(silicone elastomer, Dow Corning Corporation, U.S.A) which had window of some 3×3 mm in the center. The Sylgard block was turned over and then placed at the bot- tom of the chamber, so that the preparation faced a glass coverslip. The distribution of ICC-MY was determined by constructing z-stacks from the myenteric region where net- works of c-Kit positive cell were apparent in guinea-pig... The properties of voltage dependent Ca2＋ current (VDCC) were investigated in interstitial cells of Cajal (ICC) distributed in the myenteric layer (ICC-MY) of guinea-pig antrum. In tissue, ICC-MY showed c-Kit positive reactions and produced driving potentials with the amplitude and frequency of about 62 mV and 2 times min−1, respectively, in the presence of 1</SUP>ՌM nifedipine. Single ICC-MY isolated by enzyme treatment also showed c-Kit immunohistochemical reactivity. These... -

to silicone elastomer layered in a dissecting Petri dish. The adhering ventricular myo cardium and connectve tssue were carefully removed under binocular examination. The arteries were then incubated for 30 min at room temperature in the same medium， except that ca1cium was omitted. Enzymatic dispersion was then initiated by incubating the artery for 3040 min with collagenase (2.5 mgjml，... It has been proposed that Ca2-activated K (KCa) channels play an essential role in vascular tone. The alterations of the properties of coronary KCa channels have not been studied as a possible mechanism for impaired coronary reserve in cardiac hypertrophy. The present studies were carried out to determine the properties of coronary KCa channels in normal and hypertrophied hearts. These channels were measured from rabbit coronary smooth muscle cells using a patch clamp technique.... -

a portion of myocardium attached to it and was then pinned down to silicone elastomer layered in a dis secting Petri dish. The adhering ventricular myocar dium and connectve tissue were carefully removed under binocular examination. The arteries were then incubated for 30 min at room temperature in the same medium， except that calcium was omitted. Enzymatic dispersion was then initiated by... The aim of present study was to define the cellular mechanisms underlying changes in delayed rectifier K (KDR) channel function in isoproterenol-induced hypertrophy. It has been proposed that KDR channels play a role in regulation of vascular tone by limiting membrane depolarization in arterial smooth muscle cells. The alterations of the properties of coronary KDR channels have not been studied as a possible mechanism for impaired coronary reserve in cardiac hypertrophy. The present... -

[25] Tanaka S, Chao Y, Araki S,... In this study, in order to improve the thermal and electrical properties of epoxy/graphene nanoplatelets (GNPs), surface modifications of GNPs are conducted using silane coupling agents. Three silane coupling agents, i.e. 2-(3,4-epoxycyclohexyl)-ethyltrimethoxysilane (ETMOS), 3-glycidoxypropyltriethoxysilane (GPTS), and 3-glycidoxypropyltrimethoxysilane (GPTMS), were used. Among theses, GPTMS exhibits the best modification performance for fabricating GNP-incorporated epoxy composites. The effect... -

천연고무와 실리콘고무에 자기장응답형 분말을(Magnetic Responsible Powder; MRP) 배합하여 자기장응답형 엘라스토머(Magneto-rheological Elastomer; MRE)를 제조하였다. MRP의 최적 사용량은 30 vol.% 였으며 천연고무 기반 MRE의 기계적 물성은 실리콘고무 기반 MRE 보다 우수했지만, magneto-rheological (MR) 효과는 실리콘고무 기반 MRE가 더욱 우수하였다. MR 효과는 Self-modified Electromagnet Applied Fast Fourier Transform Analyser (SEFFTA)를 사용하여 측정되었는데 천연고무 기반 MRE의 경우는 10%, 실리콘고무 기반... -
