Effect of Scatterering on Coherent Anti-Stokes Raman Scattering (CARS) signals [PDF]
, 2017 We develop a computational framework to examine the factors responsible for scattering-induced distortions of coherent anti-Stokes Raman scattering (CARS) signals in turbid samples. We apply the Huygens-Fresnel Wave-based Electric Field Superposition (HF-

Exogenous lipids in myelination and myelination.
The Kaohsiung journal of medical sciences, 1997 Myelinogenesis is a scheduled process that depends on both the intrinsic properties of the cell and extracellular signals. In rat brain, myelin development is an essentially postnatal event and environmental interferences could affect myelin synthesis. Nutrition plays an important role, since severe postnatal malnutrition and essential fatty acid (EFA)

Towards in vivo g-ratio mapping using MRI: unifying myelin and diffusion imaging [PDF]
, 2020 The g-ratio, quantifying the comparative thickness of the myelin sheath encasing an axon, is a geometrical invariant that has high functional relevance because of its importance in determining neuronal conduction velocity.

Nanoscale correlated disorder in out-of-equilibrium myelin ultrastructure
, 2017 Ultrastructural fluctuations at nanoscale are fundamental to assess properties and functionalities of advanced out-of-equilibrium materials. We have taken myelin as a model of supramolecular assembly in out-of-equilibrium living matter.

Switching modes of myelination [PDF]
Nature Reviews Neuroscience, 2014 A new study shows that myelination may proceed in activity-dependent and -independent manners and that activity-dependent myelination is linked to neuregulin-induced signalling in oligodendrocytes, which makes these cells more sensitive to glutamate release.

Peroxisomal dysfunctions cause lysosomal storage and axonal Kv1 channel redistribution in peripheral neuropathy [PDF]
, 2017 Impairment of peripheral nerve function is frequent in neurometabolic diseases, but mechanistically not well understood. Here, we report a novel disease mechanism and the finding that glial lipid metabolism is critical for axon function, independent of ...

Lifelong cortical myelin plasticity and age-related degeneration in the live mammalian brain
Nature Neuroscience, 2018 Axonal myelin increases neural processing speed and efficiency. It is unknown whether patterns of myelin distribution are fixed or whether myelinating oligodendrocytes are continually generated in adulthood and maintain the capacity for structural ...

Journal of Neuroinflammation, 2011 Background Traumatic injury to axons produces breakdown of axons and myelin at the site of the lesion and then further distal to this where Wallerian degeneration develops.

Inflammation Combined with Ischemia Produces Myelin Injury and Plaque-Like Aggregates of Myelin, Amyloid-β and AβPP in Adult Rat Brain. [PDF]
, 2015 BackgroundIschemia, white matter injury, and Alzheimer's disease (AD) pathologies often co-exist in aging brain. How one condition predisposes to, interacts with, or perhaps causes the others remains unclear.ObjectivesTo better understand the link ...
