Surface modification enables fiber lubrication and processing but little is known about the extent and dynamics of adsorption of typical adsorbates applied for such purposes, which often includes water-soluble block nonionic amphiphilic polymers. In this work we used quartz crystal microgravimetry (QCM) to investigate the adsorption on poly(ethylene terephthalate) (PET) of polyalkyl glycol ethe...

We determined the complete genome sequence of Sphingopyxis macrogoltabida strain 203N, a polyethylene glycol degrader. Because the PacBio assembly (285× coverage) seemed to be full of nucleotide-level mismatches, the Newbler assembly of MiSeq mate-pair and paired-end data was used for finishing and the PacBio assembly was used as a reference. The PacBio assembly carried 414 nucleotide mismatche...

Ethylene glycol ingestion, accidental or intentional, can be a life-threatening emergency. Assays are not available from most clinical laboratories, and, thus, results often require many hours or days to obtain. Enzymatic assays, adaptable to automated chemistry analyzers, have been evaluated, but they have been plagued by analytic problems. With an alternative method of data analysis applied t...

Tocopherol represents a big challenge for transdermal permeation owing to its extreme hydrophobicity and large molecular mass. The aim of the present study was to develop alpha-tocopherol (T) topical formulations and evaluate their ex vivo and in vivo permeation. Franz diffusion cells were used for ex vivo permeation, and neonatal rats were used for in vivo permeation. Seven gel formulations an...

alcohol poisoning can result in metabolic acidosis, renal failure, blindness, central nervous system (CNS) injury, pulmonary edema, or death. Ethylene glycol is present in antifreeze solutions, deicing solutions, foam stabilizers, and chemical solvents. Methanol is a component of windshield-washing solutions, gas-line antifreeze solutions, solvents, and brake cleaners. Isopropanol is found in r...

True alcoholic fermentation of carbohydrates, brought about by the action of undamaged cells, is not limited to the enzyme systems present in yeasts. Among the several other systems of microorganisms which are known to effect this conversion are the Fusaria. Investigation has shown that the enzymatic degradation of carbohydrates by Fusaria does not stop with the production of ethyl alcohol and ...

Cloud points (CPs) of heptaoxyethylene dodecyl ether (C12E7) in the presence of varying concentrations of additives such as inorganic salts, alkanols, diols, glycols and their ethers, hydroptopes and short chain tetraalkylammonium salts are measured and the increase/decrease in CP is discussed. While inorganic anions decrease the CP due to the “salting out” (dehydration) effect and follow the H...

The aim of this study was to optimize hesperetin cream formulations by in vitro permeation study and evaluate topical whitening active effect and skin irritation by in vivo study. The results showed that the solubility of lipophilic compound of hesperetin was increased by short-chain alcohol including ethanol, glycerin, propylene glycol and polyethylene glycols 400 (PEG 400). PEG 400 showed str...

Glycols and ethoxy– propoxy–alcohols are fundamental chemicals in industry, with annual productions of millions tons, still manufactured many cases corrosive unrecoverable catalysts such as KOH, amines BF3•OEt2. Here we show that commercially available, inexpensive, non–toxic, solid recyclable nanotitania catalyzes the hydration alkoxylation epoxides, water primary secondary alcohols but not ph...

We have quantitated the production of thymine glycols in DNA following treatment of cultured human fibroblasts or DNA in solution with the carcinogen N-hydroxy-2-naphthylamine. Thymine glycols, detected by using a monoclonal antibody specific to this base damage, were produced in DNA in a dose dependent manner both in vitro and in vivo. Exposure of DNA to N-hydroxy-2-naphthylamine in the presen...
