OBJECTIVE Klotho has an important role in development of coronary artery (CAD) disease. A functional variant of klotho gene (kl-vs) has been found as an independent risk factor for early-onset occult coronary artery disease (CAD) in previous studies. The Frequency of this variant was not known in Iranian population. We have examined the allele frequency of the kl-vs variant in a case-control st...

BACKGROUND Friedreich ataxia (FRDA) is an autosomal recessive disorder caused by guanine-adenine-adenine (GAA) triplet expansions in the FXN gene. Its product, frataxin, which severely reduces in FRDA patients, leads to oxidative damage in mitochondria. The purpose of this study was to evaluate the triple nucleotide repeated expansions in Iranian FRDA patients and to elucidate distinguishable F...

BACKGROUND Based on the authors' knowledge, there is no study on the co-infection of opportunistic agents such as Mycobacterium tuberculosis and Pneumocystis jirovecii in the lungs of Iranian patients with immunosuppression. OBJECTIVES The current study aimed to show the rate of co-infection of M. tuberculosis and P. jirovecii in patients with Human Immunodeficiency Virus (HIV). PATIENTS AN...

BACKGROUND Previous studies revealed that the immune responses of depressed patients can be affected by alteration of immune system factors; however, the immune genes mainly influenced are yet to be fully understood. Therefore, the main aim of present study was to identify serum levels of drastic inflammatory cytokines including IL-17A, IL-12, and IL-6 as well as anti-inflammatory cytokines, IL...

BACKGROUND Hand Eczema (HE) is a dermatological disorder with frequent relapses and multiple causes such as atopic, allergic and irritant contact dermatitis. The management is complex because of the wide range of different pathogenesis. Efficacy of some of available treatments is not well established and it can affect patients' quality of life significantly. METHODS Reports on HE such as diag...

Implication for health policy makers/practice/research/medical education: Understanding the view of epidemiology of HCV infection in hemodialysis patients can help health policy makers for better decisions. Epidemiology of hepatitis C infection has changed during the recent years and I recommend all scientists to review the achievements in control of hepatitis C in Iranian hemodialysis patients...

BACKGROUND In the last decades cancer has become one of the important causes of death in Iran .This study examined perspective of a group of Iranian health professionals, patients and patients' family members regarding their view on disclosure of cancer information at a university hospital in Tehran, Iran. METHODS The method of study was qualitative semi-structured focused group content analy...

BACKGROUND The common GJB2 gene mutation (35delG) has been previously reported from Iranian patients that were affected with nonsyndromic autosomal recessive deafness. We, therefore, for the first time, investigated the prevalence and frequency of the GJB2 gene mutation in the Iranian deaf population with Arabian origins. MATERIALS AND METHODS We amplified and sequenced the entire coding sequ...

Breast Cancer is the most common cancer in Iranian women. Breast tumors negative and ER positive tumors. ER negative tumors tend to have worse prognosis and less likely to respond to endocrine therapy. Aberrant methylation of gene promoter is one of the mechanisms for gene silencing in breast tumors. Because of its reversible nature, promoter methylation is a good target for new therapeutic str...

BACKGROUND Inappropriate thromboprophylaxis is a serious problem in Iran. Venous thromboembolism (VTE) is one of the most important causes of morbidity in patients in surgical and obstetrics departments and intensive care units (ICUs). It is a leading preventable cause of mortality among in-patients. This study was designed to determine the prevalence of VTE and its epidemiology in an Iranian p...
