Sources of Information Utilized by Active Duty Service Members for Nutritional Supplement Safety and Efficacy.

Introduction: The increasing prevalence of nutritional supplement use in the United States, combined with the risk of adverse effects from these largely unregulated products, poses a significant challenge to health care professionals. The purpose of our study is to evaluate the use of nutritional supplements in an active duty military population, particularly those supplements with increased adverse effect profiles, and the sources of information that service members use to make decisions regarding the safety and efficacy of supplements.

Materials And Methods: The investigators distributed a voluntary, anonymous, self-report survey to a battalion of active duty service members to collect demographic data and information pertaining to the use of, adverse effects from, and sources of information utilized regarding the safety and efficacy of nutritional supplements.

Preparticipation Screening of Young Athletes: Identifying Cardiovascular Disease.

The most common cause of sudden cardiac death (SCD) in young athletes in the United States is "autopsy-negative sudden unexplained death." This makes it extremely difficult to screen for and diagnose predisposing cardiovascular conditions before athletic participation. The goal of the preparticipation physical examination is to detect risk factors for SCD, make risk-based decisions regarding the need for further workup, and ultimately recommend for or against participation.

TLC plates as a convenient platform for solvent-free reactions.

Solvent-free oxidative couplings of naphthols have been optimized by co-spotting catalysts and substrates directly on silica TLC plates and heating, followed by chromatography, staining, and qualitative visualization.

On the relative migratory aptitudes of carbon and heteroatoms in borate complexes. A surprising alpha-thia effect.

Dimethylsulfoxonium methylide reacts with dicyclohexyl alpha-thiophenylmethyl)methylborane via 1,2-alkyl migration and alkyldithiaborolane via 1,2-sulfur migration.

The boron-catalyzed polymerization of dimethylsulfoxonium methylide. A living polymethylene synthesis.

Trialkyl and aryl organoboranes catalyze the polymerization of dimethylsulfoxonium methylide (1). The product of the polymerization is a tris-polymethylene organoborane. Oxidation affords linear telechelic alpha-hydroxy polymethylene.
