Periodontitis is an inflammatory disease of the supporting structures of the teeth and is caused by, among other agents, Porphyromonas gingivalis. P. gingivalis is very resistant to killing by human complement, which is present in a gingival fluid at 70% of the serum concentration. We found that the incubation of human serum with purified cysteine proteases of P. gingivalis (gingipains) or P. ging
Three properdin deficiency phenotypes have been reported--complete deficiency (type I), incomplete deficiency (type II), and dysfunction of properdin protein (type III)--all associated with increased susceptibility to meningococcal disease. Expression of properdin by monocytes was examined in type I deficiency and in two unrelated cases with type II deficiency, one from a Swedish and one from a Da
Background. The incidence of non-Hodgkin lymphoma and prevalence of obesity are increasing globally. A suggested positive association between obesity and risk of non-Hodgkin lymphoma has prompted us to investigate the relationship between body mass index (BMI) and risk of malignant lymphoma subtypes in a population-based case-control study. Methods: Telephone interviews were conducted with 3055 ca
BACKGROUND: The objective of lung transplantation (LTx) is to prolong life, but the survival benefit for patients with severe α(1)-anti-trypsin deficiency (PiZZ) and emphysema is still unclear. The aim of this study was to assess whether PiZZ patients who have undergone lung transplantation (the lung transplant group, TxG) do better than patients who have continued on the usual medical therapy (th
We have determined projected rotational velocities, v sin i, from Magellan/MIKE echelle spectra for a sample of 136 early B-type stars having large Galactocentric distances. The target selection was done independently of their possible membership in clusters, associations or field stars. We subsequently examined the literature and assigned each star as Field, Association, or Cluster. Our v sin i r
Several bacterial species recruit the complement regulators C4b binding protein, Factor H and vitronectin resulting in resistance against the bactericidal activity of human serum. It has recently been demonstrated that bacteria also bind plasminogen, which is converted to plasmin that degrades C3b and C5. In this study, we found that a series of clinical isolates (n=58) of the respiratory pathogen
C1q is the central pattern-recognition molecule in the classical pathway of the complement system and is known to have a key role in the crossroads between adaptive and innate immunity. Hereditary C1q deficiency is a rare genetic condition strongly associated with systemic lupus erythematosus and increased susceptibility to bacterial infections. However, the clinical symptoms may vary. For long, t
In the past decade, many initiatives were taken for the development of antibodies for proteome-wide studies, as well as characterisation and validation of clinically relevant disease biomarkers. Phage display offers many advantages compared to antibody generation by immunisation because it is an unlimited resource of affinity reagents without batch-to-batch variation and is also amendable for high
An increased understanding of cellular uptake mechanisms of macromolecules remains an important challenge in cell biology with implications for viral infection and macromolecular drug delivery. Here, we report a strategy based on antibody-conjugated magnetic nanoparticles for the isolation of endocytic vesicles induced by heparan sulfate proteoglycans (HSPGs), key cell-surface receptors of macromo
Waste in form of fat, oil and grease (FOG) is generated where food is prepared or consumed, e.g. in households. If collected properly, the household FOG could be interesting for biogas production. This fraction has been source-separated and collected separately in a residential area in Malmö, Sweden. The biogas potential has been evaluated by mesophilic digestion experiments. Both single-substrate
The present study was performed in order to get a better understanding of the influence of the scanning angle interval on navigation performance, gestures and strategies in a more realistic outdoor setting. Results indicate that users are able to handle a wide range of angle intervals. We observe different gestures and strategies and provide recommendations for suitable angle intervals. Our observ
This paper presents simultaneous, single shot planar laser-induced fluorescence (PLIF) imaging of four species: OH, CH, CH2O (formaldehyde) and toluene (C6H5CH3) in methane/air jet flames. The jet flames were stabilized by a flat pilot flame generated using a McKenna type burner. Both flames were operated with a stoichiometric premixed methane/air mixture at room temperature and atmospheric pressu
An analysis of high-resolution near-infrared spectra of a sample of 45 asymptotic giant branch (AGB) stars towards the Galactic bulge is presented. The sample consists of two subsamples, a larger one in the inner and intermediate bulge, and a smaller one in the outer bulge. The data are analysed with the help of hydrostatic model atmospheres and spectral synthesis. We derive the radial velocity of
Background Rare cancers are a challenge to clinical practice, and treatment experience, even in major cancer centres to which rare cancers are usually referred, is often limited. We aimed to study the epidemiology of rare cancers in a large population of several countries. Methods We analysed survival by age, sex, subsite, and morphology in 57 144 adults with 14 selected rare cancers diagnosed 198
We used a high-titer recombinant adeno-associated virus (rAAV) vector to express WT or mutant human alpha -synuclein in the substantia nigra of adult marmosets. The alpha -synuclein protein was expressed in 90-95% of all nigral dopamine neurons and distributed by anterograde transport throughout their axonal and dendritic projections. The transduced neurons developed severe neuronal pathology, inc
Allergic rhinitis is a common disease characterized by the symptoms of pruritus, sneezing, hypersecretion and nasal blockage. Increased mucosal barrier permeability has been suggested to be an indicator for the severity of allergic rhinitis. This study investigates the passage of radiolabelled albumin from the nasal mucosal circulation into the lumen in guinea pigs intraperitoneally sensitized and
