Background: Vitrification of oocyte is one of the most important topics in the field of assisted reproductive techniques (ART). Considering the importance of oocyte vitrification in clinics, in the present study the effect of vitrification on mouse oocytes survivale rate and apoptosis by cryotop were investigated. Materials and Methods: 200 GV oocytes and 200 MII oocytes were obtained respectiv...

Background and aims: Various culture media along with some supplements and enrichment materials have been suggested for in vitro maturation. This study aims to investigate the effect of retinoic acid on nuclear maturation of immature mouse oocytes in vitro. Materials and methods: immature oocytes were obtained from 6-8 weeks old NMRI mice, 48 hours after intraperitoneal injection of 7.5 units ...

In this paper an extensive study of the concepts generalized Green’s relations and GV -semigroups without order to ordered semigroups have been given. Our approach allows one see nature in class -ordered semigroups. Moreover we show that semigroup S is a if only complete semilattice completely π-regular Archimedean

Background: The effects of cumulus cells and the effectiveness of a PDE3 specific inhibitor (Cilostamide) in comparison with an adenylate cyclase activator (Forskolin) on the maturation rate and developmental competence of mouse germinal vesicle (GV) oocytes were evaluated Materials and Methods: Germinal vesicles (GV) oocytes of PMSG-primed mice were divided into cumulus denuded oocytes (CDOs) ...

Glycemic variability (GV) has been proposed as contributor to diabetes-related macrovascular complications. This randomized control trial evaluated a new combination therapy with continuous subcutaneous insulin infusion (CSII) plus sitagliptin (CSII + sitagliptin) vs. CSII only in terms of metabolic control, GV and β-cell function in patients with newly diagnosed type 2 diabetes (T2DM). 217 pat...

In mammalian cells, 5-methylcytosine (5-meC) can be transformed into 5-hydroxymethylcytosine (5-hmC) by the methylcytosine dioxygenase TET proteins (TET1, TET2 and TET3). Thymine DNA glycosylase (TDG), a downstream enzyme of TET proteins, not only functions in base excision repair, but also acts as a key enzyme that participates in active DNA demethylation. Here we microinjected exogenous TDG-m...

OBJECTIVE To evaluate the impact of graft size on recipients in living donor liver transplantation (LDLT) to establish a clinical guideline for the minimum requirement. SUMMARY BACKGROUND DATA Although the minimum graft size required for LDLT has been reported to be 30% to 40% of graft volume (GV)/standard liver volume (SLV), the safety limit of the graft size was unknown. METHODS A total o...

Glycemic variability (GV) is reportedly a predictor for poor outcome in various clinical conditions. We aimed to assess whether GV during hospital admission is associated with poor outcomes in patients with acute ischemic stroke (AIS) and diabetes. We prospectively enrolled consecutive patients with AIS from the registry of 6 tertiary hospitals between January 2013 and December 2014. For the GV...

BACKGROUND AND OBJECTIVE Transient activation of the hypothalamic-pituitary-gonadal axis with a sex steroid surge is observed in boys and girls during the first months of life. However, the role of sex steroids in the regulation of growth has not been substantiated in infancy. We tested the hypothesis that testosterone (T) surge, known to be higher in infant boys than in girls during the transi...

There is a wide and rich scientific literature about Gender Violence (GV) in diverse institutions contexts, now including Isolating (IGV). However, there an almost absolute silence GV IGV within the field of critical pedagogy despite its pretention to influence children’s education. This paper part long research program on presents first evidence existence pedagogy. The communicative methodolog...
