Stroke treatment a step closer after trial

...amage to the cells by as much as half; if we could cut cell damage in patients by even a third it would be a very significant step forward in treating stroke." IL-1ra (interleukin-1 receptor antagonist) is the naturally occurring antagonist of the protein interleukin-1 (IL-1), which the same scientists ...

Envisat radar surveillance protects endangered prehistoric fish

...system based on Envisat and Radarsat-1 imagery has cut the number of illegal fishing incursions in the vicinity of Kerguelen Island by nine-tenths. Run for the benefit of the French maritime authorities by the firm CLS (Collecte, Localisation Satellites), a subsidiary of the French space agency CNES, the...

Scientists use stem cells to grow cartilage

...ving head and neck cancers, surgeons often have to cut away parts of cartilage, and then take grafts from other parts of the body. With this new technique doctors would potentially be able to take stem cells from the patient, grow them in a laboratory, and then transplant them after the surgery. This wo...

New understanding of regeneration gained by Forsyth scientists

...deal for studying this process. When the worms are cut in half, the bottom section of the worm grows a head and the upper section a tail. Scientists have suspected that the ability of previously adjacent cells (on either side of the cut) to adopt radically different fates, as is the case with planaria w...

Some good news for the world's poor

...nal Rice Research Institute has also been severely cut in recent years. IRRI's budget of $32.6 million in 2000 was the lowest in 20 years, and was only 63 percent of its peak of $51.6 million (measured in 2000 prices) in 1990." IRRI Director General Dr. Zeigler said that, unfortunately, this trend has c...

Antibacterial coatings cut infection rates

...nts and biomedical devices such as catheters could cut infection rates following surgery and significantly reduce health care costs and improve quality of life for patients, researchers at the University of South Australia have found. A significant number of hip and knee implants are prone to infection ...

Portable cocaine sensor developed at UC Santa Barbara

...sensor can detect cocaine no matter what they have cut it with: powdered sugar, flour, or the coffee that is sometimes used to mask the smell from dogs." At this point the new sensor detects cocaine in the blood or saliva to a degree of a few micromolars. This is equivalent to the concentration of cocai...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

A cut can be life-threatening for people with hemophilia, whose bodies don't produce enough of a protein that prevents prolonged bleeding. Now University of Florida researchers may be one step closer to finding a safe way to spur production of this missin...
