The body’s predominant choice of substrates and the rate their oxidation in working muscle are largely influenced by physical activity intensity. higher intensity work, more important role energy supply processes played carbohydrates. It is suggested that ability to most effectively use fat as an substrate at rest during exercise allows athletes save carbohydrates perform high-intensity work. T...

There is a general agreement (belief) that lipids are the pivotal element in inflammatory disease. One of the most studied topics is the connection between lipid oxidation and cardiovascular disease. In a very recent review, the introductory paragraphs states, after resuming the elements of the inflammatory response starting with stimulated endothelium displaying adhesive molecules for circulat...

Variables affecting the adherence of Gardnerella vaginalis to human vaginal epithelial cells were examined in vitro. Adherence depended on pH, with maximum attachment occurring between pH 5 and pH 6. Preincubation of the bacteria at 56 degrees C for 30 minutes and ultraviolet irradiation resulted in a noticeable decrease in adherence. In contrast, adherence was not altered by preincubating the ...

The kinetics of oxidation of polyvinyl alcohol, FH-17, with sodium hypochlorite has been studied. The effects of ~ buffer concentration, pH, initial oxidant concentration and temperature of reaction on the rate of reaction have been investigated. The experimental data indicate that the reaction is first order with respect to hypochlorite concentration. Additional data on change in the rate of r...

In a previous study, selective degradation of carbohydrates versus lignin in buried woods was demonstrated by non-destructive spectroscopy (C NMR) and destructive wet chemical methods (acid hydrolysis and alkaline CuO oxidation). In this paper, spruce, alder and oak woods deposited in coastal sediments and their recent equivalents are characterized by pyrolysis-mass spectrometry and pyrolysis-g...

Previous papers from this laboratory (King and Cheldelin, 1952, 1952a, 1954; Hauge et al., 1955, 1955a) have reported on the oxidation of carbohydrates in Acetobacter suboxydans. Neither resting nor disintegrated cells can oxidize acetate or other intermediates of the tricarboxylic acid cycle. These findings have recently been confirmed in another laboratory (Rao and Gunsalus, 1955). From the c...

Photosynthesis of green plants, algae and cyanobacteria is powered by sunlight. It uses water as ultimate donor of electrons for the reduction of CO2 to yield carbohydrates. Photosystem II (PS II), a water^ plastoquinone oxidoreductase, is the key enzyme of oxygenic photosynthesis. It is an integral protein of the thylakoid membrane. PS II is functionally bipartite, its photosynthetic reaction ...

LTHOUGH fumarase was discovered by Einheck1 in 1919 and has subsequently been found to have a wide biological distribution, there are no reports to our knowledge of its activity in separated human beukocvtes. Fitmarase is one of the essential enzymes that catalyze the oxidation of carbohydrates, fatty acids and some amino acids via the citric acid cycle. Specifically, fumarase mediates the esta...
