چکیده
Coronary heart disease is the leading cause of death in the United States. An alternate therapy is needed to treat the 180,000 people each year who require coronary artery bypass surgery. Several different strategies have been explored to develop vascular graft substitutes, but so far all have proven unsatisfactory. Current engineered vessels lack sufficient strength or require many weeks to be fully functional. We propose an innovative solution using patient-derived stem cells obtained from fat tissue. Cells will be seeded onto a biological collagen sheet derived from the human placenta, and rolled into a tube with appropriate diameter. The tubular construct will be mounted in a perfused bioreactor to simulate the mechanical conditions of native vessels. This project has the potential to provide off-theshelf availability of replacement blood vessels.

Φ-derivable Approximations in Gauge Theories *
We discuss the method of Φ-derivable approximations in gauge theories. There, two complications arise, namely the violation of Bose symmetry in correlation functions and the gauge dependence. For the latter we argue that the error introduced by the gauge dependent terms is controlled, therefore not invalidating the method.
متن کاملShell Interactions for Dirac Operators: On the Point Spectrum and the Confinement
Spectral properties and the confinement phenomenon for the couplingH+V are studied, where H = −iα ·∇+mβ is the free Dirac operator in R and V is a measure-valued potential. The potentials V under consideration are given in terms of surface measures on the boundary of bounded regular domains in R. A criterion for the existence of point spectrum is given, with applications to electrostatic shell ...
