Background: Growing evidence suggests that pesticide exposure may influence respiratory health, but data in young children are very limited. We examined the association of prenatal pesticide exposure with lower respiratory tract infections (LRTIs) and wheeze at one year of age in children from the Infants' Environmental Health (ISA) study in Costa Rica. Methods: We measured seven pesticide metabol
Introduction: Dystonia-deafness syndrome is a distinct clinical presentation within the dystonia-spectrum. Although several genetic and acquired causes have been reported, etiology remains unknown in the majority of patients. Objectives: To describe two patients with dystonia-deafness syndrome due to a beta-actin gene mutation. Methods: We report on disease course, genetic testing, and management
In this paper, we describe a distinct clinical subtype of 3-methylglutaconic aciduria. 3-Methylglutaconic aciduria is a group of different metabolic disorders biochemically characterized by increased urinary excretion of 3-methylglutaconic acid. We performed biochemical and genetic investigations, including urine organic acid analysis, NMR spectroscopy, measurement of 3-methylglutaconyl-CoA hydrat
Joint Species Distribution Modelling (JSDM) is becoming an increasingly popular statistical method for analysing data in community ecology. Hierarchical Modelling of Species Communities (HMSC) is a general and flexible framework for fitting JSDMs. HMSC allows the integration of community ecology data with data on environmental covariates, species traits, phylogenetic relationships and the spatio-t
Using high-resolution extreme ultraviolet resonant inelastic x-ray scattering (EUVRIXS) spectroscopy at the Cu M-edge, we observed doping dependent spectral shifts of interorbital (dd) excitations of YBa2Cu3O7-y and La2-xSrxCuO4. With increasing the hole doping level from undoped to optimally doped superconducting compositions, the leading edge of dd excitations is found to shift towards lower ene
In 1825, an unnamed Stellenbosch official paused his tax collection duties to pen a poem in the margins of the opgaafrol. His verses capture the frustrations of colonial administration but the records themselves–annual tax censuses spanning 1685 to 1844–offer a far richer window into the Cape Colony’s social and economic history. First established by the Dutch East India Company and later maintain
Understanding the interplay between human brain structure and function is crucial to discern neural dynamics. This study explores the relation between brain structure and macroscale functional activity using subject-specific structural connectome eigenmodes, complementing prior work that focused on group-level models and geometry. Leveraging data from the Human Connectome Project, we assess accura
Differences between men and women in cognitive impairment and neurodegeneration are not yet well understood. Although sex differences in brain structure abnormalities, including white matter hyperintensities (WMH) and grey matter (GM) atrophy, have been associated with cognitive decline in the ageing population, the evidence is limited and inconclusive. Therefore, we explored sex differences in br
LONG-TERM depletion of ozone has been observed since the early 1980s in the Antarctic polar vortex, and more recently at mid-latitudes in both hemispheres, with most of the ozone loss occurring in the lower stratosphere1. Insufficient measurements of ozone exist, however, to determine decadal trends in ozone concentration in the Arctic winter. Several studies of ozone concentrations in the Arctic
Study region: The Paranapanema River Basin, located in southeastern Brazil, is characterized by a cascade of large hydropower plants regulated by a nationally coordinated dispatch system. This basin is a representative case of reservoir-regulated rivers in the country, where multiple dams interact to supply electricity while reshaping natural flow regimes. Study focus: This study examines hydropow
Our relationships with others structure many aspects of our lives, especially during important moments such as choosing an education, entering the workforce, forming partnerships or starting a family. While the influence of family and parenting has been widely studied, less is known about the role of non-family connections, such as neighbours. One reason is that the data needed to study these rela
Medical, neurological, and substance use disorders constitute a major disease burden worldwide, but especially in low- and middle-income countries (LMICs) where more than 80% of affected persons are unable to receive evidence-supported treatments despite these being widely available in theory. This persistent mental health treatment gap in LMICs is traceable to the very nature of such nations: low
Partial-volume effects (PVEs) arise from the limited spatial resolution of PET and SPECT imaging systems, causing the systematic underestimation of activity concentration in structures that may hold critical diagnostic, treatment, or dosimetric information that impacts patient management. Recovery coefficient (RC)-based partial-volume correction (PVC) is one of the simpler approaches used to corre
Many animals undergo irreversible ontogenetic color changes (OCCs), yet these changes are often overlooked despite their potential ethological relevance. The problem is compounded when OCCs involve wavelengths invisible to humans. Wall lizards can perceive ultraviolet (UV) light, and their conspicuous ventral and ventrolateral coloration—including UV-reflecting patched—likely serves social communi
Objective: The objective of this study was to compare health-related quality of life (HRQoL) and work productivity in axial SpA (axSpA) and non-axSpA patients with chronic back pain of <2 years. Methods: Baseline and 2-year data for patients included in the SPondyloArthritis Caught Early cohort were analysed. HRQoL was assessed by the physical (PCS) and mental component summary (MCS) scores of the
Sodium ion batteries have been considered as promising alternatives to lithium ion batteries for large-scale renewable energy and smart grids applications due to their low cost and rich resources. However, critical drawbacks such as low energy density and poor stability are hindering their development and application. In this work, a stable symmetric sodium ion cell using sodium vanadium pyrophosp
The Sulu Archipelago, nestled between Mindanao and Borneo, has been a melting pot of people and cultures for thousands of years. Major sociopolitical changes marked its history, attracting groups of people or forcing drastic dispersals. Today, the islands host various ethnolinguistic groups, including Sama-Badjaw and Tausug-speaking communities. We surveyed the literature from multiple disciplines
