Preoperative Gleason score (GS) obtained from Trans Rectal Ultra Sonography (TRUS) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. But this method showed upgraded and downgraded results in comparison to Gleason score obtained from radical prostatectomy. The current study aimed to determine clinical or pathological v...

GS-9620 is an orally administered agonist of Toll-like receptor (TLR)7 currently being evaluated in clinical studies for the treatment of chronic HBV and HIV patients. GS-9620 has shown antiviral efficacy in preclinical models of chronic hepadnavirus infection in woodchuck as well as chimpanzee. However, the molecular determinants of GS-9620-dependent activation of TLR7 are not well defined. Th...

The analogue of cytidine, cytosine arabinoside (Ara-C), elicited a significant increase in the level of glutamine synthetase (GS) in embryonic chick neural retina in the absence of the steroid inducer of the enzyme . The increase was due to de novo synthesis of GS and was mediated by RNA which accumulated in the presence of the effective concentration of Ara-C . Accumulation of GS did not resul...

We investigated regulation of cardiac adenylate cyclase in 29-d-old BIO 14.6 Syrian hamsters, which inherit cardiomyopathy as an autosomal recessive trait. Pharmacologic stimulation of adenylate cyclase in cardiac membranes with isoproterenol, fluoride ion, guanine nucleotide, forskolin, and manganous ion indicated that there was defective coupling of the guanine nucleotide-binding protein that...

Five non-eddy-resolving oceanic general circulation models driven by atmospheric fluxes derived from the NCEP reanalysis are used to investigate the link between the Gulf Stream (GS) variability, the atmospheric circulation, and the Atlantic meridional overturning circulation (AMOC). Despite the limited model resolution, the temperature at the 200-m depth along the mean GS axis behaves similarl...

PURPOSE Hypothalamic hamartoma (HH) related epilepsy presents with gelastic seizures (GS), other seizure types and cognitive deterioration. Although seizure origin in GS has been well established, non-GS are poorly characterized. Their relationship with the HH and cognitive deterioration remains poorly understood. We analyzed seizure type, spread pattern in non-GS and their relationship with th...

Palygin OA, Pettus JM, Shibata EF. Regulation of caveolar cardiac sodium current by a single Gs histidine residue. Am J Physiol Heart Circ Physiol 294: H1693–H1699, 2008. First published February 8, 2008; doi:10.1152/ajpheart.01337.2007.—Cardiac sodium channels (voltage-gated Na channel subunit 1.5) reside in both the plasmalemma and membrane invaginations called caveolae. Opening of the caveol...

GS-9148 [(5-(6-amino-purin-9-yl)-4-fluoro-2,5-dihydro-furan-2-yloxymethyl)phosphonic acid] is a novel ribose-modified human immunodeficiency virus type 1 (HIV-1) nucleotide reverse transcriptase (RT) inhibitor (NRTI) selected from a series of nucleoside phosphonate analogs for its favorable in vitro biological properties including (i) a low potential for mitochondrial toxicity, (ii) a minimal c...

Gastrointestinal or cardiovascular complications limit nonsteroidal anti-inflammatory drugs (NSAID) prescription. Glucosamine hydrochloride (GS-HCl) alternatively chosen, but debates still exist in its clinical efficiency. COX-2 instability through inhibiting COX-2 N-glycosylation of GS-HCl raised the possibility of NSAID sparing effect. Study was done to determine whether combination treatment...

Glutamine synthetase (GS) plays an important role in nitrogen assimilation. The major GS of Mycobacterium tuberculosis is GlnA1, a type I GS whose activity is controlled by posttranscriptional modification by GlnE. GlnE is an adenylyl transferase comprised of an adenylylating domain and a deadenylylating domain which modulate GS activity. We previously demonstrated that GlnE is essential in M. ...
