Abstract: A cable sleeve system for bone fixation, comprising a cable, and a sleeve including a head for securing the cable and a piercing portion, wherein the piercing portion projects from a bottom face of the head substantially perpendicularly therefrom, and the head is provided with a bore extending in parallel with the bottom face for securing the cable therein, the head being adapted to be crimped to secure the cable therein. Because the sleeve can be made highly compact, it is possible to avoid undesirable side effects such as hemorrhage and inflammation due to irritations to the human body tissues which occurred frequently in the case of the cable securing method using the conventional cable grip.  <IMAGE>

Abstract: A method of hydrating nasal airway surfaces in a subject in need of such treatment comprises topically applying a sodium channel blocker to a nasal airway surface of the subject in an amount effective to inhibit the reabsorption of water by the surface. The channel blocker may be a pyrazinoylguanidine sodium channel blocker, such as benzamil, phenamil, amiloride, or a pharmaceutically acceptable salts thereof. The method may further comprise the step of topically applying a P2Y<SUB>2 </SUB>receptor agonist to a nasal airway surface of the subject in an amount effective to stimulate chloride secretion by the nasal airway surface. In a preferred embodiment, the sodium channel blocker is a covalent conjugate of a pyrazinoylguanidine sodium channel blocker and a non-absorbable carrier moiety (e.g., albumin, polyethylene glycol). Such compounds may also be administered to other mucosal surfaces where it is desired to inhibit the reabsorption of water.

Abstract: The invention relates to a process for manufacturing von Willebrand factor. This process comprises the selective adsorption of factor VIIIc on the gel of a first ion exchange chromatography column, the von Willebrand factor being contained in the non-retained fraction, and is characterised in that the non-retained fraction is treated so as to adsorb the von Willebrand factor selectively on the gel of a second chromatography column, the factor then being desorbed and being obtained with a very high purity. The invention enables a von Willebrand factor of very high purity, largely devoid of antihaemophilic factor VIIIc and of inactivators such as Tween and TNBP, as well as of the main plasm contaminants, to be obtained.

IPC: A61K39/145
Filed: 2009-01-28
Abstract: The present invention is based on the development of a dual promoter system (preferably a RNA pol I -pol II system) for the efficient intracellular synthesis of viral RNA. The resultant minimal plasmid-based system may be used to synthesize any RNA virus, preferably viruses with a negative single stranded RNA genome. The viral product of the system is produced when the plasmids of the system are introduced into a suitable host cell. One application of the system is production of attenuated, reassortant influenza viruses for use as antigens in vaccines. The reassortant viruses generated by cotransfection of plasmids may comprise genes encoding the surface glycoproteins hemagglutinin and neuraminidase from an influenza virus currently infecting the population and the internal genes from an attenuated influenza virus. An advantageous property of the present invention is its versatility; the system may be quickly and easily adapted to synthesize an attenuated version of any RNA virus. Attenuated or inactivated RNA viruses produced by the present invention may be administered to a patient in need of vaccination by any of several routes including intranasally or intramuscularly.

Title: Improved preparation of chalcone derivatives
Inventor: BERTRAND KARINE
IPC: C07C319/00
Filed: 2011-05-16
Abstract: The invention relates to methods for producing chalcone (1,3-diphenylprop-2-en-1-one) derivatives that have multiple substitutions on a phenyl ring. Intermediate chalcone derivatives are modified by Phase Transfer Catalysis (PTC) for introducing a substituted alkyl group that is provided by a sulfonic acid derivative on a phenyl ring already containing substituent groups on one or two carbon atoms adjacent to the carbon atom where a substituent group is being introduced. The methods of the invention allow producing efficiently, by either S-alkylation or O-alkylation, chalcones derivatives that are characterized for their biological activities that are intermediate compounds for producing molecules having such activities, or that can be used for generating libraries of compounds to be screened by means of in vitro and/or in vivo assays and establishing structure-activity relationships.
