We conduct nonequilibrium molecular dynamics simulations to measure the shear stress sigma, the average inherent structure energy E{IS}, and the effective temperature T{eff} of a sheared model glass as a function of bath temperature T and shear strain rate gamma. For T above the glass transition temperature T0, the rheology approaches a Newtonian limit and T{eff}-->T as gamma-->0, while for T<T...

t-BHP induced oxidative stress and Ca2+ function impairment in fresh hepatocytes was studied in order to understand its role in cytotoxicity. Viability of hepatocytes by the release of lactate dehydrogenase and methyl thiazoletetrazolium reduction method alongwith malondialdehyde formation indicated oxidative stress in the hepatotoxic action of t-BHP.

Extending recent work on stress fluctuations in complex fluids and amorphous solids we describe general terms the ensemble average $$v(\Delta t)$$ standard deviation $$\delta v(\Delta of variance $$v[{\mathbf {x}}]$$ time series $${\mathbf {x}}$$ a stochastic process x(t) measured over finite sampling $$\Delta t$$ . Assuming stationary, Gaussian ergodic process, v$$ is given by functional v_{\m...

OBJECTIVE Lupus develops when genetically predisposed people encounter certain drugs or environmental agents causing oxidative stress such as infections and sun exposure, and then typically follows a chronic relapsing course with flares triggered by the exogenous stressors. Current evidence indicates that these environmental agents can trigger lupus flares by inhibiting the replication of DNA m...

Soil salinity and alkalinity adversely affects the productivity and grain quality of rice. The grain quality of 19 rice genotypes characterized as salt tolerant (T), semi-tolerant (ST) and sensitive (S) was assessed in lysimeters containing saline and highly alkaline soils. Head rice recovery was reduced by salinity stress whereas it was not affected by alkalinity stress. The ratio of length to...

Exposure to an open field is psychologically stressful and leads to an elevation in core temperature (T(c)). Methyl scopolamine (MS), a muscarinic antagonist, and pyridostigmine (PYR), a carbamate that inhibits acetylcholinesterase, do not cross the blood-brain barrier and have little effect on T(c) in resting, nonstressed animals. However, we have found that MS has an antipyretic effect on T(c...

abstract background: nurses face a great amount of stress that can threaten their health and reduce their motivation. nurses’ present working conditions lead to an increase in emotional pressures and depression. conducting a study on this seems to be necessary, with regard to nurses’ stressful working conditions, in order to take steps toward achieving different and non-meditational treatments ...
