Mining revival [PDF]

open access: yes, 2010
In relation to its size the United Kingdom (UK) is remarkably well-endowed with mineral resources as a result of its complex geological history. Their extraction and use have played an important role in the development of the UK economy over many years ...

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Analysis of the spatiotemporal evolution and driving factors of land use change in Jinan springs area of the Northern Karst region, China from 1986 to 2022

open access: yesDiscover Applied Sciences
The Jinan Spring Area serves as a representative of northern China’s karst regions. To explore the land-use change characteristics and their driving mechanisms, six periods of Landsat series land-use data were collected for the years 1986, 1995, 2000 ...

Start, Stop, Rewind, Repeat—Cyclic Exposure of Adipose Stromal Cells‐derived Cartilage Organoids to Chondrogenic and Proliferative Cues to Achieve Scaled‐up and Customizable Bone Formation by Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
This study exploits the plasticity of ASCs‐derived cartilage organoids which generate a perichondrial layer of MSCs when exposed to cyclic chondrogenic/proliferative cues. Using these organoids as building blocks, we develop (i) Phalange Shaped Tissue Engineered Cartilage (Pa‐TECs), recapitulating endochondral ossification suitable for the treatment of

Earth resources evaluation for New Mexico by LANDSAT-2 [PDF]

open access: yes
The author has identified the following significant results. The Middle Rio Grande project has not yet progressed to the point where mineral exploration sites can be chosen; however, there does appear to be some correlation between the known structure ...

Zinc‐Containing Bioactive Glass Programs Macrophage Polarization through Extracellular Traps Regulation for Enhanced Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Zinc‐containing bioactive glass (ZnBG) promotes diabetic wound healing by regulating macrophage extracellular traps (METs). Specifically, ZnBG reduces oxidative stress and inhibits the PAD4 and NLRP3/caspase‐1/GSDMD signaling pathways, thereby suppressing MET formation.
