Title: Apparatus and method for non-invasively monitoring a subject's arterial blood pressure
Inventor: VOSS GREGORY I
IPC: A61B5/022
Filed: 1999-07-15
Abstract: Apparatus is disclosed for non-invasively monitoring a subject's blood pressure, in which a pressure sensor assembly (14) that includes a pressure transducer (50) is compressed against tissue overlying an artery, with sufficient force to compress the artery. A motor (32) first servo control system optimizes the amount of artery compression, which occurs at a mean transmural pressure of about zero, by modulating one side of a lever arm (36) compressing the assembly against the tissue, creating a pressure signal indicative of transmural pressure. Since different pressure effects are realized according to the amount of artery compression, an appropriate control signal can be produced that provides for a second motor (34) to adjust the other side of the lever arm (36) to provide the optimum compression of the assembly into the tissue overlying the artery. The apparatus is optimally positioned over an artery by including an ultrasonic blood flow sensor configured to sense the flow of blood under the pressure transducer.

Inventor: HUBERT RENE S
IPC: C07K16/18
Filed: 1999-08-10
Abstract: L'invention concerne un nouveau gène ainsi que l'antigène tumoral de celui-ci, sécrété, codé et dénommé BPC-1; elle concerne également des méthodes et compositions diagnostiques et thérapeutiques, utiles dans la gestion de divers cancers exprimant BPC-1, notamment le cancer de la prostate et celui de la vessie. Dans des tissus normaux humains, BPC-1 n'est exprimé que dans certains tissus du cerveau. Cependant, BPC-1 est exprimé à des niveaux élevés dans les cellules du cancer de la prostate, de même que dans les cellules du cancer de la vessie. La structure de BPC-1 comprend une séquence de signaux ainsi qu'un domaine CUB. La protéine BPC-1 est sécrétée. Une évidence expérimentale préliminaire suggère que BPC-1 est directement impliqué dans l'oncogenèse ou le maintien du phénotype transformé de cellules cancéreuses exprimant BPC-1. BPC-1 semble également se lier spécifiquement à une protéine cellulaire exprimée dans les cellules du cancer de la prostate ainsi que dans d'autres cellules.

Title: System and method of making a modified atmosphere package
Inventor: DELDUCA GARY R
IPC: B65B31/06
Filed: 1999-10-08
Abstract: A packaging system and method utilizes a modified atmosphere package (10) including an outer (12) and inner package (14). The outer package includes a non-barrier portion (16) substantially permeable to oxygen, while the inner packet (14) is substantially impermeable to oxygen. After a food product such as raw meat (26) is placed within the inner package (14), the inner package is sealed and then inserted into the outer package without sealing the outer package (12) so as to create a pocket (13) between the inner and outer packages. The system and method first employ an oxygen reduction technique such as evacuation, gas flushing, and/or scavenging to quickly reduce the oxygen level in the pocket to a first non-zero level, and to employ an activate oxygen scavenger (28) to further reduce the oxygen level to zero percent after the package (14) is sealed. The oxygen scavenger (28) is activated with an oxygen uptake accelerator to increase the rate at which the oxygen is absorbed. The oxygen scavenger (28) is positioned external to the inner package to aggressively absorb any residual oxygen with the pocket and the inner package and absorb any oxygen that might seep into the modified package (10).
