Pulsed Radiofrequency of Stellate Ganglion for Neuropathic Pain Associated with Recurrent Pleural Leiomyosarcoma - A Case Report

Indian Journal of Palliative Care, 2021
Pleural leiomyosarcomas are rare soft-tissue sarcomas. Neuropathic pain associated with such tumours can be quite debilitating. We present the case of a 62-year-old woman with chronic neuropathic pain refractory to pharmacologic interventions in association with recurrent pleural leiomyosarcoma.

Facilitation of excitatory post-synaptic potentials in the giant cell in the left pleural ganglion of Aplysia californica [PDF]

Comparative Biochemistry and Physiology A, Comparative Physiology, 1972
Abstract 1. 1. Heterosynaptic facilitation (HSF) was found to begin to develop after a latency of between 1900 and 2000 msec after which the amplitude of HSF increased as a function of the prime test interval. 2. 2. Changes in the amplitude of the HSF could last as long as 42 hr. 3. 3.

At the crossroad between Ewing sarcoma and neuroblastoma: a report of two cases of Ewing sarcoma with post treatment neuroblastoma-like differentiation [PDF]

Diagnostic Pathology
Background Ewing sarcoma (ES) is the second most frequent sarcoma of bone, often affecting young patients and pursuing an aggressive clinical course. Among therapeutic choices, radio- and chemotherapy are employed in neoadjuvant setting, and they yield ...

Simplified left cardiac sympathetic denervation as an acute strategy for recurrent ventricular tachycardia in multimorbid patients with structural heart disease: A case series [PDF]

Heart Rhythm O2
Background: Cardiac sympathetic denervation as a treatment for drug-refractory ventricular arrhythmias (VAs) involves video-assisted thoracoscopic removal of the stellate ganglion (SG) and thoracic ganglia.

Changes in Metabolism and Proteostasis Drive Aging Phenotype in Aplysia californica Sensory Neurons

Frontiers in Aging Neuroscience, 2020
Aging is associated with cognitive declines that originate in impairments of function in the neurons that make up the nervous system. The marine mollusk Aplysia californica (Aplysia) is a premier model for the nervous system uniquely suited to ...

Neurogenesis of the scallop Azumapecten farreri: from the first larval sensory neurons to the definitive nervous system of juveniles

Frontiers in Zoology, 2022
Background Scallops are among the best-studied bivalve mollusks. However, adult nervous system and neurogenesis studies of scallops are limited. Here, we studied the localization of neurotransmitters (serotonin/5-HT, FMRFamide, catecholamines) in adult ...

Identified FMRFamide-immunoreactive neuron LPL16 in the left pleural ganglion of Aplysia produces presynaptic inhibition of siphon sensory neurons [PDF]

The Journal of Neuroscience, 1992
The gill- and siphon-withdrawal reflex of Aplysia undergoes transient inhibition following noxious stimuli such as tail shock. This behavioral inhibition appears to be due in part to transient presynaptic inhibition of the siphon sensory cells, which can be mimicked by application of the peptide FMRFamide.

Serotonin and cyclic adenosine 3':5'-monophosphate modulate the potassium current in tail sensory neurons in the pleural ganglion of Aplysia [PDF]

The Journal of Neuroscience, 1985
Tail sensory neurons in the pleural ganglion that mediate the afferent portion of the tail withdrawal reflex in Aplysia californica undergo heterosynaptic facilitation of transmitter release during sensitization. As in the siphon sensory neurons, the transmitter serotonin produces facilitation and also elicits a slow, decreased conductance excitatory ...

Age-related deficits in synaptic plasticity rescued by activating PKA or PKC in sensory neurons of Aplysia californica

Frontiers in Aging Neuroscience, 2015
Brain aging is associated with declines in synaptic function that contribute to memory loss, including reduced postsynaptic response to neurotransmitters and decreased neuronal excitability.

An acetylcholine-induced potassium current in tail sensory neurons in the pleural ganglion of Aplysia.

The Japanese Journal of Physiology, 1988
Acetylcholine (ACh) induces a hyperpolarization during current clamp and an outward current during voltage clamp in tail sensory neurons of Aplysia kurodai. This response was proved to be produced by a specific increase in membrane permeability toward potassium ions, the cholinergic antagonists, d-tubocurarine chloride (d-TC), and atropine mildly ...
