Gas-chromatographic determination of phenols in aqueous samples after solid phase extraction
, 2022 S.654-65927 phenols including mono- di-, tri-, tetra- and pentachlorophenols, mono- and dinitrophenols, mono- and dinitrocresols and dimethylnitrophenols have been extracted from aqueous samples by solid phase extraction using both modified silica gel ...

ALTERATION BY DINITROCRESOL OF PATHWAYS FOR GLUCOSE OXIDATION IN EGGS OF ARBACIA PUNCTULATA [PDF]
The Journal of General Physiology, 1956 1. The C14O2 production by Arbacia eggs and embryos from glucose-1-C14, glucose-2-C14, and glucose-6-C14 has been measured without and with dinitrocresol in the incubation medium. In the absence of the dinitrocresol, the C14O2 production from glucose-1-C14 is more rapid than from glucose-2-C14 and much more rapid than from glucose-6-C14; this, together

DINITROCRESOL AND PHOSPHATE STIMULATION OF THE OXYGEN CONSUMPTION OF A CELL-FREE OXIDATIVE SYSTEM OBTAINED FROM SEA URCHIN EGGS [PDF]
Journal of General Physiology, 1949 1. A cell-free system capable of using oxygen with oxalacetate as substrate has been prepared from both unfertilized and fertilized sea urchin eggs. The oxygen uptake by this system is about twice that of an equivalent quantity of intact unfertilized eggs and half that of an equivalent quantity of intact fertilized eggs. 2.

Antagonistic Action of Dinitrothymol and Dinitrocresol on Cellular Respiration
Experimental Biology and Medicine, 1936 In an extensive study of the biological effects of nitro and dinitrophenols1 it was found that extremely small concentrations of 2,4-dinitrothymol (1-hydroxy, 3-methyl, 6-isopropyl, 2,4-dinitro-benzene) blocked the cell division of fertilized sea urchin (Arbacia punctulata) eggs without, in any concentration, giving more than a slight stimulation of ...

Glucose, Mannose, and Fructose Metabolism by Ascites Tumor Cells: Effects of Dinitrocresol
Experimental Biology and Medicine, 1954 Summary1. Ascites tumor cells derived from Ehrlich carcinoma or sarcoma 180 consume glucose, mannose, or fructose, but not galactose, xylose, or arabinose.

Experimental Biology and Medicine, 1958 SummaryConversion of glucose to lactate by ascites tumor cells derived from the Ehrlich carcinoma, Crocker sarcoma 180, and Freund sarcoma is stimulated by 4,6-dinitro-o-cresol under both aerobic and anaerobic conditions. Degree of stimulation increases as temperature is lowered from 37° to 15°, although the absolute rate of lactate production ...

Experimental Biology and Medicine, 1951 Summary1. In liver and brain there are two distinct mechanisms for phosphorylation, which may be separated by centrifligation of the tissue homogenates: (1) particulate elements dependent on oxidation of succinate or other substrates of the tricarboxylic acid cycle and (2) water-soluble or at least water-borne systems glycolyzing hexose diphosphate. In

Effect of Dinitrophenol and Dinitrocresol on Oxygen Consumption of Diapause and Developing Embryos.
Experimental Biology and Medicine, 1936 The stimulating action of the dinitrophenols on the oxygen consumption of cells and tissues is generally thought to reside in an acceleration of metabolic processes involving4 primarily the oxidation of carbohydrate. Dodds and Greville1 showed that the extra oxygen uptake induced by 4,6-dinitro-o-cresol (DNC) in kidney slices had a R.Q. of 1.

As the largest organ of the body, the skin performs multiple critical functions, such as serving as the primary barrier to the external environment. For this reason, the skin is often exposed to potentially hazardous agents, including chemicals, which ...
