Abstract: A hard carbon coating and a method to improve its adhesion on components and tools subjected to high loads or subjected to extreme friction, wear and contact with other parts. The metal carbide transition layer is situated between the adhesivepromoting layer deposited directly onto the substrate surface and a top hard carbon coating. The metal carbide transition layer has a denser microstructure and improved mechanical properties in order to resist failure by spalling.

Abstract: The present disclosure relates to a recombinant endothelial growth factor like 7 (EGFL7) peptide and uses thereof for treating graft-versus-host disease (GVHD).

Abstract: Compositions and methods for reducing or preventing graft-versus-host disease associated with allogeneic stem cell transplantation are described. A method includes harvesting hematopoietic cells from a patient with an immunologic disorder and harvesting hematopoietic cells from a donor. The harvested hemaptopoietic cells from the patient and the donor are mixed ex vivo for a period of time sufficient to activate lymphocytes within the hematopoietic cells harvested from the donor such that an immune reaction occurs and an activated portion and an unactivated portion is produced. A rhodamine B derivative is then added to the mixture of cells and the mixture is irradiated at a suitable wavelength and intensity for the selective destruction and/or inactivation of the activated portion without substantially affecting the unactivated portion or causing systemic toxicity in said patient. The irradiated cells are then infused into the patient.

Abstract: The present invention relates to the use of the photoactivable derivatives for the photodynamic treatment for the selective destruction and/or inactivation of immunologically reactive cells without affecting the normal cells and without causing systemic toxicity for the patient, wherein appropriate intracellular levels of said derivatives are achieved and irradiation of a suitable wavelength and intensity is applied.
