Cancer Prevention02:59

Cancer Prevention

6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Bone Disorders01:29

Bone Disorders

3.9K
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...

Preventive Healthcare Services01:30

Preventive Healthcare Services

1.1K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

2.4K
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...

Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

3.6K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Area of Science:

  • Gerontology
  • Muscle Physiology
  • Public Health

Background:

  • Sarcopenia is a significant risk factor for adverse health outcomes in older adults.
  • The lack of a universally accepted definition poses challenges for diagnosis and research.
  • Accurate identification of sarcopenia is crucial for timely intervention.

Purpose of the Study:

  • To review current diagnostic criteria and screening tools for sarcopenia.
  • To evaluate the efficacy of various interventions for managing sarcopenia.
  • To highlight the importance of physical activity in combating sarcopenia.

Main Methods:

  • Analysis of recent diagnostic criteria and assessment tools for muscle mass, strength, and physical performance.
  • Review of evidence for interventions including resistance training, endurance training, and nutritional strategies.
  • Examination of screening tools for identifying at-risk populations.

Main Results:

  • Multiple sarcopenia algorithms exist, each with strengths and weaknesses.
  • Various exercise modalities (resistance, endurance, power training, etc.) show benefits.
  • Nutritional interventions and emerging drug therapies offer potential treatment avenues.

Conclusions:

  • Standardized diagnostic criteria are needed for sarcopenia.
  • A combination of exercise, nutrition, and potentially pharmacotherapy is key to managing sarcopenia.
  • Physical activity remains a cornerstone in preventing and treating sarcopenia.
