Background—The reverse rate dependence (RRD) of actions of I Kr-blocking drugs to increase the action potential duration (APD) and beat-to-beat variability of repolarization (BVR) of APD is proarrhythmic. We determined whether inhibition of endogenous, physiological late Na ϩ current (late I Na) attenuates the RRD and proarrhythmic effect of I Kr inhibition.
Hepatoprotective agents could prevent tissue damage and reduce morbidity and mortality rates; such agents may include folkloric or alternative treatments. The present study evaluated the protective effects of the flavonoid-rich fraction from rhizomes of Smilax glabra Roxb. (SGF) on carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. Sprague-Dawley(More)
BACKGROUND/AIMS Resveratrol has been demonstrated to be protective in the cardiovascular system. The aim of this study was to assess the effects of resveratrol on hydrogen peroxide (H(2)O(2))-induced increase in late sodium current (I(Na.L)) which augmented the reverse Na(+)-Ca(2+) exchanger current (I(NCX)), and the diastolic intracellular Ca(2+)(More)
The objectives of this study were to investigate the inhibitory action of capsaicin on wild-type (WT) and mutation human ether-a-go-go-related gene (hERG) potassium channel currents (I(hERG)), and to determine whether mutations in the S6 region are significant for the inhibition of I(hERG) by capsaicin. The hERG channel (WT, Y652A and F656A) was expressed(More)
Zebrafish is a widely used animal model with well-characterized background in developmental biology. The fate of human adipose-derived stem cells (ADSCs) after their xenotransplantation into the developing embryos of zebrafish is unknown. Therefore, human ADSCs were firstly isolated, and then transduced with lentiviral vector system carrying a green(More)
Like other parts of the central nervous system, the adult mammalian optic nerve is difficult to regenerate after injury. Transplantation of the peripheral nerve or a Schwann cell (SC) graft can promote injured axonal regrowth. We tried to develop a new type of tissue-engineered SC graft that consisted of SCs seeded onto a poly(lactic-co-glycolic(More)
Tissue inhibitor of metalloproteinases-1 (TIMP-1) is a multifunctional matrix metalloproteinase, and it is involved in the regulation of cell proliferation and apoptosis in various cell types. However, little is known about the effect of TIMP-1 expression on the proliferation of adipose-derived stem cells (ADSCs). Therefore, TIMP-1 expression in the ADSCs(More)
