Correlates of the “No-Reflow” or “Slow-Flow” Phenomenon in Patients Undergoing Primary Percutaneous Coronary Intervention

Journal of Tehran University Heart Center, 2018
Background: Despite recent advances in interventional equipment and techniques, the angiographic no-reflow phenomenon occurs in a considerable number of patients undergoing primary percutaneous coronary intervention (PCI).

"No-reflow" phenomenon in acute ischemic stroke. [PDF]

J Cereb Blood Flow Metab, 2023
Acute ischemic stroke (AIS) afflicts millions of individuals worldwide. Despite the advancements in thrombolysis and thrombectomy facilitating proximal large artery recanalization, the resultant distal hypoperfusion, referred to “no-reflow” phenomenon, often impedes the neurological function restoration in patients.

The no-reflow phenomenon: State of the art

Archives of Cardiovascular Diseases, 2015
Primary percutaneous coronary intervention (PCI) is the best available reperfusion strategy for acute ST-segment elevation myocardial infarction (STEMI), with nearly 95% of occluded coronary vessels being reopened in this setting. Despite re-establishing epicardial coronary vessel patency, primary PCI may fail to restore optimal myocardial reperfusion ...

The no-reflow phenomenon in the young and in the elderly

International Journal of Cardiology, 2016
The objectives of this study were to evaluate the incidence of no-reflow as independent predictor of adverse events and to assess whether baseline pre-procedural treatment options may affect clinical outcomes.Data were derived from the ISACS-TC registry (NCT01218776) from October 2010 to January 2015.

Temperature‐Resilient Reconfigurable Physical Unclonable Function Driven by Pulse Modulation Using CMOS‐Integrated Spintronic Chips

Advanced Science, EarlyView.
A reconfigurable physical unclonable function is developed using CMOS‐integrated SOT‐MRAM chips, leveraging a dual‐pulse strategy and offering enhanced environmental robustness. A temperature‐compensation effect arising from the CMOS transistor and SOT‐MTJ is revealed and established as a key prerequisite for thermal resilience.

A Biomimetic Nanoparticle System Intercepts and Degrades Thrombospondin‐1 to Restore Vascular Homeostasis After Ischemic Injury

Advanced Science, EarlyView.
TAX2‐NPs capture extracellular TSP‐1 in the injured liver and promote its macrophage‐mediated autophagic degradation. This process blocks TSP‐1/CD47 signaling, restores VEGFR2‐AKT activity, preserves endothelial function, and mitigates hepatic ischemia‐reperfusion injury.

Electric‐Current‐Induced Phase Transformation in Cu6Sn5 Below Its Equilibrium Transition Temperature

Advanced Science, EarlyView.
Electric current induces a monoclinic‐to‐hexagonal phase transformation in Cu6Sn5 at a measured bulk temperature of ∼120°C, below the equilibrium transition temperature. Ex situ synchrotron x‐ray diffraction, TEM, and matched thermal controls show that current stressing promotes the formation of a retained hexagonal η‐phase post‐stress state not ...
