Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

The apicobasal dispersion of ventricular repolarization in humans is associated with age and affects arrhythmia vulnerability

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated the age‐ and sex‐related differences in the apicobasal repolarization gradient (ABRG) and evaluated their possible role inventricular arrhythmia vulnerability. Electrocardiographic imaging (ECGI) was performed in healthy subjects during sinus rhythm, and the average recovery time (RT) and activation–recovery ...

What Does Iron Mean to an Oligodendrocyte?

Glia, Volume 73, Issue 9, Page 1784-1804, September 2025.
Main Points Iron is essential for oligodendrocyte (OL) biology and myelin production, with deficiencies leading to severe neurological impairments. Understanding iron trafficking in OLs is crucial for developing treatments for dysmyelinating conditions. ABSTRACT Iron is essential for life and plays a key role in multiple fundamental cellular functions.

Understanding the Enigmatic Dance of Immune‐Mediated Viral Infections and Their Pathogenetic Mechanisms

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
This graphical representation illustrates the multifaceted nature of the immune response in viral infections, demonstrating both its protective and potentially harmful aspects. While a properly regulated immune reaction facilitates viral clearance and promotes general recovery, an overly robust or misdirected response—exemplified by Type III or Type IV

Sinoatrial Contracaeciasis in Johnny Darters (Etheostoma nigrum) and Plains Topminnow (Fundulus sciadicus) From the South Platte Drainage, Colorado

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Intra‐sinoatrial nematodes were incidentally recognized in wild‐caught Colorado Johnny Darters (Etheostoma nigrum, JD) in 2020–2021 and in Colorado Plains Topminnow (Fundulus sciadicus, PTM) in 2023‐2024. PTM and JD were evaluated histologically.
