Background: Low density lipoprotein (LDL) of egg yolk has been successfully used for stallion and bull semen cryopreservation. However, there is limited information to clarify the effect of LDL or lyophilized LDL on ram semen quality. On the other hand, during semen collection, dilution and cryopreservation we need to protect the spermatozoa from lipid peroxidation. Clove bud has polyphenolic c...

An extender is defined to be an active manipulator worn by a human to increase his strength [6]. The human, in physical contact with the extender, exchanges power and information signals with the extender. The human arm, the extender, and the environment comprise the dynamic model of the extender system. In this paper, an expression for system performance is derived to determine the force augme...

Animal origin egg yolk extender has been associated with microbial contamination and interference with microscopic examination. Therefore, replacement of such extender with plant origin compound is inevitable without compromising the desired qualities of an ideal extender. In the current experiment, we compared the effect of soy-based extender (25% and 50%) of five adult Holstein-Friesian bulls...

the aim of this study was to evaluate the effect of bovine serum albomin (bsa) in stallion semen extender in cool condition. after collection, semen samples were pooled and divided into four equal parts. each part was diluted with one of the following extenders: 1) extender without bsa (bsa-0), 2) extender containing 5 mg/ml bsa (bsa-5), 3) extender containing 10 mg/ml bsa (bsa-10), and 4) exte...

Semen from four Holstein bulls was evaluated to compare effects of four extender treatments on postthaw semen quality. Extender fractions A and B, either heated whole milk or 20% egg yolk-citrate, were combined to yield the extender treatments 1) milk and milk, 2) milk and egg yolk-citrate, 3) egg yolk-citrate and milk, and 4) egg yolk-citrate and egg yolk-citrate. Semen was evaluated at thawin...

the goal of this study was the evaluation of semen extender filtration on post-thawed buck sperm quality. a total 16 ejaculates were collected from four buck (4 ejaculates from each buck) twice a week. after semen collection and primary evaluation, collected semen samples were pooled and divided into two equal parts. each part was diluted with one of the following extenders: 1) non-filtered lec...

the aim of this study was to determine the effects of the antioxidants superoxide dismutase (sod),glutathione peroxidase (gpx) and butylated hydroxytoluene (bht) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. ejaculates were collected from five holsteinbulls and pooled at 37°c. the semen samples were diluted with a cey extender containing addit...

BACKGROUND AND PURPOSE Allografts are often used during revision hip replacement surgery for stabilization of the implant. Resorption of the allograft may exceed new bone formation, and instability of the prosthesis can develop. We investigated whether strontium could regulate the imbalance of fast resorption of allograft and slower formation of new bone, because it is both an anabolic and an a...

The aim of this study was to determine the effects of the antioxidants superoxide dismutase (SOD),glutathione peroxidase (GPx) and butylated hydroxytoluene (BHT) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. Ejaculates were collected from five Holsteinbulls and pooled at 37°C. The semen samples were diluted with a CEY extender containing addit...
