Streptococcus pyogenes (group A streptococcus) causes a variety of diseases, including acute pharyngitis, impetigo, rheumatic fever and the streptococcal toxic shock syndrome. Moreover, S. pyogenes was responsible for the classical example of a nosocomial infection, the epidemics of puerperal fever (childbed fever) that caused the death of numerous women in earlier centuries. The most extensively

Disturbed haemostasis is a central finding in severe Streptococcus pyogenes infection. In particular, microthrombi are found both at the local site of infection and at distant sites. Platelets are responsible for maintaining vascular function and haemostasis. We report here that M1 protein of S. pyogenes triggers immune-mediated platelet activation and thrombus formation. M1 protein is released fr

A dry release method for fabrication of suspended nanostructures is presented. The technique has been combined with an anti-stiction treatment for fabrication of nanocantilever based nanoelectromechanical systems (NEMS). The process combines a dry release method, using a supporting layer of photoresist which is removed using oxygen ashing in a reactive ion etcher (RIE), with CHF3 plasma induced de

This study demonstrates that a cytotoxic serum reactivity not requiring the presence of complement appears in the sera of patients with acute myelogenous leukemia. The reaction is detected upon short‐term incubation of sera in vitro with autochthonous mononuclear white blood cells from peripheral venous blood of patients at the acute stage of the disease. This reactivity was demonstrated in 18/18

Despite the recent clinical success of T cell checkpoint inhibition targeting the CTLA-4 and PD-1 pathways, many patients either fail to achieve objective responses or they develop resistance to therapy. In some cases, poor responses to checkpoint blockade have been linked to suboptimal CD28 costimulation and the inability to generate and maintain a productive adaptive anti-tumor immune response.

Recently, to reach zero emission levels, some new energy systems based on fuel cells have been developed. This paper presents a review of investigations of these systems by thermodynamics performance, mainly, energy and exergy analysis. With energy analysis, the performance of an energy conversion system cannot be effectively and accurately evaluated. But exergy analysis complements and reinforces

Det är i brottmålsprocesser ovanligt att den anklagades ålder är oklar. Men när den är det så ställs stora krav på tillräckligt precisa metoder eftersom det spelar stor roll vad den anklagade bedöms ha för ålder. De svenska påföljdsbestämmelserna särbehandlar nämligen unga lagöverträdare på olika sätt beroende på ålder. Socialstyrelsen har tagit ställning till frågan huruvida tandmognadsbedömningIn criminal proceedings it is unusual that the age of the accused is unclear. But when it is, it is of utmost importance that the methods used to determine the age are sufficiently precise because the expected age of the accised is of paramount importance. The Swedish penalties provisions specifically deal with juvenile offenders in different ways depending on age. Socialstyrelsen has considered t

The gene for an IgA-binding protein from a group A streptococcal strain was cloned and expressed in Escherichia coli. The IgA-binding protein, called protein Arp, was purified on IgA-Sepharose, allowing complete purification in a single step. Analysis of protein Arp by Western immunoblotting demonstrated a major IgA-binding band, with an apparent molecular weight of 42 kD. The purified protein was

Memories of the transition Memories of the transition is fictive. However, it is knowledge-based speculation. Much of the story is inspired by existing proposals, emerging innovations, or research on the transformations needed to meet our climate targets. We have collected some of these imaginative seeds below so that you can understand and construct your own vision of a post-fossil society. Conte

“Water is life”. During the past decade this phrase has been used repeatedly to emphasize the importance of a number of issues surrounding water services provision including, supply, distribution, governance and political will. This research seeks to investigate the Nairobi City Water and Sewerage Company (NCWSC), a water utility in Kenya, which faces the monumental task of providing water and san

Background: A unique feature of alveolar mast cells is their low high-affinity IgE receptor (FcεRI) expression. Recent discoveries in uncontrolled asthma suggest that the appearance of FcεRI-expressing alveolar mast cells may be a novel disease-specific feature of allergic asthma. This study investigates whether increased FcεRI-expressing alveolar mast cells are present in patients with mild aller

We present an interim archaeological report on the ship- wreck of the Danish-Norwegian flagship Gribshunden. Built in 1485, extensively employed by King Hans as his floating castle, and ultimately lost in June 1495 en route to Kalmar, the ship carried people and material selected to further the political goal of re-unifying the Nordic region. Three field campaigns led by Lund University and Blekin

BACKGROUND: After amputation, the sensorimotor cortex reorganizes, and these alterations might influence motor functions of the remaining extremities.OBJECTIVE: The authors examined how amputation of the dominant or nondominant upper or lower extremity alters deftness in the intact limbs.METHODS: The participants were 32 unilateral upper- or lower-extremity amputees and 6 controls. Upper-extremity
