Study shows how context dictates what we believe we see
Scientists at UCL (University College London) have found the link between what we expect to see, and what our brain tells us we actually saw. The study reveals that the context surrounding what we see is all important – sometimes overriding the evidence gathered by our eyes and even causing us to imagine things which aren’t really there.

Cocaine's effects on brain metabolism may contribute to abuse
UPTON, NY - Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's reward chemical once its signal is sent. Since cocaine blocks dopamine transporters from doing their recycling job, it leaves the feel-good chemical around to keep sending the pleasure signal. Now a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory suggests that cocaine's effects go beyond the dopamine system. In the study, cocaine had significant effects on brain metabolism, even in mice that lack the gene for dopamine transporters.

Daily alcohol use causes changes in sexual behavior, new study reveals
A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition. The research, which will be published on 2 January 2008 in the scientific journal PLoS ONE, resulted in four novel findings with broad importance for further addiction research. It is the first study to characterize the effects of chronic alcohol exposure in fruit flies. Physiological evidence supporting various theories about the effect of alcoholic drinks has been lacking, so our now having a suitable animal model makes it possible to conduct much-needed laboratory research on this issue, explains research-team-leader Kyung-An Han, associate professor of biology and a neuroscientist at Penn State. Information from this research can serve as a baseline for similar studies in other animals, including humans.

Innovative Brain Imaging Identify Brain Abnormalities In Borderline Personality Disorder
Innovative Brain Imaging Brings Into View Centers Linking Poor Impulse Control with Negative Emotion. Borderline personality disorder is a devastating mental illness that affects between 1 to 2 percent of Americans, causing untold disruption of patients' lives and relationships. Nevertheless, its underlying biology is not very well understood. Hallmarks of the illness include impulsivity, emotional instability, interpersonal difficulties, and a preponderance of negative emotions such as anger—all of which may encourage or be associated with substance abuse, self-destructive behaviors and even suicide.

Carbon monoxide test helps doctors determine patients' smoking status

But new research, presented at CHEST 2007, the 73rd annual international scientific assembly of the American College of Chest Physicians (ACCP), indicates that the device has another use— it can quickly, inexpensively, and noninvasively identify a person who smokes. The study argues that if smokers know their blood CO levels, they may be more prone to quit or more likely to never start in the first place.

Mixing large doses of both acetaminophen painkiller and caffeine may increase risk of liver damage
WASHINGTON, Sept. 26 2007 -- Consuming large amounts of caffeine while taking acetaminophen, one of the most widely used painkillers in the United States, could potentially cause liver damage, according to a preliminary laboratory study reported in the Oct. 15 print issue of ACS’ Chemical Research in Toxicology, a monthly journal. The toxic interaction could occur not only from drinking caffeinated beverages while taking the painkiller but also from using large amounts of medications that intentionally combine caffeine and acetaminophen for the treatment of migraine headaches, menstrual discomfort and other conditions, the researchers say.

Family history of alcoholism affects response to drug used to treat heavy drinking
Philadelphia, PA, September 19, 2007 – Naltrexone is one of four oral medications approved by the U.S. Food and Drug Administration (FDA) for the treatment of alcoholism. A recent large multicenter research study of alcohol dependence supported by the National Institute of Alcoholism and Alcohol Abuse (NIAAA), the COMBINE Study, suggested that naltrexone produced a modest but significant benefit but another FDA-approved medication, acamprosate, was ineffective. Perhaps consistent with its modest effects in COMBINE, naltrexone is not widely prescribed in the treatment of alcoholism. Yet, clinicians report that naltrexone may have significant benefits for individual patients. To make naltrexone a more useful medication, it would be important to begin to identify groups of patients who might be more or less likely to show a significant clinical benefit from naltrexone prescription and to understand the causes of differential naltrexone efficacy. A new study that will appear in the September 15th issue of Biological Psychiatry suggests that alcohol dependent individuals with a family history of alcohol dependence may be more likely than alcohol dependent individuals without a family history of alcohol dependence to reduce their drinking in the laboratory when prescribed naltrexone.

New report on smoking shows who's quitting, who's not
Quitting smoking is not easy, but thousands of New Yorkers succeed at it every year. Who’s trying to kick the habit, and who’s succeeding In a new report titled Who’s Still Smoking, the Health Department sheds light on both questions. The report, based on a large survey of New York City adults, shows that two thirds of the city’s smokers – almost 800,000 adults – tried to quit in the past year, but only 17% of those succeeded. Data from the survey identify emotional distress and binge drinking as possible obstacles to quitting, and finds that less than a fifth of New York City smokers are using nicotine replacement therapy – even though it doubles the chances of success. The report is available online at http://www.nyc.gov/html/doh/downloads/pdf/survey/survey-2007smoking.pdf.
