Background. Exposure to lead (Pb) in environmental and occupational settings continues to be a serious public health problem and may pose an elevated risk of genetic damage. Objectives. The aim of this study was to assess the level of oxidative stress and DNA damage in subjects occupationally exposed to lead. Material and methods. We studied a population of 78 male workers exposed to lead in a lea
Current methods for intra-surgical guidance to localize metastases at cancer surgery are based on radioactive tracers that cause logistical challenges. We propose the use of a novel ultrasound-based method, magnetomotive ultrasound (MMUS) imaging that employ a nanoparticle-based contrast agent that also may be used for pre-operative PET/MRI imaging. Since MMUS is radiation free, this eliminates th
OBJECTIVE: To explore the interactions concerning the frail and elderly patients having to do with discharge from acute hospital wards and their participation in medical decision-making. The views of the patients and the medical staff were both investigated.DESIGN: A qualitative observational and interview study using the grounded theory.SETTING AND PARTICIPANTS: The setting was three hospitals in
Background: Staff who plan and organize day center activities may need to observe the attendees’ performance and progression. This led us to develop a tool for that purpose, termed General Occupational Engagement in people with Severe mental illness (GOES). The aim was to investigate its psychometric properties in terms of factor structure, internal consistency, corrected item-total correlations (
The ability of ectotherms to respond to changes in their thermal environment through plastic mechanisms is central to their adaptive capability. However, we still lack knowledge on the physiological and functional responses by which ectotherms acclimate to temperatures during development, and in particular, how physiological stress at extreme temperatures may counteract beneficial acclimation resp
Background: The estrogen receptor (ER) can change expression between primary tumor (PT) and distant metastasis (DM) in breast cancer. A tissue biopsy reflects a momentary state at one location, whereas circulating tumor cells (CTCs) reflect real-time tumor progression. We evaluated ER-status during tumor progression from PT to DM and CTCs, and related the ER-status of CTCs to prognosis. Methods: I
The European Union's Natura 2000 (N2000) is among the largest international networks of protected areas. One of its aims is to secure the status of a predetermined set of (targeted) bird and butterfly species. However, nontarget species may also benefit from N2000. We evaluated how the terrestrial component of this network affects the abundance of nontargeted, more common bird and butterfly specie
PURPOSE: Reliable molecular diagnostic tools are still unavailable for making informed treatment decisions and monitoring the response in patients with castration resistant prostate cancer. We evaluated the significance of whole blood circulating androgen receptor transcripts of full length (AR-FL) and splice variants (AR-V1, AR-V3 and AR-V7) as biomarkers of abiraterone acetate treatment resistan
Viruses are infections species that infect a large spectrum of living systems. Although displaying a wide variety of shapes and sizes, they are all composed of nucleic acid encapsulated into a protein capsid. After virions enter the host cell, they replicate to produce multiple copies of themselves. They then lyse the host, releasing virions to infect new cells. High proliferation rate of viruses
A pre-requisite to reach the EU 2030 and beyond targets is a significantly increased ambition among property owners regarding energy-efficient refurbishments. The Swedish Energy Agency and the National Board of Housing, Building and Planning are on the Swedish government assignment developing a strategy with policy instruments to increase energy-efficiency oriented renovation. In order to design t
Historia i futurum handlar på ett övergripande plan om synen på historieämnet i svensk skola från 1919 till 2011 såsom det kommer till uttryck i styrdokument och lärobokstexter. Den är också en av de första studierna av hur kunskapsutveckling i historia kan uttryckas teoretiskt och hur sådana tankegångar har tillämpats – eller inte tillämpats – på grundskolans och gymnasiets historieämne. I princiFacing an unknown future, the meaning of history is not primarily a fixed set of knowledge about the past, but a well-developed historical consciousness. This is a generic skill, emanating from an understanding of history as something that we are, and at the same time as something that we create. From a historical-cultural perspective, the learning process can be described with a point of departur
Abdominal sepsis is associated with dysfunctional hemostasis. Thrombin generation (TG) is a rate-limiting step in systemic coagulation. Neutrophils can expell neutrophil extracellular traps (NETs) and/or microparticles (MPs) although their role in pathological coagulation remains elusive. Cecal ligation and puncture (CLP)-induced TG in vivo was reflected by a reduced capacity of plasma from septic
Most existing remote sensing-based evapotranspiration (ET) algorithms rely exclusively on polar-orbiting satellites with thermal infrared sensors, and therefore the resulting ET values represent only "instantaneous or snapshot" values. However, daily ET is more meaningful and useful in applications. In this study, daily ET estimates are obtained by combining data from the MODIS sensor aboard the p
The mitochondrial protein frataxin plays a central role in mitochondrial iron homeostasis, and frataxin deficiency is responsible for Friedreich ataxia, a neurodegenerative and cardiac disease that affects 1 in 40000 children. Here we present a single-particle reconstruction from cryoelectron microscopic images of iron-loaded 24-subunit oligomeric frataxin particles at 13 and 17 angstrom resolutio
Recent climate warming has altered plant phenology at northern European latitudes, but conclusions regarding the spatial patterns of phenological change and relationships with climate are still challenging as quantitative estimates are strongly diverging. To generate consistent estimates of broad-scale spatially continuous spring plant phenology at northern European latitudes (> 50° N) from 2000
Alloimmunization against the RhD antigen is the most common cause of hemolytic disease of the fetus and newborn. Antenatal anti-D prophylaxis in addition to postnatal anti-D prophylaxis reduces the number of RhD-immunizations compared to only postnatal administration. Cell-free fetal DNA released from the apoptotic trophoblastic placental cells into the maternal circulation can be used to determin
With the increased availability of computational resources, the past decade has seen a rise in the use of computational fluid dynamics (CFD) for medical applications. There has been an increase in the application of CFD to attempt to predict the rupture of intracranial aneurysms, however, while many hemodynamic parameters can be obtained from these computations, to date, no consistent methodology
PURPOSE: Three major glaucoma trials, all using the same Humphrey visual field tests, specified different criteria to define visual field progression. This article compares the performance of these criteria with a reference standard of unanimous classifications by 3 independent glaucoma experts. DESIGN: Longitudinal, comparative study of diagnostic criteria. PARTICIPANTS AND CONTROLS: Two hundred
Characterization of directed differentiation of pluripotent stem cells towards therapeutically relevant cell types, including pancreatic beta-cells and hepatocytes, depends on molecular markers and assays that resolve the signature of individual cells. Pancreas and liver both have a common origin of anterior definitive endoderm (DE). Here, we differentiated human embryonic stem cells towards DE us
