Witryna8 maj 2024 · The myelination of axons in peripheral nerves requires precisely coordinated proliferation and differentiation of Schwann cells (SCs). We found that the activity of the mechanistic target of rapamycin complex 1 (mTORC1), a key signaling hub for the regulation of cellular growth and proliferation, is progressively extinguished as … Witryna1 mar 1995 · Magnetic resonance imaging (MRI) is the best method for assessing myelination in infants and young children. Although delayed myelination is a common neuroradiologic diagnosis, there are few or no data regarding the reliability of this diagnosis or radiographic and clinical findings in cohorts of such patients.
WitrynaThe normal process of myelination of the brain mainly occurs during the first year of life. This process as known from histology can be visualized by MRI. Because of the very long T1 and T2 of immature brain tissue it is necessary to use adjusted pulse sequences with a long TR in order to obtain sufficient tissue contrast. With long TR SE images five … Witryna15 wrz 2024 · The bimodal waveform of sensory nerves disappeared with growth. Our findings suggest that the underlying cause of the bimodal waveform is an immature myelin sheath and that peripheral nerve myelin development may continue until the age of 15–16 years; this duration is longer than that previously reported by other studies.
