Nanoparticles found near plaque-filled arteries

Scientific evidence increasingly links arterial calcification to the presence of nanosized particles so small that some scientists question whether a nanoparticle can live and, if so, play a viable role in causing disease.

RNA analysis can identify rejection in lung transplant patients

Recent data from the Lung Allograft Rejection Gene expression Observational (LARGO) study provides compelling evidence that profiling gene expression in peripheral blood can detect organ rejection in lung transplant patients.

Identifying cardiorespiratory neurocircuitry involved in central command during exercise in humans

For almost one hundred years the brain's ,central command, system , whose charge includes controlling the body's cardiorespiratory response to exercise , has been pursued. Animal experiments and functional imaging studies have provided clues to the location of this system, but the underlying electrophysiological activity has never been measured.

Scientists discover pathway that promotes muscle cell survival in mice

Scientists at the Salk Institute for Biological Studies have identified an enzyme that pumps up a cell's ability to maintain healthy muscle and restores normal muscle function in genetically engineered mice with weak muscles.

The convergence of embryonic and cancer signaling pathways: role in tumor cell plasticity

In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells.

Genetic risk for early death in rheumatoid arthritis

A chronic autoimmune disease, rheumatoid arthritis (RA) is marked by inflammation that takes a progressive toll on not only the joints, but also various organs and the whole body.

Researchers identify antioxidant mechanisms involved in protection against heart disease

Zvonimir Katusic, M.D., Ph.D., and Mayo colleagues have identified antioxidant mechanisms essential for regenerative function of endothelial progenitor cells (EPCs).

Lipocalin-2 protein may hold key to decreasing organ dysfunction rates in heart transplants

A new study, led by Felix Aigner, M.D., has identified a protein known as Lipocalin-2 (Lcn-2) as potentially responsible for regulating the body's inflammatory response during heart transplants.

FDA approves INVEGA treatment for schizophrenia

The U.S. Food and Drug Administration (FDA) has approved INVEGA (paliperidone) Extended-Release Tablets, a new once-daily, atypical antipsychotic, for the long-term maintenance treatment of schizophrenia.

Exercise pill switches on master regulator that controls the ability of cells to burn fat

By giving ordinary adult mice a drug - a synthetic designed to mimic fat - Salk Institute scientist Dr. Ronald M. Evans is now able to chemically switch on PPAR-d, the master regulator that controls the ability of cells to burn fat.

Oxytocin affects the heart's response to social isolation

A team of researchers investigating the effects of oxytocin, a peptide produced by the brain that regulates social behavior, has found that it can prevent detrimental cardiac responses in adult female animals exposed to social isolation.

Aspirin appears to be less effective heart treatment for women than men

A new study shows that aspirin therapy for coronary artery disease is four times more likely to be ineffective in women compared to men with the same medical history.

Small amounts of stem/progenitor cells from bone marrow enhance repair of damaged tissues

New studies in the laboratory of Dr. Darwin J. Prockop, Director of Tulane University's Center for Gene Therapy, are shedding light on the previously mysterious mechanism through which even relatively small amounts of stem/progenitor cells taken from a patient's own bone marrow enhance repair of damaged tissues.

Headaches may act like tiny transient strokes

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.
