Abstract:
Bioscaffoldings formed of hydrogels that are crosslinked in situ in an infarcted region of the heart (myocardium) by a Michael's addition reaction or by a disulfide bond formed by an oxidative process are described. Each of the bioscaffoldings described includes hyaluronan as one of the hydrogel components and the other component is selected from collagen, collagen-laminin, poly-1- lysine, and fibrin. The bioscaffolding may further include an alginate component. The bioscaffoldings may have biofunctional groups such as angiogenic factors and stem cell homing factors bound to the collagen, collagen-laminin, poly-1- lysine, or fibrinogen hydrogel component. In particular, the biofunctional groups may be PRl 1, PR39, VEGF, bFGF, a polyarginine/DNA plasmid complex, or a DNA/polyethyleneimine (PEI) complex. Additionally, the hydrogel components may be injected into the infarct region along with stem cells and microspheres containing stem cell homing factors. The bioscaffolding may be formed on a stent or a cardiac medical device.

Abstract:
A method for separating a Ill-nitride layer from a substrate. This is done by fabricating a detachment porous region between the Ill-nitride layer and the substrate through etching. The porous region allows for easy detachment of the Ill-nitride layer from the substrate. Active layers for electronic and optoelectronic devices can then be grown on the Ill-nitride layer.

Abstract:
The present invention provides methods of, and pharmaceutically-acceptable/veterinary-acceptable compositions suitable for, treating the T-cell and/or B-cell mediated autoimmune disease, multiple sclerosis, in human beings and the lower animals, respectively, by the administration to them of: (i) myelin oligodendrocyte glycoprotein (MOG); or (ii) a MOG-like protein; or (iii) an immunodominant region of MOG or MOG-like protein, in particular, an immunodominant epitope of MOG or MOG-like protein; or (iv) an anti-idiotypic antibody to a protein or peptide of (i) to (iii); or (v) monoclonal anti-idiotypic antibodies to a protein or peptide of (i) to (iii). The present invention further provides diagnostic agents, methods and kits for detecting multiple sclerosis or other T-cell and/or B-cell mediated autoimmune diseases in humans or lower animals. The present invention still further provides nucleotide sequences that code for human MOG or human MOG-like protein or an immunodominant region of human MOG or an immunodominant epitope of human MOG, as well as embracing human MOG or human MOG-like protein or an immunodominant region of human MOG or an immunodominant epitope of human MOG, obtained by standard procedures for protein synthesis or by recombinant DNA techniques.
