Aging

1.1K
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...

The Effect of Aging on Tissues

4.2K
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...

Mitochondria01:37

Mitochondria

21.5K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Cognitive Development During Adulthood

1.3K
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,...

Bone Disorders01:29

Bone Disorders

8.7K
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...

Development of Human Microbiota01:30

Development of Human Microbiota

44
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

Area of Science:

  • Geriatric Medicine
  • Psychology of Aging
  • Oncology

Background:

  • Aging involves psychological changes that interact with cancer diagnosis and treatment.
  • Older adults may experience increased stress due to comorbidities and life losses.
  • Conversely, aging can foster character strengths beneficial for coping with cancer.

Purpose of the Study:

  • To highlight the necessity of integrating psychological aspects of aging into geriatric cancer care.
  • To explore the dual nature of psychological impact in older cancer patients.

Main Methods:

  • This is a conceptual review and synthesis of existing knowledge.
  • No specific patient data or experimental methods were employed.

Main Results:

  • Psychological factors significantly influence the experience of cancer in older adults.
  • Negative impacts include stress from comorbid conditions and losses.
  • Positive impacts stem from developed resilience and character strengths.

Conclusions:

  • Geriatric medicine must acknowledge and address the psychological dimensions of aging in cancer patients.
  • A holistic approach considering both challenges and strengths is essential for optimal care.
