Atrophy of the Vagus Nerve in Parkinson's Disease Revealed by High-Resolution Ultrasonography

Frontiers in Neurology, 2018
Background: The vagus nerve has been suggested to represent one major route of disease progression in Parkinson's disease (PD). Here, we examined whether patients with idiopathic PD exhibit an atrophy of the vagus nerve in comparison to age-matched ...

Development and characterization of a chronic implant mouse model for vagus nerve stimulation

eLife, 2021
Vagus nerve stimulation (VNS) suppresses inflammation and autoimmune diseases in preclinical and clinical studies. The underlying molecular, neurological, and anatomical mechanisms have been well characterized using acute electrophysiological stimulation

Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron‐Mediated Lung‐to‐Brain Axis

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSC) are considered a promising alternative for neuropathic pain (NP) treatment, but underlying mechanisms remain elusive. Huang et al. illustrate that a Npy2r sensory neuron‐related lung–brain axis contributes to MSC analgesia.

Ipsilateral vagotomy to unilaterally ovariectomized pre-pubertal rats modifies compensatory ovarian responses

Reproductive Biology and Endocrinology, 2007
The present study evaluates the participation of the vagus nerve in pre-pubertal rats with unilateral ovariectomy on puberty onset, and on progesterone, testosterone and estradiol serum levels, and the compensatory responses of the ovary.

Vagus nerve stimulation boosts the drive to work for rewards

Nature Communications, 2020
Interoceptive feedback transmitted via the vagus nerve plays a vital role in motivation by tuning actions according to physiological needs. Whereas vagus nerve stimulation (VNS) reinforces actions in animals, motivational effects elicited by VNS in ...

Fluorescence Guided Surgery in Gastric Cancer: What Do We Have and What Can We Do?

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background and Objective Fluorescence imaging has emerged as a valuable adjunct in gastric surgery, enhancing resection precision and oncologic outcomes. However, the use of indocyanine green (ICG) remains controversial due to uncertainties in efficacy and administration. A lack of standardized protocols persists.

Ultrasonography of the Vagus Nerve in Parkinson's Disease

Frontiers in Neurology, 2018
Based on the topographic distribution of α-synuclein-enriched Lewy bodies, it has been hypothesized that Parkinson's disease may start in the gastrointestinal tract and gain access to the central nervous system via the vagus nerve.

Transcutaneous Vagus Nerve Stimulation [PDF]

European Neurological Review, 2011
Invasive vagus nerve stimulation (VNS) is an approved treatment for drug-resistant epilepsy. Besides its recognised clinical efficacy, there are major drawbacks, such as invasiveness and a great many side effects. Therefore there is a medical demand for transcutaneous VNS (t-VNS®), which combines selective, non-invasive access to vagus nerve afferents ...

Gastric Distension Index: A Novel Radiographic Marker Associated With Postoperative Gastric Stasis After Gastrectomy

Annals of Gastroenterological Surgery, EarlyView.
This study introduces the Hiki Index (HI), a novel radiographic metric based on upright abdominal X‐rays, to objectively assess postoperative gastric dilatation after gastrectomy. The HI demonstrated strong predictive value for gastrointestinal symptoms and the need for therapeutic intervention, offering a practical tool for early detection and ...

Vagus nerve stimulation in cerebral stroke: biological mechanisms, therapeutic modalities, clinical applications, and future directions

Neural Regeneration Research
Stroke is a major disorder of the central nervous system that poses a serious threat to human life and quality of life. Many stroke victims are left with long-term neurological dysfunction, which adversely affects the well-being of the individual and the
