In CA1 pyramidal neurons in rat hippocampal tissue slices, superfusion with ischemia-simulating medium produced a rapid depolarization after 6 min of exposure. The membrane potential eventually reached 0 after 5 min (a persistent depolarization), even when oxygen and glucose were reintroduced. The role of various ions in the reversal of this persistent depolarization after reintroduction of oxy...
The authors used the PatchXpress 7000A system to measure compound activity at the hERG channel using procedures that mimicked the "gold-standard" conventional whole-cell patch clamp. A set of 70 compounds, including hERG antagonists with potencies spanning 3 orders of magnitude, were tested on hERG302-HEK cells using protocols aimed at either identifying compound activity at a single concentrat...
Prophylactic drug therapy is a major component of overall migraine management. However, because we do not know how currently used prophylactic drugs exert their beneficial effects in migraine, their use is based primarily on clinical trials. In general, prophylactic drugs are indicated when patients have three or more attacks a month and symptomatic medication use alone is not satisfactory. The...
1. gamma-Aminobutyric acid (GABA) withdrawal syndrome (GWS) represents a particular model of focal epilepsy consecutive to the interruption of a chronic intracortical GABA infusion and is characterized by the appearance of focal epileptic electroencephalographic (EEG) discharges and localized clinical signs on withdrawal of GABA. Effects of Ca2+ channel blockers and N-methyl-D-aspartate (NMDA) ...
It is known that catalepsy serves as an experimental animal model of parkinsonism. In this study, the relationship between in vivo dopamine D1 and D2 receptor occupancies and catalepsy was investigated to predict the intensity of catalepsy induced by drugs that bind to D1 and D2 receptors nonselectively. 3H-SCH23390 and 3H-raclopride were used for the labeling of D1 and D2 receptors, respective...
