background: breast cancer is the first leading cause of cancer-related death in women. pesticides which are excessively used in northern iran are one of the most important risk factors for breast cancer incidence. the cytochrome p450 1a1 (cyp1a1) is a key enzyme in xenobiotics metabolism and snps of its coding gene has been verified to be important in cancer susceptibility. the aim of this stud...

b a ckground: the objective was to investigate the relationship between serum interleukin-18 (il-18), pentraxin 3 (ptx3), and high-sensitivity c-reactive protein (hs-crp) levels with body mass index (bmi) and abdominal obesity and also the interaction between genetic variants of apolipoprotein a-ii (apo a-ii) and obesity on the levels of these factors in type 2 diabetes patients (t2d). m ethods...

the present study investigated the calpain gene diversity in iranian one-hump camels (120 camels) using pcr-rflp method. three genotypes aa, ag and gg were observed with the frequencies of 0.02, 0.19 and 0.78, respectively. the frequencies of a and g alleles were 0.12 and 0.88, respectively. the chi-squared test didn’t show significant deviations from hardy-weinberg equilibrium (p<0.05). associ...

background: we studied the role of maternal folic acid supplementation in modifying the effects of  methylenetetrahydrofolate reductase (mthfr c677t and a1298c) gene polymorphisms in iranian children with oral clefts. materials and methods: forty?seven newborn infants with orofacial cleft and their mothers were selected randomly. mothers were matched regarding dietary folate intake.the genotypi...

background and purpose: vulvovaginal candidiasis is a frequent disease affecting approximately more than %75 of all childbearing women at least once in their lifetime by overgrowth of opportunistic candida species. recurrent vulvovaginal candidiasis (rvvc) is common in otherwise healthy individuals. several risk factors were reported to contribute to rvvc susceptibility. a polymorphism in decti...

alzheimer's disease (ad) is a genetically heterogeneous neurodegenerative disease and late-onset type (load) is the most common form of dementia affecting people over 65 years old. calhm1 (p86l) encodes a transmembrane glycoprotein that controls cytosolic ca2+ concentrations and aß levels and p86l polymorphism in this gene is significantly associated with load in independent case controls in a ...

late-onset alzheimer's disease (load) is a neurodegenerative disorder and the most common form of dementia affecting people over 65 years old. alzheimer’s disease is a complex disease with multi-factorial etiology. inflammation has been approved to have an important role in the pathogenesis of alzheimer’s disease (ad). tnf-a is a main pro-inflammatory cytokine that plays an essential role in in...

background: the prevalence of hepatitis c virus (hcv) infection is increasing worldwide. cytotoxic t-lymphocyte-associated protein 4 (ctla-4) may play a role in the intensity of the disease. the aim of this study was to evaluate the association between genetic variants of the ctla-4 and hcv infection. methods: restriction fragment length polymorphism-polymerase chain reaction (rflp-pcr) was per...

the pituitary-specific transcription factor (pit1) gene is responsible for pituitary development and hormone secreting gene expression in mammals. pit-1 is studied as a candidate genetic marker for growth, carcass and also for milk yield traits. in dairy farm animals, the principal goal of the selection is the improvement of milk yield and composition. the genes of milk proteins and hormones ar...

background: for the first time we tested an association between the human multidrug resistance gene 1 (mdr1) polymorphisms (snps) and idiopathic pulmonary fibrosis (ipf). several mdr1 polymorphisms are associated with pathologies in which they modify the drug susceptibility and pharmacokinetics. materials and methods: we genotyped three mdr1 polymorphisms of 48 ipf patients and 100 control subj...
