Abstract: On a trouvé que l'administration de composés à base de .beta.-lactame, notamment des inhibiteurs de certaines peptidases bactériennes, pouvait produire des effets neurotropes importants chez des vertébrés à sang chaud, ces effets étant mis en relief, entre autres, par une attitude anxiolytique et anti-aggressive et une activité cognitive accrue, lesquelles sont supposées être induites par l'inhibition de la NAALADase neurogène et de l'activité enzymatique associée. On a trouvé que les antibiotiques à base de .beta.-lactame et les inhibiteurs de la .beta.-lactamase possédaient un pouvoir d'inhibition de la NAALADase, et que ces composés, capables de transport à travers la barrière hémato-encéphalique, constituaient des inhibiteurs efficaces de la NAALADase neurogène et possédaient des effets neuro-thérapeutiques importants. On peut utiliser les composés à base de .beta.-lactame dans le traitement de nombreuses pathologies associées aux anomalies du glutamate. L'invention concerne encore des procédés thérapeutiques d'utilisation de tels composés, ainsi que les formulations pharmaceutiques de ces composés.

Title: Thermoelectric temperature controlled drawer assembly
Inventor: ZIMMERMAN ROBERT C
IPC: F25B21/02
Filed: 2002-05-03
Granted: 2007-11-20
Abstract: A temperature controlled drawer assembly incorporates a thermoelectric device and a control system to selectively heat or cool the contents of a drawer which is selectively movable into and out of a cabinet designed to be part of an end table, such as a nightstand, or other cabinet remote from a household kitchen. In a cooling mode of operation, a fin, disposed in the cabinet, draws air from inside the drawer and blows the air over a cold side of a heat sink to cool the air. The treated air is blown through plenums, back into the drawer.  At the same time, heat is drawn away from the cold side and directed out of the cabinet. The current through the heat sink may be reversed to flip the cold and hot sides of the heat sink to enable the contents of the drawer to be heated.

Title: Process for preparing carbon nanotubes
Inventor: DESILETS SYLVAIN
IPC: B01J19/12

Granted: 2009-02-03
Abstract: Carbon nanotubes are formed on carbon paper by first depositing a metal catalyst on the carbon paper, and passing a feedstock gas containing a source of carbon over the substrate while applying an electrical current thereto to heat the substrate sufficiently to generate a reaction between the catalyst and the feedstock gas. Alternatively, inert gas under pressure is passed through a tubular metal cathode while passing an electric current through the cathode to produce a plasma of fine catalyst particles which are deposited on a porous carbon substrate, and a feedstock gas containing a source of carbon is passed over the substrate to cause a reaction between the catalyst and the carbon source resulting in the formation of carbon nanotubes.
