Isolation and characterization of the plasma membrane of rat cauda epididymal spermatozoa
Isolation characterization plasma membrane rat cauda epididymal spermatozoa
2009/2/23
Cauda epididymal rat spermatozoa were isolated by flushing the excised epididymis and the plasma membrane was detached by a nitrogen cavitation treatment (500 psi, 10 minutes equilibration at 4 C)...
Effect of gossypol acetate on guinea pig epididymal spermatozoa in vivo and their susceptibility to capacitation in vitro
gossypol sperm motility sperm maturation cytoplasmic droplet capacitation acrosome reaction
2009/2/20
To determine the effects of gossypol acetate on guinea pig epididymal and vas deferens sperm maturity and in vivo susceptibility to in vitro capacitation and the acrosome reaction, we examined sperm...
The Effects of Cyclic Adenine Nucleotides, Phosphodiesterase Inhibitors, and Cauda Epididymidal Fluid on the Motility of Rat Epididymal Spermatozoa
spermatozoa motility epididymal rat
2009/2/19
Experiments were performed to determine whether the rat epididymis secretes a "forward-motility" factor(s) similar to that found by others in the bovine epididymis. Lumen content of the rat caput ...
Glycosidic specificity of fucosyltransferases present in rat epididymal spermatozoa
Glycosidic specificity fucosyltransferases present rat epididymal spermatozoa
2009/2/13
We have recently demonstrated multiple fucosyltransferase (FT) activity in rat spermatogenic cells. To complement these findings, here we identify and partially characterize the glycosidic linkage s...
Stimulation of cryopreserved epididymal spermatozoa of the domestic cat using the motility stimulants caffeine, pentoxifylline, and 2'-deoxyadenosine
Domestic cat motility stimulants hyperactivation
2009/2/12
We have investigated the effects of caffeine, pentoxifylline, and 2'-deoxyadenosine on the motion characteristics and longevity of domestic cat spermatozoa. Freshly collected or cryopreserved dome...
