Testosterone may help heart failure patients: Study

The researchers used testosterone patches and injections that improved the breathing and exercise abilities of people with heart failure, a chronic inability of the heart to pump enough blood to the rest of the body. Although most of the study participants were men, the researchers said the results would likely apply to women as well, through much smaller doses of testosterone.

Breast cancer cells that metastasize to the lung express higher level of PRDX2

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have shown that breast cancer cells that metastasize to the lung express a higher level of the protein peroxiredoxin 2 (PRDX2). The study suggests that the modulation of the levels of this protein could be a new therapeutic strategy to prevent lung metastases.

Reducing iron levels in blood plasma may protect brain from changes related to AD

Alzheimer's disease (AD) is now the sixth leading cause of death among Americans, affecting nearly 1 in 8 people over the age of 65. There is currently no treatment that alters the course of this disease. However, an increasing amount of evidence suggests that changes in the way the body handles iron and other metals like copper and zinc may start years before the onset of AD symptoms. A new study shows that reducing iron levels in blood plasma may protect the brain from changes related to AD.

Heart cells starved of nutrients less likely to be damaged during ischemia, reperfusion

Heart cells starved of nutrients are less likely to be damaged during periods of decreased blood flow and sudden influxes of blood, known as ischemia and reperfusion, and are also less likely to get out of synch with their cellular neighbors, the damaging phenomenon called arrhythmia.
