در این پژوهش منشاء خزندگان را مورد بررسی قرار داده، خانواده های سوسماران را در ایران معرفی نموده و ویژگی های آنها را ذکر کرده ایم، خانواده lacertidae را از منظر فیلوژنی، رده بندی و همچنین جنس های آن را، مرور کرده ایم. جنس lacerta که هدف اصلی پژوهش حاضر است در ایران دارای دو گونه می باشد؛ یکی گونه ی lantz & cyrén, 1920 lacerta media که از این گونه، تنها زیرگونه ی lacerta media media lantz & cy...
Ten to 15% of couples are infertile, with the most common causes being linked to the production of few or no oocytes or sperm. Yet, our understanding of human germ cell development is poor, at least in part due to the inaccessibility of early stages to genetic and developmental studies. Embryonic stem cells (ESCs) provide an in vitro system to study oocyte development and potentially treat fema...
AIM The present study was carried out to evaluate the effect of supplementation of β-mercaptoethanol (β-ME) on in vitro maturation rate and glutathione (GSH) level of buffalo oocytes. MATERIALS AND METHODS Oocytes were recovered from buffalo's ovaries collected from government approved slaughter house (near Kamela darwaza, Surat) of Surat Municipal Corporation. The obtained oocytes were in vi...
the notion of baer modules was defined recently
background: the expanse of dendritic cells (dc) differentiation plays an important role in determining immune response. dc-based immunosuppressive drugs have notable side effects in increasing the risk of infectious diseases and cancers. g2013, as a novel anti-inflammatory and immunosuppressive agent, has been tested in experimental model of multiple sclerosis. the aim of this study was to cond...
BACKGROUND Oocyte maturation and subsequent in vitro production (IVP) of embryos are affected by diverse groups of chemicals in maturation medium which are needed for successful mammalian oocyte maturation during which the dramatic cytoplasmic and nuclear reprogramming events take place. This study was designed to evaluate the effects of protein source (fetal bovine serum, FBS, and bovine serum...
In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author's experience. In IVM cycles,...
The nutritional requirements of mammalian embryos changes throughout pre-implantation period, coincident with changes in the secretion of the female reproductive tract. Therefore, it has been suggested that sequential culture media may support nutritional requirements for optimal growth of the mammalian embryos. In this study, we investigated the effect of two different concentrations (10 or 10...
The maturation of oocytes is one of the most important steps determining their developmental competence. Due to the low percentage of oocytes of bitches that reach the MII stage, searching for reagents that may stimulate the growth and maturation of oocytes is still present in this species of mammals. The most important media supplements include gonadotropins (LH, FSH, hCG), growth factors (IGF...
