Summary
Serbian research reveals aging impacts hormone signaling, immune response, and cholesterol metabolism. These age-related changes contribute to frailty, disease, and neurodegeneration, including Alzheimer's disease.
Area of Science:
- Gerontology and cellular damage research.
- Investigating the multi-faceted biological processes of aging.
Background:
- Aging is characterized by progressive cell and tissue damage accumulation.
- This damage leads to frailty, disability, and age-related diseases over decades.
Purpose of the Study:
- To investigate the influence of aging on hormone signaling, immune response, cholesterol metabolism, and neurodegenerative processes.
- To explore the underlying mechanisms of age-related physiological changes in Serbia.
Main Methods:
- Utilized murine models to study age-related changes in insulin signaling and glucose metabolism.
- Examined thymic tissue involution and early thymocyte differentiation in aging mice.
- Investigated the impact of dietary restriction on cholesterol metabolism.
- Explored the link between Alzheimer's disease pathology and age-altered Na-K-ATPase function.
Main Results:
- Age-related increase in insulinemia and deregulated glucose metabolism linked to insulin signaling changes.
- Age-sensitive alterations in early thymocyte differentiation observed alongside thymic involution.
- Dietary restriction's anti-aging effects attributed to modulation of cholesterol metabolism.
- Experimental evidence shows a connection between Alzheimer's neurodegeneration and altered Na-K-ATPase function in aging.
Conclusions:
- Serbian research provides new insights into how aging affects hormone signaling.
- The study highlights age-related impacts on immunological response and cholesterol metabolism.
- Findings suggest aging influences key physiological systems, potentially contributing to disease development.

01:26Aging
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
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...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
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...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
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...
01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
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 not...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
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...
