Goodpasture disease (GP) is defined by the presence of anti-glomerular basement membrane (anti-GBM) antibodies and rapidly progressive glomerulonephritis. Besides anti-GBM, many patients with GP produce anti-neutrophil cytoplasmic antibodies (ANCA). For elucidation of the pathophysiologic significance of ANCA in this setting, epitope and antigen specificity of the anti-GBM antibodies and antigen s

Popular Abstract in Swedish För att vi människor ska kunna upprätthålla balansen och utföra rörelser behöver vi ett komplext styrsystem som kontinuerligt kontrollerar och samordnar kroppens rörelser. Detta styrsystem, som kallas postural kontroll, får sin information från synen, balanssinnet (vestibularisorganen), led-muskelsinnet (proprioception) och receptorer i huden (mekanoreceptorer). Om någoThe ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. This emphasizes the importance of rapid and accurate adaptation processes that can optimize

PURPOSE: A previous study has shown age- and sex-related differences in abdominal aortic compliance. In that study blood pressure determined by auscultation in the brachial artery was assumed to be equal to blood pressure in the abdominal aorta. To validate our findings we investigated the pressure-diameter (P-D) relationship of the abdominal aorta. METHODS: Diameter and pulsatile diameter change

A flow injection cell-based biosensor was constructed for 2,4-dichlorophenol (DCP) analysis by using a Clark-type oxygen electrode as a transducer. A mixed bacterial culture capable to biodegrade DCP was immobilized between a Teflon membrane and a dialysis membrane and attached to the oxygen electrode. Optimization of the flow rate, the injection volume, the carrier buffer concentration, and pH wa

The possible risks of radio-frequency electromagnetic fields for the human body is a growing concern for our society. We have previously shown that weak pulsed microwaves give rise to a significant leakage of albumin through the blood-brain barrier. In this study we investigated whether a pathologic leakage across the blood-brain barrier might be combined with damage to the neurons. Three groups e

In humans, beta-alanine (BAL) and the neurotransmitter gamma-aminobutyrate (GABA) are transaminated by a single aminotransferase enzyme. Apparently, yeast originally also had a single enzyme, but the corresponding gene was duplicated in the Saccharomyces kluyveri lineage. SkUGA1 encodes a homologue of Saccharomyces cerevisiae GABA aminotransferase, and SkPYD4 encodes an enzyme involved in both BAL

Popular Abstract in Swedish Denna avhandling utvecklar nya tekniker för analys av kointegrationssamband i paneldata. Det första kapitlet är en introduktion medan de resterande sex innehåller avhandlingens huvudsakliga bidrag. Det andra kapitlet behandlar estimering av kointegrationssamband när regressorerna är endogena, vilket medför att minsta kvadratmetoden inte längre är väntevärdesriktig om dThis thesis develops new techniques for analyzing cointegrated relationships in panel data. The first chapter is introductory while the remaining six contain the main contributions. The second chapter is concerned with the estimation of a cointegrated panel relation with endogenous regressors, in which case the least squares estimator is biased unless it is conditioned on the lags and leads of th

Background and Purpose-Elevated levels of endothelin 1 (ET 1) have been reported in cerebral ischemia A role for ET may prove more important if the vascular receptors were changed We addressed whether there is any change in ET receptor expression in cerebral ischemia Methods-The right middle cerebral artery (MCA) was occluded in male Wistar rats for 2 hours with the intraluminal filament method Th

Biofiltration of hydrophobic volatile pollutants is intrinsically limited by poor transfer of the pollutants from the gaseous to the liquid biotic phase, where biodegradation occurs. This study was conducted to evaluate the potential of silicone oil for enhancing the transport and subsequent biodegradation of hexane by the fungus Fusarium solani in various bioreactor configurations. Silicone oil w

We study the large-time dynamics of a Markov process whose states are finite directed graphs. The number of the vertices is described by a supercritical branching process, and the edges follow a certain mean-field dynamics determined by the rates of appending and deleting. We find sufficient conditions under which asymptotically a.s. the order of the largest component is proportional to the order

Utsikter - föreläsnngar från Helgonabacken ("Views - Lectures from Helgonabacken" consists of public lectures by teachers at the Department for Comparative Literature, Lund university. Most of the lectures deal with contemporary Swedish literature, but there are also texts on Italian and Danish poetry and American cinema.
