Background: Guidance on managing acute mesenteric ischaemia (AMI) is largely based on expert opinion and retrospective studies pooling different subtypes of AMI. In clinical practice, management strategy is often selected based on the patient’s severity of illness, whereas randomized controlled trials or even adjusted analyses comparing different strategies are rarely available. We aimed to perfor
Selective inheritance of sub-cellular components has emerged as a mechanism guiding stem cell fate after asymmetric cell divisions. Peroxisomes play a crucial role in multiple metabolic processes such as fatty acid metabolism and reactive oxygen species detoxification, but the apportioning of peroxisomes during stem cell division remains understudied. Here, we develop a mouse model and labeling te
Global climate change is characterized by increasing and differentiated exposure to climate-related hazards such as floods, landslides, avalanches, storms, and wildfires (IPCC 2018, 2022). There is a significant volume of research on the effects of such events, and over the last decade, much of this research has been directed at where most lives and values can be saved by protective measures (e.g.
Cities typically treat migration and sustainability as separate policy domains. When migration is highlighted in the context of sustainability in urban destination areas, it is typically understood to have no, or at worst, negative impacts on sustainability. As a result, migration and migrants are commonly left out of sustainability policy and planning. Here, we present emerging evidence to refram
Acute coronary syndrome (ACS), including acute myocardial infarction (AMI), are a leading cause ofmorbidity and mortality worldwide. Accurate risk evaluation in patients presenting with chest pain isessential for optimizing emergency department (ED) resource allocation and patient outcomes. Currentclinical decision support tools rely on structured risk scores and biomarker measurements, such as hi
Methods: Three hundred and eighty newly diagnosed ANCA-associated vasculitis patients from six European multicentre studies treated with AZA maintenance were included; 58% were male, median age at diagnosis 59.4 years (interquartile range: 48.3-68.2 years); granulomatosis with polyangiitis, n = 236; microscopic polyangiitis, n = 132; or renal limited vasculitis, n = 12. Patients were grouped accor
5-Fluorouracil (5FU) is a fluoropyrimidine used for the treatment of solid tumors. 5FU is a precursor of dTTP and UTP during biogenesis, and it interferes with both DNA and RNA metabolism. The RNA exosome, a multisubunit complex with ribonucleolytic activity, has been identified as one of the targets of 5FU in yeast. Studies in human cells have shown that the catalytic subunit of the nuclear exoso
Expression of minigenes encoding tetra- or pentapeptides MXLX or MXLXV (E peptides), where X is a nonpolar amino acid, renders cells erythromycin resistant whereas expression of minigenes encoding tripeptide MXL does not. By using a 3A' reporter gene system beginning with an E-peptide-encoding sequence, we asked whether the codons UGG and GGG, which are known to promote peptidyl-tRNA drop-off at e
There is a widening gap between the fast advancement of computational methods for tomographic reconstruction and their successful implementation in production software at various synchrotron facilities. This is due in part to the lack of readily available instrument datasets and phantoms representative of real materials for validation and comparison of new numerical methods. Recent advancements in
Natural light-harvesting is performed by pigment–protein complexes, which collect and funnel the solar energy at the start of photosynthesis. The identity and arrangement of pigments largely define the absorption spectrum of the antenna complex, which is further regulated by a palette of structural factors. Small alterations are induced by pigment–protein interactions. In light-harvesting systems
The high variability in the hydrological regime of the Eastern Hydrological Region (EHR) of Northeast Brazil often results in floods and droughts, leading to serious socio-economic issues. Therefore, this work aimed to investigate connections between spatiotemporal hydrological variability of the EHR and large-scale climate phenomena. Multivariate statistical techniques were applied to relate clim
The issue of Critical Raw Materials (CRMs) and potential interruptions to their availability due to shortages, trade restrictions or other factors in their supply are topics that are relatively unknown to the general public. For this reason, education has been promoted as a key enabler of a circular economy. One key intervention point is the movement of electronic repair events. Repair events alre
Hypomyelination is observed in the context of a growing number of genetic disorders that share clinical characteristics. The aim of this study was to determine the possible role of magnetic resonance imaging pattern recognition in distinguishing different hypomyelinating disorders, which would facilitate the diagnostic process. Only patients with hypomyelination of known cause were included in thi
Early aetiological diagnosis is of paramount importance for childhood dystonia because some of the possible underlying conditions are treatable. Numerous genetic and non-genetic causes have been reported, and diagnostic workup is often challenging, time consuming and costly. Recently, a paradigm shift has occurred in molecular genetic diagnostics, with next-generation sequencing techniques now all
Recent evidence has shown that D-amino acids are present in animals and humans in high concentrations and fulfill specific biological functions. In the central nervous system, two D-amino acids, D-serine and D-aspartate, occur in considerable concentrations. D-Serine is synthesized and metabolized endogenously and the same might account for D-aspartate. D-Serine has been studied most extensively a
Early caregiving is one of the strongest influences on children's development, and among the most significant modifiable environmental factor. The aim of this study was to explore the association between quality of caregiver-infant interactions and neurodevelopment of infants living in banana-growing communities in rural Costa Rica characterized as having environmental toxic exposures.

A person's lipid profile is influenced by genetic variants and alcohol consumption, but the contribution of interactions between these exposures has not been studied. We therefore incorporated gene-alcohol interactions into a multiancestry genome-wide association study of levels of high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides. We included 45 studies
