Summary
Occupational exposure to n-hexane elevates serum myelin basic protein (MBP) levels in workers. Elevated MBP can serve as an effective biomarker for detecting n-hexane exposure.
Area of Science:
- Neuroscience
- Toxicology
- Biochemistry
Context:
- Occupational exposure to n-hexane is prevalent in industries like printing and shoe manufacturing.
- Chronic exposure to n-hexane can lead to neurotoxicity, affecting the peripheral nervous system.
- Biomarkers are crucial for monitoring exposure and assessing health risks in occupational settings.
Purpose:
- To investigate the relationship between occupational n-hexane exposure and serum myelin basic protein (MBP) levels.
- To determine if MBP can be utilized as a reliable biomarker for n-hexane exposure.
- To assess the impact of varying n-hexane exposure levels on MBP expression.
Summary:
- This study analyzed 269 n-hexane-exposed workers and 104 controls, measuring urinary 2,5-hexanedione and serum MBP levels.
- Serum MBP levels were significantly higher in n-hexane-exposed groups (high and low exposure subgroups) compared to controls.
- A positive correlation was observed between urinary 2,5-hexanedione and serum MBP levels, indicating dose-dependency.
Impact:
- Serum MBP levels are significantly elevated in workers occupationally exposed to n-hexane.
- Serum MBP can serve as an effective and sensitive biomarker for monitoring n-hexane exposure.
- Findings contribute to understanding n-hexane neurotoxicity and inform occupational health surveillance strategies.

01:15¹H NMR of Conformationally Flexible Molecules: Variable-Temperature NMR
The axial and equatorial protons in cyclohexane can be distinguished by performing a variable-temperature NMR experiment. In this process, except for one proton, the remaining eleven protons are replaced by deuterium. The deuterium substitution avoids the possible peak splitting caused by the spin-spin coupling between the adjacent protons. The remaining proton flips between the axial and equatorial positions.
01:27π Electron Effects on Chemical Shift: Overview
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0, resulting in...
01:14π Electron Effects on Chemical Shift: Aromatic and Antiaromatic Compounds
In aromatic compounds, such as benzene, the circulation of (4n + 2) π-electrons sets up a diamagnetic or diatropic ring current around the perimeter of the molecule. This current induces a magnetic field that opposes the external field inside the ring and reinforces it on the outside. The protons in benzene are deshielded and exhibit high chemical shifts in the range 6.5–8.5 ppm. The shielding effect at the center of the ring is evident in complex aromatic molecules, such as annulenes. In...
