Objective: The paraoxonase 1 (PON-1) enzyme is an important antioxidant. balance between oxidative stress and antioxidant defense mechanisms disturbed during asthma attacks. activity of the PON-1 related to gene polymorphism. This study aimed evaluate Q192R polymorphism in asthmatic children. Material methods: During 2013-2014 period, we performed a prospective with 34 (study group) healthy (co...
Background The tumor necrosis factor alpha (TNF-α) gene is a cytokine involved in systemic inflammation. Results of the association of its polymorphisms with infertility in men are controversial. Objective The aim of this study was to evaluate the association of -308G/A polymorphism in TNF-α gene with different parameters of semen and sperm in infertile men. Methods Participants were 210 me...
Association Between β-Defensin Gene Polymorphism and Clinical Mastitis in Holstein Dairy Cows: A Case-Control Study
Background: The 5, 10-methyleneterahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) are two essential enzymes involved in folate metabolism. The relationship between genetic polymorphisms and congenital heart defects (CHDs) is inconsistent. Our aim was to investigate the association between two well-known polymorphisms of MTHFR and MTRR genes, C677T and A66G, respectively,...
Background and purpose: Cytokines are a group of endogenous proteins which play an influential role in regulating the inflammatory responses and defeating infectious diseases. Elevated levels of proinflammatory cytokines and their receptors are usually observed in association with immune responses against viral infections such as hepatitis B virus (HBV) infection. IL 12 and its receptor play an...
