  1. 11. Molecular Studies of Mast Cell Migration and Apoptosis : Two Ways of Regulating Mast Cell Numbers at Sites of Inflammation

    Författare :Jessica Alfredsson; Gunnar Nilsson; Hans-Uwe Simon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; mast cell; SCF; IL-3; FcεRI; migration; apoptosis; Bim; Bcl-2; Bcl-XL; Akt; FOXO; MAPK; Patologi; Pathology; Patologi;

    Sammanfattning : Upon activation mast cells release numerous proinflammatory mediators. With this feature, mast cells play an important role in host defense against pathogens, and are involved in tissue remodeling and wound healing. However, in cases of excessive inflammation the effects of mast cells are detrimental. LÄS MER

  3. 12. Radioactive fall-out from the Chernobyl nuclear power plant accident in 1986 and cancer rates in Sweden, a 25-year follow up

    Författare :Hassan Alinaghizadeh; Robert Wålinder; Marina Taloyan; Gunnar Nilsson; Anders Ahlbom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Sammanfattning : Aim: The current research aimed to study the association between exposure to low-dose radiation fallout after the Chernobyl accident in 1986 and the incidence of cancer in Sweden.Methods: A nationwide study population, selecting information from nine counties out of 21 in Sweden for the period from 1980 – 2010.

  4. 13. Integration and topology of membrane proteins

    Författare :Carolina Boekel; Gunnar von Heijne; IngMarie Nilsson; Stephen High; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; insertion; Sec61; translocation; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Membrane proteins comprise around 20-30% of most proteomes. They play important roles in most biochemical pathways. All receptors and ion channels are membrane proteins, which make them attractive targets for drug design. Membrane proteins insert and fold co-translationally into the endoplasmic reticular membrane of eukaryotic cells. LÄS MER

  5. 14. Low Back Pain : With Special Reference to Prevalence, Diagnosis, Treatment and Prognosis

    Författare :Johan Bogefeldt; Kurt Svärdsudd; Stefan Blomberg; Margaretha Eriksson; Gunnar Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cohort study; time trends; sickness absence; randomised controlled trial; practice patterns; observer variation; Family medicine; Allmänmedicin; Allmänmedicin; Family Medicine;

    Sammanfattning : Objectives. Ascertain if there has been a secular trend in 3-months prevalence of casually reported back pain. Evaluate if such back pain predicts concurrent health as well as future sick leave, disability pension, hospitalization and survival. Study differences in diagnostic assessment and labelling between physicians. LÄS MER

  7. 15. Enzymes and electron transport in microbial chlorate respiration

    Författare :Jan Bohlin; Thomas Nilsson; Lars-Gunnar Franzén; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ideonella dechloratans; c cytochromes; chlorate; chlorate reductase; chlorite dismutase; heterologous expression; heme reconstitution; electron transport; oxidoreductas; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : Microbial chlorate respiration plays an important role in the turnover of oxochlorates in nature and industrial waste management. This thesis deals with the characterization of the molecular components of chlorate respiration in Ideonella dechloratans. LÄS MER
