Abstract: A skateboard deck comprising an elongate, fiber-reinforced thermoplastic injection molded body having top and bottom surfaces and including: a pair of spaced truck attachment bases integrally formed on the bottom surface and each associated with a respective end of said body; a substantially closed-loop, integral torsion member formed on the bottom surface of the body in a space between said truck attachment bases; and a pair of longitudinal stiffening ribs each formed integrally with the body, said truck attachment bases and said torsion member, said stiffening ribs and body being positively cambered whereby the body substantially flattens out under load in use.

Abstract: Disclosed is a method for producing cardiomyocytes in vivo by administering to the heart of an individual a cardiomyocyte producing amount of mesenchymal stem cells. These cells can be administered as a liquid injectible or as a preparation of cells in a matrix which is or becomes solid or semi-solid. The cells can be genetically modified to enhance myocardial differentiation and integration. Also disclosed is a method for replacing cells ex vivo in a heart valve for implantation.
