Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Extremity Function After Transfemoral Transcatheter Aortic Valve Implantation: A TAVI XS Sub‐Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Physical decline after transcatheter aortic valve implantation (TAVI) is associated with worse outcomes. However, data on post‐TAVI extremity function are limited. This sub‐study of the TAVI XS trial aimed to assess extremity function after transfemoral TAVI, evaluate functional decline, compare outcomes between upper‐and lower ...

Local Intracoronary Eptifibatide versus Mechanical Aspiration in Patients with Acute ST-Elevation Myocardial Infarction

International Journal of Vascular Medicine, 2014
Objectives. We compared local delivery of intracoronary eptifibatide via perfusion catheter to thrombus aspiration in primary PCI. Background. Perfusion catheter increases local concentration of the drugs at the culprit site and prolongs their residency ...

Feasibility and Safety of the ETcath200 Robotic PCI System for Complex Coronary Lesions: A Prospective Single‐Center Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background International robotic‐assisted PCI platforms such as CorPath 200 and CorPath GRX have demonstrated procedural safety and efficacy but are limited by the absence of real‐time tactile feedback and cumbersome device exchange. The ETcath200, the first domestically developed robotic PCI system in China, introduces guidewire force‐sensing

A bibliometric and social network analysis perspective of X‐ray phase‐contrast imaging in medical imaging

Journal of Medical Radiation Sciences, 2022
Introduction Phase‐contrast imaging (PCI) is a novel technology that can visualise variations in X‐ray refraction (phase contrast) in addition to differences in X‐ray attenuation (absorption contrast).

The Prognostic Impact of Multiple Adverse Events on Long‐Term Mortality Following Acute Myocardial Infarction

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Adverse events after acute myocardial infarction (AMI) are individually associated with poor outcomes, but the prognostic impact of the overlap of different event types occurring sequentially within the same patient remains uncertain.
