Neurotrophins use two types of receptors, the Trk tyrosine kinase receptors and the p75
neurotrophin receptor (p75NTR), to regulate the growth, development, survival and repair of …

For many years, placebos have been defined by their inert content and their use as controls
in clinical trials and treatments in clinical practice. Recent research shows that placebo …

Upon reaction with electrons, oxygen is transformed into reactive oxygen species (ROS). It
has long been known that ROS can destroy bacteria and destroy human cells, but research …

Background—Noninvasive assessment of diastolic filling by Doppler echocardiography
provides important information about left ventricular (LV) status in selected subsets of …

We describe here the isolation of stem cells from juvenile and adult rodent skin. These cells
derive from the dermis, and clones of individual cells can proliferate and differentiate in …

Polyatomic ions exhibit characteristic infrared spec-tra. Although such spectra are potentially
useful, there is very little reference to them in the recent literature. In particular, the literature …

Resilience and vulnerability represent two related yet different approaches to understanding
the response of systems and actors to change; to shocks and surprises, as well as slow …

To identify selective steps in metastasis, those that eliminate nonmetastatic tumor cells more
efficiently than metastatic cells, we have evaluated the sequential dissemination of tumor …

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) has limited treatment options;
long-term outcomes following intra-arterial radiation are unknown. We assessed clinical …

Converging lines of evidence implicate the beta‐amyloid peptide (Aβ) as causative in
Alzheimer's disease. We describe a novel class of compounds that reduce Aβ production by …
