Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

7.2K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

The Bone Matrix01:18

The Bone Matrix

8.9K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

Roles of Electrolytes: Calcium and Phosphate01:27

Roles of Electrolytes: Calcium and Phosphate

3.4K
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
The calcium concentration in blood plasma is primarily...

Bone Remodeling01:40

Bone Remodeling

41.1K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Bone Disorders01:29

Bone Disorders

7.8K
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...

Area of Science:

  • Materials Science
  • Inorganic Chemistry
  • Biomaterials Science

Background:

  • Metal-organic frameworks (MOFs) offer tunable properties for various applications.
  • Calcium-based MOFs are of interest for biomedical applications due to calcium's role in bone.

Purpose of the Study:

  • To synthesize and characterize new 3D calcium-bearing metal-organic frameworks.
  • To evaluate the bioactivity and bone-forming potential of the synthesized MOFs.

Main Methods:

  • Single crystal X-ray diffraction for structural characterization.
  • Incubation in simulated body fluid (SBF) to assess phase precipitation.
  • In vitro studies using MG63 osteoblast-like cells.

Main Results:

  • Two new frameworks, CaP1 ([Ca(H2O)3(HPXBP)]) and CaP2 ([Ca2(H2O)2(HPXBP)1.5]), were successfully synthesized and structurally elucidated.
  • CaP1 readily precipitated bone-precursor phases (OCP and hydroxyapatite) in SBF.
  • CaP1 demonstrated no toxicity to MG63 cells and stimulated bone mineralization.

Conclusions:

  • CaP1 exhibits promising bioactivity and bone regenerative potential.
  • CaP1 holds significant promise for the development of novel therapeutics for bone diseases like osteoporosis.
  • CaP2 showed limited bioactivity compared to CaP1.
