Image quality, contrast enhancement and radiation dose of electrocardiograph- versus non-electrocardiograph-triggered computed tomography angiography of the aorta

Singapore Medical Journal
Introduction: Computed tomography angiography of the aorta (CTAA) is the modality of choice for investigating aortic disease. Our aim was to evaluate the image quality, contrast enhancement and radiation dose of electrocardiograph (ECG)-triggered and non-

Acute type B aortic dissection in the absence of aortic dilatation

, 2012
BackgroundIncreasing aortic diameter is thought to be an important risk factor for acute type B aortic dissection (ABAD). However, some patients develop ABAD in the absence of aortic dilatation. In this report, we sought to characterize ABAD patients who

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

Advanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

Classical supravalvar aortic stenosis and peripheral pulmonary stenosis [PDF]

, 2014
Supravalvar aortic stenosis as well as peripheral pulmonary stenosis are rare forms of congenital heart disease, which occur, however, relatively frequently in association.

Periostin‐CCL3 Feedforward Signaling Loop Promotes Cardiac Fibrosis and Cardiomyocyte Necroptosis in Arrhythmogenic Cardiomyopathy

Advanced Science, EarlyView.
POSTN‐CCL3 signaling forms a feed‐forward circuit between cardiomyocytes and cardiac myofibroblasts in arrhythmogenic cardiomyopathy. POSTN activates JNK/RIP3‐dependent necroptotic signaling and JNK/ETS2‐induced CCL3 expression in cardiomyocytes. In turn, CCL3‐CCR5 signaling in cardiac myofibroblasts activates NF‐κB/p65 and promotes POSTN expression ...

Risk factors and treatment strategies for perioperative neurological complications in aortic dissection surgery

Chinese Journal of Contemporary Neurology and Neurosurgery
Acute type A aortic dissection (aTAAD) is a common aortic disease with a very high mortality rate. Due to its frequent involvement of vessels above aortic arch, it is highly prone to cause neurological complications.

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...
