Objective: Indomethacin is a non-selective cyclooxygenase (COX) inhibitor that is commonly administered to extremely low gestational age neonates for symptomatic patent ductus arteriosus. It suppresses prostaglandins which modulate growth and secretion of various hormones. We examined the hypothesis that early postnatal administration of Indomethacin may influence growth and development of test...

Background: Therapeutic utilities of doxorubicin (DOX), an anticancer anthracycline antibiotic, are limited by its serious dosedependent toxicity to non-target tissues such as testis. The aim of the present study was to elucidate the potential of simvastatin (SIM), a lipid lowering agent with antioxidant and anti-inflammatory activities, to attenuate DOX-induced spermatotoxicity in male mice. M...

Background In fertility studies, it has been shown that transforming growth factor β (TGFβ) and interlukin 10 (IL-10) play very important roles in implantation, maternal immune tolerance, placentation and fetal development, and the release beginning of release for fetal and postnatal death. The present study aims to determine the effects of the postmating administration of neutralizing antibodi...

introduction: embryonic stem (es) cells are pluripotent cells derived from the inner cell mass of blastocysts. these cells are appropriate for creation of animal models of human genetic diseases, the study of gene functions in vivo and differentiation into specific types as potential therapeutic agents for several diseases. we describe here production of transgenic chimeric mouse blastocysts by...

introduction: the plethora of studies indicated that there is a cross talk relationship between harmaline and serotonergic (5-ht) system on cognitive and non-cognitive behaviors. thus, the purpose of this study is to assess the effects of hippocampal 5-ht4 receptor on memory acquisition deficit induced by harmaline.  methods: harmaline was injected peritoneally, while 5-ht4 receptor agonist (rs...

background: although cervical cancer mortality has reduced during last years, but it is still leading cause of mortality among women. many efforts have performed to develop new drugs and strategy to cure cervical cancer. mesenchymal stem cells (mscs) have many advantages that make them a suitable choice as a cell therapeutic agent in cancer treatment. there are different transfection methods fo...

objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...
