Physical conditioning augments the fibrinolytic response to venous occlusion in healthy adults.
It is concluded that physical conditioning can enhance the augmentation of fibrinolytic activity that occurs in response to venous occlusion, which could be an important mechanism in the beneficial effect of habitual physical activity on the risk of cardiovascular disease.
The binding of RNA polymerase to DNA: stabilization by nucleoside triphosphates.
The presence of 4 nucleoside triphosphates increases the binding of polymerase to DNA and can protect the dissociation of polymer enzyme from its binding site by high salt concentration and can also protect polymerase from alteration by heat.
Stability of RNA polymerase--DNA complexes.
Molecular Aspects of Polyene- and Sterol-Dependent Pore Formation in Thin Lipid Membranes
The data are discussed with regard to the nature of the polyene-sterol interactions which result in pore formation, and the functional groups on amphotericin B responsible for membrane anion selectivity.
Quantitative studies on the sensitivity to complement lysis of red cells treated with thiol-reactive reagents.
The effect of reduced glutathione on the complement sensitivity of normal and paroxysmal nocturnal hemoglobinuria (PNH) red cells was determined quantitatively and GSH-treated normal cells differed from PNH cells in that the membrane acetylcholinesterase activity was normal and the cells were not stable during preparation and short-term storage.
Destruction of factor VIII procoagulant activity in tissue culture media.
The demonstration of protease activity in growth media of endothelial cell cultures leaves open the question of whether or not endothelial cells synthesize a molecule having all the biologic properties of the plasma FVIII/vWF protein.

The hypothesis that mononuclear cell support of erythropoiesis in the elderly is defective in elderly subjects is tested and data support the hypothesis.
Effect of Selenium Supplementation on Selenium Balance in the Dependent Elderly
Data support the concept that selenium nutritional status should be assessed not only by blood seenium content but also by selenia-dependent enzyme activity or selenum-dependent biologic effect.
