BACKGROUND AND AIMS Rice (Oryza sativa) plants lose significant amounts of volatile NH(3) from their leaves, but it has not been shown that this is a consequence of photorespiration. Involvement of photorespiration in NH(3) emission and the role of glutamine synthetase (GS) on NH(3) recycling were investigated using two rice cultivars with different GS activities. METHODS NH(3) emission (AER)...
BACKGROUND Gallstones (GS) in the gallbladder (GB) can be responsible for a whole spectrum of disease entities which may lead to a surgical emergency with high mortality. Diabetes mellitus (DM) is a debilitating disease that affects all systems in the body, and literature documents a higher incidence of gallstone disease (GSD) and its complications in diabetics than in the non-diabetic populati...
PURPOSE GS-9219, a novel prodrug of the nucleotide analogue 9-(2-phosphonylmethoxyethyl)guanine (PMEG), was designed as a cytotoxic agent that preferentially targets lymphoid cells. Our objective was to characterize the antiproliferative activity, pharmacokinetics, pharmacodynamics, and safety of GS-9219. EXPERIMENTAL DESIGN GS-9219 was selected through screening in proliferation assays and t...
Reduction of glutamine synthetase (GS) function is closely related to established epilepsy, but little is known regarding its role in epileptogenesis. The present study aimed to elucidate the functional changes of GS in the brain and its involvement in epileptogenesis using the amygdala kindling model of epilepsy induced by daily electrical stimulation of basolateral amygdala in rats. Both expr...
Activating transcription factor-(ATF-) 3, a stress-inducible transcription factor, is rapidly upregulated under various stress conditions and plays an important role in inducing cancer cell apoptosis. NBM-TP-007-GS-002 (GS-002) is a Taiwanese propolin G (PPG) derivative. In this study, we examined the antitumor effects of GS-002 in human hepatoma Hep3B and HepG2 cells in vitro. First, we found ...
Insulin stimulates glycogen synthase (GS) through dephosphorylation of serine residues, and this effect is impaired in skeletal muscle from insulin-resistant [obese and type 2 diabetic (T2DM)] subjects. Exercise also increases GS activity, yet it is not known whether the ability of exercise to affect GS is impaired in insulin-resistant subjects. The objective of this study was to examine the ef...
It is aimed to evaluate Gallium-67 scintigraphy (GS) and CT for predicting clinical outcome in lymphoma patients who undergo autologous stem-cell transplantation (ASCT). Forty patients undergoing ASCT, had GS before and at 100 days post-transplantation (D-100). Patients were followed for 6-61 months and 15 had repeat GS at 200 days post-transplantation (D-200). All patients underwent computed t...
INTRODUCTION/BACKGROUND The increase of prostate cancer diagnosis after the introduction of prostate-specific antigen (PSA) screening resulted in overtreatment of patients with low risk tumors. The histological Gleason score (GS) revised in 2005 by the International Society of Urological Pathology (ISUP) is currently the most reliable tool to separate aggressive from indolent prostate cancer. ...
We conducted this double-blind, parallel-group, placebo-controlled, randomized, multiple-ascending-dose study to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of GS-9851 (formerly PSI-7851) in treatment-naïve patients infected with hepatitis C virus (HCV) genotype 1. Thirty-two patients received active doses up to 400 mg of GS-9851 once daily for 3 days. GS-9851 and th...
Selenium compounds like selenite (SeO3(2-) may form a covalent adduct with glutathione (GSH) in the form of selenodiglutathione (GS-Se-SG), which is assumed to be important in the metabolism of selenium. We have isolated GS-Se-SG and studied its reactions with NADPH and thioredoxin reductase from calf thymus or with thioredoxin reductase and thioredoxin from Escherichia coli. Incubation of 0.1 ...
