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

The nervous system is constantly infiltrated by blood-derived sentinels known as perivascular macrophages. Their immediate precursors have not yet been identified in situ and the mechanism that governs their recruitment is mostly unknown. Here, we provide evidence that CD68 (+)GR(-) monocytes can give rise to perivascular macrophages in mice suffering from endotoxemia. After adhesion to the endoth

Abstract In childhood atopic dermatitis (AD) is the most frequent inflammatory condition. Validated eczema questionnaires have been available for schoolchildren only, but the incidence of atopic dermatitis is highest during infancy. Evidence is needed on the further development of asthma, and rhinitis in these infants with AD and on remission of AD in children. We aimed to validate a parental ques

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

Costa Rica has an important banana-producing industry that requires vast amounts of pesticides. These can leak into the environment and cause health effects. The most widely used pesticide is mancozeb, which is rapidly degraded to the carcinogenic and potentially groundwater-contaminating metabolite ETU. This study was executed in Matina, one of the most densely banana-cultivated areas of Costa Ri

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

The purpose of this study was to gain knowledge about and to understand the difference between the two genders as regards well-being and subjective health among unemployed immigrants, living in Sweden. The central aspect that is studied is, how family and social relations on the one hand, and the relation to the labour market on the other, influence immigrants and how they manage their situation.

The purpose of this work was to present collective data on firefighter fatalities in Sweden between 1937 and 2016. Data presented is directly related to operations only. Fatalities due to long-term exposure of gases, particles, and physical/psychological stress or similar were not included in the study. Also, accidents involving ambulances as well as fatalities in direct relation to physical train

Objectives: The aim was to explore adolescents’ beliefs and awareness regarding fertility and preconception health, as well as their views and experiences of information about fertility and preconception health directed at their age group. Methods: We performed seven semi-structured focus group interviews among upper secondary school students (n = 47) aged 16–18 years in two Swedish counties. Data

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
