3D‐Printed Titanium Trabecular Scaffolds with Sustained Release of Hypoxia‐Induced Exosomes for Dual‐Mimetic Bone Regeneration

Advanced Science, EarlyView.
This study presents 3D‐printed Ti‐6Al‐4V trabecular scaffolds combined with hypoxia‐induced exosomes encapsulated in PEGDA/GelMA microspheres for sustained release. The scaffolds mimic the structure of natural bone, while the exosome delivery system enhances osteogenesis and angiogenesis, significantly promoting bone regeneration and offering a ...

The microbiology of deep-sea hydrothermal vent plumes: ecological and biogeographic linkages to seafloor and water column habitats

Frontiers in Microbiology, 2013
Hydrothermal plumes are an important yet understudied component of deep-sea vent microbial ecosystems. The significance of plume microbial processes can be appreciated from three perspectives: (1) mediation of plume biogeochemistry, (2) dispersal of ...

Neutrophil Macrophage Crosstalk via Extracellular Vesicles Drives Reverse Migration in a Fully Human Model of Wound Healing

Advanced Science, EarlyView.
A novel microphysiological system that can mimic sterile or non‐sterile injury demonstrates that macrophage‐derived extracellular vesicles modulate neutrophil migratory responses to these different wound states. The model showed that resolution of inflammation through neutrophil reverse migration is driven by IL‐8 derived from extracellular vesicles ...

Microbiological indicators of water quality

, 2021
The World Health Organization (WHO) recommends the determination of total coliform bacteria and E. Coli in water as the main bacteriological indicators characterizing the quality of drinking water. In a number of CIS countries until now, the main indicator standardized in drinking water is the determination of glucose-positive coliform bacteria and E ...

Suspended Tissue Open Microfluidic Patterning (STOMP)

Advanced Science, EarlyView.
Suspended Tissue Open Microfluidic Patterning (STOMP) is a method that enables precise spatial patterning within a single suspended tissue. By leveraging capillary pinning and open microfluidics, STOMP facilitates the creation of complex tissue interfaces such as diseased‐healthy boundaries and tissue‐tissue junctions. This method integrates mechanical

Microbiological water quality monitoring in a resource-limited urban area: a study in Cameroon, Africa

Journal of Public Health in Africa, 2012
In resource-limited developing nations, such as Cameroon, the expense of modern water-quality monitoring techniques is prohibitive to frequent water testing, as is done in the developed world.

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

Advanced Science, EarlyView.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.
