Cerium oxide nanoparticles with antioxidative neurorestoration for ischemic stroke
Biomaterials. 2022 Nov 10;291:121904. doi: 10.1016/j.biomaterials.2022.121904. Online ahead of print.ABSTRACTOxidative stress and mitochondrial damage are the main mechanisms of ischemia-reperfusion injury in ischemic stroke. Herein, cerium oxide nanoparticles with powerful free radical scavenging ability were used as carriers to load dl-3-n-butylphthalide (NBP-CeO2 NPs) for the combined treatment of ischemic stroke. NBP-CeO2 NPs could eliminate reactive oxygen species (ROS) in mouse brain microvascular endothelial cells and hippocampal neurons after oxygen-glucose deprivation/reoxygenation (OGD/R), and also save mitochond...

Genetically encoded FRET-based biosensor for imaging MMP-9 activity.
Abstract A genetically encoded Förster Resonance Energy Transfer (FRET)-based biosensor that continuously monitors matrix metalloproteinase 9 (MMP-9) activity was developed. MMP-9 is an extracellularly acting endopeptidase with a prominent role in development, learning and memory, cancer metastasis, and stroke. To assess the biological function of the protease, determining the precise kinetics and localization of MMP-9 activity is required. The nontoxic, genetically encoded FRET biosensor presented herein is anchored in the cellular membrane and thus provides an important advantage over currently employed probes....

(376) Impact of the Harborview Chronic Pain Self-Management Program on participants ’ quality of life, confidence and pain experience
The Chronic Pain Self-Management Program (CPSMP) is as an evidenced-based model that helps sufferers of chronic pain conditions learn how to better manage their pain symptoms and overall health status. The CPSMP involves a six-week long workshop that is designed for adults with chronic pain conditions to work together and build off of each other ’s strengths and knowledge regarding pain management. The program is adapted from the well-researched Chronic Disease Self-Management Program developed at Stanford that followed more than 1000 people with heart disease, lung disease, stroke or arthritis in a three-year randomized...

Multicomponent material property characterization of atherosclerotic human carotid arteries through a Bayesian Optimization based inverse finite element approach
CONCLUSION: The developed iFEM approach combined with the inverted GP model successfully predicted component-wise material properties of intact atherosclerotic human carotids ex-vivo under physiological-like loading conditions.SIGNIFICANCE: We developed a novel iFEM framework for the nonlinear, component-wise material characterization of atherosclerotic arteries and utilized it to obtain human atherosclerotic carotid material properties. The developed iFEM framework has great potential to be advanced for patient-specific in-vivo application.PMID:34864574 | DOI:10.1016/j.jmbbm.2021.104996
