A self-sustaining layer of early-life-origin B cells drives steady-state IgA responses in the adult gut

The adult immune system consists of cells that emerged at various times during ontogeny. We aimed to define the relationship between developmental origin and composition of the adult B cell pool during unperturbed hematopoiesis. Lineage tracing stratified murine adult B cells based on the timing of output, revealing that a substantial portion originated within a restricted neonatal window. In addi

Mind Wandering and Sleep in Daily Life: A Combined Actigraphy and Experience Sampling Study

Individuals who sleep poorly report spending more time mind wandering during the day. However, past research has relied on self-report measures of sleep or measured mind wandering during laboratory tasks, which prevents generalization to everyday contexts. We used ambulatory assessments to examine the relations between several features of sleep (duration, fragmentation, and disturbances) and mind

Childhood Diarrhea Prevalence and Uptake of Oral Rehydration Solution and Zinc Treatment in Nigeria

Given the disproportionate burden of childhood diarrhea deaths in Nigeria, this study assessed the prevalence and predictors of the disease and the uptake of ORS and zinc supplementation as treatments in a population-based national survey. Cross-sectional data from the 2018 Nigeria Demographic Health Survey were used. A log-Poisson regression was used to estimate the relative risks (RR) for the in

Freely Available, Fully Automated AI-Based Analysis of Primary Tumour and Metastases of Prostate Cancer in Whole-Body [18F]-PSMA-1007 PET-CT

Here, we aimed to develop and validate a fully automated artificial intelligence (AI)-based method for the detection and quantification of suspected prostate tumour/local recurrence, lymph node metastases, and bone metastases from [18F]PSMA-1007 positron emission tomography-computed tomography (PET-CT) images. Images from 660 patients were included. Segmentations by one expert reader were ground t

The complement receptor C3AR constitutes a novel therapeutic target in NPM1-mutated AML

Mutated Nucleophosmin 1 (NPM1) is the most common genetic alteration in acute myeloid leukemia (AML), found in approximately 30% of cases. Although mutations in this gene are considered favorable according to current risk stratification guidelines, a large fraction of patients will suffer from relapse, demonstrating the urgent need for new treatment options. Therefore, we aimed to identify cell su

Oncologic Emergencies: : Pathophysiology, Diagnosis, and Initial Management

The rate of cancer patients will continue to increase in the coming decades. Additionally, new treatments will continue to emerge. The increased survival rates and the anti-tumour medications used will without doubt contribute to an increased rate of patients with oncological emergencies. Patients with oncologic emergencies will foremost seek care at an emergency department, but physicians at othe

Explore or exploit? Unpacking the situational conditions and cognitive mechanisms underlying entrepreneurial learning in the new venture development process

This study explores when and why entrepreneurs choose entrepreneurial learning strategies that emphasize exploration or exploitation. Most studies have focused on explaining the different characteristics of exploration and exploitation, their performance implications, whether they are complementarities or substitutes and how particular organizational structures can support their coexistence. We ap

”Jag kan leva på detta!” : Utmaningar och möjligheter med arbetet som influencer

Det här kapitlet undersöker fenomenet influencers från ett arbetslivsperspektiv. Den kulturanalytiska utgångspunkten är ett intresse för hur personer som försörjer sig som influencers i sociala medier själva upplever arbetet, det liv som arbetet innebär och de hälsorisker det medför. Forskning om influencers har ofta haft ett annat fokus, såsom ett marknadsföringsperspektiv som beskriver hur föret

Event segmentation in the audio description of films : A case study

To make the content of moving images and audio-visual media available to a visually impaired audience, a sighted interpreter can provide audio description (AD). AD is a verbal description of visual events, aiming to increase the accessibility of visual information and to provide a visually impaired audience with a richer and more detailed understanding and experience of, for instance, films. To ac

The European Spallation Source neutrino super-beam conceptual design report

A design study, named $${\text {ESS}}\nu {\text {SB}}$$for European Spallation Source neutrino Super Beam, has been carried out during the years 2018–2022 of how the 5 MW proton linear accelerator of the European Spallation Source under construction in Lund, Sweden, can be used to produce the world’s most intense long-baseline neutrino beam. The high beam intensity will allow for measuring the neuA design study, named ESSνSB for European Spallation Source neutrino Super Beam, has been carried out during the years 2018–2022 of how the 5 MW proton linear accelerator of the European Spallation Source under construction in Lund, Sweden, can be used to produce the world’s most intense long-baseline neutrino beam.
