A Major Regulator of the Circadian Rhythm of Core Temperature in Humans by Cagnaccit, Elliotti, and Yen - Article Example

The paper "A Major Regulator of the Circadian Rhythm of Core Temperature in Humans by Cagnaccit, Elliotti, and Yen" is a delightful example of an article on medical science. This article basically entails an exploration of the core body temperature’s circadian rhythms. The basic exploration was to provide evidence of the regulation of core body temperature’s circadian rhythms to that of the normal cycle of sleep and wake. The researchers hypothesized that night-time melatonin secretion may be concerned with the regularization of the human BTC circadian rhythm. Since Pineal melatonin discharge takes place contemporaneously during the nocturnal hours and is interceded by the commencement of beta-adrenoceptors cells during the night. The research was conducted by performing experiments with a sample of 12 women, usually boarded to light and dark cycle for two days. It was concluded that the core body temperature’s circadian rhythms were inversely linked to that of melatonin. The established hypothermic attributes of melatonin are responsible for the propagation of at least forty percent of the circadian BTC rhythm’s amplitude. The exploitation of melatonin levels may thus provide an opportunity for clinical resynchronization of the BTC rhythm under circumstances when BTC rhythms are desynchronized either due to jet-lag or night-shift work (Cagnaccit, Elliotti and Yen 447). 

The title was sufficiently descriptive as the article entailed a causal study between the quoted variables. The study was intended to explore the relationship between the melatonin secretion and the circadian rhythms of the core body temperature. The subject was important as due to the rapid industrialization, humans are obliged to work in the night shifts to attain a maximum number of outputs. While the night-time work may lead to the creation of dissociation within the human circadian rhythms and it may also alter or change the phase relationship existing between the endogenous rhythms and environmental time. So the study provides a relationship between the melatonin levels and the core body temperature’s circadian rhythms that can be utilized in bringing harmony in cases of desynchronized BTC rhythms either due to night shift jobs or jet-lag.
Questions
1. Whether the sleep and melatonin secretion collectively related to the excessive hypothermic effect?
2. Whether sleep deprivation leads to a reduction in the amplitude of circadian rhythms of the BTC? Read More
