Defect Engineering and Effect of Vacancy Concentration on the Electrochemical Performance of V‐Based MXenes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a top‐down defect engineering approach, controllable vacancy concentrations are introduced into V‐based MXenes by rationally designing the precursor MAX phase, aiming to investigate the effect of vacancy concentration on the electrochemical performance.

Why is VO2 max after altitude acclimatization still reduced despite normalization of arterial O2 content?

open access: yesAmerican Journal of Physiology. Regulatory Integrative and Comparative Physiology, 2003
Acute hypoxia (AH) reduces maximal O2 consumption (VO2 max), but after acclimatization, and despite increases in both hemoglobin concentration and arterial O2 saturation that can normalize arterial O2 concentration ([O2]), VO2 max remains low.

Comprehensive exploration of unexplained dyspnoea in subjects with normal ejection fraction and low natriuretic peptides

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 879-887, April 2025.
Abstract Background Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF). Aims This study aimed to characterize patients with exertional dyspnoea and normal/near‐to‐normal N‐terminal pro‐brain natriuretic peptide (NT ...

Considerations for drug trials in hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.
