Investigating the measles virus as a tool to kill multiple myeloma

...rotein. NIS is produced by the thyroid where it attracts and concentrates iodine. This characteristic of the NIS protein can be exploited as a target in cancer therapy because it can concentrate radioactive iodine, thus providing a way to selectively irradiate cancer cells, image the tumors and monitor reg...

Brain works more chaotically than previously thought

...cate that this is not the case." The messenger attracts insulating cells Together with his colleagues Dr. Maria Kukley and Dr. Estibaliz Capetillo-Zarate, Dietrich has conducted a careful examination of the "white matter" in the brain of rats. This substance contains the "cable ducts" linking the righ...

Microbes compete with animals for food by making it stink

... consume them instead. To test whether aged meat attracts fewer consumers than fresher meat, researchers baited crab traps with menhaden -- a fish typically used for bait -- that had been rotting in a pool of warm water ?some of it for one day and the rest for two days. They also baited other traps with fre...

Female guppies risk their lives to avoid too much male attention

...re predators lurk. The males' bright coloring also attracts predators, making it too dangerous for them to follow. "Understanding why and how [sexual segregation] occurs is essential if we are going to conserve and protect species and habitats," explains Croft, who points out that fish are not the only spec...

Rice scientists unveil 'nanoegg'

...ve and the other negative ?much like a magnet that attracts on one end and repels on the other. "Without a dipole moment, there is no 'handle' for light to grab hold of," Nordlander said. "In symmetric nanoshells, most of the light energy is lost to these 'dark modes.' With symmetry breaking, we are able to...

Proteins spur diabetic mice models to grow blood vessels, nerves

...nding author. "We now have a (growth) factor that attracts both blood vessels and nerves--that's why it's unique for diabetes," Li said. "This demonstrates that netrins are critical for development and may be important as a new therapy." Li and fellow researchers from the University of Utah and Stanford alr...

Jefferson scientists identify gene defect leading to abnormal skin development and cancer

...ng Li, an earlier doctoral student of Sorensen -- attracts the females to males. After spawning, which takes a few weeks, the adults die. It has taken Sorensen and his colleagues about 15 years to find, isolate and purify the pheromone so that Hoye and his colleagues could identify and synthesize it. The k...

Gradient guides nerve growth down spinal cord

The same family of chemical signals that attracts developing sensory nerves up the spinal cord toward the brain serves to repel motor nerves, sending them in the opposite direction, down the cord and away from the brain, report researchers at the University of Chicago in the September 2005 issue of ...

Unusual antibiotics show promise against deadly 'superbugs'

...ehaves in the body. For example, collagen normally attracts cells to close up a wound and form scar tissue. But this property is not always desirable; a clot can be dangerous inside a blood vessel or at certain injury sites, where scar tissue can interfere with the formation of new nerve connections. Modifie...

Antibiotic might fight HIV-induced neurological problems

...ted from brain cells under attack from HIV or SIV, attracts infection-fighting cells known as macrophages, which then enter the brain. The influx of these cells contributes to swelling and inflammation known as encephalitis. The other protein, p38, helps trigger a series of events that result in a cell's prog...
