Scientists take a close look at early events in immune response

A Sandia National Laboratories research team led by Anup Singh is taking a new approach to studying how immune cells respond to pathogens in the first few minutes and hours of exposure.

Australian Tissue Bank may help find breakthrough in the fight against cancer

The cure for cancer is one step closer this week with the first collections of cancer tissue taking place at the new Wesley Research Institute Tissue Bank.

Filtering white cells from donor blood before transfusion is much safer for patients

The practice of removing the white cells from blood is called leukoreduction. But despite the recommendations of two national advisory committees in 10 years that voted in favor of all patients in the United States receiving leukoreduced blood, ("universal leukoreduction"), the practice is still not wholly supported in the medical community, nor recommended by the Food and Drug Administration. Part of the reason is fear of increased cost.

Fungal compound galiellalactone may combat prostate cancer

Can a substance from a fungus that grows on decaying trees provide a cure for aggressive prostate cancer? This is the hope of researchers at Lund University in Sweden.

Compounds derived from blue agave may be more effective way to deliver drugs to the colon

Compounds derived from the blue agave, a fruit used to make tequila, shows promise in early laboratory studies as a natural, more effective way to deliver drugs to the colon than conventional drug-carriers, according to chemists at the University of Guadalajara in Mexico.

Advances in clinical cardiology

Three studies being presented at the American College of Cardiology's Innovation in Intervention: i2 Summit 2007 in New Orleans, La., highlight the breadth of research propelling advances in clinical cardiology.

Unusual protein helps cell bypass damage when making new DNA

Scientists have discovered how an unusual protein helps a cell bypass damage when making new DNA, thereby averting the cell's self-destruction.

New contrast agent selectively targets and highlights malignant micro-calcifications in the breast

Harvard Medical School researchers are working on a new, simpler way to distinguish malignant tumors from non-cancerous masses when screening for breast cancer.

Chromosomal microarray analysis accurately detects abnormalities in individual chromosomes

Two years and more than 2,000 samples after researchers at Baylor College of Medicine started to use a new gene-chip technology called chromosomal microarray analysis to look for potential genetic abnormalities in children, they find that it is remarkably sensitive in detecting abnormalities in individual chromosomes, according to a report that appears online today in the journal Public Library of Science ONE.

Synthetic molecule helps detect heart attack in the making

A new bright spot in heart disease research may soon allow physicians to peer directly into patients' blood vessels and find dangerous cholesterol-filled plaques before they rupture and cause a heart attack.

Optical biopsy finds cancers in first tests on human tissue

In its first laboratory tests on human tissue, a light-based probe built by researchers at Duke University's Pratt School of Engineering almost instantly detected the earliest signs of cancer in cells that line internal organs.

Drug-eluting stents are disappointing in bypass grafts - sometimes!

While drug-eluting stents are effective in keeping open bypassed heart veins that aren?t too diffuse (filled with cholesterol plaque), a new study by cardiologists at Jefferson Medical College shows that they fare less well in keeping open bypassed veins with longer blockages.

Immunity to cancer stem cells may help protect people with a precancerous condition from developing the full-blown disease

Although stem cells hold incredible promise in the fight against certain diseases, in cancer they're anything but helpful. In fact, mounting evidence is showing that a tumor's growth and spread may depend on "cancer stem cells," which comprise only a very small subset of the tumor.

Six centers of excellence for influenza research and surveillance established in U.S.

The National Institute of Allergy and Infectious Diseases (NIAID) has announced it is awarding $23 million per year for seven years to establish six Centers of Excellence for Influenza Research and Surveillance.

Gender differences and skin cancer

Inherent gender differences – instead of more sun exposure – may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say researchers at Ohio State University Medical Center.

USAID strengthens fight against avian influenza globally

The U.S. Government through the U.S. Agency for International Development (USAID) announced a one- year, $19 million project to provide critical commodities to fight avian influenza.

Precise region in the frontal cortex may be specialised for learning social information

Is there a specific memory for events involving people Researchers in the Vulnerability, Adaptation and Psychopathology Laboratory (CNRS/University Paris VI France ) and a Canadian team at Douglas Hospital, McGill University (Montreal), have identified the internal part of the prefrontal cortex as being the key structure for memorising social information.

Revving up a crucial set of muscle genes improves muscular dystrophy symptoms in mice

Scientists at Dana-Farber Cancer Institute have shown in a laboratory study that revving up a crucial set of muscle genes counteracts the damage caused by a form of muscular dystrophy.

Total sleep time affects morning testosterone levels

The testosterone levels of healthy men decline as they get older. As sleep quality and quantity typically decrease with age, objectively measured differences in the amount of sleep a healthy older man gets can affect his level of testosterone in the morning, according to a study published in the April 1st issue of the journal SLEEP.
