Summary
This study analyzed trace elements in human intervertebral discs (IVDs), finding unique elemental profiles and correlations with age and environment. Understanding these trace element patterns is key for IVD health.
Area of Science:
- Biochemistry
- Environmental Health
- Orthopedics
Background:
- Limited research exists on trace elements (TE) in human intervertebral disc (IVD) tissue.
- TEs in IVDs can indicate metabolic processes or environmental pollution.
- The IVD's unique physiology impacts its communication and nutrient exchange.
Purpose of the Study:
- To investigate the presence and concentrations of various trace elements in human IVD tissue.
- To explore correlations between trace elements, patient age, and environmental factors.
- To compare TE levels in IVDs with those in other human tissues.
Main Methods:
- Analysis of 30 human IVDs from patients undergoing surgery for degenerative disc disease.
- Quantification of Aluminum (Al), Cadmium (Cd), Lead (Pb), Copper (Cu), Nickel (Ni), Molybdenum (Mo), Magnesium (Mg), and Zinc (Zn) using atomic absorption spectrometry.
Main Results:
- Al, Pb, Cu, Mg, and Zn were detected in all samples.
- Pb showed a positive correlation with age; Ni correlated with population density.
- Copper concentrations were higher in IVDs than in other tissues, with significant inter-element correlations observed.
Conclusions:
- This study provides one of the few elemental profiles of human intervertebral discs in degenerative disease.
- Significant differences in TE concentrations were found between IVDs and other tissues.
- Understanding TE accumulation patterns is crucial for comprehending IVD nutrition and metabolism.

01:27Degenerative Disc Disease I: Introduction
4
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

01:23Degenerative Disc Disease ll: Pathophysiology
4
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

01:29Herniated Intervertebral Disc l: Introduction
13
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

1.6K
Inductively coupled plasma–mass spectrometry (ICP–MS) is a highly selective and sensitive technique for accurate elemental analysis. Though the analysis of ICP–MS mass spectra is comparatively straightforward, it is affected by spectroscopic and non-spectroscopic interferences. Spectroscopic interferences arise when the plasma contains ionic species with an m/z value the same as the analyte ion. Spectroscopic interference can be categorized as isobaric, polyatomic ions, and...

AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...

For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
