Minimal so(10) near the edge : The importance of being effective

The minimal SO(10) grand unified theory, augmented by higher-dimensional operators, is based on the following Higgs representations: adjoint 45H, spinor 16H, and complex vector 10H. It was recently realized that, as opposed to the conventional wisdom, any intermediate mass scale has to lie close to the grand unification one. This bears profound consequences for the scalar particles mass spectrum a

Development of MHz X-ray phase contrast imaging at the European XFEL

We report on recent developments that enable megahertz hard X-ray phase contrast imaging (MHz XPCI) experiments at the Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) instrument of the European XFEL facility (EuXFEL). We describe the technical implementation of the key components, including an MHz fast camera and a modular indirect X-ray microscope sys

Fear extinction retention in children, adolescents, and adults

Past results suggest that fear extinction and the return of extinguished fear are compromised in adolescents. However, findings have been inconclusive as there is a lack of fear extinction and extinction retention studies including children, adolescents and adults. In the present study, 36 children (6–9 years), 40 adolescents (13–17 years) and 44 adults (30–40 years), underwent a two-day fear cond

The Regulatory Role of Pancreatic Enzymes in the Maintenance of Small Intestinal Structure and Enterocyte Turnover with Special Reference to Alpha Amylase

The aim of this study was to elucidate the impact of porcine pancreatic enzymes (Creon® pancrelipase) in comparison to microbial-derived alpha amylase (MD amylase) on the small intestine wall structure, mucosal glycogen accumulation, and enterocyte turnover. The impact of enzyme supplementation on the small intestine was explored in 18 pigs with surgically induced exocrine pancreatic insufficiency

Non-viable embryos created with synthetic DNA

It is plausible that in the future synthetic DNA (synDNA) technology could enable the creation of non-viable embryos for research, potentially bypassing ethical objections to embryo experimentation. This article explores how the technology might work, the ethical concerns it might mitigate, and the challenges that remain.

Maintaining operability at a high personal cost – a mixed method study on maternal healthcare workers’ experiences during the COVID-19 pandemic

Introduction: The COVID-19 pandemic forced leaders and employees in health care services to take difficult decisions to manage risks associated with employee health and the organizations’ functioning. This study aims to identify the changes in employee working routines, job demands, and job resources within Swedish maternal healthcare during the COVID-19 pandemic, and how these changes affected wo

Characterisation of heritable TP53-related cancer syndrome in Sweden—a nationwide study of genotype-phenotype correlations in 90 families

We aimed to describe the clinical characteristics of families with heritable TP53-related cancer (hTP53rc) syndrome in Sweden with class 4 and 5 germline TP53 variants (gTP53), and to evaluate the genotype-phenotype correlation. These results were also used to evaluate our previously published phenotype prediction model based on TP53 missense variants and their impact on protein conformation. 90 f

Human monocyte subtype expression of neuroinflammation- and regeneration-related genes is linked to age and sex

Aging profoundly affects the immune system leading to an increased propensity for inflammation. Age-related dysregulation of immune cells is implicated in the development and progression of numerous age-related diseases such as: cardiovascular diseases, neurodegenerative disorders, and metabolic syndromes. Monocytes and monocyte-derived macrophages, being important players in the inflammatory resp

Percutaneous vs. surgical revascularization of non-ST-segment elevation myocardial infarction with multivessel disease : the SWEDEHEART registry

Background and Aims The long-term outcomes of percutaneous coronary intervention (PCI) vs. coronary artery bypass grafting (CABG) in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and multivessel disease remain debated. Methods The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registry

Outcome of follow-up computed tomography of suspected occult scaphoid fracture after normal radiography

Purpose: To evaluate the rate of missed scaphoid fractures on follow-up computed tomography (CT) for suspected occult scaphoid fracture after normal radiography with residual radial-sided wrist pain. Methods: In a retrospective analysis, wrist CT during a five-year period was analyzed. The CT examinations and radiological reports were re-evaluated. Available clinical findings and radiologic follow

A Window to the Past: Living standards in historical perspective

Real wages are a convenient, useful, and powerful way to learn how life was like in the past. In this chapter we start by reviewing the methodology behind real wage estimations and their history. Then we look at the how real wages have contributed to shedding light on major issues in economic history such as the onset of modern economic growth, the Great Divergence, and colonialism in the Americas

Prediction of survival after pancreatoduodenectomy for distal cholangiocarcinoma : independent external validation of a prognostic model for 3-year overall survival in Sweden

Objectives: The only treatment with curative potential for distal cholangiocarcinoma (dCCA) is radical surgery which can be complemented with adjuvant chemotherapy. The aim of the present study was to perform an independent external validation of a prognostic model for 3-year overall survival based on routine clinicopathological variables for patients treated with pancreatoduodenectomy for dCCA. M

Nanoplastic in aqueous environments : The role of chemo-electric properties for nanoplastic-mineral interaction

Due to increasing plastic production, the continuous release of primary and secondary nanoplastic particles (NPs, <1 μm) has become an emerging contaminant in terrestrial environments. The fate and transport of NPs in subsurface environments remain poorly understood, largely due to the complex interplay of mineralogical, chemical, biological, and morphological heterogeneity. This study examines in

Impact of mild hypercapnia on renal function after out-of-hospital cardiac arrest

Background: Acute kidney injury (AKI) is a serious complication of out-of-hospital cardiac arrest (OHCA). Post-resuscitation cardiogenic shock (CS) is a key contributing factor. Targeting a higher arterial carbon dioxide tension may affect AKI after OHCA in patients with or without CS. Methods: Pre-planned exploratory study of a multi-national randomised trial comparing targeted mild hypercapnia o

Olfaction with legs—Spiders use wall-pore sensilla for pheromone detection

The sense of smell is a central sensory modality of most terrestrial species. However, our knowledge of olfaction is based on vertebrates and insects. In contrast, little is known about the chemosensory world of spiders and nothing about how they perform olfaction despite their important ecological role. The orb-weaving spider Argiope bruennichi lends itself to an in-depth study on olfaction as it

The Distinct Seasonality of Early Modern Casual Labor and the Short Durations of Individual Working Years: Sweden 1500–1800

This paper makes use of nearly 25,000 observations representing over 95,000 paid workdays across over 300 years to investigate individual work patterns, work availability, and the changes in work seasonality over time. This sample is comprised of workers in the construction industry, and includes unskilled men and women as well as skilled building craftsmen – the industry which is often used to es

Impact of smoking status on engagement in remote symptom monitoring after oncologic surgery : Implications for symptom management and readmission rates

Background: Remote symptom monitoring (RSM) is an evidence-based strategy shown to mitigate postoperative morbidity; however, platform engagement is required to benefit from RSM. Patients who report current smoking are at high risk for postoperative complications, but it is unknown whether smoking status influences engagement with RSM, symptom severity, or unanticipated acute care visits. Methods:
