inflammatory bowel disease (ibd) is a chronic disease of unknown etiology, in which genetic factors, seem to play an important role in the disease predisposition and course. assessment of tumor necrosis factor (tnf-α) gene polymorphisms in many populations showed a possible association with ibd. considering the genetic variety in different ethnic groups, the aim of the present study was to inve...

patients and methods this cross - sectional study was conducted on 143 thalassemic patients with chronic hepatitis c, who were treated with a combination of peg-ifn and rbv regimen. the rs12979860 and rs8099917 polymorphisms were assessed as the most common polymorphisms near the il28b gene by the polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) method. objectives w...

This study aimed to investigate the association between polymorphisms in fibrinogen genes and bleeding risk patients receiving direct oral anticoagulants (DOACs).

Background: Telomere length is associated with cancer as well aging. Telomerase reverse transcriptase (TERT), telomere RNA component (TERC) and oligonucleotide/oligosaccharide-binding fold containing 1 (OBFC1) are known to be involved in regulation. The tumor suppressor p53 (TP53), which has been shown interact protein p53-binding (TP53BP1), implicated the response shortening Polymorphisms TP53...

Background: Hemophilia B is an X-linked recessive coagulation disorder caused by factor IX deficiency.  Analysis of factor IX gene polymorphisms is considered the best approach for prenatal diagnosis and carrier detection of hemophilia B where the identification of gene mutation is not easily possible. Objective: To study the frequency of three factor IX-linked restriction fragment length polym...

Background: The role of apolipoprotien E polymorphisms do not diagnostic correctly in recurrent pregnancy loss etiology but Apo E has been shown to play an important role in lipid metabolism in pregnancy. We evaluated these polymorphisms in Iranian women with unexplained recurrent pregnancy loss. Materials and Methods: 5 ml Blood were sampling from 81 women with a history of two or more consecu...

Objective(s) Deregulation of the immune system through allied factors and cytokine responses are thought to be important contributors to the pathogenesis of asthma. Vitamin D3 and its nuclear receptor appear to be factors that maybe involved in regulating immune responses during the progression of asthma. The aim of this study was to investigate the association between polymorphisms in intron ...

background: the most common polymorphisms identified in the methylenetetrahydrofolate reductase (mthfr) gene, c677t and a1298c lead to defective activity of this enzyme and increase the risk of venous and arterial thrombosis. there are limited investigations regarding the effects of thrombogenic polymorphisms on the clinical phenotypes of rare hereditary hemorrhagic disorders like glanzmann's t...

background: recurrent pregnancy loss is (rpl) a heterogeneous condition. while the role of acquired thrombophilia has been accepted as an etiology for rpl, the contribution of specific inherited thrombophilic gene polymorphisms to the disorder has been remained controversial. methods: one hundred women with a history of two or more consecutive abortions and 100 women with at least two live birt...
