Serum enzyme assays used on four different analysers (Hitachi 737, Hitachi 705, Cobas-bio and RA-2X) were compared by determining the activity of seven different enzymes (AST, ALT, LD, ALP, GGT, CK and AMS). Performance checks (quality control procedure) and replications (the study of the total analytic imprecision and of its components) were conducted and the methods were compared by linear re...

An enzymatic method for synthesizing various -D-glutamyl compounds efficiently and stereospecifically involving bacterial -glutamyltranspeptidase (EC 2.3.2.2) with D-glutamine as a -glutamyl donor was developed. With D-glutamine as a -glutamyl donor instead of L-glutamine in -glutamyltaurine synthesis, byproducts such as -glutamylglutamine and -glutamyl-glutamyltaurine were not synthesized and ...

A theoretical free energy study describes the inactivation of a new tuberculosis target, the l,d-transpeptidase 2 enzyme. A new reaction mechanism of two carbapenem inhibitors is proposed and their molecular features are determined using QM/MM and PMF approaches. The theoretical findings with the new proposed mechanism agree in principle with the experimental data.

Total protein (TP), albumin (Alb), transferrin (TRF), retinol-binding protein (RPB), N-acetyl-beta-glucosaminidase (NAG), alanine aminopeptidase (AAP), gamma-glutamyltransferase (GGT), and creatinine (Cr) were measured in random (untimed) urine samples from 29 nonpregnant women and from pregnant subjects (11 in the first trimester, 34 in the second, and 37 in the third). The excretion of TP, Al...

BACKGROUND AND AIMS The relationships between gamma-glutamyltransferase (GGT), C-reactive protein (CRP), and arterial stiffness have not been fully investigated. The aim of this study was to clarify whether serum GGT is related to CRP and arterial stiffness estimated using brachial-ankle pulse wave velocity (baPWV). METHODS AND RESULTS The subjects were 3412 males and 854 females. GGT, CRP, b...

[Purpose] The purpose of the study was to investigate the effects of action observation training on the static balance and walking ability of patients who had suffered a stroke. [Subjects] Forty patients with hemiplegia resulting from a stroke were divided into an action observation gait training group (AOGT group, n=20) and a general gait training group (GGT group, n=20). [Methods] The AOGT gr...

Circadian variations of alanine aminopeptidase (EC 3.4.11.2), gamma-glutamyltransferase (EC 2.3.2.2), and N-acetyl-beta-glucosaminidase (EC 3.2.1.30) in urine were studied in 10 healthy children, ages six to 15 years. Urine specimens were collected during 24 h, grouped into four time intervals. Enzymes were measured spectrophotometrically, with automation. These enzymes all showed diurnal varia...
