Background: Several methods for sex selection of embryos have been used in research centers and infertility centers till now. Materials and Methods: In this research, the effect of medium, by placing the mouse (NMRI) spermatozoa in the medium containing certain concentrations of albumin and ascorbic acid, separation of spermatozoa containing X and Y chromosomes and doing in vitro fertilization ...

Introduction: The origin of neonatal oocyte development is unknown. However, estrogen plays an essential role during development of the female reproductive system. Anastrozole is used as both ovulation stimulating and an anticancer drug. The aim of this study was to evaluate the impact of Anastrozole on follicular development and differentiation in mice. Materials and methods: In the present s...

Effect of excessive ingestion of manganese (Mn) on the mouse thyroid was assessed under the conditions of normal intake of iodide. Female mouse thyroids were enlarged after 7 weeks of administration of 200 mg/l MnCl2 X 4H2O in drinking water; 2.74 +/- 0.25 mg for control (N = 56), and 3.31 +/- 0.28 mg for Mn-treated group (N = 85) (p less than 0.001). In contrast, male mouse thyroids never beca...

conclusions it seem that melatonin due to its antioxidant properties, if added to glycerol based media, reduces the harmful effects of freezing-thawing process, and protects seminiferous tubules histological structure from oxidative injury. results the result showed that supplementation of glycerol based media with melatonin has reduced injury to histological structure of seminiferous tubules i...

Most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. The general use of NMRI outbred mice is a model for toxicology, teratology and pharmacology. NMRI mouse embryo exhibit the two-cell block in vitro. The objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...

These experiments examined the effects of pre-test intra dorsal hippocampus (intra-CA1) administration of GABAA receptor agonist and antagonist, muscimol and bicuculline respectively, on state-dependent learning induced by lithium. Male NMRI mice were trained in a one-trial step-down inhibitory avoidance task, and immediately after training they received IP injections of either saline (10 mL/kg...

Rett syndrome (RTT) is a severe X-linked neurodevelopmental disorder that primarily caused by mutations in the methyl CpG binding protein 2 gene (MECP2). RTT second most prevalent genetic cause of intellectual disability girls, and there currently no cure for disease. We have previously shown therapy using self-complementary AAV9 viral vector expressing codon-optimized Mecp2 version (AAV9-MCO) ...
