1. Hemocompatibility of materials for use in prosthetic heart valves
Abstract : Thromboembolism (valve thrombosis and systemic embolism) is the main drawback of mechanical heart valve prostheses. The patients carrying these valves have to be subjected to life-long anticoagulant therapy to reduce thromboembolism. READ MORE

2. Epidemiological studies of bioprosthetic aortic valves
Abstract : Background: The use of bioprosthetic valves is common and offers a prosthetic option that does not require anti-coagulant therapy, but with shorter valve longevity compared to mechanical prostheses. Valve model selection might influence the long-term performance of the prosthesis. READ MORE

3. Studies on glycosphingolipids in regenerative medicine
Abstract : Regenerative medicine, including stem cell based therapies and xenotransplantation, is a new and developing field that aims to restore normal function in end stage cell/organ failure. However, in therapeutic settings involving transfer of cells with a different genetic background, these cells will expose the recipient to non-self cell surface antigenic determinants that may evoke an immune response and subsequent graft damage.
