Because paradoxical sleep deprivation (PSD) induces a catabolic hormone profile, we sought to evaluate the morphology of tibialis anterior (TA) muscle and testosterone corticosterone levels sleep-deprived rats.Three study groups rats were established: first group was deprived for 96 h; second also h, but then returned their home-cage allowed next third control group, with normal cycle.PSD reduced weight fiber cross-sectional area TA muscle. Moreover, PSD enhanced plasma serum levels. The h...
ABSTRACT Purpose Sleep is considered essential for muscle recovery, mainly due to its effect on hormone secretion. Total sleep deprivation or restriction known alter not only blood hormones but also cytokines that might be related skeletal recovery. This study aimed evaluate whether total after eccentric exercise-induced damage (EEIMD) modifies the profiles of and cytokines. Methods In two separate conditions, with a crossover randomized model, 10 men (age, 24.5 ± 2.9 yr; body mass index,...
Sleep deprivation (SD) can induce muscle atrophy. We aimed to investigate the changes underpinning SD-induced atrophy and impact of this condition on rats that were previously submitted resistance training (RT). Adult male Wistar EPM-1 randomly allocated into 1 5 groups: control, sham, SD (for 96 h), RT, RT+SD. The major outcomes study fiber cross-sectional area (CSA), anabolic catabolic hormone profiles, abundance select proteins involved in protein synthesis degradation pathways. resulted...
The aim was observe the influence of sleep deprivation (SD) and recovery on muscle regeneration process in rats submitted to cryolesion.Thirty-two Wistar were randomly allocated four groups: control (CTL), SD for 96 h (SD96), plus period (CTL + R) SD96h (SD96 R). animals injury by cryolesioning, after recovery.The major outcomes this study reduction muscular IGF-1 both legs (injured uninjured) a delay compared that slept, with increase connective tissue, inflammatory infiltrate minor...
Sleep is important for maintenance of skeletal muscle health. debt can induce atrophy by increasing glucocorticoids and decreasing testosterone, growth hormone insulin-like factor-I. These hormonal alterations result in a highly proteolytic environment characterized decreased protein synthesis increased degradation. Given that sleep deprivation increasingly prevalent modern society, strategies to minimize or reverse its adverse effects need be investigated. Resistance exercise has been...
Obstructive sleep apnoea (OSA) is positively associated with cardiometabolic diseases; however, high levels of physical activity could decrease the incidence OSA and comorbidities. In this study we aimed to examine in relation activity, its role as a protective factor individuals on diseases, an 8–9-year follow-up study. We analysed data 658 volunteers from São Paulo Epidemiologic Sleep Study (EPISONO), cohort aged 20–80 years, collected through polysomnography, International Physical...
Objective. Describe multicompartmental changes in the fat and various muscle fiber types, as well hormonal profile metabolic rate induced by SD rats. Methods. Twenty adult male Wistar rats were equally distributed into two groups: experimental group (EG) control (CG). The EG was submitted to for 96 h. Blood levels of corticosterone (CORT), total testosterone (TESTO), insulin like growth factor-1 (IGF-1), thyroid hormones (T3 T4) used assess catabolic environment. Muscle trophism measured...
The World Health Organization declared the new coronavirus disease, COVID-19, an international public health emergency concern.Governments in various countries have taken several protective measures to limit exposure virus, such as closing borders and schools, cancelling travel, issuing travel warnings, providing guidance about working from home social distancing. 1 first line of care for those who are possibly infected is conducted by professionals extend incredible effort attend...
OBJECTIVE:To assess the effect of passive body heating on sleep patterns patients with fibromyalgia.METHODS: Six menopausal women diagnosed fibromyalgia according to criteria determined by American College Rheumatology were included.All underwent immersion in a warm bath at temperature 36¡1 ˚C for 15 sessions 30 minutes each over period three weeks.Their assessed polysomnography following time-points: pre-intervention (baseline), first day intervention (acute), last (chronic), and weeks...
Paradoxical sleep deprivation activates the sympathetic nervous system and hypothalamus-pituitary-adrenal axis, subsequently interfering with cardiovascular system. The beneficial effects of resistance training are related to hemodynamic, metabolic hormonal homeostasis. We hypothesized that can prevent cardiac remodeling dysfunction caused by paradoxical deprivation.Male Wistar rats were distributed into four groups: control (C), (RT), for 96 hours (PSD96) both (RT/PSD96). Doppler...
INTRODUCTION: Sleepiness is responsible for a considerable proportion of traffic accidents. It thus an important safety issue to find robust, objective and practical way estimate the amount time person has been awake. To attempt meet this goal, we investigated relationship between sleepiness posture control. METHODS: Subjects were kept awake 36 hours posturographic data during quiet standing collected every two by means force platform. The surface (rigid or foam surface) visual (eyes open...
The aim of the study was to Janus kinase/tyrosine kinase-activated transduction factor (JAK/STAT) signaling pathway and myogenesis on masseter muscle after sleep deprivation investigate role stress in this scenario.A total 18 male Wistar rats were divided into following groups: control (n = 6): animals not submitted any procedures, paradoxical vehicle (PSD + V; n subjected PSD for 96 h MET; with administration metyrapone. Paradoxical performed by modified multiple platforms method....
Abstract The aim of this study was to evaluate the Toll like signaling pathway and atrophy after sleep deprivation (SD) in rat masticatory muscles: masseter temporal. A total 24 animals distributed into three groups: Control group (CTL, n = 8), subjected SD for 96 h (SD96, 8) more recovery (SD96 + R, 8). Histopathological analysis revealed presence acute inflammatory cells, congested vessels, fibrosis, high cellularity skeletal muscle fibers from temporal submitted SD. These morphological...
Abstract Background The aim of this study was to evaluate whether sleep deprivation (SD) induces inflammation, autophagy and myogenesis in the following masticatory muscles: masseter temporal. Methods In study, 18 animals were randomly distributed into three groups: control group (CTL, n = 6), SD for 96 hours (SD96, more recovery (SD96 + R, 6). Results histopathological analysis, able induce inflammation Nevertheless, lack inflammatory process evidenced SD96 R. Upregulation TNF‐alpha...
Obesity is one of the modifiable risk factors for dementia. Insulin resistance, abundance advanced glycated end-products, and inflammation are some mechanisms associated with lower cognitive performance observed in obesity. This study aims to evaluate function subjects distinct degrees obesity, comparing class I II obesity (OBI/II) III (OBIII), investigate metabolic markers that can distinguish OBIII from OBI/II. Study Design. a cross-sectional study, which 45 females BMI varying 32.8 51.9...
Objective To analyze the effects of androgen therapy on thyroarytenoid (TA) muscle, expression receptors (ARs) and hyaluronic acid (HA) concentration in vocal folds (VFs) adult female rats. Methods Twenty‐one Wistar rats were divided into experimental control groups. The group received weekly intramuscular injections nandrolone decanoate for 9 weeks. Following euthanasia dissection VFs, histomorphometric analysis TA immunohistochemical evaluation ARs, measurement HA using ELISA‐like...

Infertility affects about 8 to 12% of couples childbearing age around the world, and is recognized as a global public health issue by WHO. From psychosocial perspective, infertile individuals experience intense psychological distress, related emotional disorders, which have repercussions on marital social relationships. The symptoms persist even after seeking specialized treatment, such assisted reproductive technologies (ART). While stress impact ART outcome has been comprehensively...
Abstract Objective Neuroscience research using laboratory animals has increased over the years for a number of reasons. Some these studies require use anesthetics surgical procedures. However, promotes several physiological changes that may interfere with experimental results. Although and methods delivery used to vary, one most common is ketamine associated another compound such as xylazine. We aimed evaluate effect xylazine (KX) on corticosterone levels degree phosphorylation p44/42...
