Dynamic Single-Photon Emission Computed Tomography Data Analysis: Capabilities for Determining Functional Significance of Coronary Artery Atherosclerosis

open access: yesMATEC Web of Conferences, 2016
The aim of the study was to develop the method for collecting and processing scintigraphic data to determine myocardial flow reserve by using gamma-camera with a new type detector based on Cadmium Zinc Telluride (CZT).

THSD7A Exacerbates Atherosclerosis via Activation of Signaling Axis αvβ3/CEBPD/IL1A

open access: yesAdvanced Science, EarlyView.
THSD7A exerts pro‐inflammatory effects and exacerbates atherosclerosis. Mechanistically, THSD7A regulates endothelial cell inflammation and atherosclerosis by activating the αvβ3/CEBPD/IL1A signaling axis. THSD7A is not only a genetic marker but also a potential therapeutic target for coronary artery disease (CAD).

Longitudinal Multifrequency MR Elastography Reveals Biomechanical Signatures of Progression in a Translational Liver Tumor Model

open access: yesAdvanced Science, EarlyView.
Longitudinal multifrequency magnetic resonance elastography (mMRE) performed on a clinical 3 Tesla magnetic resonance imaging system reveals early biomechanical alterations during liver tumor progression in a translational VX2 model. Changes in tumor stiffness and viscosity precede diffusion‐related alterations and are associated with extracellular ...

Prognostic implication of thermodilution coronary flow reserve in patients with indeterminate pressure-bounded coronary flow reserve

open access: yesInternational Journal of Cardiology, 2018
Recently, the concept of pressure-bounded coronary flow reserve (PB-CFR) has been introduced. However, using pressure-only data, a substantial proportion of patients could not be classified into high or low PB-CFR and remained as indeterminate PB-CFR.

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

open access: yesAdvanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

open access: yesAdvanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

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

open access: yesAdvanced 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.

Beta-Blockers and Coronary Flow Reserve

open access: yes, 2011
The knowledge of the impact of beta-blockers on Coronary Flow Reserve (CFR) is based on experimental and clinical studies which used invasive methods (mainly Doppler Flow Wire, DFW) and non-invasive tools including scintigraphic (mainly Positron Emission Tomography, PET), magnetic resonance and Doppler ultrasound imaging.
