However, it is unclear whether melatonin has a protective effect against OSAS-induced cognitive dysfunction in aged individuals and the involved mechanisms are also unclear. Therefore, in the study, the effects of exposure to IH alone and IH in combination with daily melatonin treatment were investigated in C57BL/6 J mice aged 18 months. Assessment of the cognitive ability of mice in a Morris water maze showed that melatonin attenuated IH-induced impairment of learning and memory in aged mice. Enzyme-linked immunosorbent assay, polymerase chain reaction, and western blotting molecular techniques showed that melatonin treatment reduced the levels of the proinflammatory cytokines, interleukin-1β, interleukin-6, and tumor necrosis factor-α, decreased the levels of NOD-like receptor thermal protein domain associated protein 3 and nuclear factor kappa-B, lowered the levels of ionized calcium-binding adapter molecule 1 and glial fibrillary acidic protein, and increased the levels of the synaptic proteins, activity-regulated cytoskeleton-associated protein, growth-associated protein-43, postsynaptic density protein 95, and synaptophysin in IH-exposed mice. Moreover, electrophysiological results showed that melatonin ameliorated the decline in long-term potentiation induced by IH.

We found greater cortisol concentration was further associated with decreased activation in the brain to infant cry in the right precentral gyrus, the left culmen extending into the left inferior temporal gyrus and fusiform, two clusters in the superior temporal gyrus, and in the medial frontal gyrus.

The trials evaluated a range of different psychotherapeutic interventions, oxytocin doses, and mental disorders.

Meta-analysis showed that combined treatment significantly reduced depressive symptoms (d= −1.58, 95 % CI: −3.15 to −0.01). However, the treatment with oxytocin had no significant effects on psychiatric symptoms (d= 0.00, 95 % CI: −0.56–0.57) or social functioning (d = 0.21, 95 % CI: −0.07–0.49).

Various studies have suggested that yoga may reduce both self-reported stress and stress biomarkers, but the evidence for such claims remains inconclusive, especially for yoga styles with a focus on physical postures. In a randomized controlled trial with 98 participants, we therefore examined whether an eight-week Hatha yoga intervention (60 min, 3×/week or more) led to reduced levels of diurnal salivary cortisol (sCort), salivary alpha-amylase (sAA), and subjective momentary stress as compared to a waitlist control group. To ensure the concomitant assessment of self-report and biological measures in an ecologically valid setting, and to capture the diurnal profile of cortisol and alpha-amylase, we employed an ecological momentary assessment approach. Five times per day, participants reported their momentary stress levels on a visual analogue scale and collected saliva samples for the assessment of salivary biomarkers. The intervention led to a significant reduction of subjective momentary stress but there was no change in diurnal sCort or sAA levels. There are several potential explanations for these findings: The intervention may have helped participants to cope better with stress while leaving diurnal levels of stress biomarkers unaffected, or the change may at least not have been reflected in sCort and sAA. Alternatively, there may have been a self-report bias, insofar as a favorable disposition towards yoga may have led participants to report reductions in stress in order to indicate positive effects of the intervention. Our findings contribute to a better understanding of the effects of distinct yoga interventions, demonstrating their potential to serve as low-risk stress relief tools.</div></div>","PeriodicalId":20836,"journal":{"name":"Psychoneuroendocrinology","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
