Group B Streptococcus (GBS) is a leading cause of invasive bacterial infections in human newborns. A key GBS virulence factor is its capsular polysaccharide (CPS), displaying terminal sialic acid (Sia) residues which block deposition and activation of complement on the bacterial surface. We recently demonstrated that GBS Sia can bind human CD33-related Sia-recognizing immunoglobulin (Ig) superfami

Lymphocytes from human peripheral blood were separated by Countercurrent distribution (CCD) in a charged aqueous two-phase system composed of Dextran T 500 and polyethylene glycol 6000. Maximal responses to the T-cell mitogens phytohemagglutinin and concanavalin A were detected in a part of the distribution corresponding to the area where the highest percentage of E rosetting cells were seen. Anti

Regular prophylactic treatment with factor VIII (FVIII) and factor IX (FIX) concentrates in hemophilia A and B, respectively, is introduced in early infancy and has resulted in dramatic improvement of the conditions. Recombinant FVIII and FIX concentrates have been available for > 25 years and have been modified and refined through the years; however, unfortunately frequent intravenous administrat

EndoS from Streptococcus pyogenes efficiently hydrolyzes the functionally important and conserved N-linked glycan of IgG in human blood. Repeated i.v. administration of EndoS in rabbits completely hydrolyzes the glycans of the whole IgG pool, despite the generation of anti-EndoS antibodies. EndoS administration had no apparent effects on the health of the animals. EndoS hydrolysis of the IgG glyca

We have characterized 2 distinct mechanisms through which infectious agents may promote platelet adhesion and thrombus formation in flowing blood, thus contributing to the progression of disease. In one case, the process initiates when the integrin alpha(IIb)beta(3) mediates platelet arrest onto immobilized bacterial constituents that have bound plasma fibrinogen. If blood contains antibodies agai

Protein ADP-ribosylation is a reversible post-translational modification that regulates important cellular functions. The identification of modified proteins has proven challenging and has mainly been achieved via enrichment methodologies. Random mutagenesis was used here to develop an engineered Af1521 ADP-ribose binding macro domain protein with 1000-fold increased affinity towards ADP-ribose. T

Vi kryllar av bakterier. De bor framför allt i vår tjocktarm där de lever på de delar av vår mat som vi inte kan ta hand om själva. I utbyte omvandlar bakterierna en del av maten de äter till vitaminer och fettsyror som är viktiga för oss. Det bor flera olika arter av bakterier i vår tarm som äter lite olika saker, eftersom det är ont om mat för så många har de flesta specialiserat sig för att minHuman 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). A PUL from the human gut bacterium Bacteroides ovatus was

The airflow field around air-intake related geometries has been investigated experimentally and numerically. The configuration of the experimental set-up is used to model a jet engine running near the ground. The experiments have been carried out using both PIV and LDA techniques in order to obtain the mean and fluctuating velocity field as well as the low speed frequencies related to the system o

The compositions of alternative jet fuels can vary radically, and the consequences of these differences are a subject of ongoing investigation. Numerical combustion simulations are vital to this research and require chemical reaction mechanisms that efficiently and accurately capture the chemical pathways of combustion. Here, we present the recently developed Z79 collection of small pathway-centri

The comparative and combined effects of nitric oxide (NO) and higher alkanes on methane oxidation were examined by experimentation and kinetic modeling. Experiments were conducted using fuel-lean, lower-alkanes mixtures with NO (0-400 ppm v/v) in an atmospheric flow reactor at residence time of 2 s over the temperature range of 820-950 K. NO was found to greatly promote methane conversion, and its

We have conducted a phenomenological study on students who will become officers (KB-elever) and our subject is leadership. Our first purpose was to determine their point of view in leadership and how the describe it on two occasions. One occasion before and one after a field-training course in survival techniques. We also wanted to see if the view on leadership was shared and if it had changed aft
