The two main glial cell types of the central nervous system (CNS), astrocytes and microglia, are responsible for neuroimmune homeostasis. Recent evidence indicates astrocytes can participate in removal of pathological structures by becoming phagocytic under conditions of neurodegenerative disease when microglia, the professional phagocytes, are impaired. We hypothesized that adenosine triphosphate (ATP), which acts as damage-associated molecular pattern (DAMP), when released at high concentrations into extracellular space, upregulates phagocytic activity of human astrocytes.

Interventions for adult congenital heart disease.

Nat Rev Cardiol

January 2025

Quebec Heart & Lung Institute, Laval University, Quebec City, Quebec, Canada.

Advances in imaging diagnostics, surgical techniques and transcatheter interventions for paediatric patients with severe congenital heart disease (CHD) have substantially reduced mortality, thereby extending the lifespan of these individuals and increasing the number of adults with complex CHD. Transcatheter interventions have emerged as an alternative to traditional open-heart surgery to mitigate congenital defects. The evolution of techniques, the introduction of new devices and the growing experience of operators have enabled the treatment of patients with progressively more complex conditions.

Historically, Aboriginal and Torres Strait Islander research in Australia has adhered to Western research paradigms and contributed to the adverse impacts of colonisation. However, recent developments driven by Aboriginal and Torres Strait Islander people and scholars, and development of ethical guidelines for research, have promoted a more inclusive and collaborative research landscape. In this study, published papers and internal documents arising from a long-term partnership between Marninwarntikura Women's Resource Centre (MWRC) and the University of Sydney (USYD) from 2009 to 2023 were analysed using the Aboriginal and Torres Strait Islander Quality Appraisal Tool and consultations with project partners.

Kinship clustering within an ecologically diverse killer whale metapopulation.

Heredity (Edinb)

January 2025

Centre for Ecological and Evolutionary Synthesis, Department of Biosciences, University of Oslo, Oslo, Norway.

Metapopulation dynamics can be shaped by foraging ecology, and thus be sensitive to shifts in prey availability. Genotyping 204 North Atlantic killer whales at 1346 loci, we investigated whether spatio-temporal population structuring is linked to prey type and distribution. Using population-based methods (reflecting evolutionary means), we report a widespread metapopulation connected across ecological groups based upon nuclear genome SNPs, yet spatial structuring based upon mitogenome haplotypes.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Electrophysiological approaches to informing therapeutic interventions with deep brain stimulation.

NPJ Parkinsons Dis

January 2025

Neural Engineering with Signal Analytics and Artificial Intelligence, Department of Neurology, University Clinic Würzburg, Würzburg, Germany.

Neuromodulation therapy comprises a range of non-destructive and adjustable methods for modulating neural activity using electrical stimulations, chemical agents, or mechanical interventions. Here, we discuss how electrophysiological brain recording and imaging at multiple scales, from cells to large-scale brain networks, contribute to defining the target location and stimulation parameters of neuromodulation, with an emphasis on deep brain stimulation (DBS).

The latest climate models project widely varying magnitudes of future extreme precipitation changes, thus impeding effective adaptation planning. Many observational constraints have been proposed to reduce the uncertainty of these projections at global to sub-continental scales, but adaptation generally requires detailed, local scale information. Here, we present a temperature-based adaptative emergent constraint strategy combined with data aggregation that reduces the error variance of projected end-of-century changes in annual extremes of daily precipitation under a high emissions scenario by >20% across most areas of the world.

Sleeve gastrectomy reveals the plasticity of the human gastric epithelium.

Nat Commun

January 2025

Department of Developmental Biology and Cancer Research, The Institute for Medical Research Israel Canada, The Faculty of Medicine, The Hebrew University of Jerusalem, Jerusalem, Israel.

Gastrin is secreted following a rise in gastric pH, leading to gastric acid secretion. Sleeve gastrectomy (SG), a bariatric surgery where 80% of the gastric corpus is excised, presents a challenge for gastric pH homeostasis. Using histology, and single-cell RNA sequencing of the gastric epithelium in 12 women, we observed that SG is associated with an increase in a sub-population of acid-secreting parietal cells that overexpress respiratory enzymes and an increase in histamine-secreting enterochromaffin-like cells (ECLs).

Introduction: Considering the impact of non-medical factors (personal and social) on patients with multiple chronic conditions, the term 'medical complexity' is gaining traction as it encompasses both medical and non-medical aspects of patients' medical needs. When primary care is not able to provide timely care for chronic challenges or acute concerns, complex patients require care in emergency or urgent care settings. The concept of medical complexity is continually evolving, although without a universally accepted or standardised definition that determines if an adult patient is considered complex.

Introduction: While principles of neuroplasticity and motor learning emphasise the potential of high dosage of physical rehabilitation in children and adolescents with acquired brain injury (ABI) during the subacute phase, we lack empirical evidence to demonstrate its impact in terms of meaningful outcomes. Clinical research is needed to investigate adequate dosage of physical rehabilitation and its effects on outcomes with reliable and validated outcome measurements. In this study we will investigate the feasibility of a highly intensive physical rehabilitation intervention and outcomes with reliable and valid outcome measurements.
