Standing litter of emergent macrophytes often forms a major portion of the detrital mass in wetland habitats. Microbial assemblages inhabiting this detritus must adapt physiologically to daily fluctuations in temperature and water availability. We examined the effects of various environmental conditions on the concentrations of osmoregulatory solutes (polyols and trehalose) and the respiratory ...

Alcohols, phenols and carboxylic acids are silylated with very good yields in the presence of silyl methallylsulfinates under non-basic conditions and with the formation of volatile co-products.

The exaggerated flux through polyol pathway during diabetes is thought to be a major cause of lesions in the peripheral nerves. Here, we used aldose reductase (AR)-deficient (AR(-/-)) and AR inhibitor (ARI)-treated mice to further understand the in vivo role of polyol pathway in the pathogenesis of diabetic neuropathy. Under normal conditions, there were no obvious differences in the innervatio...

Diabetes causes increased oxidative stress, which is thought to play an important role in the pathogenesis of various diabetic complications. However, the source of the hyperglycemia-induced oxidative stress is not clear. It was found that the polyol pathway is the major contributor to oxidative stress in the lenses and nerves of diabetic mice. The first enzyme in the pathway, aldose reductase ...

Palladium is converted into palladium hydride, beta-PdH(x), in polyol solution using NaBH(4) as a hydrogen source; nanocrystalline Pd reacts to form PdH(x) faster and at lower temperatures than bulk Pd, and can be made to release hydrogen to regenerate Pd.

The aerobic oxidation of organic molecules and in particular alcohols bio-derived poly to value-added commodity is under continuous investigation, due the importance products (aldehydes, ketones carboxylic acids esters) challenging nature this chemical transformation, since rather harsh reaction conditions (T > 100 °C) are needed gain a significant substrate conversion [...]

Alterations in glucose metabolism have been implicated in the cardiovascular complications of diabetes. Previous work in this laboratory demonstrated that hearts from diabetic animals have an elevated cytosolic redox ratio (NADH/NAD+) and that this redox imbalance is probably due to elevated polyol pathway flux. We therefore hypothesized that 1) the elevated cytosolic redox ratio of diabetic he...
