Four commonly used moisturizers promoted skin cancers in mouse studies.
Mice are not men. But the unexpected finding suggests that these — and perhaps other products — may not be as safe as they're thought to be.
The moisturizers tested in the study were Dermabase, Dermovan (a wholesale-only product discontinued in 2006), Eucerin Original Moisturizing Cream, and Vanicream.
In a mouse model of sun-related skin cancer, frequent application of each product resulted in more skin tumors and faster tumor growth, says study leader Allan H

Dietary nutrient limitation (dietary restriction) is known to increase lifespan in a variety of organisms. Although the molecular events that couple dietary restriction to increased lifespan are not clear, studies of the model eukaryote Saccharomyces cerevisiae have implicated several nutrient-sensitive kinases, including the target of rapamycin complex 1 (TORC1), Sch9, protein kinase A (PKA) and Rim15. We have recently demonstrated that TORC1 activates Sch9 by direct phosphorylation. We now show that Sch9 inhibits Rim15 also by direct phosphorylation

More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study reported in the latest issue of European Journal of Cardiovascular Prevention and Rehabilitation.1 The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis

This large, prospective, observational study showed that Finnish smokers who consumed eight or more cups of coffee per day had a 23% lowered risk for cerebral infarction, whereas those who drank two or more cups of black tea daily had a 21% lowered risk for this type of stroke vs those who drank little or none of these beverages. The associations were independent of risk factors such as a history of coronary heart disease.
Their report is published in the June 2008 issue of Stroke

Cutting down on caffeine could help people with the most common form of diabetes better control their blood sugar levels, researchers said on Monday. Giving caffeine to a small group of people with type 2 diabetes caused their levels of the blood sugar glucose to rise through the day, especially after meals, researchers at Duke University Medical Center in Durham, North Carolina, found.

Despite such speedy-sounding names as "Full Throttle," "Amp" and "Rush," energy drinks pack a punch that is generally no stronger than coffee.

Habitual intake of caffeinated beverages provided protection against the risk of heart disease mortality among elderly participants in this prospective epidemiologic analysis.

Although fears that caffeine could lead to birth defects and miscarriage have largely been allayed in recent years, questions remained about whether it might be linked to birth weight and premature birth.
The latest study, reported Thursday in the online version of the British Medical Journal, is the first to attempt a controlled, randomized trial?athe gold standard of medical investigation.
For an individual woman, to reduce the risk of an adverse outcome, it's reasonable to limit caffeine to a modest amount.

That morning cup of coffee may be an antidote to post-exercise muscle soreness, if preliminary research is correct.
In a small study of female college students, researchers foundthat a caffeine supplement seemed to lessen the familiar muscle pain that crops up the day after a particularly challenging workout.
Known as delayed-onset muscle soreness, or DOMS, the pain is common in the day or two after a workout that was more intense than normal. Exercise that involves eccentric contraction of the muscles is particularly likely to cause delayed muscle pain.
