1. 1. Modifying xenogeneic immune recognition and engraftment by genetic engineering

   Författare :Zhong He; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Xenotransplantation; gene therapy; gene transfer; endothelium; promoters; monocytes; NK cells; alpha-Gal; lentivirus vectors; pancreatic islets;

   Sammanfattning : Transplantation using xenogenic organs, tissues and cells (i.e. xenotransplantation) is a potential solution to the shortage of those from human sources. Vascular endothelial cells (ECs) are the most immediate barrier between the xenogeneic donor organ and the host defense systems. LÄS MER

3. 2. On some Numerical Methods and Solution Techniques for Incompressible Flow Problems

   Författare :Xin He; Maya Neytcheva; Zhong-Zhi Bai; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Sammanfattning : The focus of this work is on numerical solution methods for solving the incompressible Navier-Stokes equations, which consist of a set of coupled nonlinear partial differential equations.In general, after linearization and finite element discretization in space, the original nonlinear problem is converted into finding the solutions of a sequence of linear systems of equations.
