权利人:MERCK PATENT GMBH
摘要:Use of an aqueous or aqueous-alcoholic extract (A) of Bauhinia is claimed to make a composition for cosmetic or pharmaceutical treatment of skin and hair. Use of an aqueous or aqueous-alcoholic extract (A) of Bauhinia is claimed to make a composition for: (a) care, preservation or improvement of the general condition of the skin or hair; (b) prevention and/or inhibition of the aging process for human skin or hair; (c) for promoting healing of wounds; (d) for prevention and/or treatment of skin diseases associated with abnormal keratinization, and (e) for prevention and/or treatment of all malignant or benign growths of the dermis or epidermis. An independent claim is also included for a composition containing (A). ACTIVITY : Dermatological; Vulnerary; Antiseborrheic; Antipsoriatic; Cytostatic; Antiinflammatory; Virucide. MECHANISM OF ACTION : Protein glycosylation inhibitor. In a test, human fibroblasts were cultured in the presence of Vitamin C to stimulate collagen synthesis, then lysed and labeled with tritiated glucose for 15 days, Proteins were removed, extraction and precipitation were carried and the amount of bound glucose measured by liquid scintillation counting. Addition of an aqueous-alcoholic extract of Bauhinia fortificata (0.03 mg/ml), reduced protein glycosylation to 55% of that in a control.

权利人:UNIV NORTHWESTERN
摘要:Spherical Nucleic Acids (SNAs) are chemically well-defined nanoscale architectures comprised of nucleic acids densely arranged around a spherical nanoparticle core in a highly oriented fashion. SNAs are highly modular structures produced by chemical synthesis and programmed assembly, allowing for their rapid modification to incorporate novel viral antigens. The present disclosure provides a SNA comprising (a) a nanoparticle core; (b) a shell of oligonucleotides attached to the external surface of the nanoparticle core, the shell of oligonucleotides comprising one or more immunostimulatory oligonucleotides; and (c) a viral antigen encapsulated in the nanoparticle core.

摘要:A composition for improving muscle metabolism in a subject and methods for manufacturing and using same. Embodiments include compositions having an extract of Rhaponticum and an extract of Rhodiola . An extract of Rhaponticum may include amounts of ecdysterones including 20-hydroxyecdysone. An extract of Rhodiola my include salidrosides and rosavins, including rosavin. Suitable ingestion dosages of the composition may be operable to increase protein synthesis and reduce protein proteolysis in a subject.
