BACKGROUND Hepatitis B virus (HBV) genotypes and mutations are gaining importance in determining the clinical course of chronic liver disease. OBJECTIVES To determine and compare the distribution of HBV genotypes and genomic variations in Pakistan to other parts of the world. PATIENTS AND METHODS We conducted a prospective study at Aga Khan University Hospital from December 2006 to December...

Hepatitis B virus (HBV) genotypes differ in their potential for causing disease. Consecutive patients with chronic HBV infection (CHBV) (n=122) and blood donors (n=67) positive for hepatitis B surface antigen and HBV DNA were genotyped using polymerase chain reaction-restriction fragment-length polymorphism. The ratio of male to female subjects was significantly higher in the blood donor group ...

Introduction: Angiotensin converting enzyme (ACE) is an exopeptidase that converts Angiotensin I to Angiotensin II. Angiotensin II is a potent vasoconstrictor and releases aldosterone, and have a critical role in hypertension. In this study, ACE insertion / deletion (I/D) polymorphism and ACE activity was determined in patients with coronary artery disease (CAD) and normal subjects. The corr...

Background and Aims: Hepatitis B virus (HBV) infects the liver and causes acute and chronic hepatitis, hepatocellular carcinoma and cirrhosis. HBV has been divided to eight genotypes (A–H) and subgenotypes of A, B, C and F. For the first time, we determined HBV genotypes in infected samples by INNO-LiPA method in Yazd, central province of Iran. Materials and Methods: This study was performed...

Primary cultures of stromal-vascular (S-V) cells from adipose tissue were used to evaluate characteristics of preadipocytes from lean and preobese fetuses at several ages (50, 75, and 110 d). In insulin-supplemented (1 microM) cultures (serum free) there was a significant age x fetal genotype interaction (P less than .01) for glycerol-phosphate dehydrogenase specific activity (GPDH); GPDH activ...

BACKGROUND Vascular endothelial growth factor (VEGF) is a potent multifunctional cytokine which plays a key role in the pathogenesis of diabetic micro-vascular complications. Human VEGF gene is said to be highly polymorphic. Insertion/deletion (I/D) polymorphism of the 18 bp fragment at -2549 position of the promoter region in VEGF gene is said to be of particular interest. The study was aimed ...

Background: Angiotensin converting enzyme (ACE) is the key enzyme, regulates blood pressure which encoded by 21kb gene that consists of 26 exons and located on chromosome 17, contains a polymorphism in form either Insertion (I) or Deletion (D). The aim was to study effect antihypertensive drugs patients essential hypertension associated with ACE polymorphism. Methods: Hypertensive were recruite...

Angiotensin II is the major effector molecule of renin-angiotensin system; its production can be conveniently interrupted by angiotensin-converting enzyme (ACE). Typical plasma levels of ACE accompany the I/D polymorphism; however, a controversy exists as to whether the DD genotype of the ACE polymorphism affects the risk for the development of coronary artery disease (CAD) and to what extent t...

background: spontaneous abortion is considered as the most complex problem during pregnancy. thrombophilia is resumed as a cause of recurrent pregnancy loss (rpl). glycoprotein iiia (gpiiia) gene is involved in thrombosis and abortion. angiotensin converting enzyme (ace) converts angiotensin i to angiotensin ii and is involved in thrombosis. the most common polymorphism in this gene is the inse...
