Circulating succinate changes during acute cold exposure are not related with brown adipose tissue in humansNARA Subscribed
Brown adipose tissue (BAT) activity in humans is linked to better glucose metabolism and cardiometabolic health. In mice, cold exposure increases circulating succinate and enhances BAT thermogenesis, but whether similar succinate responses occur in humans remains undetermined. We analysed data from 33 young (18–25 years), sedentary adults (20 women) from the ACTIBATE cohort (NCT02365129). Plasma succinate was measured enzymati...
Cold exposure activates brown adipose tissue (BAT), a therapeutic target to mitigate cardiometabolic diseases. Emerging evidence suggests that bile acids may influence BAT activity through metabolic and endocrine signaling pathways. Characterizing changes in circulating bile acids during cold exposure may uncover new pathways to improve metabolic health in humans. We analysed 56 young (21.7 ± 2.3 years old), sedentary adults (...
Liver fibrosis and type 2 diabetes modulate postprandial incretin and glucagon responses in fatty liver diseaseNARA Subscribed
The study aims to characterize the secretion dynamics of glucagon-related peptides, including GLP-1, GIP, and GLP-2, across different stages of metabolic-associated steatotic liver disease (MASLD), while evaluating the impact of type 2 diabetes (T2D) on these hormonal responses. Thirty-four MASLD subjects were stratified according with the liver transient elastography (TE ≥ 9 kPa) and T2D in NF (no fibrosis, without T2D; n = 1...
Myocardial infarction (MI) remains a leading cause of heart failure, and current therapies fail to prevent cardiomyocyte loss or support effective tissue regeneration. Injectable hydrogels (HGs) have emerged as promising platforms for delivering therapeutic cues and structural support; however, few systems simultaneously integrate vascular guidance and RNA therapeutics. Here, we have developed a thermosensitive alginate-collag...
Consistent topsoil carbon density and driving factors in urban greenspaces and natural ecosystemsNARA Subscribed
Background Urban greenspaces have the potential to mitigate urban carbon footprints by storing soil organic carbon (SOC). Different management and plant communities associated with different types of urban greenspaces may hold contrasting SOC, as well as different proportions of particulate (POC) and mineral-associated organic carbon (MAOC). In addition, management could outweigh the effects of climate or soil properties as dr...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Ecological Niche Differences Underlie the Assembly of Endemic Birds in Acrobiont Forests of Northern MesoamericaNARA Subscribed
Aim The study of the structure of species assemblages has typically assumed that similar environments share common species; however, interacting biogeographic and phylogenetic processes are equally important. The understanding that ecological processes operate at different spatial scales to shape species assemblages led to the concept of metacommunity, bridging studies from large (distributional patterns) to smaller scales (sy...
Effects of simulated climate change on soil characteristics under Carpobrotus edulis invasion in a coastal backduneNARA Subscribed
Background and aims Along coastal habitats worldwide, Carpobrotus edulis is a highly invasive and detrimental species, that acts as an ecosystem engineer by modifying many soil properties for its own benefit. However, the combined effects of C. edulis and climate change on soil characteristics remain largely unknown. Methods To address this knowledge gap, we set up a factorial field experiment with five treatments and eight re...
