Background: Very preterm infants are at high risk of developing chronic lung disease, which requires respiratory support and might have long-term sequelae. As lung inflammation plays an important role in pathogenesis, antileukotrienes have been explored in both clinical and animal studies. We aimed to assess the benefits and harms of antileukotrienes for the prevention and treatment of respiratory

Active pre-chamber configurations are considered a valuable solution for improving the operation of the internal combustion engine, in the view to overcome the many challenges it has been made to face. Combining this technology with the use of natural gas, a fuel that has increasing availability and interest in the market share, it is possible to burn ultra-lean mixtures (with air-to-fuel ratios,

The European eel population is critically endangered due to a multitude of human-induced factors such as habitat fragmentation, parasites, fishing, and climate change. In freshwater, downstream migrating silver eels encountering hydroelectric plants often suffer substantial delays and increased mortality from trash-rack impingement and turbine-induced mortality. Downstream passage problems can be

Particulate radioactivity, a characteristic of particulate matter, is primarily determined by the abundance of radionuclides that are bound to airborne particulates. Exposure to high levels of particulate radioactivity has been associated with negative health outcomes. However, there are currently no spatially and temporally resolved particulate radioactivity data for exposure assessment purposes.

Background: Despite a far from perfect correlation with middle ear growth, nasopharyngeal cultures are sometimes used in children with acute otitis media (AOM) in order to have some idea of the causative pathogen. How these cultures are used in clinical practice and to what extent they influence clinical management has not previously been studied. The objective with this study was to investigate i

Numerical modeling is an efficient tool for experimental validation and for gaining a deeper understanding of complex material phenomena, especially when causal relationships are overlaid by material variability. Wood is such a highly orthotropic and complex material, which in engineering problems however is considered as macro-homogeneous. The aim of this study is to numerically investigate stres

The glymphatic system is a waste clearance system in the brain that relies on the flow of cerebrospinal fluid (CSF) in astrocyte-bound perivascular spaces and has been implicated in the clearance of neurotoxic peptides such as amyloid-beta. Impaired glymphatic function exacerbates disease pathology in animal models of neurodegenerative diseases, such as Alzheimer's, which highlights the importance

The article begins with a presentation of the role of demonstration and pantomime in the evolution of teaching building on Gärdenfors and Högberg (2017). In comparison to different forms of animal communication, demonstration is voluntary, intentional, honest, and directed to one or a few individuals. Then the differences between demonstration and pantomime is analyzed. An important factor is that

Anthropogenic transformation of land globally is threatening water resources in terms of quality and availability. Managing water resources to ensure sustainable utilization is important for a semiarid country such as South Africa. Bayesian networks (BNs) are probabilistic graphical models that have been applied globally to a range of water resources management studies; however, there has been ver

Objective Describe demographical, social and psychological correlates of willingness to receive a COVID-19 vaccine. Setting Series of online surveys undertaken between March and October 2020. Participants A total of 25 separate national samples (matched to country population by age and sex) in 12 different countries were recruited through online panel providers (n=25 334). Primary outcome measures

Objective:The objective of this review was to assess associations between Individual Placement and Support (IPS), employment, and personal and clinical recovery among persons with severe mental illness at 18-month follow-up.Methods:A systematic literature search identified randomized controlled trials (RCTs) comparing IPS with services as usual. Outcomes were self-esteem, empowerment, quality of l

Sleep has evolved as a universal core function to allow for restorative biological processes. Detailed knowledge of metabolic changes necessary for the sleep state in the brain is missing. Herein, we have performed an in-depth metabolic analysis of four mouse brain regions and uncovered region-specific circadian variations. Metabolites linked to oxidative stress were altered during sleep including

BACKGROUND:Lack of mental health literacy among rehabilitation professionals and employers in the return-to-work of persons with mental health problems resulted in the development of a three-day group training program, the Support to Employers from rehabilitation Actors about Mental health (SEAM) intervention.OBJECTIVE:To evaluate the impact of SEAM on rehabilitation professionals’ knowledge and b

Land use is at the core of today’s complex sustainability challenges. Agricultural and environmental economics share a focus land and resource use but evolved in their own domains. Their specialized competencies can be complementary and thus strengthen policy analysis. We use structural topic modelling on more than 24,000 articles in the top agricultural economics and environmental economics journ

Exposure to complex mixtures of environmental contaminants may have severe consequences in free-living animals through the disruption of physiological mechanisms, reduced reproductive outputs and survival, thereby leading to population collapse. Contaminant analyses in fish have been used as a routine approach in studies of aquatic pollution. Located at the upper levels of the food webs, fish are

Streams, rivers and lakes across wide areas of the Northern hemisphere have been subject to an increase in water color over the last decades. This increase, also known as browning, is a result of rising dissolved organic matter (DOM) and iron (Fe) concentrations in the water. Over the years, browning has received ample attention due to its impact on the structure and function of freshwater ecosyst

The green economy with its aim to combine ecological and economic objectives has gained in both significance and political contestation in recent years. In this working paper for the NOWAGG project we revisit the literature on the green economy to understand its implications from a Nordic perspective. Our ambition is to improve the conceptualization of different approaches to green the economy by

This paper is an attempt to provide new perspectives on green energy defaults (GED) that promote the purchase of renewable energy electricity (REe) among consumers. We aim to complement existing studies and improve the understanding of GED, particularly when they are less, or unexpectedly, effective. To that end, we run a randomized controlled experiment and take the UK as a case study. We replica

En dag kommer Covid-19 pandemin att vara en del av vår historia, en del av vår individuella och kollektiva historia. Denna samhällskatastrof förändrade förutsättningarna för det sociala livet, däribland förutsättningarna för att bedriva undervisning på universitetet. I denna text är det studenternas röster som kommer fram. Så som alla andra högskoleutbildningar övergick Socialhögskolan till digita

Ptychography, a scanning coherent diffraction imaging method, can produce a high-resolution reconstruction of a sample and, at the same time, of the illuminating beam. The emergence of vacuum ultraviolet and X-ray free electron lasers (FELs) has brought sources with unprecedented characteristics that enable X-ray ptychography with highly intense and ultra-fast short-wavelength pulses. However, the
