the current study conducted a finite element (fe) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. to examine the effects of the tcap process on the strain distribution and deformation behavior, fe simulations were employed. the fe results demonstrated that equ...

The processing of porous architectures based on Layered Double Hydroxides (LDH) is reviewed. Especially, a focus was put porosity in nm and μm ranges that can be prepared via various post-treatments templating techniques for the enhancement original properties. A challenge toward desired control structural ordering as well crystal growth LDH. present review paper mainly dedicated to summarizing...

OBJECTIVES/HYPOTHESIS Currently available silicone and metallic stents for tracheal stenosis are associated with problems of granulations, mucus trapping, and difficult removals. Our aim was to develop a novel bioabsorbable tracheal stent with mitomycin C (MMC) drug elution to circumvent such problems. STUDY DESIGN A randomized animal study. METHODS Twenty-five rabbits were randomly assigne...

A nonobstructing optical method was developed to measure proximal tubular fluid reabsorption in rat nephron at 0.25 Hz. The effects of uncaging luminal nitric oxide (NO) on proximal tubular reabsorption were investigated with this method. Proximal fluid reabsorption rate was calculated as the difference of tubular flow measured simultaneously at two locations (0.8-1.8 mm apart) along a convolut...
