|June 10, 2015
Summary
Ageing increases disease susceptibility and frailty, potentially creating a feedback loop. Understanding the genetic and intervention mechanisms influencing ageing and lifespan is crucial for dissecting these complex processes.
Area of Science:
- Gerontology and genetics.
- Molecular biology and evolutionary medicine.
Background:
- Ageing is characterized by increased susceptibility to disease and frailty.
- A positive feedback loop may exist where disease exacerbates ageing phenotypes.
- Lifespan is modifiable through genetic factors and interventions, but mechanisms remain unclear.
Purpose of the Study:
- To investigate the complex interplay between ageing, disease, and lifespan.
- To elucidate the mechanisms underlying lifespan modification.
- To understand the influence of natural selection on ageing and disease processes.
Main Methods:
- Analysis of genetic pathways influencing ageing.
- Examination of allelic variants associated with ageing and disease.
- Investigating interventions that modify lifespan.
Main Results:
- The relationship between disease and ageing phenotypes suggests a feedback loop.
- Genetic factors and interventions can modify lifespan.
- Mechanisms of ageing and lifespan modification are not fully understood.
Conclusions:
- Dissecting individual changes in ageing is challenging due to its link with disease and lifespan.
- Further research into specific pathways and genetic variants will illuminate the influence of natural selection on ageing.
- Understanding ageing requires a multi-faceted approach considering genetics, disease, and evolutionary factors.

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...

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...

01:15Drug Dosing: Geriatric Patients
359
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
331
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...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
816
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
350
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
