Flexible, Elastic, and Superhydrophobic/Superoleophilic Adhesive for Reusable and Durable Water/Oil Separation Coating.

This study investigates a highly flexible/stretchable and mechanically durable superhydrophobic/superoleophilic coating for efficient oil/water separation and oil absorption. The coating is applied via a simple immersion process using a mixed solution of a biocompatible adhesive (ethyl cyanoacrylate, ECA), a highly stretchable polymer (polycaprolactone, PCL), and superhydrophobic/superoleophilic nanoparticles (fluorine-coated silica nanoparticles, F-SiO NPs) in a solvent, followed by solvent evaporation and ECA polymerization. Polymerized ECA (poly-ECA) in the coating material strongly adheres the F-SiO NPs to the substrate surface, while PCL bestows the rigid poly-ECA with high flexibility.

Ultrashort Echo Time Magnetic Resonance Angiography in Follow-up of Intracranial Aneurysms Treated With Endovascular Coiling: Comparison of Time-of-Flight, Pointwise Encoding Time Reduction With Radial Acquisition, and Contrast-Enhanced Magnetic Resonance Angiography.

Background: The optimal magnetic resonance angiography (MRA) sequence for assessing the aneurysm occlusion state or in-stent flow after endovascular coiling is not well established.

Objective: To evaluate the diagnostic performance of pointwise encoding time reduction with radial acquisition (PETRA)-MRA in patients who underwent endovascular coiling relative to that of time-of-flight (TOF)-MRA and contrast-enhanced (CE)-MRA.

Methods: We evaluated the aneurysm occlusion state using digital subtraction angiography (DSA) and MRA.

Relation of coronary atherosclerosis and metabolic syndrome in asymptomatic subjects: evaluation with coronary CT angiography.

To assess the relationship between metabolic syndrome (MetS) and coronary atherosclerosis using coronary CT angiography (CCTA) as the evaluation tool in asymptomatic cardiovascular disease (CVD) free subjects. The presence and extent of coronary atherosclerosis in 755 asymptomatic self-referred subjects were measured using CCTA. The relationships between coronary atherosclerosis, MetS, and other clinical factors were assessed.
