Tamoxifen-like drug suggests new ways to selectively block estrogen

The ability of an experimental drug known as GW5638 to change the shape of the estrogen receptor is helping researchers understand why drugs like tamoxifen and raloxifene behave the way they do, simulating the effects of estrogen in some tissues and blocking it in others. The finding indicates that this little-known drug may play an important role in preventing, as well as treating, breast cancer...

Motorola researchers develop selective sensors based on carbon nanotubes

A team of researchers from Arizona State University and Motorola Labs, the applied research arm of Motorola Inc., has developed sensors based on carbon nanotubes, microscopically small structures that posses excellent electronic properties. In early tests, the new devices detected the presence of heavy metal ions in water down to parts per trillion levels. Specifically, the researchers de...

Selectively blocking inflammatory signals may protect mice from MS

A new way to preserve the cells that surround and protect nerves could lead to new treatments for demyelinating diseases such a multiple sclerosis, a research team reports in the May 10, 2006, issue of the Journal of Neuroscience. The approach grew out of a novel explanation, quickly gaining followers, for the mechanism of nerve damage caused by multiple sclerosis. Instead of concentratin...

Cells selectively absorb short nanotubes

DNA-wrapped single-walled carbon nanotubes (SWCNTs) shorter than about 200 nanometers readily enter into human lung cells and so may pose an increased risk to health, according to scientists at the National Institute of Standards and Technology (NIST). The results of their laboratory studies appear in an upcoming issue of Advanced Materials.* Eyed for uses ranging from electronic display...

Erectile dysfunction in diabetes is due to selective defect in the brain

A new study sheds additional light on how erectile dysfunction (ED) interacts with diabetes. The study is another step in uncovering the link between the two disorders, and may lead to improved efficacy in treatments. The study, "Lack of Central Nitric Oxide Triggers Erectile Dysfunction in Diabetes," was conducted by Hong Zheng, William G. Mayhan, and Kaushik P. Patel, Departments of Cel...

Selective eating just an evolutionary trait?

Babies will put almost anything in their mouths. But as children get older, they become more selective about what they eat,// particularly if they have not tried it before. Green vegetables and meat can be particularly troublesome.But scientists say thousands of years ago toxins in plants could have harmed children, and meat carried a high risk of food poisoning.So it makes sense that...

New Study Questions Cannibalism As A Worldwide Selective Force

A team of scientists reports that 'mad cow'-like diseases have not been a major force in human history, nor have been cannibalistic rituals that are known to be associated with disease transmission.// In a new study published by the journal Genome Research, Prof. Jaume Bertranpetit at the Universitat Pompeu Fabra and his colleagues used a fresh set of genetic data to show that balancin...

Govt to Pass Amendment to Curb Sex Selective Abortions: Ramadoss

Health and Family Welfare Minister Anbumani Ramadoss Wednesday assured representatives of the civil society and NGOs that the government is willing //to bring amendments in the legislation concerned to prevent sex selective abortions. "The government is willing to bring further amendments in the Preconception and Prenatal Diagnostic Techniques (Prohibition of Sex Selection) Act for st...

Selective Marker Found to Indicate Aggressive Form of Breast Cancer

Researchers have linked a structural protein called nestin to a particularly deadly form of breast cancer, identifying a new biomarker that could lead to earlier detection and better treatment.// In the January 15 issue of Cancer Research, researchers from Dartmouth Medical School demonstrate that nestin could represent a selective biological marker for basal epithelial breast tumors,...
