Zinc has been considered as a vital constituent of proteins, including enzymes. Mobile reactive zinc (Zn2+) is the key form of zinc involved in signal transductions, which are mainly driven by its binding to proteins or the release of zinc from proteins, possibly via a redox switch. There has been growing evidence of zinc’s critical role in cell signaling, due to its flexible coordination geometry and rapid shifts in protein conformation to perform biological reactions. The importance and... -
Potassium Currents in Isolated Deiters' Cells of Guinea Pig

a class III anti-arrhythmic K+ channel blocker. The remaining outward current was transient in time course whereas the clofilium-sensitive outward current showed slow inactivation and delayed rectification. Addition of 5 mM tetraethylammonium (TEA) further blocked the remaining current leaving a very fast inactivating transient outward current. Therefore, at least three different types of K+ current were identified in Deiters' cells, such as fast activating and fast inactivating current, fast... -
Study on urea precursor effect on the electroactivities of nitrogen-doped graphene nanosheets electrodes for lithium cells
Ki-Yong Kim, Yongju Jung, Seok Kim 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 5 40-46 (7 pages)
Nitrogen-atom doped graphene oxide was considered to prevent the dissolution of polysulfide and to guarantee the enhanced redox reaction of sulfur for good cycle performance of lithium sulfur cells. In this study, we used urea as a nitrogen source due to its low cost and easy preparation. To find the optimum urea content, we tested three different ratios of urea to graphene oxide. The morphology of the composites was examined by field emission scanning electron microscope. Functional groups and... -

많은 강과 하천에서 하나의 대표적인 유량이 안정하도 형태를 결정하는데 사용되어 질 수 있다. 이러한 대표적인 하도형성유량은 여러 연구자들의 접근 방식의 차이에 따라 강턱유량, 특정 재현기간유량, 유효유량 등으로 표시된다. 따라서 본 연구에서는 대상유역의 특성인자와 관측자료를 이용하여 하도형성유량을 산정하고, 강턱유량과 수리기하 특성간의 상관관계를 분석하였다. 문막과 서면 수위관측소에서 하도형성유량으로 결정된 강턱유량의 재현기간은 유출량 자료를 빈도분석한 결과, 문막은 1.8년, 서면은 1.5년으로... -

Kanagawa hemolysin (KH), an exotoxin produced from Kanagawa phenomenon-positive Vibrio parahemolyticus, has been shown to possess various biological activities including hemolysis, enterotoxicity, cytotoxicity, and cardiotoxicity. The aim of this study was to investigate the effect of KH on the cardiovascular system and its mechanism, employing in vivo and in vitro experiments of the rat. Intracerebroventricular (icv) administration of 100 mHU KH produced a marked and continuous pressor effect...
