Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.7K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Insufficient Sleep and Sleep Deprivation

1.3K
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

3.3K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

480
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Area of Science:

  • Sleep science
  • Metabolic health
  • Obesity research

Background:

  • Night shift work is prevalent and may affect sleep quality.
  • Sleep quality influences various physiological processes.
  • Understanding factors contributing to obesity is crucial for public health.

Purpose of the Study:

  • To examine the relationship between night shift work and sleep quality.
  • To investigate correlations between sleep quality and obesity-related biomarkers.
  • To analyze factors impacting obesity.

Main Methods:

  • Utilized data from the National Survey of Midlife Development in the United States II (MIDUS II) and its Biomarker Project.
  • Analyzed data from 883 subjects, linking night shift work, sleep quality, and biomarker data.
  • Employed logistic regression to identify factors associated with obesity.

Main Results:

  • Night shift workers reported lower sleep quality.
  • Poor sleep quality correlated with unfavorable levels of HbA1c, total cholesterol, triglycerides, and DHEA.
  • Sleep quality was associated with inflammatory and antioxidant markers, and significantly with obesity (OR: 1.10).

Conclusions:

  • Poor sleep quality from night shift work disrupts circadian rhythms.
  • This disruption leads to adverse changes in metabolic, inflammatory, and antioxidant biomarkers.
  • These biomarker alterations may contribute to an increased incidence of obesity.
