The T-type Ca(2+) channel (TTCC) plays important roles in cellular excitability and Ca(2+) regulation. In the heart, TTCC is found in the sinoatrial nodal (SAN) and conduction cells. Cav3.1 encodes one of the three types of TTCCs. To date, there is no report regarding the regulation of Cav3.1 by β-adrenergic agonists, which is the topic of this study.(More)
BACKGROUND AND PURPOSE The endocannabinoid, anandamide, has anti-arrhythmic effects. The aim of the present study was to explore the electrophysiological effects of anandamide on rat myocardium. EXPERIMENTAL APPROACH Evoked action potentials (APs) were recorded using intracellular recording technique in rat cardiac papillary muscles. In addition, L-type(More)
This study investigated the effects of alcoholic extract of Butea superba (BS) on cognitive deficits and depression-related behavior using olfactory bulbectomized (OBX) mice and the underlying molecular mechanisms of its actions. OBX mice were treated daily with BS (100 and 300 mg/kg, p.o.) or reference drugs, tacrine (2.5 mg/kg, i.p.) and imipramine (10(More)
