This extended study has evaluated the incidence for similar to 40% of the Swedish population of 9 million inhabitants. Sweden is considered to be iodine sufficient country. Methods:All patients including children, who were newly diagnosed with overt hyperthyroidism in the

Mitochondrial permeability transition following calcium overload. - Its role in neuronal cell death and potential as a pharmacological target.

Popular Abstract in Swedish Hjärnan är ett energikrävande organ och förbrukar ca 20% av blodets syre trots att den bara utgör 1-2% av kroppsvikten. Mitokondrien är den del av cellen där syre och näringsämnen förbränns till koldioxid och vatten, och mitokondrien kallas ofta för cellens kraftstation. Denna process, den så kallade cellandningen, är kopplad till produktion av den energirika molekylen There is currently no clinically available drug with neuroprotective properties to limit the evolving cell death following e.g. stroke or traumatic brain injury. The mitochondrial permeability transition (mPT) is a potential pathological mechanism causing cell death in the CNS. As the name implies, the mPT is defined by a sudden increase in permeability of the inner mitochondrial membrane, whose n

Immune function in a free-living bird varies over the annual cycle, but seasonal patterns differ between years

A central hypothesis of eco-immunology proposes trade-offs between immune defences and competing physiological and behavioural processes, leading to immunological variation within and among annual-cycle stages, as has been revealed for some species. However, few studies have simultaneously investigated patterns of multiple immune indices over the entire annual cycle in free-living birds, and none

Boron carbide coatings for neutron detection probed by x-rays, ions, and neutrons to determine thin film quality

Due to the present shortage of He-3 and the associated tremendous increase of its price, the supply of large neutron detection systems with He-3 becomes unaffordable. Alternative neutron detection concepts, therefore, have been invented based on solid B-10 converters. These concepts require development in thin film deposition technique regarding high adhesion, thickness uniformity and chemical pur

Overview of the synoptic and pollution situation over Europe during the EUCAARI-LONGREX field campaign

In May 2008 the EUCAARI-LONGREX aircraft field campaign was conducted within the EUCAARI intensive observational period. The campaign aimed at studying the distribution and evolution of air mass properties on a continental scale. Airborne aerosol and trace gas measurements were performed aboard the German DLR Falcon 20 and the British FAAM B.4e-146 aircraft. This paper outlines the meteorological

Implantable cardioverter defibrillator use in arrhythmogenic right ventricular cardiomyopathy in North America and Europe

Background and Aims: Implantable cardioverter-defibrillators (ICDs) are critical for preventing sudden cardiac death (SCD) in arrhythmogenic right ventricular cardiomyopathy (ARVC). This study aims to identify cross-continental differences in utilization of primary prevention ICDs and survival free from sustained ventricular arrhythmia (VA) in ARVC. Methods: This was a retrospective analysis of AR

The course of plasma alpha-1-microglobulin and haemolysis during cardiac surgery and the relationship to acute kidney injury, a pilot study

Haemolysis occurring during cardiac surgery with cardiopulmonary bypass (CPB) is assumed to be a risk factor for postoperative acute kidney injury (AKI). Plasma alpha-1 microglobulin (A1M) may have a protective role as haem scavenger. The aim of this study was to evaluate the association between AKI and the degree of haemolysis and the course of A1M concentrations during cardiac surgery, respectiv

Proton exchange membranes with perfluorobenzenesulfonic acid groups for vanadium redox flow battery applications

Proton exchange membranes (PEMs) are critical to the performance of vanadium redox flow batteries (VRFBs). Still, conventional perfluorosulfonic acid membranes such as Nafion® suffer from poor ion selectivity and limited long-term stability. In this study, we introduce PEMs prepared from four types of poly(arylene perfluorobenzenesulfonic acid)s, synthesized via polyhydroxyalkylations of biphenyl

Extravascular incidental findings in computed tomography angiography are associated with lower amputation-free survival in patients with acute lower limb ischaemia

BACKGROUND: Emergency computed tomography angiography (CTA) is the most important imaging modality to visualize arterial occlusions in patients with acute lower limb ischaemia (ALI). Extravascular incidental findings (EVIFs) have received less attention.PURPOSE: The aims of this study were to evaluate the incidence of EVIFs of immediate clinical relevance in patients with ALI undergoing CTA and ev

On the use of prostate-specific antigen for screening of prostate cancer in European Randomised Study for Screening of Prostate Cancer

Prostate-specific antigen (PSA) has been the main drive for early detection of prostate cancer (PCa), including in population-based screening as in the European Randomised Study for Screening of Prostate Cancer (ERSPC). The specificity of PSA to indicate men with biopsy detectable prostate cancer can be improved by adding information obtained by new biomarkers, such as PSA isoforms. This improveme
