Oxidative stress is associated with development and progression of cardiovascular disease. Angiotensin II produces oxidative stress and endothelial dysfunction, and its actions may be attenuated by the activity of angiotensin converting enzyme type 2 (ACE2) which converts angiotensin II to the vasoprotective peptide angiotensin (1-7). Similarly, increased oxidative stress is associated with aor...
Background: Phenylhydrazine (PHZ) is used to induce experimental anemia in animal models. On the other hand royal jelly is known as antioxidant compound. Therefore, here in present study we aimed to evaluate the protective effect of royal jelly on PHZ-induced damages in testicular tissue and compare its impact with vitamin C. Materials and Methods: Eighteen mature male mice were randomly divide...
nanotechnology researchers have identified a wide range of nanoparticle applications that may have an important role in medicine and treatment of diseases. due to lack of detailed documentation about the toxicology of zinc oxide (zno) nanoparticles, this study was aimed to evaluate the absorption of zno nanoparticles in hearts of female nmri mice. overall, 20 adult nmri female mice were studied...
Adult hippocampal neurogenesis was impaired in several Alzheimer's disease models overexpressing mutant human amyloid precursor protein (hAPP). However, the effects of wild-type hAPP on adult neurogenesis and whether the impaired adult hippocampal neurogenesis was caused by amyloid β (Aβ) or APP remained unclear. Here, we found that neurogenesis was impaired in the dentate gyrus (DG) of adult m...
Challenge of neonatal mice with an intranasal inoculation of Pneumocystis carinii results in a subclinical infection that takes 6 wk to resolve, whereas adult mice resolve a comparable challenge within 3 wk. This delayed clearance is due to a delayed inflammatory response in neonatal mice; however, the reason for this delay has been unknown. To determine whether the neonatal lung environment is...
Pulmonary hypertension occurs with prolonged exposure to chronic hypoxia in both adults and neonates. The Ca(2+)-dependent transcription factor, nuclear factor of activated T cells isoform c3 (NFATc3), has been implicated in chronic hypoxia-induced pulmonary arterial remodeling in adult mice. Therefore, we hypothesized that NFATc3 is required for chronic hypoxia-induced pulmonary hypertension i...
