Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.6K
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

371
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...

Long-term Depression01:05

Long-term Depression

33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Freezing Point Depression and Boiling Point Elevation

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressants01:28

Depressants

462
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Pulse rhythm01:30

Pulse rhythm

1.4K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Chronobiology

    Background:

    • Depressive disorders are linked to neurobiological alterations, including hyperactivity of the hypothalamic-pituitary-adrenal axis, impaired neuroplasticity, and disturbed circadian rhythms.
    • Stressors interact with genetic predispositions to potentially destabilize the body's internal clock, contributing to depressive symptoms.

    Purpose of the Study:

    • To explore the relationship between depressive disorders and circadian rhythm disturbances.
    • To review chronobiological therapies for treating circadian symptoms in depression.

    Main Methods:

    • Review of existing scientific literature on depression, circadian rhythms, and chronotherapeutics.
    • Analysis of the effectiveness and evidence base for treatments like light therapy and sleep deprivation.

    Main Results:

    • The exact causal links between depression and circadian rhythm disruption require further clarification.
    • Various chronotherapeutics exist for circadian symptoms, with differing levels of effectiveness and scientific support.
    • Successful depression treatment often correlates with improvements in circadian rhythm regulation.

    Conclusions:

    • Chronobiological therapy offers a targeted approach for managing circadian disturbances associated with depression.
    • Further research is needed to fully elucidate the complex interplay between depression and circadian system function.
