Title: Pieces rapportees absorbantes, procede permettant de les produire et utilisation
Inventor: PFLUEGER KLAUS
IPC: B32B27/08
Filed: 1997-06-27
Abstract: L'invention concerne une pièce rapportée absorbante pour emballages alimentaires dont la partie absorbant les liquides est un polymère superabsorbant qui absorbe et retient de manière durable des quantités importantes de liquide, à un niveau jamais atteint jusqu'à présent, même en cas de forte charge de pression. Ce polymère protège les aliments des dégradations bactériennes et empêche la contamination du produit emballé par des constituants solubles du polymère en migration. Cette combinaison de propriétés des superabsorbants utilisés est divisée par le quotient Q¿SAP 0,3? issu de la rétention après test dit du sachet de thé + absorption sous pression (AAP), ledit quotient étant égal à 0,3, exprimée par la quantité de parts Q¿SAP 0,3? solubles, qui s'élève au moins à 20. Les superabsorbeurs présentant ces propriétés sont obtenus par utilisation de combinaisons spéciales de réticulants. L'invention concerne en outre un procédé de production de pièces rapportées absorbantes de ce type, ainsi que leur utilisation dans des emballages alimentaires, comme substitut de glace et comme protection limitant le mouvement dans des emballages destinés au transport.

Filed: 1997-08-11
Abstract: La CD97 est un antigène induit par activation sur des leucocytes avec une région de transmembrane de couverture (7-TM) homologue à la superfamille des récepteurs de la sécrétine. Toutefois, contrairement à ce groupe de récepteurs d'hormones peptidiques, la CD97 présente une région extracellulaire étendue présentant trois domaines EGF à l'extrémité N-terminale, dont deux présentent un site de fixation du calcium. Les lymphocytes et les érythrocytes adhèrent spécifiquement à des cellules COS transfectées par CD97, adhésion bloquée par un anticorps monoclonal (mAb) dirigé contre la répétition consensus courte (SCR) N-terminale du facteur accélérant la décomposition (DAF, CD55), une protéine régulatrice de la cascade du complément. Les érythrocytes sans CD55, prélevés sur des patients présentant une hémoglobinurie paroxystique nocture (PNH) ou le phénotype Inab à CD55?-¿, n'adhèrent pas aux transfectants de CD97. L'invention présente des procédés et des moyens destinés à intervenir dans la liaison de CD97 et CD55, ce qui est particulièrement utile en médecine des hétérogreffes dans laquelle le CD55 est utilisé pour réguler négativement la voie d'activation du complément.

Abstract: An optical fiber device includes a polymeric optical fiber having a proximal end for coupling to a source of light, and a diffusing region. The polymeric optical fiber includes a core and a cladding around the core. The diffusing region includes a length of the polymeric optical fiber in which the cladding is partially removed to expose the core and in which the exposed core and the remaining cladding have a roughened surface for outwardly diffusing light carried through the polymeric optical fiber. The diffusing region is preferably formed by abrasion, for example by directing a particle jet at the optical fiber while rotating and translating the optical fiber with respect to the particle jet. The particle jet may include microscopic glass beads which roughen the optical fiber core. The density of scattering sites may be varied along the length of the diffusing region to produce a desired light output pattern. The optical fiber device is useful in medical application, including as a component of catheter or endoscopic systems.

Abstract: A method for call delivery to a called subscriber (B) in one or several telecommunications (= TK) networks (1, 2, 3) is characterized in that the called TK subscriber (B) has several different network accesses (11, 12, 13) that can be reached by the same dial number by a calling TK subscriber (A) and that a call, when this unique dial number is dialed by the calling TK subscriber (A), is forwarded in parallel to several network accesses (11, 12, 13) of the called TK subscriber (B). When the called TK subscriber (B) accepts the call at one of his network accesses (13), a corresponding return message releases the simultaneously pending call at his other network accesses (11, 12). Thus, an incoming call can be offered simultaneously to several different TK  network accesses of the called TK subscriber so that no significant time delay occurs due to successive processing of the routing list.

Title: Isotropic liquid detergent
Inventor: RODRIGUES KLEIN A
IPC: C11D3/37
Filed: 1999-06-23
Abstract: An isotropic liquid detergent composition comprising at least one surfactant and from about 0.1 to about 75 weight percent, based on the total weight of the liquid detergent composition, of a water-soluble or water-dispersible polymer having pendant acid functionality and a terminal fragment of a chain transfer agent, wherein the polymer is the polymerization product of a ethylenically unsaturated acid monomer and a C1 to C24 chain transfer agent. Unexpectedly, these polymers are compatible in isotropic liquid detergent formulations. When these polymers are used in a laundering process, they remove soil from textiles, inhibit soil redeposition onto textiles, and function as cobuilders by complexing metal ions present in hard water such as calcium and magnesium which otherwise may complex with the surfactants of a liquid detergent rendering the surfactants water-insoluble. Thus, the polymers exhibit a synergistic effect with surfactants of a liquid detergent to solubilize soil stains and suspend dirt particles in a laundering process.

Title: Prognostic protocol
Inventor: GRANDIS JENNIFER RUBIN
IPC: A61P35/00
Filed: 1998-08-28
Abstract: A cancer prognostic having particular utility in the prognosis of head and neck squamous cell cancer, in which the expression levels of either or both of Transforming Growth Factor Alpha (TGF-.alpha.) or Epidermal Growth Factor Receptor (EGFR) are assayed directly from a sample of tumor tissue. The expression level once quantitated is normalized as to standard, and the standardized expression level is compared to the prognostic threshold of about 83 % of standard for TGF-.alpha. or of about 23 % of standard for EGFR, or the corresponding upper threshold of the "low" tertile regardless of how calculated. Virtually all if not all patients demonstrating this low expression level survive at least five years after initial diagnosis, assuming completion of treatment with standard surgical tumor excision and radiation protocols for squamous cell head and neck cancer. Whether an individual patient's expression levels of TGF-.alpha. and EGFR fall inside or outside of this category signifies whether the patient is in a good or poor prognostic category, respectively, which in turn guides appropriate choice of therapy.
