Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.7K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Disorders

5.0K
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...

Changes in the Appendicular Skeleton with Age

3.3K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

The Proteasome02:18

The Proteasome

9.9K
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

The Functions of the Skeletal System01:22

The Functions of the Skeletal System

5.6K
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

3.4K
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...

Area of Science:

  • Gerontology
  • Bone and Muscle Physiology
  • Geriatric Medicine

Background:

  • Osteosarcopenia is defined as the coexistence of sarcopenia (low muscle mass and function) and osteopenia/osteoporosis (low bone mineral density).
  • Its prevalence in community-dwelling adults over 65 varies widely (5-37%) due to differing definitions and study populations.
  • The clinical significance and independent risk associated with osteosarcopenia compared to its individual components remain subjects of ongoing research and debate.

Purpose of the Study:

  • To review the latest research and controversies surrounding osteosarcopenia.
  • To examine the association of osteosarcopenia with negative health outcomes in older adults.
  • To discuss potential interventions and chart a path forward for osteosarcopenia research.

Main Methods:

  • Systematic review of current literature on osteosarcopenia.
  • Analysis of studies investigating prevalence, risk factors, and outcomes.
  • Evaluation of emerging research on interventions like exercise, nutrition, and pharmacotherapy.

Main Results:

  • Mixed findings exist regarding the association of osteosarcopenia with adverse outcomes, largely due to inconsistent definitions and measurement methods.
  • Prevalence estimates vary significantly across different populations and settings.
  • Research into interventions is nascent, with exercise, protein supplementation, and pharmacotherapy being explored.

Conclusions:

  • A lack of consensus on the operational definition of sarcopenia and accurate muscle mass measurement hinders progress.
  • Standardizing definitions and measurement tools is crucial for advancing osteosarcopenia research.
  • Further investigation is needed to clarify the unique risks of osteosarcopenia and develop effective interventions.
