The role of the gut microbiome in the regulation of high‐altitude adaptation

open access: yesiMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...

Mimicking DOUGONG brackets orchestrate regulating inflammation and mechanical stimuli for osteochondral regeneration using 3D printing

open access: yesInterdisciplinary Medicine, EarlyView.
Akermanite scaffolds promote osteogenic differentiation of BMSCs through regulating the PI3K/Akt signaling pathway, and strontium ions enhance the akermanite effects by mediating the cytokine‐cytokine receptor interaction pathway. Thus, the enhancements of osteogenesis in subchondral bone coupled with the chondral‐promoting effects of chondrocytes ...

Cell Toxicity and Autophagy in A549 Cells Treated With Surface‐Functionalized Graphene Derivatives

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Graphene oxide and its derivatives have unique physical and chemical properties with applications in many different fields. However, their biological effects and mechanisms of intracellular toxicity have not been completely clarified. In this study, we investigated the cytotoxic and autophagic activities of graphene oxide and its derivatives ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...
