Previously, we reported that transgenic mice overexpressing endothelin-1 in astrocytes showed more severe neurological deficits and increased infarct after transient focal ischemia. In those studies, we also observed increased level of aldose reductase (AR), the first and rate-limiting enzyme of the polyol pathway, which has been implicated in osmotic and oxidative stress. To further understand...

Rats fed a 50% galactose diet were treated topically in one eye with 1% Sorbinil . The eye treated with Sorbinil remained clear during the following 4-week period. Unexpectedly, the lens of the untreated eye also maintained transparency. Histologically both lenses remained normal. Moreover, the reduced dulcitol levels in the lenses of both eyes were identical. These findings suggest that the ef...

BACKGROUND Erythritol is a polyol that is used in the food and beverage industry. Due to its non-caloric and non-cariogenic properties, the popularity of this sweetener is increasing. Large scale production of erythritol is currently based on conversion of glucose by selected fungi. In this study, we describe a biotechnological process to produce erythritol from light and CO2, using engineered ...

Levels of the C6-polyol mannitol were observed to rise dramatically in the biotrophic interaction of the rust fungus Uromyces fabae and its host plant Vicia faba. Mannitol was found in millimolar concentrations in extracts and apoplastic fluids of infected leaves and also in extracts of spores. We suggest that this polyol might have at least a dual function: first, as a carbohydrate storage com...

Diabetes is a disease, which has assumed vital public health importance because of the complications associated with it. Various mechanisms including polyol pathway along with a complex integrating paradigm have been implicated in glucose-mediated complications. Though polyol pathway was established as a major mechanism, precise pathogenesis of these complications is not yet completely elucidat...

We report cuboctahedral Pd nanoparticles on WC synthesized by the polyol process using ethylene glycol with NO(3)(-) and Fe(3+)/Fe(2+) ions. The cuboctahedral Pd/WC shows much improved electrocatalytic activity for methanol electrooxidation in alkaline solution.

Here, we introduce a polydixylitol based highly osmotic polymer that not only transmigrates the BBB by intra-arterial infusion of osmotic polyol but also triggers cellular uptake via modulation of caveolae mediated endocytosis.

Monomorphic Pt octapod and tripod nanocrystals have been successfully synthesized by an iron nitrate modified polyol process, in which iron nitrate has been proven to be vitally important for slowing down the reduction rate of Pt precursors.

Cultured Schwann cells under exposure to high glucose and methylglyoxal (MG) have been individually employed for studying diabetic neuropathy; however, similarities and differences between these two culture models have not been studied. We investigated the effects of high glucose and MG on viability, polyol pathway activity, and expression of oxidative stress markers (4-hydroxy-2-nonenal (4HNE)...

Nanoparticles of Ni carbide of about 50 nm in diameter were synthesized by the reduction of Ni salt in a polyol solution in the presence of polyvinylpyrrolidone (PVP). It was found that the aggregation of nanoparticles was suppressed when PVP was added to the polyol solution during synthesis. Diffraction peaks of the fcc and hexagonal structures were observed for the specimen synthesized withou...
