Pre-operative Tei Index does not predict left ventricular function immediately after mitral valve repair

Annals of Cardiac Anaesthesia, 2012
Echocardiographic assessment of systolic left ventricular (LV) function in patients with severe mitral regurgitation (MR) undergoing mitral valve (MV) repair can be challenging because the measurement of ejection fraction (EF) or fractional area change ...

A randomly-controlled study on the cardiac function at the early stage of return to the plains after short-term exposure to high altitude. [PDF]

PLoS ONE, 2012
High altitude acclimatization and adaptation mechanisms have been well clarified, however, high altitude de-adaptation mechanism remains unclear. In this study, we conducted a controlled study on cardiac functions in 96 healthy young male who rapidly ...

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Comparisons of serum non-transferrin-bound iron levels and fetal cardiac function between fetuses affected with hemoglobin Bart’s disease and normal fetuses

Frontiers in Medicine, 2023
ObjectiveTo compare the levels of Non-transferrin bound iron (NTBI) in fetuses with anemia, using Hb Bart’s disease as a study model, and those in unaffected fetuses and to determine the association between fetal cardiac function and the levels of NTBI ...
