Hypertension, diabetes and obesity are cardiovascular risk factors closely associated to the development of renal and cardiovascular target organ damage. VAV2 and VAV3, members of the VAV family proto-oncogenes, are guanosine nucleotide exchange factors for the Rho and Rac GTPase family, which is related with cardiovascular homeostasis. We have analyzed the relationship between the presence of ...

Mannose-binding lectin (MBL) plays an important role in immune defense. This study was undertaken to investigate the association between hepatitis B virus infection and polymorphisms of MBL gene. We assessed the single nucleotide polymorphism at codon 54 in exon 1 of MBL in patients with hepatitis B virus infection and HBsAg negative controls in Korean population. A total of 498 enrolled subjec...

Purpose: The aim of this study was to investigate matrix metalloproteinase 1 (MMP-1) gene polymorphism (1G/2G at -1607 and A/G at -519) in Korean subject and to assess the association between polymorphism and periodontal status. Methods: Forty nine generalized aggressive periodontitis (GAP) patients and 57 periodontally healthy children were recruited and genomic DNA was extracted from buccal s...

AIM The purpose of this study was to investigate the possible influence of age and gender on association between -765G > C COX-2 genetic polymorphism and gastric adenocarcinoma risk in Iranian patients. BACKGROUND The promoter polymorphism of COX-2 gene -765G > C has been described to play an important role in many cancers such as gastric cancer. PATIENTS AND METHODS We carried out single-n...

Amygdala reactivity is a heritable trait, potentiated in affective disorders and associated with both the 5-HTTLPR and the COMTval158met polymorphism. Fifty-four healthy volunteers selected a priori based on gender and 5-HTTLPR/rs25531 and COMTval158met genotypes performed a passive viewing task of angry facial expressions using fMRI. Amygdala reactivity and habituation were investigated using ...

Studies investigating the relationship between common genetic variants and cancer risk are being reported with rapidly increasing frequency. We have identified 46 published case-control studies that have examined the effect of common alleles of 18 different genes on breast cancer risk. Of these, 12 report statistically significant associations, none of which were reported by more than one study...

BACKGROUND The aim of this study was to determine the relationship between a purported luteinizing hormone/chorionic gonadotropin (LHCGR) high function polymorphism (rs4539842/insLQ) and outcome to controlled ovarian hyperstimulation (COH). METHODS This was a prospective study of 172 patients undergoing COH at the Fertility and IVF Center at GWU. DNA was isolated from blood samples and a regi...

We aimed to find out if the serotonin receptor (HT102T>C) and serotonin transporter (STin 2) polymorphisms play any role in genetic susceptibility of migraine. For the study, 217 migraine patients and 217 healthy controls (HC) were recruited and genotyping was carried out using the Polymerase Chain Reaction and Restriction Fragment Length polymorphism (PCR-RFLP) method. All results were Bonferr...

in this work we introduce a practical use of synthesized schiff base metal complex in sensing application. a new perchlorate-selective electrode based on the complex n, n'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (ii) [cul] as the membrane carrier was developed. the electrode exhibits a good  nernstian slope of -55.0 ± 1.0 mv/decade and a linear range of  for perchlorate. the limit o...
