标 题 :Chondrocyte media formulations and culture procedures
发明人：MCPHERSON JOHN M; YAEGER PETER C; BROWN MARIE E; HANLON JAMES G; BINETTE FRANCOIS
权利人:GENZYME CORP
摘要:One object of the present invention is based upon the development and use of a serum-free defined cell culture medium comprising a supplement mixture, a component mixture, a vitamin mixture, an inorganic salt mixture and amino acid mixture that avoids the problems inherent in the use of serum. In particular, the defined medium is useful in culturing fibroblasts, especially chondrocytes. Another object of the present invention is to claim a method of enhancing the differentiation of chondrocytes and enhancing the synthesis of a cartilage specific matrix using tumor growth factor beta (TGF-β). Another object of the present invention is to claim a method of enhancing the differentiation of chondrocytes using the combination of TGF-βand IGF.

标题 :Nutrient compositions and methods for sustenance and promotion of positive metabolic energy levels in a targeted manner
发明人：BOLDT MATTHIAS
摘要:Nutrient compositions and methods that sustain and promote positive metabolic energy levels in a targeted manner are disclosed. Methods utilize endogenous energy stores (fat oxidation), increase use of those stores (increasing transport rate), increase available energy (increasing the ability to perform ADP to ATP phosphorylation,) as well as decrease catabolism and increase protein synthesis. Compositions are also disclosed, and include Mono- or Dicreatine-HMB salt; Putrescine Dihydrochloride; Alanine; L-Glutamine, which may be combined with Alanine in a 1:2 to 2:1 molecular ratio; Trimethylglycine; and Guanidinopropionic Acid.

标 题 :Polyamine transport inhibitors
发明人：POULIN RICHARD; AUDETTE MARIE; CHAREST-GAUDREALT RENE
权利人:UNIV LAVAL; ILEX ONCOLOGY INC; POULIN RICHARD; AUDETTE MARIE; CHAREST GAUDREALT RENE
摘要:The application discloses synthetic derivatives of original polyamines in which a carbon atom to the original polyamine comprises an amide group inhibits the e cellular uptake of a natural polyamine by specifically binding a cellular transporter for a natural polyamine . The synthetic derivatives are used to inhibit the activity of a natural polyamine transporter, in the treatment of disorders involving unrestrained cell proliferation and/or differentiation where control of polyamine transport is required When used in combination with a n inhibitor of polyamine synthesis.
