The Se-dependent expression of two selenoproteins, cytosolic glutathione peroxidase (cGPx) and type I iodothyronine-5'-deiodinase (5'DI), was investigated in the porcine epithelial kidney cell line LLC-PK1 in serum-free medium. The selenite-dependent expression of cGPx and 5'DI was revealed by enzyme-activity measurements, affinity labelling of 5'DI, metabolic labelling of proteins with 75Se an...

in this paper, the reduced dierential transform method is investigated fora nonlinear partial dierential equation modeling nematic liquid crystals, itis called the hunter-saxton equation. the main advantage of this methodis that it can be applied directly to nonlinear dierential equations withoutrequiring linearization, discretization, or perturbation. it is a semi analytical-numerical metho...

n-Ribulose-l , 5-di-P carboxylase, purified from soybeans, had K, values of 0.13 XnM for COS and 0.19 mM for ribulose1,5-di-P under a Nz atmosphere. O2 inhibited 14C02 incorporation by the enzyme and this inhibition was rapidly reversed by Ns. Inhibition was competitive with respect to CO2 and uncompetitive with respect to ribulose-1,5-di-P. The Ki for O2 was 0.8 mM. This O2 inhibition, togethe...

Plants of the genus Taraxacum Wigg., have long been used as medicinal herbs. A phytochemical investigation of the aerial parts of Taraxacum bessarabicum (Hornem.) Hand.-Mazz. subsp. bessarabicum (Hornem.) Hand.-Mazz. (Asteraceae) yielded two coumarins [esculetin (1), cichoriin (2)], three flavonoids [ luteolin (3), luteolin 7-O-β-D-glucoside (4), gossypetin (5)] and six phenolic acids and their...

The effect of systemic administration of 16,16-dimethyl prostaglandin E2-methyl ester (di-M-PGE2) on the growth of B-16 melanoma tumors has been studied in C57BL/6J mice. Daily i.p. injection of 5 mu of di-M-PGE2 commencing on the day of tumor inoculation with 10(5) and 10(6) viable cells delayed appearance of tumors; for the smaller tumor inoculum, it also increased median survival among treat...
