Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption01:22

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

145
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

129
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...

Defenses Against Pathogens and Herbivores

29.3K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation02:17

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

3.8K
Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Area of Science:

  • Plant biochemistry and molecular biology
  • Gerontology and aging research
  • Natural product chemistry

Background:

  • Terpenoids are abundant plant secondary metabolites, but their geroprotective potential is largely unexplored.
  • Unlike polyphenols, terpenoids are not commonly linked to anti-aging properties.
  • Existing research has not systematically evaluated terpenoids against established geroprotector criteria.

Purpose of the Study:

  • To assess terpenoids for their conformity with primary and secondary criteria of geroprotectors.
  • To identify specific classes of terpenoids that exhibit promising geroprotective effects.
  • To highlight terpenoids as an underappreciated source for developing interventions against aging and age-related diseases.

Main Methods:

  • Evaluation of terpenoid biological effects against defined geroprotector criteria.
  • Assessment of primary criteria: lifespan extension, aging biomarker improvement, low toxicity, minimal adverse effects, and quality of life enhancement.
  • Assessment of secondary criteria: conserved mechanisms, reproducibility, prevention of age-associated diseases, and increased stress resistance.

Main Results:

  • Several terpenoid classes demonstrated strong compliance with both primary and secondary geroprotector criteria.
  • Specific terpenoids were identified as meeting multiple criteria for lifespan extension and healthspan improvement.
  • The study confirmed the broad applicability of terpenoids across different aging models.

Conclusions:

  • Terpenoids represent a significant and underestimated reservoir of potential geroprotective compounds.
  • These natural products can effectively modulate aging mechanisms and combat age-related pathologies.
  • Further research into terpenoids could lead to novel anti-aging therapies and improved healthspan interventions.
