Exposure to toxin domoic acid might negatively affect unborn children

Duke University Medical Center researchers have found that the naturally occurring marine toxin domoic acid can cause subtle but lasting cognitive damage in rats exposed to the chemical before birth. Humans can become poisoned by the potentially lethal, algal toxin after eating contaminated shellfish.

New ways to enhance or block fertilization

Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.

Single molecular anchor holds the key to treating many types of bacterial meningitis

By blocking the molecule's anchoring ability, researchers may be able to find a way to stave off the most common serious infection of the central nervous system and a major cause of childhood death and disability. The researchers' findings appear in the September 2005 issue of the Journal of Clinical Investigation.

Rotenone study may lead to novel therapies for Parkinson's disease

Neuroscientists from the University at Buffalo have described for the first time how rotenone, an environmental toxin linked specifically to Parkinson's disease, selectively destroys the neurons that produce dopamine, the neurotransmitter critical to body movement and muscle control.

Protein that protects the body from tissue damage also increases the risk of tumors

You win some, you lose some. A protein that protects the body from tissue damage also increases the risk of tumors, according to a study conducted at Washington University School of Medicine in St. Louis. Moderate reduction of the protein level protects against tumor formation but increases susceptibility to tissue injury.

Pig brain cell transplant looks hopeful for treating Huntington's disease

According to researchers at Australian bioscience company Living Cell Technologies (LCT), if approved, pig brain cells wrapped in a seaweed derivative could be implanted into human brains by sometime next year to treat Huntington's disease.

Pseudomonas aeruginosa has broken the immune system's code

The human opportunistic pathogen, Pseudomonas aeruginosa, has broken the immune system's code, report researchers from the University of Chicago, enabling the bacteria to recognize when its host is most vulnerable and to launch an attack before the weakened host can muster its defenses.

Two studies reveal how plague disables immune system

Two studies by researchers at the University of Chicago show how the bacteria that cause the plague manage to outsmart the immune system and how, by slightly altering one of the microbe's tools, the researchers produced what may be the first safe and effective vaccine.

Cause of chronic sinus infections lies in the nasal mucus

Mayo Clinic researchers have found that the cause of chronic sinus infections lies in the nasal mucus -- the snot -- not in the nasal and sinus tissue targeted by standard treatment. The findings will be published in the August issue of Journal of Allergy and Clinical Immunology and are available online.

Plant toxins in the diets of early humans drove the evolution of taste

Plant toxins in the diets of early humans drove the evolution of a bitter taste receptor better able to detect them, suggests new genetic research by scientists at University College London, Duke University Medical Center, and the German Institute of Human Nutrition.

Results demonstrate the safety and tolerability of ABthrax treatment for Anthrax infection

Human Genome Sciences has announced that results published in the current issue of Clinical Infectious Diseases demonstrate that the first investigational agent against anthrax infection to be evaluated in a clinical study since the 2001 anthrax attacks in the United States, is safe, well tolerated and achieves the blood levels predicted by relevant animal models as necessary to afford significant protection from the lethal effects of the anthrax toxin

Smokers believe light or herbal cigarettes are less harmful

Nearly one-fourth of cigarette smokers believe that so-called reduced-exposure tobacco products - such as "light," herbal or reduced nicotine cigarettes - are less harmful to their health than conventional cigarettes, a new study finds. However, such beliefs are not backed up by existing evidence, according to the study's authors.

Showering in manganese-contaminated water could have permanent effects on the nervous system

A new analysis based on animal studies suggests that showering in manganese-contaminated water for a decade or more could have permanent effects on the nervous system. The damage may occur even at levels of manganese considered safe by the Environmental Protection Agency, according to researchers from Wake Forest University School of Medicine.
