An SDS-PAGE analysis of renal microsomal fraction of albino mice was performed to study the involvement of proteins in dexamethasone-induced type-2 diabetes mellitus (DM) and their alterations by metformin, a widely accepted oral antidiabetic drug. In addition, changes in renal lipid peroxidation (LPO), activities of superoxide dismutase (SOD) and catalase (CAT), reduced glutathione (GSH) conte...

AimStudy was undertaken to investigate the effect of altered behavioral condition like depression on various oxidative stress markers and biochemical parameters in rats. MethodsRats were subjected for short (21 days) and long term (84 days) social isolation; the rats displayed an increase in depression on force swim test relative to control. Various markers of oxidative stress like lipid per ox...

Municipal wastewaters are recognized as a major source of pharmaceutical and personal care products to the aquatic environment, thereby exposing biota to unknown chronic effects. This study sought to examine the immunotoxic effects of pharmaceutical and urban waste products on the freshwater mussel Elliptio complanata. Hemolymph samples were collected and treated in vitro with increasing concen...

The brain experiences structural, molecular and functional alterations during aging. In aging brain tissue, the oxidative stress increases due to decreased activity of antioxidant enzymes and increased oxidative stress leading to neurodegeneration associated with excitotoxicity. In the present study, we observed the effect of tachykinin neuropeptide Neurokinin B (NKB) and amyloid beta fragment ...

Changes in vascular conductance (VC) are required to counter changes in muscle perfusion pressure (MPP) to maintain muscle blood flow (MBF) during exercise. We investigated the recruitment of VC as a function of peak VC measured in three body positions at two different work rates to test the hypothesis that adaptations in VC compensated changes in MPP at low-power output (LPO), but not at high-...

The plasma or serum levels of various enzymes and components are known to increase in rats with water-immersion restraint stress (WIRS). We examined whether oxidative stress is involved in increases in the serum levels of various enzymes and components in rats with WIRS. Rats were exposed to WIRS for 6 h after oral administration of vitamin E (VE) (50 or 250 mg/kg). Rats with WIRS had increased...

The mechanism of suicidal inactivation of lactoperoxidase (LPO) by mercaptomethylimidazole (MMI) has been studied. Analogue studies indicate a specific requirement for the thiol group of MMI for inactivation of LPO in the presence of H2O2. MMI is oxidized via one-electron transfer by LPO compound II as demonstrated by a spectral shift from 430 to 412 nm through an isosbestic point at 421 nm. A ...

background: infertility is a problem concerning 10-15% of the individuals in the fertile period. this study investigated effects of proinflammatory factors as well as lipid hydroperoxides (lpo) levels upon in vitro fertilization (ivf) success. materials and methods: in this prospective, non-randomized, controlled clinical study, sera obtained from 26 fertile (group-1), 26 infertile women before...

We present here an algorithm for proving termination of term rewriting systems by gpo ordering constraint solving. Constraint solving is done eeciently thanks to an original shared term data structure based on SOUR graphs. We show how the algorithm works for proving termination of self-embedding rules like ffx ! fgfx. For particular cases of gpo like lpo, the algorithm is fully automatic. We gi...

BACKGROUND A Mediterranean diet has been associated with a reduced risk of cardiovascular disease and mortality. A possible mechanism is through a decrease in lipid peroxidation (LPO); however, evidence linking the Mediterranean diet with lower LPO in premenopausal women is sparse. OBJECTIVE We investigated whether adherence to a Mediterranean diet was associated with lower LPO concentrations...
