Brain tissue from the frontal cortex and hippocampal formation, taken at autopsy or biopsy from 7 patients with Alzheimer's disease, was studied by two methods of microanalysis. One case of Down's syndrome was also studied. Electron probe microanalysis of the frontal cortex and Ammon's horn of the hippocampus showed no aluminium in the various cell(More)
The lysosomes of several varieties of cells such as the tubular proximal cell of the kidney and the alveolar macrophage have the ability to concentrate and precipitate several elements inhaled in water-soluble form, usually as phosphate. The mechanism involved is attributed to the high acid phosphatase activity of lysosomes and can be considered as an in(More)
The RetroX is a new semi-implantable hearing aid which does not occlude the external ear canal. It consists of an electronic unit that plugs into a titanium tube which is implanted under the pinna so as to connect the retroauricular sulcus with the inside lumen of the external ear canal.

We propose a new audiometric test to assess French speakers' speech discrimination in noise. This soundfield test uses a standard cocktail-party background noise superimposed on Fournier's disyllabic word lists. The background noise is CD-recorded at constant 55 dB SPL. The discrimination score is measured at a signal-to-noise ratio of -5 dB, 0, and dB. In(More)
