PURPOSE To investigate whether a histologic link exists between osmotic fiber cell swelling and cortical tissue liquefaction in experimentally induced diabetic and galactosemic cataractogenesis of the rat lens. METHODS Confocal laser scanning microscopy, in conjunction with specific membrane labels and correlative transmission electron microscopy, was used to image large cortical areas with p...

Effects of the recycle solvent hydrotreatment on oil yield of direct coal liquefaction were carried out in the 0.18 t/day direct coal liquefaction bench support unit of National Engineering Laboratory for Direct Coal Liquefaction (China). Results showed that the hydrogen-donating ability of the hydrogenated recycle solvent improved and the hydrogen consumption of solvent hydrotreatment was incr...

In a double-blind randomized study, 30 mg/kg of methylprednisolone sodium succinate (MPN) or 15 mg/kg of mannitol placebo (PL) were infused in 28 patients after acute myocardial infarction. Measurements were obtained immediately before and after for 24 hours after the initial infusion. The partial pressure of oxygen at 50% saturation of hemoglobin (P50) did not change significantly in vitro or ...

Spectroscopy is a powerful technique to characterize single-walled carbon nanotubes (SWNTs). In particular, photoluminescence (PL) and the excitation spectroscopies have made a great advance in understanding the energy states and transition processes of excitons in SWNTs. The PL spectroscopy also has a potential to assign the chiral index (n,m) of a SWNT and to evaluate the abundance of (n,m) i...

The prosthetic leg (PL) is a typical human-machine system in which the dynamic interaction between the human body and PL (machine) determines a high requirement of ergonomics design for PL and consequently needs to consider an indicator of usability indicating the performance of gait biomechanics. How to evaluate the indexes of usability for PL products is critical to the design technology of P...

Monolithic phosphor-free two-color gallium nitride (GaN)-based white light emitting diodes (LED) have the potential to replace current phosphor-based GaN white LEDs due to their low cost and long life cycle. Unfortunately, the growth of high indium content indium gallium nitride (InGaN)/GaN quantum dot and reported LED's color rendering index (CRI) are still problematic. Here, we use flip-chip ...

peptic ulcer is one of the most prevalent gastrointestinal disorder, commonly occurs in developed countries. the present work was carried out to evaluate antiulcer effect of ipomoea batatas (l) dietary tuberous roots. the ethanolic extract of ipomoea batatas (eeib) was prepared by dynamic maceration for 7 days at room temperature using 70% ethanol (v/v). the antiulcer activity was evaluated by ...

Earthquake-induced soil liquefaction can generate excessive damage to building structures due significant reduction in effective stress. With increasing urbanisation and population growth, the performance of closely spaced buildings, such as those towns cities, is greater concern where structure–soil–structure interaction (SSSI) may occur conjunction with full or partial liquefaction. This stud...
