  1. 1. Near infrared and skin impedance spectroscopic in vivo measurements on human skin : development of a diagnostic tool for skin cancer

    Författare :Ida Bodén; Peter Naredi; Britta Lindholm-Sethson; Paul Geladi; Bo Karlberg; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Combined probe head; Malignant melanoma; diagnosis; NIR; Skin impedance; PCA; PLS-DA; kirurgi; Surgery;

    Sammanfattning : Every year approximately 2800 Swedes are diagnosed with malignant melanoma, the form of cancer that is most rapidly increasing in incidence in the Western world. The earlier we can identify and diagnose a malignant melanoma, the better is the prognosis. LÄS MER

  2. 2. Methodological aspects of unspecific building related symptoms research

    Författare :Bo Glas; Berndt Stenberg; Anna-Lena Sunesson; Erik Zimerson; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sick building syndrome; SBS; exposure measurement; GC-MS; questionnaire; symptom; variability; PCA; PLS-DA; Occupational medicine; Yrkesmedicin;

    Sammanfattning : This thesis deals with methological issues in the study of chemical exposure and sick building syndrome (SBS). SBS is a combination of general, mucosal and skin symptoms that some people experience when staying in specific buildings. The aim was to find chemical patterns associated with SBS, but also to address methological problems in such study. LÄS MER

  3. 3. The advantages of being small : Glycosyltransferases in many dimensions and glycolipid synthesis in Mycoplasma Pneumoniae

    Författare :Maria Rosén Klement; Åke Wieslander; Christelle Breton; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Glycosyltransferase; lipid; membrane; glycolipid; ACC; PLS-DA; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : The synthesis and breakdown of sugars is one of the most important functions in Nature. Consequently, sugar structures are used both as energy storage and as building blocks to stabilise and protect the cell. The formation of these structures is performed by glycosyltransferases (GT), an enzyme group structurally conserved within all kingdoms. LÄS MER

  4. 4. A multivariate approach to the interpretation of patterns in homicidal and suicidal sharp force fatalities

    Sammanfattning : A multivariate approach to the interpretation of patterns in homicidal and suicidal sharp force fatalities By Thore Karlsson, Karolinska Institute, Institution of Oncology Pathology, Department of Forensic Medicine. Sharp force injury is in Sweden as in many other European countries the leading cause of homicidal deaths. LÄS MER

  5. 5. Epidemiology and Statistical Modeling in Burn Injuries

    Författare :Homayoun Sadeghi Bazargani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Burn injuries;

    Sammanfattning : An important issue in assessing the epidemiology of injuries, including burns, is the investigation of appropriate methodologies and statistical modeling techniques to study injuries in an efficient and trustworthy manner. The overall aim of this thesis is to analyze epidemiological patterns and assess the appropriateness of supervised statistical models to investigate burn risks and patterns. LÄS MER
