objective(s): it has been reported that the mutation of the pre-core (pc) and basal-core promoter (bcp) may play an important role in the development of hbv-related hepatocellular carcinoma (hcc). in this study the pc and bcp mutations were investigated in chronic hbv patients. materials and methods:in this study, 120 chronic hbv patients from golestan, northeast of iran who were not vaccinated...

Background: Mutation in NPM1 gene has been reported to be the most common genetic mutation in de novo acute myeloid leukemia (AML). AML with NPM1 gene mutation usually presents with higher initial leukocyte and blast cell counts and negative CD34 expression. We aimed to investigate the difference of initial leukocyte counts, bone marrow blast cell counts and expression of CD34 among patients wi...

introduction: cleft lips and cleft palates are common congenital abnormalities in children. various chromosomal loci have been suggested to be responsible the development of these abnormalities. the present study was carried out to investigate the association between the suspected genes (methylenetetrahydrofolate reductase [mthfr] a1298c and c677t) that might contribute into the etiology of the...

Objective(s):  Denaturing high performance liquid chromatography (DHPLC) is a high throughput approach for screening DNA sequence variations. To assess oven calibration, cartridge performance, buffer composition and stability, the WAVE Low and High Range Mutation Standards are employed to ensure reproducibility and accuracy of the chromatographic analysis. The purpose of this study was to provi...

the miru-vntr polymorphism and katg463 mutation are used to genotype the mycobacterium tuberculosis, but the correlation between them and inh-resistance were unknown. this study was aimed to explore whether etre polymorphism and katg463 mutation could predict the inh-resistance, and the relationship between etre polymorphism and katg463 mutation.the etre, katg463 mutation and drug resistance in...

background: about 10% of infertilities with obstructive azoospermia are congenital and caused by cf gene mutations. m469i mutation was observed for the first time in taiwanese patients. this mutation not only causes cf, but also may be the origin of infertility too. objective: in this study, we aimed in designing a rapid, reliable rflp-pcr procedure for detection of m469i mutation. the correlat...

β-thalassemia, a monogenic autosomal recessive disorder, is prevalent in middle east, particularly in iran. in iran, near to 20 mutations in the β-globin gene are introduced as common mutations with varying incidence frequencies in each city. therefore, detection and screening for couples at high risk can help to solve the problems of this disease. in this study, optimized genotyping of two com...
