Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

3.4K
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...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

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...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

3.0K
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:

Narcolepsy01:07

Narcolepsy

891
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Management of Insomnia01:19

Management of Insomnia

785
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
  • Urology
  • Chronobiology

Context:

  • Nocturia affects 60-90% of individuals over 60, significantly reducing quality of life.
  • Nighttime urination is regulated by brain arousal, kidney urine production, and bladder capacity.
  • The circadian clock system increasingly appears to modulate these regulatory factors.

Purpose:

  • To investigate the potential role of circadian clock system dysfunction in the etiology of nocturia.
  • To explore the association between nocturia risk factors and circadian clock system dysfunction.
  • To elucidate nocturia's causes by examining peripheral or central circadian clock dysfunction.

Summary:

  • Nocturia, characterized by nighttime urination, is prevalent in older adults and linked to diminished quality of life.
  • The regulation of nighttime urination involves brain arousal, kidney function, and bladder capacity, all potentially influenced by the circadian clock.
  • Common nocturia risk factors, including hypertension and diabetes, are associated with circadian clock system dysfunction, suggesting a potential etiological link.

Impact:

  • Highlights the critical role of the circadian clock system in regulating nocturia.
  • Provides a novel perspective on nocturia etiology, linking it to widespread circadian rhythm disruptions.
  • Suggests potential new avenues for nocturia prevention and treatment by targeting circadian clock mechanisms.
