Acute Inhalation Exposure to Ultrafine Carbon Black Alters Mitochondrial Substrate Utilization in the Heart

Environmental Toxicology, EarlyView.
ABSTRACT A majority of deaths associated with air pollution are attributed to cardiovascular and heart diseases. Carbon black that represents the carbon core of particulate matter, a major component of air pollution, has been shown to result in cardiac mitochondrial dysfunction.

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Comparison of Intraoperative Doppler Flow Measurements and Algorithmic Flow Estimations in Patients Undergoing Durable Left Ventricular Assist Device Implantation

Artificial Organs, EarlyView.
Direct intraoperative HeartMate 3 LVAD flow measurements using an ultrasonic probe revealed consistently higher values by approximately 0.5 L/min compared to device‐estimated flows. This discrepancy remained stable across pump speed settings, highlighting the importance of distinguishing measured from estimated flow in HeartMate 3 patients.

Variable electrophysiology before and after block of the two delayed rectifier potassium channels in groups of isolated rabbit ventricular cells

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Between‐cell differences in ventricular cardiomyocyte action potential duration (APD) and responses to ion channel block may contribute to pro‐arrhythmic dispersion of myocardial repolarisation. This study quantifies between‐cell physiological and pharmacological variability in the rabbit left ventricle (LV) and uses ...

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.
