OBJECTIVE
This study investigated whether hospitalised fall-related injuries among young and middle-aged adults were associated with short term effects of alcohol intake, marijuana use and sleep deprivation.
METHODS
A case-crossover design was used to study 690 adults (aged 20 to 64 years) admitted
This study tested whether performance would be more impaired when marijuana use followed partial sleep deprivation (PSD) than when marijuana use followed a typical night of sleep. Seven recreational marijuana users (mean 15 of last 30 days) completed six test sessions in a double-blind randomized
Sleep deprivation (SD) is a common feature in modern society. Prolonged sleep deprivation causes cognition deficits and depression-like behavior in the model of animal experiments. Endocannabinoid system are key modulators of synaptic function, which were related to memory and mood. Although the
Increasing evidence shows the interaction effect of cannabinoids and sleep on cognitive functions. In the present study, we aimed to investigate the interaction effect of cannabinoids type 1 receptor (CB1r) in the CA1 hippocampal region and sleep deprivation (SD) on passive avoidance memory and
A survey of the literature indicates that both rapid eye movement sleep deprivation (RSD) and activation of cannabinoid CB1 receptor (CB1R) may impair novel object recognition (NOR) memory in rodents. To our knowledge, so far, no previous study has investigated the probable
1. Previous work from our laboratory has shown that cannabis induces aggressive behaviour in rats that have been deprived of rapid eye movement (REM) sleep. It was suggested that this effect was related to brain catecholamines, with dopamine playing an agonist role and noradrenaline an inhibitory
Current literature on the effect of cannabis use on sleep quality is mixed, and few studies have used objectively-measured sleep measures or real-time sampling of cannabis use to examine this relationship. The prevalence of cannabis use among older adults and persons living with HIV has increased in
OBJECTIVE
Sleep disturbance is a hallmark feature of cannabis withdrawal. In this study we explored the effects of lithium treatment supplemented with nitrazepam on objective and subjective measures of sleep quality during inpatient cannabis withdrawal.
METHODS
Treatment-seeking cannabis-dependent
OBJECTIVE
To observe the expression of cannabinoid receptor 1 (CB1R) mRNA and pathological changes in rat hippocampus after deprivation of rapid eye movement (REM) sleep.
METHODS
Totally 42 Sprague-Dawley male rats were randomly divided into cage control (CC), tank control (TC) and the sleep
Both nesfatin-1 and cannabinoid systems involved in the regulation of sleep, metabolism, and food intake. The relationship between cannabinoid system and nesfatin-1 levels remains to be elucidated. This study investigated nesfatin-1 and insulin resistance in 72-h rapid eye movement (REM)
Endocannabinoids seem to play a role in the modulation of alertness. Therefore, we measured cannabinoid receptor 1 (CB1R) protein by Western blot and messenger RNA (mRNA) by reverse transcription-polymerase chain reaction in the pons of rats across the 24-h period. We performed evaluations every 4 h
The unsaturated fatty acid amide oleamide (OA), which accumulates in the CSF of rats during sleep deprivation, induces electroencephalographically measured sleep when administered intracerebroventricularly. The mechanism of sleep induction by OA is unclear but may derive from enhancements of GABA or
Sleep is an unavoidable activity of the brain. The delay of the time to sleep (sleep deprivation), induces an increase of slow-wave sleep and rapid-eye-movement (REM) sleep (rebound) once the subject is allowed to sleep. This drive to sleep has been hypothesized to be dependent on the accumulation
The binocular depth inversion illusion (BDII) has been shown to be a sensitive measure of impaired visual information processing under conditions including cannabinoid-intoxicated states, alcohol withdrawal, sleep deprivation, and in patients with positive symptoms of schizophrenia. This study
Cannabinoid type 1 (CB1) receptors are highly expressed in the brain and play a role in behavior control. Endogenous cannabinoid signaling is modulated by high-fat diet (HFD). We investigated the consequences of congenital lack of CB1 receptors on sleep in mice fed standard diet (SD) and HFD. CB1
