Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

α‐Synuclein oligomers slow down action potential firing and enhance dopamine release by increasing Cav2.2 currents in midbrain dopaminergic neurons

The Journal of Physiology, EarlyView.
Abstract figure legend Left: the spontaneous quantal release of dopamine (DA) occurs at very low frequency in control conditions. Right: exogenous α‐synuclein potentiates Cav2.2 currents and DA release but drastically reduces the spontaneous firing rate of substantia nigra DA neurons.

Pharmacological manipulation of the immediate effects of spinal trauma in neonatal rats reveals a crucial role for TRPV4 receptors

The Journal of Physiology, EarlyView.
Abstract figure legend A, schematic illustration of the ventral aspect of an ex vivo preparation of the entire CNS from a neonatal rat subjected to a calibrated thoracic impact. The trauma induced a large depolarising injury potential (DIP, black trace) recorded from the L5 ventral root (VRrL5), which was markedly reduced by transient receptor ...

Certain Geometric Investigations of Three Normalized Bessel-Type Functions of a Complex Variable

Mathematics
We recall the normalized forms for the three Bessel-type functions; these functions are the Bessel function, Lommel function, and Struve function of the first kind. By using convolution, we define normalized forms.

Alpha‐adrenergic mediated changes in blood pressure variability after hypoxia‐ischaemia in preterm fetal sheep

The Journal of Physiology, EarlyView.
Abstract figure legend Clinical detection of brain injury in preterm infantsremains a significant challenge. We investigated whether evolving brain injuryafter severe hypoxia‐ischaemia (HI) in chronically instrumented preterm fetalsheep is associated with dynamic changes in arterial blood pressure variability(BPV) and tested the hypothesis that post‐HI

An expansion formula for the H-function of two variables

Revista Técnica de la Facultad de Ingeniería, 2011
The object of this note is to evaluate an integral associated with Bessel polynomials and the H-function of two variables and to apply it in proving an expansion formula for the H-function of two variables in series of product of the Bessel polynomials ...

Jointly Learned 3D Non‐Cartesian Sampling With Wave Encoding and Reconstruction for Neurovascular Phase Contrast MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2554-2567, May 2026.
ABSTRACT Purpose To develop accelerated 3D phase contrast (PC) MRI using jointly learned wave encoding and reconstruction. Methods Pseudo‐fully sampled neurovascular 4D flow data (N = 40) and a simulation framework were used to learn phase encoding locations, wave readout parameters, and model‐based reconstruction network (MoDL) for a rapid 3D PC scan (

Repeatability of Rapid Human Cardiac Phosphorus MRSI (31P‐MRSI) Using Concentric Ring Trajectory Readouts at 7 T

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2508-2514, May 2026.
ABSTRACT Purpose PCr/ATP ratio is determined at 7 T typically using Fourier‐transform based magnetic resonance spectroscopic imaging sequences (FT‐MRSI). These sequences require acquisition times longer than desirable for inclusion in cardiac clinical trials. Concentric ring trajectory (CRT‐MRSI) has been described as an accelerated alternative k‐space

Influence of Variations in Gravity Wave Properties on Cirrus Ice Number Concentrations Produced by Homogeneous Freezing in the Tropical Tropopause Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract In this study, we examine the impact of variations in gravity wave properties on the ice crystal number concentrations in the tropical tropopause layer (TTL). Analysis of quasi‐Lagrangian superpressure balloon measurements from the Stratéole‐2 campaign shows that high‐frequency waves dominate the occurrence of relatively large vertical wind ...
