Abstract: Provided herein is a method for predicting the probability of having or developing a non-fusion, wherein said method comprises determining the frequency of a subpopulation of CD8+ T cells selected from CD8+CD57+, CD8+CD28? and CD8+CD57+CD28? in a sample obtained from a patient. Also provided herein is a system for predicting the probability of having or developing a non-fusion.

Abstract: The present invention relates to a method for predicting the probability of having or developing a non-fusion, wherein said method comprises determining the frequency of a subpopulation of CD8+ T cells selected from CD8+CD57+, CD8+CD28? and CD8+CD57+CD28? in a sample obtained from a patient. The invention further relates to a system for predicting the probability of having or developing a non-fusion.

Abstract: The present invention relates to a sheet or tubular structure consisting of biocompatible material, which is elastic and comprises at least one biologically active substance in at least one region and to a sheet or tubular structure, which comprises at least one biologically active substance release-modifying agent in at least one region as well as an implant covered at least partially by the sheet or tubular structure of the invention. The present invention further provides a method and an apparatus for producing, and preferably customizing and/or optimizing, the sheet or tubular structure of the invention. The sheet or tubular structure of the invention can be customized/optimized before implantation in the operating room.
