Dehydroepiandrosterone (DHEA) is not a hormone but it is a very important prohormone
secreted in large amounts by the adrenals in humans and other primates, but not in lower …

Serum androgens as well as their precursors and metabolites decrease from the age of 30–
40 yr in women, thus suggesting that a more physiological hormone replacement therapy at …

Abstract The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the
neutrino mixing angle θ 13 with a significance of 5.2 standard deviations. Antineutrinos from …

Breast cancer is a major cause of death in Western women, with a 10% lifetime risk of the
disease. Most breast cancers are estrogen-dependent. Molecular therapies for breast …

Background: The epidemiology of staphylococcal colonization and community-associated
methicillin-resistant Staphylococcus aureus (MRSA) is changing, and little is known from the …

This study reports results of the 2-year follow-up phase of a randomized study comparing
outcomes of patients assigned to a nurse practitioner or a physician primary care practice. In …

17β-Hydroxysteroid dehydrogenase (17β-HSD) controls the last step in the formation of all
androgens and all estrogens. This crucial role of 17β-HSD is performed by at least five 17β …

We examined the intracellular transport of sterol in living cells using a naturally fluorescent
cholesterol analog, dehydroergosterol (DHE), which has been shown to mimic many of the …

The Daya Bay Reactor Neutrino Experiment is designed to determine precisely the neutrino
mixing angle θ13 with a sensitivity better than 0.01 in the parameter sin22θ13 at the 90 …

MATERIALS AND METHODS Setting and Sample. This study was part of a larger US
national patient safety study in which health care-associated infections in the ICU was an …
