DOI: 10.1016/j.jacc.2020.04.043
Abstract: BACKGROUND Subclinical leaflet thrombosis, characterized by hypoattenuated leaflet thickening (HALT) and reduced leaflet motion observed on 4-dimensional computed tomography (CT), may represent a form of bioprosthetic valve dysfunction. OBJECTIVES The U.S. Food and Drug Administration… read more here.

DOI: 10.1021/acs.inorgchem.5c03352
Abstract: In this study, we demonstrate that an excess of the nonselective chelator EDTA can effectively extract both copper(II) and zinc(II) from the amyloid-β (Aβ) peptide and halt Cu(Aβ)-catalyzed ROS production in the context of Alzheimer's… read more here.

Reciprocating Motion of a Self-Propelled Rotor Induced by Forced Halt and Release Operations
Sign Up to like & getrecommendations! Published in 2018 at "Journal of Physical Chemistry C"
DOI: 10.1021/acs.jpcc.7b12089
Abstract: We studied rotational motion of a symmetric self-propelled object on water under periodic halt and release operations with an external force. We propose a novel system in which the direction of rotation inverts after each… read more here.

DOI: 10.1053/j.jvca.2024.06.043
Abstract: Nearly one-third of patients who undergo surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) develop hypoattenuated leaflet thickening (HALT) within a year. HALT typically represents subclinical leaflet thrombosis in asymptomatic patients, and… read more here.

DOI: 10.1093/eurheartj/ehae666.185
Abstract: Hypo-attenuating leaflet thickening (HALT) after transcatheter aortic valve replacement (TAVR) occurs in up to 25% of patients and is characterized by diverse temporal dynamics. Several studies investigated the natural history of HALT in transcatheter and… read more here.

Sign Up to like & getrecommendations! Published in 2017 at "European Heart Journal"
DOI: 10.1093/eurheartj/ehx369
Abstract: Aims Four-dimensional volume-rendered computed tomography (4DCT) has demonstrated instances of hypo-attenuating leaflet thickening (HALT) with or without hypo-attenuation affecting motion (HAM) after transcatheter and surgical aortic valve implantation (TAVI, SAVR). The temporal pattern of evolution… read more here.

DOI: 10.1136/jnis-2023-020220
Abstract: Background Large vessel recanalization (LVR) before endovascular therapy (EVT) for acute large vessel ischemic strokes is a poorly understood phenomenon. Better understanding of predictors for LVR is important for optimizing stroke triage and patient selection… read more here.
