Fighting Alzheimer's by defusing a death receptor

A receptor that incites cell suicide also promotes the accumulation of β-amyloid plaques in Alzheimer's disease (AD), as He et al. show on page 829. In mice prone to the brain buildups, eliminating the receptor cut the number of plaques and spared memory. The results point to new treatments for the incurable disease. As plaques of β-amyloid collect in the brains of AD patients, large numbers of...

EHPnet: Mines, All Mines

The presence or absence of an oestrogen receptor-related antigen in breast tumours has been examined histochemically using a monoclonal antibody ('D59 Coffer & King, 1981). In frozen sections, fixed either by the method of Tamura et al. (1980) or in methanol, staining was apparent in 14/24 (58%) and 22/26 (85%) of the breast cancers respectively. In paraffin sections fixed in ethanol, staining ...

Fighting poverty, fighting AIDS.

J effrey sachs is an economist, not an evangelist. But give the man 10 minutes behind a microphone, and a scholarly symposium starts to feel like a revival meeting. “Ladies and gentlemen,” he tells a hushed hall after describing how AIDS sufferers die in Malawi for want of $1-a-day drugs, “this plague is exploding. Its consequences will make the world quake. Rich countries could stop the devast...

The goal of this thesis is to design algorithms that run with better complexity when compiling or parallelizing loop programs. The framework within which our algorithms operate is the polyhedral model of compilation which has been successful in the design and implementation of complex loop nest optimizers and parallelizing compilers. The algorithmic complexity and scalability limitations of the...
