The Board of Directors of City Trusts of the city of Philadelphia honored three researchers last month for inventions that have contributed to the "comfort, welfare, and happiness" of mankind. The three were given John Scott Awards, consisting of a copper medal and a $10,000 prize. An unshared award went to Barry J. Marshall, a 1995 Lasker laureate and a clinical associate professor of internal medicine at the University of Virginia, for discovering the bacterium Helicobacter pylori and its rol
The Infection-Chronic Disease Link Strengthens

Infection" is usually associated with an oozing sore, a bout with the flu, or an outbreak in some exotic place. But infectious organisms lie behind many chronic illnesses too, and an increasingly molecular approach to diagnosis is clarifying some of these relationships. An invited panel discussed "The Infectious Etiology of Chronic Diseases" at the second International Conference on Emerging Infectious Diseases, held in Atlanta July 16-19. Chronic diseases take a huge toll. "In the [United St

Inflammation's infamy

Courtesy of Keith Crutcher IMMUNITY IN MIND: Cultured microglial (N9) cells (red) on a tissue section containing an Alzheimer plaque (green). There is continuing controversy about whether these types of inflammatory cells are responding to plaques or causing them. A finger catches the sharp edge of an envelope; a noseful of tree pollen is accidentally inhaled; the latest virus finds host after human host. In all cases the assaulted body reacts through inflammation, a well known, but not

Microcolumns Collapse in Alzheimer's Brain Tangles and plaques are hallmarks of the Alzheimer's brain. Thanks to a technique borrowed from statistical physics, researchers from Boston University, the University of Minnesota, and Bar-Ilan University in Israel have quantified another sign: microcolumns of 11 neurons that are noticeably diminished in the Alzheimer's brain, and less so in the related condition Lewy body dementia. Using brains from a brain bank, the researchers probed a part of the
