1. Noninvasive haemodynamic evaluation of aortic valve prostheses : Doppler echocardiographic studies at rest and during exercise
Sammanfattning : The present series of investigations was designed to supply information on in vivo pressure-flow relationships and to analyse the incidence of regurgitation in different heart valve prostheses in the aortic position. Patients and methods: The study population comprised 185 patients with mechanical Björk-Shiley Monostrut prostheses, 54 patients with Biocor stented porcine bioprostheses, 50 patients with extended Biocor stentless bioprostheses and 59 patients with cryopreserved aortic homografts.

3. Quantum Chemical Modeling of Dye-Sensitized Titanium Dioxide : Ruthenium Polypyridyl and Perylene Dyes, TiO2 Nanoparticles, and Their Interfaces
Sammanfattning : Quantum chemical calculations have been used to model dye-sensitized nanostructured titanium dioxide systems that can be used in solar cells for solar energy to electricity conversion. Structural, electronic and spectral properties of isolated dyes and both bare and dye-sensitized TiO2 have been calculated with density functional theory, providing detailed information about both the separate parts and the dye-TiO2 interface.

4. Effects of immunosuppressive drugs on human adipose tissue metabolism
Sammanfattning : The immunosuppressive agents (IAs) rapamycin, cyclosporin A and tacrolimus, as well as glucocorticoids are used to prevent rejection of transplanted organs and to treat autoimmune disorders. Despite their desired action on the immune system, these agents have serious long-term metabolic side-effects, including dyslipidemia and new onset diabetes mellitus after transplantation. LÄS MER
