introduction: renal ischemia reperfusion is considered to be one of the causes of acute renal failure (aki). in addition, renal ischemia is an important incident usually occurs due to renal transplantion, repair of suprarenal aneurysm, hemorrhagic shock. a recent study reported that reactive oxygen species (ros) are important mediators of aki. it seems essential to use antioxidant to decrease t...

Terminal renal failure is the final common fate of chronic nephropathies independent of the type of initial insult. The outstanding review by Brenner et al. (1) in 1982 introduced the idea that glomerular hemodynamic changes that develop as compensatory adaptation to irreversible nephron damage cause progressive deterioration of function and structure of the remaining nephrons. After reduction ...

We process one-dimensional (1D) NiO nanostructures in anodized alumina templates starting from electrochemically deposited Ni nanotubes (NTs), and characterize their morphology-dependent supercapacitance behavior. The morphology of the 1D NiO nanostructures is controlled by the time of annealing at 450°C. After 25 min of annealing, the NTs start to close but maintain the tubular structure, and ...

The limitations associated with traditional screw-based and cable-based deployment mechanisms for space deployable structures, such as stiffness, accuracy, distance, are effectively overcome by introducing the concept of a variable diameter internal drive device. To enhance stability during discontinuous surface transition phase inside tubular structure, thin-walled flexible beam structure is a...

In mammalian cardiac ventricular myocytes, Ca influx and release occur predominantly at t-tubules, ensuring synchronous Ca release throughout the cell. Heart failure is associated with disrupted t-tubule structure, but its effect on t-tubule function is less clear. We therefore investigated Ca influx and release at the t-tubules of ventricular myocytes isolated from rat hearts ~18weeks after co...

The evolution of structural motifs of gold cluster anions, Aun , in the size range n=11–24 has been determined through a comparison of electron diffraction data with density functional calculations. The results provide clear evidence for a transformation from planar to three-dimensional structures in the range n =12–14, the development of cage structures for n=16 and 17, the appearance of a tet...
