Millimetre-scale magnetocardiography of living rats using a solid-state quantum sensor [PDF]

arXiv, 2021
A key challenge in cardiology is the non-invasive imaging of electric current propagation occurring in the cardiovascular system at an intra-cardiac scale. A promising approach for directly mapping the current dynamics is to monitor the associated stray magnetic field.

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Estimation of fibre architecture and scar in myocardial tissue using electrograms: an in-silico study [PDF]

arXiv, 2022
Atrial Fibrillation (AF) is characterized by disorganised electrical activity in the atria and is known to be sustained by the presence of regions of fibrosis (scars) or functional cellular remodeling, both of which may lead to areas of slow conduction.

HL-1 cells express an inwardly rectifying K+ current activated via muscarinic receptors comparable to that in mouse atrial myocytes [PDF]

, 2010
An inwardly rectifying K^+ current is present in atrial cardiac myocytes that is activated by acetylcholine (I_{KACh}). Physiologically, activation of the current in the SA node is important in slowing the heart rate with increased parasympathetic tone ...

Non‐Invasive Diagnosis of Hypertrophic Cardiomyopathy by Breath

Advanced Sensor Research, EarlyView.
The use of sensor technologies for the diagnosis of hypertrophic cardiomyopathy (HCM) by identification of volatile organic compounds (VOCs) in breath samples. By combining gas chromatography‐mass spectrometry (GC‐MS) and electronic nose (eNose) platforms, specific VOC patterns associated with HCM are detected and analyzed.
