To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBan...

OBJECTIVE To study the clinical presentation, histology and colonoscopic features of lower gastrointestinal polyps in Iranian children. MATERIAL AND METHODS Medical reports of children with colorectal polyps were retrospectively reviewed from 1996 to 2005 at the Children's Medical Center Hospital, Iran. A total of 563 cases were studied. Data related to age, sex, family history, signs and sym...

background: the haplotype phasing is more useful than genotyping markers independently at carrier detection and prena­tal diagnosis of diseases. the pah gene region contains several markers used in detection of pku disease. in the present study, the efficiency of bgl ii- ecor i-vntr haplotype phasing in iranian family trios was investigated. then, this informa­tion was compared with those obtai...

Cognitive impairment or intellectual disability (ID) is a widespread neurodevelopmental disorder characterized by low IQ (below 70). ID is genetically heterogeneous and is estimated to affect 1-3% of the world's population. In affected children from consanguineous families, autosomal recessive inheritance is common, and identifying the underlying genetic cause is an important issue in clinical ...

BACKGROUND Infertility may prevent couples to achieve the desired social roles and lead to some social and psychological problems. This study aimed to explain the social consequences of infertility in Iranian women seeking treatment. MATERIALS AND METHODS A qualitative content analysis was conducted based on 32 semi-structured interviews with 25 women affected by primary and secondary inferti...

BACKGROUND Allele variants of COL11A2, encoding collagen type XI alpha2, cause autosomal dominant non-syndromic hearing loss (ARNSHL) at the DFNA13 locus (MIM 601868) and various syndromes that include a deafness phenotype. OBJECTIVE To describe a genome-wide scan carried out on a consanguineous Iranian family segregating ARNSHL. RESULTS Genotyping data identified a novel locus for ARNSHL o...

BACKGROUND Low-back pain is one of the most common human morbidities worldwide, which is damaging individually, socially and economically. Recent studies have shown that its prevalence is rising. Most of the low-back pains are non-specific though specific ones need more complicated and more expensive treatments. Sciatica or lumbar radiculopathy is one of these specific low-back pains and is exp...

To visualize the structure of Iranian chemistry scientific publications in SciSearch, 43 Iranian and International chemists were identified. They were the highly cited scientists in 7682 Iranian chemistry publications (defined as an article with at least one Iranian author address) indexed in Science Citation Index during the period from 1990 to 2006. Co-citation data for these authors from the...

OBJECTIVES The aim of this study was to detect the genetic cause of deafness in a large Iranian family. Due to the importance of SLC26A4 in causing hearing loss, information about the gene mutations can be beneficial in molecular detection and management of deaf patients. METHODS We investigated the genetic etiology in a large consanguineous family with 9 deaf patients from Fars province of I...
