The solubility of disodium terephthalate in aqueous sodium hydroxide and hydroxide–ethylene glycol mixtures was determined experimentally by temperature analysis, gravimetry titration. experimental results were compared with existing literature data the phase diagrams from −25 to 70 °C. has no considerable dependence on temperature. freezing points solutions vary composition like any other solu...

A presumptive diagnosis of secondary ethylene glycol toxicity in a female Turkey vulture (Cathartes aura) was made depending on the histopathological changes found in the renal tubules and presence of Isospora spp. of non-avian type within the colon. To the best of our knowledge, this is the first reported case of possible secondary ethylene glycol toxicity in a Turkey vulture in Louisiana Stat...

Crystals of human oxyhaemoglobin were obtained from poly(ethylene glycol) solutions. Spectroscopic and spectrophotometric measurements on the solutions during crystallization and on the dissolved crystals indicate that the method yields stable crystals of oxyhaemoglobin. Preliminary X-ray studies showed that the crystals obtained are isomorphous with those of deoxyhaemoglobin obtained from poly...

Objectives We aimed to develop a sustained release system for an anti-TNFa drug in treatment of chronic inflammatory arthritis. A novel form of intra-articularly injectable etanercept (ETN) loaded poly(ε-caprolactone) (PCL) or methoxy poly(ethylene glycol)-poly(ε-caprolactone)methoxy poly(ethylene glycol) (MPEG-PCL-MPEG) microspheres (patent pending) were prepared to provide long term controlle...

We studied the effectiveness of glycerol or ethylene glycol in preventing the increase in alkaline phosphatase activity of lyophilized or refrigerated quality-control serum after reconstitution or repeated freezing and thawing. Control serum reconstituted completely from the lyophilized state with subsequent storage at -20 degrees C showed a considerable decrease in alkaline phosphatase activit...

Interpolymer complexation is associated with the formation of hydrogen bonds between pendent and/or grafted groups of a single polymer or copolymers. The degree of complexation can be described theoretically in terms of complexation/decomplexation equilibrium characteristics. Graft copolymer networks of poly(methacrylic acid-g-ethylene glycol) were prepared by free radical solution polymerizati...

Herein we report the design of a photocurable amphiphilic co-network consisting of perfluoropolyether and poly(ethylene glycol) segments that display outstanding nonfouling characteristics with respect to spores of green fouling alga Ulva when cured under high humidity conditions. The analysis of contact angle hysteresis revealed that the poly(ethylene glycol) density at the surface was enhance...

Methods to break down hemicellulose contained in biomass into simple 5-carbon sugars are well documented. This invention comprises an enzymatic reaction scheme to convert the simple sugars (e.g., xylose, arabinose, etc.) to ethylene glycol in three stages. First, the sugar is cleaved enzymatically into glycolaldehyde and dihydroxyacetone phosphate. Second, dihydroxyacetone -a byproduct from the...

XC-72 carbon supported Pt catalyst was prepared by using a microwave heated ethylene glycol method and characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). For comparison, the same Pt/XC72 catalyst was also prepared by conventional heated ethylene glycol method. TEM image showed that microwave synthesized Pt nanoparticles were uniformly dispersed on the surface o...

This study investigated the encapsulation of newt iris pigment epithelial cells (PECs), which have the ability to regenerate a lens by trans-differentiation in vivo, within a biodegradable hydrogel of oligo(poly(ethylene glycol) fumarate) crosslinked with poly(ethylene glycol)-diacrylate. Hydrogel beads of initial diameter of 1 mm were fabricated by a molding technique. The swelling ratio and d...
