This paper explores autonomic approaches for optimizing provisioning for heterogeneous workloads on enterprise Grids and clouds. Specifically, this paper presents a decentralized, robust online clustering approach that addresses the distributed nature of these environments, and can be used to detect patterns and trends, and use this information to optimize(More)
Earlier research on rats with normal insulin sensitivity demonstrated that acute exercise increased insulin-stimulated glucose uptake (GU) concomitant with greater phosphorylation of Akt substrate of 160 kDa (pAS160). Because mechanisms for exercise effects on GU in insulin-resistant muscle are unknown, our primary objective was to assess insulin-stimulated(More)
Moderate calorie restriction (CR) (∼60% of ad libitum, AL, intake) has been associated with numerous favorable physiological outcomes in many species, and the insulin/IGF-1 and mTOR signaling pathways have each been proposed as potential mediators for many of CR's bioeffects. However, few studies have assessed the widely held idea that CR induces the(More)
Calorie restriction (CR) induces enhanced insulin-stimulated glucose uptake in fast-twitch (type II) muscle from old rats, but the effect of CR on slow-twitch (type I) muscle from old rats is unknown. The purpose of this study was to assess insulin-stimulated glucose uptake and phosphorylation of key insulin signaling proteins in isolated epitrochlearis(More)
Akt is a serine/threonine kinase that plays a key role in numerous cellular functions including metabolism, growth, protein synthesis, apoptosis, and cell proliferation. The most consistent and robust effect of moderate calorie restriction (CR; ~60% of ad libitum, AL, food consumption) on insulin signaling in rodent muscle has been enhanced insulin-induced(More)
BACKGROUND The possibility of impaired antioxidant status and so increased oxidative damage in periodontal disease is being conjectured. The present randomized controlled study was carried out with the objective of analyzing the activity of superoxide dismutase enzyme and thiol antioxidants in gingival crevicular fluid (GCF) and saliva as indicators of(More)
A simple, specific and sensitive LC-MS/MS assay for simultaneous determination of simvastatin (SV) and its active beta-hydroxy acid metabolite, simvastatin acid (SVA) in human plasma was developed using a statin analog as internal standard (IS). The method was validated over a dynamic linear range of 0.20-100.00 ng/mL for SV and 0.10-50.00 ng/mL for SVA(More)
BACKGROUND Chronic hypertension leads to cardiac hypertrophy, heart failure, and premature death. Little is known about the impact of dietary macronutrient composition on hypertension-induced cardiac hypertrophy and mortality. We investigated the effects of consuming either a high complex carbohydrate diet, a high simple sugar diet, or a high fat diet on(More)
A rapid, sensitive and accurate liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay for the simultaneous determination of tramadol and its active metabolite, O-desmethyltramadol in human plasma is developed using propranolol as internal standard (IS). The analytes and IS were extracted from 200 microL aliquots of human plasma via protein(More)
