Extreme late chronotypes and social jetlag challenged by Antarctic conditions in a population of university students from Uruguay
Publication date: Available online 15 January 2016 Source:Sleep Science Author(s): Bettina Tassino, Stefany Horta, Noelia Santana, Rosa Levandovski, Ana Silva In humans, a person’s chronotype depends on environmental cues and on individual characteristics, with late chronotypes prevailing in youth. Social jetlag (SJL), the misalignment between an individual׳s biological clock and social time, is higher in late chronotypes. Strong SJL is expected in Uruguayan university students with morning class schedules and very late entertainment activities. Sleep disorders have been reported in Antarctic inhabitants, ...

Caffeine intake has no effect on sleep quality in community dwellers living in a rural Ecuadorian village (The Atahualpa Project)
Publication date: Available online 4 January 2016 Source:Sleep Science Author(s): Oscar H. Del Brutto, Robertino M. Mera, Mauricio Zambrano, Pablo R. Castillo More information is needed to better understand the effect of caffeine on sleep quality at the community level. In a population-based, cross-sectional study design, we aimed to assess the effect of caffeine intake on sleep quality by the use of a multivariate exposure-effect model, adjusted for relevant confounders. All Atahualpa residents aged ≥40 years were identified during a door-to-door survey and interviewed with the Pittsburgh Sleep Quality Index...

Immunomodulation by classical conditioning in NZB/W (F1) mice: Lifespan and diurnal variation
Publication date: Available online 4 January 2016 Source:Sleep Science Author(s): Mario André Leocadiô Miguel, Luiz Menna-Barreto Systemic Lupus Eritematosus (SLE) is a systemic inflammatory disease often treated with the agent cyclophosphamide (CY), known by provoking important adverse reactions to the organism. Ader and Cohen have demonstrated an alternative way of administrating this agent based on pavlovian conditioning, in order to reduce the aggression caused by CY. Considering the influence of the temporal organization on learning and memory processes, the purpose of this study was to understand the tempor...

REM sleep deprivation promotes a dopaminergic influence in the striatal MT2 anxiolytic-like effects
Publication date: Available online 10 November 2015 Source:Sleep Science Author(s): Ana Carolina D. Noseda, Adriano D.S. Targa, Lais S. Rodrigues, Mariana F. Aurich, Marcelo M.S. Lima The aim of this study was to investigate the possible anxiolytic-like effects of striatal MT2 activation, and its counteraction induced by the selective blockade of this receptor. Furthermore, we analyzed this condition under the paradigm of rapid eye movement (REM) sleep deprivation (REMSD) and the animal model of Parkinson’s disease (PD) induced by rotenone. Male Wistar rats were infused with intranigral rotenone (12μg/μL)...

Sleep quality and the treatment of intestinal microbiota imbalance in Chronic Fatigue Syndrome: A pilot study
This study builds on recent evidence that sleep may be influenced by gut microbiota, by assessing whether changes to microbiota in a clinical population known to have both poor sleep and high rates of colonization with gram-positive faecal Streptococcus, can improve sleep. Twenty-one CFS participants completed a 22-day open label trial. Faecal microbiota analysis was performed at baseline and at the end of the trial. Participants were administered erythromycin 400mg b.d. for 6 days. Actigraphy and questionnaires were used to monitor sleep, symptoms and mood. Changes in patients who showed a clinically significant change in...

Pedunculopontine arousal system physiology—Effects of psychostimulant abuse
Publication date: Available online 10 October 2015 Source:Sleep Science Author(s): Francisco J. Urbano, Verónica Bisagno, Betina González, María Celeste Rivero-Echeto, Javier A. Muñiz, Brennon Luster, Stasia D’Onofrio, Susan Mahaffey, Edgar Garcia-Rill This review describes the interactions between the pedunculopontine nucleus (PPN), the ventral tegmental area (VTA), and the thalamocortical system. Experiments using modulators of cholinergic receptors in the PPN clarified its role on psychostimulant-induced locomotion. PPN activation was found to be involved in the animal’s voluntary search fo...

Interactions between sleep, stress, and metabolism: From physiological to pathological conditions
Publication date: Available online 28 September 2015 Source:Sleep Science Author(s): Camila Hirotsu, Sergio Tufik, Monica Levy Andersen Poor sleep quality due to sleep disorders and sleep loss is highly prevalent in the modern society. Underlying mechanisms show that stress is involved in the relationship between sleep and metabolism through hypothalamic–pituitary–adrenal (HPA) axis activation. Sleep deprivation and sleep disorders are associated with maladaptive changes in the HPA axis, leading to neuroendocrine dysregulation. Excess of glucocorticoids increase glucose and insulin and decrease adiponectin le...

Pedunculopontine arousal system physiology – Deep brain stimulation (DBS)
Publication date: Available online 25 September 2015 Source:Sleep Science Author(s): Edgar Garcia-Rill, Brennon Luster, Stasia D’Onofrio, Susan Mahaffey, Veronica Bisagno, Francisco J. Urbano This review describes the wake/sleep symptoms present in Parkinson׳s disease, and the role of the pedunculopontine nucleus in these symptoms. The physiology of PPN cells is important not only because it is a major element of the reticular activating system, but also because it is a novel target for deep brain stimulation in the treatment of gait and postural deficits in Parkinson׳s disease. A greater understanding ...

The role of flow limitation as an important diagnostic tool and clinical finding in mild sleep-disordered breathing
Publication date: Available online 3 September 2015 Source:Sleep Science Author(s): Nevin Arora, Gerard Meskill, Christian Guilleminault Obstructive sleep apnea (OSA) is defined by quantifying apneas and hypopneas along with symptoms suggesting sleep disruption. Subtler forms of sleep-disordered breathing can be missed when this criteria is used. Newer technologies allow for non-invasive detection of flow limitation, however consensus classification is needed. Subjects with flow limitation demonstrate electroencephalogram changes and clinical symptoms indicating sleep fragmentation. Flow limitation may be increas...

Urinary proteomic profiling in severe obesity and obstructive sleep apnoea with CPAP treatment
Conclusions The urinary proteome is compared in OSA with CPAP and without OSA in severe obesity. The effects of CPAP on OSA may lead to changes in the urinary peptides but further research work is needed to investigate the potential role for urinary proteomics in characterising urinary peptide profiles in OSA.
