The Effect of Saffron (<i>Crocus sativus L. Iridaceae</i>) Orally Administration on Blood Level of Sex Hormones in Rats

“…In this case, the level of FSH was 0.7 ± 0.04 IUL/L in the 1st controls vs 1.13 ± 0.05 IUL/L in the 2nd controls. Referring to previously published data, a decline in sex-motivated behavior in Wistar rats is observed at the age of 18 months [4]. Observed natural signs signalling the ageing of reproductive systems in 15-to 18-month old female rats are the following: short estrous cycles disappear, long ovulatory cycles prevail (more than 7 days), regular cycles gradually transit to irregular cycles and the syndrome of constant estrus develops, that ultimately turns into anestrus.…”

“…To this point, the objective of modern physiology, gerontology and medicine is to extend the active period of life and maintain reproductive health. Reproductive system is one of the most important systems of entire body, and age-related decline in reproductive functions is one of the manifestations of biological ageing in humans and animals [3][4][5]. The activity of the reproductive system is directly related to age, and the level of sex hormones reflects and determines the biological age of a person.…”

Magnetic configuration scans during divertor operation of Wendelstein 7-X

“…Each machine module consists of two flip-symmetric (stellarator-symmetric) half-modules. One W7-X half-module comprises 5 types of independently powered NPCs and two types of independently powered PCs, which allows for the realization of a large diversity of magnetic configurations to maximize the machine's flexibility [7,8]. In the so-called Standard configuration, where all the NPCs carry equal currents and there is no current in the PCs, the rotational transform is equal to unity at the plasma boundary.…”
