A mutant allele of the chemokine receptor CCR5 gene (CCR5-Delta32), which confers resistance to HIV-1 infection, is believed to have originated from a single mutation event in historic times, and rapidly expanded in Caucasian populations, owing to an unknown selective advantage. Among other candidates, the plague bacillus Yersinia pestis was implicated as a(More)

Protein expression in foetal brain with or without chromosome 21 trisomy (Down's syndrome) was analyzed by two-dimensional gel electrophoresis and mass spectrometry. Data generated by in-gel digestion and matrix-assisted laser desorption/ionization mass spectrometry allowed identification of 40 proteins. Most of these are common to syndrome and healthy(More)
BACKGROUND AND PURPOSE Hypothermia has been shown to be neuroprotective in a variety of clinical settings. Unfortunately, poor delivery techniques and insufficient data in appropriate preclinical models have hampered its development in human stroke. To address these limitations, we have devised a 10F intravascular catheter capable of rapid systemic cooling(More)
