Perfusion of the interventricular septum during ventilation with positive end-expiratory pressure (PEEP) [PDF]

, 1991
Objective: To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. Design: Animal study. Animals: Anesthetized, closed chest dogs (n = 8).

On-Pump Beating Heart Endoventriculoplasty Using Autologous Endocardium for Left Ventricular Aneurysm Repair

Balkan Medical Journal, 2011
The operative goals of the repair of postinfarction left ventricular aneurysms are to correct the size and geometry of the left ventricle in order to reduce wall tension and paradoxical movement and to improve the systolic function. Endoventriculoplasty

Impact of Prehypertension on Left Ventricular Structure, Function and Geometry

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2014
Awareness of prevalence, determinants, and prognosis of asymptomatic untreated prehypertension is still lacking especially in India and subcontinent. The present study was to assess the effects of prehypertension on structure, function and geometrical pattern of left ventricle on the basis of left ventricular mass (LVM), left ventricular mass indexed ...

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

Advanced Science, EarlyView.
Smart bioinks empower 4D‐bioprinted constructs to dynamically adapt and remodel in response to stimuli, effectively biomimicking native tissues. Artificial Intelligence (AI) and Machine Learning (ML) play a guiding role in their rational design by optimizing relevant properties.

Transverse left ventricular band

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Left ventricular band has been considered a vestigial entity for quite a long time. Their incidence is quite common in our day to day practise but their real function is yet to be understood. We performed a case series of 5 patients with left ventricular

Thickness‐Gradient Liquid Metal Connectors for Seamless Electrophysiological Sensors

Advanced Science, EarlyView.
Thickness‐gradient liquid metal interfaces with elastomeric substrates enable seamless integration between ultrathin skin‐conformal electrodes and external interconnects. The mechanically compliant connector reduces interfacial mismatch and supports stable ECG/EMG monitoring under bending and motion.

Left ventricular geometry predicts ventricular tachyarrhythmia in patients with left ventricular systolic dysfunction: a comprehensive cardiovascular magnetic resonance study

Journal of Cardiovascular Magnetic Resonance, 2017
Background Most patients with implantable cardioverter-defibrillator (ICD) implantation fail to utilize the device resulting in increasing societal costs and patient exposure to device morbidity.

Retrospective Grid Cells in the Medial Entorhinal Cortex Encode Past Paths During Spatial Navigation

Advanced Science, EarlyView.
Retrospective grid cells are identified in the medial entorhinal cortex, with spatial firing patterns that become most grid‐like when activity is projected onto recently traversed locations. Their coding loses spatial precision in darkness and is disrupted during assisted movement, indicating that entorhinal representations incorporate recent path ...

Salvianolic Acid a Disrupts the HSP90α‐AKT‐PERK Ternary Complex to Alleviate Atherosclerosis by Activating Endoplasmic Reticulum Stress of Senescent Vascular Smooth Muscle Cells

Advanced Science, EarlyView.
Salvianolic acid A (SAA) selectively induces senescent vascular smooth muscle cell apoptosis, alleviating atherosclerosis. Mechanistically, SAA targets heat shock protein 90 alpha (HSP90α) to disrupt the protein inase B (AKT)‐PRKR‐Like Endoplasmic Reticulum Kinase (PERK) scaffold, driving ubiquitin‐proteasome‐dependent AKT degradation.
