An Integrated Approach to Determining the Risk of Overexploitation for Data-Poor Pelagic Atlantic Sharks [PDF]

open access: yes, 2008
Assesses the risk of over-exploitation of sharks in Atlantic longline fisheries using three metrics based on multivariate statistics as a way to make management recommendations for species with limited data.

Bioinspired Claw‐Engaged Adhesive Microparticles Armed with γGC Alleviate Ulcerative Colitis via Targeted Suppression of Macrophage Ferroptosis

open access: yesAdvanced Science, EarlyView.
γGC deficiency in ulcerative colitis drives macrophage ferroptosis‐mediated inflammation. Claw‐engaged microparticles armed with γGC (γGC‐MPs) enhance lesion targeting, promoting localized γGC release and tissue uptake. On the cover, Monkey King (Macrophages) was bound by the Immortal‐Binding Rope and subsequently sealed beneath the Five‐Fingered ...

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

open access: yesAdvanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

When can few-species models describe dynamics within a complex community? [PDF]

open access: yesarXiv
Dynamics of species' abundances in ecological communities are often described using models that only account for a few species. It is not clear when and why this would be possible, as most species form part of diverse ecological communities, with many species that are not included in these few-variable descriptions.

Ultrasound‐Assisted for Super‐Rapid and High‐Efficient Adsorption and Desorption

open access: yesAdvanced Science, EarlyView.
Adsorption–desorption technologies face challenges due to slow adsorption and complex regeneration. This study shows that PVDF‐HFP offers exceptional adsorption kinetics and regeneration efficiency under ultrasound, adsorbs Rhodamine B 23,000 times faster than activated carbon, removing 90% of levofloxacin and PFOA in 5 min, and maintains performance ...
