    Author : Hector Martinez Avila; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nasoseptal Chondrocytes; Tissue Engineering; Auricular Cartilage; Auricular reconstruction; Bacterial Nanocellulose; Neocartilage; Nanofibrillated Cellulose; Mononuclear Cells; 3D Bioprinting;

    Abstract : In about 2:10,000 births the external part of the ear, the auricle, is severely malformed or absent. Furthermore, tumors and trauma can cause defects to the auricle. READ MORE

  4. 2. Biodegradable Thermoplastic Elastomers

    Author : Basse Asplund; Jöns Hilborn; Tim Bowden; Iskender Yilgör; Uppsala universitet; []
    Keywords : Chemistry; poly urethane ; poly urethane urea ; biomaterial; biodegradable; polymer; thermoplastic elastomer; haemocomatible; tissue engineering; biocompatible; Kemi;

    Abstract : A novel strategy for synthesising segmented poly(urethane urea) (PUU) without using a chain extender but nevertheless with the opportunity to vary the hard segment content has been developed. The strategy is based on amine formation from isocyanate upon reaction with water. READ MORE

  5. 3. Glass Ionomer Cements with Improved Bioactive and Antibacterial Properties

    Author : Song Chen; Håkan Engqvist; Wei Xia; Jie Zhou; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterial; glass ionomer cement; bioactivity; hydroxyapatite; monetite; calcium silicate;

    Abstract : Dental restorative cements are placed in a harsh oral environment where they are subjected to thermal shock, chemical degradation, and repeating masticatory force. The ideal restorative dental cements should have superior mechanical properties, chemical stability, aesthetic, good handling properties, biocompatibility, antibacterial properties, and preferably bioactivity.

  6. 4. Interactions between whole blood and biomaterial surfaces. With focus on the respiratory burst of adhering neutrophils as an early sign of cytotoxicity

    Author : Noushin Yahyapour; Göteborgs universitet; []
    Keywords : wettability; titanium; glass; peritoneal dialysis fluid; surface-adhering neutrophils; respiratory burst; thrombin; kallikrein; complement C5b-9;

    Abstract : Although a vast array of materials is used to augment or replace a natural function in the human body, many of them cause side-effects or may be rejected. The growing need for more biocompatible devices has been accompanied by an increase in new materials. READ MORE

  7. 5. On the pathogenesis of infections associated with percutaneous osseointegrated orthopaedic implants

    Author : Magdalena Zaborowska; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osseointegration; amputation prosthesis; implant-associated infection; biofilm; staphylococci; extracellular vesicles; host defence; cytokines; cell death;

    Abstract : Orthopaedic implants enable the restitution of locomotor function and improve the quality of life of many people. However, biomaterial-associated infection may occur due to the propensity of microorganisms to adhere and colonize implant surfaces. READ MORE
