Background Familial hypercholesterolemia (FH) is a frequent autosomal dominant disorder of lipoprotein metabolism. This disorder is generally caused by mutations in low-density lipoprotein receptor (LDLR), apolipoprotein B 100 (APOB), and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes. In the present study, we aimed at identifying the common LDLR and APOB gene mutations in an Irani...

BACKGROUND Cleft lip with or without cleft palate (CL/P) is one of the most common congenital anomalies and the etiology of orofacial clefts is multifactorial. Transforming growth factor alpha (TGFA) is expressed at the medial edge epithelium of fusing palatal shelves during craniofacial development. In this study, the association of two important TGFA gene polymorphisms, BamHI (rs11466297) and...

Estrogen receptor alpha (ERα) is one of the major sub-types of estrogen receptors. ERα plays an important role in cellular proliferation and differentiation, chiefly in mammary tissues. In the present study we aimed to quantify of ERα mRNA and protein expression in breast tissues from the Iranian population using a real-time PCR assay. Twenty nine breast tissues including 19 adenocarcinomas and...

INTRODUCTION To determine the prevalence of the metabolic syndrome (MS) in an Iranian elderly population and show its association with coronary heart disease (CHD). MATERIALS AND METHODS This is a cross-sectional study on 720 Iranian men and women aged > or = 65 years who participated in the Tehran Lipid and Glucose Study (TLGS). Logistic regression analysis was used to estimate the odds rati...

The human leukocyte antigen (HLA)-G molecule is expressed in cytotrophoblast cells, adult thymic epithelial cells, erythroblasts, pancreatic islets and mesenchymal stem cells. Although, HLA-G expression in allotransplanted patients is correlated with a better allograft acceptance, it is associated with an advanced grade of the tumor in cancer. In addition to the role on the immune system, HLA-G...

Templates are very useful tools for diagnosis of malocclusions. A number of templates have been provided for some populations in previous years. Since craniofacial characteristics of different ethnic groups are not the same, each population needs its own norms. The aim of this study was to provide orthodontic craniofacial templates for 8-16 year old Iranian boys and compare dentoskeletal featur...

INTRODUCTION This study evaluated the health-related quality of life (HRQOL) in a sample of Iranian patients undergoing maintenance hemodialysis. The data were compared with the HRQOL for the Iranian general population. MATERIALS AND METHODS Two-hundred and fifty patients undergoing hemodialysis were included using a convenience sampling approach in a cross-sectional study. Data collection wa...

BACKGROUND & OBJECTIVES Attention deficit hyperactivity disorder (ADHD) is a common heritable psychiatric disorder with a worldwide prevalence of 5%. The etiology of ADHD is still incompletely understood, but several studies, consistently indicate the strong role of genetic factors on this disorder. The aim of this study was to determine the effect of three SNPs rs11122319, rs11122330 and rs667...

BACKGROUND The impact of the metabolic syndrome among populations in the Middle East region is unknown; we therefore examined the association between the syndrome and the risk of ischemic heart disease (IHD) in an Iranian population. METHODS AND RESULTS The Isfahan Cohort Study (ICS) prospectively followed 6146 Iranian people (51.8% women, aged 35-75 years) from three cities and their rural d...

AIM OF THE STUDY A recent breast cancer genome-wide association study (GWAS) identified single-nucleotide polymorphism (SNP) rs2046210 on 6q25.1 showing a strong association with breast cancer risk. Numerous association studies have been conducted to investigate the relationship between this polymorphism and breast cancer risk in various populations. There have been conflicting reports about th...
