P-106: Effect of Cilostamide on Meiotic Arrestof Ovine Oocytes
Background: in vitro maturation (IVM) of oocytes has increasing potential applications in assisted reproductive technology (ART), during which germinal vesicle (GV) oocytes cultured in vitro to produce mature (MII arrested) ones. Although functional, IVM oocytes have low developmental competence compared to in vivo matured oocytes; possibly because IVM comprises asynchrony between nuclear and c...
متن کاملDiscordance in diagnosis of osteoporosis using spine and femur bone densitometry: prevalence and related factors
Introduction: This study was conducted to evaluate prevalence and risk factors for diagnostic discordance for osteoporosis due to different T-scores of lumbar spine and femoral neck. Methods: In this cross sectional study demographic, anthropometric and risk factors for osteoporosis were derived from a database on 3,039 post-menopausal women who underwent bone densitometry for the first time i...
متن کاملAll-male asexuality: origin and maintenance of androgenesis in the Asian clam Corbicula.
Androgenesis is a rare form of asexual male reproduction found in disparate taxa across the Tree of Life. Phylogenetic analyses of mitochondrial genes suggest that androgenesis has arisen repeatedly in the Asian clam genus Corbicula. Two of these androgenetic species have been introduced to North America. Multiple lines of genetic evidence suggest that although nuclear recombination between the...
متن کاملThe effects of activated-omental extract on nuclear and cytoplasmic in vitro maturation of rat oocytes
Objective: The role of growth factors, including vascular endothelial growth factor of activated omentum on mitosis is clearly known, though not on all the aspects of in vitro oocyte maturation. This study was designed to assess the effect of activated-omental extract (AOE) on in vitro maturation (IVM) of rat cumulus-oocyte complexes (COCs). Materials and Methods: In this experimental study, th...
متن کاملFirst empirical evidence of naturally occurring androgenesis in vertebrates
Androgenesis among vertebrates is considered a rare phenomenon, with some cases reported so far, but linked to experiments involving gamete manipulation (artificial androgenesis). Herein, we report the first empirical evidence of the natural occurrence of spontaneous androgenesis in a vertebrate, the Squalius alburnoides allopolyploid complex. A genetically screened random sample of a natural p...
