Research finds that snake venom evolved only once in evolution, around 60 million years ago, and is now found in virtually all advanced snakes. A study of over 2,000 snakes from around the world has discovered that many non-venomous species possess complex venoms.
Researchers found that a compound blocking NPY activity delays alcohol self-administration and reduces rewarding effects of alcohol in mice. This study suggests L-152,804 has potential as a treatment for alcoholism.
A nationwide survey found that 56% of women with early stage breast cancer received less than 85% of their prescribed chemotherapy dose intensity. Treatment delays and dose reductions were common due to neutropenia, a shortage of infection-fighting white blood cells.
The genome sequence of Rhodopseudomonas palustris reveals its metabolic versatility, including ability to produce hydrogen and degrade toxic compounds. The bacteria's unique genetic capabilities make it a promising candidate for biotechnology applications, such as biofuel production.
A study found that behavioral anger contributes the most to alcohol-related aggression among men and women. Researchers examined healthy social drinkers and found that those with higher behavioral and cognitive anger scores were more likely to exhibit aggressive behavior when intoxicated. The findings suggest that understanding the rel...
A study found that individuals with high levels of social anxiety use alcohol more often to relieve social discomfort and avoid social situations without alcohol. They experience greater relief from anxiety in social situations, but not full relief, suggesting a self-medication strategy that may lead to increased risk of alcoholism.
A study found that individuals with co-existing alcoholism and antisocial personality disorder exhibit reduced responsiveness to aversive stimuli, including unpleasant photographs. This hyporesponsivity may facilitate maladaptive behavior and increase vulnerability to problems like criminality and substance abuse.
