Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...

OBJECTIVES The role of occupational exposures in hairy cell leukaemia was investigated through a multicentre, hospital based, case-control study. This paper analyses the role of exposure to solvents other than benzene in hairy cell leukaemia. METHODS The study included 226 male cases and 425 matched controls, exposure to solvents was evaluated by expert case by case review of the detailed dat...

alzheimer’s disease (ad) is a neurodegenerative disease that was characterized with deposit of beta amyloid (aβ) aggregate in senile plaque. oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. melissa officinalis is a medicinal plant from lamiaceae family, used traditionally in the treatment of cognitive disorders. it has cholinomimetic ...

Background: Organic acids refer to a family of compounds that are intermediates in a variety of metabolic pathways. Many organic acids are present in urine from clinically normal individuals. Elevated levels of urine organic acids cause to the organic acidurias, disorders in which some metabolic pathways in organic acid metabolism are blocked. The present work identified major and minor urinary...

The factors which distinguish molten salts from other non-aqueous solvents are described and the range of systems available outlined. Some illustrative examples of the various classes of reactions carried out in molten salts are then given. These include the exchange of halides and pseudohalides in organic and inorganic compounds, organic chlorinations, eliminations and rearrangements, a consid...

An amphiphilic electron-deficient (n-type) perylene diimide has been synthesized and characterized. The diimide contains a hydrophobic long chain on one end and a hydrophilic ethoxy chain on the other. The self-assembly of this molecule in polar and nonpolar solvents has been demonstrated by concentration- and temperature-dependent absorption and fluorescence spectroscopies. Analysis of the spe...

The global bio-based chemical market is growing in size and importance. Bio-based solvents such as glycerol and 2-methyltetrahydrofuran are often discussed as important introductions to the conventional repertoire of solvents. However adoption of new innovations by industry is typically slow. Therefore it might be anticipated that neoteric solvent systems (e.g., ionic liquids) will remain niche...

Chlorpyrifos is an solid organophosphorus pesticide widely used in agriculture. It relatively stable to hydrolysis neutral pH and acidic aqueous solutions. Stability decreases with increasing pH. practically insoluble water, but highly soluble most organic solvents such as acetone xylene methyl bromide. effective skin, stomach respiratory insecticide against aphids, spider mites, soil bugs hous...

The photostability of aromatic compounds in the presence of air is significantly improved through perfluoroalkylation of the corresponding aromatic cores and use of polyfluorinated solvents despite higher O(2) concentration in polyfluorinated solvents than in hydrocarbon solvents.
