Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Impact of Renal Impairment on Beta-Blocker Efficacy in Patients With Heart Failure. [PDF]

, 2019
BACKGROUND: Moderate and moderately severe renal impairment are common in patients with heart failure and reduced ejection fraction, but whether beta-blockers are effective is unclear, leading to underuse of life-saving therapy.

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

First-phase ejection fraction for evaluating early left ventricular systolic function in patients with cirrhosis

Journal of International Medical Research
Purpose First-phase ejection fraction has been established as an innovative indicator for detecting early left ventricular systolic changes. This study aimed to use first-phase ejection fraction to assess early changes in the left ventricular systolic ...

Galectin-3, advanced glycated end-products serum levels, endothelial function and cardiac hemo¬dynamics in post infarction heart failure patients with reduced and preserved ejection fraction.

Medičnì Perspektivi, 2018
Epidemiological studies have reported that the rate of signs and symptoms of heart failure after myocardial infarction is approximately 25%. In addition, approximately 40% of myocardial infarctions are accompanied by left ventricular systolic dysfunction.

Heart Failure With Preserved Ejection Fraction

Journal of Osteopathic Medicine, 2015
Abstract Heart failure with preserved ejection fraction (HFpEF) is a complex clinical condition. Initially called diastolic heart failure, it soon became clear that this condition is more than the opposite side of systolic heart failure. It is increasingly prevalent and lethal.

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Prognostic Value of Epicardial Adipose Tissue in Heart Failure With Mid‐Range and Preserved Ejection Fraction: A Multicenter Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Epicardial adipose tissue (EAT) accumulation is thought to play a role in the pathophysiology of heart failure (HF) with mid‐range ejection fraction and HF with preserved ejection fraction, but its effect on outcome is unknown.
