1. 1. Gut microflora associated characteristics in children with celiac disease

   Författare :Bo Tjellström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Celiac disease; children; faeces; microflora associated characteristics; short chain fatty acids; branched-chain fatty acids; iso-butyric acid; iso-valeric acid; relatives; faecal microflora; faecal tryptic activity; screening;

   Sammanfattning : Aim: The over-arching aim of this thesis was to study some metabolic functions of the gut microflora in children with known or screening detected celiac disease (CD) and their first-degree relatives. Materials: Study I. A number of 36 untreated CD children, 47 after at least 3 months on glutenfree diet (GFD) and 42 healthy controls (HC). Study II. LÄS MER

3. 2. Acyl-CoA thioesterases : auxiliary enzymes in peroxisomal lipid metabolism

   Författare :Maria A K Westin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Peroxisomes are small organelles essential for life, which carry out a variety of functions mostly related to lipid metabolism, including α- and β-oxidation as well as the first steps of plasmalogen biosynthesis. Peroxisomal β-oxidation metabolizes many different lipids including very long-chain fatty acids, dicarboxylic fatty acids, branched-chain fatty acids, eicosanoids and certain xenobiotic fatty acids.

4. 3. Peroxisomal and mitochondrial enzymes involved in lipid metabolism : studies on function and regulation

   Författare :Veronika Tillander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Fatty acids constitute a major part of the energy that we obtain from the diet and are also the principal source for mammals to store energy. To use the incoming or stored fatty acids as energy, the fatty acids needs to be metabolized of which the majority of fatty acids will be degraded by the mitochondrial β-oxidation system that in the end generates energy to the cell in the form of ATP.

5. 4. Bacterial cytochromes P450-Studies on Cytochrome P450 102A2 and P450 102A3 of Bacillus subtilis

   Författare :Mattias Gustafsson; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; AbrB; Spo0A; monooxygenase; heme; Bacillus subtilis; Cytochrome P450; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Cytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. LÄS MER

7. 5. Characterisation of the Microbial Community in Indoor Environments: a Chemical-Analytical Approach

   Författare :Aleksandra Sebastian; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air; microbial chemical markers; asthma; allergies; tobacco smoke; Infektioner; Infections;

   Sammanfattning : Inhalation of airborne microorganisms and their toxic components and products may induce a wide spectrum of acute and chronic airway manifestations. The study describes important capabilities of chemical marker analysis in defining human exposure to microorganisms in indoor environments. LÄS MER
