They completed Profile of Mood States questionnaires and performed exhaustive extreme intensity cycle ergometer tests (310 ± 70 W) before, and on three consecutive days following, one night’s sleep loss. Mean time to exhaustion was not affected by sleep loss. Mean total mood state disturbance was elevated on days 1 and 2 after sleep loss compared to baseline. There were strong correlations (r > 0.82) between individual changes (day 1 minus baseline, day 2 minus baseline, day 3 minus baseline) in time to exhaustion and individual changes in mood state: changes in time to exhaustion were associated with changes in the fatigue subscore on day 1; with changes in the vigour subscore on day 2, and with changes in the fatigue subscore on day 3. These results demonstrate a relationship, which may or may not reflect causality, between mood state and performance.","PeriodicalId":9208,"journal":{"name":"Biological Rhythm Research","volume":"53 1","pages":"1801 - 1810"},"PeriodicalIF":1.1,"publicationDate":"2022-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47427719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of photoperiod variation on the immune and antioxidant status and their possible correlation with different tissues have not been reported in Dybowski’s frog, Rana dybowskii. In this study, the specific activities of immune and antioxidant enzymes in R. dybowskii under different photoperiods were evaluated. The results demonstrated that the photoperiod significantly impacted antioxidant enzymes and immune enzymes in Dybowski’s frog. In terms of antioxidant enzyme activity, catalase (CAT) and superoxide dismutase (SOD) activities in frogs at 6 L:18D and 0 L:24D were significantly higher than those at 18 L:6D and 24 L:0D, respectively. Further, the activities of these enzymes increased during the dark phase and decreased during the light phase. The malondialdehyde (MDA) content decreased significantly with the decrease in photoperiod time. Lysozyme (LZM) activity in serum and the liver decreased with a prolonged photoperiod. LZM activity in the dark cycle was higher, but the peak activity in skin occurred at noon. Thus, long-term light exposure may cause oxidative stress in Dybowski’s frog. Accordingly, a 6 L:18D photoperiod may be suitable for optimum physiological functions of this species.","PeriodicalId":9208,"journal":{"name":"Biological Rhythm Research","volume":"53 1","pages":"1790 - 1799"},"PeriodicalIF":1.1,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48496758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nine athletes were requested to answer the MCTQ questionnaire and monitor their core temperature during night. In the MCTQ, the midpoint of sleep on free day, which is corrected for sleep debt accumulated during the workweek (MSFsc), was calculated. The core temperature was monitored using a telemetric system with an ingestible capsule-type sensor. The correlation between the MSFsc and the time at the lowest core temperature was examined. The range of MSFsc and time at minimum core temperature were 2.54–7.75 (mean ±SE: 4.54 ± 0.52, 95%CI: 3.52–5.55) and 3:43–7:41 (mean ±SE: 5:24 ± 0:32, 95%CI: 4:21–6:27), respectively. Four participants with their MSFsc later than 4.96 showed times at minimum core temperature later than 6:00. A significant correlation between the MSFsc and time at minimum core temperature was observed, with a very high correlation coefficient (r = 0.86, p < 0.01). These results suggest that the MSFsc may be useful to find athletes who have a better chance to advance their circadian rhythmicity for morning competitions.","PeriodicalId":9208,"journal":{"name":"Biological Rhythm Research","volume":"53 1","pages":"1782 - 1789"},"PeriodicalIF":1.1,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45040607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individuals with balanced, future, and past positive time perspective had better sleep characteristics, and were less likely to exhibit symptoms of depression. Persons with past negative, present hedonistic and present fatalistic time perspective were more likely to have worse sleep characteristics, and exhibited signs of depression.

To combat the pandemic, lockdown has been imposed worldwide, the impact of which, and, the subsequent new normal phase has raised global concern. Two workforces of the Indian population, rural agrarian and urban corporate, were compared for impact on sleep quality, depressive symptomatology, screen exposure, somatic pain and other health co-morbidities in three-time frames – prior, during and post lockdown periods. An online survey was conducted for those engaged in the urban corporate sector (N=146) and an interview for the rural agrarian workforce (N=100). Both the workforces had adumbrated significant (p<0.05) variations in sleep behavior with changes noted in sleep latency and feeling of sleepiness, being higher during the lockdown phase. The screen time had also been identified to be positively related to the presence of depressive symptomatology and negatively with sleep duration among both the workforces. Our findings suggest that COVID-19 induced lockdown affects the urban corporate more with erratic sleep behavior, enhanced psychometric distress, somatic discomfort and behavioral modifications that might be due to social isolation, reliance over digital use, and disoriented work schedule .","PeriodicalId":9208,"journal":{"name":"Biological Rhythm Research","volume":"53 1","pages":"1753 - 1769"},"PeriodicalIF":1.1,"publicationDate":"2022-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41446524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the typical circadian markers, changes in melatonin (MLT), and core body temperature (CBT) are difficult to measure 24-hour cycle of daily life. In this study, to propose relatively easy-to-monitor cardiac rhythmicity-related indicators as circadian markers, the biomarkers, including MLT, CBT, heart rate (HR), and heart rate variability (HRV), were collected from 22 Korean men. The MLT and CBT showed the largest positive correlation with R wave-to-R wave (RR) interval (Pearson’s r = .620, p < .001) and HR (Pearson’s r = .476, p < .001), respectively. In addition, the difference between the peak times of the seventh-order fitted MLT (adjusted R2 = .960, peak time 04:56) and RR interval (adjusted R2 = .960, peak time 04:35) was approximately 21 min; especially, the nadir times of the fitted CBT (adjusted R2 = .961, nadir time 04:55) and HR (adjusted R2 = .934, nadir time 04:52) were almost the same. Therefore, we can confidently say that HR and RR intervals are good indicators for estimating an individual’s circadian rhythm.","PeriodicalId":9208,"journal":{"name":"Biological Rhythm Research","volume":"53 1","pages":"1735 - 1752"},"PeriodicalIF":1.1,"publicationDate":"2022-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47252875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological clocks are composed of specific molecules (clock genes) that interact with cells throughout the body and are the timing devices that organisms use to regulate circadian rhythms. Circadian rhythms have been observed in the human gastrointestinal tract. To this end, basal gastric acid production, epithelial cell proliferation, gastrointestinal motility and appetite regulation vary with the time of day. The abnormal expression of clock genes can alter normal circadian rhythms and subsequently cause a variety of illnesses, including cancers.
