They will be presented according to the following schedule:
14:00 - 15:00
The use of platelet lysate in biomaterial research
Prof. Ólafur E. Sigurjónsson
Platelet lysate is a revolutionary bioproduct enabling efficient cell culturing under animal serum-free conditions for research and clinical applications. The list of approved cell therapies for patients has grown over the past decade, when the first one was approved. The most advanced ones involve the collection, expansion and engineering of patients' cells before being implanted back. However, the current state of the art for culturing these valuable cells mostly involves the use of serum inhumanely extracted from calf foetuses (FBS). This is a high-risk practice because of cross-species immune reactions (which can be lethal) and the transmission of animal borne diseases. Here I will discuss the use of platelet lysate from expired platelet concentrates in tissue engineering and biomaterial research.
15:00 - 16:00
Analysing bone mineral density in the proximal femur in total hip arthroplasty
Dr. Magnús Kjartan Gíslason
When deciding upon to carry out a total hip arthroplasty the surgeon needs to determine the type of implant used and how to fixate it. For the fixation it is possible either to use bone cement or to use so called press fitting, where the prosthesis is hammered into the femoral canal and the fixation is dependent on the interference forces between the prosthesis and the bone. Patients undergoing press fitting need to have a good mechanical strength in their femurs as the high impact forces during surgery may lead to periprosthetic fracture. The press fitting method has improved benefits long term for the patients, as revision surgery is easier to carry out than for the cemented fixation. This project studies the bone quality and the material distribution of subjects undergoing primary total hip arthroplasty in Iceland. Analysis was carried out on the three dimensional bone mineral density distribution in various regions of the proximal femur to determine whether or not the patient is a candidate for press fitting fixation.
16:00 - 17:00
From medical imaging to surgical planning: new directions for bone and muscle assessment
Prof. Paolo Gargiulo
This seminar outlines the methods and applications of X-ray Computed Tomography (CT) imaging to analyze soft tissue, bone and skeletal muscle density and volume in the context of modern challenges in the field of translational myology. The approaches described here use medical imaging processing techniques and computational methods to: quantify muscle morphology, illustrate changes with 3D models, develop numerical profiles specific for each individual, and assess muscle and bone changes due to targeted medical treatment. Applications of these methodologies are employed: to depict subject specific muscle profiling associated with age, to illustrate and quantify muscle degeneration and its partial reversal via Functional Electrical Stimulation (FES), and to highlight recovery following total hip arthroplasty (THA). The seminar will also describe new directions for surgical planning based on patient specific imaging and 3D modelling.
