the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node. The aim of this study was to determine the effects of nitric oxide (NO) on the electrophysiological properties of isolated rabbit AV node and to investigate the role of adrenergic and cholinergic receptors in the mechanism of its action...
مطالعات انجام شده روی مکانیسمهای تکوینی و تکاملی گلبولهای قرمز منجر به دستیابی بشر به مفاهیم پایه و مهمی در ارتباط با مکانیسمهای عمومی تنظیم بیان ژن وشکل گیری بافتها شده است. تمایز اختصاصی به رده ارتیروئید و هر رده دیگری، شدیداً وابسته به تنظیم در سطح بیان ژن و فاکتورهای کنترلی خاص نظیر سیتوکین ها، فاکتورهای نسخه برداری ویژه، عناصر کنترل کننده چرخه سلولی، تکثیر،آپوپتوز و عناصر سیگنالینگ داخل سلو...
Previous studies have shown that the receptive field properties, spontaneous activity and spatio-temporal interactions of low-threshold mechanical somatosensory cells in the barrel cortex are influenced by C-fibers. In this study, we examined the effect of C-fiber depletion on response properties of barrel cortex neurons following experience dependent plasticity. Methods: In this study, exte...
The aim of this study was to determine the rheological properties of sponge cake batters andphysical (volume, density, moisture content, weight after baking and color) and sensory properties of spongecake formulated with four different levels of wild sage seed gum (0, 0.5, 0.75 and 1.0 %). Sponge cake battersformulated with gums showed pseudoplastic (shear-thinning) and thixotropic (time-depend...
objective(s): the rotavirus nonstructural protein 4 (nsp4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase c-dependent and phospholipase c-independent pathways in infected cells. it is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...
nanoindentation techniques are widely used for the study of nanomechanical properties of thin nanocomposite coatings. theoretical concepts and practical use of nanoindentation method are summarized with reporting the applications of these tests in characterization of some particular thin nanocomposite hybrid coatings prepared by sol-gel process. the better mechanical properties can be obtained ...
