Those phytochemicals ? natural plant-based compounds that give fruits and vegetables a reputation as healthy food ? could be unhealthy if consumed in high doses in dietary supplements, teas or other preparations, scientists in New Jersey have concluded after a review of studies on the topic.
Scientific evidence increasingly links arterial calcification to the presence of nanosized particles ?o so small that some scientists question whether a nanoparticle can live and, if so, play a viable role in causing disease.
A handful of pistachios may lower cholesterol and provide the antioxidants usually found in leafy green vegetables and brightly colored fruit, according to a team of researchers.
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.
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.
Increasing intake of antioxidant-rich cherries may help lower the risk of metabolic syndrome and cardiovascular disease, suggests a new study presented today at the Experimental Biology annual meeting.
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.
Zvonimir Katusic, M.D., Ph.D., and Mayo colleagues have identified antioxidant mechanisms essential for regenerative function of endothelial progenitor cells (EPCs).
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.
A new study shows that left ventricular (LV) diastolic function, which is often impaired by age or obesity, is also affected by smoking in the young and physically fit.
