Green tea polyphenols counteract neurotoxic effects of sleep apnea

Researchers examined the effects of green tea polyphenols (GTP), administered through drinking water, on rats who were intermittently deprived of oxygen during 12-hour “night” cycles, mimicking the intermittent hypoxia (IH) that humans with obstructive sleep apnea experience. People with obstructive sleep apnea have been reported to have increased markers of oxidative stress and exhibit architectural […]

Hiring more nurses in hospitals likely to save lives

Health Behavior News Service – If hospitals added one more full-time registered nurse on staff to care for patients, the number of hospital-related deaths in the United States could decrease significantly, according to a new review. However, cost concerns and a worsening nursing shortage might make this an unlikely scenario. When asked how hospital administrators […]

High-fat meal before exercise enhances body fat loss

Newswise — Was something about the Atkins diet correct? Can eating fat actually enhance fat loss more than skipping a meal? Scientists report in the October 2007 issue of the Journal of Lipid Research that when either lean or obese individuals exercise after eating a high fat meal, their fats are broken down and oxidized […]

Higher flavonoid levels in organic tomatoes

Newswise — Levels of flavonoids increase over time in tomato crops grown in organically farmed fields, according to a rare long-term study scheduled for publication in the July 18, 2007 issue of ACS’s Journal of Agricultural and Food Chemistry, a bi-weekly publication. Other research has suggested that consumption of flavonoids may protect against cancer, heart […]

Dietary calcium beats calcium supplements for bone health

Washington University School of Medicine – Women who get most of their daily calcium from food have healthier bones than women whose calcium comes mainly from calcium supplement tablets, say medical researchers funded by the NIH. Surprisingly, this is true even though the calcium supplement users have higher average daily calcium intake. Adequate calcium is […]

Minimize glycation for healthy aging

Society for Experimental Biology – Protein degradation and malfunction is a major cause of ageing and can be the result of attacks on proteins by other molecules. One of these processes, called glycation, involves the spontaneous attack by sugars on proteins. If glycation gets out of hand, such as in diabetes, many proteins are degraded […]
