This ultimately causes the myelin sheath
to detach from the axon and leads to malfunctioning neural signals.
thickening in D-gal-treated fibers may result from intra-myelin degeneration such as loosening or splitting of the myelin lamellae which ultimately alters the ratio of the sheath thickness to the fiber diameter.
Within that group, researchers found only 25 patients had received any vaccine in the six weeks before the onset of Guillain-Barre, an acute disease that results in destruction of a nerve's myelin sheath
and peripheral nerves.
There are medications that can help reduce the impact of the disease, such as glatiramer, which helps prevent the body's immune system from attacking the myelin sheath
around nerve fibers.
Damage to the myelin sheath
impairs the conduction of signals in the affected nerves and leads to locomotor problems.
9:15 EFFECTS OF LIGHT EXPOSURE AND VITAMIN D ON THE DEVELOPMENT OF MYELIN BASIC PROTEIN IN THE MYELIN SHEATH
OF NEURONAL AXONS IN JUVENILE ZEBRAFISH **, Callie Holloway * and Linda G.
These areas reveal inflammation of the nerve fibers' myelin sheath
, which provides insulation and facilitates the transmission of electric signals.
The last part of the book presents applications in areas such as imaging myelin sheath
by CARS microscopy, imaging lipid metabolism, CARS microscopy studies of liquid crystals, and coherent Raman scattering imaging of drug delivery systems.
Research Fellow Dr Samuel Wharton said: "While most MRI-based research focuses on tissue measurements at the millimeter length scale, our experimental scans on healthy human volunteers and modeling of the myelin sheath
shows that much more detailed microscopic information relating to the size and direction of nerve fibers can be generated using fairly simple imaging techniques.
White matter is so named because of a whitish fatty substance called the myelin sheath
that coats the axons and facilitates the transmission of electrical impulses within the nervous system.
The myelin sheath
that surrounds nerve fibers in the brain and spinal cord is damaged by repeated immune attacks in MS.
According to the researchers, studies indicate that defects in myelin sheath
regeneration can be at least partly corrected by surgically introducing cells found in the blood of younger mice into the spinal cords of older mice.
A whitish material that surrounds and insulates the fibers of nerve cells.
For anyone unfamiliar with MS, it is a debilitating neurodegenerative disease apparently caused by the deterioration of the myelin sheath
that surrounds many of the important nerves in the body, especially in the brain.
MS, a chronic disease of the nervous system, affects the brain and spinal cord by damaging the myelin sheath
, which surrounds and protects nerve cells.
