权利人:UNIV LOUISIANA STATE; BULGARIAN ACADEMY OF SCIENCES
摘要:A catalyst useful in the conversion of nitrogen oxides or in the synthesis of nitriles or imines from amines, formed by preparing an intimate mechanical mixture of a copper (II)-containing species, such as CuO or CuCl 2 , or elemental copper, with a zeolite having a pore mouth comprising 10 oxygen atoms, such as ZSM-5, converting the elemental copper or copper (II) to copper (I), and driving the copper (I) into the zeolite.

标 题:Implantable or insertable medical device resistant to microbial growth and biofilm formation
发明人：MILLER KATHLEEN M; BUCAY-COUTO WEENNA; LI JIANMIN
权利人:BOSTON SCIENT SCIMED INC
摘要:Disclosed are implantable or insertable medical devices that provide resistance to microbial growth on and in the environment of the device and resistance to microbial adhesion and biofilm formation on the device. In particular, the invention discloses implantable or insertable medical devices that comprise at least one biocompatible matrix polymer region, an antimicrobial agent for providing resistance to microbial growth and/or a microbial adhesion/biofilm synthesis inhibitor for inhibiting the attachment of microbes and the synthesis and accumulation of biofilm on the surface of the medical device. Also disclosed are methods of manufacturing such devices under conditions that substantially prevent preferential partitioning of any of said bioactive agents to a surface of the biocompatible matrix polymer and substantially prevent chemical modification of said bioactive agents.

标 题 :Multifunction “crown complexesâ€? from amino acids and peptides for skin and hair restoration
发明人：GUPTA SHYAM K
权利人:BIODERM RESEARCH
摘要:This invention relates to Schiff's bases derived from amino acids and hydroxyaryl alkyl ketones, or a plant extract containing the same, having general chemical structure in FIG. 1 for topical application. This invention also relates to certain metal complex of said Schiff's bases, which have a crown-like appearance in their three-dimensional chemical structure, as in FIG. 2 . The Schiff's bases and their metal complexes of the present invention are useful for the modulation of metal-activated enzymes and metalloenzymes, such as Phenylalanine Hydroxylase, Tyrosine Transaminase, Phenylalanine Transaminase, Tyrosinase, various MMP (Matrix metalloproteases), Superoxide dismutase, 5-Alpha Reductase, and citrate lyase. These are further suitable for multifunctional topical methods for skin whitening, skin wrinkles reduction, skin antiaging, collagen synthesis, acne control, hair loss prevention, hair graying control, and facial oil control.
