rate of in vitro maturation of oocytes is one of the challenges of assisted reproductive techniques. in this study we investigated the effects of supplementation of cysteamine on the rate of in vitro maturation of oocytes in two different media. germinal vesicle oocytes were collected from mouse ovary and cultured in two media (tcm199 and meme) with 0, 50, 100, 200, 500 µm/ml cysteamine. number...
background: dominant lactic acid bacteria (lab) originally isolated from traditional non-dairy fermented foods, may harbor unique characteristics such as probiotic properties. in this research, probiotic potential of dominant lab isolated from pickled garlic was studied. methods: after isolation of dominant lab from pickled garlic produced with apple cider vinegar, the isolate was identified by...
introduction: spreading depression (sd) is a propagating wave of depolarization followed by depression of the neuroglial activities and can modulate extracellular dopamine concentrations in the neocortex. it has been shown that the dopaminergic system plays a role in migraine. sd has been suggested as a critical phenomenon in the pathophysiology of migraine. the aim of this study was to investi...
background: endometrial secretion analysis is a non-invasive and promising method in evaluation of endometrial receptivity. objective: the aim of the present study was to assess the relationship between the success rate of ivf procedures and some endometrial secretion cytokines, including interleukin-1β (il-1β), tumor necrosis factor (tnf-α), interferon gamma-induced protein 10 (ip-10), and mon...
Objective: The purpose of the current study was to investigate the in vivo (analgesic, antidiarrheal, neurological, and cytotoxic) and in vitro (antioxidant, antimicrobial, thrombolytic and anthelmintic) activity of different fractions of methanolic extract of Momordica charantia. Materials and Methods: The antioxidant property ...
Background: This study intends to present the role of rescue in vitro maturation (IVM) in polycystic ovarian syndrome(PCOS) patients undergoing in vitro fertilization (IVF) treatment who have inappropriate responses to ovarianstimulation.Materials and Methods: This was a retrospective case series study of five PCOS patients undergoing IVF treatmentconsidered for cycle ca...
چکیده: گیاه عدس الملک با نام علمی securigera securidacaاز تیره نخودیان یکی از گیاهان دارویی است که پراکندگی رشد این گیاه در سطح جهان در اروپا، آسیا و استرالیا و در ایران در استان تهران و اطراف آن، استان خوزستان فارس و کهگیلویه و بویر احمد است. بذر گیاه عدس المک بطور گسترده ای در طب سنتی ایران و هند برای کنترل قند خون افراد دیابتی استفاده می شده است. در تحقیقات اخیر آثار ضد هرپس ویروسی نوع 1 بذ...
عنوان:ساخت سازه مهندسی جهت بیان انسولین درشرایط in vitro مقدمه: دیابت بیماری است که در جهان شیوع بسیاری دارد، از این رو تلاش های مستمری جهت درمان بیماری با روش های مختلف صورت گرفته است . ژن درمانی به دلیل پایداری بهتر نسبت به سایر روش ها اهمیت زیادی دردرمان دیابت بویژه دیابت نوع iپیدا کرده است. وجود یک روش درمانی ایمن و کارآمد همواره مد نظر محققین بوده که با وجود تلاش های فراوان تاکنون این امر...
OBJECTIVE To compare the outcomes of embryo development between oval-shaped oocyte as an abnormal morphology oocyte and a normal morphology oocyte in In Vitro Fertilization (IVF). METHODS This study was a comparative analytical study with retrospective approach which lasted from September 2014 until November 2015. For this study, we used secondary data (medical records) from 24 patients submi...
Chemical circuits can coordinate elaborate sequences of events in cells and tissues, from the self-assembly of biological complexes to the sequence of embryonic development. However, autonomously directing the timing of events in synthetic systems using chemical signals remains challenging. Here we demonstrate that a simple synthetic DNA strand-displacement circuit can release target sequences ...
