Abstract: A surgical system for detecting perfusion includes at least one surgical camera and a computing device. The at least one surgical camera is configured to obtain image data of tissue at a surgical site including first image data and second image data that is temporally-spaced relative to the first image data. The computing device is configured to receive the image data from the at least one surgical camera and includes a non-transitory computer-readable storage medium storing instructions configured to cause the computing device to detect differences between the first and second image data, determine a level of perfusion in the tissue based on the detected differences between the first and second image data, and provide an output indicative of the determined level of perfusion in the tissue.

Abstract: The invention relates to a method for producing stem cells having an increased development potential from somatic stem cells, wherein a tissue sample comprising somatic stem cells or a body fluid sample comprising somatic stem cells is taken from an organism, wherein from this tissue sample or body fluid sample as an option somatic stem cells are isolated and/or cultivated, and wherein the thus obtained somatic stem cells are treated with a substance modulating the methylation of the DNA of the cells or a substance modulating the acetylation of chromatin of the cells.

Abstract: A method for the prevention or reversal of islet cell transplant rejection, or for therapy for autoimmune diseases, is provided comprising administering compounds such as monoclonal antibodies, that bind specifically to CD40L and the CD4 receptor.

Abstract: A mixed chimeric immune system is created for a variety of treatments and techniques. Mixed chimerism is established in a recipient without significant risk of profound neutropenia or graft-versus-host-disease (GVHD) by administering a cell transplant from a donor to a recipient along with a conditioning treatment and an immune blockade treatment.
