Multifunctional Manganese Oxide Nanocomposite Hydrogel With Synergistic Reactive Oxygen Species‐Scavenging, Oxygen‐Generating, Immunomodulatory, and Photothermal Antimicrobial Activities for Enhanced Diabetic Wound Healing

Advanced Science, EarlyView.
CFP/PC@MnO2 hydrogel integrates ROS scavenging, oxygen delivery, oxidative stress reduction, immunomodulation, and photothermal antibacterial properties. The incorporation of PC@MnO2 NPs endows the hydrogel with multiple functional advantages tailored to the pathological microenvironment of diabetic wounds, including efficient ROS clearance, mitigation

Assessment of Density Variations of Marine Sediments with Ocean and Sediment Depths

The Scientific World Journal, 2014
We analyze the density distribution of marine sediments using density samples taken from 716 drill sites of the Deep Sea Drilling Project (DSDP). The samples taken within the upper stratigraphic layer exhibit a prevailing trend of the decreasing density ...

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Distribution of eukaryotic environmental DNA in global subseafloor sediments

Progress in Earth and Planetary Science
The analysis of eukaryotic environmental DNA (eDNA) in sediment has the potential for understanding past ecosystems, even for taxa lacking skeletons or preserved only as a part of necromass.

CH4–C3H8 mixed gas hydrate behavior in natural marine sediments: influence of sediment type and dissociation pathways

Frontiers in Marine Science
The dissociation behavior of CH4–C3H8 mixed gas hydrates in natural marine sediments is critical to global carbon storage and marine biogeochemical cycles, but the effects of sediment composition and dissociation pathways remain unclear.

AI Designed Conformation Locking Peptides Target STING to Restore Diabetic Wound Healing

Advanced Science, EarlyView.
A generative AI pipeline identifies SCP‐1, a conformation‐locking peptide that stabilizes inactive STING. Incorporated into a dual‐responsive hydrogel for localized, MMP‐9‐triggered release, SCP‐1 suppresses inflammation, promotes reparative macrophage polarization, and accelerates diabetic wound healing.

Unveiling the Taxonomic Diversity and Unprecedented Biosynthetic Treasure of the Phylum Myxococcota

Advanced Science, EarlyView.
Natural products remain vital sources of therapeutics, and the phylum Myxococcota constitutes an especially rich reservoir for them. Based on decades of microbiological efforts, we present 154 new Myxococcota genomes and revise taxonomy quadrupling the number of families and genera.

Adsorption Behaviour Characteristics of Phosphorus in Core Sediments from the Main Estuaries of the Maowei Sea

Progress in Fishery Sciences
In recent decades, eutrophication, harmful algal blooms, and seasonal hypoxia in the bottom water have been frequently reported in Chinese coastal waters owing to excessive human-induced nutrient input. Phosphorus (P) is an essential biogenic element for

SEDIMENTARY FEATURES OF TSUNAMI BACKWASH DEPOSITS AS ASSESSED BY MICRO-BEAM SYNCHROTRON X-RAY FLUORESCENCE (μ-SXRF) AT THE SIAM PHOTON LABORATORY [PDF]

Science of Tsunami Hazards, 2013
Over the past few years, several attempts have been performed to find alternative “chemical proxies” in order to discriminate “tsunami backwash deposits” from “typical marine sediments”.
