background: beta thalassemia gene mutations are among common mutations in southwest iran. however, hemoglobin e (hb e) and hb e/β⁰ thalassemia account for a small number of hemoglobinopathies in iran. this is the first study to directly address the existence of hb e and consequently hb e/β⁰ thalassemia in southwest iran. methods: this retrospective study discovered seven cases of hb e/β⁰ thalas...

BACKGROUND The CD1 family is less variable transmembrane antigen presenting molecules related to the MHC molecules. CD1a and CD1e genes are the most polymorphic ones associated with autoimmune diseases. The aim was to better clarify the map of CD1 genes in Southwest Iranian normal population for implications in vaccine design. METHODS In this study we investigated the polymorphism of CD1a, CD...

Background and Objectives: Mutation directed inactivation of the tumor suppressor gene p53 have been found in countries with high frequency for hepatocellular carcinomas (HCCs). Our goal in the present study was screening of the p53 gene in tumor tissues from HCC affected individuals in southwest Iran for putative mutations in exons 7 and 8 that are known as hot spot regions. Materials & Method...

The efficacy of bacterial cultures and IS900-specific polymerase chain reaction (PCR) was compared for the detection of Mycobacterium avium subsp. paratuberculosis (MAP) from the mesenteric lymph nodes of goats. Samples were collected from 75 goats slaughtered in Ilam, in southwest of Iran. Tissue homogenates were inoculated onto four media. The genomic DNA was extracted directly from mesenteri...

BACKGROUNDS Genus Trichostrongylus (Nematoda: Trichostrongylidae) is one of the most important zoonotic nematodes with wide geographic distribution in the world. The purpose of the present study was to describe morphological and morphometrical characteristics of male Trichostrongylus species, currently prevalent in domestic ruminants of Khuzestan Province, southwest Iran. METHODS Gastro-intes...

OBJECTIVE NIEMANN PICK DISEASE (NPD) TYPE A (NPA: MIM #257200) is a lipid storage disorder with an autosomal recessive inheritance and occurrs by defect of the SMPD1 gene encoding sphingomyelinase. Disruption of this enzyme leads to the accumulation of sphingomyelin in brain and liver, which in turn causes dysfunction or damage of tissue. METHODS We report firstly a 2.5 year old boy with NPA ...

BACKGROUND External genital warts (EGW) are relatively common sexually transmitted diseases. In the majority of cases, low-risk human papilomaviruses (HPV), such as HPV-6 and HPV-11, are responsible but, high-risk types may also be detected and this has a bearing on vaccines for cervical cancer prevention. In this study the incidence of the high-risk HPV types 16, 18, 33 and 52 in EGWs of femal...

UNLABELLED BACKGROUND Hepatitis C virus (HCV) infection is responsible for considerable morbidity and mortality worldwide. The HCV genotype has a geographic distribution and an important role in clinical and histological outcomes. This study determined HCV genotypes and their related risk factors among patients from Khuzestan Province, Southwest Iran. METHODS In a cross-sectional study, 223 pat...

BACKGROUND Parasites affect the health and productivity of birds. Haemoproteus columbae occurs in pigeons widely in tropical and subtropical regions. The present investigation was concentrated on the prevalence of H. columbae and rate of parasitemia in domestic pigeons in southwest of Iran. METHODS Pigeons regimented in three groups, less than six months old, between six and twenty four month...

BACKGROUND Respiratory allergies are the most important public health issues in the world. They are caused by aeroallergens which play great role in pathogenesis of respiratory allergic diseases. METHODS The current study was conducted to evaluate the prevalence of positive skin test for various aeroallergens among allergic patients in Ahvaz, southwest Iran. 299 participants with allergic rhi...
