Oxygen physiology and mechanisms of oxygen toxicity: a narrative review

Medical Gas Research
Oxygen inhaled through respiration is consumed in the mitochondria, mainly for oxidative phosphorylation to produce energy. Too little or too much oxygen can be extremely harmful to humans. Insufficient oxygen supply to tissues and organs can result in either dysfunctions or necrosis. However, when the oxygen supply is over supplied,

Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

Advanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

Advanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

Endurance exercise accelerates myocardial tissue oxygenation recovery and reduces ischemia reperfusion injury in mice.

PLoS ONE, 2014
Exercise training offers cardioprotection against ischemia and reperfusion (I/R) injury. However, few essential signals have been identified to underscore the protection from injury.

Three dimensional optical imaging of blood volume and oxygenation in the neonatal brain [PDF]

, 2006
Optical methods provide a means of monitoring cerebral oxygenation in newborn infants at risk of brain injury. A 32-channel optical imaging system has been developed with the aim of reconstructing three-dimensional images of regional blood volume and ...

Remote ischemic preconditioning improves ileal microvascular oxygenation during rodent hemorrhagic shock without improving variables of microcirculation and mitochondrial respiration

Scientific Reports
Hemorrhagic shock is characterized by decreased microvascular blood flow, leading to a critical depletion of tissue oxygenation, particularly within the gastrointestinal tract.

Computed Tomography‐ and Photoacoustic Imaging‐Active Bioresorbable Electrospun Bismuth Nanoparticle‐Infused Small‐Diameter Vascular Grafts

Advanced Healthcare Materials, EarlyView.
A polymeric graft loaded with radiopaque bismuth nanoparticles is expected to undergo gradual polymer resorption and nanoparticle release. This design enables noninvasive, multimodal monitoring of device integrity, patency, and degradation using computed tomography alongside ultrasound and photoacoustic imaging over 12 weeks.

Pressure-adjusted static compression: aerobic metabolism and microvascular perfusion in the context of chemotherapy-induced neuropathy

Cancer & Metabolism
Background Chemotherapy-induced peripheral neuropathy (CIPN) involves impaired microvascular neuronal perfusion and reduced bioenergetics. Compression and cryotherapy are potential preventive measures, yet their mechanism of acral temperature reduction ...
