Optical mapping of repolarization and refractoriness from intact hearts.
BACKGROUND Heterogeneities of repolarization (R) across the myocardium have been invoked to explain most reentrant arrhythmias. The measurement of refractory periods (RPs) has been widely used to assess R, but conventional electrode and extrastimulus mapping techniques have not provided reliable maps of RPs. METHODS AND RESULTS Guinea pig hearts were stained with a voltage-sensitive dye to me...
متن کاملIntact Rabbit Hearts
The intracellular events and specifically the role of protein kinase C-mediated protein phosphorylation, after a-adrenergic receptor stimulation of the heart, are not well understood. We examined the phosphorylation of sarcolemmal, sarcoplasmic reticular, myofibrillar, and cytosolic proteins in perfused beating rabbit hearts on activation of protein kinase C by phenylephrine. Perfusion of rabbi...
متن کاملRealtime Cardiac Surgery Simulation
This thesis is an investigation of the possibilities of realtime surgical simulation, specifically within the domain of congenital heart diseases. The problem domain of surgery on the heart of an infant is presented and the primary information necessary for a pre-operative surgical simulation tool is identified. Through cooperation with surgeons, domain specific abstractions and simplifications...
متن کاملBisphenol A Exposure and Cardiac Electrical Conduction in Excised Rat Hearts
BACKGROUND Bisphenol A (BPA) is used to produce polycarbonate plastics and epoxy resins that are widely used in everyday products, such as food and beverage containers, toys, and medical devices. Human biomonitoring studies have suggested that a large proportion of the population may be exposed to BPA. Recent epidemiological studies have reported correlations between increased urinary BPA conce...
متن کاملmanipulation in dubbing and subtitling
پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
