: In vitro three-dimensional (3D) cartilage regeneration is a promising strategy for repair of cartilage defects. However, inferior mechanical strength and tissue homogeneity greatly restricted its clinical translation. Simulation of mechanical stress through a bioreactor is an important approach for improving in vitro cartilage regeneration. The current study developed a hydrostatic pressure (...
فرآیند نورد تجمعی (accumulative roll bonding (arb)) یکی از رایج ترین روش ها برای تولید مواد ورقه ای فوق ریزدانه شده می باشد. این روش شامل چرخه های مختلفی از نورد، برش و پشته سازی است و تا مرز امکان می تواند تکرار شود. در این تحقیق، کامپوزیت چندلایه al/steel با استفاده از ورق های 1100al- و 12st- به روش arb و تا سه چرخه تولید شد. میکروساختار و خواص مکانیکی کامپوزیت چندلایه al/steel در چرخه های مخ...
Background: The association of HP and insulin resistance degree (IR) has not been evaluated in the diabetic patients so far. In this study, we evaluated the association between HP seropositivity and the homeostatic model assessment for insulin resistance (HOMA-IR) in diabetic patients. Methods: In this study, 211 diabetic patients admitted to the endocrinology clinic of Shahid Beheshti Hospita...
AbstractThe ability of hesperidin (HP) to form complexes with five metals; cobalt, nickel, zinc, calcium and magnesium was investigated. The complexation was studied using U.V spectroscopic titration, in methanol as well as aqueous buffer solutions (physiological conditions). Potential complexes were studied by IR and NMR spectroscopy, melting point and their solubility were also evaluated. The...

Background and purpose: Helicobacter pylori(HP) has an important role in the pathogenesis of gastritis, peptic ulcer and gastric cancer. The eradication of HP results in the prevention of the recurrence of peptic ulcer and its complications. In developed countries, the recurrence of infection is unusual and rare after the successful eradication of HP infection, however it is likely in develop...
Helicobacter pylori(HP) infection is always with active chronic gastritis, but there is no agreement on the role of HP in esophagitis. Recent articles have noted the protective role of HP in the incidence of esophagitis in patients with gastritis. The goal of the present research was to assess the relationship between HP and esophagitis incidence in patients with gastritis. This cro...
RATIONALE AND OBJECTIVES The purpose of this study was to assess the effect of unilateral common iliac vein occlusion on the capturing efficacy of the Greenfield filter in vitro. MATERIALS AND METHODS A stainless steel over-the-wire Greenfield filter was placed in the Silastic inferior vena cava module of a pulsatile circuit. Three 30-mm blood clots in sets of five were injected through the m...
هدف این تحقیق بررسی اثر روشهای مختلف گرده افشانی و کاربرد هورمون رشد جیبرلین و نفتالین استیک اسید (naa, ga3)، بر روی صفات و خصوصیات کمی وکیفی خرما رقم"کبکاب"، از ارقام مهم خرما و رقم اصلی نخلستانهای استان بوشهر می باشد. این تحقیق در شهرستان دشتستان در محل ایستگاه خرمای شهر سعدآباد- بوشهر در طی دو سال پی در پی (89-88) انجام گرفت. در این پژوهش پنج روش مختلف گرده افشانی شامل روش سنتی (em)، لگاره آ...
