Objective(s) The possible risks of radio-frequency electromagnetic fields (EMF) for the living organisms and human body are a growing concern for our society. In this study, we examined the possibility of changes in working memory and hippocampal histological characteristics effects in mice brain following whole body exposure to microwave radiation. Materials and Methods During gestation per...
Effects of pregnancy and mating age on rate (gain/day) and efficiency (gain/feed) of lean and fat deposition were determined in the M 16 line of mice selected for rapid postweaning weight gain. Correlated responses in M16 mice included increased lean and fat gain and efficiency. Exclusive of their litters, M 16 females had greater (P<.01) lean tissue growth and efficiency during pregnancy than ...
The effect of pregnancy on postweaning mammary gland involution was investigated in mice. On the third day after forced weaning at Lactation Day 10, the apoptotic index was 56% lower in mammary tissue of mice that were pregnant at the time of weaning than in nonpregnant mice. Conversely, the bromodeoxyuridine-labeling index was increased sevenfold in pregnant mice compared to nonpregnant contro...

disodium glycyrrhetinic acid hemiphthalaic (gap) was evaluated for developmental toxicity in pregnant nmri mice. gap was administered intrapcritoneally on days s, 9, 10, of gestation at doses of 0, 25, 50 and 75 mg/kg/dav. on gestation day of is, after operational delivery, the fetuses were examined for soft tissue, external and skeletal defects. increased absorptions, dead fetuses, and reduce ...
BACKGROUND Pregnant women infected by the pandemic influenza A (H1N1) 2009 virus had more severe disease and higher mortality but its pathogenesis is still unclear. PRINCIPAL FINDINGS We showed that higher mortality, more severe pneumonitis, higher pulmonary viral load, lower peripheral blood T lymphocytes and antibody responses, higher levels of proinflammatory cytokines and chemokines, and ...
Relaxin and estrogen reduced the resistance to dilatation of the mouse cervical canal. Relaxin was stored in, and secreted from , the ovaries of pregnant mice. The corpus luteum of gravid women just at delivery contained 25-50 GPU/g of relaxin, while the placenta, amniotic fluid and serum had no relaxin activity. Luteinizing hormone, luteotropic hormone and oxytocin effected elongation of the i...
Maternal immune responses can promote allergy development in offspring, as shown in a model of increased susceptibility to asthma in babies of ovalbumin (OVA)-sensitized and -challenged mother mice. We investigated whether inflammatory responses to air pollution particles (diesel exhaust particles, DEP) or control "inert" titanium dioxide (TiO(2)) particles are enhanced during pregnancy and whe...
Maternal obesity is linked with increased adverse pregnancy outcomes for both mother and child. The metabolic impact of excessive fat within the context of pregnancy is not fully understood. We used a mouse model of high fat (HF) feeding to induce maternal obesity to identify adipose tissue-mediated mechanisms driving metabolic dysfunction in pregnant and non-pregnant obese mice. As expected, c...
