För att undersöka mycket snabba förlopp, likt elektroners rörelser kring atomkärnan, krävs ljuspulser som endast är några hundra attosekunder långa. En attosekund ($10^{-18}$ s) är en miljarddels miljarddels sekund, och förhåller sig således ungefär till en sekund som en sekund förhåller sig till två gånger universums ålder. Attosekundspulser, det vill säga ljuspulser kortare än en femtosekund ($

Popular Abstract in Swedish Grupp B streptokocker (GBS; Streptococcus agalactiae) är den vanligaste orsaken till livs-hotande infektioner hos nyfödda barn. Enbart i USA orsakar GBS ~10 000 fall av meningit (hjärnhinneinflammation), pneumoni (lunginflammation) och sepsis (blodförgiftning) varje år. Infektionerna har hög dödlighet och en stor del av de barn som överlever infektionerna får bestående Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity.

On this page you can learn about the management of waste and hazardous waste. Waste must be handled in ways that protect health and the environment, so that recycling is promoted and so the risk of injury does not arise. The Swedish webpage has been updated with the revised waste management handbook. Please visit the Swedish webpage to find the latest information until this page has also been upda

Since the legal reform and adoption of the new sex purchase act in 1999, the efficiency of governmental actions and continuance of social vulnerability among prostitutes/sex workers in Sweden have been recurring topics in public debate. Conflicting views on what the problem actually is and how it might best be dealt with, create a divide between those who advocate a liberal feminist perspective, a

Recent epidemiological data on diseases caused by beta-hemolytic streptococci belonging to Lancefield group C and G ( GCS, GGS) underline that they are an emerging threat to human health. Among various virulence factors expressed by GCS and GGS isolates from human infections, M and M-like proteins are considered important because of their anti-phagocytic activity. In addition, protein G has been i

This study explores the use of manganese ore, iron-carbon particles (Fe-C), and gravel as anode fillers in electroactive constructed wetlands (ECWs) to treat wastewater containing pharmaceuticals and personal care products (PPCPs) including ciprofloxacin (CIP), ofloxacin (OFL), and naproxen (NPX), while also assessing bioelectricity production. Although the presence of PPCPs reduced pollutant remo

Background: Ocrelizumab is a humanized anti-CD20 antibody with increased antibody-dependent cellular cytotoxicity compared with rituximab. This phase I/II study evaluated its safety and efficacy in patients with relapsed/refractory follicular lymphoma (FL) after prior rituximab therapy. Design and methods: Forty-seven patients were treated in three dose cohorts and received eight infusions every 3

Streptococcus pyogenes is one of the most common bacteria infecting humans. One of the factors contributing to the disease-causing properties is the secreted streptococcal cysteine proteinase, SpeB, which degrades several host proteins in connective tissue and circulation. SpeB activity depends on the transformation from an inactive precursor, zymogen, into a mature proteinase. We show that

Streptococcus pyogenes (Group A streptococcus; GAS) is an important human pathogen responsible for mild to severe, life-threatening infections. GAS expresses a wide range of virulence factors, including the M family proteins. The M proteins allow the bacteria to evade parts of the human immune defenses by triggering the formation of a dense coat of plasma proteins surrounding the bacteria, includi

INTRODUCTION: Synaptic dysfunction and loss are pathological hallmarks of neurodegenerative diseases. Neuronal pentraxin 2 (NPTX2), a presynaptic protein involved in synaptic plasticity, has been linked to cognitive decline in Alzheimer's disease (AD) and other neurodegenerative disorders. METHODS: We developed and validated a novel single molecule array (Simoa) for NPTX2 in cerebrospinal fluid, w

Primary hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder associated with autosomal recessive variants in genes required for perforin-mediated lymphocyte cytotoxicity. A rapid diagnosis is crucial for successful treatment. Although defective cytotoxic T lymphocyte (CTL) function causes pathogenesis, quantification of natural killer (NK)–cell exocytosis triggered by K562 targe

Modulenthus is a company in the wood house industry that builds houses in volumes. Volume building means that Modulenthus builds predecorated house volumes in a factory and transports these to the building sites where they are being put together to complete detached houses. The purpose of these Master Thesis is that, on the basis of Modulenthus conditions and wishes, evaluate a possible using of a

BackgroundCellulase enzymes have been reported to contribute with a significant share of the total costs and greenhouse gas emissions of lignocellulosic ethanol production today. A potential future alternative to purchasing enzymes from an off-site manufacturer is to integrate enzyme and ethanol production, using microorganisms and part of the lignocellulosic material as feedstock for enzymes.
