Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction

Acta Physiologica, Volume 242, Issue 8, August 2026.
ABSTRACT Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI.

Gβγ subunit activation of KV7 and BKCa channels underlies calcitonin gene‐related peptide vasorelaxation in myogenic rat coronary resistance arteries

British Journal of Pharmacology, Volume 183, Issue 16, Page 5018-5032, August 2026.
Abstract Background and Purpose CGRP is a potent, clinically relevant coronary vasodilator known to play a role in cardioprotection. Here, we investigated the precise intracellular signalling pathways leading to vasodilation in small coronary arteries.

Refined Division of Sleep Stages in the Mouse Based on Distributed Deep Electrodes and Underlying Infra‐Slow Oscillation

Journal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

Advanced Materials, Volume 38, Issue 39, 13 July 2026.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...
