Analysis of different sweeteners and sweet substances

The most important factor in what kind of sweetener people prefer has little to do with how sweet it tastes. Rather, it has more to do with other tastes in the sweetener, such as bitterness or sourness, new research suggests.

Soy intake may be associated with a small reduction in the risk of breast cancer

However, because of limitations and inconsistencies in the studies examined within the meta-analysis, the authors caution that evidence is not sufficient to recommend soy as a means of preventing breast cancer.

IL-25 both promotes and limits inflammatory diseases

The same signal responsible for promoting the type of immune responses that cause asthma and allergy can also limit the type of inflammation associated with debilitating diseases like inflammatory bowel disease, arthritis and multiple sclerosis, according to researchers from the University of Pennsylvania School of Veterinary Medicine.

Research provides clues to obesity's cause

Hot fudge sundaes and french fries aside, new research suggests obesity is due at least in part to an attraction between leptin, the hormone that signals the brain when to stop eating, and a protein more recently associated with heart disease.

Physicians with more experience are better able to detect a third heart sound that is an indicator of heart disease

Physicians with more experience are better able to detect a third heart sound that is an indicator of heart disease, according to a study on stethoscope accuracy in cardiac patients at UCSF Medical Center.

Rubber research set to curb life-threatening allergies

Research being undertaken at The University of Queensland (UQ) could prevent potentially life-threatening allergic reactions to conventional latex rubber which occur in 10 per cent of the population.

Drug firms in the business of 'diseasemongering'

Australian scientists have accused drug companies of inventing diseases to sell more of their products.

That mistake will cost you and your brain knows staight away!

According to a team of researchers in the U.S.a particular part of the brain called the rostral anterior cingulate cortex, or rACC, becomes much more active when a person realizes he or she has made an error that carries consequences - for instance, losing money.

Statins may be able to play a role in preventing or slowing heart valve disease

Research to be published in the April 18 issue of the Journal of the American College of Cardiology provides the first explanation of an active rather than passive process that leads to heart valve degeneration, furthering a Northwestern researcher's effort to lead a paradigm shift in the medical community's beliefs about the cause of valve disease.

New insights into how anti-rejection drug daclizumab (Zenapax) helps MS patients

A research team led by the University of Cincinnati's Bibiana Bielekova, MD, report new insights into the role of the MS drug daclizumab (Zenapax) in the Proceedings of the National Academy of Sciences.

Benefit of chemotherapy in breast cancer depends on estrogen status of tumors

When it comes to chemotherapy treatment for women whose breast cancer has spread to their lymph nodes, the estrogen status of their tumors matters, says a team of researchers in the Journal of the American Medical Association.

Researchers identify the role of a protein in hemoglobin gene silencing

Virginia Commonwealth University Massey Cancer Center researchers have identified the role of a protein in hemoglobin gene silencing that may one day be a potential target for the treatment of genetic blood disorders like sickle-cell anemia and beta-thalassemia on the molecular level.

New model of p53 regulation has important implications for the development of anticancer drugs

Genetically engineered mice convinced scientists at the Salk Institute for Biological Studies that it was time to overhaul widely held beliefs about how a powerful tumor suppressor called p53 is controlled in cells. Their new model of p53 regulation has important implications for the development of anticancer drugs.

Single dose of stem cells produce robust behavioral recovery in animal models for stroke, cerebral palsy

A single dose of adult donor stem cells given to animals that have neurological damage similar to that experienced by adults with a stroke or newborns with cerebral palsy can significantly enhance recovery from these types of injuries, researchers say.

Research explains why recipients of growth hormone therapy may develop colon polyps

The use of growth hormone therapy has been linked in some people to the development of colon polyps, a possible precursor to colorectal cancer - but medical researchers have debated the extent of a cancer risk.

DNA "dark state" findings help explain evolution of life

Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry.

St. John's wort and Echinacea increase activity of enzyme in the liver and intestine

St. John's wort and Echinacea, two widely-used herbal preparations, have been found to increase activity of a specific enzyme in the liver and intestine, an enzyme involved in the metabolization of roughly one in every four pharmaceutical drugs on the market today, reports a clinical pharmacologist at Indiana University School of Medicine.

Targeted mutations in mice uncover two key molecular events linked to learning

Johns Hopkins researchers have used mouse mutants to define critical steps involved in learning basic motor skills. The study focuses on the behavior of two proteins and the specific steps they take to control a neuron's ability to learn by adapting to signals from other nerve cells.

Scientists identify a new gene that causes the spread of cancer

Professor Philip Rudland, Dr Guozheng Wang and Dr Roger Barraclough from Liverpool University's Cancer and Polio Research Fund Laboratories have discovered an additional member of the S100 family of protein genes - S100P - that causes the spread of cancerous cells from an original tumour to other parts of the body.

Lubricin research points to future therapies for osteoarthritis

New evidence to explain how the body's natural joint lubricant prevents the wear and tear that can lead to osteoarthritis has been uncovered by researchers at Duke University's Pratt School of Engineering.The findings may lead to new methods for treating arthritis, the researchers said.
