Electron impact and chemical ionization mass spectral analyses of methyl esters species of free mycolic acid fraction from Rhodococcus lentifragmentus
(Chemistry and Physics of Lipids, 1996-09-30) [Artigo]
The free mycolic acid fraction from Rhodococcus lentifragmentus was derivatized to methyl esters and further fractionated into saturated (F-0), monounsaturated (F-1) and diunsaturated (F-2) species using argentation-TLC. ...
The azomethine-H modified colorimetric method of boron determination at fertilizers.
(Eclética Química, 1996-01-01) [Artigo]
The present work studied the azomethine-H colorimetric method for boron determination to fertilizers analysis applications. The reagent azomethine-H needs lights conditions of reaction that, jointed to the big sensibility ...
Triiodothyronine mimics the effects of estrogen in breast cancer cell lines
(Journal of Steroid Biochemistry and Molecular Biology, 1996-11-01) [Artigo]
MCF-7 (estrogen receptor positive - ER(+)) and MDA-MB-231 (estrogen receptor negative - ER(-)) are human breast cancer cell lines which express functional thyroid hormone receptors (c-erb A alpha 1 and c-erb beta 1) as ...
The electrochemical cleavage of the nitrobenzoyl group from butyl nitrobenzoates in N,N-dimethylformamide
(Journal of Electroanalytical Chemistry, 1996-10-30) [Artigo]
The applicability of the nitrobenzoyl group [NO2C6H4CO-] to protecting the functional hydroxyl group was investigated through study of the electrochemical behaviour of the butyl 4-, 3- and 2-nitrobenzoate compounds. These ...
