In Experiment 1, to determine the developmental potential of buffalo oocytes of different qualities, compact cumulus-oocyte complexes (COCs) with an unexpanded cumulus mass, and with homogeneous ooplasm were classified as Grade 1 (with > or =5 layers of cumulus cells) and Grade 2 less than 4 layers of cumulus cells). Grade-3 oocytes were either without(More)
Buffalo follicular fluid was used in the IVM medium in place of serum and hormone additives for stimulating nuclear and cytoplasmic maturation of buffalo oocytes in vitro. Follicular fluid (buFF) was aspirated from visible surface follicles from buffalo ovaries. Cumulus oocyte complexes (COCs) were matured for 24 to 26 h at 38.5 degrees C, 5% CO(2) in air(More)
Water buffalo (Murrah) oocytes were collected from ovaries obtained from a local slaughterhouse. They were classified according to the character of the cumulus cells under a stereomicroscope and then cultured in 25 mM Hepes buffered tissue culture medium-199 (TCM-199) supplemented with 5% estrous water buffalo serum in an atmosphere containing 5% CO2 in air(More)
Buffalo ovaries were collected immediately after slaughter and were transported to laboratory in sterile saline at 37 degrees C. Follicular oocytes with the cumulus mass aspirated from 2 to 6 mm in diameter follicles were cultured in TCM-199 medium supplemented with 10% buffalo estrus serum (BES) in 5% CO(2) at 38.5 degrees C. After 20 to 24 h of(More)
In most developing countries, biotechnological applications relating to livestock need to be suitable for animal owners who are resource-poor small-scale operators who own little or no land and few animals. Livestock is becoming increasingly important to economic growth in developing countries and the application of biotechnology is largely dictated by(More)
Plasm progesterone and cortisol were measured in jugular blood by competitive protein-binding assay. Six cycling, estrus-synchronized Guernsey heifers were followed for four consecutive estrous cycles under two controlled temperature (18.2 C, 55% relative humidity; and 33.5 C, 55% relative humidity) conditions. Prolonged exposure to heat of Guernsey heifers(More)
Water buffalo (Murrah) oocytes were collected from ovaries obtained from the slaughter house. They were classified according to the character of the cumulus cells under a stereomicroscope, and cultured in 25 mM Hepes buffered Tissue Culture Medium-199 (TCM-199) supplemented with 5% estrous water buffalo serum in an atmosphere containing 5% CO2 in air at 39(More)
A series of 1,5-diarylpyrazoles having a substituted benzenesulfonamide moiety as pharmacophore was synthesized and evaluated for cyclooxygenase (COX-1/COX-2) inhibitory activities. Through SAR and molecular modeling, it was found that fluorine substitution on the benzenesulfonamide moiety along with an electron-donating group at the 4-position of the(More)
Capacitation of buffalo sperm was evaluated by induced acrosome reaction (AR) upon the exposure of 10 mM Ca2+. Culture of sperm for 8 hr in BO medium supplemented with 10 micrograms/ml heparin significantly (P < 0.01) increased the percentage of AR and confirmed by transmission electron microscopy. Vesiculization of outer acrosomal membrane and plasma(More)
