The Effect of Aging on Tissues01:19

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...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

4.9K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

359
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...

Proteins: Dietary Sources and Requirements01:28

Proteins: Dietary Sources and Requirements

2.5K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Bone Disorders01:29

Bone Disorders

8.8K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

828
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...

Area of Science:

  • Gerontology
  • Nutritional Science
  • Exercise Physiology

Background:

  • Aging is associated with sarcopenia, a decline in muscle mass and strength.
  • Optimal protein intake is crucial for maintaining muscle health in older adults.

Purpose of the Study:

  • To review current evidence on protein intake and supplementation in older adults.
  • To examine effects on muscle protein synthesis, strength, and performance.

Main Methods:

  • Systematic review of recent studies on protein supplementation.
  • Analysis of effects on muscle protein synthesis, strength, and functional outcomes.

Main Results:

  • Higher protein intake (above 0.8 g/kg/day) shows benefits for older adults.
  • Fast-acting proteins like whey enhance muscle protein synthesis.
  • Milk protein supplementation increased strength in frail individuals; combined with exercise, it increased muscle mass.

Conclusions:

  • Protein supplementation positively impacts muscle protein synthesis, mass, and strength in older adults.
  • Larger, longer-duration studies are needed to confirm clinical relevance.
