Venom of the desert black snake enhances anti-tumor immunity via its beneficial modulatory effects on pro- and anti-tumorigenic inflammatory mediators in cultured colon cancer cells.

The role of inflammation in colon cancer is understood as a well-accepted factor that has the tendency to release multiple pro- and anti-tumorigenic inflammatory mediators. Inflammation-induced increased expression of anti-tumorigenic inflammatory mediators and decreased expression of pro-tumorigenic inflammatory mediators encourage beneficial inflammatory effects in terms of powerful anti-tumor immunity. The present study aims to screen the beneficial inflammatory effects of venom via determining its modulatory tendency on the expression of 40 pro- and anti-tumorigenic inflammatory mediators (cytokines/growth factors/chemokines) in LoVo human colon cancer cell line.

Influence of KISS1 gene polymorphisms on the risk of polycystic ovary syndrome and its associated variables, in Saudi women.

Background: Polycystic ovary syndrome (PCOS) is a complex multifactorial disorder, affecting millions of women worldwide. The role of genetic polymorphisms of the KISS1 gene on the development of PCOS is still obscure. This study was designed to investigate the probable influence of KISS1 gene polymorphisms on PCOS and its associated variables: BMI, waist-hip ratio, kisspeptin, LH, FSH, and LH-FSH ratio.

Relevance of gene polymorphisms in susceptibility to polycystic ovary syndrome and its associated endocrine and metabolic disturbances.

: Variations in may be an emerging factor in polycystic ovary syndrome (PCOS) We hypothesised links between polymorphisms in PCOS and its associated endocrine and metabolic disturbances. : The study included 104 PCOS women and 109 controls. Endocrine (kisspeptin, LH, FSH, LH-FSH ratio, oestradiol) and metabolic (cholesterol, triglycerides, HDL, LDL, insulin and glucose) parameters were measured.

Genotoxicity and oxidative stress in chromium-exposed tannery workers in North India.

Trivalent chromium (Cr) is an environmental contaminant, which is extensively used in tanning industries throughout the world and causes various forms of health hazards in tannery workers. Therefore, a cross-sectional study design was used to evaluate the DNA damage and oxidative stress condition in tannery workers exposed to Cr in North India. The study population comprised 100 male tanners in the exposed group and 100 healthy males (no history of Cr exposure) in the comparable control group.

Assessment of health risks with reference to oxidative stress and DNA damage in chromium exposed population.

Trivalent chromium [Cr(III)] is widely used in tanning industrial processes. The population living in tanning industrial area is continuously exposed to Cr(III) which appears to be associated with both acute and chronic health problems. Therefore, the aim of this study was to evaluate the health risk with special reference to oxidative stress parameters (malondialdehyde - MDA, glutathione - GSH, and superoxide dismutase - SOD) and DNA damage in 100 Cr-exposed and 100 unexposed populations.
