Simultaneous rheological, polarized light imaging, and small-angle X-ray scattering experiments (Rheo-PLI-SAXS) are developed, thereby providing unprecedented level of insight into the multiscale orientation of hierarchical systems in simple shear. Notably, it is observed that mesoscale alignment in the flow direction does not develop simultaneously across nano-micro lengthscales in sheared suspen
Background: Two risk factors for severe retinopathy of prematurity (ROP) in extremely preterm infants are thrombocytopenia and low levels of arachidonic acid (AA) and docosahexaenoic acid (DHA). To date, these risk factors have not been linked. Method: Infants born < 28 weeks gestational age (GA) from 2016 to 2019 were randomized to postnatal enteral AA/DHA supplementation or standard care (contro
Background: Endocrine disrupting chemicals (EDCs) can cross the placenta and thereby expose the fetus, which may lead to developmental consequences. It is still unclear which chemicals are of concern regarding neurodevelopment and specifically behaviour, when being exposed to a mixture. Objective: The objective is to determine associations between prenatal exposure to EDCs and behavioural difficul
Det globala akademiska landskapet har förändrats avsevärt sedan 1990-talet. Idag deltar fler länder än någonsin i produktionen av forskning av hög kvalitet, och internationella samarbeten inom högre utbildning har ökat markant under de senaste tre årtiondena på grund av globalisering och ökad personmobilitet. Det är tydligt att internationella utbyten och ökad personmobilitet har stärkt Sveriges fThe global academic landscape has changed significantly since the 1990s. Today, more countries than ever participate in the production of high-quality research, and international collaborations in higher education have increased dramatically over the past three decades due to globalization and increased personal mobility. It is clear that international exchanges and increased personal mobility hav

Newts have large genomes harboring many repeat elements. How these elements shape the genome and relate to newts' unique regeneration ability remains unknown. We present here the chromosome-scale assembly of the 20.3 Gb genome of the Iberian ribbed newt, Pleurodeles waltl, with a hitherto unprecedented contiguity and completeness among giant genomes. Utilizing this assembly, we demonstrate conserv
INTRODUCTION: Despite predicted efficacy, immunotherapy in epithelial ovarian cancer (EOC) has limited clinical benefit and the prognosis of patients remains poor. There is thus a strong need for better identifying local immune dynamics and immune-suppressive pathways limiting T-cell mediated anti-tumor immunity.METHODS: In this observational study we analyzed by immunohistochemistry, gene express
BACKGROUND: Canine gastroenteritis (CGE) is a common cause for seeking veterinary care in companion animal medicine and an area where antibiotics have been reported to be widely used. Therefore, creating relevant benchmarks for antibiotic use in CGE is important when implementing and analyzing antibiotic stewardship interventions. The aim of this paper was to describe the level and temporal trend
BACKGROUND: The incidence of colorectal cancer (CRC) in individuals of fertile age is increasing. Oxaliplatin is a cornerstone treatment in the adjuvant setting for stage III and high-risk stage II CRC. Limited data exist on possible side effects of oxaliplatin on fertility and gonadal function. More data is needed to guide possible fertility preservation procedures and aid evidence-based fertilit
Nonsteroidal anti-inflammatory drugs (NSAIDs) can damage the gastrointestinal tract, causing widespread morbidity and mortality. Although mechanisms of damage involve the activities of prostaglandin-endoperoxide synthase 1 (PTGS1 or cyclooxygenase [COX] 1) and PTGS1 (COX2), other factors are involved. We review the mechanisms of gastrointestinal damage induction by NSAIDs via COX-mediated and COX-
INTRODUCTION: Much of what we know about the functioning of human T lymphocytes is based on the experiments carried out in atmospheric oxygen (O₂) concentrations, which are significantly higher than those maintained in blood. Interestingly, the gender differences in the activity of T cells and their susceptibility to apoptosis under different O₂ conditions have not yet been described. The aim of t
Increased radioactivity in the near-surface atmosphere is virtually an annual occurrence in the Gomel region, Belarus. However, there is no explicit evidence as to what causes these anomalies and whether their origin has a strong seasonal association. To establish any such relations, we have analysed long-term radiation monitoring data recorded in the region over the past 17 years from 2003 to 202
BACKGROUND: Heart failure (HF) is a common chronic condition that affects over 26 million people worldwide. It is a progressive and debilitating disease with a broad symptom profile, intermittently marked by periods of acute decompensation. People with HF generally do not self-manage their condition well (eg, monitoring symptoms, taking medications regularly, physical activity, etc). A better unde
Changes in hydration status may affect myocardial native T1 and T2 values and influence the clinical interpretation. We aimed to assess the impact of acute preload augmentation on native T1 and T2. Cardiovascular magnetic resonance (CMR) native T1 and T2 mapping were performed twice on the same day in 20 healthy participants before and after an acute preload augmentation by a 2-liter intravenous i
In response to the growing demand for sustainable practices in the hospitality industry, many hotels have concentrated on operational measures to reduce energy consumption. However, the potential for promoting voluntary customer-initiated energy-saving behaviors has been largely overlooked. This study fills that gap by investigating how environmental values (egoistic, altruistic, and biospheric) a
Haemolysis occurring during cardiac surgery with cardiopulmonary bypass (CPB) is assumed to be a risk factor for postoperative acute kidney injury (AKI). Plasma alpha-1 microglobulin (A1M) may have a protective role as haem scavenger. The aim of this study was to evaluate the association between AKI and the degree of haemolysis and the course of A1M concentrations during cardiac surgery, respectiv
Antimicrobial resistance is one of the largest threats to global health. In society as well as in healthcare facilities, antimicrobial resistance is rapidly increasing with the main reason being overuse and misuse of antibiotics combined with inadequate infection prevention. For humans, dental care accounts for about 10% of all antibiotic prescriptions, making it an important target for antibiotic
Optimal blood flow through a patent cerebral circulation is critical for supply of oxygen and nutrients for brain function. The integrity of vascular elements within arterial vessels of any calibre can be compromised by various disease processes. Pathological changes in the walls of veins and the venous system may also alter the dynamics of cerebral perfusion. The consequences of both systemic vas
Mitotic cells attenuate the DNA damage response (DDR) by phosphorylating 53BP1, a critical DDR mediator, to prevent its localization to damaged chromatin. Timely dephosphorylation of 53BP1 is critical for genome integrity, as premature recruitment of 53BP1 to DNA lesions impairs mitotic fidelity. Protein phosphatase 4 (PP4) dephosphorylates 53BP1 in late mitosis to allow its recruitment to DNA les
