In this exploratory study, we examined undergraduates’ (N 1⁄4 298) knowledge of their university’s social media policies, understanding of free speech and privacy protections, opinions about university monitoring and discipline for personal social media posts, and perceptions of fairness regarding recent cases of student discipline for personal social media use. The results of our study indicat...

AIMS In vitro studies on hormone biological activities are commonly performed on cells cultured in nominally hormone-free media consisting of phenol-red-free media supplemented with charcoal-stripped (CS) serum. These media are largely used in almost all cell types, including endothelial cells (ECs). METHODS Cell number and metabolic activity were measured with standard methods. Angiogenesis ...

Murine macrophages incubated in metal-supplemented RPMI could block or promote oxidation of low-density lipoprotein (LDL) depending on the degree of metal supplementation. Only at high concentrations of Cu (1 micromol/L) and Fe (30 micromol/L) were cells prooxidant, leading to an accelerated rate of LDL oxidation over that measured in comparable cell-free media. At lower concentrations of Cu an...

In helically-cut strips of cerebral arteries isolated from dogs and monkeys, the addition of 1 mM iodoacetic acid (IAA) produced contractions during an early period (5 to 10 min) and also a prolonged exposure (50 to 70 min). The early contraction was abolished by exposure to Ca -free media containing EGTA, and significantly attenuated by treatment with procaine or dantrolene. Verapamil, lidocai...

UNLABELLED Chitosan is a biocompatible polysaccharide composed of glucosamine and N-acetylglucosamine. The polymer has a unique behavior of fluctuating between soluble chains at pH 6 and insoluble microparticles at pH 7. The purpose of this study was to test the hypothesis that chitosan structure, solubility state, and serum influence the rate of cell uptake. Chitosans with 80% and 95% degree o...

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...

This article explores the relationship between individuals’ media use during incarceration and their re-entry experience. Previous research suggests that mass media may facilitate the transition from prison to the free world because they can normalise life in the penitentiary and keep prisoners informed about major events and developments in society. The findings of a quantitative study into th...
