Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

Cardiovascular Autonomic Neuropathy in Charcot–Marie–Tooth Disease: A Genotype‐Stratified Study of PMP22 Duplication and GJB1 Mutation Carriers

open access: yesJournal of the Peripheral Nervous System, Volume 31, Issue 4, December 2026.
ABSTRACT Background and Aims Data on cardiovascular autonomic neuropathy (CAN) are sparse in Charcot–Marie–Tooth disease. We aimed to determine the prevalence of CAN in CMT1A and CMTX1 and its associations with neuropathy severity and heart rate variability (HRV), compared with age‐ and sex‐matched controls. Methods Thirty‐six CMT1A, 24 CMTX1 patients,

Pathogenic Variants in HEPACAM Alter Protein Localization and Interactome in Astrocytes of the Developing Mouse Cortex

open access: yesGlia, Volume 74, Issue 11, November 2026.
Pathogenic variants alter hepaCAM protein distribution. Astrocyte‐specific hepaCAM TurboID reveals KCNQ2 as a new interaction partner. Pathogenic variants alter hepaCAM association with key transmembrane proteins. ABSTRACT Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare leukodystrophy characterized by early‐onset macrocephaly,

Müller Glia Subtypes Define Neuro‐Glial Associations and Spatial Morphogen Axes in the Zebrafish Retina

open access: yesGlia, Volume 74, Issue 11, November 2026.
Zebrafish Müller glia are heterogeneous in the early larval retina. Zebrafish Müller glia subtypes define a spatial axis of retinoic acid metabolism. Neuron‐associated glial programs identified in Zebrafish Müller glia are evolutionarily conserved in mammals. ABSTRACT Müller glia are instrumental macroglia of the vertebrate retina, once thought to be a

Regulation of connexin 43 channels by PKC-mediated phosphorylation [PDF]

open access: yes, 2008
Gap-junctional channels communicate adjacent cells electrically and metabolically. They are formed by 4-transmembrane helix proteins called connexins; six connexins form a connexon (or gap-junctional hemichannel) and two of these, one from each ...

Uncovering the Genetic Landscape of Pediatric Hearing Loss Along the Texas–Mexico Border

open access: yesClinical Genetics, Volume 110, Issue 5, Page 627-636, November 2026.
Project GIVE provided evaluations and genome sequencing to 23 children with hearing loss along the Texas–Mexico border. Seventy percent received a molecular diagnosis and 56% of those diagnosed had changes to medical management. In this region, underdiagnosis of genetic hearing loss is due to care barriers rather than lower genetic burden.

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
