Determinants of urinary pesticide metabolite concentrations in school-aged children from rural Bogotá, Colombia

This study aimed to determine urine pesticide metabolite concentrations using liquid chromatography and investigate associated exposure factors in a rural area of Bogotá, Colombia. In 2019, 231 urine samples were collected from children aged 7 to 10. Urinary pesticide metabolite concentrations were measured, and a questionnaire was administered to the children’s mothers to collect exposure-related

A Compact Chemical Kinetic Mechanism for Heavy Fuel Surrogates with n-, iso- and cyclo-Alkanes, and Aromatic Compounds

Modeling of real-world fuels and fuel mixtures in combustion engines, using computational fluid dynamics (CFD), calls for the development of compact and computationally efficient chemical kinetic mechanisms. To improve the modeling capabilities of multicomponent fuels it is necessary to transition from the single-component descriptions of fuels and move toward more complex, accurate multicomponent

Synthesis and In Vitro Profiling of Psilocin Derivatives : Improved Stability and Synthetic Properties

As interest in using psilocybin therapy for treating mental health disorders intensifies, the need for efficient production methods becomes increasingly important. Current medical-grade psilocybin production is inefficient and relies on a complicated multistep synthesis. This study has explored and evaluated psilocin ester prodrugs and psilocin salts as potential alternatives to psilocybin, focusi

Computed tomography grey-white matter ratio at the basal ganglia level in a reference population for hypoxic ischaemic encephalopathy after cardiac arrest – A cross-sectional observational study

Introduction: A grey-white matter ratio (GWR) < 1.10 at the basal ganglia level on head computed tomography (CT) previously predicted poor outcome with high specificity and moderate sensitivity in cardiac arrest patients. Data on GWR in reference populations are lacking. We explored GWR in a reference group to a cardiac arrest population and hypothesised that none would have GWR < 1.10. Methods: A

Blood methylome signatures in children exposed to maternal type 1 diabetes are linked to protection against islet autoimmunity

Exposure to maternal type 1 diabetes (T1D) during pregnancy provides relative protection against T1D in the offspring. This protective effect may be driven by epigenetic mechanisms. Here we conducted an epigenome-wide blood analysis on 790 young children with and 962 children without a T1D-affected mother, and identified differential DNA methylation (q < 0.05) at multiple loci and regions. These i

Patriarchal securitization : epistemic domination in the politics of European agriculture

This article examines how the securitization of food production in the European Union (EU) reinforces patriarchal authority and epistemic exclusion. Building on feminist security studies, it analyzes how discourses of ‘food security’ elevate masculinized figures of authority–farmers cast as protectors and providers–while marginalizing alternative knowledges of care, sustainability, and glob al jus

Airborne fungal spore concentrations double but diversity decreases with warmer winter temperatures in the Brazilian Atlantic Forest biodiversity hotspot

Whilst research on climatic effects on fungal populations and communities (particularly of soil and litter-specialised species) has been done extensively, empirical examples of the impacts of climate change on airborne fungi are still lacking. Using a hot-air balloon to sample fungal spores during the winters of 2022 and 2023, here, we show the effects of warmer winter temperatures on airborne fun

Trajectory-Ordered Objectives for Self-Supervised Representation Learning of Temporal Healthcare Data Using Transformers : Model Development and Evaluation Study

Background: The growing availability of electronic health records (EHRs) presents an opportunity to enhance patient care by uncovering hidden health risks and improving informed decisions through advanced deep learning methods. However, modeling EHR sequential data, that is, patient trajectories, is challenging due to the evolving relationships between diagnoses and treatments over time. Significa

Precession modulates the poleward expansion of atmospheric circulation to the Arctic Ocean

Under sustained global warming, Arctic climate is projected to become more responsive to changes in North Pacific meridional heat transport as a result of teleconnections between low and high latitudes, but the underlying mechanisms remain poorly understood. Here, we reconstruct subarctic humidity changes over the past 400 kyr to investigate the role of low-to-high latitude interactions in regulat

MIFA : Metadata, Incentives, Formats and Accessibility guidelines to improve the reuse of AI datasets for bioimage analysis

Artificial intelligence (AI) methods are powerful tools for biological image analysis and processing. High-quality annotated images are key to training and developing new algorithms, but access to such data is often hindered by the lack of standards for sharing datasets. We discuss the barriers to sharing annotated image datasets and suggest specific guidelines to improve the reuse of bioimages an

Four methods of hydrogen combustion within combined heat and power plants to increase power output

In recent years, there has been an increasingly larger fraction of intermittent energy sources. In the northern parts of Europe, the main source of intermittent power is wind power. This source of power is low inertia, inconsistent and will always fluctuate with different magnitudes, leaving a need for balancing. One source of balancing is to have the widespread non-zero inertia combined heat and

Validation of the IHE type 2 diabetes cohort model in the Japanese clinical setting

Aims: Economic simulation models, such as the IHE Type 2 Diabetes Cohort Model (IHE-DCM-T2), are used widely to inform resource allocation for Type 2 Diabetes (T2D) treatments. Recently, IHE-DCM-T2 was augmented with Japanese-specific risk equations to align with the Japanese healthcare context. This study extends prior model validation of IHE-DCM-T2 to cover the Japanese risk equations for applic

Mapping local government priorities : a web-mining approach for regional research

The relevance of institutions for regional development has been well established in economic geography. In this context, local and regional governments play a central role, particularly through place-based and place-sensitive strategies. However, systematic and scalable insights into their priorities and strategies remain limited due to data availability. This paper develops a methodological appro

Development of novel neutralizing single-chain fragment variable antibodies against S100A8

S100A8 plays a critical role in the pathogenesis of several inflammatory diseases and multiple types of cancer. Therefore, targeting the S100A8 function may alleviate the pathogenic process in various diseases. Here, specific single-chain variable fragment (scFv) antibodies targeting recombinant S100A8 (rS100A8) were selected by phage display technique and characterized using cDNA sequencing, immu

Characterization of occupational exposure to air pollutants during asphalt milling and paving

OBJECTIVES: Asphalt is frequently used as road pavement and consists of bitumen as a binder, and fillers. Bitumen consists of a complex mixture of hydrocarbons, where a minor component is polycyclic aromatic hydrocarbons (PAHs). Many PAHs are classified as carcinogenic to humans. Bitumen fumes from road paving have been classified as possibly carcinogenic. Paving and milling are open processes gen

Healthier together. How arts on prescription can promote psychosocial wellbeing : a qualitative study

Background: Mental health problems are an increasing challenge for primary healthcare. It puts strain on the healthcare professionals with limited time and resources. In several countries, healthcare professionals can refer patients with mental health issues to structured arts programmes, namely Arts on Prescription (AoP). This study explores the qualitative findings from a 3-year study on Arts on

Diminished contribution of spring phenology to early-season carbon uptake in a changing climate

Advances in spring phenology (SOS) and increases in terrestrial gross primary productivity (GPP) are well-documented. However, the impact of an earlier SOS on the duration and rate of carbon uptake (GPPrate) during the early growing season (EGS) remains unclear, leaving the overall influence of these factors on EGS GPP uncertain. Using satellite and carbon flux data across the Northern Hemisphere,

Habitat openness and squamate color evolution over deep time

While the ecological roles of colored integument have been extensively studied, what regulates global patterns of color variation remains poorly understood. Here, using a global dataset of 1249 squamates, we evaluate whether and how six key eco-environmental variables and their interactions shaped the evolutionary history of their coloration. We show that only habitat openness consistently associa
