Neurogenic Dilator and Constrictor Responses of Pial Arteries in Vitro
Two distinct responses to transmural electrical stimulation of cerebrovascular smooth muscle isolated from dogs and sheep have been identified. Both these responses were blocked with tetrodotoiin and therefore were attributed to stimulation of intramural nerves. A constrictor response to transmural nerve stimulation (TNS) which was blocked with guanethidine was attributed to stimulation of symp...

فرهنگ های گوناگون دریافت ها و تعبیر های مختلفی از تناسب و ادب دارند. بنابراین، ارتباط میان فرهنگی خطرات ذاتی خطای ارتباطی را نشان می دهد. این پژوهش به منظور تعیین وقوع انتقال منظورشناختی زبان در زبان بینابینی زبان آموزان ایرانی، اختلاف منظورشناختی زبان را بین فارسی و انگلیسی در کنش های کلامی پاسخ تحسین و انتقاد بررسی می کند.داده ها از میان 33 آمریکایی انگلیسی زبان، 85 زبان آموز ایرانی در سطوح م...
15 صفحه اولMechanism of ATP-induced local and conducted vasomotor responses in isolated rat cerebral penetrating arterioles.
BACKGROUND Adenosine triphosphate (ATP), a potent vascular regulator in the cerebral circulation, initiates conducted vasomotor responses which may be impaired after pathological insults. We analyzed the mechanism of ATP-induced local vasomotor responses and their effect on conducted vasomotor responses in rat cerebral penetrating arterioles. METHODS Arterioles were cannulated and their inter...
متن کاملMechanism of extracellular K+-induced local and conducted responses in cerebral penetrating arterioles.
BACKGROUND AND PURPOSE Extracellular concentration of potassium ion ([K+]o) may have a significant influence on the cerebral circulation in health and disease. Mechanisms of [K+]o-induced conducted vasomotor responses in cerebral arterioles, possibly linking microvascular regulation to neuronal activity, have not been examined. METHODS We analyzed vascular responses to small increases of [K+]...
