PURPOSE Multiple small case series have reported sperm in the ejaculate and spontaneous pregnancies in patients with nonobstructive azoospermia after varicocele repair. We hypothesized that men with favorable testicular histopathology on testis biopsy such as maturation arrest or hypospermatogenesis would have a higher probability of success than those with more ablative pathology, eg Sertoli-c...
Regulation of tone, blood pressure, and blood flow in the cerebral vasculature is of vital importance, particularly in the developing infant. We tested the hypothesis that, in addition to accretion of smooth muscle cells (SMCs) in cell layers with vessel thickening, significant changes in smooth muscle structure, as well as phenotype, extracellular matrix, and membrane proteins, in the media of...
This work was undertaken in order to examine M-phase promoting factor (MPF) and mitogen-activated protein kinases (MAPK) activities during meiotic progression of cat oocytes cultured in two different media for two different incubation times and preovulatory cat oocytes that reached MII in vivo. Oocytes recovered from ovaries of ovariectomized cats were cultured either in TCM 199 or SOF for 24 h...
In this study, a dose-response assessment was performed to understand the relation between supplementation of media with L-ascorbic acid or vitamin C and porcine oocyte maturation and the in vitro development of parthenotes (PA) and handmade cloned (HMC) embryos. Various concentrations (0, 25, 50 and 100 μg/ml) of vitamin C supplemented in in vitro maturation (IVM) and culture (IVC) media were ...
