Researchers found that a significant component of the muscle reaction in whiplash injuries arises from being startled by the abrupt motion and loud sound of impact. This new understanding may lead to improved prevention and management techniques for this common injury.
Researchers have found that gene-expression profiling can predict a lung cancer's prognosis, with tumors resembling early lung development having the worst prognosis. The study identifies key genes involved in biological pathways believed to be crucial in lung cancer development, offering potential targets for therapy.
Data from a survey of 43,000 U.S. adults suggest that early alcohol use is associated with an increased risk of developing future alcohol problems, including dependence and relapse.
A study of 9,125 adults found obesity associated with a 25% increased risk of mood and anxiety disorders, and a 25% decreased likeliness for substance abuse. Obesity was also linked to depression through mechanisms such as reduced physical activity and stigma.
