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...

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:

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

453
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...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

2.5K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Management of Insomnia

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...

Area of Science:

  • Sleep Medicine
  • Chronobiology
  • Circadian Rhythm Disorders

Background:

  • Jet lag and shift work disorder are common circadian rhythm sleep-wake disorders.
  • These disorders arise from a mismatch between the internal biological clock and external environmental cues.
  • While not all travelers or shift workers develop a disorder, prevalence estimates suggest significant impact, with 5%-10% of shift workers experiencing shift work disorder.

Purpose of the Study:

  • To summarize the nature of circadian rhythm sleep-wake disorders.
  • To outline current treatment strategies for jet lag and shift work disorder.
  • To highlight the goals of therapeutic interventions in managing these conditions.

Main Methods:

  • Review of existing literature on circadian rhythm sleep-wake disorders.
  • Analysis of behavioral and pharmacological treatment approaches.
  • Examination of the role of light-dark cycles, sleep schedules, and melatonin.

Main Results:

  • Jet lag disorder prevalence is not clearly defined, but affects individuals experiencing trans-meridian travel.
  • Shift work disorder affects approximately 5%-10% of individuals engaged in shift work.
  • Treatment strategies aim to resynchronize the internal circadian clock with the external environment.

Conclusions:

  • Behavioral therapies, including sleep hygiene and light-dark cycle management, are key to treatment.
  • Pharmacological agents can address insomnia and excessive sleepiness.
  • Melatonin plays a role in facilitating sleep and promoting circadian realignment.
