In this report it is shown that glycerol (0.5-10% v/v) stimulate the C12-E9-solubilized renal (Ca(2+)+Mg2+)ATPase in the presence of low concentrations of free Ca2+ (< 10(-6) M). At 4% (v/v), the polyol decreases the K0.5 for Ca2+ from 1.15 to 0.22 microM at the high-affinity site, and a very-high-affinity Ca2+ component appears. This component has a K0.5 < or = 10(-9) M and its maximal velocit...

Hyperalgesia to noxious stimuli is accompanied by increased spinal cyclooxygenase (COX)-2 protein in diabetic rats. The present studies were initiated to establish causality between increased spinal COX-2 activity and hyperalgesia during diabetes and to assess the potential involvement of polyol pathway activity in the pathogenesis of spinally mediated hyperalgesia. Rats with 1, 2, or 4 weeks o...

Pharmaceutical preparations usually contain preservatives and sweeteners. When parabens are used as preservatives and a polyol as a sweetener, a transesterification reaction may happen, yielding the transester polyol-paraben. The products formed in the transesterification reaction of methylparaben and sorbitol were analyzed by micellar electrokinetic chromatography and by HPLC. Up to six positi...

Transparent conducting electrodes (TCEs) are essential components in various optoelectronic devices such as solar cells, organic light emitting diodes, liquid crystal displays, touch screens, and smart windows. Nowadays, the most common conductive material used in TCEs is indium tin oxide (ITO). However, poor mechanical exibility, limited supply, high cost, and the vacuum forming process of th...

To manufacture high bio-content degradable polyurethane-coated fertilizer, the co-liquefaction of corn straw and starch was carried out to convert more biomass into bio-polyol so as substitute petroleum-based polyol. The effect ratio on liquefaction behavior mainly investigated by monitoring acid value, hydroxyl rate. Both chemical structures properties bio-polyols their coatings were character...

A simple and low-cost method to create metal-metal hybrid nanostructures possessing fairly regularly spaced "hot-spots" of surface plasmon resonances is proposed. The nanohybrid structure was prepared via self-assembly during a simple drop-casting procedure, using chemically synthesized silver nanowires and silver nanoparticles prepared in a single batch of a polyol process. Wide field illumina...

A green, one-step microwave-assisted polyol synthesis was employed to prepare blue luminescent carbon nitride dots (CNDs) using folic acid molecules as both carbon and nitrogen sources. The as-prepared CNDs had an average size of around 4.51 nm and could be well dispersed in water. Under excitation at 360 nm, the CNDs exhibited a strong blue luminescence and the quantum yield was estimated to b...

Two kinds of aqueous acrylic polyols (single step and multi step synthesis type) have been investigated for their performance in the two-component aqueous polyurethane application, by using more selective catalysts. The aliphatic polyfunctional isocyanates based on hexamethylen diisocyanates have been employed as suitable hardeners. The complex of zirconium, commercially known as K-KATXC-6212, ...
