Best weight-loss plans for heart health

Over the past three decades, the rising obesity epidemic has been accompanied by a proliferation of weight-loss plans. However, as a new study by researchers from the University of Massachusetts Medical School (UMMS) reveals, these weight-loss plans vary significantly in their ability to positively affect heart health.

Ostructive sleep apnea and continuous positive airway pressure

Researchers in Brazil have found that treating patients who suffer from obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) dramatically reduces early indications of atherosclerosis in just months, linking OSA directly to the hardening or narrowing of the arteries.

Two genes in mammalian cells act as gatekeepers for cellular longevity

In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive.

Chronic infection persists by targeting stromal cell network in lymphoid organs

One of the biggest challenges to treating infectious diseases and developing preventive vaccines is the ability of many chronic infections to suppress the immune T-cell response over time.

Study suggests brain tumors need treatment with multiple 'targeted' drugs

Researchers at Dana-Farber Cancer Institute have shown that several, rather than just one, cell-growth switches are simultaneously overactive in many brain tumors and other solid tumors, explaining why treatment with just a single "targeted" switch-blocking drug often yields disappointing results.
