    Abstract : Calcium phosphate cements (CPCs) are used as bone void fillers and as complements to hardware in fracture fixation. The aim of this thesis was to investigate the possibilities and limitations of the CPCs’ mechanical properties, and find out if these ceramic bone cements can carry application-specific loads, alone or as part of a construct.

    Abstract : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. READ MORE

  3. 3. Physical Properties of Acidic Calcium Phosphate Cements

    Author : Johanna Unosson; Håkan Engqvist; Cecilia Persson; Uwe Gbureck; Uppsala universitet; []

    Abstract : The gold standard for bone replacement today, autologous bone, suffers from several disadvantages, such as the increased risk of infection due to the need for two surgeries. Degradable synthetic materials with properties similar to bone, such as calcium phosphate cements, are a promising alternative. READ MORE

  4. 4. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Author : Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []

    Abstract : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. READ MORE

    Abstract : The liver is one of the largest organs within the human body and it handles many vital tasks such as nutrient processing, toxin removal, and synthesis of important proteins. The number of people suffering from chronic liver disease is on the rise, likely due to the present ‘western’ lifestyle. READ MORE
