Mushrooms help lower cholesterol and keep hearts healthy

An analysis of previously uncharted chemical contents, mostly carbohydrates, in U.S.-consumed mushrooms shows that these fruity edible bodies of fungi could be tailored into dietary plans to help fill various nutritional needs.

Abandoned bones suggest TB wiped out leprosy in battle of killer diseases

The spread of tuberculosis may have killed off leprosy in Europe in the Middle Ages, according to research published in the latest issue of the Royal Society Proceedings B.

Research confirms how early-life events shape later physiology

Underscoring the value of good prenatal care, new research suggests that early infection may create a cognitive vulnerability that appears later during stress on the immune system.

Link between heart disease and periodontal bacteria

Researchers report this week that older adults who have higher proportions of four periodontal-disease-causing bacteria inhabiting their mouths also tend to have thicker carotid arteries, a strong predictor of stroke and heart attack.

People with gum disease are more likely to suffer from atherosclerosis

A new study by researchers at Columbia University Medical Center provides the most direct evidence to date that preventing gum disease could significantly improve your chances of avoiding vascular problems.

Bacterial spread all down to chance: some strains 'just the luckyones'

Scientists have discovered that factors such as human immunity and drug resistance are less important to the success of bacterial spread than previously thought.

Basis for deciding cost effectiveness of TB vaccination programmes questioned

Current risk assessment methods, which are used to inform the timing and extent of tuberculosis (TB) vaccination programmes, may overestimate the real risk of contracting the disease up to threefold, reveals research in Thorax.

Aircraft drinking water contaminated with bacteria

A second round of Environmental Protection Agency (EPA) testing shows that 17.2 percent of 169 randomly selected passenger aircraft carried water contaminated with total coliform bacteria.

Newly discovered virus, New Haven coronavirus

A newly discovered virus may be responsible for many respiratory tract illnesses in infants and children, and may be associated with an important multi-organ disease whose cause has remained a mystery for decades, according to articles in the Feb. 15 issue of The Journal of Infectious Diseases, now available online.

Anti-seizure drugs slow aging in roundworms

Researchers at Washington University School of Medicine in St. Louis have discovered that a class of anti-seizure medications slows the rate of aging in roundworms. The worms, when exposed to drugs used to treat epilepsy in humans, lived longer and retained youthful functions longer than normal.

Scientists examine the role of small sputum macrophages in the widespread disease chronic obstructive bronchitis

COPD (chronic obstructive pulmonary disease) is one of the most common fatal diseases worldwide. In Germany alone, there are about 3-5 million patients affected. COPD includes both chronic obstructive bronchitis and emphysema. Both represent irreversible changes of the central and lower respiratory tract which are accompanied by coughing, mucus production and difficulty in breathing.

Novel treatment promises to be an effective cure for tuberculosis

Researchers in Belgium have uncovered a novel treatment that promises to be an effective cure for tuberculosis (TB). The respiratory disease has been experiencing a major global comeback due to the emergence of resistant strains of the bacteria that causes it and the spread of AIDS.

Now significantly easier to search long stretches of DNA for genetic changes associated with disease

The researchers developed a method called direct genomic selection that accelerates the transition between family or population-based studies of disease inheritance patterns and identification of genetic variations that may contribute to disease.

Protein discovery with medical implications

It was a transforming moment. Researchers could barely believe their eyes. A molecular blob of a protein reshaped itself into a molecular Pacman in order to free new viruses from the inside of a bacterial cell.

Mutated gene may provide better idea of how cancer develops and progresses

Scientists are taking the first steps to find out how a gene that is mutated in many cancer cells functions in healthy cells.

Gene sequencing explains why natural bioremediation 'bug' has big appetite for chlorinated pollutants

"The born-to-dechlorinate bug" is what Cornell University researchers called Dehalococcoides ethenogenes Strain 195 when they found the bacterium obligingly detoxifying the pollutant PCE, or perchloroethylene (a chlorinated solvent used for dry cleaning), in sludge from an Ithaca, N.Y., sewage treatment plant.

Antibiotics protect nerves in mice by turning on genes

A family of antibiotics that includes penicillin may help prevent nerve damage and death in a wide variety of neurological diseases, including Lou Gehrig's disease, dementia, stroke, and epilepsy, Johns Hopkins researchers have found.

6 Jan 2005

New protein discovered holds promise for use in medicine and nanoscience

Researchers at the Hebrew University of Jerusalem have succeeded in discovering and isolating a new protein from the poplar tree with special structural and qualitative characteristics that could have consequences for development of future nanocapsules for drug delivery to cancer cells.

5 Jan 2005

Technology that could double the effectiveness of cancer drugs

To identify the best treatment for recurrent ovarian cancer, researchers at Yale School of Medicine are studying a technology called the Yale apoptosis assay in combination with another technology called the ChemoFX assay, which could double the response rate to existing drugs.

Genomics tools provide clues to what causes 400 million cases of gastrointestinal disease each year

In a study that could benefit medical and food-safety research, scientists have used comparative genomics tools to find clues about why some strains of the bacterium Campylobacter – which each year cause more than 400 million cases of gastrointestinal disease – are more virulent than others.
