oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. cadmium (cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. because of its long biological half-life (10–30 years), cdaccumulates in the biological systems. the present study was designed to assess the concen...

The seasons in the 1 year study were classified as rainy, transitional rainy-dry, dry, and transitional dry-rainy. Semen pH and the consistency of the testes did not vary between seasons or among rams. All other characteristics of semen and testis varied between rams. Significant seasonal differences were observed for ejaculate volume, mass, % motility, forward motility score and concentration ...

Bipolaris oryzae is a phytopathogenic fungus causing a brown spot disease in rice, and produces substance that strongly perturbs motility and membrane integrities of boar spermatozoa. The substance was isolated from the liquid culture of the fungal strain using extraction and a multi-step semi-preparative HPLC procedures. Based on the results of mass spectrometric and 2D NMR techniques, the bio...

achalasia is a primary motor disorder of the esophagus, in which esophageal emptying is impaired. diagnosis of achalasia is based on clinical findings and confirmed by radiologic, endoscopic and manometric evaluations. several treatments for achalasia have been introduced. we searched the pubmed database for original articles and meta-analyses about achalasia to summarize the current knowledge ...

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 electron m...

In this study, the quantitative and qualitative traits of semen were studied in seven rams of different breeds (Prolific Merino, Cokanski Tsigai, Barbados Blackbelly, Bábolna Tetra, Awassi, Ile de France and Suffolk), bred in Hungary. The semen parameters (density, volume, pH, mass motility, % motility, thawing and heat resistance), freezability of semen and the factors influencing these parame...

In certain Ras mutant cell lines, the inhibition of extracellular signal-regulated kinase (ERK) signaling increases RhoA activity and inhibits cell motility, which was attributed to a decrease in Fra-1 levels. Here we report a Fra-1-independent augmentation of RhoA signaling during short-term inhibition of ERK signaling. Using mass spectrometry-based proteomics, we identified guanine exchange f...

Studies suggest that children and adolescents with type 1 diabetes (T1DM) have suboptimal body composition with higher fat mass and lower bone mass. Aim of our study was to compare body composition of Indian children with type 1 diabetes with age gender matched healthy controls. In a cross-sectional study, body composition parameters were measured by DXA (Lunar DPX PRO, Total Body Densitometer)...

BACKGROUND Aspermia caused by exogenous testosterone limit its usage in late-onset hypogonadism (LOH) patients desiring fertility. Saikokaryukotsuboreito (SKRBT) is reported to improve serum testosterone and relieve LOH-related symptoms. However, it is unclear whether SKRBT affects fertility. We aimed to examine the effects of SKRBT on spermatogenesis and fertility in aging male mice. METHODS...
