1. 11. Neural Stem and Progenitor Cells as a Tool for Tissue Regeneration

   Författare :Ulrika Wallenquist; Karin Forsberg Nilsson; Lars Hillered; Karin Holmqvist; Anders Lewén; Johan Bengzon; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; neural stem cells; transplantation; CNS; PNS; progenitor cells; inflammation; CCI; Biochemistry; Biokemi; Neurosurgery; neurokirurgi; Medical Biochemistry; medicinsk biokemi;

   Sammanfattning : Neural stem and progenitor cells (NSPC) can differentiate to neurons and glial cells. NSPC are easily propagated in vitro and are therefore an attractive tool for tissue regeneration. Traumatic brain injury (TBI) is a common cause for death and disabilities. A fundamental problem following TBI is tissue loss. LÄS MER

3. 12. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure

   Författare :Sara Axelsson; Ulrika Nilsson; Kåre Eriksson; Håkan Westberg; Martin Harper; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rosin; resin acids; HPLC ESI-MS; air sampling; urine samples; wood pellets; wood dust; Analytical Chemistry; analytisk kemi;

   Sammanfattning : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. LÄS MER

   Författare :Kimi Drobin; Jochen M. Schwenk; Peter Nilsson; Ulrika Qundos; Angela Silveira; Maria Pernemalm; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; affinity proteomics; immunoassay; antibody microarray; suspension bead array; protein profiling; plasma; serum; biomarker discovery; osteoporosis; inflammatory bowel disease; Crohn s disease; ulcerative colitis; Medical Technology; Medicinsk teknologi;

   Sammanfattning : Affinity-based proteomics utilizes affinity binders to detect target proteins in a large-scale manner. This thesis describes a high-throughput method, which enables the search for biomarker candidates in human plasma and serum. LÄS MER

5. 14. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

   Författare :Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

   Sammanfattning : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. LÄS MER
