Title: Antagonistes et agonistes de la cytokine
Inventor: LOPEZ ANGEL
IPC: A61K38/00
Filed: 1997-01-29
Abstract: La présente invention concerne un agent thérapeutique capable de se lier à la boucle F'-G' du domaine 4 de la chaîne βc commune du récepteur de GM-CSF, IL-3 et IL-5. L'acide aminé Tyr421, qui est situé dans la boucle F'-G, est critique dans la liaison à haute affinité et la stimulation de fonction de GM-CSF, IL-3 et IL-5 à la chaîne β¿c? commune de leurs récepteurs. D'autres récepteurs de cytokines présentent aussi des acides aminés hydrophobes dans des positions analogues et il est probable qu'eux aussi jouent un rôle central dans la liaison des cytokines correspondantes sur eux et dans la fonction de modulation. L'invention propose aussi des agents capables de se lier aux boucles F'-G', et qui devraient avoir une valeur thérapeutique.

Patent WO-0141321-A1 (WO)
Inventor: MCKEEN TRENT
IPC: H05K9/00
Filed: 2000-10-13
Abstract: In a superheterodyne receiver, energy can bypass a filter by magnetically coupling to a metallic radio frequency shield. This is especially a problem with small form factor devices in which the metallic radio frequency shield is positioned close to the filter. By using a ferrite-embedded element positioned betwen the filter and the RF shield, some of the undesired harmonics produced by the mixer can be dissipated into heat.

Patent CA-2021516-A1 (CA)
IPC: H04B10/142
Filed: 1990-07-19
Abstract: An amplitude-modulated vestigial-sideband, television channel sub-carrier multiplexed optical fiber transmission system includes a laser diode operating linearly throughout the desired range of multiplex frequencies. Such linear laser diode operation is accomplished by limiting leakage current within the laser diode to a very low level. The composite second-order distortion in the optical output signal from the laser diode is down typically 50 db from the video carrier for each channel. For some laser diodes that exhibit slow turn-on in the L-I characteristic, there is a point of inflection in the L-I curve. Operation with the laser biased at or near this point results in extremely linear performance, even though the laser may have insufficient blocking of leakage current to otherwise produce acceptable linearity.
