Berberine prolongs the duration of cardiac action potentials without affecting resting membrane potential or action potential amplitude. Controversy exists regarding whether berberine exerts this action by preferential block of different components of the delayed rectifying potassium current, I(Kr) and I(Ks). Here we have studied the effects of berberine on(More)
Since the establishment of the brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) in North America and Europe, there has been a large, multi-group effort to characterize the composition and impact of the indigenous community of arthropod natural enemies attacking this invasive pest. In this review, we combine 98 indigenous(More)
Effects of membrane potential, intracellular Ca2+ and adenine nucleotides on glucose-sensitive channels from X organ (XO) neurons of the crayfish were studied in excised inside-out patches. Glucose-sensitive channels were selective to K+ ions; the unitary conductance was 112 pS in symmetrical K+, and the K+ permeability (PK) was 1.3 × 10-13 cm · s-1. An(More)
The survival of rat postnatal mesencephalic dopamine (DA) neurons in dissociated cell cultures was studied by examining the combinatorial effects of dibutyryl cyclic adenosine monophosphate (db-cAMP), glial cell line-derived neurotrophic factor (GDNF), and brain-derived neurotrophic factor (BDNF), as well as selective inhibitors of protein kinase A (PKA),(More)
Lara, Jesús, Juan José Acevedo, and Carlos G. Onetti. Largeconductance Ca-activated potassium channels in secretory neurons. J. Neurophysiol. 82: 1317–1325, 1999. Large-conductance Caactivated K channels (BK) are believed to underlie interburst intervals and contribute to the control of hormone release in several secretory cells. In crustacean(More)
