Left ventricular systolic function in aortic stenosis [PDF]

, 2017
In aortic valve stenosis, concentric hypertrophy develops which is characterized by a reduced end-diastolic radius-to-wall thickness ratio (r/h) with an essentially normal cavity shape.

How to diagnose heart failure with preserved ejection fraction: the HFA–PEFF diagnostic algorithm: a consensus recommendation from the Heart Failure Association (HFA) of the European Society of Cardiology (ESC)

European Journal of Heart Failure, 2020
Making a firm diagnosis of chronic heart failure with preserved ejection fraction (HFpEF) remains a challenge. We recommend a new stepwise diagnostic process, the ‘HFA–PEFF diagnostic algorithm’.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery

Advanced Functional Materials, EarlyView.
This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

Sex differences in heart failure with preserved ejection fraction: From traditional risk factors to sex-specific risk factors

Women's Health, 2022
Heart failure with preserved ejection fraction has a higher prevalence in women versus men. There are several proposed mechanisms to explain this sex discrepancy including differences in cardiovascular adaptation to comorbidities and potential underlying

Left ventricular function at 24 hours, 14 days and 6 months after acute myocardial infarction [PDF]

, 2017
To determine the natural history of left ventricular function at rest and during exercise and to assess the impact of this variable on subsequent mortality, 165 patients were studied with radionuclide angiography within 24 hours of acute myocardial ...

The properties of dynamically ejected runaway and hyper-runaway stars

, 2012
Runaway stars are stars observed to have large peculiar velocities. Two mechanisms are thought to contribute to the ejection of runaway stars, both involve binarity (or higher multiplicity).

Fluoride‐Free Molten Salt Hydrate‐Assisted Synthesis of MXene in Air Down to 150 °C

Advanced Functional Materials, EarlyView.
A novel low‐temperature shielded salt (LSS) approach enables the synthesis of MXenes in air at temperatures as low as 150 °C using MgCl2·6H2O/LiCl. This method demonstrates successful etching of challenging MXenes like Cr2CTx and Nb2CTx through the synergistic effects of Li+ ions and salt hydrate phase changes, while eliminating the need for inert ...

Functional Assessment of Heart Failure Patients

, 2015
Heart failure (HF) is the condition characterized by the inability of the heart to pump sufficient blood to meet the demands of the body. It has been well established that both the prevalence and incidence of HF is increasing.1 There are 2 primary types ...

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

Advanced Functional Materials, EarlyView.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.
