Background Nonyl phenol (NP) has been considered an endocrine disrupting substance causing reproductive dysfunction and increase in reactive oxygen species production in different organs including testis. vitamin E (VitE) is a potent scavenger of free radicals and is able to prevent the membrane damage mediated by free radicals The aim of this study was to elucidate the protective effects of Vi...

Background & Aims: Neurogenesis in the adult mammal brain occurs throughout life. Adult neurogenesis has been clearly demonstrated in the sub granular zone (SGZ) of the dentate gyrus (DG) in the hippocampus. Pheromones that plays an essential role in the development of the central nervous system. The male pheromones are involved in regulating neurogenesis in both the olfactory bulb and hippocam...

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...

Objective(s): We sought to explore whether neuregulin-1(NRG1) would have a protective effect on the auditory cortices of adult C57BL/6J mice.Materials and Methods: We used RTPCR and Western blot (WB) to detect the expression of NRG1 and ERBB4 (the receptor of NRG1) in the auditory cortices of C57BL/6J mice of different ages (6–8 weeks an...

Background: One of the major factors affecting on male infertility is oxidative stress (OS). Two main sources of ROS production are leukocytes and spermatozoa. The ROS such as tertiary-butyl hydroperoxide (TBHP) may damage and fragmentate to sperm DNA, which can lead to complications in the offspring. In this study, we will investigate the effect of od on DNA fragmentation index (DFI) in sperm ...

Background: Ceftriaxone is a third-generation Cephaloporin antibiotic. It has broad spectrum activity against gram-positive and gram-negative bacteria. There are some reports about its adverse effects on sperm quality and quantity but there is a need for more investigations so we did it. Materials and Methods: 40 adult male mice were divided into 3 groups as followings: a control group, high do...

the transcriptional factor sox2 regulates the expression of some of the developmental genes, which are essential for the maintenance of pluripotency of stem cells. sox2 also expresses in the female gamete during folliculogenesis, but its role remains ambiguous. the aim of this study was to investigate the expression of sox2 in the mice ovarian tissue during different stage of estrous cycle. adu...

background and aims: this study examined sub-chronic effects of methamphetamine (meth) on the stereological parameters in the cornu ammonis (ca) of the hippocampus in adult mice. materials and methods: fifteen adult male mice, eight weeks old, were randomly divided into three groups: receive saline (controls), or low-dose (ld) 2.5 mg/kg meth, or high-dose (hd) 25 mg/kg meth, via daily intraperi...

Background: Prescription of the atypical antipsychotic drugs like as Sulpiride for the treatment of schizophrenic patients was increased because of their less side effects. This study was aimed to evaluate the effect of sulpiride on hormonal milieu of adult male mice namely their serum level of prolactin and sexual hormones. Materials and Methods: 24 adult male mice were divided in three groups...
