background pseudomonas aeruginosa is a leading cause of infections especially in patients with weakened immune systems. this pathogen is intrinsically resistant to many antibacterial agents. objectives the aim of this study was to survey the antibiotic resistance pattern and frequency of bla oxa10 gene in carbapenemase producing p. aeruginosa isolated from patients in isfahan hospitals. materia...

background: endometriosis is a female health disorder that occurs when cells from the lining of the uterus grow in other areas of the body. the cause of endometriosis is unknown. objective: the purpose of this study was to investigate tp53 gene codon 72 polymorphism in women with endometriosis and compared it with healthy samples in isfahan. materials and methods: we undertook a case-control st...

abstract       background and objective: baba2 and hpa genes are involved in adherence of helicobacter pylori (h.pylori) to gastric mucosal tissue. this study aimed to investigate the frequency of these genes in isolates of h. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer.       methods: gastric biopsy samples were obtained from patients wit...

the restriction enzyme ava ii detects the base change of the intervening sequence ii (ivs ii) which is used as one of the markers of β-globin gene polymorphism. this study was conducted to determine the frequency of the ava ii site on the β-globin gene among normal people and patients with sickle cell syndrome (scs) in iran. dna fragments containing the ivs ii region of the β-globin gene from 3...

background: hearing loss (hl) is the most frequent neurosensory impairment. hl is highly heterogeneous defect. this disorder affects 1 out of 500 newborns. this study aimed to determine the role of dfnb2 locus and frequency of myo7a gene mutations in a population from west of iran. methods: thirty families investigated in shahrekord university of medical sciences in 2014, genetic linkage analys...

background: the majority of α-thalassemi mutations are deletions of one or both α-globin genes. since the iranian populaion is a mixture of different ethnic groups, frequency and distribution of globin mutations in various regions of the country need to be clarified. the aim of this study was to determine the common alpha globin gene deletions among individuals with hypochromic microcytic anemi...

background: there are no data on the frequency and biochemical expression of the hemochromatosis associated mutations, c282y and h63d, in iranian adult population. this is the first study among iranians that may advocate a screening program. materials and methods: we investigated the frequency of the c282y/h63d hfe gene mutations in a group of 1029 randomly selected iranian blood donors as well...

nitric oxide is an important vasorelaxant factor that it inhibits platelet adhesion and proliferation of smooth muscle cells. no is synthesized from l-arginine by means of endothelial nitric oxide synthase (enos) which is an isoform of  nitric oxide synthase.in the present study, we examined  possible association between the 27 base pair (bp) repeat  polymorphism in intron 4 of the  enos3 gene ...

background: hla-g gene contains 15 alleles including a null allele, hla-g*0105n. previous studies have shown that hla-g*0105n does not encode the complete hla-g1 or hla-g5 isoforms but encodes a functional hla-g protein with the ability to in-hibit nk cell cytolysis. thus, although the biological functions of hla-g1 and hla-g5 proteins are abrogated, other isoforms such as hla-g2 can replace th...

phenylketonuria (pku) is one of the most common metabolic inborn diseases caused by mutations in the phenylalanine hydroxylase (pah) gene. this gene is linked to a variable number of tandem repeats (vntr) region which is a polymorphic marker that facilitates the implementation of prenatal diagnosis and carrier screening. in this study, vntr with 13 repeats that has not been reported previously ...
