Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics

Advanced Functional Materials, EarlyView.
Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Understanding the Effects of Conductive Polymer Electrode Coating on Recorded Neural Signals

Advanced Healthcare Materials, EarlyView.
Conductive polymer coatings are widely explored to improve the quality of signals recorded with chronically implanted neural electrodes, offering enhanced biocompatibility along with reduced electrode impedance. Combining computational modelling and data from PEDOT:PTS coated and PtIr electrodes in rats, we show that improvements in signal quality with

Spin-Mediated Consciousness Theory: An Approach Based On Pan-Protopsychism [PDF]

, 2002
As an alternative to our original dualistic approach, we present here our spin-mediated consciousness theory based on pan-protopsychism. We postulate that consciousness is intrinsically connected to quantum mechanical spin since said spin is embedded in ...

Coacervates Made of Elastin‐Like Polypeptides Fused with Melanocyte‐Stimulating Hormone and Monocyte Chemoattractant Protein Enhance Skin Wound Healing in Spinal Cord‐Injured Mice

Advanced Healthcare Materials, EarlyView.
Pressure skin wounds are frequent complications after spinal cord injury (SCI), with impaired healing due to vascular and immune deficits. Elastin‐like polypeptides (ELP) fused to α‐MSH (MSH‐ELP) or MCP‐1 (MCP‐ELP) are developed and tested on these wounds. The resulting nanoparticles are non‐toxic and bioactive, and they enhance macrophage recruitment,

A Simple, Inexpensive, and Effective Light- Carrying Laryngoscopic Blade for Orotracheal Intubation of Rats [PDF]

, 2006
The research paradigm of using large laboratory animals, in which oroendotracheal intubations are relatively easy, is shifting toward the use of small animals, such as rodents, in which oropharyngeal access is limited, the arytenoid cartilage cycles are ...
