摘要:
Un nouveau polypeptide qui présente une affinité de liaison avec le récepteur p185HER2, appelé héréguline-alpha, a été identifié et purifié à partir de cellules humaines cultivées. Des séquences d'ADN codant des polypeptides d'héréguline additionnels, et appelés héréguline-alpha, héréguline-beta1, héréguline-beta2, héréguline-analogue au beta2 et héréguline-beta3, ont été isolées, séquencées et exprimées. L'invention décrit ainsi des séquences d'acide nucléique codant les séquences d'aminoacide d'hérégulines, et pouvant être utilisées pour la production d'hérégulines par recombinaison. On décrit en outre les séquences d'aminoacides d'hérégulines et des procédés de purification pour celles-ci. Les hérégulines et leurs anticorps peuvent être utilisés comme agents thérapeutiques et dans des procédés diagnostiques.
摘要:
An embeddable corrosion rate meter (ECRM) for detecting and measuring corrosion in metal and concrete structures comprises an electrochemical cell with an ECRM sensor circuit (20). Circuit (20) includes at least one working electrode (10) evenly spaced from counter/reference electrode (12) with the separation distance between the electrodes determining an electrolyte medium resistance. Circuit (20) also includes a current source generated by power source (28) connected through different resistances RI (26) to Rn (24). A first selector is used in applying current through each or the plurality of resistances to working electrode (10) and a second selector (16) selects a duration of the current pulse. Current is applied between the electrodes through galvanostat (22) and polarization of working electrode (10) is measured by voltmeter/A-D converter (18) connected via link (34). The voltmeter has an input impedance greater than a billion ohms. An external reader-head with power link (32) powers circuit (20) and reads and transfers corrosion measurement data via data link (36) to computer (30).
摘要:
The present invention concerns long half-life derivative of the obesity protein OB. The invention specifically concerns OB protein-immunoglobulin chimeras and polyethylene glycol (PEG)-OB derivatives, which have extended half-life as compared to the corresponding native OB proteins. The invention further relates to methods for appetite and/or weight reduction and for treating other physiological conditions by using the long half-life derivatives of OB.

摘要:
Chimeric heteromultimer adhesins that bind the ligand of natural heteromultimeric receptors and uses therefor are disclosed. The chimeric molecules of the heteromultimer adhesins comprise an extracellular domain of a heteromultimeric receptor monomer and a multimerization domain for the stable interaction of the chimeric mollecules in the adhesin. Specifically disclosed are heteromultimeric adhesins comprising the extracellular domains of ErbB2 and ErbB3 or ErbB2 and ErbB4. The chimeric ErbB heteromultimer adhesins of the present invention are useful as competitive antagonists or agonists of a neuregulin for the treatment of diseases such as various cancers.
