Five cationic porphyrins bearing one to four -N(CH(3))(3)(+) groups linked to the p-phenyl positions of 5,10,15,20-tetraphenylporphyrin (TPP) were synthesized in order to study the effect of overall charge and its distribution on the cellular uptake, phototoxicity and intracellular localization using

In the present study, a derivatization method for the determination of acidic herbicides has been investigated. This procedure involves the methylation with the quaternary ammonium salt trimethylanilinium hydroxide (TMAH) directly in the gas chromatographic auto-sampler vial for analysis by gas

The effects of two choline pivaloyl esters, [2-(2,2-dimethylpropionyloxy)ethyl]trimethylammonium iodide (1) and [2-(2,2-dimethylpropionyloxy)ethyl]trimethylammonium 2,2-dimethylpropionate (2), on learning and memory impairments induced in rats by scopolamine or lesions of nucleus basalis magnocellularis (NBM) have been evaluated by object recognition and Morris water

Cobalamin-dependent methionine synthase (MetH) catalyzes the transfer of methyl groups between methyltetrahydrofolate (CH(3)-H(4)folate) and homocysteine, with the enzyme-bound cobalamin serving as an intermediary in the methyl transfers. An MetH fragment comprising residues 2-649 contains modules that bind and activate CH(3)-H(4)folate

Our understanding of the perilymph kinetics of drugs depends largely on data obtained by the analysis of perilymph samples. Although a number of studies have demonstrated qualitatively that perilymph samples may be contaminated by cerebrospinal fluid (CSF), and some investigations
