Atrial fibrillation versus non-atrial fibrillation coronary embolism.

Background: Coronary embolism (CE) is an uncommon cause of non-atherosclerotic acute myocardial infarction (AMI). Although atrial fibrillation (AF) is the main cause of CE, evidence of clinical, biochemical, echocardiographic, angiographic findings and outcomes of AF CE is lacking.

Methods: We retrospectively analyzed 85 consecutive patients with CE that was diagnosed based on criteria encompassing clinical, angiographic and diagnostic imaging findings.

Low muscle mass index is associated with type 2 diabetes risk in a Latin-American population: a cross-sectional study.

Objective: Diabetes mellitus is a growing disease with severe complications. Various scores predict the risk of developing this pathology. The amount of muscle mass is associated with insulin resistance, yet there is no established evidence linking muscle mass with diabetes risk.

Long-term prognostic value of quantitative-flow-ratio-concordant revascularization in stable coronary artery disease.

Objectives: Confirming the prognostic value of global QFR and evaluating the long-term prognosis of QFR-concordant therapy in stable coronary artery disease.

Background: Wire-based functional evaluation of coronary disease is linked to patient's prognosis. Quantitative Flow Ratio (QFR) is a newer index of computational physiology, linked to clinical outcomes and prognosis at 1 year follow-up.

Optimal High-Dimensional Entanglement Concentration for Pure Bipartite Systems.

Considering pure quantum states, entanglement concentration is the procedure where, from copies of a partially entangled state, a single state with higher entanglement can be obtained. Obtaining a maximally entangled state is possible for N=1. However, the associated success probability can be extremely low when increasing the system's dimensionality.

Design of Ti64/Ta Hybrid Materials by Powder Metallurgy Mimicking Bone Structure.

This work reports on the fabrication of a novel two-layer material composed of a porous tantalum core and a dense Ti6Al4V (Ti64) shell by powder metallurgy. The porous core was obtained by mixing Ta particles and salt space-holders to create large pores, the green compact was obtained by pressing. The sintering behavior of the two-layer sample was studied by dilatometry.
