Nanomaterials key to new strategies for blocking metastasis

A new treatment strategy using targeted nanoparticles to block metastasis with anti-cancer drugs leads to good results using significantly lower doses of toxic chemotherapy, with less collateral damage to surrounding tissue, according to a collaborative team of researchers at the Center of Nanotechnology for Treatment, Understanding, and Monitoring of Cancer at the University of California, San Diego. In designing this system, the investigators, led by David Cheresh, Ph.D., have identified what may become a generic method for using nanotechnology to target metastasis.

Improving quantum dot synthesis

Materials researchers at the National Institute of Standards and Technology (NIST) have developed a simplified, low-cost process for producing high-quality, water-soluble quantum dots for biomedical applications.

Natural substance Argyrin shows promise for new cancer therapies

The effective treatment of many forms of cancer continues to pose a major problem for medicine. Many tumours fail to respond to standard forms of chemotherapy or become resistant to the medication.

A paradigm shift for targeted cancer therapy

We already know that recycling benefits our planet; and now new research suggests that the cellular version might be useful for battling cancer.

Novel ways to boost vaccination or natural defenses

Our bodies rely on the production of potent, or 'high affinity', antibodies to fight infection. The process is very complex, yet Sydney scientists have discovered that it hinges on a single molecule, a growth factor, without which it cannot function.

Discovery of new function for an old enzyme in sialidosis

The lack of a single protein usually thought of as a run-of-the-mill enzyme that helps to recycle molecules in cells causes an incurable and often fatal disease of children, according to St. Jude Children's Research Hospital investigators.

Discovery of molecule that kills kidney cancer cells

Kidney cancer patients generally have one option for beating their disease: surgery to remove the organ. But that could change, thanks to a new molecule found by Stanford University School of Medicine researchers that kills kidney cancer cells. Ideally, the researchers said, a drug created from this molecule would help fight the life-threatening disease while leaving patients' kidneys intact.

Radioactive "tag" added to formaldehyde helps monitor body chemistry, disease

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a simple, fast method for adding a radioactive "tag" to formaldehyde, a common organic chemical.

Researchers solve structure of proteins known as sodium glucose co-transporters

Researchers at the David Geffen School of Medicine at UCLA have solved the structure of a class of proteins known as sodium glucose co-transporters (SGLTs), which pump glucose into cells.

Gene technique that alters CCR5-producing gene increases resistance to HIV in mice

Altering the gene that produces CCR5 protein on the surface of immune cells using a harmless virus was found to significantly increase resistance to HIV in mice, according to a study published Sunday in the journal Nature Biotechnology, the Press Trust of India reports (Press Trust of India, 7/1).

New target for the potential treatment of tuberculosis

Scientists have uncovered a new target for the potential treatment of tuberculosis (TB), finally resolving a long-running debate about how the bacterial cell wall is built.

Research sheds light on the molecular basis of SIDS

Sudden Infant Death Syndrome (SIDS) is a condition that unexpectedly and unexplainably takes the lives of seemingly healthy babies aged between a month and a year.

Statins have unexpected effect on pool of powerful brain cells

Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells important to brain health as we age, scientists at the University of Rochester Medical Center have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.

Chemists create synthetic catalyst that folds its molecular structure into a specific shape

When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly specialized catalysts, and finding one in just the right shape to connect with certain molecules can be difficult. Natural catalysts, such as enzymes in the human body that help us digest food, get around this problem by shape-shifting to suit the task at hand.

Hydrogen sulfide significantly improves survival after extreme blood loss

For the first time, researchers have demonstrated that the administration of minute amounts of inhaled or intravenous hydrogen sulfide, or H2S - the molecule that gives rotten eggs their sulfurous stench - significantly improves survival from extreme blood loss in rats.
