Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu

open access: yesAdvanced Functional Materials, EarlyView.
Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention

The untapped power of a general theory of organismal metabolism [PDF]

open access: yesarXiv
What makes living things special is how they manage matter, energy, and entropy. A general theory of organismal metabolism should therefore be quantified in these three currencies while capturing the unique way they flow between individuals and their environments. We argue that such a theory has quietly arrived -- 'Dynamic Energy Budget' (DEB) theory --

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Purification and characterization of a tyrosinase inhibitor from camellia pollen

open access: yesJournal of Functional Foods, 2016
Bee pollen is an important bee-product that contains larger amount of bioactive compounds. In this paper, a tyrosinase inhibitor was separated from camellia pollen by the aid of high-speed counter-current chromatography (HSCCC), macroporous adsorptive ...
