- 睡眠と覚醒のサイクルのような 孤立したリズムではなく 生体時計の核となる 分子機構に 干渉しているかもしれません
研究 の 目的:
- 鬱病の理解,制御,そして 昼夜リズムとの複雑な関係について 最近の進歩を振り返るためです
- 鬱病率の上昇に寄与する要因を調査し,昼夜不整合に焦点を当てた.
- 鬱病の病原性,潜在的な病原性,および鬱病研究に関連する動物モデルに関する仮説を議論する.
主な方法:
- この研究は,うつ病と昼夜リズムに関する既存の文献のレビューです.
- 鬱病の増加率とその関連要因に関する証拠を評価しています.
- このレビューでは,うつ病に関連する仮説,潜在的な病因,および動物モデルについて論じています.
主要な成果:
- 昼夜リズムが乱れることは,MDDおよび関連疾患と一貫して関連しています.
- サーカディアンシステムの調節不良は,MDDの発症の感受性を高めるようです.

Circadian Rhythms and Gene Regulation
4.1K
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
124
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...

Management of Insomnia
320
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...

Depressive Disorders: Etiology
166
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.

Depression: Overview
332
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Biological Clocks and Seasonal Responses
38.1K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
