Feasibility and Safety of High‐Power Settings for Electrical Isolation of the Superior Vena Cava Using a Catheter Capable of Local Impedance and Contact Force Monitoring

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
High‐power superior vena cava isolation using a contact force– and local impedance–sensing catheter achieved safe and consistent first‐pass isolation. Local impedance decreased more rapidly than generator impedance, accurately reflecting effective lesion formation and enabling reliable real‐time assessment in thin SVC myocardium.

Exacerbated ATP transmission in the carotid body is linked to glomus cell expansion in spontaneously hypertensive rats

The Journal of Physiology, Volume 604, Issue 12, Page 4678-4706, 15 June 2026.
Abstract figure legend Exacerbated ATP signalling in the carotid body (CB) of spontaneously hypertensive rats (SHRs) arises from expansion of the chemosensory glomus cell compartment and reduced extracellular ATP metabolism, leading to increased purinergic drive.

Mapping of Physiological Signals From Wireless Battery‐Free Implants With Plane‐Wave Ultrasound Imaging

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.

Phrenic nerve transfer to the musculocutaneous nerve for the repair of brachial plexus injury: electrophysiological characteristics

Neural Regeneration Research, 2015
Phrenic nerve transfer is a major dynamic treatment used to repair brachial plexus root avulsion. We analyzed 72 relevant articles on phrenic nerve transfer to repair injured brachial plexus that were indexed by Science Citation Index.

The Thoracic Lymphatic Vasculature: Interorgan Strategies to Achieve an Optimal Tissue Function

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
In the thorax, organ‐specific features such as stomata and submesothelial lacunae, pulmonary perivascular and peribronchial vessels, and subepicardial lymphatic network allow the thoracic lymphatics to perform as a dynamically regulated system able to exploit local mechanical forces and tissue‐specific architecture to maintain fluid and solute ...

Heterogeneous glutamatergic receptor mRNA expression across phrenic motor neurons in rats

Journal of Neurochemistry, 2019
AbstractThe diaphragm muscle comprises various types of motor units that are recruited in an orderly fashion governed by the intrinsic electrophysiological properties (membrane capacitance as a function of somal surface area) of phrenic motor neurons (PhMNs).

Neurochemical assessment of identified phrenic motor neurons via flow cytometry

The FASEB Journal, 2013
Flow cytometry (FCM) utilizes high powered, laser‐based tools to perform multi‐parametric analyses on cell populations. Although FCM is routinely utilized in immunology and cancer biology fields, it is rarely used in the study of neurobiology. Here, we show a novel use of FCM to identify and isolate phrenic motor neurons, a small, but critical pool of ...

Phrenic Motor Neuron Survival Below a Cervical Spinal Cord Injury

The FASEB Journal, 2018
Cervical spinal injury (cSCI) severs descending brainstem projections to spinal respiratory motor neurons, paralyzing respiratory muscles caudal to injury. Spinal hemisection at C2 (C2Hx) has frequently been used as an experimental model of cSCI to study both spontaneous and induced functional recovery of respiratory and non‐respiratory somatic motor ...

Distribution of Ipsilateral and Contralateral Glutamatergic Synaptic Inputs to Phrenic Motor Neurons

The FASEB Journal, 2019
Excitatory descending glutamatergic (Glu) synaptic input to phrenic motor neurons (PhMNs) emanates from the ventrolateral medulla and is responsible for inspiratory drive and a range of higher force behaviors. Disruption of this excitatory input following unilateral C2 hemisection (C2SH) results in cessation of inspiratory‐related diaphragm muscle ...
