Introduction: Imbalance between the aggressive and defensive factors and presence of acidpepsin is supposed to play a major role in aetiopathogenesis of peptic ulcer disease. Recently, role of oxidative free radicals have been implicated in mediating cold-restraint stress, H.pylori, NSAID induced gastric injury. Objective: The present study was undertaken to evaluate the possible role of antiox...
The present study provides a direct experimental evidence that the combination of influenza A/ Aichi/2/68 (H3N2) infection with different models of ‘‘oxidative stress’’, such as immobilization, cold and cold-restraint, is associated with graduated oxidative disturbances in the liver of mice, despite the absence of virus and inflammation in this tissue. It was found that experimental influenza v...

three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
اجزا بدنه خودرو عموما در معرض بارهای نامتناسب قرار دارند. از آنجا که تخمین عمر اجزا سازه و بدنه خودرو عموما به تغییر وزن و شتاب خودرو و هزینه ساخت و مسائل ایمنی و استحکام و عمر سازه منتهی می گردد، در صنایع طراحی و ساخت خودرو از اهمیت ویژه ای برخوردار است. تئوری های ارائه شده در این زمینه عموما برای اجزاسازه ای تحت بارهای بسیار ابتدایی سینوسی و هندسه اولیه ارائه شده اند، به گونه ای که عمر قطعات ...

1.1 Important aspects on ulcer pathogenesis World-wide, peptic Ulcer disease (PUD) is considered as a common gastrointestinal disorder. It develops as a result of altered balance between offensive and defensive factors. Offensive (aggressive) factors disrupt normal mucosal integrity and allow H+ back diffusion with a subsequent cellular injury. Helicobacter pylori (H. pylori) and nonsteroidal a...
