Low-calorie diets can extend longevity, but new research is the first to show that calorie restriction influences the body’s circadian rhythms’ involvement with the aging process in cells.

Network of synthetic-lethal interactions connecting commonly mutated genes to potential drug targets.

This concept is called “synthetic lethality” because the drug is only lethal

Normal cells help corral tumors (left) and when removed lead to expansion of cancers.

When Yale researchers took a closer look at skin cells, they discovered the unaffected neighbor

“The sleep of many parents is often disrupted by external sources such as a crying baby demanding care during the night. Doctors on call, who may receive several phone calls a night, also experience disruptions,” said Prof. Sadeh. “These night wakings could be relatively short — only five to ten minutes — but they disrupt

“It’s critical that adults aim for seven to nine hours of sleep each night to receive the health benefits of sleep, but this is especially true for those battling a chronic condition,” said Dr. M.

Lack of sleep and obesity have been associated with an increased risk of cardiovascular and metabolic diseases.

However, the association is not as clear in adolescents, an

The prevalence of prescription opioids increased from 0.9 percent during 1995-1999 to 5.2 percent during 2010-2015 in male drivers, and from 1.4 percent to 7.3 percent in female drivers.

Rather than thinking of these disorders as separate, individual clinical problems, it might be best to consider the relationships between overfat, its various risks, and its associated downstream diseases as a spectrum or progression where the vicious cycle of overfat, insulin resistance and chronic inflammation lies at one end, (constituting the population with early measurable
