BACKGROUND Obstructive nephropathy decreases renal blood flow (RBF) and glomerular filtration rate (GFR), causing tubular abnormalities, such as urinary concentrating defect, as well as increasing oxidative stress. This study aimed to evaluate the effects of N-acetylcysteine (NAC) on renal function, as well as on the protein expression of aquaporin 2 (AQP2) and endothelial nitric oxide synthase...

The relative magnitude of adjustment in osmotic potential (psi(s)) of water-stressed cotton (Gossypium hirsutum L.) leaves and roots was studied using plants raised in pots of sand and grown in a growth chamber. One and three water-stress preconditioning cycles were imposed by withholding water, and the subsequent adjustment in solute potential upon relief of the stress and complete rehydration...

 Common facilitators/reasons for disclosing are: trust in the recipient of disclosure; positive experiences with previous disclosure; existence of strong social support; to gain social support; to obtain stress relief form withholding a secret; obligation and duty to inform; self-acceptance of HIVpositive identity; to share knowledge; and to control disclosure (i.e. to disclose before someone ...

The prevention and control of stress relief gas have crucial influence on safety coal mine, it is not only the inevitable requirement safe production, but also an effective way to realize reasonable utilization gas. Taking 1103 working face Weijiadi mine as background, mining field was analysed by means numerical simulation, theoretical analysis practice, technology studied. results showed that...

Ultrasonic peening treatment (UPT) as a method of severe plastic deformation was used to treat cruciform welded joints of Q345 steel. The application of UPT achieves material surface nanocrystallization of the peening zone, reduces stress concentration, and produces residual compressive stresses at the welded toe. Micro-structure, hardness, stress relief, S-N curve, and the fatigue fracture mec...

Prosthetics soft tissue trauma is attacked with a combination of theoretical and experimental tools . A novel socket design results, accentuating flesh stress relief at the socket brim . Currently, the novel socket has been fitted to two subjects with long histories of stump trauma ; field test results are not yet available.

Several researchers have demonstrated that protein-bound polysacharide complexes such as PSK or PSP, derived from Coriolus versicolor ; or Lentinan derived from Letinula edodes are the most important component responsible for immunoenhancing and anti-tumour activities. In fact PSP is responsible for oxidative stress relief in cancer patients because it mimicks superoxide dismutase activity due ...

Although events associated with replication stress have long formed the cornerstone of checkpoint activation, questions remain about how cells maintain the integrity of replicating genomes. Now, Bermejo et al. (2011) identify a mechanism directly linking checkpoint function to the relief of topological tension at nuclear pore tethered genes.

Adaptor proteins participate in selective autophagy, which is critical for cellular detoxification and stress relief. However, new evidence supports an autophagy-independent key role of the adaptor p62 (encoded by the gene Sqstm1) in signaling functions central to tumor initiation in the epithelium and suppression of tumor progression in the stroma.
