A persistent challenge in membrane biophysics has been to quantitatively predict how membrane physical properties change upon addition of new amphiphiles (e.g., lipids, alcohols, peptides, or proteins) in order to assess whether the changes are large enough to plausibly result in biological ramifications. Because of their roles as general anesthetics, n-alcohols are perhaps the best-studied amp...

Introduction: Neonatal hypernatremia dehydration (NHD) is a dangerous condition in neonates, which is accompanied by acute complications (renal failure, cerebral edema, and cerebral hemorrhage) and chronic complications (developmental delay). Children begin learning language from birth, and hearing impairment interferes with this process. We assessed the hearing status of infants with hypernatr...

Abstract Background Chiral furfuryl alcohols are important precursors for the synthesis of valuable functionalized pyranones such as rare sugar L-rednose. However, enantiopure chiral biobased remains scarce. In this work, we present a chemoenzymatic route toward nitrogen-containing ( R )- and S )-3-acetamido-5-(1-hydroxylethyl)furan (3A5HEF) from chitin-derived N-acetyl-D-glucosamine (NAG). Fin...

Crude cell-free preparations of Botrytis cinerea were found to oxidize straight-chain primary alcohols (except methanol), aromatic primary alcohols, and unsaturated primary alcohols. The resulting products were the corresponding aldehydes and an equal molar quantity of hydrogen peroxide.

Bioethanol is mixed with gasoline according to many countries' legislation pursuing environmental sustainability by reducing the use of fossil fuels. produced fermentation organic waste or biomass resources in diluted aqueous media. Unfortunately, bioethanol for fuel must have a low content water and its recovery an energy intensive operation. Heterogeneous azeotropic distillation (HAD) well-kn...

BACKGROUND An accurate assessment of the degree of dehydration in infants and children is important for proper decision-making and treatment. This emphasizes the need for laboratory tests to improve the accuracy of clinical assessment of dehydration. The aim of this study was to assess the relationship between clinical and laboratory parameters in the assessment of dehydration. METHODS We eva...

Aliphatic alcohols inhibited the activity of human matrix metalloproteinase 7 (matrilysin) competitively with K(i) of 6.1-19.4% (v/v) or 0.66-4.80 M. From the relationship between the structures of alcohols and their K(i) values, alcohols are considered to bind the hydrophobic S1' subsite most plausibly, and the size of the pocket was estimated to be large enough to accommodate the length of 1-...

Nanomagnetic NiFe2O4 was used as the efficient, stable, reusable catalyst for selective oxidation of alcohols to their corresponding carbonyl compounds using oxone (potassium hydrogen monopersulfate) as oxidant in the presence of water as solvent at room temperature. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained wi...

Nanomagnetic MgFe2O4 is an active, stable, and reusable catalyst for the oxidation of alcohols. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. The reactions were carried out in the presence of water as solvent and oxone (at room temperature) or H2O2 (at 60 ºC) as an oxidant. The catalyst was investigated...
