The purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and DNA damage). Semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. Five healthy buffalo bulls (5 ejaculates from ...

the aim of this research was the collection and freezing of honey bee sperm, apis mellifera, as a trail and evaluating different semen extenders to improve sperm quality after freeze-thawing process as a first trail in iran. semen was collected using artificial insemination device. in this experiment three different extenders including; egg yolk (tey), buffer and 0.5% soybean lecithin (tsl0.5) ...
The purpose of this study was to investigate the efficiency of the water test to evaluate the functional membrane integrity of ejaculated canine sperm after collecting, cooling, and freezing-thawing. Twenty-five ejaculates were obtained from 12 stud dogs by digital manipulation. Sperm-rich fractions were evaluated, diluted, cooled at 5oC and frozen-thawed. A conventional hypo-osmotic swelling t...
experiment was conducted to evaluate the effect of l-glutamine on coated sperm freezing by using four rams. semen was collected by artificial vagina contact with a tube containing tris-fructose-egg yolk 15%. samples were pooled and centrifuged. after removing supernatant and diluting pellet, samples were split into 5 equal part and added 0, 40, 80, 120 and 160 mm l-glutamine. samples were froze...
The aim of this study was to determine the effect of gamma-oryzanol-enriched -rice bran oil on the quality of cryopreserved boar semen. Ten boars provided semen of proven motility and morphology for this study. The semen was divided into three portions in which lactose-egg yolk (LEY) extender used to resuspend the centrifuged sperm pellet was supplemented with 2 types of rice bran oils, at a ga...

The aim of this study was to assess two models of sperm collection on the quality and fertility of thawed spermatozoa from Black Manchega rams, a threatened breed. Sperm samples were collected by electroejaculation and postmortem from each male. Samples were diluted with Biladyl and frozen. Motility (subjective and objective by means of computer-assisted semen analysis), membrane integrity, and...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
