[TEMPORAL ORDER DETERIORATION AND CIRCADIAN DISRUPTION WITH AGE]
Advances in Gerontology = Uspekhi Gerontologii
|February 10, 2016
Summary
Aging disrupts the body's internal clock, leading to a loss of temporal order and weakened circadian rhythms in mammals. This age-related circadian disruption affects molecular, tissue, and systemic levels, impacting overall health.
Area of Science:
- Chronobiology
- Gerontology
- Molecular Biology
Context:
- Aging is associated with progressive declines in physiological functions.
- Circadian rhythms, crucial for temporal organization, are known to deteriorate with age.
- Understanding these changes is vital for addressing age-related health issues.
Purpose:
- To review current knowledge on the age-related deterioration of temporal order.
- To explain the mechanisms and consequences of circadian disruption in aging.
- To highlight the impact on molecular, tissue, and systemic levels.
Summary:
- Aging leads to a gradual loss of temporal order and circadian rhythm disruption in mammals.
- Extra-circadian dissemination (ECD), a shift in rhythm frequencies and loss of stability, is a key consequence.
- This desynchronization involves heterochronic changes in cellular mechanisms and cumulative clockwork misalignment.
Impact:
- Provides insights into the fundamental biological processes of aging.
- Identifies potential targets for interventions to mitigate age-related health decline.
- Enhances understanding of how disrupted biological timing affects overall health and disease susceptibility.

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...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

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...

01:19The Effect of Aging on Tissues
4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
