“…These and an about 10.5-year component similar to the solar activity cycle had been reported earlier (Halberg et al, 2004). Of interest is the about 200day variation detected with the GOSA software (Czaplicki et al 2006), very close to the 205-day change in spontaneous abortions in Padua reported by Valandro et al (2004), which the authors associate with the extreme lunar perigeal positions, a periodicity of the moon in reaching its greatest distance from the earth, later extended to spontaneous abortions in Nové Zámky (Matuška and Mikulecky, 2006). The aim of this work was to provide biologists and biochemists with an easy-to-use, reliable program capable of finding global minima of an arbitrary function.…”

Transyears in biology have been documented thus far by the extended cosinor approach, including linearnonlinear rhythmometry. We here confirm the existence of transyears by simulated annealing, a method originally developed for a much broader use, but described and introduced herein for validating its application to time series. The method is illustrated both on an artificial test case with known components and on biological data. We provide a table comparing results by the two methods and trust that the procedure will serve the budding sciences of chronobiology (the study of mechanisms underlying biological time structure), chronomics (the mapping of time structures in and around us), and chronobioethics, using the foregoing disciplines to add to concern for illnesses of individuals also a budding focus on diseases of societies, like crime, and of nations and civilizations, like war.

“…The variation in birth rate has been related to the photoperiod or temperature (affecting hormonal concentrations, sperm quality, or sexual activity) and may also be influenced by sociodemographic factors ( Bobak and Gjonca 2001 ). The variation in spontaneous abortions can be influenced by lunar periodicity ( Valandro et al 2004 ).…”

BackgroundThe number of newborn boys was higher than that of girls in the Czech Republic each month from 1950 to 2005. The only exception was November 1986, when the number of newborn boys was significantly reduced. This has been explained by a selective negative impact of the Chernobyl accident in April 1986 on male fetuses during the third month of their prenatal development.ObjectivesThe first and most radioactive cloud passed over the Czech Republic during 30 April–1 May 1986. Concurrent rainfall multiplied the radioactivity by up to > 10,000-fold in specific regions. We verified a hypothesis that the decrease in the male birth fraction in November 1986 correlated with the level of radiation in eight Czech regions after the Chernobyl disaster.ResultsWe found a relationship between the level of radiation and the decrease in the number of newborn boys. The number of newborn boys was decreased in the six eastern regions where the radiation was strongly increased due to rain that accompanied the radioactive cloud. In contrast, the number of newborn boys was not reduced in the two western regions where the radioactivity was markedly lower.ConclusionsA negative impact of radiation on the prenatal population was manifested as a selective loss of newborn boys in November 1986. This loss correlated with level of radioactivity. The 131I probably played the most important role because of its up-take during primary saturation of fetal thyroid by iodine, which accompanies the onset of the gland function in 3-month-old fetuses.

“…Furthermore, lunar cycle has been proved to have an impact on human reproduction, in particular fertility, menstruation and birth rate. Even hospitalized spontaneous abortions are significantly associated with the lunar cycle [6]. Given that the most common cause of spontaneous abortion is chromosomal abnormalities of the embryo, we presume that the lunar cycle could influence the occurrence of chromosomal diseases.…”

Backround: In recent years, there is an increasing number of data supporting the relation between lunar cycle and alterations in human body. For instance, it has been proved that hospitalized spontaneous abortions are significantly associated with the lunar cycle . Given that the most common cause of spontaneous abortion is chromosomal abnormalities of the embryo, we presumed that the lunar cycle could influence the occurrence of chromosomal diseases. From the point of bioethics it is a question if it is applicable to talk with patients about possible impact of cosmobiological factors on their case of chromosomal anomaly. Patients and Methods: We have selected 52 patients, who were bearing a fetus with a prenatally diagnosed chromosomal disorder, which included Down, Turner, Klinefelter, Patau and Edward syndromes. The control group (n=92) consisted of families, that were prenatally tested for chromosomal abnormalities and the results were negative. Then we gathered and analyzed information from patients' medical histories about various factors, which could have predisposed chromosomal disorders: age of both progenitors, consumption of medications during pregnancy, number of miscarriages, number of abortions, cases of genetic disorders in relatives, lunar phase on the day of conception. Results: Lunar phases at the time of conception in the test group distributed as following: new Moon 32.7 percent, first quarter 25.0 percent, full Moon 28.8 percent, third quarter 13.5 percent. In the control group lunar phases distributed as following: new Moon 29.3 percent, first quarter 27.2 percent, full Moon 26.1 percent, third quarter 17.4 percent. There was observed no statistically significant difference between test and control groups (p>0.05). OR for conception with chromosomal anomalies were increased in July (2.7(CI 95% 1.5-4.9) and December (3.2 (CI 95% 1.5-5.2) (p<0.05). OR showed decreased risk for chromosomal anomalies during conception at January (0.3 (CI 95% 0.1-0.7) , April (0.5 (CI 95% 0.2-0.7) and June 0.5 (CI 95% 0.2-0.8) (p<0.05). Conclusions: Our study showed there were no associations between lunar phase at the time of conception with the rates of chromosomal mutations. Conception in July and December increases the risk of chromosomal anomalies during conception. In contrast conception in January, April and June decreases chromosomal anomalies rates.
