## Abstract Automated sampling device was designed to permit determination of rates of biological transport of metabolites into cells. The substrate was automatically introduced into a stirred cell suspension at 37°C. The first sample was automatically taken after a mixing interval of 1 sec and nin

There are competing theories on the effects of parental involvement and control on adolescent development. Each theory holds implications for parents, adolescents, and counselors working with parents and adolescents. Using a national data set, this study sought to support or disconfirm theory and re

This article is a comparative review of career development programs in Switzerland and the United States, with emphasis on the degree of parental involvement. Investigators visited schools and interviewed parents in both countries. This article offers ideas for improving the effectiveness of career

The antigenic relationship of the egg jelly coat glycoproteins from Bufo japonicus japonicus and Xenopus laevis laevis was investigated using agar double diffusion methods. The presence of ligands in the jelly coats for the cortical granule lectin from X.l. laevis eggs was also investigated. Anti-je

Human bone marrow stromal cells repond to stimulation by the monokines IL-1 and TNF by producing colony-stimulating factors such as GM-CSF and G-CSF. In this study we show that I L -l a and TNFa act synergistically to stimulate GM-CSF and G-CSF production by cultured marrow stromal cells. We further

This study used data from a national sample of U.S. high school seniors to investigate the relationship of religious perceptions and behavior to several school, career, and leisure variables. Seniors positive perceptions of religion and frequent attendance at religious services were related to posit

This study examined how background and high school variables affected participants in either realizing their potential by completing a bachelor's degree or experiencing lost talent by not completing a bachelor's degree. A sample of participants who had demonstrated above average cognitive ability an

Phagocytosis requires the internalization of a significant fraction of the plasma membrane and results in the intracellular deposition of large particles. We evaluated the effect of phagocytosis on the cellular distribution of recycling receptors and uptake of ligand to determine whether phagocytosi

## Antiestradiol antibody immobilized on a polymer film is set in competition for tritium-labeled estradiol with estradiol receptor or antiestradiol antibody in solution. Measurement of equilibrium quantity of radiolabel in test solutions in the presence and in the absence of dissolved antibody or

Rich mixtures of the three fuels peffluoroethane, perfluoropmpane, and perfluorocyclobutane have been burned with fluorine singly, in pairs, and all together. Starting with stoichiometric mixtures, the fluorine concentration was reduced until the mixtures would no longer burn. Reaction products were
