Epidemiology of severe Streptococcus pyogenes disease in Europe.

The past two decades have brought worrying increases in severe Streptococcus pyogenes diseases globally. To investigate and compare the epidemiological patterns of these diseases within Europe, data on severe S. pyogenes infections were collected through an EU FP-5 funded programme (Strep-EURO). Prospective population-based surveillance of severe S. pyogenes infection diagnosed during 2003 and 200

Three-Dimensional CFD Modeling of Transport Phenomena in a Cross-Flow Anode-Supported Planar SOFC

In this study, a three-dimensional computational fluid dynamics (CFD) model is developed for an anode-supported planar SOFC from the Chinese Academy of Science Ningbo Institute of Material Technology and Engineering (NIMTE). The simulation results of the developed model are in good agreement with the experimental data obtained under the same conditions. With the simulation results, the distributio

Lungs exposed to 1 hour warm ischemia without heparin before harvesting might be suitable candidates for transplantation.

The limiting factor for lung transplantation is the lack of donor organs. The usage of lungs from donation after cardiac death (DCD) would dramatically increase donor availability. In the present paper we wanted to investigate lungs exposed to 1 h of warm ischemia without heparin followed by flush-perfusion and cold storage compared to lungs harvested from heart beating donors (HBD) using standard

Material Dependence of Water Interactions with Metal Oxide Nanoparticles: TiO2, SiO2, GeO2, and SnO2

Surface interactions of water with nano-TiO2 and structurally related group IV metal dioxide nanoparticles have been investigated using density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations. The investigated clusters include 46 and 92 unit models of TiO2 (i.e., (TiO2)(46) and (TiO2)(92)) of the three low-energy polymorphs of TiO2: anatase, rutile, and brookite. The investiga

Search for a heavy narrow resonance decaying to e mu, e tau, or mu tau with the ATLAS detector in root s=7 TeV pp collisions at the LHC

This Letter presents the results of a search for a heavy particle decaying into an e(+/-)mu(+/-), e(+/-)tau(+/-), or mu(+/-)tau(+/-) final state in pp collisions at root s = 7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb(-1). No significant excess above the Standard Model expectation is observed, and exclusions at 9

Valfrihet – en utmaning för det sociala medborgarskapet

Välfärdstjänsterna har antagit formen av marknadsbaserade tjänster på grund av en ökad marknadsorientering. I artikeln analyseras vad valfrihet gällande välfärdstjänster kan innebära för medborgaren i olika socioekonomiska positioner genom att fokusera faktorer som kan begränsa valmöjligheter. En slutsats är att både resursstarka och resurssvaga har begränsade valmöjligheter. En annan slutsats är

Protein-binding RNA aptamers affect molecular interactions distantly from their binding sites.

Nucleic acid aptamer selection is a powerful strategy for the development of regulatory agents for molecular intervention. Accordingly, aptamers have proven their diligence in the intervention with serine protease activities, which play important roles in physiology and pathophysiology. Nonetheless, there are only a few studies on the molecular basis underlying aptamer-protease interactions and th

In vivo and in vitro effects of flutamide and diethylstilbestrol on fetal testicular steroidogenesis in the rat

Prenatal testosterone surge is considered crucial for physiological masculinization of male progeny. Disorders in sex steroid hormone balance during the fetal development may interfere with male reproductive health later in life. In this study, we have investigated in utero and in vitro effects of flutamide (FLU) and diethylstilbestrol (DES) on fetal rat testicular steroidogenesis. In utero exposu

De oauktoriserade migranterna i svensk byggnadssektor - en studie i deportationspolitik 1990-2004

The unauthorized migration of construction workers to Sweden increased during the 1990s, especially at the end of the decade. The migrants often came from Poland and the Baltic states. The aim of this article is to examine this change of the migration pattern to Sweden and how the Swedish Building Workers Union responded to this new situation. I examine how the Building Workers Union cooperated wi

Vacuum impregnation modulates the metabolic activity of spinach leaves

In this study calorimetric measurements provided evidence of a drastic increase of spinach leaf gross metabolism as a consequence of vacuum impregnation (VI) at a minimum pressure of 150 mbar with trehalose and sucrose isotonic solutions. When applying VI extracellular air is replaced by the impregnation solution, potentially limiting tissue respiration to any remaining air volume in the tissue. H

Acute Mastoiditis in Children – A National Study in Sweden

Popular Abstract in Swedish Bakgrund Man kan fråga sig varför en hel avhandling handlar om något så ovanligt som akut mastoiditit hos barn. Det är den vanligaste komplikationen till öroninflammation men drabbar bara 20-60 barn per år i Sverige. Öroninflammation däremot är en infektion som är så vanlig att nästan alla har haft åtminstone en sådan som barn. I Sverige diagnostiseras upp emot 200 000 One of the greatest threats to society today is the development of bacterial resistance to antibiotics. It is commonly accepted that this is mainly due to the use of antibiotics. Acute otitis media (AOM) is responsible for the highest number of antibiotic prescriptions to children although it is in most cases a self-limiting disease. Nevertheless, complications do occur in some case and the most c

Occurrence of haemosporidian parasites in the paddyfield warbler, Acrocephalus agricola (Passeriformes, Sylviidae)

The blood parasite diversity was studied in paddyfield warblers (Acrocephalus agricola) breeding in NE Bulgaria, SW Russia and S. Kazakhstan. Nine cytochrome b gene lineages were recorded, 4 belonging to Haemoproteus spp. and 5 to Plasmodium spp. The overall prevalence of haemosporidians was 33.3%. The composition of parasites varied geographically, with six lineages recorded in Russia, five linea

Long-term Morbidity and Socioeconomic Outcome among Nordic Childhood Cancer Survivors

Survival after childhood cancer has improved dramatically during the past four decades, resulting in a five-year survival rate of 80% in children recently treated for cancer in the Nordic countries. However, these advances in treatment and survival has come at a price, and many survivors face significant treatment-induced sequelae, most of which only become clinically apparent many years after the

Development of a microfabricated electrochemical-cantilever hybrid platform

The design and fabrication of a combined electrochemical-cantilever microfluidic system is described. A chip integrating cantilevers with electrodes into a microchannel is presented with the accompanying polymer flow cell. Issues such as electrical and fluid connections are addressed, electromechanical behavior in ionic solution is investigated, and two uses of the system are demonstrated. First,

Towards Integrated Pest Management in Red Clover Seed Production

The development of integrated pest management is hampered by lack of information on how insect pest abundances relate to yield losses, and how pests are affected by control measures. In this study, we develop integrated pest management tactics for Apion spp. weevils (Coleoptera: Brentidae) in seed production of red clover, Trifolium pratense L. We tested a method to forecast pest damage, quantifie
