in order to evaluate the effects of phenytoin on the reproductive system of rats in detail, 60 male rats were divided equally into 6 groups: 1-5 received 10 mg/kg/day phenytoin ip for 1,2,3,4 and 5 weeks, respectively. however, group 5 did not receive any phenytoin for the last 5th week. the control group (group 6) did not receive any treatment. the results revealed that phenytoin does not have...

Understanding flow and transport of bacteria in porous media is crucial to technologies such as bioremediation, biomineralization or enhanced oil recovery. While physicochemical filtration well-documented, recent studies showed that bacterial motility plays a key role the process. Flow experiments performed microfluidic chips containing randomly placed obstacles confirmed distributions non-moti...

The present study investigated the existing relationship between computer assisted semen motility parameters and gametes motility duration, known to express semen quality and fertilizing capacity in fish. The objective was particularly to identify computer aided semen analysis (CASA) parameters that could be used as potential fertility predictors. Semen samples were collected from the beginning...

Motility parameters of the spermatozoa in most fish species spawning in fresh water like Rutilus kutum lasts for a short time after activation. Ovarian fluid significantly influenced sperm motility (motility duration period) and percent motility (progressive forward motile sperm). Both of these variables generally increased as the concentration of ovarian fluid increased from 33% to 50%, respec...

The swim-up procedure was used to collect a sperm fraction with improved motility and normal morphology from fertile and infertile semen samples. The untreated and swim-up fractions were analyzed with the Hamilton-Thorn Motility Analyser. Comparisons were made to see the effect of this sperm selection technique on sperm motility and morphology. They were then examined by transmission elect...

Artificial insemination using sexing semen is expected to produce calves with the desired sex. One sperm method percoll density gradient centrifugation method. This study aimed determine changes and relationship between motility acrosome reaction after process centrifugation. The material used was of ±5 years old Ongole crossbred bull a bodyweight ±700 kg as many three bulls mass 2+ individual ...

background: curcumin has shown to affect sperm motility and function in vitro and fertility in vivo. the molecular mechanism(s) by which curcumin affects sperm motility has not been delineated. since modulation of intracellular ph (phi) and plasma membrane polarization is involved in sperm motility, the present study was conducted to investigate the effect of curcumin on these sperm (human and ...

To compare the reproductive performance of the wild and cultured stocks of beluga, Huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and larval growth and survival rates. The semen samples were sampled from 11 wild spawners and 12 cultured brooders. A half of each semen sample was allo...
