Biopolymer‐Templated Hierarchical 3D‐Structured Gold Nanoparticle/Graphene Oxide Hybrid Materials for Ultrasensitive Surface‐Enhanced Raman Scattering

Advanced Functional Materials, EarlyView.
A scalable bio‐templated approach using spray‐coating and thermal annealing fabricates cellulose nanofibril (CNF) films loaded with gold nanoparticles (Au NPs) and graphene oxide (GO) hybrids as Surface‐enhanced Raman scattering (SERS) substrates. The 3D CNF network ensures uniform Au NPs distribution, while annealing induces more hotspots, confirmed ...

Osborn Waves: History and Significance [PDF]

, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...

Local Anaesthesia Suppressing Idiopathic Ventricular Tachycardia - A Cause of Non-inducible Arrhythmia During Electrophysiology Study [PDF]

, 2011
A 13year old boy having idiopathic ventricular tachycardia had non-inducible tachycardia twice on electrophysiology (EP) study due to suppression of arrhythmia by local anaesthetic agent, lignocaine.

Novel Bioconjugate Materials: Synthesis, Characterization and Medical Applications

Advanced Healthcare Materials, EarlyView.
This review discusses the bioconjugation of novel materials grouped under “biological”, “hybrid” and “synthetic” categories. Medical applications ranging from cancer therapy and diagnostics to optogenetics and tissue engineering are explored, and conjugation trends are highlighted as a general guide. The review concludes with a comparison of techniques

Cardiac resynchronization therapy with His bundle pacing

Pacing and Clinical Electrophysiology, 2019
AbstractAimsA novel therapy offering cardiac resynchronization therapy (CRT) with an additional lead placed in His bundle has been reported in a few case reports and case series as improving the hemodynamical and clinical condition of patients with permanent atrial fibrillation (AF) in whom other therapeutic methods have not been successful ...

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

Advanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Peri‐left bundle branch pacing after atrioventricular node ablation and failed his bundle pacing in atrial fibrillation

Journal of Arrhythmia, 2020
We described a case where peri‐left bundle branch pacing (PLBP) may become an alternative approach in difficult His bundle pacing (HBP) following atrioventricular nodal ablation in a patient with atrial fibrillation. After atrioventricular nodal ablation,

Mapping and Ablating Ventricular Premature Contractions That Trigger Ventricular Fibrillation: Trigger Elimination and Substrate Modification [PDF]

, 2014
Ventricular fibrillation (VF) is a malignant arrhythmia, usually initiated by a ventricular premature contraction (VPC) during the vulnerable period of cardiac repolarization. Ablation therapy for VF has been described and increasingly reported.
