Bone Disorders01:29

Bone Disorders

6.6K
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...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.1K
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...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

7.0K
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...

Fractures: Bone Repair

6.4K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Chronic Kidney Disease II: Clinical Manifestations

909
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Proteoglycans01:05

Proteoglycans

5.1K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Area of Science:

  • Biomaterials Science
  • Orthopedics
  • Gerontology

Background:

  • Bone quality is compromised by non-enzymatic glycation (NEG), a process forming advanced glycation end-products (AGEs).
  • AGE accumulation accelerates with aging, diabetes, and certain osteoporosis treatments, elevating fracture risk.
  • Evaluating AGEs as biomarkers for fracture susceptibility is crucial due to increased incidence in aging and diabetic populations.

Purpose of the Study:

  • To summarize current methodologies for quantifying AGEs in bone tissue.
  • To discuss the relationship between AGE levels and bone fracture properties across different structural levels.

Main Methods:

  • Review of existing literature on AGE measurement techniques in bone.
  • Analysis of studies correlating AGEs with bone fracture characteristics.

Main Results:

  • Liquid chromatography and fluorometric assays are key methods for estimating bone AGEs.
  • AGEs impact fracture properties at the whole bone, apparent tissue, and matrix levels.

Conclusions:

  • Accurate measurement of AGEs is vital for assessing fracture risk.
  • Understanding the link between AGEs and bone mechanics can inform therapeutic strategies for osteoporosis and age-related bone fragility.
