Breath-analysis testing may prove to be an effective method for detecting the damaging lung-bacteria growth seen in cystic fibrosis

By using a chemical analysis method developed for air-pollution testing, UCI chemists and pediatricians have found that people with cystic fibrosis exhale higher concentrations of sulfur compounds from their lungs than do people who don't have the disease.

New approaches to counteract platelet shortages

Availability of safe platelets is a fundamental blood transfusion challenge and can be especially problematic in times of emergency. Several studies presented at the annual American Association of Blood Banks (AABB) meeting today demonstrate new approaches to counteract platelet shortages by enhancing the safety of whole blood derived platelets, precluding the need to rely on only those obtained through apheresis.

Significant step forward in the genome era

In what promises to be a significant step forward in the genome era, the National Human Genome Research Institute (NHGRI) today announced plans to devote a portion of its large-scale sequencing capacity to efforts aimed at identifying the genetic roots of specific diseases that have long eluded gene hunters.

Fijiian seaweed shows potential to kill cancer cells, bacteria and the HIV virus

Researchers have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed that lives in the shallow coral reef along the coastline of Fiji in the south Pacific Ocean.

Quest to develop synthetic versions of rare natural substances to cure tobacco-related diseases

Within a laboratory on the Florida State University campus, a chemist leads a team of researchers in a quest to develop synthetic versions of rare natural substances. If all goes well, the team’s efforts could pay off in the form of the next generation of cancer-fighting drugs.

New Orleans floodwaters not as toxic as previously thought

The floodwaters that inundated New Orleans immediately following Hurricane Katrina were similar in content to the city’s normal storm water and were not as toxic as previously thought, according to a study by researchers at Louisiana State University.

New discoveries help explore the function of regulatory T cells in autoimmune disease and in cancer

More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years.

Aging may intensify and prolong feeling run down when common infections like the flu occur

A new study, done with mice and published in the Federation of the American Societies of Experimental Biology Journal, suggests that miscommunication between the immune system and brain may be to blame for extended sickness symptoms and other cognitive disorders in elderly people and animals with an infection.

Vanadium may help prepare the body to recover speedily from infections

Dietary supplements containing vanadium are used by body builders to help beef up muscles and by some diabetic people to control blood sugar. New research now suggests the naturally occurring but easily toxic element may help prepare the body to recover speedily from infections from gram-negative organisms such as E. coli.

Nabi Biopharmaceuticals granted Staphylococcus Antigen and Vaccine patent

Nabi Biopharmaceuticals has announced that it has been granted U.S. Patent No. 6,936,258 entitled "Staphylococcus Antigen and Vaccine" by the U.S. Patent and Trademark Office for the composition of a strategically important glycoprotein-based antigen (GP-1) associated with three Staphylococcal strains: S. epidermidis, S. haemolyticus and S. hominis.

High fat foods can soothe inflammation

"Take two cheeseburgers and call me in the morning," may sound like far-fetched medical advice. After all, high fat foods can worsen blockages in blood vessels.

Real dangers from environmental toxins most likely occur early in life

Exposure of developing fetuses and newborns to low levels of environmental toxins such as lead, mercury and dioxin, as well as nicotine and ethanol, could be behind the recent sharp rises in asthma, allergies and autoimmune disorders like lupus, says a Cornell University researcher.

Tonsils reveal information that helps understand lupus

By snipping out and analyzing tiny samples of patients' tonsils, scientists have identified a key cellular checkpoint that is somehow bypassed in lupus patients, where harmful immune cells that normally are squelched by the body are mistakenly granted access.

Researchers find gene that is important for the control of fundamental rhythms in nematode worms

University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping.

Researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model

The first close-up look at a pro-inflammatory signaling molecule involved in immune response in mammals suggests that researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model, scientists say.

Discovery of molecular roots of asthma, arthritis, and multiple sclerosis

The molecular roots of inflammatory and autoimmune diseases such as asthma, arthritis, and multiple sclerosis (MS) have been discovered by a team of researchers led by The University of Texas M. D. Anderson Cancer Center. They say their findings may point to ways to effectively treat these diseases - if not stop them before they start.
