We studied the safety and clinical outcomes of switching from DAPT to aspirin monotherapy at 3 months after ZES implantation. We retrospectively evaluated 168 consecutive patients with coronary artery disease who had been implanted with a ZES from June 2009 through March 2010. After excluding 40 patients according to exclusion criteria such as myocardial infarction, 128 patients were divided into a 3-month DAPT group (67 patients, 88 lesions) and a 12-month conventional DAPT group (61 patients, 81 lesions). Coronary angiographic followup and clinical followup were conducted at more than 8 months and at 12 months after ZES implantation, respectively. Minor and major bleeding events, stent thrombosis (ST), and major adverse cardiac events (MACE) (death, myocardial infarction, cerebrovascular accident, target lesion revascularization, and target vessel revascularization) were evaluated. There were no statistically significant differences in the incidences of ST and MACE between the two groups. The incidence of bleeding events was significantly lower in the 3-month group than in the 12-month group (1.5% versus 11.5%, ). DAPT can be safely discontinued at 3 months after ZES implantation, which reduces bleeding risk. en-copyright= kn-copyright= en-aut-name=WadaTadashi en-aut-sei=Wada en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakahamaMakoto en-aut-sei=Nakahama en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaHironobu en-aut-sei=Toda en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeAtsuyuki en-aut-sei=Watanabe en-aut-mei=Atsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HashimotoKatsushi en-aut-sei=Hashimoto en-aut-mei=Katsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TerasakaRitsuko en-aut-sei=Terasaka en-aut-mei=Ritsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaNobuyuki en-aut-sei=Yamada en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=2 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=3 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=4 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=5 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=6 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=7 en-affil= kn-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of Cardiology, Fukuyama City Hospital affil-num=9 en-affil= kn-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences END start-ver=1.4 cd-journal=joma no-vol=2012 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=2012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Theoretical Study on the Detection of Tilted Lipid Bilayers Using Surface Plasmon Resonance Techniques en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective refractive indices detected using surface plasmon resonance techniques are calculated as a function of the tilt angle of lipid bilayers in a multilayered model. The changes in the effective refractive indices are derived from the shift of an excitation angle of surface plasmon. To obtain effective refractive index plots, we determined refractive index changes in the lipid bilayers with 3 and 5?nm thicknesses as a function of tilt angle and obtained a relationship between the effective refractive index and tilt angle. We also showed that the effective refractive index depended on the lipid bilayers thickness and anisotropic permittivities, which vary with interchain distance. en-copyright= kn-copyright= en-aut-name=WatanabeKoyo en-aut-sei=Watanabe en-aut-mei=Koyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraKoji en-aut-sei=Matsuura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Research Core for Interdisciplinary Sciences, Okayama University affil-num=2 en-affil= kn-affil=Research Core for Interdisciplinary Sciences, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2012 cd-vols= no-issue= article-no= start-page=11 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Activation of Biodefense System by Low-Dose Irradiation or Radon Inhalation and Its Applicable Possibility for Treatment of Diabetes and Hepatopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Adequate oxygen stress induced by low-dose irradiation activates biodefense system, such as induction of the synthesis of superoxide dismutase (SOD) and glutathione peroxidase. We studied the possibility for alleviation of oxidative damage, such as diabetes and nonalcoholic liver disease. Results show that low-dose ƒÁ-irradiation increases SOD activity and protects against alloxan diabetes. Prior or post-low-dose X- or ƒÁ-irradiation increases antioxidative functions in livers and inhibits ferric nitrilotriacetate and carbon tetrachloride-induced (CCl4) hepatopathy. Moreover, radon inhalation also inhibits CCl4-induced hepatopathy. It is highly possible that low-dose irradiation including radon inhalation activates the biodefence systems and, therefore, contributes to preventing or reducing reactive oxygen species-related diabetes and nonalcoholic liver disease, which are thought to involve peroxidation. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University END
