the underlying mechanisms leading to the development of human t-cell lymphotropic virus type i (htlv-i) associated myelopathy/tropical spastic paraparesis (ham/tsp) in htlv-i infected individuals are not fully understood. host genetic factors appear to be involved as risk factors for developing ham/tsp. we investigated the possible contribution of interleukin-10 (il-10) as a risk factor to ham/...

the environmental procarcinogen which are responcible for carcinogenesis, to form the proximate carcinogen, they require metabolic activation by drug metabolizing enzymes. the cyp3a subfamily enzymes play an important role in elimination of drugs. the substrates for cyp3a4 enzyme include drugs, and endogenous substances. therefore, allelic changes in the coding regions of cyp3a4, increases the ...

background: although catalytic properties of different genetic polymorphisms of vkorc1 and cyp2c9 products have been identified, there is limited study available regarding warfarin dose requirement in iranian patient population. this study investigates the impact of these polymorphisms on 115 patients, referred to payvand clinical and specialty laboratory for determining the appropriate dose of...

Pediculus humanus capitis, the head louse, is an obligate blood-sucking ectoparasite that occurs in six divergent mitochondrial clades (A, D, B, F, C and E). Several studies reported presence of different pathogenic agents lice specimens collected worldwide. These findings suggest louse could be a dangerous vector serious public health problem. Herein, we aimed to study genetic diversity, PHUM5...

The receptor for advanced glycation end products (RAGE) is a transmembrane protein that interacts with its ligands, (AGEs). AGEs are elevated in diabetes and diabetic complications, leading to increased oxidative stress activation of pro-inflammatory pathways facilitated by AGE–RAGE signaling. Polymorphisms the RAGE gene can potentially affect interaction downstream signaling, which plays cruci...

introduction genetic background has known to be associated with the outcome of human t cell lymphotropic virus (htlv) type i infection. in the present study we investigate the association between gm-csf gene polymorphisms with the outcome of htlv-i infection. materials and methods we analyzed 3 single-nucleotide polymorphisms in the promter region of granulocyte macrophage colony stimulating fa...

conclusions the at1r a1166c polymorphism appeared not to be associated with the presence of acs in the population studied. background there are very limited data for iranian populations on the predisposing genetic factors for acute coronary syndrome (acs). results there was no statistical difference in the genotype frequency of patients and healthy subjects with regard to age and gender (p > 0....

Gastric cancer (GC), the third leading cause of cancer-related deaths in Mexico and worldwide, can be classified into diffuse (DGC) or intestinal (IGC) types based on its histological characteristics. DGC is characterized by reduced expression of the cell adhesion protein E-cadherin, which is encoded by CDH1. The -472delA (rs5030625) and -160C>A (rs16260) polymorphisms in CDH1 induce a decrease...

The performance of a silica chip-based resequencing method, the Affymetrix HIV PRT 440 assay (hereafter referred to as the Affymetrix assay), was evaluated on a panel of well-characterized nonclade B viral isolates and on isolates exhibiting length polymorphisms. Sequencing of human immunodeficiency virus type 1 (HIV-1) pol cDNAs from clades A, C, D, E, and F resulted in clade-specific regions ...

BACKGROUND Few studies have investigated the association between Apolipoprotein E (APOE) polymorphisms and chronic kidney disease (CKD) in the general population, and their results are inconsistent. METHODS The current study population was composed of 9,033 subjects aged ≥ 50 years who participated in the baseline survey of the Dong-gu Study, which was conducted in Korea between 2007 and 2010...
