The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

2.3K
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...

Aging

165
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...

Clinical Trials01:16

Clinical Trials

7.1K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Clinical Trials: Overview

3.3K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Mitochondria01:37

Mitochondria

14.5K
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,...

Alzheimer's Disease: Treatment01:22

Alzheimer's Disease: Treatment

259
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Area of Science:

  • Gerontology and aging research
  • Cellular and molecular biology of aging
  • Biomarker development for age-related diseases

Background:

  • Aging is associated with increased morbidity and mortality, driven by factors like chronic inflammation, DNA damage, mitochondrial dysfunction, and cellular senescence.
  • Specific molecular pathways and cellular processes are implicated in age-related phenotypes such as frailty, reduced resilience, and multi-morbidity.

Purpose of the Study:

  • To review current biomarkers for aging and morbidity.
  • To assess the outcomes of anti-aging intervention studies in humans.
  • To discuss the future of clinical trials targeting the aging process.

Main Methods:

  • Review of existing literature on aging mechanisms, biomarkers, and human intervention studies.
  • Analysis of pathways targeted by interventions like caloric restriction and drugs affecting mechanistic target of rapamycin (mTOR), sirtuins, and senescent cells.
  • Evaluation of the feasibility and ethical considerations of human lifespan studies.

Main Results:

  • Animal models show significant health and lifespan extension with interventions targeting aging pathways.
  • Translation of these findings to humans remains uncertain.
  • Development of reliable age- and morbidity-associated biomarkers is crucial for human studies.

Conclusions:

  • Current biomarkers and human intervention study results are presented.
  • Future human clinical trials for aging interventions may involve larger Phase 2 and 3 studies if safety and tolerability are confirmed.
