Nonprescription drug use is increasingly prevalent in the United States. We report a case of a 31-year-old male who presented with hallucinations and was found to have rhabdomyolysis. He was consuming oxandrolone for six weeks and ingested methamphetamine the night prior to presentation. With supportive treatment, including intravenous hydration, the patient's mental status returned to baseline...

Slow earthquakes that occur at subduction zones are distinct from regular earthquakes in terms of their slip behavior. We consider this difference to relate to localized hydration reactions at the plate interface that influence the frictional properties. The results of laboratory friction experiments indicate that simulated serpentine faults are characterized by a low healing rate and large sli...

The non-thermal effects of microwave irradiation on enzyme-catalyzed reactions have been evaluated by keeping the reaction temperature constant during irradiation. Subtilisin-catalyzed transesterification and a-chymotrypsin-catalyzed esterification have been carried out in six solvents of differing polarities and at three different temperatures. In all cases, microwave irradiation was found to ...

In the recent years, the biophysical properties and presumed physiological role of aquaporins (AQPs) have been expanded to specialized cells where water and solute exchange are crucial traits. Complex but unique processes such as stomatal movement or pollen hydration and germination have been addressed not only by identifying the specific AQP involved but also by studying how these proteins int...

This report will concentrate on ions which are produced in nuclear power reactors and/or which are of special interest because of their small radius and/or their high charges, leading to hydrolysis. Mainly the results of Molecular Dynamics simulations will be discussed as they are able to provide a comprehensive and consistent description of the structural and dynamical properties of the water ...

The volume changes for the binding of various ligands to metmyoglobin and methemoglobin have been determined from the effect of pressure on the binding constants (for metmyoglobin) and by direct dilatometry (for methemoglobin). The volume changes associated with the binding of cyanide and azide ions to methemoglobin are pH-dependent. The volume change for the binding reaction is evidently affec...

Among the antimicrobial phytoalexins produced by Phaseolus vulgaris (French bean) are the prenylated isoflavonoids kievitone and phaseollidin. Two enzyme activities, kievitone hydratase and phaseollidin hydratase, occur in culture filtrates of the bean pathogen, Fusarium solani f. sp. phaseoli, and catalyse similar hydration reactions on the dimethylallyl moieties of the phytoalexins. The enzym...

A study was made on the effect of Ca, Sr, and Ba chloride complexes with dibenzo-18-crown-6 ether as catalysts process criteria efficiency industrial cumene oxidation using kinetic modeling. It is first stage in chain polymer composite production. The scheme classical reactions radical mechanism (reactions initiation, propagation, termination), molecular reactions, formation intermediate adduct...

Abstract Extrusion-based additive manufacturing imposes high requirements on the material stability right after extrusion. Therefore, a thorough understanding of chemical reactions that determine early reduction in processability is necessary. Accelerators are especially considered here, which have major influence reaction. This study contributes to these issues by analyzing 0.1 wt% TEA (trieth...

Sorption thermal heat storage is a promising solution to improve the development of renewable energies and promote rational use energy both for industry households. These systems store through physico-chemical sorption/desorption reactions that are also termed hydration/dehydration. Their introduction market requires assess their performances, usually analysed by numerical simulation overall sy...
