هدف از پژوهش حاضر بررسی تأثیر شدت تمرین ورزشی بر ساختار و عملکرد بطن چپ در رتهای مبتلا به MI بود. به این منظور، ابتدا رتهای نر نژاد ویستار تحت عمل جراحی بستن شریان LAD قرار گرفتند و سپس توسط اکوکاردیوگرافی ایجاد MI تأیید شد. چهار هفته پس از جراحی، رتهای مبتلا به MI بهصورت تصادفی در گروههای تمرین ورزشی با شدتهای کم (LIT)، متوسط (MIT)، بالا (HIT) و شم (Sham) به اضافه گروه کنترل سالم (Con)...
horacic endovascular aortic repair (TEVAR) has become aneurysms were included and the extent of aortic coverage or Testablished as a less invasive option for the management of descending thoracic aortic diseases compared with conventional open surgical repair. TEVAR has reduced morbidity and mortality compared with open surgical repair, but still it is associated with a significant risk of spin...
in this paper, a model of an optimal control problem with chance constraints is introduced. the parametersof the constraints are fuzzy, random or fuzzy random variables. todefuzzify the constraints, we consider possibility levels. bychance-constrained programming the chance constraints are converted to crisp constraints which are neither fuzzy nor stochastic and then the resulting classical op...
The intestinal ecosystem is formed by a complex, yet highly characteristic microbial community. The parameters defining whether this community permits invasion of a new bacterial species are unclear. In particular, inhibition of enteropathogen infection by the gut microbiota ( = colonization resistance) is poorly understood. To analyze the mechanisms of microbiota-mediated protection from Salmo...
this study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. one-cell mouse embryos were obtained from nmrimice after superovulation by an intraperitoneal injection of 5 iu equine chorionic gonadotrophin (ecg)followed 48 hrs later by 5 iu human chorionic gonadotrophin (hcg). mouse embryonic fibrobla...
