one of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (lm) andtransmission electron microscopy (tem). for the lm study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. sections were stained with orcein. for the tem stud...

Large-strain elastic superhydrophobicity is highly desirable for its enhanced use performance and functional reliability in mechanically dynamic environments, but remains challenging to develop. Here we have, for the first time, proven that an elastic fibrous membrane after surface hydrophobization can maintain superhydrophobicity during one-directional (uniaxial) stretching to a strain as high...

A microfluidic method is presented to measure the elastic membrane properties of a population of microcapsules with diameter of order 60 μm. The technique consists of flowing a suspension of capsules enclosed by a polymerized ovalbumin membrane through a square-section microfluidic channel with cross dimension comparable with the capsule mean diameter. The deformed profile and the velocity of a...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...

Thoracic aorta were elastic type, tunica intima consisted of a single layer of flattened endothelial cells, sub endothelial layer and indistinct internal elastic membrane. Tunica media is thickest among the three layers and welldefined elastic lamellae, they were separated by circularly arranged smooth muscle, collagen fibers and reticular fibers. External elastic membrane was not distinguishab...

Abstract We consider a linear system that consists of wave equation on horizontal hypersurface and parabolic in the half space below. The model describes longitudinal elastic waves organic monolayers at water–air interface, which is an experimental setup relevant for understanding propagation biological membranes. study scaling regime where length scale much larger than vertical provide rigorou...

a pvc-based membrane containing cerium phosphate was developed. unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. the response of molybdate selective electrode based on this membrane was perfectly linear in the concentratio...
