1. 11. Central and peripheral adaptation after nerve repair with a synthetic biocompatible adhesive

   Författare :Thomas Landegren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The epineural repair technique is currently the accepted standard for peripheral nerve repair. However, due to the demanding nature of this method, it is not uncommon to delay or even omit action, especially in situations which are associated with extensive traumatic injuries. LÄS MER

3. 12. A tailored biocompatible neural interface for long term monitoring in neural networks

   Författare :Per Köhler; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

   Sammanfattning : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. LÄS MER

   Sammanfattning : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.

5. 14. Investigation of nanoparticle-cell interactions for development of next generation of biocompatible MRI contrast agents

   Författare :Natalia Abrikossova; Kajsa Uvdal; Caroline Brommesson; Eva Särndahl; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Progress in synthesis technologies and advances in fundamental understanding of materials with low dimensionality has led to the birth of a new scientific field, nanoscience, and to strong expectations of multiple applications of nanomaterials. The physical properties of small particles are unique, bridging the gap between atoms and molecules, on one side, and bulk materials on the other side. LÄS MER

7. 15. Enzyme Immunoassay in Combination with Liquid Chromatography for Sensitive and Selective Determination of Drugs in Biosamples

   Författare :Ulf Lövgren; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; amplification; alkaline phosphatase; enzyme immunoassay; liquid chromatography; flow-injection; micellar; Analytisk kemi;

   Sammanfattning : Two different sensitive microtitre-plate based enzyme immunoassays were developed and evaluated for determination of the model drug compound, budesonide, in blood plasma. In the first approach, high sensitivity was obtained by using amperometric detection in a flow injection system for determination of the enzyme product p-aminophenol. LÄS MER
