However, G protein coupled with Opn5m remains controversial due to variations in assay conditions and the origin of Opn5m across different reports. Here, we examined Opn5m from diverse species using an aequorin luminescence assay and G alpha-KO cell line. Beyond the commonly studied major G alpha classes, G alpha q, G alpha 11, G alpha 14, and G alpha 15 in the Gq class were individually investigated in this study, as they can drive distinct signaling pathways in addition to a canonical calcium response. UV light triggered a calcium response via all the tested Opn5m proteins in 293T cells, which was abolished by Gq-type G alpha deletion and rescued by cotransfection with mouse and medaka Gq-type G alpha proteins. Opn5m preferentially activated G alpha 14 and close relatives. Mutational analysis implicated specific regions, including alpha 3-beta 5 and alpha G-alpha 4 loops, alpha G and alpha 4 helices, and the extreme C terminus, in the preferential activation of G alpha 14 by Opn5m. FISH revealed co-expression of genes encoding Opn5m and G alpha 14 in the scleral cartilage of medaka and chicken eyes, supporting their physiological coupling. This suggests that the preferential activation of G alpha 14 by Opn5m is relevant for UV sensing in specific cell types. en-copyright= kn-copyright= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaTakahiro en-aut-sei=Yamashita en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biophysics, Graduate School of Science, Kyoto University kn-affil= affil-num=3 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=G protein kn-keyword=G protein en-keyword=G protein?coupled receptor (GPCR) kn-keyword=G protein?coupled receptor (GPCR) en-keyword=photoreceptor kn-keyword=photoreceptor en-keyword=rhodopsin kn-keyword=rhodopsin en-keyword=calcium intracellular release kn-keyword=calcium intracellular release en-keyword=protein?protein interaction kn-keyword=protein?protein interaction en-keyword=signal transduction kn-keyword=signal transduction en-keyword=nonvisual photoreception kn-keyword=nonvisual photoreception END start-ver=1.4 cd-journal=joma no-vol=299 cd-vols= no-issue=7 article-no= start-page=104839 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural insights into the action mechanisms of artificial electron acceptors in photosystem II en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) utilizes light energy to split water, and the electrons extracted from water are transferred to QB, a plastoquinone molecule bound to the D1 subunit of PSII. Many artificial electron acceptors (AEAs) with molecular structures similar to that of plastoquinone can accept electrons from PSII. However, the molecular mechanism by which AEAs act on PSII is unclear. Here, we solved the crystal structure of PSII treated with three different AEAs, 2,5-dibromo-1,4-benzoquinone, 2,6dichloro-1,4-benzoquinone, and 2-phenyl-1,4-benzoquinone, at 1.95 to 2.10 angstrom resolution. Our results show that all AEAs substitute for QB and are bound to the QB-binding site (QB site) to receive electrons, but their binding strengths are different, resulting in differences in their efficiencies to accept electrons. The acceptor 2-phenyl-1,4-benzoquinone binds most weakly to the QB site and showed the highest oxygen-evolving activity, implying a reverse relationship between the binding strength and oxygen-evolving activity. In addition, a novel quinonebinding site, designated the QD site, was discovered, which is located in the vicinity of QB site and close to QC site, a binding site reported previously. This QD site is expected to play a role as a channel or a storage site for quinones to be transported to the QB site. These results provide the structural basis for elucidating the actions of AEAs and exchange mechanism of QB in PSII and also provide information for the design of more efficient electron acceptors. en-copyright= kn-copyright= en-aut-name=KamadaShinji en-aut-sei=Kamada en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=electron transfer kn-keyword=electron transfer en-keyword=structural biology kn-keyword=structural biology en-keyword=crystal structure kn-keyword=crystal structure en-keyword=electron acceptor kn-keyword=electron acceptor END start-ver=1.4 cd-journal=joma no-vol=99 cd-vols= no-issue= article-no= start-page=107596 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A pediatric case of ureterolithiasis due to cystinuria accompanied by acute appendicitis; a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Acute abdominal pain, a chief complaint frequently seen in the emergency department, can be triggered by a vast range of conditions. Although ureterolithiasis is a less common cause in children, renal colic can be caused by calculi due to hereditary metabolic diseases among patients in those age groups.
Presentation of case: We report a 12-year-old girl with abdominal pain who was diagnosed with concurrent acute appendicitis and ureterolithiasis due to cystinuria. Acute appendicitis was successfully treated with cefmetazole, and the calculus was eliminated after adequate fluid loading.
Discussion: Synchronous acute appendicitis and ureterolithiasis is reported to be rare. Cystinuria is a hereditary metabolic stone-forming disease, and the first calculi can be detected in childhood. Increasing the solubility of cystine in the urine is required to prevent recurrent stone formation and accompanying complications. Urinalysis, ultrasound, and computed tomography coincidentally demonstrated two different acute pathological processes of ureterolithiasis and appendicitis.
Conclusion: Careful physical and laboratory examination can help clinicians find coexisting etiologies of acute abdominal pain. Ureterolithiasis can be seen in children with hereditary disorders such as cystinuria. Early diagnosis of cystinuria and close monitoring may lead to a better long-term outcome. en-copyright= kn-copyright= en-aut-name=HiraokaTomohiro en-aut-sei=Hiraoka en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraMai en-aut-sei=Kawamura en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakadaKeisuke en-aut-sei=Takada en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Pediatrics, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Pediatrics, Iwakuni Clinical Center kn-affil= en-keyword=Cystinuria kn-keyword=Cystinuria en-keyword=Ureterolithiasis kn-keyword=Ureterolithiasis en-keyword=Cystine kn-keyword=Cystine en-keyword=Acute appendicitis kn-keyword=Acute appendicitis en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=299 cd-vols= no-issue=4 article-no= start-page=104587 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ATP and its metabolite adenosine cooperatively upregulate the antigen-presenting molecules on dendritic cells leading to IFN-gamma production by T cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dendritic cells (DCs) present foreign antigens to T cells via the major histocompatibility complex (MHC), thereby inducing acquired immune responses. ATP accumulates at sites of inflammation or in tumor tissues, which triggers local inflammatory responses. However, it remains to be clarified how ATP modulates the functions of DCs. In this study, we investigated the effects of extracellular ATP on mouse bone marrow- derived dendritic cells (BMDCs) as well as the potential for subsequent T cell activation. We found that high concentrations of ATP (1 mM) upregulated the cell surface expression levels of MHC-I, MHC-II, and co-stimulatory molecules CD80 and CD86 but not those of co-inhibitory molecules PD-L1 and PD-L2 in BMDCs. Increased surface expression of MHC-I, MHC-II, CD80, and CD86 was inhibited by a pan-P2 receptor antagonist. In addition, the upregulation of MHC-I and MHC-II expression was inhibited by an adenosine P1 receptor antagonist and by inhibitors of CD39 and CD73, which metabolize ATP to adenosine. These results suggest that adenosine is required for the ATP-induced upregulation of MHC-I and MHC-II. In the mixed leukocyte reaction assay, ATP-stimulated BMDCs activated CD4 and CD8T cells and induced interferon-gamma (IFN-gamma) production by these T cells. Collectively, these results suggest that high concentrations of extracellular ATP upregulate the expression of antigenpresenting and co-stimulatory molecules but not that of coinhibitory molecules in BMDCs. Cooperative stimulation of ATP and its metabolite adenosine was required for the upregulation of MHC-I and MHC-II. These ATP-stimulated BMDCs induced the activation of IFN-gamma-producing T cells upon antigen presentation. en-copyright= kn-copyright= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiHiroka en-aut-sei=Onishi en-aut-mei=Hiroka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkadaYuki en-aut-sei=Ikada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasakiKento en-aut-sei=Masaki en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pharmacology, Division of Pathological Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=140 cd-vols= no-issue= article-no= start-page=105603 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202007 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exposure to particulate matter (PM2.5) and prevalence of diabetes mellitus in Indonesia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Recently emerging evidence suggests an association between particulate matter less than 2.5 ?m in diameter (PM2.5) exposure and diabetes risk. However, evidence from Asia is limited. Here, we evaluated the association between PM2.5 exposure and the prevalence of diabetes mellitus in one of the most populated countries in Asia, Indonesia.
Methods
We used the 2013 Indonesia Basic Health Research, which surveyed households in 487 regencies/municipalities in all 33 provinces in Indonesia (n = 647,947). We assigned individual exposure to PM2.5 using QGIS software. Multilevel logistic regression with a random intercept based on village and cubic spline analysis were used to assess the association between PM2.5 exposure and the prevalence of diabetes mellitus. We also assessed the lower exposure at which PM2.5 has potential adverse effects.
Results
We included 647,947 subjects with a mean age of 41.9 years in our study. Exposure to PM2.5 levels was associated with a 10-unit increase in PM2.5 (fully adjusted odds ratio: 1.09; 95% confidence interval: 1.05?1.14). The findings were consistent for quartile increases in PM2.5 levels and the cubic spline function. Even when we restricted to those exposed to PM2.5 concentrations of less than 10.0 ?g/m3 in accordance with the recommended guidelines for annual exposure to PM2.5 made by the World Health Organization, the association remained elevated, especially among subjects living in the urban areas. Hence, we were unable to establish a safe threshold for PM2.5 and the risk of diabetes.
Conclusions
Our findings suggest a positive association between PM2.5 exposure and prevalence of diabetes mellitus, which is possibly below the current recommended guidelines. Further studies are needed to ascertain the causal association of this finding. en-copyright= kn-copyright= en-aut-name=SuryadhiMade Ayu Hitapretiwi en-aut-sei=Suryadhi en-aut-mei=Made Ayu Hitapretiwi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuryadhiPutu Ayu Rhamani en-aut-sei=Suryadhi en-aut-mei=Putu Ayu Rhamani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbudureyimuKawuli en-aut-sei=Abudureyimu en-aut-mei=Kawuli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RumaI Made Winarsa en-aut-sei=Ruma en-aut-mei=I Made Winarsa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CalliopeAkintije Simba en-aut-sei=Calliope en-aut-mei=Akintije Simba kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WirawanDewa Nyoman en-aut-sei=Wirawan en-aut-mei=Dewa Nyoman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Public Health and Preventive Medicine, Faculty of Medicine, Udayana University kn-affil= affil-num=2 en-affil=Department of Electrical Engineering, Engineering Faculty, Bukit Jimbaran Campus, Udayana University kn-affil= affil-num=3 en-affil=Department of Human Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Biochemistry, Faculty of Medicine, Udayana University kn-affil= affil-num=5 en-affil=Department of International Health Institute of Tropical Medicine, Nagasaki University kn-affil= affil-num=6 en-affil=Department of Public Health and Preventive Medicine, Faculty of Medicine, Udayana University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Air pollution kn-keyword=Air pollution en-keyword=Environmental epidemiology kn-keyword=Environmental epidemiology en-keyword=nvironmental health kn-keyword=nvironmental health en-keyword=Particulate matter kn-keyword=Particulate matter en-keyword=Diabetes mellitus kn-keyword=Diabetes mellitus en-keyword=Indonesia kn-keyword=Indonesia END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue= article-no= start-page=129 end-page=134 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=Learning curve of kidney transplantation in a high-volume center: A Cohort study of 1466 consecutive recipients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The purpose of this study was to evaluate surgical outcomes of kidney transplantation (KTX) based on surgeon volume and surgeon experience, and to develop the learning curve model for KTX using the cumulative sum (CUSUM) analysis.
Methods
A retrospective review of 1466 consecutive recipients who underwent KTX between 2010 and 2017 was conducted. In total, 51 surgeons, including certified transplant surgeons, transplant fellows and surgical residents were involved in these procedures using a standardized protocol. Outcomes were compared based on surgeon volume (low [1?30] versus high [31?] volume) and surgeon's type (consultant surgeons, fellows or residents).
Results
Operative time (129 versus 135 min, P < 0.001) and warm ischemia time (20.9 versus 24.2 min, P < 0.001) were significantly shorter in the high-volume group, however postoperative outcomes were equal in both groups. The CUSUM analysis revealed that approximately 30 procedures were necessary to improve surgical skills. In addition, no effect of surgeon's type including consultant surgeons, fellows and residents on postoperative outcomes was found.
Conclusions
Surgical training in KTX using a standardize protocol can be accomplished with a steep learning curve without compromising perioperative outcomes under the careful selection of surgeons and procedures. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OutmaniLoubna en-aut-sei=Outmani en-aut-mei=Loubna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimenaiHendrikus J.A.N. en-aut-sei=Kimenai en-aut-mei=Hendrikus J.A.N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TerkivatanTurkan en-aut-sei=Terkivatan en-aut-mei=Turkan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TranKhe T.C. en-aut-sei=Tran en-aut-mei=Khe T.C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IjzermansJan N.M. en-aut-sei=Ijzermans en-aut-mei=Jan N.M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MinneeRobert C. en-aut-sei=Minnee en-aut-mei=Robert C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, And Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=3 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=4 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=5 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=6 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=7 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= en-keyword=Kidney transplantation kn-keyword=Kidney transplantation en-keyword=Surgeon volume kn-keyword=Surgeon volume en-keyword=Outcome kn-keyword=Outcome en-keyword=Cumulative sum analysis kn-keyword=Cumulative sum analysis en-keyword=Learning curve kn-keyword=Learning curve END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=3 article-no= start-page=899 end-page=905 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The distance between the tibial tunnel aperture and meniscal root attachment is correlated with meniscal healing status following transtibial pullout repair for medial meniscus posterior root tear en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
To investigate the relationship between tibial tunnel aperture location and postoperative meniscal healing.
Methods
We enrolled 25 patients (20 women and five men, mean age: 62.5 years) who underwent transtibial pullout repair for medial meniscus (MM) posterior root repair. The expected MM posterior root attachment center (AC) and tibial tunnel center (TC) were identified using three-dimensional computed tomography, and the minimum AC?TC distance was calculated. The meniscal healing status following transtibial pullout repair was assessed by second-look arthroscopy (mean postoperative period: 15 months) using a previously reported scoring system (meniscal healing score; range: 0?10). The association between AC?TC distance and meniscal healing score was investigated using univariate linear regression models. The optimal AC?TC distance cut-off for improved MM healing score (? 7) was determined using receiver operating characteristic analysis.
Results
The AC?TC distance and meniscal healing score were significantly associated (y = ? 0.42x + 9.48, R2 = 0.342; P = 0.002), with the optimum AC?TC distance being 5.8 mm. This cut-off had a sensitivity of 100% and specificity of 53%.
Conclusions
This study demonstrates that AC?TC distance is significantly correlated with postoperative meniscal healing. Anatomical repair within 5.8 mm of the AC may result in improved meniscal healing. en-copyright= kn-copyright= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyazawaShinichi en-aut-sei=Miyazawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYoshiki en-aut-sei=Okazaki en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasudaShin en-aut-sei=Masuda en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kochi Health Science Center kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Medial meniscus posterior root tear kn-keyword=Medial meniscus posterior root tear en-keyword=Pullout repair kn-keyword=Pullout repair en-keyword=Tibial tunnel kn-keyword=Tibial tunnel en-keyword=Meniscal healing kn-keyword=Meniscal healing END start-ver=1.4 cd-journal=joma no-vol=324 cd-vols= no-issue= article-no= start-page=109085 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Xylitol acts as an anticancer monosaccharide to induce selective cancer death via regulation of the glutathione level en-subtitle= kn-subtitle= en-abstract= kn-abstract=Herbal medicines and their bioactive compounds are increasingly being recognized as useful drugs for cancer treatments. The parasitic fungus Cordyceps militaris is an attractive anticancer herbal since it shows very powerful anticancer activity due to its phytocompound cordycepin. We previously discovered and reported that a high amount of xylitol is present in Cordyceps militaris extract, and that xylitol unexpectedly showed anticancer activity in a cancer-selective manner. We thus hypothesized that xylitol could become a useful supplement to help prevent various cancers, if we can clarify the specific machinery by which xylitol induces cancer cell death. It is also unclear whether xylitol acts on cancer suppression in vivo as well as in vitro. Here we show for the first time that induction of the glutathione-degrading enzyme CHAC1 is the main cause of xylitol-induced apoptotic cell death in cancer cells. The induction of CHAC1 is required for the endoplasmic reticulum (ER) stress that is triggered by xylitol in cancer cells, and is linked to a second induction of oxidative stress in the treated cells, and eventually leads to apoptotic cell death. Our in vivo approach also demonstrated that an intravenous injection of xylitol had a tumor-suppressing effect in mice, to which the xylitol-triggered ER stress also greatly contributed. We also observed that xylitol efficiently sensitized cancer cells to chemotherapeutic drugs. Based on our findings, a chemotherapeutic strategy combined with xylitol might improve the outcomes of patients facing cancer. en-copyright= kn-copyright= en-aut-name=TomonobuNahoko en-aut-sei=Tomonobu en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KomalasariNi Luh Gede Yoni en-aut-sei=Komalasari en-aut-mei=Ni Luh Gede Yoni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SumardikaI Wayan en-aut-sei=Sumardika en-aut-mei=I Wayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangFan en-aut-sei=Jiang en-aut-mei=Fan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChenYouyi en-aut-sei=Chen en-aut-mei=Youyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoKen-ichi en-aut-sei=Yamamoto en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinoshitaRie en-aut-sei=Kinoshita en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MurataHitoshi en-aut-sei=Murata en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InoueYusuke en-aut-sei=Inoue en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Faculty of Science and Technology, Division of Molecular Science, Gunma University kn-affil= affil-num=10 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Xylitol kn-keyword=Xylitol en-keyword=Cancer kn-keyword=Cancer en-keyword=Glutathione kn-keyword=Glutathione en-keyword=ER stress kn-keyword=ER stress en-keyword=Chemotherapy kn-keyword=Chemotherapy END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue= article-no= start-page=205 end-page=208 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three-year-old traumatic liver injury patient treated successfully using transcatheter arterial embolization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Liver injury is the most vulnerable to blunt abdominal trauma. Diagnostic evaluation and treatment of blunt liver trauma in children have changed essentially over the last decades.
Presentation of case
A 3-year-old girl, weighing 10 kg was run over by a car and admitted to our hospital.@Due to the liver injury and increased intra-abdominal hemorrhage confirmed by computed tomography, emergent transcatheter arterial embolization (TAE) was performed. Hemostasis was successfully obtained without complications. The patient had a good postoperative course and was discharged on the 9th day after admission.
Discussion
To the best of our knowledge, this case is the youngest and lowest weight emergency TAE success cases of childhood liver injury. TAE is an alternative to laparotomy and a useful procedure to accomplish nonsurgical management in adult who are hemodynamically stable and have no other associated injury requiring laparotomy. On the other hand, TAE is considered to have some complications in child cases because of the small diameter of the artery and the tendency to spasm. Our case showed that TAE can be a safe option for emergency hemostasis in pediatric trauma cases weighing 10 kg.
Conclusion
Emergency physicians must be aware that radiological intervention is an important adjunct to management of childhood liver injury. en-copyright= kn-copyright= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KemmotsuMasaichi en-aut-sei=Kemmotsu en-aut-mei=Masaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiiHiroaki en-aut-sei=Ishii en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Critical Care Medical Center, Okayama Red Cross Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Okayama Red Cross Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Okayama Red Cross Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama Red Cross Hospital kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Hepatic injury kn-keyword=Hepatic injury en-keyword=Non-operative management kn-keyword=Non-operative management en-keyword=Transarterial embolization kn-keyword=Transarterial embolization en-keyword=Pediatric kn-keyword=Pediatric en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=224 cd-vols= no-issue=1 article-no= start-page=411 end-page=422 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Automorphism groups of rational surfaces en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we consider automorphism groups of rational surfaces which admit cuspidal anticanonical curves and have certain nontrivial automorphisms.

Although osteoid osteomas have traditionally been treated by surgical excision, radiofrequency ablation (RFA) has gained favor as a less invasive procedure. However, RFA is contraindicated for osteoid osteomas close to the skin or crucial neurovascular structures, and is not covered by national health insurance in Japan. The aim of the present study was to evaluate the efficacy of surgical excision of osteoid osteomas using intraoperative navigation.
Methods
We performed a retrospective review of five patients with osteoid osteoma who underwent a mini-open excision using O-arm/Stealth navigation at our institution. The osteoid osteomas were excised using a cannulated cutter or curetted out with the assistance of navigation.
Results
Complete excision was achieved in all patients, which was confirmed by pathological examination. The mean skin incision was 2.1 cm (range, 1.5 to 3.0 cm) and the mean duration required for setup three-dimensional image was 15 min (range, 12 to 20 min). Although the mean visual analog scale score was 7 (range, 4 to 8) before surgery, all patients experienced relief from their characteristic pain immediately after surgery, with the mean scores of 2.2 (range, 1 to 3) and 0 at 2 days and 4 weeks after surgery, respectively. There was no intra-operative complication related to the navigation and no recurrence was observed during the mean follow-up period of 25 months (range, 13 to 33 months).
Conclusions
Mini-open excision using intraoperative O-arm/Stealth navigation is a safe and accurate procedure for patients with osteoid osteoma, which could cover the limitation of RFA. en-copyright= kn-copyright= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KunisadaToshiyuki en-aut-sei=Kunisada en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakedaKen en-aut-sei=Takeda en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MochizukiYusuke en-aut-sei=Mochizuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KiyonoMasahiro en-aut-sei=Kiyono en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END
