Effects of alcohol on sleep parameters of sleep-deprived healthy volunteers

open access: yes, 1997
Both partial and total sleep deprivation frequently result in a rebound of paradoxical sleep (PS), as well as of slow-wave or delta sleep. Acute administration of ethanol inhibits PS in normal volunteers.

Sleep-wake sensitive mechanisms of adenosine release in the basal forebrain of rodents : an in vitro study [PDF]

open access: yes, 2013
Adenosine acting in the basal forebrain is a key mediator of sleep homeostasis. Extracellular adenosine concentrations increase during wakefulness, especially during prolonged wakefulness and lead to increased sleep pressure and subsequent rebound sleep.

Melanin-concentrating hormone (MCH): role in REM sleep and depression

open access: yesFrontiers in Neuroscience, 2015
The melanin-concentrating hormone (MCH) is a peptidergic neuromodulator synthesized by neurons of the lateral hypothalamus and incerto-hypothalamic area. MCHergic neurons project throughout the central nervous system, including areas such as the dorsal (

The role of cognitive processes in sleep disturbance: a comparison of Japanese and English university students

open access: yes, 2002
The present study investigated the role of cognitive processes in the maintenance of clinically significant sleep disturbance across two cultures. A questionnaire was administered to 60 Japanese and 60 English university students to assess the presence ...

The sleep-wakefulness cycle of Wistar rats with spontaneous absence-like epilepsy

open access: yesActa Scientiarum: Biological Sciences, 2015
Possible interactions between the sleep-wakefulness cycle and a new kind of spontaneous epilepsy, expressed as absence-like seizures and spike-wave bursts in FMUSP rats, are evaluated.

Effects of maternal separation on baseline sleep and cold stress-induced sleep rebound in adult Wistar rats

open access: yes, 2004
Study Objectives: To evaluate the influence of early life environments on basal and cold stress-induced sleep patterns in rats.Design: The design was a 3 (Groups [control, early handling, maternal separation]) x 2 (Situations [basal, poststress]) x 11 ...

Effects of paradoxical sleep deprivation on thermoregulation in the rat

open access: yes, 1998
Rats were subjected to chronic paradoxical sleep deprivation (PSD) by the disk-over-water method to determine if they would develop the sustained increase in core (hypothalamic) temperature (T(hy)); elevated temperature set-point (T(set)); and the ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.
