A rhesus macaque model of α‐dystroglycanopathy caused by a POMT1 splice altering variant

Animal Models and Experimental Medicine, EarlyView.
Rhesus macaques homozygous for a naturally occurring spice altering variant in the POMT1 gene develop lissencephaly, microphthalmia, and muscular contracture. The presentation models severe presentation of the human Walker‐Warburg syndrome. Abstract Background Biallelic mutations in genes associated with α‐dystroglycan glycosylation manifest in a ...

Silk Fibroin for Cardiovascular Medical Devices: Review of Material Properties, Applications, and Clinical Potential

Advanced NanoBiomed Research, EarlyView.
Silk fibroin is an attractive natural biomaterial that can be engineered into diverse cardiovascular constructs, including vascular grafts, cardiac patches, heart valves, and stent coatings. Its tunable biological and mechanical properties have driven substantial preclinical progress; however, widespread clinical translation in cardiovascular ...

Frequency analysis of premature ventricular contraction using 3-DMCG measurements [PDF]

, 2009
The authors carried out three-dimensional (3-D) vector measurements of the magnetocardiogram (MCG) on a subject with premature ventricular contraction (PVC) and ten normal subjects using a 39-channel SQUID system.

Classification of Arrhythmia by Using Deep Learning with 2-D ECG Spectral Image Representation

Remote Sensing, 2020
The electrocardiogram (ECG) is one of the most extensively employed signals used in the diagnosis and prediction of cardiovascular diseases (CVDs). The ECG signals can capture the heart’s rhythmic irregularities, commonly known as arrhythmias.

Visualization of Minute Mechanical-Excitation/Relaxation Wave-front Propagation in Myocardial Tissue [PDF]

, 2010
Unlike the case of skeletal muscle, the direction of myocardial contraction does not coincide with the direction of work necessary to eject the intraventricular blood, contributing to great complexity of the wall deformation sequence of cardiac ...

Acute effects of THC and a CBD+THC combination on cardiovascular haemodynamics and respiratory muscle activity during loaded breathing in healthy adults: A randomized placebo‐controlled crossover study

British Journal of Clinical Pharmacology, EarlyView.
Aims This study aimed to evaluate the acute effects of cannabidiol plus tetrahydrocannabinol (CBD+THC) and tetrahydrocannabinol (THC) oils on cardiovascular haemodynamics, respiratory muscle activity and peripheral tissue perfusion in healthy adults. Methods In this randomized, double‐blind, crossover trial, participants received orally administered ...

The evolution of supraventricular and ventricular premature beats in children [PDF]

, 2022
Background. Supraventricular premature beats represent premature activation of the atria from a site other than the sinus node and can originate from the atria, a premature ventricular beats is caused by an ectopic cardiac pacemaker located in the ...

Ablation of idiopathic ventricular fibrillation targeting short coupled ventricular premature contractions originating from a right ventricular papillary muscle [PDF]

, 2014
We describe a 38-year-old male who experienced several episodes of syncope after having ventricular fibrillation. The electrocardiographic monitoring after his hospitalization revealed repetitive polymorphic ventricular tachycardias.

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

BMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.

Use of Catheter Ablation in the Treatment of Ventricular Tachycardia Triggered by Premature Ventricular Contraction [PDF]

, 2006
A 50-year-old man who had suffered from old myocardial infarction presented with an episode of syncope. DC shock was required for the interruption of frequent pleomorphic ventricular tachycardia (VT).
