More VEGF, more life—and health span Advanced aging is celebrated but its ill effects, deterioration at the cell, tissue, and organ levels, are not. Grunewald et al . provide evidence for vascular theory of aging, which reports that age-related decrease function a driver organismal large (see Perspective by Augustin Kipnis). Vascular endothelial growth factor (VEGF) signaling insufficiency unde...
مقدمه و هدف : یکی از عوامل مهم و تاثیرگذارجهت دستیابی به انطباق بدون تنش در پروتزهای متکی بر ایمپلنت، انجام قالبگیری دقیق می باشد. دو روش قالبگیری مستقیم و غیرمستقیم برای انتقال موقعیت ایمپلنت از دهان به کست کار وجود دارد. هدف از انجام این مطالعه بررسی دقت وسایل رایج جهت قالبگیری به روش غیرمستقیم درسه نوع سیستم مختلف ایمپلنت دندانی و مقایسه آنها با روش مستقیم می باشد. مواد و روش ها : در...
introduction: the objective of this study was to evaluated effect of retinoic acid (ra) on the tibia osteogenesis in the chick embryos. materials and methods: for this purpose 0.75mg ra dissolved in 2ml dimthylsulfoxide (dmso) was droped on the limb bud of chick embryos at sixth day of incubation. the osteogenesis of tibia in ra-treated embryos were compared with normal control and dmso-treated...
A growing body of evidence supports the existence of a tissue-based renin-angiotensin system (RAS) in the vasculature, but the functional capacity of vascular RAS was not investigated in humans. In 28 normotensive healthy control subjects, the metabolism of angiotensins through vascular tissue was investigated in normal, low, and high sodium diets by the measurement of arterial-venous gradient ...
Purpose: To present a patient with interaconal orbital angioleiomyoma. Case Report: A 22-year-old woman presented with painless slowly progressive proptosis. CT and MRI demonstrated a well-defined Interaconal globe size mass (inferomedially). It was isointense in T1 and T2 weighted and homogenously enhanced by Gadolinium. During the surgery, the tumor was excised via a lateral orbitotomy approa...
Tissue factor pathway inhibitor (TFPI) is a potent regulator of tissue factor - factor VII-dependent activation of the tissue factor pathway. TFPI is a serine protease inhibitor that contains three Kunitz domains and a basic carboxyl terminus. TFPI is primarily expressed on endothelial cells, and murine models have demonstrated that its expression regulates vascular thrombosis. The localization...
Background & Aims: Human amniotic membrane has some specific properties making it an appropriate biomaterial for using in vascular tissue engineering. In this study, amniotic membrane was preserved with different methods. Effects of preservation on amniotic extracellular matrix and adhesion of cultured endothelial cells to membrane were compared with fresh samples of amniotic membrane. Mate...
Training of microvascular anastomosis techniques comprise the major part of surgical skills, necessary for revascularization surgeries. Training can be performed in several stages based on the experience of trainees. This should mainly start with various models of artificial materials that simulate tissues. In the next stage, trainee should practice microsurgical skill on a non-living tissue mo...
