1. 1. Microscopic colitis : studies of epidemiology, clinical features and nitric oxide

   Författare :Martin Olesen; Robert Löfberg; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Lymphocytic colitis (LC) and collagenous colitis (CC) arc newly recognised inflammatory bowel diseases belonging to the group of microscopic colitides (MC). They are characterised clinically by chronic non-bloody and watery diarrhoea, and a macroscopically normal or near normal colonic mucosa where diagnostic histopathological abnormalities are found.

3. 2. Microscopic colitis

   Författare :Marie-Rose Mellander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Microscopic colitis (MC) is an inflammatory bowel disease (IBD) and a common cause of chronic non-bloody diarrhoea, especially in elderly women. There are two main subtypes, lymphocytic colitis (LC) and collagenous colitis (CC) which are clinically indistinguishable and can be separated only by their characteristic histopathological features.

4. 3. Epidemiological aspects of microscopic colitis

   Författare :Anna Wickbom; Curt Tysk; Johan Bohr; Nils Nyhlin; Bodil Ohlsson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microscopic colitis; epidemiology; risk factors; comorbidity; health-related quality of life;

   Sammanfattning : Microscopic colitis (MC) constitutes the main entities collagenous colitis (CC) and lymphocytic colitis (LC), diseases that are relatively recently described (in 1976 and 1989, respectively).The aims of this thesis were to study the epidemiology of MC, to describe how these diseases affect patients in terms of symptom burden and health-related quality of life (HRQoL), to study potential risk factors such as familial factors, childhood circumstances, educational level, marital status, smoking and comorbidity, and to describe a cohort of patients with ulcerative colitis (UC) or Crohn’s disease (CD) and subsequent MC, and vice versa.

5. 4. Microscopic Characterisation of Solar Cells : An Electron Microscopy Study of Cu(In,Ga)Se2 and Cu2ZnSn(S,Se)4 Solar Cells

   Författare :Jörn Timo Wätjen; Marika Edoff; Angus Rockett; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEM; SEM; FIB; solar cell; CIGS; CZTS; Alternative buffer layers; Gallium gradients; microscopic electrical characterisation; Secondary Phases; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : The sun provides us with a surplus of energy convertible to electricity using solar cells. This thesis focuses on solar cells based on chalcopyrite (CIGSe) as well as kesterite (CZTS(e)) absorber layers. These materials yield record efficiencies of 20.4 % and 11. LÄS MER

7. 5. Dysregulated mucosal immune responses in microscopic colitis patients

   Författare :Sezin Günaltay; Elisabeth Hultgren-Hörnquist; Olof Hultgren; Nils Nyhlin; Allan Mowat; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microscopic colitis; collagenous colitis; lymphocytic colitis; TLR; chemokine; chemokine receptor; IL-37; TCR; Immunologi; Immunology; Biomedicin; Biomedicine;

   Sammanfattning : Microscopic colitis (MC), comprising collagenous colitis (CC) and lymphocytic colitis (LC) is a common cause of chronic watery diarrhea. The diagnosis relies on typical histopathological changes observed upon microscopic examination. LÄS MER
