A method to measure the polyol pathway metabolic flux in the intact rabbit lens by 13C nuclear magnetic resonance spectroscopy is described. In the lens exposed to 35.5 mM glucose, the polyol pathway accounts for 1/3 of the total glucose turnover. The high metabolic activity of the pathway suggests a significant alteration in the reduced to oxidized pyridine nucleotide ratio in the lens exposed...

A combinative pretreatment technology of steam explosion (SE) and alkali was applied to enhance hydrogenolysis conversion of corn stalk into polyol with Ni-W2C or Fe-Mn-K catalyst. The results showed that treatments corn stalk with 0.4 MPa SE and alkali removed 84.16 wt% of hemicellulose and 71.83 wt% of lignin and thereby increased the cellulose content from 31.54 to 80.41 wt%. But the glucose...

Novel reactive polyols were synthesized via modification of castor oil, a renewable agricultural raw material with epoxy resin and triethylamine as a catalyst. This polyol was used for synthesis of polyurethane coating. Coating formulations were developed by reacting polyol with aromatic adduct, aliphatic adduct and castor oil based adduct in different NCO/OH ratio. All coating composition syst...

A monoclinic Li3V2(PO4)3/C (LVP/C) cathode for lithium battery applications was synthesized by a polyol-assisted pyro-synthesis. The polyol in the present synthesis acts not only as a solvent, reducing agent and a carbon source but also as a low-cost fuel that facilitates a combustion process combined with the release of ultrahigh exothermic energy useful for nucleation process. Subsequent anne...

Systematic studies of silver nanoparticle synthesis in a continuous-flow single-mode microwave reactor using polyol process were performed, revealing that the synthesis is exceptionally effective to give very small metal particles at full reaction yield and very high productivity. Inlet concentration of silver nitrate or silver acetate, applied as metal precursors, varied between 10 and 50 mM, ...

In a search for genes responsible for the accumulation of antimonite in Escherichia coli, TnphoA was used to create a pool of random insertional mutants, from which one antimonite-resistant mutant was isolated. Sequence analysis showed that the TnphoA insertion was located in the glpF gene, coding for the glycerol facilitator GlpF. The mutant was shown to be defective in polyol transport by Glp...

The recent identification of several additional members of the family of sugar transport facilitators (gene symbol SLC2A, protein symbol GLUT) has created a heterogeneous and, in part, confusing nomenclature. Therefore, this letter provides a summary of the family members and suggests a systematic nomenclature for SLC2A and GLUT symbols.

Acute kidney injury is associated with high mortality, especially in intensive care unit patients. The polyol pathway is a metabolic route able to convert glucose into fructose. Here we show the detrimental role of endogenous fructose production by the polyol pathway and its metabolism through fructokinase in the pathogenesis of ischaemic acute kidney injury (iAKI). Consistent with elevated uri...

Boron rejection by nanofiltration (NF) and reverse osmosis (RO) membranes in the presence of glycerol, mannitol and sorbitol was investigated as a function of feed solution pH and boron:polyol molar ratio. In the presence of polyols, significant boron rejection improvement was obtained and the extent of the impact was directly related to the stability constant of the boron-polyol complex. Polyo...
