background the molecular mechanism of hepatitis c-virus (hcv) genome-specific pathogenesis remains unclear. oxidative stress is an important pathophysiological mechanism in chronic hcv infection, but its relation to hcv genotypes has not been thoroughly examined. objectives in the present case-control study, the effect of diverse hcv genotypes on oxidative status changes was investigated. patie...

background: urinary oxalate and citrate are the keyfactors in caox urolithiasis of cats and gamma glutamyltransferase is a good test for assessment of kidney damage.favorable effects of cynodon dactylon on calcium oxalate stoneformation have recently been proved in rats. objectives: thepresent study was designed to investigate the alteration ofurinary oxalate, citrate, and ggt after administrat...

OBJECTIVE We aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population. METHODS A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up f...

INTRODUCTION AND OBJECTIVES Uric acid and gamma-glutamyl transferase are prognostic indicators in chronic heart failure. Nevertheless, the mechanism underlying the association between uric acid, gamma-glutamyl transferase, and chronic heart failure progression and prognosis remains largely unknown. METHODS The association of uric acid and gamma-glutamyl transferase with flow-mediated dilation...

The y-glutamyl transferase isoenzymes of bile were studied using electrophoretic, gel filtration, and ultracentrifugation techniques. In view of the known association of other biliary enzymes with lipids the effects of butanol extraction were investigated. The results show the presence of four isoenzymes ofy-glutamyl transferase in bile, differing in electrophoretic mobilities, molecular size, ...

Serum gamma-glutamyl transferase (GGT) has been widely used as an index of liver dysfunction and marker of alcohol intake. The last few years have seen improvements in these areas and advances in understanding of its physiological role in counteracting oxidative stress by breaking down extracellular glutathione and making its component amino acids available to the cells. Conditions that increas...

Intrigued by similar specificities of the hydra feeding receptor and y-glutamyl transferase activity toward GSH, we examined the possibility that these two GSH-bihding activities might reside in the same protein. We find that the two activities differ in specificity toward the y-glutamyl moiety of GSH. The hydra transferase recognizes L-azaserine, L-Glu, D-Glu and L-Gln. The feeding receptor re...

CONTEXT AND OBJECTIVE The location of embolism is associated with clinical findings and disease severity in cases of acute pulmonary embolism. The level of gamma-glutamyl transferase increases under oxidative stress-related conditions. In this study, we investigated whether gamma-glutamyl transferase levels could predict the location of pulmonary embolism. DESIGN AND SETTING Hospital-based cr...

Gamma-glutamyl transferase in serum is a better indicator of problem drinking than other liver enzymes or blood alcohol. Moreover, the stability of this enzyme makes it easier to analyze, and the analysis is inexpensive. However, interpretation of the data requires knowledge of previous medical history and drugs prescribed concurrently that may affect the serum levels of gamma-glutamyl transfer...
