More than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. Kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. The present study describes polymorphism of kappa casein gene. This is the first study of kappa casein gene polymorphism in Najdi cattle of Iran. We used the polymerase chain r...

  Background :Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is an important negative regulator of T-cell responses. The -1722TC polymorphism of the CTLA-4 gene may be associated with systemic lupus erythematosus (SLE) risk, but related results from previous studies have been inconsistent. We carried out a meta-analysis to assess this association more precisely.   Methods : A systematic s...

Abstract Tuberculosis and diabetes mellitus are the most important reasons in mortality all over the world. It’s clear that reviewing of relationship between Tuberculosis (TB) and diabetes mellitus (DM) is necessary; on the other hand it’s found that FTO gene has the positive relationship with metabolic issues. Therefore, it’s necessary pay attention to the above and danger...

background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocal­cin and cross laps. the fok i polymorphism in ...

background : colorectal cancer is the second cause of mortality in developed countries. the p53gene and some of it's polymorphisms are among the causes for cancer development.the purpose of this study is to evaluate the relationship between the p53 codon 72 polymorphism in colorectal adenocarcinoma specimens compared with controls. materials and methods : we performed a case-control study among...

results a number of 7-11 repeats in the spa gene xr region were determined. strains with 10 repeats were65%, therefore they had the highest percentage in isolates. seven repeats strains were 20% and each of the strains with 8, 9 and 11 repeats had the frequency of 5%. s. aureus strains antibiotic resistance was 35%, 5%, 45% and 40% for tetracycline, amoxicillin, gentamicin and erythromycin resp...

although genetic variants that affect susceptibility to coronary artery disease (cad) have been greatly known, a number of these single nucleotide polymorphisms (snps) remain to be analyzed in populations with different ethnicities. cad is influenced by numerous genetic, environmental, and lifestyle factors, and is an important reason for mortality around the globe. in this study, a novel snp (...

background:diabetic retinopathy (dr) is a sight-threatening microvascular complication of diabetes in which the vascular endothelium is damaged due to oxidative stress and inflammation, and vitreous vegf concentration becomes elevated. the aim of the present study was to assess the association of dr with genetic variations of the mnsod, a major antioxidant enzyme, and vegf, an important mediato...
