Characterization of the R893C NaV1.5 mutation in Brugada syndrome

Frontiers in Cardiovascular Medicine
Brugada syndrome (BrS) is a genetically determined cardiac arrhythmogenic syndrome with increased risk of sudden cardiac death. BrS is mostly caused by mutations in SCN5A gene encoding the primary ɑ-subunit of the cardiac sodium channel NaV1.5.

In-flight Monitoring of TerraSAR-X Radar Instrument Stability [PDF]

, 2007
For calibrating and monitoring the radiometric stability, the radar instrument of TerraSAR-X hosts a passive calibration network coupling into an additional port of the T/R modules. Three different types of calibration pulses are applied, whereby sets of

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Adipocyte ABCA1 expression analysis using flow cytometry

BioTechniques
Adipocyte characterization and assessing membrane proteins using flow cytometry has been proven to be challenging as adipocytes are fragile, especially in subjects with high BMI. We overcame these challenges through a protocol optimizing tissue digestion

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Real-time tracking of lung tumors using a 1.5T Elekta Unity MR-Linac: first clinical experiences

Frontiers in Oncology
There is a growing interest in the application of MRI-guided adaptive radiotherapy (MRIgART) to improve the treatment of lung tumors. Motion management plays a central role to better localize these tumors and minimize toxicities to surrounding healthy ...

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

The C-terminus of the multi-drug efflux pump EmrE prevents proton leak by gating transport

eLife
The model multi-drug efflux pump from Escherichia coli, EmrE, can perform multiple types of transport leading to different biological outcomes, conferring resistance to some drug substrates and enhancing susceptibility to others.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed
