Abstract
Objective The present study aimed to evaluate the effect of global postural re-education (GPR) on sleep quality and stress in female health science lecturers. Methods A total of 24 female university lecturers were allocated in this randomized controlled trial into intervention (n = 12) and control (n = 12) groups. The intervention group underwent familiarization and training on the therapy to execute an 8-week treatment with GPR. Data collected on sleep quality were analyzed using 24-h accelerometry (Actigraphy GT3X+) in addition to the Pittsburgh Sleep Quality Index (PSQI) questionnaire score as well as the State-Trait Anxiety Inventory (STAI) anxiety questionnaire. Data on stress were collected by measuring salivary cortisol. Results After comparing the GPR of the groups, there was a main effect of the group (F = 5.278, p = 0.044) for PSQI. The post-hoc analysis revealed that both groups decreased scores between pre- and post-treatment. Additionally, post-treatment, there were differences between groups. For sleep latency, there were main effects of group (F = 6.118, p = 0.031) and score × group (F = 9.343, p = 0.011) interactions. The post-hoc analysis revealed that treatment groups decreased scores between pre- and post-treatment, and there were differences between groups (all p < 0.050). Conclusion The self-administered GPR improves sleep quality in female university lecturers, providing a valuable self-regulation tool for enhanced sleep quality and enhanced academic performance. Further study may help to develop this as a potential tool to help university lecturers' job performance.

Revealing the hidden reality of the mammalian 12-h ultradian rhythms. Cell Mol Life Sci 2021; 78:3127-3140. [PMID: 33449146 DOI: 10.1007/s00018-020-03730-5] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 11/18/2020] [Accepted: 12/04/2020] [Indexed: 12/29/2022]
Abstract
Biological oscillations often cycle at different harmonics of the 24-h circadian rhythms, a phenomenon we coined "Musica Universalis" in 2017. Like the circadian rhythm, the 12-h oscillation is also evolutionarily conserved, robust, and has recently gained new traction in the field of chronobiology. Originally thought to be regulated by the circadian clock and/or environmental cues, recent new evidences support the notion that the majority of 12-h rhythms are regulated by a distinct and cell-autonomous pacemaker that includes the unfolded protein response (UPR) transcription factor spliced form of XBP1 (XBP1s). 12-h cycle of XBP1s level in turn transcriptionally generates robust 12-h rhythms of gene expression enriched in the central dogma information flow (CEDIF) pathway. Given the regulatory and functional separation of the 12-h and circadian clocks, in this review, we will focus our attention on the mammalian 12-h pacemaker, and discuss our current understanding of its prevalence, evolutionary origin, regulation, and functional roles in both physiological and pathological processes.

Abstract
OBJECTIVES Recent studies have demonstrated that first-line nurses involved in the coronavirus disease-2019 (COVID-19) crisis may experience sleep disturbances. As breathing relaxation techniques can improve sleep quality, anxiety, and depression, the current study aimed to evaluate the effectiveness of diaphragmatic breathing relaxation training (DBRT) for improving sleep quality among nurses in Wuhan, China during the COVID-19 outbreak. METHODS This study used a quasi-experimental (before and after) intervention strategy, with 151 first-line nurses from four wards in Leishenshan hospital. The Pittsburgh Sleep Quality Index (PSQI), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) to evaluate the effectiveness of DBRT before and after the intervention. Data were examined using the Shapiro-Wilk test, Levene's test, and paired t-test. RESULTS A total of 140 nurses completed the DBRT sessions. First-line nurses achieved significant reductions in global sleep quality (p < 0.01), subjective sleep quality (p < 0.001), sleep latency (p < 0.01), sleep duration (p < 0.001), sleep disturbances (p < 0.001), habitual sleep efficiency (p = 0.015), daytime dysfunction (p = 0.001), and anxiety (p = 0.001). There were no significant reductions in the use of sleeping medication (p = 0.134) and depression (p = 0.359). CONCLUSION DBRT is a useful non-pharmacological treatment for improving sleep quality and reducing anxiety among first-line nurses involved in the COVID-19 outbreak. The study protocol was clinically registered by the Chinese Clinical Trial Registry. CLINICAL TRIAL REGISTRATION NUMBER ChiCTR2000032743.

Abstract
Background: Breathing is an essential part of life. Diaphragmatic breathing (DB) is slow and deep breathing that affects the brain and the cardiovascular, respiratory, and gastrointestinal systems through the modulation of autonomic nervous functions. However, the effects of DB on human health need to be further investigated. Methods: The author conducted a PubMed search regarding the current evidence of the effect of DB on health. Results: This review consists of a total of 10 systematic reviews and 15 randomized controlled trials (RCTs). DB appears to be effective for improving the exercise capacity and respiratory function in patients with chronic obstructive pulmonary disease (COPD). Although the effect of DB on the quality of life (QoL) of patients with asthma needs to be investigated, it may also help in reducing stress; treating eating disorders, chronic functional constipation, hypertension, migraine, and anxiety; and improving the QoL of patients with cancer and gastroesophageal reflux disease (GERD) and the cardiorespiratory fitness of patients with heart failure. Conclusions: Based on this narrative review, the exact usefulness of DB in clinical practice is unclear due to the poor quality of studies. However, it may be a feasible and practical treatment method for various disorders.

Abstract
Contemplative practices, such as meditation and yoga, are increasingly popular among the general public and as topics of research. Beneficial effects associated with these practices have been found on physical health, mental health and cognitive performance. However, studies and theories that clarify the underlying mechanisms are lacking or scarce. This theoretical review aims to address and compensate this scarcity. We will show that various contemplative activities have in common that breathing is regulated or attentively guided. This respiratory discipline in turn could parsimoniously explain the physical and mental benefits of contemplative activities through changes in autonomic balance. We propose a neurophysiological model that explains how these specific respiration styles could operate, by phasically and tonically stimulating the vagal nerve: respiratory vagal nerve stimulation (rVNS). The vagal nerve, as a proponent of the parasympathetic nervous system (PNS), is the prime candidate in explaining the effects of contemplative practices on health, mental health and cognition. We will discuss implications and limitations of our model.

Abstract
OBJECTIVES To evaluate whether the application of a relaxation therapy reduces the blood pressure in hypertensive patients and whether there is improvement in several parameters which can influence blood pressure such as anxiety, quality of life and sleep. METHODS A quasi-experimental study (measures before-after) was performed in 25 Primary Care patients with hypertension poorly controlled by pharmacological treatment. The intervention consisted of relaxation therapy composed of 3techniques: passive relaxation of Schwartz-Haynes, diaphragmatic breathing and imaginary visualization. A total of 14 group sessions of 30min each (2/week) were conducted. Systolic and diastolic blood pressure were taken at the beginning and end of the relaxation programme implemented and after each of the programme sessions. The Pittsburgh Sleep Quality, Quality of Life Hypertension, State-Trait Anxiety and Perceived Stress questionnaires were used to measure psychosocial parameters. RESULTS After intervention, a reduction in systolic blood pressure of 20mmHg (p<.001) and of 8mmHg (p<.001) in diastolic blood pressure was observed. Regarding other factors, sleep quality (p<.001), quality of life (p<.001) and state anxiety (p=.004) were significantly improved. CONCLUSIONS Relaxation therapy had positive effects in improving blood pressure parameters, as well as the other factors evaluated. In our opinion, such strategies should be evaluated more thoroughly to consider their inclusion in Primary Care.

Abstract
"Musica universalis" is an ancient philosophical concept claiming the movements of celestial bodies follow mathematical equations and resonate to produce an inaudible harmony of music, and the harmonious sounds that humans make were an approximation of this larger harmony of the universe. Besides music, electromagnetic waves such as light and electric signals also are presented as harmonic resonances. Despite the seemingly universal theme of harmonic resonance in various disciplines, it was not until recently that the same harmonic resonance was discovered also to exist in biological systems. Contrary to traditional belief that a biological system is either at stead-state or cycles with a single frequency, it is now appreciated that most biological systems have no homeostatic "set point," but rather oscillate as composite rhythms consisting of superimposed oscillations. These oscillations often cycle at different harmonics of the circadian rhythm, and among these, the ~12-hour oscillation is most prevalent. In this review, we focus on these 12-hour oscillations, with special attention to their evolutionary origin, regulation, and functions in mammals, as well as their relationship to the circadian rhythm. We further discuss the potential roles of the 12-hour clock in regulating hepatic steatosis, aging, and the possibility of 12-hour clock-based chronotherapy. Finally, we posit that biological rhythms are also musica universalis: whereas the circadian rhythm is synchronized to the 24-hour light/dark cycle coinciding with the Earth's rotation, the mammalian 12-hour clock may have evolved from the circatidal clock, which is entrained by the 12-hour tidal cues orchestrated by the moon.

Abstract
Blood pressure (BP) varies based on genetic and environmental factors. To test genetic and environmental influences on body weight (BW) and BP, one-cell homozygous embryos were transferred into spontaneously hypertensive (SHR, pup:shr) or (Wistar-Kyoto normotensive [WKY], pup:wky) normotensive rats' oviducts (embryos: s,w; oviduct-uterine: S,W), cross-suckled at birth (nurses S,W) and weaned to normal diets at day-21. BP at day-120 was measured by radiotelemetry and analyzed by methods of linear least square rhythmometry and analysis of variance. Genetics dominantly affected shr BP, causing it to be significantly higher at birth (24.6 ± 1.8 in sS versus 21.8 ± 1.7 mmHg in wW, P < 0.005), and at day-120 (198 ± 0.5 in sSS versus 127 ± 0.2 mmHg in wWW, P < 0.001), with lower BW than those of wky (5.3 ± 0.2 versus 5.7 ± 0.2 g at birth, 332 ± 5 versus 404 ± 6 g at day-120, both P < 0.001). Surprisingly, uterine-suckling milieus lowered shr BP significantly at day-120 (198 ± 0.5 in sSS versus 178 ± 0.5, 147 ± 0.6, 179 ± 0.5 mmHg in sSW, sWS, sWW, respectively, all P < 0.01). BP was slightly elevated when wky-genetics were implanted into the S-uterine by 4 mmHg (wSW, P < 0.05), whereas implanting shr embryos into the W-uterine environment (sWS) lowered BP by 51 mmHg (P < 0.001). In summary, the hypertensive shr-strain showed significantly lower BP when provided with an WKY-uterine environment and/or by WKY-nursing mothers, indicating that environment can modify genetic influences; yet the shr MESORs (rhythm-adjusted 24-h mean: midline estimating statistic of rhythm) lowered by WKY environments remained above MESORs encountered in wky-donors.
