Validation of a new noninvasive method (contrast-enhanced transthoracic second harmonic echo Doppler) for the evaluation of coronary flow reserve Comparison with intracoronary Doppler flow wire [PDF]

OBJECTIVESWe tested the hypothesis that coronary flow reserve (CFR) in the left anterior descending coronary artery (LAD) as assessed by a new noninvasive method (contrast-enhanced transthoracic second harmonic echo Doppler) is in agreement with CFR ...

Biomarkers of coronary endothelial health: correlation with invasive measures of collateral function, flow and resistance in chronically occluded coronary arteries and the effect of recanalization [PDF]

, 2016
Objectives: In the presence of a chronically occluded coronary artery, the collateral circulation matures by a process of arteriogenesis; however, there is considerable variation between individuals in the functional capacity of that collateral network ...

Pushing the Frontiers: Artificial Intelligence (AI)‐Guided Programmable Concepts in Binary Self‐Assembly of Colloidal Nanoparticles

Advanced Science, EarlyView.
Colloidal nanoparticles self‐assembly advances towards intelligent, customized assembly through precise control of binary co‐assemblies. This review explores the evolution from monolithic to binary assemblies, highlighting how the AI‐guided programmable assembly approach has the potential to shift from passive assembly to active intelligent design.

Imaging Techniques for the Assessment of Coronary Flow Reserve

European Cardiology Review, 2008
Myocardial blood flow (MBF) must respond to changes in metabolic conditions and oxygen requests to meet the needs of myocytes, and autoregulation plays a mayor role in the control of coronary circulation.1–3 It has been demonstrated that, as a coronary artery is progressively narrowed, resting flow does not change at first, but maximal flow (achieved ...

Identification of Schwann Cells in Human Intracranial Arteries: Potential Regulatory Role in Atherosclerotic Plaque Progression

Advanced Science, EarlyView.
Schwann cells may facilitate intracranial plaque progression via neurovascular remodelingcting with vascular smooth muscle cells in atherosclerotic plaques, with the SPP1 ‐ ITGB1 signaling axis mediating this interaction as a novel mechanism. Abstract Intracranial atherosclerosis (ICAS), a common cause of ischemic stroke, remains a therapeutic ...
