Smoking bans reduce the risk of heart attacks associated with secondhand smoke
WASHINGTON -- Smoking bans are effective at reducing the risk of heart attacks and heart disease associated with exposure to secondhand smoke, says a new report from the Institute of Medicine. The report also confirms there is sufficient evidence that breathing secondhand smoke boosts nonsmokers' risk for heart problems, adding that indirect evidence indicating that even relatively brief exposures could lead to a heart attack is compelling.

New reagents for genomic engineering of mouse models to understand human disease
The ability to specifically target and modify genes in the mouse allows researchers to use this small rodent to study how certain genes contribute to human disease. A common method used to make genetic changes in mice and cells is called site-specific recombination, where two DNA strands are exchanged. The two strands may contain very different sequences, but are designated at their ends by specific target sequences that are not commonly found elsewhere in the genome. A protein, called a recombinase, cuts the DNA at its target sites and rearranges it. Scientists use this technique to exchange a naturally occurring DNA sequence for an altered or deleted gene to gain insight into the gene's normal function or how it contributes to disease.

DOD, VA should take stronger steps to combat tobacco use in military, veteran populations
WASHINGTON -- Because tobacco use impairs military readiness, harms the health of soldiers and veterans, and imposes a substantial financial burden on the departments of Defense and Veterans Affairs, these agencies should implement a comprehensive strategy to achieve the Defense Department's stated goal of a tobacco-free military, says a new report from the Institute of Medicine. DOD should gradually phase in a ban on tobacco use in the military, starting at military academies and officer training programs and among new recruits, the report says. DOD should also stop selling tobacco products in Army and Air Force commissaries -- Navy and Marine Corps commissaries already do not sell them -- and should stop selling them at a discount in military exchanges and other stores. In addition, Congress should allow VA to establish tobacco-free medical centers.

Smokers putting their loved ones at risk of heart attacks
Researchers at University College London and St George's, University of London measured recent exposure to tobacco smoke in non-smoking middle-aged men taking part in the British Regional Heart Study by measuring the levels of cotinine - a compound carried in the blood - at two time points 20 years apart. A blood cotinine level above 0.7ng/mL is associated with a 40% increase in the risk of a heart attack (2), and other studies have suggested that even a level of 0.2ng/mL may increase the risk (3). The researchers found that while in 1978-80, 73% of men had a cotinine level above 0.7ng/mL, by 1998-2000 that proportion had fallen to 17%.

Physicians lack smoking cessation training
Physicians and other health-care providers may advise their patients to quit smoking, but few providers have the adequate training to follow their patients through the cessation process. New research presented at CHEST 2008, the 74th annual international scientific assembly of the American College of Chest Physicians (ACCP), shows that 87 percent of physicians and other medical professionals receive less than 5 hours of training on tobacco dependence and less than 6 percent knew Agency for Healthcare Research and Quality (AHRQ) treatment guidelines for tobacco dependence, including the signs of nicotine withdrawal. Researchers speculate that this lack of knowledge related to tobacco dependence treatment may, in turn, affect quit rates among smokers.

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.
