   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fat-Intrabody Communication; Fat Tissue; Microwave; Propagation; Data Packet Reception; Ex-vivo; Phantom; Communication; Reliability; Implants; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Sammanfattning : In the last two decades, a significant development in the field of medical technology occurred worldwide. This development is characterized by the materialization of various body implants and worn devices, that is devices attached to the body. LÄS MER

3. 22. Aseptic Loosening of Orthopedic Implants : Osteoclastogenesis Regulation and Potential Therapeutics

   Författare :Mehdi Amirhosseini; Anna Fahlgren; Göran Andersson; Teun J. de Vries; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Aseptic loosening is the main cause of failure of orthopedic prostheses. With no pharmaceuticals to prevent or mitigate periprosthetic bone degradation, a surgery to replace the loose implant with a new one is the only choice to restore patients’ function. LÄS MER

4. 23. Strategies in Cochlear Nerve Regeneration, Guidance and Protection : Prospects for Future Cochlear Implants

   Författare :Fredrik Edin; Helge Rask-Andersen; Peetra Magnusson; Maoli Duan; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human vestibular nerve; Scarpa s ganglion; Stem cells; Nanoparticles; Nanocrystalline diamond; Oto-Rhino-Laryngology; Oto-rhino-laryngologi; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Today, it is possible to restore hearing in congenitally deaf children and severely hearing-impaired adults through cochlear implants (CIs). A CI consists of an external sound processor that provides acoustically induced signals to an internal receiver. LÄS MER

5. 24. Improved titanium and steel implants : Studies on bisphosphonate, strontium and surface treatments

   Författare :Paula Linderbäck; Pentti Tengvall; Per Aspenberg; Håkan Engqvist; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : Purpose: The general aim of this thesis was to increase the understanding of biomaterial surface modifications and local delivery of osteoporosis drugs for bone integration. We therefore (i) characterised and investigated model surface coatings for controlled drug delivery in a rat tibia screw model (ii) elucidated the effect of surface treatment for activation of complement system in vitro.

7. 25. On titanium release from dental implants and the inflammatory response

   Författare :Mattias Pettersson; Margareta Molin Thorén; Anders Johansson; Ann Wennerberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; inflammation; dental implants; peri-implantitis; odontologi; Odontology;

   Sammanfattning : In dentistry, dental implants have become a standard treatment for single tooth loss and partial and total edentulism since their introduction by P-I Brånemark in the 1960s. Long-term follow-up studies have shown that dental implantation is a predictable treatment, with an overall implant survival over ninety-five percent. LÄS MER
