Prediction of Aortic Stenosis Progression by 18F-FDG and 18F-NaF PET/CT in Different Aortic Valve Phenotypes

Frontiers in Pharmacology, 2022
Background: Different imaging techniques, such as echocardiography (ECHO) and CT, allow to assess aortic stenosis (AS) severity and could be used to study its progression. But only PET/CT open opportunities to assess activity of valvular inflammation and

Photocatalytic Asymmetric C‐C Coupling for CO2 Reduction on Cu‐Zn Bimetallic Catalysts with Dipole‐Limiting Effects

Advanced Science, EarlyView.
Asymmetric Cu–Zn dual sites on EDTA‐grafted Ti‐MOF amplify the dipole‐limiting domain field (DLDF), facilitating C–C coupling. This strategy yields an exceptional C2H4 production rate of 308.72 µmol g−1 h−1 with 98.4% electron selectivity in photocatalytic CO2 reduction, highlighting the potential of asymmetric site engineering and local field ...

Ultrafast Electron Transfer Coupled with a Proton Relay in an Anisotropic Dual S‐Scheme Heterojunction for Overcoming Kinetics Mismatch in H2O2 Photosynthesis

Advanced Science, EarlyView.
An anisotropic dual S‐scheme heterojunction (C3N4/SubPc‐1/C3N5) is constructed to overcome the electron–proton kinetics mismatch in photocatalytic H2O2 production. The imide bridge serves as a dual channel for ultrafast electron transfer and proton relay, synergistically enabling efficient dual‐pathway oxygen reduction and achieving a high H2O2 ...

Mechanisms of Smooth Muscle Cell Differentiation Are Distinctly Altered in Thoracic Aortic Aneurysms Associated with Bicuspid or Tricuspid Aortic Valves

Frontiers in Physiology, 2017
Cellular and molecular mechanisms of thoracic aortic aneurysm are not clear and therapeutic approaches are mostly absent. Thoracic aortic aneurysm is associated with defective differentiation of smooth muscle cells (SMC) of aortic wall.

Single‐Cell Morphomechanics of Prostate Cancer‐Associated Fibroblasts Identifies Distinct Features Associated with Patient Outcome

Advanced Science, EarlyView.
Cancer‐associated fibroblasts (CAFs) in prostate tumors exhibit distinct morphomechanical traits vs normal fibroblasts, including greater stiffness and volume, more elongated stress fibres, and larger and more elongated nuclei. These features, quantified through imaging and real‐time deformability cytometry, correlate with patient outcomes and can be ...

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Long‐Term Durability of Transcatheter Aortic Valve Prostheses in Patients With Bicuspid Versus Tricuspid Aortic Valve

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Currently, there is a lack of evidence for the long‐term bioprosthetic valve durability of patients with bicuspid aortic valve (BAV) following transcatheter aortic valve replacement (TAVR).

Thoracic aortic atherosclerosis in patients with a bicuspid aortic valve; a case–control study

BMC Cardiovascular Disorders, 2023
Introduction Bicuspid aortic valve (BAV) patients have an increased risk to develop thoracic aortic complications. Little is known about the prevalence and severity of atherosclerosis in the BAV ascending aortic wall.
