Coherent Diffraction Imaging (CDI) is an experimental technique to image isolated structures by recording the scattered light. The sample density can be recovered from the scattered field through a Fourier Transform operation. However, the phase of the field is lost during the measurement and has to be algorithmically retrieved. Here we present SPRING, an analysis framework tailored to X-ray Free

Background: Magnetic resonance imaging (MRI) is recommended by guidelines to evaluate the severity of brain ischemia after cardiac arrest for functional outcome prediction. However, standardized assessment criteria are lacking. We have developed a semi-quantitative Cardiac Arrest Brain Ischemia (CABI) score to assess the extension of brain ischemia on MRI. Objectives: To evaluate the prognostic pe

Background: Despite its common early onset, little is known about the prevalence and clinical presentation of avoidant restrictive food intake disorder (ARFID) in very young children, hindering early identification and intervention. Differentiating ARFID from normative selective eating is particularly challenging, yet validated parent-reported screening tools are lacking. This study aimed to estim

Introduction: Studies on the association between lipid levels and lipid-lowering treatment and the risk of dementia and/or cognitive decline (CD) have shown conflicting results and are few in individuals with type 2 diabetes (T2D). The aim was to evaluate the relationship of baseline LDL cholesterol levels and statin treatment with the development of dementia/CD in patients with T2D from the Actio

Parids are well-known birds both in Europe and North America. Despite being arboreal foragers of similar size, there is a striking dichotomy in the wintering strategies in the family. Most species are food hoarding specialists that store large amounts of winter food in autumn. A small stable group will then defend a large winter territory in which they store food. From a cognition perspective thes

Background: There has recently been an increased emphasis on patient empowerment and collaboration within their healthcare. However, there is widely a lack of clarity to the concept of empowerment and existing measurement tools lack uniformity, covering diverse domains and related concepts. Objectives: This study aims to conduct a psychometric evaluation of the Swedish version of the Empowerment S

Purpose: To achieve the high sensitivity of digital breast tomosynthesis (DBT), a time-consuming reading is necessary. However, synthetic mammography (SM) images, equivalent to digital mammography (DM), can be generated from DBT images. SM is faster to read and might be sufficient in many cases. We investigate using artificial intelligence (AI) to stratify examinations into reading of either SM or

Purpose: Breast cancer is one of the leading causes of cancer-related deaths among women, and digital mammography plays a key role in screening and early detection. The radiation dose on mammographic exams directly influences image quality and radiologists’ performance. We evaluate the impact of an image restoration pipeline—designed to simulate higher dose acquisitions—on the detectability of mic

Purpose: The purpose is to retrospectively investigate how the addition of prior and concurrent mammograms affects wide-angle digital breast tomosynthesis (DBT) screening false-positive recall rates, malignancy scoring, and recall agreement. Approach: A total of 200 cases were selected from the Malmö Breast Tomosynthesis Screening Trial. They consist of 150 recalled cases [30 true positives (TPs),

Purpose: The purposes are to evaluate the change in mammographic density within individuals across screening rounds using automatic density software, to evaluate whether a change in breast density is associated with a future breast cancer diagnosis, and to provide insight into breast density evolution. Approach: Mammographic breast density was analyzed in women screened in Malmö, Sweden, between 2

The transition to sustainable energy is crucial for modern society, and Reverse Electrodialysis (RED) offers a promising method for harvesting energy from salinity gradients. However, large-scale deployment of RED is constrained by efficiency limitations and the high cost of ion exchange membranes. This study focuses on the development of novel asymmetric cation exchange membranes (CEMs) based on

Synucleinopathies and tauopathies are neurodegenerative disorders characterized by the pathological accumulation of α-synuclein (α-syn) and tau proteins, respectively. These disorders are traditionally managed with symptomatic treatments without addressing the underlying pathologies. Recent advancements in passive immunotherapies, notably the FDA approval of the amyloid-beta (Aβ)-targeting antibod

Monitoring antimicrobial resistance genes (ARGs) in wastewater influents (pre-treatment) and effluents (post-treatment) provides insights into community-level circulation, potential amplification during treatment, and risks associated with gene release into surface waters. Pollutants such as antibiotic residues and microplastics (MPs) may influence ARG dynamics, highlighting the need to assess the

Introduction: Tpeak-Tend interval (Tpe) is considered to be an ECG reflection of the dispersion of repolarization (DOR), and as such has been proposed as a predictor of arrhythmias. In ischemia, robustness of the Tpe-DOR relationship may suffer from variability of the myocardium at risk (MaR) area. In the present study, we evaluated the contribution of DOR and MaR to single‑lead and multi‑lead Tpe

Neuronal accumulation and spread of pathological α-synuclein (α-syn) fibrils are key events in Parkinson's disease (PD) pathophysiology. However, the neuronal mechanisms underlying the uptake of α-syn fibrils remain unclear. In this work, we identified FAM171A2 as a PD risk gene that affects α-syn aggregation. Overexpressing FAM171A2 promotes α-syn fibril endocytosis and exacerbates the spread and

Male childlessness in late adulthood is increasingly prevalent in rural China, indicating a critical need to understand the factors contributing to childlessness among rural men—an often-overlooked group in gerontological and childlessness research. While existing studies have explored individual-level predictors of childlessness over the life course and the implications of broader societal condit

Introduction: Alcohol use has significant health implications, yet the association between alcohol use and respiratory symptoms remains relatively understudied. This study examines the prevalence of hazardous alcohol use and its associations with breathlessness, chronic cough, and health-related quality of life (HRQoL) and whether these associations with chronic airway limitation (CAL) differ by a

This article applies a conceptual framework based on multilevel theories of gender inequality to examine individual-level food insecurity (FI) outcomes in the League of Arab States (LAS). We conceptualize FI as an embodied waypoint on a discriminatory cycle incorporating material and cultural practices that function at macro-, situational-, and individual-levels. Using data drawn from the Gallup W

Aims: Stratifying renal damage in type 2 diabetes is challenging due to overlapping features between diabetic nephropathy (DN) and non-diabetic renal disease (NDRD). While miR-27b-3p modulates kidney fibrosis in DN through the lysine63 ubiquitination pathway, its upstream regulation and diagnostic relevance remain unclear. Methods: In a biopsy-verified cohort of 231 chronic kidney disease (CKD) pa

In 1972 Hajnal and Kertész published a paper proving that the Axiom of Choice is equivalent to the assertion that a groupoid structure can be defined on every set. This thesis aims to provide the necessary background needed for this proof. In the first part basic concepts in set theory such as the Well-Ordering Theorem are derived. This culminates in a lemma by Hartogs (1915) in which it is shown,
