Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Water activities of a series of polyol/water systems were measured with an AquaLab dew point water activity meter at 298 K. The investigated polyols with carbon numbers from n=2−7 are all in liquid state at room temperature and miscible at any molar ratio...

1-Deoxyglucose (1,5-anhydroglucitol), a metabolite related to diabetes mellitus, was identified in human plasma by gas-liquid chromatography and by gas-liquid chromatography/mass spectrometry. Plasma polyols were accurately determined with a gas-liquid chromatograph equipped with an all-glass capillary column. The plasma content of 1-deoxyglucose in healthy persons varies with age. Although the...

CoSn(3) nanoparticles have been successfully assembled on noncovalently poly(diallyldimethylammonium chloride)-functionalized multiwalled carbon nanotubes (MWCNTs) via a chemical reduction method in a polyol system. The influences of the surface functionality and the reaction temperature on the synthesis of uniform CoSn(3)-MWCNTs nanohybrids have been investigated. The as-synthesized CoSn(3)-MW...

The single-step construction of various densely oxygenated carboskeletons was achieved by radical-based twoand three-component coupling reactions of sugar derivatives, without the need for light or heat. Et3B/ O2-mediated decarbonylation readily converted a-alkoxyacyl tellurides to a-alkoxy carbon radicals, which intermolecularly added to glyoxylic oxime ether or enones to provide the two-compo...

Palladium nanoparticles supported on multi-walled carbon nanotubes (Pd/MWCNTs) have been synthesized using a modified polyol reduction method and its performance in methanol oxidation reactions has evaluated. The morphology of palladium on MWCNTs was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic performance of synthesized catalyst ...

PURPOSE Dogs fed a diet containing 30% galactose experience retinal vascular changes similar to those in human diabetic retinopathy, with selective pericyte loss as an initial lesion. In the present study the relationship among reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent reductases, polyol formation, and flux through the polyol pathway in cultured dog retinal capillary...

BACKGROUND Peritoneal dialysis with glucose- and lactate-containing dialysis solutions stimulates peritoneal angiogenesis and fibrosis. These serious side effects can also be induced by chronic peritoneal exposure to dialysis solutions in nonuremic rats. The high glucose concentrations of the dialysis solutions may saturate physiological glucose metabolism pathways and stimulate the polyol path...

The present study was performed toevaluate the effect of aqueous-methanolic extract of Osbeckia chinensis roots, on the polyol pathway enzymes i.e., aldose reductase (AR) and sorbitol dehydrogenase (SDH) in normoglycemic and diabetic mice of two different age groups (sixand one-month old). Polyol pathway under hyperglycemic condition has been associated with the pathogenesis of diabetic complic...
