Three adult rhesus monkeys were subjected to 2 and 24 hours of polymethylmethacrylate (PMMA) contact lens wear. The induced corneal changes were examined with the electron microscope. Mild epithelial oedema as well as early degenerative cell changes was present already after 2 hours' wear. Rigid lens wear for 24 hours produced more severe oedema and cell alterations together with premature cell...

Abstract Swelling of clay–sulfate rocks is a serious and devastating geo-hazard, often causing damage to geotechnical structures. Therefore, understanding underlying swelling processes crucial for the safe design, construction, maintenance infrastructure. Planning appropriate countermeasures problem requires thorough involved. We developed coupled hydro-mechanical (HM) model reproduce observed ...

Electrochemically induced mechanical degradation hinders the application of Si anodes in advanced lithium-ion batteries. Hollow structures and surface coatings have been often used to mitigate the degradation of Si-based anodes. However, the structural change and degradation mechanism during lithiation/delithiation of hollow Si structures with coatings remain unclear. Here, we combine in situ T...

Objectives: Carvedilol (CVD) is a nonselective β-adrenergic blocker that suffers from low absolute bioavailability (25-35%) due to first-pass metabolism. CVD-loaded buccal tablets were developed as a promising approach to overcome this limitation. Methods: The bilayers tablets were prepared by the direct compression technique. CVD-containing layer was based on one of four high molecular weight ...

Edemallschemia-reperfusion iajllrylLow-dose irradiation/Reactive oxygen species/Antioxidation function. We have reported that low-dose, unlike high-dose, irradiation enhanced antioxidation function and reduced oxidative damage. On the other hand, ischemia-reperfusion ajury is induced by reactive oxygen species, In this study, we examined the inhibitory effects of prior Iow-dose X-irradiatien on...

Some pathological conditions may affect osmolarity, which can impact cell, tissue, and organ volume. The hypothesis of this study is that changes in osmolarity affect the zero-stress state and mechanical properties of the aorta. To test this hypothesis, a segment of mouse abdominal aorta was cannulated in vivo and mechanically distended by perfusion of physiological salt (NaCl) solutions with g...

Humidity induced change in the refractive index and thickness of the polyethylene glycol (PEG) coatings are in situ investigated for a range from 10 to 95%, using an optical waveguide spectroscopic technique. It is experimentally demonstrated that, upon humidity change, the optical and swelling characteristics of the PEG coatings can be employed to build a plastic fibre optic humidity sensor. T...

Effects of guayule resin on mechanical, physical, and biological performance wood strand-based panels were evaluated. Southern yellow pine (Pinus spp. L) strands mixed with phenol formaldehyde (PF) to a target content 5% hot-pressed manufacture panels. A solution was prepared sprayed the immediately after PF different contents 0.5% 1.0%. Specimens cut from treated control subjected tensile, int...
