The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.9K
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...

Aging01:26

Aging

885
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...

Replicative Cell Senescence02:15

Replicative Cell Senescence

4.5K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

249
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Bone Disorders01:29

Bone Disorders

5.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

957
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Area of Science:

  • Gerontology
  • Neuroscience
  • Cell Biology

Background:

  • The hypothalamus is crucial for physiological changes during mammalian aging.
  • The precise mechanisms by which the hypothalamus influences aging are not fully understood.

Purpose of the Study:

  • To investigate the role of hypothalamic stem cells in mammalian aging.
  • To elucidate the mechanism by which hypothalamic stem cells may regulate aging.

Main Methods:

  • The study by Cai and colleagues (2017) focused on hypothalamic stem cells.
  • Analysis involved the examination of microRNA release in exosomes.

Main Results:

  • Evidence suggests that hypothalamic stem cells regulate aging.
  • MicroRNAs released in exosomes are implicated in this regulatory pathway.

Conclusions:

  • Hypothalamic stem cells, via exosomal microRNAs, represent a novel mechanism influencing mammalian aging.
  • This finding opens new avenues for understanding and potentially intervening in the aging process.
