Background: Exercise has positive and negative effects on immune system. Herein, we would like to investigate the effects of incremental aerobic training and fish oil supplementation on the plasma levels of CRP, CPK and IL-17 in trained mice. One of the major roles of immune system is to produce soluble or cellular components that provide the immunity against inflammatory agent. The purpo...

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...

OBJECTIVE Castration of male apolipoprotein E-deficient (apoE-/-) mice reduces angiotensin II (Ang II)-induced abdominal aorta aneurysms (AAAs) to that of female mice. The purpose of this study was to determine whether this reduction is attributable to androgen-mediated regulation of aortic Ang II type 1A receptors (AT1aR). METHODS AND RESULTS AT1aR mRNA abundance in the AAA-prone region of a...

Background: Sperm DNA damage (SDD) is a significant male infertility factor, yet it is not routinely diagnosed or treated in couples undertaking fertility treatment by ART. Men with this condition are likely to experience sub-fertility or infertility, expose their female partners to greater risk of miscarriage and pass on de novo sporadic DNA mutations potentially compromising the health of the...

20-Hydroxy-5,8,11,14-eicosatetraenoic acid (20-HETE) has been linked to pro-hypertensive and anti-hypertensive actions through its ability to promote vasoconstriction and inhibit Na transport in the ascending limb of the loop of Henle, respectively. In this study, we assessed the effects of 20-HETE blockade on blood pressure, renal hemodynamics, and urinary sodium excretion in Cyp4a14(-/-) male...

objective: vanillosmopsis arborea baker (asteraceae) has high economic value from chapada to araripe and its bark essential oil is a potential source of alpha-bisabolol. the present study aimed to elucidate the antinociceptive and antipruritic properties of the essential oil of v. arborea baker (eova) in mice. materials and methods: the antinociceptive activity was assessed using the capsaicin,...

Toll-like receptor (TLR)-dependent pathways control the activation of various immune cells and the production of cytokines and chemokines that are important in innate immune control of viruses, including mouse cytomegalovirus (MCMV). Here we report that upon MCMV infection wild-type and TLR7(-/-) male mice were more resistant than their female counterparts, while TLR9(-/-) male and female mice ...

Previously, we found that male JYD mice developed type 2 diabetes but female mice did not, and that decreased expression levels of caveolin-1 were correlated with the development of a diabetic phenotype in these mice. Therefore, we hypothesized that sex hormones affect the expression of caveolin-1 and contribute to the development of insulin resistance and hyperglycemia in JYD mice. We used glu...

Repeated administration of nicotine causes incentive and behavioral sensitization in animals. Ascorbic acid administration inhibits some effects of nicotine. In the present study, the effect of ascorbic acid administration on nicotine-induced behavioral sensitization in Male Swiss-Webster mice (20-25 g) was investigated. Animals were injected with nicotine (0.25 mg/kg, i.p.) once daily for seve...
