The Danish national return-to-work program - aims, content, and design of the process and effect evaluation

The Danish national return-to-work (RTW) program aims to improve the management of municipal sickness benefit in Denmark. A study is currently ongoing to evaluate the RTW program. The purpose of this article is to describe the study protocol. The program includes 21 municipalities encompassing approximately 19 500 working-age adults on long-term sickness absence, regardless of reason for sickness

Spectroscopy of Element 115 Decay Chains

A high-resolution , X-ray and gamma-ray coincidence spectroscopy experiment was conducted at the GSI Helmholtzzentrum für Schwerionenforschung. Thirty correlated alpha-decay chains were detected following the fusion-evaporation reaction 48Ca + 243Am. The observations are consistent with previous assignments of similar decay chains to originate from element Z = 115. For the first time, precise spec

Revealing the size, conformation, and shape of casein micelles and aggregates with asymmetrical flow field-flow fractionation and multiangle light scattering.

Casein (CN) micelles are naturally occurring colloidal protein aggregates present in a dispersed state in milk. In this paper we aim to obtain a detailed description of physicochemical properties of CN micelles over the entire size distribution using asymmetrical flow field-flow fractionation (AsFlFFF) connected to multiangle light scattering (MALS) and refractive index (RI) detection. Conclusions

More on how and why: cause and effect in biology revisited

In 1961, Ernst Mayr published a highly influential article on the nature of causation in biology, in which he distinguished between proximate and ultimate causes. Mayr argued that proximate causes (e.g. physiological factors) and ultimate causes (e.g. natural selection) addressed distinct 'how' and 'why' questions and were not competing alternatives. That distinction retains explanatory value toda

Comorbidities and Mortality in Persons With Schizophrenia: A Swedish National Cohort Study

Objective: Schizophrenia is associated with premature mortality, but the specific causes and pathways are unclear. The authors used outpatient and inpatient data for a national population to examine the association between schizophrenia and mortality and comorbidities. Method: This was a national cohort study of 6,097,834 Swedish adults, including 8,277 with schizophrenia, followed for 7 years (20

Heat transfer and pressure drop in a smooth and ribbed turn region of a two-pass channel

In the present study, the heat transfer and pressure drop in the turn region of a two-pass channel have been investigated experimentally. The liquid crystal thermography method is utilized to measure local heat transfer rates. Eight cases were tested, including one smooth, and seven different rib-roughened turn surfaces. The tested Reynolds numbers are 20,000 and 26,000, respectively. Results indi

Targeted BCL2 inhibition effectively inhibits neuroblastoma tumour growth

Genomic aberrations of key regulators of the apoptotic pathway have hardly been identified in neuroblastoma. We detected high BCL2 mRNA and protein levels in the majority of neuroblastoma tumours by Affymetrix expression profiling and Tissue Micro Array analysis. This BCL2 mRNA expression is strongly elevated compared to normal tissues and other malignancies. Most neuroblastoma cell lines lack thi

Half-Life Systematics across the N=126 Shell Closure: Role of First-Forbidden Transitions in the β Decay of Heavy Neutron-Rich Nuclei.

This Letter reports on a systematic study of β-decay half-lives of neutron-rich nuclei around doubly magic ^{208}Pb. The lifetimes of the 126-neutron shell isotone ^{204}Pt and the neighboring ^{200-202}Ir, ^{203}Pt, ^{204}Au are presented together with other 19 half-lives measured during the "stopped beam" campaign of the rare isotope investigations at GSI collaboration. The results constrain the

Babu wa Loliondo : Healing the Tensions between the Tanzanian Worlds

Tanzanian Ambilikile Mwasapila aka Babu wa Loliondo, a retired Lutheran countryside pastor, suddenly became the most visible media personality and healer in East Africa for half a year in 2011. He had received dreams in which God provided him with the recipe for a herbal medicine that would heal all maladies. Lutheran bishops who had all but abandoned the elderly pastor in his former remote missio

Polymer leaching from film coating: Effects on the coating transport properties.

The release mechanism of metoprolol succinate pellets coated with a blend of a water-insoluble polymer, ethyl cellulose (EC), and a water-soluble polymer, hydroxypropyl cellulose (HPC) is mechanistically explained. The kinetics of drug release and HPC leaching were followed for drug doses. The coating was initially not permeable to the drug, and release started only after a critical amount of the

Defining goals in participatory water management: merging local visions and expert judgements

Management by objectives is intrinsic to the EU Water Framework Directive (WFD) and Swedish environmental policy. We describe three approaches to formulating objectives via model-assisted dialogue with local stakeholders concerning eutrophication in a coastal drainage area in south-eastern Sweden: a WFD eco-centred approach based on 'natural state'; Swedish environmental policy reformulated into q

Enriched housing down-regulates the Toll-like receptor 2 response in the mouse brain after experimental stroke.

Post-ischemic inflammation plays an important role in the evolution of brain injury, recovery and repair after stroke. Housing rodents in an enriched environment provides multisensory stimulation to the brain and enhances functional recovery after experimental stroke, also depressing the release of cytokines and chemokines in the peri-infarct. In order to identify targets for late stroke treatment

Holocene land-cover reconstructions for studies on land cover-climate feedbacks

The major objectives of this paper are: (1) to review the pros and cons of the scenarios of past anthropogenic land cover change (ALCC) developed during the last ten years, (2) to discuss issues related to pollen-based reconstruction of the past land-cover and introduce a new method, REVEALS (Regional Estimates of VEgetation Abundance from Large Sites), to infer long-term records of past land-cove

Searching for a Mobilizing Narrative on Climate Change

Global environmental change is real and everywhere, and so is inequality. Such a warmer, stormier, and divided world will create highly differentiated socioecological impacts and responses to climate change with stronger effects on people, places, and livelihoods that contributed the least. This necessitates mitigation, adaptation, and a solid understanding of their interactions with persistent pr

The assessment of vertical daylight factors across the walls of atrium buildings, Part 1: Square atria

This study investigated the impact of well geometry and surface reflectance on the vertical daylight factors of walls in atria with square plan forms under a CIE standard overcast sky. Artificial sky scale model measurements were used to validate predicted values of vertical daylight factors using the software package Radiance. More simulated vertical daylight factors data for a much wider range o

Exosomes reflect the hypoxic status of glioma cells and mediate hypoxia-dependent activation of vascular cells during tumor development.

Hypoxia, or low oxygen tension, is a major regulator of tumor development and aggressiveness. However, how cancer cells adapt to hypoxia and communicate with their surrounding microenvironment during tumor development remain important questions. Here, we show that secreted vesicles with exosome characteristics mediate hypoxia-dependent intercellular signaling of the highly malignant brain tumor gl

Deletions of 16q in Wilms Tumors Localize to Blastemal-Anaplastic Cells and Are Associated with Reduced Expression of the IRXB Renal Tubulogenesis Gene Cluster.

Wilms tumor is the most common pediatric renal neoplasm, but few molecular prognostic markers have been identified for this tumor. Somatic deletion in the long arm of chromosome 16 (16q) is known to predict a less favorable outcome in Wilms tumor, but the underlying molecular mechanisms are not known. We show that 16q deletions are typically confined to immature anaplastic-blastic tumor elements,

High glucose enhances store-operated calcium entry by upregulating ORAI/STIM via calcineurin-NFAT signalling

ORAI and stromal interaction molecule (STIM) are storeoperated channel molecules that play essential roles in human physiology through a coupling mechanism of internal Ca2+ store to Ca2+ influx. However, the roles of ORAI and STIMin vascular endothelial cells under diabetic conditions remain unknown. Here, we investigated expression and signalling pathways of ORAI and STIM regulated by high glucos
