The Effect of Porcine Orexin a on Glucose-Dependent Insulinotropic Polypeptide Plasma Concentrations in Pigs

open access: yesEuropean Journal of Inflammation, 2010
The orexigenic system was discovered in 1998. It consists of two neuropeptides, Orexin A and Orexin B. Researchers have focused more on Orexin A, since its intracerebroventricular injection into the lateral ventricle of the rat's brain causes an increase

Excessive daytime sleepiness and frequent nightmares are associated with suicidal ideation among psychiatric inpatients

open access: yesSleep Research, Volume 3, Issue 2, Page 161-169, June 2026.
Abstract Objectives This study aimed to explore the association between excessive daytime sleepiness (EDS) and frequent nightmares and the risk for suicidal ideation (SI) among psychiatric inpatients. Methods In this cross‐sectional study, 650 inpatients were consecutively recruited from the inpatient department of Shantou University Mental Health ...

Reactivation of hyperglycemia-induced hypocretin (HCRT) gene silencing by N-acetyl-d-mannosamine in the orexin neurons derived from human iPS cells

open access: yesEpigenetics, 2017
Orexin neurons regulate critical brain activities for controlling sleep, eating, emotions, and metabolism, and impaired orexin neuron function results in several neurologic disorders.

Orexin and Alzheimer’s Disease

open access: yes, 2016
Alzheimer's disease (AD) is the most frequent age-related dementia. It prevalently causes cognitive decline, although it is frequently associated with secondary behavioral disturbances. AD neurodegeneration characteristically produces a remarkable destruction of the sleep-wake cycle, with diurnal napping, nighttime arousals, sleep fragmentation, and ...

Machine Learning for Diagnosis and Differentiation of Central Disorders of Hypersomnolence: A Systematic Review

open access: yesEuropean Journal of Neurology, Volume 33, Issue 6, June 2026.
This graphical abstract presents the review process (including 41 studies). It highlights the use of machine learning techniques in adults with CDH, such as unsupervised learning for phenotype discovery and supervised learning for diagnosis classification. The figure summarizes the strengths and limitations of each approach, along with key clinical and

A Meta‐Analysis of the Effects of Acute Sleep Deprivation on the Cortical Transcriptome in Rodent Models

open access: yesJournal of Sleep Research, Volume 35, Issue 3, June 2026.
How does sleep deprivation affect the brain? We performed a meta‐analysis of publicly available transcriptional profiling datasets characterising the effects of sleep deprivation on cortical gene expression (n = 293 mice, 16,290 genes) and validated our results in an independent sample (n = 222 mice).
