(20) Both surfactants were extensively degraded in vivo to yield a common metabolite, butyric acid 4-[35S]sulphate, the major urinary radioactive component.
Thiosulphate
Definition:
(n.) A salt of thiosulphuric acid; -- formerly called hyposulphite.
Example Sentences:
(1) Active sites for thiosulphate are probably strictly connected with cell membranes.
(2) Bacteria of the genus Thiobacillus can obtain energy from the chemolithotrophic oxidation of inorganic sulphur and its compounds (sulphide, thiosulphate and polythionates) and use this energy to support autotrophic growth on carbon dioxide.
(3) This effect may add to other factors decreasing sulphur availability in critically ill patients, and simultaneous administration of thiosulphate is therefore recommended to ensure a safe SNP treatment during and after coronary bypass operations.
(4) Some in vitro studies were performed to elucidate the action of S-adenosyl-L-methionine (SAM) and thiosulphate on liver rhodanese, delta-amino-levulinic acid dehydratase (Al A-D) and cytochrome oxidase affected by cyanide in the experimental conditions.
(5) Different bacterial cell fractions of Thiobacillus neapolitanus were examined in order to localize the active sites for thiosulphate and sulphite oxidation.
(6) The depression of the maximum responses to orciprenaline was reduced by the presence of sodium thiosulphate.
(7) At normal body temperature, as well as during hypothermia in cases receiving thiosulphate, the cyanide levels rose slowly but significantly with the infusion rate.
(8) The rate of ATP synthesis is higher in extracts of the cells grown in the dark under autotrophic conditions than in extracts of the cells cultivated in the light under anaerobic conditions or in the dark in the presence of thiosulphate and glucose.
(9) (35)S disappeared less rapidly from thiosulphate with ((35)S.SO(3))(2-) as substrate than with (S.(35)SO(3))(2-).
(10) Survival time of mice with 1 LD50 SM applied dermally was increased by GN and HR to a greater extent than by vitamin E or sodium thiosulphate probably due to one or more of the analgesic, anti-inflammatory, antihepatotoxic, antihistaminic, mast cell stabilization, lipid peroxidation inhibitory and free radical scavenging actions of the flavonoids.
(11) One mol of the enzyme formed 10 mol of thiocyanate per s from thiosulphate and cyanide.
