1. 11. Porous structures based on nanopolysaccharides for medical applications

   Författare :Narges Naseri; Nazanin Emami; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

   Sammanfattning : Recently, the use of bio-based nanomaterials has attracted much interest in medical applications due to their cytocompatibility, good moisture stability, good mechanical properties, hydrophilic surfaces and their ability to form porous structures. The aim of this work is to develop porous nanocomposites based on nanochitin and nanocellulose with controlled pore size and porosity in order to facilitate cell growth and interconnectivity and to investigate their potential in wound dressing and cartilage regeneration.

3. 12. Porous materials based on nanopolysaccharides for medical applications: Effect of crosslinking on pore structure and mechanical performance

   Författare :Narges Naseri; Orlando Rojas; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

   Sammanfattning : The objective of this work was to develop nanochitin- and nanocellulose-based crosslinked porous nanostructured materials for wound dressing and cartilage repair with suitable porosity and mechanical properties to facilitate cell growth. In the first part of the work (papers I-III), chitosan-based nanocomposites loaded with a high concentration (50 wt%) of chitin nanocrystals (ChNC) and cellulose nanocrystals (CNC) were prepared via electrospinning for use as wound dressing materials.

4. 13. Perioperative Strategies to Prevent Surgical Site Infection After Shoulder Surgery

   Författare :Vendela Scheer; Anders Kalén; Lena Serrander; Malin Bergman Jungeström; Maria Lerm; Bo Söderquist; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : In Sweden, about 18 000 patients undergo shoulder surgery each year. The current surgical site infection (SSI) rate after planned shoulder surgery is 0,3-5 %, which means that approximately 300 people are affected each year in Sweden. LÄS MER

5. 14. Lower Limb Amputation in Patients with Vascular Disease

   Författare :Anton Johannesson; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rehabilitation outcome; prosthetic; mortality; amputation; Incidence; limb;

   Sammanfattning : The current prevalence of persons amputated at transmetatarsal level or higher in Sweden can be estimated to be between 5000 and 5500 persons (approx. 0.06 % of the population). The majority of these are patients with vascular disease (≈ 80%). LÄS MER

7. 15. Structural and Antibacterial Properties of Silver(I) Compounds with N-donor Ligands: A Challenge for Medical Applications

   Författare :Al-Shimaà A A Massoud; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray diffraction; silver I compounds; solution chemistry; antibacterial activity;

   Sammanfattning : In this thesis, new silver(I) nitrate compounds with N-donor heterocyclic ligands are described. The structures of the obtained crystalline compounds 1-19 were analysed using X-ray single-crystal diffraction. LÄS MER
