More evidence on why the Mediterranean diet is good for heart

Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research.

High levels of prenatal smoking exposure affects sleep in early babies

A study in the Dec. 1 issue of the journal Sleep is the first to show that high levels of prenatal smoking exposure strongly modify sleep patterns in preterm neonates, which places infants at a higher risk for developmental difficulties that could persist throughout early and middle childhood.

Lactic acid found to be important energy source for tumor cells

Many tumors have cells that burn fuel for activities in different ways. Tumor cells near blood vessels have adequate oxygen sources and can either burn glucose like normal cells, or lactic acid (lactate). Tumor cells further from vessels are hypoxic and inefficiently burn a lot of glucose to keep going. In turn, they produce lactate as a waste product.

Drops in blood oxygen levels may be key to sudden death in some epilepsy patients

A new study by researchers at UC Davis Medical Center suggests that the sudden unexplained deaths of some epilepsy patients may be a result of their brains not telling their bodies to breathe during seizures.

Diuretic reduces risk for type of heart failure that affects women more often than

New research by The University of Texas School of Public Health shows that a medication for high blood pressure called a diuretic or water pill is particularly effective at reducing the risk for a type of heart failure that affects women more often than men.

Obstructive sleep apnea may be risk factor for sudden cardiac death

After studying the sleep characteristics of nearly 11,000 adults in an overnight sleep laboratory, Mayo Clinic researchers suggest that obstructive sleep apnea (OSA) - and, in particular, the low nighttime oxygen saturation of the blood it causes - may be a risk factor for sudden cardiac death (SCD).
