1. 1. The digestive machinery of a human gut bacterium : Structural enzymology of galactomannan utilisation

   Författare :Viktoria Bågenholm; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Glycoside hydrolase; enzymology; structural biology; kinetics; HPLC; product profiles; structure-function;

   Sammanfattning : Human gut bacteria utilise different types of polysaccharides present in our diet. One of these polysaccharides is galactomannan. Many organisms in the phylum Bacteroidetes have gene clusters encoding for all proteins required for hydrolysis, binding and transport of one type of polysaccharide, called polysaccharide utilisation loci (PULs).

3. 2. Extended-Spectrum Beta-Lactamase-Producing Enterobacteriaceae: Epidemiology, Risk Factors, and Duration of Carriage

   Författare :Johan Tham; Enheten för infektionssjukdomar; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extended-spectrum beta-lactamase; ESBL; risk factors; resistant bacteria; E. coli; Enterobacteriaceae; antibiotics; food;

   Sammanfattning : In human medicine, the most important family of bacteria is Enterobacteriaceae, which includes genera and species that cause well-defined diseases and also nosocomial infections. These bacteria can give rise to numerous infections such as septicaemia and urinary tract infections. LÄS MER

4. 3. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

   Författare :Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

   Sammanfattning : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. LÄS MER

5. 4. Discovery of Novel Receptors for Lipid Mediators - a study leading to the identification of receptors involved in metabolism and the immune system

   Författare :Niclas Nilsson; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; Clinical biology; Thiazolidinedione; SCFA; FFA; FFA2R; FFA1R; GPR43; GPR41; GPR40; BLT2; GPCR; Orphan; Receptor;

   Sammanfattning : Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. LÄS MER

7. 5. Endothelial Barrier Dysfunction in Multiple Organ Injury. An Experimental Study in Rats

   Författare :Xiaoming Deng; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Endothelial barrier permeability; Multiple organ dysfunction syndrome; Zymosan; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : Multiple organ dysfunction syndrome (MODS) is still the leading cause of mortality in the surgical intensive care unit. The effect on among others endothelial barrier permeability, reticuloendothelial function, organ function and protease-antiprotease activities was studied following a variety of challenges, especially over-activation of macrophages induced by intraperitoneal administration of zymosan.
