Muscle weakness seen in alcoholism linked to mitochondrial repair issues

Muscle weakness from long-term alcoholism may stem from an inability of mitochondria, the powerhouses of cells, to self-repair, according to a study funded by...

Alcohol’s role in traffic deaths vastly underreported: Study

It's no secret that drinking and driving can be a deadly mix. But the role of alcohol in U.S. traffic deaths may be substantially...

Nociceptin Good for What Ails the Stressed Brain

A team of researchers has published new findings on a system in the brain that naturally moderates the effects of stress. The findings confirm...

Why alcoholic’s gender matters

Although long-term chronic alcoholism ultimately destroys the bodies as well as the minds of men and women, it treats the genders differently. For one thing,...

Generic gabapentin may treat alcohol dependence

The generic anticonvulsant medication gabapentin shows promise as an effective treatment for alcohol dependence, based on the results of a 150-patient clinical trial of...

Potential of anti-stress peptide to block alcohol dependence

New research by scientists at the Scripps Research Institute has underlined the power of an endogenous anti-stress peptide in the brain to prevent and even reverse some of the cellular effects of acute alcohol and alcohol dependence in ...

University of Maryland School of Medicine study identifies genes associated with...

University of Maryland School of Medicine researchers have identified two genes associated with binge drinking that may open doors to new, more effective treatments for excessive alcohol drinking. The scientists found that manipulating two receptors...

Pretreatment increases liver transplant survival

Pretreating transplanted livers with the immune molecule interleukin-6 (IL-6) dramatically increased survival of rats receiving organs with fatty degeneration--a common condition in humans that typically reduces transplant viability. The results suggest a means of making it possible to use a higher percentage of available donor livers for transplantation in humans. With over three times as many Americans needing transplants as there are available donor livers, an effective approach to increasing the number of viable donor organs would help narrow the gap between demand and supply.

Alcohol researchers relate a genetic factor to anxiety in women

Researchers have identified a genetic factor that appears to influence anxiety in women. Combining DNA analysis, recordings of brain activity, and psychological tests, investigators at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) found that Caucasian and American Indian women with the same gene variant had similarly high scores on tests that measure anxiety. These women also had similar electroencephelograms (EEG) -- recordings of brain electrical activity as unique as an individual's fingerprints -- that showed characteristics of anxious temperament, further strengthening the association of this shared genetic factor with anxiety. The study appears in the current issue of the journal Psychiatric Genetics.

Alcohol Researchers Identify a Genetic Basis of Pain Response

A common genetic variant influences individual responses and adaptation to pain and other stressful stimuli and may underlie vulnerability to many psychiatric and other complex diseases, reports David Goldman, M.D., Chief, Laboratory of Neurogenetics, National Institute on Alcohol Abuse and Alcoholism, and colleagues at NIAAA and the University of Michigan. COMT val158met Genotype Affects m-Opioid Neurotransmitter Responses to a Pain Stressor appears in the February 21 issue of Science.
