A series of sequential experiments were carried out to determine optimum diluents, cryoprotectants, equilibration time, and thawing temperature for frozen duck semen in order to set up the commercial semen cryopreservating techniques which could be applied to the conservation of genetic resources, breeding, and commercial production in domestic ducks. In experiment 1, the seven semen extenders ...

RZT is potent anti migraine drug having agonist activity at the 5-hydroxytryptamine (5-HT) 1B and 5-HT 1D receptor. It commonly used for relief of headaches in treatment of migraine. Conventional tablets of RZT are not capable of rapid action, which is required for immediate relief from migraine pain. Marketed freeze dried tablet of RZT is available. Freeze drying is cumbersome and it yields a ...

Bacteriol. 89:52-57. 1965.-A study was made of the infectivity of poliovirus ribonucleic acid (RNA), applied in various diluents, and of poliovirus, on cell monolayers which were washed free from their nutrient medium and all...

By using experimentally infected rabbits as a model for early syphilis, the applicability of in vitro DNA amplification was explored for detection of Treponema pallidum. It was determined that whole blood in heparin or EDTA (but not serum), lesion exudate, and punch biopsy as well as swabs of lesions are useful specimens for examination by the polymerase chain reaction. Swabs do not require spe...
