Repeated methamphetamine use causes long-term adaptations in brains of mice, researchers find
Repeatedly stimulating the mouse brain with methamphetamine depresses important areas of the brain, and those changes can only be undone by re-introducing the drug, according to research at the University of Washington and other institutions. The study, which appears in the April 10 issue of the journal Neuron, provides one of the most in-depth views of the mechanisms of methamphetamine addiction, and suggests that withdrawal from the drug may not undo the changes the stimulant can cause in the brain.

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.

Survey finds elevated rates of new asthma among WTC rescue and recovery workers
Findings released today by the Health Department shed new light on the health effects of exposure to dust and debris among workers who responded to the World Trade Center disaster on September 11, 2001. The data, drawn from the World Trade Center Health Registry, show that 3.6% of the 25,000 rescue and recovery workers enrolled in the Registry report developing asthma after working at the site. That rate is 12 times what would be normally expected for the adult population during such a time period. The paper was published today in the journal Environmental Health Perspectives and is available online at www.ehponline.org.

No drugs exist to protect the public from the high levels of radiation that could be released by a dirty bomb or nuclear explosion.

But now researchers at Washington University School of Medicine in St. Louis report they have developed an agent that protects cells from the lethal effects of radiation, regardless of whether it is given before or after exposure.
