One-of-a-kind imaging probe reveals secrets useful for drug discovery

...amine the venom, which the walking stick sprays to defend itself from predators. Similar to the magnetic resonance imagers used to examine patients in hospitals, this analytical tool uses much stronger magnetic fields to study smaller samples, allowing scientists to study molecules atom by atom. But what...

Stanford scientists make major breakthrough in regenerative medicine

...biomedical science is to understand life so we can defend our bodies against injury, deformity, and disease. The ultimate medical treatment would be to change an abnormal organ or tissue back to its vibrant, normal state," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "This study is a l...

Buckyballs used as 'passkey' into cancer cells

...ic and Biomolecular Chemistry. All living cells defend themselves by walling off the outside world. Cell walls, or membranes, form a protective cocoon around the cell's inner machinery and its DNA blueprints. "Drugs are far more effective if they're delivered through the membrane, directly into the ce...

Xylitol reduces risk of cavities

...ernilla Lif Holgerson in the dissertation she will defend at Umeå University in Sweden on February 23. Xylitol is a sugar alcohol that is produced by reduction of the sugar xylose, or wood sugar. Xylitol occurs naturally in fruits and berries, such as pears and strawberries. It is used in sugarless sweet...

Scientists find genes involved in the battle between Hessian flies and wheat

...to feed on resistant wheat plants that are able to defend themselves, Shukle said. While the insects can't establish feeding sites on resistant plants, the larvae can alter the physiology and change the level of certain proteins in susceptible plants. This forces the plant to feed the larvae. On resista...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...k of an enzyme that insects' immune systems use to defend themselves from attack. Although such so-called gene-for-gene interactions are thought to be common in diseases, very few examples of a single gene in a pathogen targeting a single gene in an animal or human host have been identified so far. Ph...

Mule deer moms rescue other fawns

...s whether a fawn is her own before she steps in to defend it. As a result, whitetail fawns suffer considerably more predation during the first months of life than do mule deer fawns." Mule deer may have developed a more effective aggressive defence because they rely on fighting to protect themselves agai...

HIV and malaria combine to adversely affect pregnant women and their infants

... Until now the mechanisms by which pregnant women defend themselves against malaria and how HIV impairs this defence have been unknown, but a paper published in PLoS Medicine (Public Library of Science) pinpoints how the virus targets the immune response in pregnant women. "PAM can be a deadly condition th...

Newly discovered antibody may be body's natural defense against Alzheimer's

...curring antibodies in human blood that may help to defend against this form of dementia as well as other neurodegenerative diseases. The newly found antibodies selectively target aggregates of beta amyloid proteins called "oligomers" that are toxic to brain cells, while ignoring the benign single-molecule...
