Leptin, the 16-kDa product of the obese (ob) gene, primarily secreted from adipose tissue, has been implicated to play an important role in the regulation of food intake and energy expenditure. This study investigated protective effect of leptin on trichostatin A-induced apoptotic on in vitro maturation ratio of buffalo oocytes. Ovaries were collected from abattoir and were transported immediat...
Effect of sodium nitroprusside (SNP), a nitric oxide (NO) donor, on in vitro survival, growth, steroidogenesis, and apoptosis of buffalo preantral follicles (PFs) was investigated. PFs (200~250 µm) were isolated by micro-dissection and cultured in 0 (control), 10(-3), 10(-5), 10(-7), and 10(-9) M SNP. To examine the reversible effect of SNP, PFs were cultured with 10(-5) M SNP + 1 mM N(ω)-nitro...
BACKGROUND Water buffalo and goats are natural hosts for S. japonicum in endemic areas of China. The susceptibility of these two hosts to schistosome infection is different, as water buffalo are less conducive to S. japonicum growth and development. To identify genes that may affect schistosome development and survival, we compared gene expression profiles of schistosomes derived from these two...
Follicle and oocyte growth is under the control of systemic gonadotropins and various local intraovarian factors. The present study was undertaken to examine the efficacy of peptide(s) isolated from ovine follicular fluid on preantral and antral follicles, oocytes, cumulus and granulosa cells, and oviductal epithelial cell growth in vitro in a heterologous species (Bubalus bubalis). Follicular ...
Studies were conducted to examine the effect of substitution of serum with cystic follicular fluid in the IVM media and also to test the efficacy of cystic follicular fluid (buCFF) at 50 and 100 per cent levels for in vitro maturation of buffalo oocytes. Resutts indicated that buffalo cystic follicular fluid supplemented with PMSG possess the ability for induction of maturation of buffalo oocyt...
The objective of this study was to investigate the effect photoperiod and other environmental factors on population Water buffalo oocytes in Veracruz, Mexico. Oocytes (n=123) were obtained by follicular aspiration graded according morphological characteristics. Data regarding regional (temperature, humidity, daylight) collected from a historic database metrological station. Statistical analysis...
Background: The objectives of a series of studies undertaken was to improve farm animal reproductive efficiency in terms of embryo production efficiency, conception rate and litter size by immunoneutralization of inhibin in conjunction with other conventional reproductive techniques. Materials and Methods: A recombinant porcine inhibin alpha-subunit mature peptide was produced by mass scale and...
Buffalo holds the unique potentiality among the livestock sector at tropical and subtropical area. The faster multiplication of superior genotypes and the conservation of endangered buffalo breeds are the important issue. Recent advances in assisted reproductive technologies (ART), including estrus/ovulation synchronization, multiple ovulation and embryo transfer (MOET), in vitro embryo product...
