Global drivers of avian haemosporidian infections vary across zoogeographical regions

Aim: Macroecological analyses provide valuable insights into factors that influence how parasites are distributed across space and among hosts. Amid large uncertainties that arise when generalizing from local and regional findings, hierarchical approaches applied to global datasets are required to determine whether drivers of parasite infection patterns vary across scales. We assessed global patte

Study region: Two hyper-arid regions (Atbara and Kassala stations) in Sudan. Study focus: The study aims to evaluate the potential of the D-vine Copula-based quantile regression (DVQR) model for estimating daily ETo during 2000–2015 based on various input structures. Further, the DVQR model was compared with Multivariate Linear quantile regression (MLQR), Bayesians Model Averaging quantile regress

Multiscale Modelling of Atomistic Structure of Calcium Silicate Hydrate

The atomistic structure of calcium-silicate-hydrate (C-S-H) has been studied by applying force field simulations and quantum mechanical methods. Large number of crystallographically equivalent structures were used to account for the disordered nature of C-S-H. An extensive set of periodic structures of C-S-H (with a variation of chemical composition) has been generated and optimised. Special att

Cardiac Arrest Treatment Center Differences in Sedation and Analgesia Dosing During Targeted Temperature Management

Background: Sedation and analgesia are recommended during targeted temperature management (TTM) after cardiac arrest, but there are few data to provide guidance on dosing to bedside clinicians. We evaluated differences in patient-level sedation and analgesia dosing in an international multicenter TTM trial to better characterize current practice and clinically important outcomes. Methods: A total

Risk factors for multisystem inflammatory syndrome in children – A population-based cohort study of over 2 million children

Background: Although severe acute COVID-19 is rare in children, SARS-CoV-2 infection can trigger the novel post-infectious condition multisystem inflammatory syndrome in children (MIS-C). Increased knowledge on risk factors for MIS-C could improve our understanding of the pathogenesis of the condition and better guide targeted public health interventions. The aim of the study was to assess risk fa

Individual’s risk attitudes in sub-Saharan Africa : Determinants and reliability of self-reported risk in Burkina Faso

Understanding individual risk taking is an important topic in Africa, as access to financial institutions and social security is scarce, and where markets and government policies largely fail to understand investment decisions of poor households. Data on risk attitudes in Africa is limited and the available data collected might not be reliable.

Real-world Treatment Sequencing in Patients with Metastatic Castration-resistant Prostate Cancer : Results from the Prospective, International, Observational Prostate Cancer Registry

Background: Prostate cancer has a multifaceted treatment pattern. Evidence is lacking for optimal treatment sequences for metastatic castration-resistant prostate cancer (mCRPC). Objective: To increase the understanding of real-world treatment pathways and outcomes in patients with mCRPC. Design, setting, and participants: A prospective, noninterventional, real-world analysis of 3003 patients with

Comment on ‘Pendulum: the partial and global approach’

The paper Pendulum: the partial and global approach combines a historic introduction to the theoretical treatment of pendulum motion with presentation of data from measurements on a single pendulum. This comment focuses on the presentation and analysis of experimental data, and how the use of dimensionless variables in graphs would make use of the mathematical properties, placing the single measur

Liminal Children, Liminal Rights? : Media Representations of Scandinavian Children Born of War after World War II and after the Fall of the Islamic State

This chapter argues for the importance of developing historical reference frames for Scandinavian children born to foreign fighters in the so-called Islamic State (IS)—that is, seeing them as children born of war (CBOW) rather than as “IS children”—to strengthen the case for their repatriation from Kurdish detention camps. Politicians across the region today stress they want to repatriate the chil

CT is unreliable in locoregional staging of early colon cancer : A nationwide registry-based study

BACKGROUND AND OBJECTIVE: The option to treat early colon cancer (CC) with local resection, as well as trials investigating neoadjuvant treatment, has increased the importance of identifying early-stage disease in the workup. Most CC patients are T- and N-staged preoperatively with CT, although its reliability in staging early CC remains elusive. The aim of this study was to investigate CT-staging

S100A9 induces reactive oxygen species-dependent formation of neutrophil extracellular traps in abdominal sepsis

Recent evidence suggests that targeting S100A9 reduces pathological inflammation in abdominal sepsis. Herein, we investigated the role of S100A9 in neutrophil extracellular trap (NET) formation in septic lung damage. NETs were detected by electron microscopy in the lung and by confocal microscopy in vitro. Stimulation of isolated mouse bone marrow-derived neutrophils with S100A9 triggered formatio

The abortion divide: Exploring the role of exclusion, loss of significance and identity in the radicalization process

Introduction: Recently, the abortion issue has entered the spotlight in the USA, leading to potential radical actions. As the majority opinion on the abortion issue vary with state, some individuals will be in the numerical minority within their state, possibly evoking feelings of exclusion. Social exclusion can motivate a radicalization process. The aim of this paper is to explore how individuals

Hälsofrämjande och förebyggande arbete med fokus på högstadieelever under COVID-19 pandemin utifrån skolsköterskans perspektiv

Bakgrund: När COVID-19 pandemin bröt ut i Sverige i början av 2020 vidtog regering ett stort antal beslut och åtgärder beträffande skolorna. Periodvis digital undervisning för högstadieskolor, minskad fysisk aktivitet och social isolering ledde till ett ökat lidande med oro, stress och ångest hos en del barn. Skolsköterskan ställdes inför helt nya utmaningar i sitt hälsofrämjande och förebyggande Background: When the COVID-19 pandemic broke out in Sweden at the beginning of 2020, the government took a large number of decisions and measures regarding the schools. Periodic digital teaching for junior high schools, reduced physical activity and social isolation led to increased suffering with worry, stress and anxiety in some children. The school nurse was faced with completely new challenges

A highly sensitive bead-based flow cytometric competitive binding assay to detect SARS-CoV-2 neutralizing antibody activity

Accurate detection of SARS-CoV-2 neutralizing antibody (nAb) is critical for assessing the immunity levels after virus infection or vaccination. As fast, cost-effective alternatives to viral infection-based assays, competitive binding (CB) assays were developed to quantitate nAb by monitoring the ability of sera to inhibit the binding of viral spike (S) protein to the angiotensin converting enzyme

The human TRPA1 intrinsic cold and heat sensitivity involves separate channel structures beyond the N-ARD domain

TRP channels sense temperatures ranging from noxious cold to noxious heat. Whether specialized TRP thermosensor modules exist and how they control channel pore gating is unknown. We studied purified human TRPA1 (hTRPA1) truncated proteins to gain insight into the temperature gating of hTRPA1. In patch-clamp bilayer recordings, ∆1-688 hTRPA1, without the N-terminal ankyrin repeat domain (N-ARD), wa

Polarization vision mitigates visual noise from flickering light underwater

In shallow water, downwelling light is refracted from surface waves onto the substrate creating bands of light that fluctuate in both time and space, known as caustics. This dynamic illumination can be a visual hindrance for animals in shallow underwater environments. Animals in such habitats may have evolved to use polarization vision for discriminating objects while ignoring the variations in il

David vs. Coal-iath: Coalition-building in the anti-coal protests in Lützerath, Germany

For social movements to create social change they need to mobilize resources, seize political opportunities, and foster favourable discourses. To do so, they engage in coalition building processes to streamline their action and resources with related groups. This process can also be observed in the village of ‘Lützerath’, Germany, which shall be swallowed by the coal mine ‘Garzweiler 2’. To analys

The Gaia-ESO Survey : Oxygen Abundance in the Galactic Thin and Thick Disks

We analyze the oxygen abundances of a stellar sample representative of the two major Galactic populations: the thin and thick disks. The aim is to investigate the differences between members of the Galactic disks and contribute to the understanding of the origin of oxygen chemical enrichment in the Galaxy. The analysis is based on the [O i] = 6300.30 Å oxygen line in high-resolution spectra (R ∼ 5

Assessing change agency in urban experiments for sustainability transitions

Experimentation has become one of the prevailing modes of governing the transition toward sustainable practices in urban environments. The spatial variation of urban sustainability transition has been attributed to a variety of conditions erected at different spatial scales. What remains less well-understood is how spatial situatedness shapes agency in urban experiments and the shapes agency can t

Planning for sustainable urban livelihoods in Africa

This chapter explores the role, success and failures of spatial planning in shaping African cities and its influence on livelihoods. To date, planning in Africa has largely failed to address the needs and livelihoods of the poor and struggled to address wider issues such as spatial and economic inclusion, health inequalities, future pandemics and climate change.
