Action potential as a pressure pulse propagating in the axoplasm [PDF]

arXiv, 2009
We suggest that the propagation of the action potential is driven by a pressure pulse propagating in the axoplasm along the axon length. The pressure pulse mechanically activates Na ion channels embedded in the axon membrane. This activation initiates the development of a local membrane voltage spike, as in the Hodgkin-Huxley model of the action ...

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

Information capacity and transmission are maximized in balanced cortical networks with neuronal avalanches [PDF]

The Journal of Neuroscience, January 5, 2011 31(01), 2010
The repertoire of neural activity patterns that a cortical network can produce constrains the network's ability to transfer and process information. Here, we measured activity patterns obtained from multi-site local field potential (LFP) recordings in cortex cultures, urethane anesthetized rats, and awake macaque monkeys.

Bioprinting Perfusable and Vascularized Skeletal Muscle Flaps for the Treatment of Volumetric Muscle Loss

Advanced Healthcare Materials, EarlyView.
Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Lycium‐Barbarum Polysaccharide‐Loaded Dual‐Crosslinked Rigid Hydrogel Enhances Bone Healing in Diabetic Bone Defects by Scavenging Reactive Oxygen Species

Advanced Healthcare Materials, EarlyView.
A novel hydrogel (HLBP) incorporating natural polysaccharides from goji berries is developed to enhance diabetic bone defect healing. The hydrogel efficiently scavenges ROS, improves osteogenic differentiation, and promotes in vivo bone regeneration. This strategy offers a biocompatible and localized approach, overcoming the challenges of traditional ...

Mechanism of Anesthetic Action: Oxygen Pathway Perturbation Hypothesis [PDF]

Medical Hypothese (2001) 57(5): 619-627., 2001
Although more than 150 years have past since the discovery of general anesthetics, how they precisely work remains a mystery. We propose a novel unitary mechanism of general anesthesia verifiable by experiments. In the proposed mechanism, general anesthetics perturb oxygen pathways in both membranes and oxygen-utilizing proteins such that the ...
