NIH scientists target future pandemic strains of H5N1 avian influenza
...y, samples of existing influenza virus strains are isolated and then grown inside eggs or in cell cultures. The virus is then collected, inactivated, purified and added to the other components of the vaccine. A flu shot prompts a persons immune system to detect pieces of the inactivated virus present in th...Michigan-CDC study supports value of social restrictions during influenza pandemics

...opper and zinc so close together. Her laboratory isolated and characterized the enzyme, but Valentine was less interested in its biological properties than in the inorganic chemistry. She was more interested, for example, in how the protein influenced the reactivity of the copper or zinc, or how the copper ...Aging stem cells in mice may hold answers to diseases of the aged, Stanford study finds
...ress this, in the second set of experiments, Rossi isolated stem cells from the bone marrow of normal young and old mice, then stained those cells with a chemical that clings to a protein that's associated with DNA damage. This protein can act as a flag to highlight nearby DNA damage. What he found is that ...Blocking stress protein decreases Alzheimer's peptide in mice
...Csernansky and Dong showed that raising them under isolated conditions in smaller cages accelerated the deposition of brain plaques and declines in cognitive ability. Brain plaques are believed to be a primary cause of the memory loss and other mental damage inflicted by Alzheimer's disease. They are mostly c...Exploring better ways to determine when to change the course of treatment

Since we can protect against the enzyme activation with both chelators and antioxidants, that means a few different types of activation are likely to occur, depending on the toxin."
