Introduction The relationship between the moon's cycles and menses is so fundamental that the two phenomena are reiated linguistically. The terms 'moon' and 'menstruation' share the same Latin or Greek root, m-, meaning 'to measure,' Various world religions and cuitures have acknowledged the bond between women and the moon. Traditional Chinese Medicine links the moon with the feminine, or yin p...
There is a popular belief that the lunar cycle influences spontaneous delivery in both humans and cattle. To assess this relationship, we investigated the synodic distribution of spontaneous deliveries in domestic Holstein cows. We used retrospective data from 428 spontaneous, full-term deliveries within a three-year period derived from the calving records of a private farm in Hokkaido, Japan. ...
Sir, On the basis of the data that they had collected, Parmeshwaran et al.(1999) concluded that a significant relationship exists between phases of the lunar synodic cycle and the development of psychiatric morbidity. From a methodological perspective, I have a reservation about their validity of their conclusions : Parmeshwaran et al.(1999) studied patients at the time of admission and not at ...
Lunar cycle-associated physiology has been found in a wide variety of organisms. Studies suggest the presence of a circalunar clock in some animals, but the location of the lunar clock is unclear. We previously found lunar-associated expression of transcripts for Cryptochrome3 gene (SgCry3) in the brain of a lunar phase-responsive fish, the Goldlined spinefoot (Siganus guttatus). Then we propos...
Reproduction in iteroparous marine organisms is often timed with abiotic cycles and may follow lunar, tidal amplitude, or daily cycles. Among intertidal marine invertebrates, decapods are well known to time larval release to coincide with large amplitude nighttime tides, which minimizes the risk of predation. Such bimonthly cycles have been reported for few other intertidal invertebrates. We do...
OBJECTIVES Popular belief holds that the lunar cycle affects human physiology, behavior, and health, including sleep. To date, only a few and conflicting analyses have been published about the association between lunar phases and sleep. Our aim was to analyze the relationship between lunar phases and sleep characteristics. METHODS In this retrospective, cross-sectional analysis, data from 319...
Popular belief holds that the lunar cycle affects human physiology, behaviour and health. We examined the influence of moon phase on sleep duration in a secondary analysis of a feasibility study of mobile telephone base stations and sleep quality. We studied 31 volunteers (18 women and 13 men, mean age 50 years) from a suburban area of Switzerland longitudinally over 6 weeks, including two full...
[14C]glycine uptake by scales in vitro was measured in coho salmon (Oncorhynchus kisutch Walbaum) smolts at different times during several semi-lunar cycles. There was a clear cyclical pattern of glycine uptake during the semi-lunar period. Evidence for semi-lunar cycles of liver and muscle RNA:DNA ratios, carcass water content, haematocrit, and plasma triglyceride, glucose and cholesterol leve...
Figure 1: Location of lunar landing sites and the Apollo passive seismometer network. INTRODUCTION Geophysical observations of the Moon via a global and long-lived network of stations will yield a wealth of knowledge from regions heretofore inaccessible using the Apollo database. Data collected over a period of at least 6 years (covering one lunar tidal cycle) will yield information on the natu...
