IPC: A61P11/00
Filed: 2002-04-15
Abstract: The equilibrium between G actin and F actin is shifted towards the F actin confirmation with compounds such as the ionic form of magnesium or potassium.  The higher amount of F actin decreases the inhibition of nucleases such as DNAse I by monomeric G actin. The increased performance of the nuclease results in better treatment of patients suffering from cystic fibrosis or other diseases associated with viscous mucus.

Patent CA-2445171-A1 (CA)
Inventor: TAM BETTY
IPC: C07K14/71
Filed: 2002-04-24
Abstract: La présente invention porte sur une protéine de liaison du TGF-.beta.1 appelée r150. Cette protéine possède une ancre GPI contenue dans r150 et non sur une protéine étroitement associée de façon à fixer le TGF-.beta.1 ayant une affinité comparable à celles des récepteurs de signalisation. De plus, la forme (soluble) libérable de cette protéine fixe le TGF-.beta.1 indépendamment des récepteurs de type I et II. La forme soluble inhibe la liaison du TGF-.beta. à son récepteur. L'invention met également en évidence la libération de r150 de la surface de la cellule par une phospholipase C endogène. L'invention porte également sur la création d'une lignée cellulaire de kératinocytes humains mutants avec un défaut dans la synthèse de GPI qui présente une expression réduite de r150. Les résultats obtenus utilisant ces kératinocytes mutants donnent à penser que la forme ancrée de la membrane de r150 est un modulateur négatif des réponses de TGF-bêta. A travers les recherches et après avoir constaté que r150 forme un complexe hétéromère avec les récepteurs de signalisation, il nous est également donné à penser que ce récepteur accessoire dans sa forme soluble ou ancrée de la membrane peut antagoniser des réponses de TGF-.beta. dans les kératinocytes humains. Des expériences avec des mutants ont confirmé que l'activité de TGF.beta.1 peut être modulée lorsque l'expression du récepteur accessoire r150 est <= silencé >=. L'invention porte, en outre, sur des séquences complètes d'acide nucléique et des séquences réduites d'acides aminés. L'acide nucléique cloné par r150 a été utilisé pour étudier la surexpression de r150. Lorsque le gène r150 est surexprimé, les réponses de TGF.beta. sont accrues. r150 et ses dérivés ou précurseurs (fragments, variants et acides nucléiques les codant) s'avèrent avoir une grande utilité clinique, sachant que TGF.beta.1 est une importante cytokine.

Title: Method and apparatus for identifying heart rate feature events
Inventor: GLAUDE MICHAEL C
IPC: G06F19/00
Filed: 2003-10-31
Abstract: A method and apparatus for segmenting a heart rate signal to identify heart rate feature events are provided. A heart rate signal including a sequence of sample points is received. The heart rate signal is processed to generate a set of segments.  Each segment is formed by enclosing a portion of the heart rate signal in a respective bounded area commencing at a start sample point and terminating at an end sample point of the heart rate signal. The sample points between the start sample point and end sample point lie within the bounded area. The set of segments are then processed to generate a plurality of sections, each section being indicative of a heart rate feature. The heart rate feature is selected from the set consisting of an acceleration event, a deceleration event and a baseline event. A signal indicative of the plurality of sections is then released.

Title: Increasing electro-gene transfer of nucleic acid molecules into host tissue
Inventor: LA MONICA NICOLA
IPC: A61K31/7088
Filed: 2002-11-21
Abstract: A method of delivering a pharmaceutical agent, such as a nucleic acid molecule, to a vertebrate host is disclosed which comprises combining the synergistic steps of electrical stimulation with administration of a biologically active amount of hyaluronidase. Additionally, formulations whic h comprise hyaluronidase and a pharmaceutical agent, such as a nucleic acid molecule, are disclosed. The hyaluronidase preparation is preferably administered prior to or simultaneous with the pharmaceutical agent and in conjunction with an applied electrical stimulation, thus affecting increased transfer of the population of a pharmaceutical agent into the target tissue when compared to the affect of electrical stimulation alone. The combination of hyaluronidase administration and electrostimulation results in a substantial increase in the transfer of the pharmaceutical agent, such as a nucleic acid molecule, to the target vertebrate host tissue.

Title: Cytotoxic cyplasin of the sea hare, aplysia punctata, cdna cloning and expression of bioreactive recombinants
Inventor: PETZELT CHRISTIAN
IPC: A61K38/00
Filed: 2002-12-18
Abstract: Described is a nucleic acid coding for a protein called "cyplasin" that shows a preferential toxicity to autonomously growing mammalian cells. Cell death induced by this protein differs from both apoptosis and necrosis. An intracellular cell death which occurs when recombinantly preparing cyplasin in cell cultures can be avoided by removal of the secretion signal in the cyplasin sequence. This modification makes it possible to express the cyplasin in a mammalian cell culture which is preferable with regard to the glycosylation pattern of the obtained protein. Thus, the present invention also relates to a method of recombinantly producing a protein in eukaryotic cells, preferably mammalian cells, which is cytotoxic for said cells when applied externally.
