diabetes mellitus is a multifactorial disease. it has recently been shown that an insertion (i)/deletion (d) polymorphism exists in the angiotensin-converting enzyme (ace) gene that can affect the serum ace level. there are three genotypes: dd, di, and ii, with the ace level being highest in dd, intermediate in di, and lowest in ii. in the present investigation, 170 patients with type 2 diabete...

BACKGROUND A C1173T polymorphism in intron 1 of the VKORC1 gene has been claimed to determine the interindividual variability in the response to vitamin K antagonist therapy (VKA), but it is unknown whether it also influences bleeding risk. We aimed to confirm the relationship between C1173T status and phenprocoumon or acenocoumarol use, and to examine the risk of severe bleeding for the variou...

aim : the aim of study was to determine the preliminary result of treatment with pegasys in iranian chronic hepatitis b patients (with genotype d) referred to tehran hepatitis center (thc). background : the genotype of hbv and ethnicity of the patients can affect the response rate to pegasys. patients and methods : during 2006-2008, 12 patients with naïve chronic hepatitis b (genotype d) that r...

conclusions several previous studies used pcr-rflp to genotype hbv; however, we showed the high risk to obtain atypical profiles, especially in advanced stages of chronic infection, with as results difficulties to genotype the virus. these profiles resulted from the accumulation of mutations during natural course of infection resulting in a modification in restriction sites for enzymes. so, we ...

BACKGROUND The clinical outcome of chronic hepatitis B may depend on hepatitis B virus (HBV) genotype. Data from India on this aspect are limited and contradictory. We studied the frequency of HBV genotypes and their clinical significance. METHODS Stored sera from patients with chronic HBV infection were tested for HBV genotype using PCR-RFLP. Clinical data, and biochemical and serological pa...

BACKGROUND angiotensin-converting enzyme (ACE) gene insertion/deletion (indel) polymorphism is considered a biomarker for Alzheimer's disease (AD). However, the associations of ACE gene and protein level to AD are undetermined among Taiwanese. METHODS this study investigated 257 Taiwanese cases with AD and 137 ethnically matched controls using ACE gene indel genotype association methods with ...

conclusions genotype d was the main genotype detected in romanian patients with chronic hbv infection. genotype d presented both bcp and pc mutations more frequently. results we detected two hbv genotypes; a (8.1%) and d (60.5%), and a mixture of genotypes a and d (31.4%) (p < 0.001). basal core promoter (bcp) a1762t/g1764a and precore (pc) g1896a mutations were detected in these romanian patie...
