A novel 2'-modification, 2'-O-[2-(methylthio)ethyl] or 2'-O-MTE, has been incorporated into oligonucleotides and evaluated for properties relevant to antisense activity. The results were compared with the previously characterized 2'-O-[2-(methoxy)ethyl] 2'-O-MOE modification. As expected, the 2'-O-MTE modified oligonucleotides exhibited improved binding to human serum albumin compared to the 2'...

Ethylene glycol monoethyl ether (EGEE) can cause damage to testes and sperm, and its metabolites are believed to play an important role in its toxicity. Aldehyde dehydrogenase 2 (ALDH2) is involved in the metabolism of this chemical. To investigate whether and how the enzyme affects the toxicity of EGEE, we conducted experiments comparing Aldh2 knockout mice with wild-type mice. Administration ...

Data about hepatic effects of ethylene glycol ethers had been limited and inconsistent. In this study, we determined whether ethylene glycol monoethyl ether acetate (EGEEA) was a hepatotoxin in exposed workers. Workers from one silk-screening shop (n=29), using EGEEA as the major cleaning solvent, were recruited as high exposure group. Another group of workers with indirect and low exposure to ...

Ethylene glycol monoethyl ether (EGEE) is a solvent commonly used in industry. To find the health effect of the solvent exposure in women, we did an investigation on 32 female workers exposed to EGEE in factories manufacturing photopolymer sensitization plate, and 20 subjects working in the same companies without potential exposure to the solvent. The mean age was 35.0 and 33.9 yr in the two gr...

Alloy-based anodes have shown great potential to be applied in sodium-ion batteries (SIBs) due their high theoretical capacities, suitable working potential, and abundant earth reserves. However, practical applications are severely impeded by large volume expansion, unstable solid-electrolyte interfaces (SEI), sluggish reaction kinetics during cycling. Herein, a surface engineering of tin nanor...

Polyurethanes and polyurethane-ureas were prepared by the reaction of diethylene glycol and polyethylene glycol with excess of aromatic and aliphatic diisocyanate to yield isocyanate terminated prepolymers which were subsequently reacted with diols and diamines. These polymers were characterized by IR, 1HNMR spectra, viscosity measurements and thermogravimetric analysis.
