The Kerguelen Plateau is a biodiversity hotspot with many endemic fish species; furthermore, the region has economic importance in supporting valuable fisheries. This region is also a climate change hotspot with known notable changes in the location of the polar front, ocean currents, and primary productivity. In this study, we use data from long-term scientific trawl surveys and contemporary joint species distribution models to understand how the demersal fish assemblage of the Kerguelen Plateau has changed through time and space. The modelling indicates that most demersal species have had notable changes in their occurrence and CPUE from 2003 to 2016. This included a significant increase in species richness throughout the study period. The modelling also provides novel insights into the depth, climatic, and environmental preferences for all species, including many species that were previously data-limited. It is unclear whether these changes reflect shifts in the fishery management or the effects of climate change, but most likely a combination of all. We also found evidence of several species' distributions responding to temperature variability, with species being exposed to the ongoing impacts of climate change. These findings will be used by managers and policy makers to inform climate change risk assessments, supporting future-decision making to ensure the continuation of sustainable fisheries and the protection of biodiversity.</p>\u0000 </div>","PeriodicalId":175,"journal":{"name":"Global Change Biology","volume":"31 10","pages":""},"PeriodicalIF":12.0,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Automated insulin delivery systems, such as the MiniMed™ 780G (MM780G), offer potential solutions by automating insulin dosing, supporting stable glucose control, and allowing for a higher temporary glucose target. This narrative review summarizes the current evidence on the safety and efficacy of the MM780G system during exercise in PwT1D, with a focus on the temporary target (TT) feature and real-world usability. The MM780G consistently supports glycaemic safety during exercise, especially moderate-intensity aerobic activity, with time in range frequently meeting or exceeding consensus guidelines. Activation of the TT feature 60- to 120-min pre-exercise, particularly when paired with reduced meal boluses, significantly lowers the risk of hypoglycaemia. Real-world studies confirm its safety across varied activities, including prolonged aerobic exercise and contact sports. While evidence for resistance and high-intensity exercise remains limited, initial findings are favourable. User education is crucial to optimize use, particularly in competitive and prolonged settings. The MM780G is a safe and effective tool for glycaemic management during exercise in PwT1D. Best outcomes are achieved through strategic use of the TT feature and meal bolus reduction, individualized carbohydrate strategies and proper education. Applying easy-to-follow pre-exercising recommendations may encourage better engagement with regular exercising. Further research is needed on long-term adaptations to training and resistance-based exercise protocols.</p>","PeriodicalId":158,"journal":{"name":"Diabetes, Obesity & Metabolism","volume":" ","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, how DNA origami design influences folding is investigated using a combination of real-time fluorometry, gel electrophoresis, electron microscopy, and theoretical analysis. Results reveal a balance of free energy changes from loop formation and hybridization that govern nucleation of nanostructure assembly, while the extent of cooperativity determines the overall assembly. The effect of structural complexity, staple design, and scaffold design on each energetic parameter, folding yield, kinetics, and cooperativity is measured. The results show that the scaffold pattern determines the extent of cooperativity, where fewer scaffold crossovers result in more cooperative folding. These findings use a tool developed in this work to estimate the extent of cooperativity in any structure. It is also found that limiting the number of crossovers per staple should be prioritized over extending staple binding domains, as the entropic penalty dominates the favorable binding. Finally, a 1-2 h focused annealing ramp strategy is demonstrated, that can increase yield up to 17% relative to traditional multi-day ramps. Optimizing energy changes and cooperativity through design can significantly enhance assembly yield and reduce time, particularly for complex structures, aiding large-scale DNA materials.</p>","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e04855"},"PeriodicalIF":12.1,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145328031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This simple and efficient preparation method not only reduces the production cost but also improves the manufacturability and performance stability of the sensors, thereby providing important support for the future development of intelligent technologies. The resulting flexible resistive strain sensors exhibit excellent sensing performance, characterized by a maximum strain gauge factor of 9.822, a wide tensile range (<i>ε</i> = 0% to 30%), and commendable cyclic tensile reliability.
