Effect of alpha-cypermethrin and theta-cypermethrin on delayed rectifier potassium currents in rat hippocampal neurons.

Cypermethrin is a photostable synthetic pyrethroid and the most widely used Type II pyrethroid pesticide. The effects of two different stereoisomers of cypermethrin insecticides, alpha-cypermethrin and theta-cypermethrin, on the delayed rectifier potassium current (IK) in hippocampal neurons of rat, were studied using whole-cell patch clamp technique. Alpha-cypermethrin and theta-cypermethrin d...

Integrative Physiology Estrogen Contributes to Gender Differences in Mouse Ventricular Repolarization

Rationale: Fast-transient outward K (Ito,f) and ultrarapid delayed rectifier K currents (IK,slow, also known as IKur) contribute to mouse cardiac repolarization. Gender studies on these currents have reported conflicting results. Objective: Key missing information in these studies is the estral stage of the animals. We revisited gender-related differences in K currents, taking into consideratio...

hospholipase C-mediated inhibition of the M-potassium current by uscarinic-receptor activation in the vestibular primary-afferent eurons of the rat

The activation of the efferent vestibular systemmodifies the basal discharge and the dynamic response of primary-afferent neurons to headmotion and gravitational stimuli. The efferent input to afferent neurons is mediated primarily by cholinergic synapses that activate both muscarinic and nicotinic receptors. Previously we had shown that themuscarinic-acetylcholine-receptor (mAChR) activationmo...

Investigation of the Stability via Shadowing Property

The shadowing property is to find an exact solution to an iterated map that remains close to an approximate solution. In this article, using shadowing property, we show the stability of the following equation in normed group: 4n−2Cn/2−1rf ∑n j 1 xj/r n ∑ ik∈{0,1}, ∑n k 1 ik n/2 r2f ∑n i 1 −1 ik xi/r 4n·n−2Cn/2−1 ∑n i 1 f xi , where n ≥ 2, r ∈ R r2 / n and f is a mapping. And we prove that the e...
