Warning lights mark shellfish that aren’t safe to eat

Red tides and similar blooms can render some seafood unsafe to eat, though it can be difficult to tell whether a particular batch harbors toxins that cause food poisoning. A new kind of marker developed by chemists at the University of California,...

Multiple sclerosis drug serves as model for potential drugs to treat...

Scientists are reporting that variants of a drug already approved for treating multiple sclerosis show promise as a long sought treatment for victims of bioterrorist attack with botulinum neurotoxin -- which is 10,000 times deadlier than cyanide a...

Key player in detoxification pathway isolated after decades of searching

Chemical reactions are happening all over the place all the time--on the sun, on the Earth and in our bodies. In many cases, enzymes help make these reactions occur. One family of enzymes, called cytochrome P450s (P450), is important because they he...

Iron stimulates blooms of toxin-producing algae in open ocean, study finds

SANTA CRUZ, CA--A team of marine scientists has found that toxin-producing algae once thought to be limited to coastal waters are also common in the open ocean, where the addition of iron from natural or artificial sources can stimulate rapid growth...

Moved by religion: Mexican cavefish develop resistance to toxin

COLLEGE STATION, Nov. 4, 2010 -- A centuries-old religious ceremony of an indigenous people in southern Mexico has led to small evolutionary changes in a local species of fish, according to researchers from Texas A&M University. Since before th...

Treatment for S. aureus skin infection works in mouse model

Scientists from the National Institutes of Health and University of Chicago have found a promising treatment method that in laboratory mice reduces the severity of skin and soft-tissue damage caused by USA300, the leading cause of community-asso...

Researchers find second anthrax toxin receptor

Building on their 2001 discovery of a cellular doorway used by anthrax toxin to enter cells, University of Wisconsin Medical School researchers have found a second anthrax toxin doorway, or receptor. The finding could offer new clues to preventing the toxin's entrance into cells. The researchers also have found that when they isolated a specific segment of the receptor in the laboratory, they could use it as a decoy to lure anthrax toxin away from the real cell receptors, preventing much of the toxin from entering cells and inflicting its usually fatal damage.

Cerebral palsy symptoms improve with botulinum toxin

Children with cerebral palsy show long-term improvement through treatment with botulinum toxin, according to new research. Children treated with the drug had improvements ranging from making voluntary movements for the first time to improved stance and walking, according to the study's lead author, neurologist Marc P. DiFazio, MD, of Walter Reed Army Medical Center in Washington, DC.
