Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Measuring and understanding biogenic influences upon cohesive sediment stability in intertidal systems [PDF]

open access: yes, 2010
Intertidal cohesive sediment systems are found throughout the world in areas of low hydrodynamic energy. These systems are ecologically and economically important but are under pressure from global warming, sea level rise and other anthropogenic ...

Variation in Fluorescence in Some Northeast Atlantic Malacostraca (Pancrustacea)

open access: yesDiversity
Fluorescence is known to occur on varying surfaces across crustacea but is only cited in sporadic reports, despite being a potentially important visual signal and changing with development and within moult cycles.

Effects of typical artificial reefs on hydrodynamic characteristics and carbon sequestration potential in the offshore of Juehua Island, Bohai Sea

open access: yesFrontiers in Environmental Science, 2022
The ocean system provides abundant food resources and suitable habitats for numerous animal and plant species. However, the ecological health of the ocean system has deteriorated due to intensified human activities over the past decades.

River sediments [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Abstract River history is reflected in the nature of the sediments carried and deposited over time. Using examples drawn from around the world, this account illustrates how river sediments have been used to reconstruct past environmental changes at a variety of scales in time and space.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Measurement of spatial and temporal fine sediment dynamics in a small river [PDF]

open access: yes, 2012
Empirical measurements on fine sediment dynamics and fine sediment infiltration and accumulation have been conducted worldwide, but it is difficult to compare the results because the applied methods differ widely.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Hybrid bioelectrochemical process enables hierarchical C, N, and P utilization towards negative carbon emission wastewater treatment

open access: yesNature Communications
Bioelectrochemical system (BES) can provide sustainable solutions for wastewater treatment through lower energy consumption, reduced carbon emissions, and nutrient capture and reuse.

Sedimentation of Reservoirs [PDF]

open access: yes, 2013
S waves are seismic body waves meaning they travel through the Earth's interior. Their velocity is slower thant that of P waves, and they are normally the second major phase to be observed on a seismorgram, and are therefore also referred to as secondary waves.
