A scoping review of studies in informal second language learning : Trends in research published between 2000 and 2020

In recent years, research interest in second language use and acquisition beyond the classroom has grown considerably. However, terminological confusion and definitional differences have made it difficult to compare findings and discover trends across studies, and more broadly synthesise new insights and developments. Therefore, this scoping review is intended to provide an overview of when, where

Unraveling Molecular and Functional Responses Across 3 Lung Injury Models to Expand the Donor Lung Pool

BACKGROUND: Lung transplantation remains hampered by a scarcity of viable donor lungs, partially attributed to donor lung injuries.METHODS: Three porcine lung injury models were studied: infection-induced using lipopolysaccharide (n = 7), aspiration-induced using endotracheal gastric content (n = 7), and injury using lavage and harmful ventilation (ventilator-induced lung injury; n = 7). Molecular

Adaptive radiotherapy in locally advanced head and neck cancer : The importance of reduced margins

BACKGROUND AND PURPOSE: Adaptive radiotherapy (ART) involves treatment re-planning based on anatomical changes, which may improve target coverage and sparing of organs-at-risk (OARs). This study retrospectively assessed the technical feasibility and potential benefits of daily ART in combination with reduced planning target volume (PTV) margins for head and neck squamous cell carcinoma (HNSCC).MAT

Sleep apnea prevalence and severity after coronary revascularization versus no intervention : a systematic review & meta-analysis

Purpose: Obstructive sleep apnea (OSA) is a common disease in patients with coronary artery disease (CAD). Approximately 40–80% of cardiovascular disease patients have obstructive sleep apnea. The manifestation of it can vary significantly in different types of CAD patients. This systematic review and meta-analysis investigate the prevalence and severity of OSA in patients with acute coronary synd

Perception and acquaintance of stroke specialists on non-inferiority trials : An international survey

Introduction: The adoption of non-inferiority trial designs for assessing new interventions in stroke treatment is on the rise. We designed a survey to assess stroke specialists' understanding and familiarity with non-inferiority trials and margins. Methods: A brief web-based questionnaire was sent to the members of the World Stroke Organization (WSO). The median acceptable non-inferiority margins

Structure and morphology of vesicular dispersions based on novel phosphatidyl glucose and phosphatidyl choline with different acyl chains

Hypothesis: Phospholipids are widely used in food and pharmacological formulations. However, these typically suffer from limitations such as low colloidal stability. Promising stability has been observed for vesicles based on phosphatidylglucose (P-Glu), but fundamental knowledge on this lipid is missing and those observations were made using P-Glu containing mixed acyl groups. The acyl groups are

High-energy-density acoustofluidic device using a double-parabolic ultrasonic transducer

High-acoustic-energy-density acoustofluidic devices are necessary to make this technology a viable option for clinical applications in the biomedical field. We present a mechanical interface that enables delivery of a high-amplitude acoustic field inside a fluid cavity by translating the vibrations from two large piezoelectric elements into a microfluidic chip. The study comprises both experimenta

Monte Carlo dosimetry for a EURADOS WG 10 and RENEB field test of retrospective dosimetry techniques in realistic exposure scenarios

Computational dosimetry using Monte Carlo radiation transport simulations was applied for the 2019 European Radiation Dosimetry Group (EURADOS) and Running the European Network of Biological and retrospective Physical dosimetry (RENEB) field test, an exercise of retrospective dosimetry techniques for a realistic small-scale radiological accident. The simulations were performed at four institutes,

Enough of Fairness : Pre-Emption and the DMA

This chapter looks at the DMA through the prism of pre-emption and the relationship between EU and national law. It explains the fundamentals of pre-emption in EU law and shows the consequences for the DMA and national rules that are to ensure fairness in the digital market space. It argues that fairness in the digital market with regard to business users and consumers has been exhaustively regula

First-in-human, multicenter, open-label, phase I study of ATOR-1017 (evunzekibart), a 4-1BB antibody, in patients with advanced solid malignancies

BACKGROUND: ATOR-1017 (evunzekibart) is a human agonistic immunoglobulin G4 antibody targeting the costimulatory receptor 4-1BB (CD137). ATOR-1017 activates T cells and natural killer cells in the tumor environment, leading to immune-mediated tumor cell death.METHODS: In this first-in-human, multicenter, phase I study, ATOR-1017 was administered intravenously every 21 days as a monotherapy to pati

Stronger effects of accumulated soil moisture deficit on gross primary productivity and light use efficiency than lagged soil moisture deficit for cropland and forest

Many studies have underscored the impacts of drought on ecosystems, and some researchers reported the effects of accumulated soil moisture deficit (ASMD) on light use efficiency (LUE) in grassland. However, the potential effects of ASMD on gross primary productivity (GPP) and LUE for both cropland and forest ecosystems are still not understood. This study elucidated the effects of accumulated and

Emulsification of milk fat and skimmed milk curds – Effect of temperature on rheological properties and structure of emulsion gels at different length scales

There is a need to develop innovative cheese processes to meet consumer demands and improve production efficiency. In this study, rennet skimmed milk curds (SMC), and butter were emulsified using a thermo-mechanical process at temperatures between 70 and 90 °C. The composition, rheological properties, and microstructure of the emulsion gels were analysed up to 2 weeks of storage. Confocal laser sc

Reirradiation in Paediatric Tumours of the Central Nervous System : Outcome and Side Effects After Implementing National Guidelines

Aims: Reirradiation is becoming more frequently used in paediatric tumours of the central nervous system (CNS). To fill the void of clinical guidelines, the Swedish Working Group of Paediatric Radiotherapy compiled consensus guidelines on reirradiation in 2019. The aim of this study was to evaluate the outcome of children reirradiated for CNS tumours since implementing the guidelines. Material and

Microbial communities in slow sand filters for drinking water treatment adapt to organic matter altered by ozonation

Changing natural organic matter quality from anthropogenic activity and stricter requirements for micropollutant removal challenges existing systems for drinking water production. Ozonation of water followed by biofiltration, such as passage through a slow sand filter (SSF), is a partial solution. Biofiltration relies on biofilms (microbial communities within extracellular matrices). However, the

Deferral of left main coronary artery revascularization via IVUS or coronary physiology - Long-term outcomes from the SWEDEHEART registry

Background: Intravascular ultrasound (IVUS) guides deferral decision-making regarding the left main coronary artery (LMCA) and improves outcomes. Further studies regarding coronary physiology to guide revascularization in the LMCA are needed. Our aim was to evaluate the outcome of LMCA deferral using IVUS or coronary physiology via instantaneous wave-free ratio (iFR) or fractional flow reserve (FF

The escape from hunger: The impact of food prices on well-being in Sweden, 1813–1967

This study analyses how the standard of living for different social groups changed when Sweden developed from an agricultural to an industrial society and when the first steps towards a modern welfare society were taken. As a measure of living standards, we use the ability to overcome short-term economic stress caused by high food prices. We use individual-level longitudinal data from 1813 to 1967
