The ethanol, methanol and water extracts of Tecoma stans effective against tested for antiinflammatory activity, lipoxygenase, xanthine oxidase and acetycholinesterase inhibitory activity. The methanol, ethanol and water extracts showed in vitro anti-inflammatory activity by inhibiting the heat induced albumin denaturation is 86.32, 83.81, 61.39 g/ml and red blood cells membrane stabilization w...

Supported Pd clusters catalyze methanol oxidation to methyl formate with high turnover rates and >90% selectivity at near ambient temperatures (313 K). Metal clusters are much more reactive than PdO clusters and rates are inhibited by the reactant O(2). These data suggest that ensembles of Pd metal atoms on surfaces nearly saturated with chemisorbed oxygen are required for kinetically-relevant ...

Different surface sites of solid catalysts are usually quantified by dedicated chemisorption techniques from the adsorption capacity of probe molecules, assuming they specifically react with unique sites. In case of methanol synthesis catalysts, the Cu surface area is one of the crucial parameters in catalyst design and was for over 25 years commonly determined using diluted N2O. To disentangle...

Methanol is a highly toxic substance and acute methanol poisoning produces severe metabolic acidosis and serious neurological symptoms, including severe visual impairment, extrapyramidal signs and coma. We present three cases of accidental methanol intoxication and discuss the MRI findings.

The possibility to implement both the exhaustive dehydrogenation of aqueous methanol to hydrogen and CO2 and the reverse reaction, the hydrogenation of CO2 to methanol and water, may pave the way to a methanol based economy as part of a promising renewable energy system. Recently, homogeneous catalytic systems have been reported which are able to promote either one or the other of the two react...

According to the underlying concept of the rate-controlled constrained-equilibrium (RCCE) method, the relaxation of a complex reacting system towards the final equilibrium state is governed by a set of active and passive constraints imposed by the internal dynamics of the system that is considerably smaller in dimension than the original system. A set of 10 constraints, able to accurately model...

THE PURPOSE OF THIS INVESTIGATION was to determine whether methanol poisoning produces changes in the electroretinogram which follow a consistent pattern and are of diagnostic significance. The electroretinogram (ERG) is a graphic tracing of a mass response from the retina upon stimulation by light. The electroretinogram is of value in studying diseases of the retina and can be used as an objec...

The records of Forensic Medicine Council of Turkey Bursa Morgue Department reveal the first case of fatal methanol ingestion in a child. Household methanol exposures are mostly due to accidental ingestion of washing fluids. A 4 year-old girl was admitted to the emergency department with her parents with gastrointestinal symptoms; nausea, vomiting and abdominal pain. Toxicological studies reveal...
