A mating system is an important life history for animals dealing with changing environments. Population density affects the plasticity of a and subsequently family structure animals, but its impacts on systems social structures are rarely investigated by using molecular markers in field conditions. In this study, microsatellite genetic markers, we examined changes Brandt's voles grassland Inner...
Activation of poly(ADP-ribose) polymerase (PARP) is an important factor in the pathogenesis of various cardiovascular and inflammatory diseases. Here, we report that the gender-specific inflammatory response is preferentially down-regulated by PARP in male animals. Female mice produce less tumor necrosis factor-alpha and macrophage inflammatory protein-1alpha in response to systemic inflammatio...
An animal model of experimental gastric Helicobacter pylori infection has been developed in the Z strain of Praomys (Mastomys) natalensis; this animal has been reported to develop gastric carcinoids and adenocarcinoma spontaneously. In the present study, male and female Mastomys were killed at 1, 2, 4, 8 and 16 weeks after H. pylori inoculation. Colonisation of H. pylori was maintained in the s...
Previously we have shown that ovariectomised (OVX) female sheep have reduced renal function and elevated blood pressure from 6 months of age following fetal uninephrectomy (uni-x) at 100 days of gestation (term = 150 days). In the current study we examined if in intact female sheep the onset of decline in renal function and elevation in blood pressure was prevented. Studies were performed at 1 ...
background: active immunization with gonadotropin releasing hormone conjugate (gnrh-bsa) manipulates the fertility axis and thus alters the reproductive cyclicity serum estradiol and progesterone levels. while the application of kamdhenu ark increases the efficacy of gnrh-bsa. objective: this experimental investigation is aimed to evaluate the modulatory effects on estrous cycle serum estradiol...
Modulations by dietary restriction on antioxidant enzymes and lipid peroxidation in developing mice.
The effects of dietary restriction (DR) on the activities of liver superoxide dismutase (SOD), catalase (Cat), and glutathione peroxidase (GPX) and the level of lipid peroxidation (LP) in developing mice were investigated in this study. Male and female Kunmin mice were fed a standard rodent diet ad libitum (AL), 80% of AL food intake (20% DR), or 65% of AL food intake (35% DR) for 12 or 24 wk. ...
BACKGROUND In a previous study, progesterone treatment of female monkeys immunized with live, attenuated SHIV89.6 abrogated the generally consistent protection from vaginal simian immunodeficiency virus (SIV) challenge. The mechanisms responsible for the loss of protection remain to be defined. The objective of the present study was to determine whether Depo-Provera administration alters protec...
background: mellitus diabetes (dm) is the most important metabolic diseases. the incidence of dm is prone to increase. vasculopathy, retinopathy, central and peripheral neuropathy are the most important reported side effects of dm. cognitive dysfunction following dm reported in both sexes. hippocampus is a major part of brain involving in cognitive function, its cells are able to neurogenesis, ...
OBJECTIVE To evaluate the effect of maternal diabetes on the blood pressure and kidney function of female offspring, as well as if such changes exacerbate during pregnancy. METHODS Diabetes mellitus was induced in female rats with the administration of streptozotocin in a single dose, one week before mating. During pregnancy, blood pressure was measured through plethysmography. On the 20th da...
