The use of pesticides has increased during the past decades, also increasing the risk of exposure to toxic pesticides that can cause detrimental health effects in the future. This is of special concern among farmers in low-to-middle-income countries that may lack proper training in the safe use of these chemicals. To assess the situation in Bolivia a cross-sectional study in three agricultural com

Hydrides GdGaHx were obtained by exposing the Zintl phase GdGa with the CrB structure to a hydrogen atmosphere at pressures from 1.5 to 50 bar and temperatures from 50 to 500 °C. Structural analysis by powder X-ray diffraction suggests that conditions with hydrogen pressures in a range between 15 and 50 bar and temperatures below 500 °C afford a uniform hydride phase with the NdGaH1.66 structure (

The tensile response under displacement controlled loading of nano-sized single crystal Cu beams, solid or holding square shaped through-the thickness voids, have been investigated through 3D molecular dynamics simulations using free-ware LAMMPS [1]. For the same beam size and void height, the void width along the beam length axis was varied. Two different crystallographic orientations were consid

The harm that pathogens cause to hosts during infection, termed virulence, varies across species from negligible to a high likelihood of rapid death. Classic theory for the evolution of virulence is based on a trade-off between pathogen growth, transmission and host survival, which predicts that higher within-host growth causes increased transmission and higher virulence. However, using data from

31P magnetic resonance spectroscopy (MRS) offers a unique non-invasive window on energy metabolism in skeletal muscle, with possibilities for longitudinal studies and of obtaining important bioenergetic data continuously and with sufficient time resolution during muscle exercise. The present paper provides an introductory overview of the current status of in vivo 31P MRS of skeletal muscle, focusi

This article reports on in situ macroscopic scale imaging of NiO-YSZ (YSZ is yttria-stabilized zirconia) reduction under applied stress - a phase transition taking place in solid oxide electrochemical cells in a reducing atmosphere of a hydrogen/nitrogen mixture and at operation temperatures of up to 1073K. This process is critical for the performance and lifetime of the cells. Energy-resolved neu

The activation of the complement system is a key initiating step in the protective innate immune-inflammatory response against injury, although it may also cause harm if left unchecked. The structurally related soluble complement inhibitors C4b-binding protein (C4BP) and factor H (FH) exert a tight regulation of the classical/lectin and alternative pathways of complement activation, respectively,

Background: Pediatric anxiety disorders are highly prevalent and associated with significant functional disabilities and lifelong morbidity. Cognitive-behavioral therapy (CBT), sertraline, and their combination are effective treatments, but little is known about how these treatments exert their effects.Methods: Using network intervention analysis (NIA), we analyzed data from the largest randomized

Occupational safety and health (OSH) is a vital part of the right to health. While the International Labor Organization (ILO) historically treated OSH as an entirely technical matter, it has increasingly been influenced by a human rights agenda. The ILO has responded by adopting and promoting a large number of international standards-in the form of conventions, recommendations, and codes of practi

Background: While higher rates and earlier onset of frailty have been reported among adults with intellectual and developmental disabilities (IDD), research on how best to support these individuals is lacking. Method: An international consultation relied on three consensus building methods: the Nominal Group Technique, an NIH consensus conference approach, and a Delphi survey. Results: There is ag

The quinoline-3-carboxamides (Q compounds) are a family of small molecules with immunomodulatory functions that have shown efficacy in various murine models of inflammatory diseases. One such compound has demonstrated antitumor effects in murine models. Q compounds bind to S100A9, thereby preventing its ligation to TLR4 and RAGE. S100A9 is a small molecule which has shown to have a role in the est

Preliminary mobile was considered to be a device to make human connections easier. But today the consumption of this device has been evolved to a platform for gaming, web surfing and GPS-enabled application capabilities. Embedding GPS in handheld devices, altered them to significant trajectory data gathering facilities. Raw GPS trajectory data is a series of points which contains hidden informatio

Chemokines constitute a large family of low-molecular-weight proteins (∼10 kDa in size), recognized primarily for their role in directing leukocyte migration under both homeostatic and inflammatory settings. The chemokine CCL25 displays a unique and highly restricted expression pattern compared with other chemokine family members. In the steady state, CCL25 is expressed at high levels primarily in

With an ageing population and a discourse of active ageing guiding welfare policies, initiatives to engage older people in health promoting activities have been established. One growing phenomenon is Senior Summer Camps, arranged all over Sweden in beautiful natural environments close to water. Their main purpose is to enable older people to participate in outdoor activities in an institutionalize

AbstractShiga toxin (Stx) is the main virulence factor of enterohemorrhagic Escherichia coli (EHEC). EHEC strains cause gastrointestinal infection and release Stx that can gain access to the circulation. Patients may develop hemolytic uremic syndrome with extensive kidney damage. In the first paper we investigated if blood cell-derived microvesicles released during EHEC infection contain Stx. Toxi

We present a clinical distance measure for Pareto front evaluation studies in radiotherapy, which we show strongly correlates (r = 0.74 and 0.90) with clinical plan quality evaluation. For five prostate cases, sub-optimal treatment plans located at a clinical distance value of >0.32 (0.28–0.35) from fronts of Pareto optimal plans, were assessed to be of lower plan quality by our (12) observers (p

The physical housing environment is important to facilitate activities of daily living (ADL) for older people. A hindering environment may lead to ADL dependence and thus increase the need for home services, which is individually restricting and a growing societal burden. This study presents simulations of policy changes with regard to housing accessibility that estimates the potential impact spec
