Voluntary exercise kn-keyword=Voluntary exercise END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=2 article-no= start-page=594 end-page=603 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Continuous vagus nerve stimulation exerts beneficial effects on rats with experimentally induced Parkinson's disease: Evidence suggesting involvement of a vagal afferent pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Vagus nerve stimulation (VNS) exerts neuroprotective and anti-inflammatory effects in preclinical models of central nervous system disorders, including Parkinson's disease (PD). VNS setting applied for experimental models is limited into single-time or intermittent short-duration stimulation. We developed a VNS device which could deliver continuous stimulation for rats. To date, the effects of vagal afferent-or efferent-selective stimulation on PD using continuous electrical stimulation remains to be determined.
Objective: To investigate the effects of continuous and selective stimulation of vagal afferent or efferent fiber on Parkinsonian rats.
Methods: Rats were divided into 5 group: intact VNS, afferent VNS (left VNS in the presence of left caudal vagotomy), efferent VNS (left VNS in the presence of left rostral vagotomy), sham, vagotomy. Rats un-derwent the implantation of cuff-electrode on left vagus nerve and 6-hydroxydopamine administration into the left striatum simultaneously. Electrical stimulation was delivered just after 6-OHDA adminis-tration and continued for 14 days. In afferent VNS and efferent VNS group, the vagus nerve was dissected at distal or proximal portion of cuff-electrode to imitate the selective stimulation of afferent or efferent vagal fiber respectively.
Results: Intact VNS and afferent VNS reduced the behavioral impairments in cylinder test and methamphetamine-induced rotation test, which were accompanied by reduced inflammatory glial cells in substantia nigra with the increased density of the rate limiting enzyme in locus coeruleus. In contrast, efferent VNS did not exert any therapeutic effects.
Conclusion: Continuous VNS promoted neuroprotective and anti-inflammatory effect in experimental PD, highlighting the crucial role of the afferent vagal pathway in mediating these therapeutic outcomes. en-copyright= kn-copyright= en-aut-name=HosomotoKakeru en-aut-sei=Hosomoto en-aut-mei=Kakeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiTatsuya

kn-subtitle= en-abstract= kn-abstract=It has long been considered that central nervous system would not regenerate after injury, but this concept has recently been changing due to the development of neuroscience research. Cell grafting, gene transfer and neurotrophic factor administration into the brain and spinal cord are the examples of methods to perform protection and repair. These techniques are expected to be applied to certain neurological disorders such as Parkinson's disease, cerebral ischemia and spinal cord injury. Parkinson's disease is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the nigrostriatal system. Fetal neurons, chromaffin cells, cell lines, certain genes, neural stem cells, ES cells and bone marrow cells have been investigated as donor cells and vectors to treat Parkinson's disease. This review will summarize the history of neural transplantation in Parkinson's disease and features and prospects of each donor will be discussed. en-copyright= kn-copyright= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name=伊達勲 kn-aut-sei=伊達 kn-aut-mei=勲 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯学総合研究科　神経病態外科学 en-keyword=Parkinson's disease kn-keyword=Parkinson's disease en-keyword=neural transplantation kn-keyword=neural transplantation en-keyword=regeneration kn-keyword=regeneration END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=9 article-no= start-page=1153 end-page=1160 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel 3D-CT evaluation of carotid stent volume: greater chronological expansion of stents in patients with vulnerable plaques en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although self-expanding carotid stents may dilate gradually, the degrees of residual stenosis have been quantified by the NASCET criteria, which is too simple to reflect the configuration of the stented artery. We measured the volumes of the stent lumens chronologically by 3D-CT in patients after carotid artery stenting (CAS), and analyzed the correlations between the volume change and medical factors. Fourteen patients with carotid artery stenosis were treated using self-expanding, open-cell stents. All patients underwent preoperative plaque MRI (magnetization-prepared rapid acquisition gradient-echo, MPRAGE) and chronological 3D-CT examinations of their stents immediately after their placement and 1 day, 1 week, and 1 month after the procedure. The volume of the stent lumen was measured using a 3D workstation. The correlations between stent volume and various factors including the presence of underlying diseases, plaque characteristics, and the results of the CAS procedure were analyzed. Stent volume gradually increased in each case and had increased by 1.04-1.55 (mean, 1.25)-fold at 1 postoperative month. The presence of underlying medical diseases, plaque length, the degree of residual stenosis immediately after CAS, and plaque calcification did not have an impact on the change in stent volume. On the other hand, the stent volume increase was significantly larger in the patients with vulnerable plaques that demonstrated high MPRAGE signal intensity (P < 0.05). A 3D-CT examination is useful for precisely measuring stent volume. Self-expanding stents in carotid arteries containing vulnerable plaques expand significantly more than those without such plaques in a follow-up period. en-copyright= kn-copyright= en-aut-name=ItamiHisakazu en-aut-sei=Itami en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TokunagaKoji en-aut-sei=Tokunaga en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkumaYu en-aut-sei=Okuma en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IdaKentaro en-aut-sei=Ida en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Dept Neurol Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=2 en-affil= kn-affil=Okayama Univ, Dept Neurol Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Okayama Univ, Dept Neurol Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=4 en-affil= kn-affil=Okayama Univ, Dept Neurol Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=5 en-affil= kn-affil=Okayama Univ, Dept Neurol Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=6 en-affil= kn-affil=Okayama Univ, Dept Radiol, Grad Sch Med Dent & Pharmaceut Sci affil-num=7 en-affil= kn-affil=Okayama Univ, Dept Neurol Surg, Grad Sch Med Dent & Pharmaceut Sci en-keyword=Carotid artery stenting kn-keyword=Carotid artery stenting en-keyword=Carotid stenosis kn-keyword=Carotid stenosis en-keyword=Plaque MRI kn-keyword=Plaque MRI en-keyword=3D-CT kn-keyword=3D-CT END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=8 article-no= start-page=437 end-page=444 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The integrin inhibitor cilengitide enhances the anti-glioma efficacy of vasculostatin-expressing oncolytic virus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oncolytic viral (OV) therapy has been considered as a promising treatment modality for brain tumors. Vasculostatin, the fragment of brain-specific angiogenesis inhibitor-1, shows anti-angiogenic activity against malignant gliomas. Previously, a vasculostatin-expressing oncolytic herpes simplex virus-1, Rapid Antiangiogenesis Mediated By Oncolytic virus (RAMBO), was reported to have a potent antitumor effect. Here, we investigated the therapeutic efficacy of RAMBO and cilengitide, an integrin inhibitor, combination therapy for malignant glioma. In vitro, tube formation was significantly decreased in RAMBO and cilengitide combination treatment compared with RAMBO or cilengitide monotherapy. Moreover, combination treatment induced a synergistic suppressive effect on endothelial cell migration compared with the control virus. RAMBO, combined with cilengitide, induced synergistic cytotoxicity on glioma cells. In the caspase-8 and -9 assays, the relative absorption of U87 Delta EGFR cell clusters treated with cilengitide and with RAMBO was significantly higher than that of those treated with control. In addition, the activity of caspase 3/7 was significantly increased with combination therapy. In vivo, there was a significant increase in the survival of mice treated with combination therapy compared with RAMBO or cilengitide monotherapy. These results indicate that cilengitide enhanced vasculostatin-expressing OV therapy for malignant glioma and provide a rationale for designing future clinical trials combining these two agents. en-copyright= kn-copyright= en-aut-name=FujiiK en-aut-sei=Fujii en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurozumiK en-aut-sei=Kurozumi en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IchikawaT en-aut-sei=Ichikawa en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnishiM en-aut-sei=Onishi en-aut-mei=M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimazuY en-aut-sei=Shimazu en-aut-mei=Y kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshidaJ en-aut-sei=Ishida en-aut-mei=J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChioccaEA en-aut-sei=Chiocca en-aut-mei=EA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KaurB en-aut-sei=Kaur en-aut-mei=B kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateI en-aut-sei=Date en-aut-mei=I kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=7 en-affil= kn-affil=Brigham & Womens Hosp, Dept Neurosurg affil-num=8 en-affil= kn-affil=Ohio State Univ, Dept Neurol Surg, Dardinger Lab Neurooncol & Neurosci affil-num=9 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg en-keyword=cilengitide kn-keyword=cilengitide en-keyword=glioma kn-keyword=glioma en-keyword=oncolytic viral therapy kn-keyword=oncolytic viral therapy END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=4 article-no= start-page=415 end-page=420 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cognitive functions in Parkinson's disease: Relation to disease severity and hallucination en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: We wished to relate severity of Parkinson's disease (PD) with cognitive function in relation to cerebral blood flow (CBF). Methods: Eighty-one consecutive PD patients were enrolled in this study. We used Mini-Mental State Examination (MMSE) and Wechsler Adult Intelligence Scale-Third edition (WAIS-III) to evaluate cognitive functions, and three-dimensional stereotactic ROI template (3DSRT) and Statistical Parametric Mapping (SPM) 8 to evaluate single photon emission CT (SPECT) recordings of regional CBF. Results: The mean MMSE score of PD patients was 27.4 +/- 2.4. The scores of most patients were higher than 23/30. On the other hand, the mean Full-scale IQ of PD patients was 88.4 +/- 17.3 in WAIS-III, which was lower than that of normal controls. In particular, visuospatial function score of most patients was lower. There was significant correlation between cognitive scores and Hoehn & Yahr stage and hallucinatory episodes. PD Patients with stage III and IV showed significant deterioration in cognitive functions compared to stage II patients. Analysis of CBF revealed relative reductions in perfusion in the cerebral cortex relative to that in normal control. SPM 8 showed that cognitive functions in PD patients were positively correlated with rCBF in the thalamus and cingulate gyrus. Conclusions: This is the study to demonstrate the cognitive impairments in PD patients using WAIS-III. Visuospatial dysfunction might be caused by decrease in rCBF in the parietal and occipital lobes and dorsolateral prefrontal cortex. The severity of cognitive impairments in PD patients was correlated with disease severity and hallucinatory episodes. en-copyright= kn-copyright= en-aut-name=WakamoriTakaaki en-aut-sei=Wakamori en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AgariTakashi en-aut-sei=Agari en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoAkihiko en-aut-sei=Kondo en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShinkoAiko en-aut-sei=Shinko en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FurutaTomohisa en-aut-sei=Furuta en-aut-mei=Tomohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=7 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=8 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=9 en-affil= kn-affil=Kibi Int Univ, Dept Psychol affil-num=10 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg en-keyword=Parkinson's disease kn-keyword=Parkinson's disease en-keyword=Cognitive functions kn-keyword=Cognitive functions en-keyword=Disease severity kn-keyword=Disease severity en-keyword=Hallucinations kn-keyword=Hallucinations en-keyword=SPECT kn-keyword=SPECT END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=292 end-page=302 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Integrin Inhibitor Suppresses Bevacizumab-Induced Glioma Invasion en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioblastoma is known to secrete high levels of vascular endothelial growth factor (VEGF), and clinical studies with bevacizumab, a monoclonal antibody to VEGF, have demonstrated convincing therapeutic benefits in glioblastoma patients. However, its induction of invasive proliferation has also been reported. We examined the effects of treatment with cilengitide, an integrin inhibitor, on bevacizumab-induced invasive changes in glioma. U87 Delta EGFR cells were stereotactically injected into the brain of nude mice or rats. Five days after tumor implantation, cilengitide and bevacizumab were administered intraperitoneally three times a week. At 18 days after tumor implantation, the brains were removed and observed histopathologically. Next, the bevacizumab and cilengitide combination group was compared to the bevacizumab monotherapy group using microarray analysis. Bevacizumab treatment led to increased cell invasion in spite of decreased angiogenesis. When the rats were treated with a combination of bevacizumab and cilengitide, the depth of tumor invasion was significantly less than with only bevacizumab. Pathway analysis demonstrated the inhibition of invasion-associated genes such as the integrin-mediated cell adhesion pathway in the combination group. This study showed that the combination of bevacizumab with cilengitide exerted its anti-invasive effect. The elucidation of this mechanism might contribute to the treatment of bevacizumab-refractory glioma. en-copyright= kn-copyright= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiManabu en-aut-sei=Onishi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimazuYosuke en-aut-sei=Shimazu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkaTetsuo en-aut-sei=Oka en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=7 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=8 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg END start-ver=1.4 cd-journal=joma no-vol=120 cd-vols= no-issue=3 article-no= start-page=307 end-page=312 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=XIV Multimodality treatment for malignant glioma kn-title=XIV 悪性神経膠腫に対する multimodality treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name=市川智継 kn-aut-sei=市川 kn-aut-mei=智継 aut-affil-num=1 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name=黒住和彦 kn-aut-sei=黒住 kn-aut-mei=和彦 aut-affil-num=2 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name=伊達勲 kn-aut-sei=伊達 kn-aut-mei=勲 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　脳神経外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　脳神経外科学 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　脳神経外科学 en-keyword=悪性神経膠腫 kn-keyword=悪性神経膠腫 en-keyword=multimodality treatment kn-keyword=multimodality treatment en-keyword=脳機能マッピング kn-keyword=脳機能マッピング en-keyword=放射線治療 kn-keyword=放射線治療 en-keyword=化学療法 kn-keyword=化学療法 END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=323 end-page=330 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Comprehensive Genomic Profiling for Precise Diagnosis of Pediatric-Type Diffuse High-Grade Glioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the current World Health Organization classification of central nervous system tumors, comprehensive genetic and epigenetic analyses are considered essential for precise diagnosis. A 14-year-old male patient who presented with a cerebellar tumor was initially diagnosed with glioblastoma and treated with radiation and concomitant temozolomide chemotherapy after resection. During maintenance temozolomide therapy, a new contrast-enhanced lesion developed in the bottom of the cavity formed by the resection. A second surgery was performed, but the histological findings in specimens from the second surgery were different from those of the first surgery. Although genome-wide DNA methylation profiling was conducted using frozen tissue for a precise diagnosis, the proportion of tumor cells was insufficient and only normal cerebellum was observed. We then performed comprehensive genetic analysis using formalin-fixed paraffin-embedded sections, which revealed MYCN amplification without alteration of IDH1, IDH2, or Histone H3. Finally, the patient was diagnosed with pediatric-type diffuse high-grade glioma, H3-wildtype and IDH-wildtype. In conclusion, comprehensive genetic and epigenetic analysis should be considered in pediatric brain tumor cases. en-copyright= kn-copyright= en-aut-name=MakinoKeigo en-aut-sei=Makino en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SurugaYasuki en-aut-sei=Suruga en-aut-mei=Yasuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=pediatric brain tumor kn-keyword=pediatric brain tumor en-keyword=genome-wide DNA methylation kn-keyword=genome-wide DNA methylation en-keyword=MYCN kn-keyword=MYCN END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=335 end-page=340 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of High-Grade Glioma in an Eloquent Area Treated with Awake Craniotomy in an 85-year-old Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=An 85-year-old woman presented with aphasia due to an occupying lesion in the left frontal lobe near the language area. Complete resection of the contrast-enhancing lesion was performed under awake conditions. The pathological diagnosis was anaplastic astrocytoma, and postoperative radiochemotherapy was administered. Awake surgery is a useful technique to reduce postoperative neurological sequelae and to maximize surgical resection. Although the patient was elderly, which is generally considered high risk, she did not have any severe neurological deficits and had a good outcome. Even in the extreme elderly, awake surgery can be useful for gliomas in language cortices. en-copyright= kn-copyright= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Hamamatsu University School of Medicine, University Hospital kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=awake surgery kn-keyword=awake surgery en-keyword=high-grade glioma kn-keyword=high-grade glioma en-keyword=eloquent area kn-keyword=eloquent area en-keyword=elderly patient kn-keyword=elderly patient END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=160 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gene expression profiling of the anti-glioma effect of Cilengitide en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cilengitide (EMD121974), an inhibitor of the adhesive function of integrins, demonstrated preclinical efficacy against malignant glioma. It is speculated that cilengitide can inhibit tumor growth, invasion, and angiogenesis. However, the effects of cilengitide on these processes have not been sufficiently examined. In this study, we investigated the anti-glioma effect of cilengitide using DNA microarray analysis. U87ΔEGFR cells (human malignant glioma cell line) were used for this experiment. The cells were harvested after 16 h of cilengitide treatment, and mRNA was extracted. Gene expression and pathway analyses were performed using a DNA microarray (CodeLink?Human Whole Genome Bioarray). The expression of 265 genes was changed with cilengitide treatment. The expression of 214 genes was up-regulated by more than 4-fold and the expression of 51 genes was down-regulated by more than 4-fold compared to the controls. In pathway analysis, "apoptotic cleavage of cellular proteins" and "TNF receptor signaling pathway" were over-represented. Apoptotic-associated genes such as caspase 8 were up-regulated. Gene expression profiling revealed more detailed mechanism of the anti-glioma effect of cilengitide. Genes associated with apoptosis were over-represented following cilengitide treatment. en-copyright= kn-copyright= en-aut-name=OnishiManabu en-aut-sei=Onishi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MichiueHiroyuki en-aut-sei=Michiue en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimazuYosuke en-aut-sei=Shimazu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChioccaE Antonio en-aut-sei=Chiocca en-aut-mei=E Antonio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KaurBalveen en-aut-sei=Kaur en-aut-mei=Balveen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=9 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=10 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=Glioma kn-keyword=Glioma en-keyword=Integrin kn-keyword=Integrin en-keyword=Cilengitide kn-keyword=Cilengitide en-keyword=Gene expression profiling kn-keyword=Gene expression profiling en-keyword=Apoptosis kn-keyword=Apoptosis END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=3 article-no= start-page=259 end-page=260 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hosting the 16th Annual Meeting of the Japanese Society for Normal Pressure Hydrocephalus kn-title=第16回日本正常圧水頭症学会を岡山で開催して en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name=伊達勲 kn-aut-sei=伊達 kn-aut-mei=勲 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=128 cd-vols= no-issue=1 article-no= start-page=69 end-page=70 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hosting the 18th JASMEE Academic Meeting in Okayama kn-title=第18回日本医学英語教育学会を岡山で開催して en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name=伊達勲 kn-aut-sei=伊達 kn-aut-mei=勲 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　脳神経外科学 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low frequency of intracranial progression in advanced NSCLC patients treated with cancer immunotherapies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intracranial metastases are common in nonsmall-cell lung cancer (NSCLC) patients, whose prognosis is very poor. In addition, intracranial progression is common during systemic treatments due to the inability to penetrate central nervous system (CNS) barriers, whereas the intracranial effects of cancer immunotherapies remain unclear. We analyzed clinical data to evaluate the frequency of intracranial progression in advanced NSCLC patients treated with PD-1 blockade therapies compared with those treated without PD-1 blockade therapies, and found that the frequency of intracranial progression in advanced NSCLC patients treated with PD-1 blockade therapies was significantly lower than that in patients treated with cytotoxic chemotherapies. In murine models, intracranial rechallenged tumors after initial rejection by PD-1 blockade were suppressed. Accordingly, long-lived memory precursor effector T cells and antigen-specific T cells were increased by PD-1 blockade in intracranial lesions. However, intracranial rechallenged different tumors are not suppressed. Our results indicate that cancer immunotherapies can prevent intracranial progression, maintaining long-term effects intracranially as well as systemically. If intracranial recurrence occurs during the treatment with PD-1 blockade therapies, aggressive local therapies could be worthwhile. en-copyright= kn-copyright= en-aut-name=KemmotsuNaoya

Many studies have shown that a motif of 11 consecutive arginines (11R) is one of the most effective protein transduction domains (PTD) for introducing proteins into the cell membrane. By conjugating this "11R", all sorts of proteins can effectively and harmlessly be transferred into any kind of cell. We therefore examined the transduction efficiency of 11R in cerebral arteries and obtained results showing that 11R fused enhanced green fluorescent protein (11R-EGFP) immediately and effectively penetrated all layers of the rat basilar artery (BA), especially the tunica media. This method provides a revolutionary approach to cerebral arteries and ours is the first study to demonstrate the successful transductionof a PTD fused protein into the cerebral arteries. In this review, we present an outline of our studies and other key studies related to cerebral vasospasm and 11R, problems to be overcome, and predictions regarding future use of the 11R protein transduction method for cerebral vasospasm (CV).

Many studies using animals clarify that glial cell line-derived neurotrophic factor (GDNF) has strong neuroprotective and neurorestorative effects on dopaminergic neurons. Several pilot studies clarified the validity of continuous intraputaminal GDNF infusion to patients with Parkinson's disease (PD), although a randomized controlled trial of GDNF therapy published in 2006 resulted in negative outcomes, and controversy remains about the efficacy and safety of the treatment. For a decade, our laboratory has investigated the efficacy and the most appropriate method of GDNF administration using animals, and consequently we have obtained some solid data that correspond to the results of clinical trials. In this review, we present an outline of our studies and other key studies related to GDNF, the current state of the research, problems to be overcome, and predictions regarding the use of GDNF therapy for PD in the future.

This case gives us the essence of the occurrence mechanisms of Chiari malformation and foramen magnum decompression. en-copyright= kn-copyright= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiYasuyuki en-aut-sei=Miyoshi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=Chiari malformation kn-keyword=Chiari malformation en-keyword=dural plasty kn-keyword=dural plasty en-keyword=foramen magnum decompression kn-keyword=foramen magnum decompression en-keyword=syrinx kn-keyword=syrinx en-keyword=venous drainage kn-keyword=venous drainage END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=6 article-no= start-page=429 end-page=434 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Therapeutic Potential of Human Umbilical Cord Blood Transplantation for Neonatal Hypoxic-Ischemic Brain Injury and Ischemic Stroke en-subtitle= kn-subtitle= en-abstract= kn-abstract=Human umbilical cord blood (HUCB) cells are rich source of immature stem cells, which have the potential to repair lost tissue. Intractable central nervous system (CNS) disorders are important targets for regenerative medicine, and the application of HUCB cells is being investigated in animal models of CNS disorders. Transplantation of HUCB has induced functional improvements in these animal models due to multiple therapeutic effects including neuroprotection, anti-inflammation, angiogenesis, and neurogenesis. HUCB cells are easily available and safer than other stem cells used in transplantation therapy. In this review, we focus on HUCB transplantation as an encouraging therapeutic approach for animal models of neonatal hypoxic-ischemic brain injury and ischemic stroke. en-copyright= kn-copyright= en-aut-name=WangFeifei en-aut-sei=Wang en-aut-mei=Feifei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaNagamasa en-aut-sei=Maeda en-aut-mei=Nagamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuruEmi en-aut-sei=Tsuru en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamashitaTatsuyuki en-aut-sei=Yamashita en-aut-mei=Tatsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShenYuan en-aut-sei=Shen en-aut-mei=Yuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsudaMasayuki en-aut-sei=Tsuda en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SagaraYusuke en-aut-sei=Sagara en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Center for Innovative and Translational Medicine, Kochi Medical School affil-num=3 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Center for Innovative and Translational Medicine, Kochi Medical School affil-num=6 en-affil= kn-affil=Center for Innovative and Translational Medicine, Kochi Medical School affil-num=7 en-affil= kn-affil=Center for Innovative and Translational Medicine, Kochi Medical School affil-num=8 en-affil= kn-affil=Center for Innovative and Translational Medicine, Kochi Medical School affil-num=9 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=10 en-affil= kn-affil=Center for Innovative and Translational Medicine, Kochi Medical School en-keyword=umbilical cord blood kn-keyword=umbilical cord blood en-keyword=cell transplantation kn-keyword=cell transplantation en-keyword=neonatal hypoxic-ischemic brain injury kn-keyword=neonatal hypoxic-ischemic brain injury en-keyword=ischemic stroke kn-keyword=ischemic stroke en-keyword=stem cells kn-keyword=stem cells END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=6 article-no= start-page=487 end-page=492 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful Treatment of Epilepsy by Resection of Periventricular Nodular Heterotopia en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report on a case of successful surgical treatment of drug-resistant epilepsy associated with a solitary lesion of periventricular nodular heterotopia (PNH). In the reported patient, intracranial ictal electroencephalography disclosed that seizures did not originate from the heterotopic nodules. However, the seizures were completely suppressed by lesionectomy of PNH alone. Epileptogenesis associated with PNH likely involves a very complex network between PNH and the surrounding cortex, and the disruption of this network may be an effective means of curing intractable, PNH-associated epilepsy. en-copyright= kn-copyright= en-aut-name=AgariTakashi en-aut-sei=Agari en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiharaTadahiro en-aut-sei=Mihara en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BabaKoichi en-aut-sei=Baba en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiKatsuhiro en-aut-sei=Kobayashi en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UsuiNaotaka en-aut-sei=Usui en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeradaKiyohito en-aut-sei=Terada en-aut-mei=Kiyohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraFumihiro en-aut-sei=Nakamura en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsudaKazumi en-aut-sei=Matsuda en-aut-mei=Kazumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital affil-num=2 en-affil= kn-affil=National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders affil-num=3 en-affil= kn-affil=National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders affil-num=4 en-affil= kn-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital affil-num=5 en-affil= kn-affil=National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders affil-num=6 en-affil= kn-affil=National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders affil-num=7 en-affil= kn-affil=National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders affil-num=8 en-affil= kn-affil=National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders affil-num=9 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital en-keyword=periventricular nodular heterotopia kn-keyword=periventricular nodular heterotopia en-keyword=epilepsy kn-keyword=epilepsy en-keyword=surgery kn-keyword=surgery en-keyword=ictal electroencephalography kn-keyword=ictal electroencephalography END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue=10 article-no= start-page=3848 end-page=3856 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Combination therapy with hydrogen peroxide and irradiation promotes an abscopal effect in mouse models en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hydrogen peroxide (H2O2) induces oxidative stress and cytotoxicity, and can be used for treating cancers in combination with radiotherapy. A product comprising H2O2 and sodium hyaluronate has been developed as a radiosensitizer. However, the effects of H2O2 on antitumor immunity remain unclear. To investigate the effects of H2O2, especially the abscopal effect when combined with radiotherapy (RT), we implanted murine tumor cells simultaneously in two locations in mouse models: the hind limb and back. H2O2 mixed with sodium hyaluronate was injected intratumorally, followed by irradiation only at the hind limb lesion. No treatment was administered to the back lesion. The H2O2/RT combination significantly reduced tumor growth at the noninjected/nonirradiated site in the back lesion, whereas H2O2 or RT individually did not reduce tumor growth. Flow cytometric analyses of the tumor-draining lymph nodes in the injected/irradiated areas showed that the number of dendritic cells increased significantly with maturation in the H2O2/RT combination group. In addition, analyses of tumor-infiltrating lymphocytes showed that the number of CD8+ (cluster of differentiation 8) T cells and the frequency of IFN-γ+ (interferon gamma) CD8+ T cells were higher in the noninjected/nonirradiated tumors in the H2O2/RT group compared to those in the other groups. PD-1 (programmed death receptor 1) blockade further increased the antitumor effect against noninjected/nonirradiated tumors in the H2O2/RT group. Intratumoral injection of H2O2 combined with RT therefore induces an abscopal effect by activating antitumor immunity, which can be further enhanced by PD-1 blockade. These findings promote the development of H2O2/RT therapy combined with cancer immunotherapies, even for advanced cancers. en-copyright= kn-copyright= en-aut-name=KemmotsuNaoya en-aut-sei=Kemmotsu en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuLi en-aut-sei=Zhu en-aut-mei=Li kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FangYue en-aut-sei=Fang en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Microbial and Biochemical Pharmacy, School of Pharmacy, China Medical University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=abscopal effect kn-keyword=abscopal effect en-keyword=dendritic cell kn-keyword=dendritic cell en-keyword=hydrogen peroxide kn-keyword=hydrogen peroxide en-keyword=radiosensitizer kn-keyword=radiosensitizer en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=tumor-draining lymph node kn-keyword=tumor-draining lymph node END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=561 end-page=566 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effective Epilepsy Surgery for Post-Traumatic West Syndrome Following Abusive Head Trauma en-subtitle= kn-subtitle= en-abstract= kn-abstract=West syndrome, an infantile developmental and epileptic encephalopathy with a deleterious impact on long-term development, requires early treatment to minimize developmental abnormality; in such cases, epilepsy surgery should be considered a powerful therapeutic option.

Her seizures were suppressed by hemispherotomy at 12 months of age, leading to developmental improvement. Surgical treatment of West syndrome following traumatic brain injury has not been reported previously but is worth considering as a treatment option, depending on patient age and brain plasticity. en-copyright= kn-copyright= en-aut-name=TsuchiyaHiroki en-aut-sei=Tsuchiya en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShibataTakashi en-aut-sei=Shibata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueTakushi en-aut-sei=Inoue en-aut-mei=Takushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobayashiKatsuhiro en-aut-sei=Kobayashi en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pediatrics (Child Neurology), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics (Child Neurology), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, National Hospital Organization Okayama Medical Center kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics (Child Neurology), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics (Child Neurology), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=abusive head trauma kn-keyword=abusive head trauma en-keyword=developmental and epileptic encephalopathy kn-keyword=developmental and epileptic encephalopathy en-keyword=epilepsy surgery kn-keyword=epilepsy surgery en-keyword=epileptic spasms kn-keyword=epileptic spasms en-keyword=hemispherotomy kn-keyword=hemispherotomy END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=2 article-no= start-page=56 end-page=65 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of genome-wide DNA methylation profiling for pediatric-type diffuse gliomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite the current progress of treatment, pediatric-type diffuse glioma is one of the most lethal primary malignant tumors in the central nervous system (CNS). Since pediatric-type CNS tumors are rare disease entities and highly heterogeneous, the diagnosis is challenging. An accurate diagnosis is essential for the choice of optimal treatment, which leads to precision oncology and improvement of the patient’s outcome. Genome-wide DNA methylation profiling recently emerged as one of the most important tools for the diagnosis of CNS tumors, and the utility of this novel assay has been reported in both pediatric and adult patients. In the current World Health Organization classification published in 2021, several new entities are recognized in pediatric-type diffuse gliomas, some of which require methylation profiling. In this review, we investigated the utility of genome-wide DNA methylation profiling in pediatric-type diffuse glioma, as well as issues in clinical application of this assay. Furthermore, the combination of genome-wide DNA methylation profiling and other comprehensive genomic assays, which may improve diagnostic accuracy and detection of the actionable target, will be discussed. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatomiKaishi en-aut-sei=Satomi en-aut-mei=Kaishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SurugaYasuki en-aut-sei=Suruga en-aut-mei=Yasuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IchimuraKoichi en-aut-sei=Ichimura en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Kyorin University School of Medicine kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Brain Disease Translational Research, Graduate School of Medicine, Juntendo University kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Genome-wide DNA methylation profiling kn-keyword=Genome-wide DNA methylation profiling en-keyword=pediatric-type diffuse glioma kn-keyword=pediatric-type diffuse glioma en-keyword=pediatric brain tumor kn-keyword=pediatric brain tumor END start-ver=1.4 cd-journal=joma no-vol=133 cd-vols= no-issue=1 article-no= start-page=78 end-page=79 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hosting the 79th Annual Meeting of the Japan Neurosurgical Society in Okayama kn-title=日本脳神経外科学会第79回学術総会を岡山で開催して en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name=伊達勲 kn-aut-sei=伊達 kn-aut-mei=勲 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科　脳神経外科学 END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=3 article-no= start-page=197 end-page=202 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proximal Vertebral Body Fracture after 4-Level Fusion Using L1 as the Upper Instrumented Vertebra for Lumbar Degenerative Disease: Report of 2 Cases with Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Some cases with lumbar degenerative diseases require multi-level fusion surgeries. At our institute, 27 and 4 procedures of 3- and 4-level fusion were performed out of a total 672 posterior lumbar interfusions (PLIFs) on patients with lumbar degenerative disease from 2005 to 2010. We present 2 osteoporotic patients who developed proximal vertebral body fracture after 4-level fusion. Both cases presented with gait disability for leg pain by degenerative lumbar scoliosis and canal stenosis at the levels of L1/2-4/5. After 4-level fusion using L1 as the upper instrumented vertebra, proximal vertebral body fractures were found along with the right pedicle fractures of L1 in both cases. One of these patients, aged 82 years, was treated as an outpatient using a hard corset for 24 months, but the fractures were exacerbated over time. In the other patient, posterolateral fusion was extended from Th10 to L5. Both patients can walk alone and have been thoroughly followed up. In both cases, the fracture of the right L1 pedicle might be related to the subsequent fractures and fusion failure. In consideration of multi-level fusion, L1 should be avoided as an upper instrumented vertebra to prevent junctional kyphosis, especially in cases with osteoporosis and flat back posture. en-copyright= kn-copyright= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahashiYuichi en-aut-sei=Takahashi en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumamotoShinji en-aut-sei=Kumamoto en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaMasayuki en-aut-sei=Nakahara en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YonedaKotaro en-aut-sei=Yoneda en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NiimuraTatsuomi en-aut-sei=Niimura en-aut-mei=Tatsuomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanoueTakashi en-aut-sei=Tanoue en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KusumegiAkira en-aut-sei=Kusumegi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SennariTakashi en-aut-sei=Sennari en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HijikataYasukazu en-aut-sei=Hijikata en-aut-mei=Yasukazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ManabeHiroaki en-aut-sei=Manabe en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyoshiYasuyuki en-aut-sei=Miyoshi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OgawaKoichi en-aut-sei=Ogawa en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NishidaKenki en-aut-sei=Nishida en-aut-mei=Kenki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=2 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=3 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=4 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=5 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=6 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=7 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=8 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=9 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=10 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=11 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Hospital affil-num=12 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Hospital affil-num=13 en-affil= kn-affil=Department of Neurological Surgery, Okayama University Hospital affil-num=14 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital affil-num=15 en-affil= kn-affil=Department of Spinal Surgery, Shinkomonji Hospital en-keyword=degenerative lumbar scoliosis kn-keyword=degenerative lumbar scoliosis en-keyword=osteoporosis kn-keyword=osteoporosis en-keyword=pedicle fracture kn-keyword=pedicle fracture en-keyword=posterior lumbar interbody fusion kn-keyword=posterior lumbar interbody fusion en-keyword=vertebral body fracture kn-keyword=vertebral body fracture END start-ver=1.4 cd-journal=joma no-vol=167 cd-vols= no-issue=1 article-no= start-page=201 end-page=210 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Midline invasion predicts poor prognosis in diffuse hemispheric glioma, H3 G34-mutant: an individual participant data review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Diffuse hemispheric glioma, H3 G34-mutant (DHGs), is a newly categorized tumor in pediatric-type diffuse high-grade gliomas, World Health Organization grade 4, with a poor prognosis. Although prognostic factors associated with genetic abnormalities have been reported, few reports have examined the clinical presentation of DHGs, especially from the viewpoint of imaging findings. In this study, we investigated the relationship between clinical factors, including imaging findings, and prognosis in patients with DHGs.
Methods We searched Medline through the PubMed database using two search terms: “G34” and “glioma”, between 1 April 2012 and 1 July 2023. We retrieved articles that described imaging findings and overall survival (OS), and added one DHG case from our institution. We defined midline invasion (MI) as invasion to the contralateral cerebrum, brainstem, corpus callosum, thalamus, and basal ganglia on magnetic resonance imaging. The primary outcome was 12-month survival, estimated using Kaplan?Meier curves and logistic regression.
Results A total of 96 patients were included in this study. The median age was 22 years, and the proportion of male patients was 48.4%. Lesions were most frequently located in the frontal lobe (52.6%). MI was positive in 39.6% of all patients. The median OS was 14.4 months. Univariate logistic regression analysis revealed that OS was significantly worse in the MI-positive group compared with the MI-negative group. Multivariate logistic regression analysis revealed that MI was an independent prognostic factor in DHGs.
Conclusions In this study, MI-positive cases had a worse prognosis compared with MI-negative cases. en-copyright= kn-copyright= en-aut-name=KegoyaYasuhito en-aut-sei=Kegoya en-aut-mei=Yasuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueYohei en-aut-sei=Inoue en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizutaRyo en-aut-sei=Mizuta en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KoizumiShinichiro en-aut-sei=Koizumi en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanakaYoshihiro en-aut-sei=Tanaka en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Hamamatsu University School of Medicine kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Hamamatsu University School of Medicine kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Division of Epidemiology, Graduate School of Public Health, Shizuoka Graduate University of Public Health kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Diffuse hemispheric gliomas, H3 G34-mutation kn-keyword=Diffuse hemispheric gliomas, H3 G34-mutation en-keyword=Midline invasion kn-keyword=Midline invasion en-keyword=Frontal lobe kn-keyword=Frontal lobe en-keyword=Gross total resection kn-keyword=Gross total resection END
