background: there are few studies indicating the detrimental effects of ibuprofen on sperm fertility potential and dna integrity. objective: to determine the effects of ibuprofen on sperm parameters, chromatin condensation and dna integrity of mice. materials and methods: in this experimental study, 36 adult male mice with average weight 37 gr were divided into three groups, including control (...

Background: Implantation is proceeded by a process referred as adhesion. Adhesion requires maturation of endometrium and blastocyst to confer adherence ability to them. During IVF cycles, endometrial maturation is facilitated by progesterone administrating. Considering vasodilatory effect of Sildenafild, in genital organs, it appears that Sildenafil may have similar effect as progestrone. The a...

We evaluated the adoptive transfer of DCs on Leishmania (L.) mexicana-infected neonatal BALB/c mice. DCs were isolated and purified from the spleens of the following donor groups: a) Adult BALB/c mice infected during adulthood with L. (L) mexicana; b) Adult BALB/c mice infected during neonatal life; c) Healthy neonatal BALB/c mice; d) Healthy adult BALB/c mice. A neonatal model of infection, ge...

There are significant differences in the rate of neuronal death after peripheral nerve injury between species. The rate of neuronal death of motor neurons after nerve injury in the adult rats is very low, whereas that in adult mice is relatively high. However, the understanding of the mechanism underlying axotomy-induced motor neuron death in adult mice is limited. Cathepsin B (CB), a typical c...

Renal function was studied in mice of different ages. In metabolic cage experiments, the renal electrolyte excretion was similar in young (n = 8; 5- to 7-wk-old) and adult (n = 6; 20- to 22-wk-old) CD-1 (ICR) BR mice, whereas spontaneous drinking volume and urinary flow rate were significantly higher in the adult compared with the young mice. Subsequently, the renal functional reserve was inves...

Introduction:Suboptimalmanagementof postoperativepain leads to increased riskof chronicopioid therapy, especially in elderly patients. Objectives: Although this age-dependent phenomenon has been observed clinically, basic mechanisms including baseline nociception, postoperative hypersensitivity, and mu-opioid efficiency in aged animals have never been evaluated. Methods:We tested these criteria...

Bilateral common carotid artery stenosis (BCAS) models the effects of compromised cerebral blood flow on brain structure and function in mice. We compared the effects of BCAS in aged (21 month) and young adult (3 month) female mice, anticipating a differentially more severe effect in the older mice. Four weeks after surgery there was a significant age by time by treatment interaction on the rad...

Background: Phenol is an estrogenic and toxic compound and people are widely exposed to it, in different ways.  OBJECTIVES: The aim of this study was to determine  the  negative effects of phenol on the fertility of male mice, by investigating sperm parameters including viability, motility, fertility rates and daily sperm production (DSP). METHODS: A total of 106 adult NIH mice were divided int...

Abstract The study reveals the prevalence of a potential rodent-borne zoonotic helminth species, Hymenolepis diminuta in commensal rodents caught from irrigated and rain-fed areas Swat, Pakistan. Three hundred fifty (269 rats 81 mice) trapped during vegetative, flowering/fruiting mature/harvesting stages crops were studied 2011-2013. Hymenolepisdiminuta eggs identified on basis their shape, siz...

introduction: busulfan as a chemotherapeutic agent causes testicular germinal epithelium depletion and cytotoxicity in germ cells. the aim of this study was to assess antioxidant status, reactive oxygen species (ros) generation and apoptosis-related genetic markers of adult male mouse sperm following busulfan treatment. materials and methods: forty adult nmri mice (30 ± 5 g) were divided into t...
