Background: Lipopolysaccharide (LPS) is a major component of Chlamydia spp, and of all Gram-negative bacteria. The role of LPS in alteration of sperm parameters is controversial. In this study quantification of Chlamydia-specific and general lipopolysaccharide in semen was correlated to semen quality. Materials and Methods: 255 male partners of infertile couples were recruited to produce urine ...

In this study, age-dependent changes of sperm quality parameters in Rutilus frisii were investigated. Also, fertilization capacity of breeders was tested using two age groups of males (3 and 4 year old breeders) and one female group (i.e. 4 year old breeders). For fertilization trials, the breeders were crossed randomly among age classes. Between the two age groups, spermatological parameters d...

blood transfusion centers are under considerable pressure to produce platelet concentrates with high quality and safety due to the short shelf life of 3-5 days as well as possible bacterial and viral contaminations. for a variety of reasons, many europeans have changed their methods of component production from whole blood using the north american standard platelet-rich plasma method to the buf...

background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

background: the role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. this study was performed to evaluate the possible protective effect of vitamins e and c, against endosulfan-induced reproductive toxicity in rats. methods: fifty adult male sprague–dawley rats were randomly divided into five groups (n=10 each). the groups included a control receiving vehicl...

fluctuations in salinity impose stress on the physiology of the exposed fish population and can modify their structure. it has been noted that changes in blood characteristics and plasma levels serve as the primary link between environmental change and physiological response (mccormick, 2001). ninety healthy adult cyprinuscarpio (c. carpio) were randomly divided into five groups and kept in sal...

Using of phytobiotics as fish feed additives have been interestingly increased during the recent decade. The aim of the current study was to evaluate the effect of individual and combined level of thyme and vitamin E in common carp. Juveniles were separately fed by four distinct diets including control (commercial diet without any additive), supplemented with 1% ground Shirazi thyme, supplement...

The stereoselective pharmacokinetic of Tramadol (T) and its main metabolites concerning the influence of CYP2D6 phenotype and gender on the phase I metabolism of this compound was studied after administration of 100 mg single oral dose of racemic T to 24 male and female subjects. The pharmacokinetic parameters were estimated from plasma concentrations of the analytes enantiomers. The metabolic ...
