Poly(hydroxy‐oxazolidone) Thermoplastic Elastomers for Safer, Greener and Customizable Blood‐Contacting Medical Devices

open access: yesAdvanced Healthcare Materials, EarlyView.
A poly(hydroxy‐oxazolidone) (PHOx) is synthesized from CO2‐based precursors, enabling the up‐cycling of this waste material. After synthesis, PHOx shows thermoplastic properties, and can therefore be processed by many temperature‐dependent techniques. PHOx is hemocompatible, anti‐adhesive, and biocompatible, which is demonstrated in vitro and in vivo ...

Hub-organized parallel circuits of central circadian pacemaker neurons for visual photoentrainment in Drosophila

open access: yesNature Communications, 2018
Circadian rhythms are orchestrated by a master clock that emerges from a network of circadian pacemaker neurons. The master clock is synchronized to external light/dark cycles through photoentrainment, but the circuit mechanisms underlying visual ...

Metal–Organic Framework‐Based Antimicrobial Touch Surfaces to Prevent Cross‐Contamination

open access: yesAdvanced Materials, EarlyView.
A MOF‐based antimicrobial door handle cover is developed. It completely inhibits the cross‐contamination of Gram‐positive bacterial species (Staphylococcus aureus, and Enterococcus faecalis), Gram‐negative bacterial species (Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii), and fungi (Candida albicans). Abstract Infection diseases

Syncope as a presenting feature of complete extrusion of a unipolar permanent pacemaker

open access: yesCHRISMED Journal of Health and Research, 2016
Complete extrusion of a permanent pacemaker is an extremely rare complication. We report a unique case of a patient presenting with syncopal episodes after complete extrusion of his implanted pacemaker.

Two cases of hemodynamic improvement by modulation of atrioventricular delay in cardiac operations

open access: yesJA Clinical Reports, 2022
Background Symptomatic sick sinus syndrome is one of the indications for pacemaker implantation, and we have to consider to program the pacemaker to an asynchronous pacing mode during an operation. Case presentation We reported two cases with a pacemaker

Stimuli‐Responsive Materials for Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
Stimulus‐responsive materials (SRMs) hold great promise for use in a wide range of biomedical applications. This review covers four stimulus modalities, namely, electrical, optical, magnetic, and ultrasound, and their associated SRMs. It provides a summary of the materials in each modality, their development, and current research perspectives.

3D Printing of Conducting Polymer Hydrogels for Electrostimulation‐Assisted Tissue Engineering

open access: yesAdvanced Materials, EarlyView.
This review highlights nanosized inherently conducting polymers (ICPs) as promising ink constituents for 3D printing of conducting hydrogel (CH)‐based electrostimulation (ES) devices. ICP‐based ink formulation, 3D printing, and solidification strategies are discussed, along with the application of 3D‐printed ICP‐based CHs as ES platforms for regulating
