Sea coral's trick helps scientists tag proteins

...o many scientists, said Sergey Lukyanov, whose lab reports on the Dendra tag in the April 2006 issue of Nature Biotechnology, published in advance online on March 19, 2006. Importantly, Dendra is small enough to highlight proteins without interfering with their folding or function. And the researchers have ...

Wisconsin scientists find a way to make human collagen in the lab

...edings of the National Academy of Sciences (PNAS), reports the discovery of a method for making human collagen in the lab. The work is important because it opens a door to producing a material that can have broad use in medicine and replace the animal products that are now used but that can also harbor path...

Breast implants not associated with cancer risk, study reports

Wrinkled membranes create novel drug-delivery system

... tuned to deliver drugs at different rates. Chaieb reports his findings in the Feb. 17 issue of the journal Physical Review Letters. To make the capsules, Chaieb begins by confining a drug inside lipid bilayer membranes. Some of the lipids are then "sewn together" through a polymerization process. Cooling t...

Patients now surviving once-fatal immune disease

...ude and senior author of the report. "In fact, old reports we read stated that the vast majority of these patients have chronic lung disease by age 15. We and other physicians were quite surprised at how well these patients are doing with the proper care." XLA is a rare disease that is inherited through a ...

Brain differences could explain why males and females experience pain relief differently

...nta-based Center for Behavioral Neuroscience (CBN) reports that anatomical and functional differences in the brain may explain sex differences in the experience of pain and in the effects of certain drugs on pain.

Loosen leash on cancer protein 'watchdog,' researchers say

... systems don't survive gestation. Moreover, recent reports have suggested that high levels of p53 may accelerate aging. Having the wrong amount of p53 protein, therefore, leaves you with two potentially unappealing choices: Do you want to die early of cancer or die early from wearing your body out?" The sci...

All placebos not created alike

...lustrated in this study applied only to subjective reports from patients about their perception of pain and the severity of their condition.

Possible brain hormone may unlock mystery of hibernation

...n the blood of hibernating chipmunks. The team now reports evidence that the level of HPc in the brain increases at the onset of hibernation independently of changes in body temperature. Moreover, treatments that block HP activity in the animals' brains cuts hibernation short. "One of the most curious biolo...
