Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To propose a signal acquisition and modeling framework for multi‐component tissue quantification that encompasses transmit field inhomogeneity, multi‐component relaxation and magnetization transfer (MT) effects. Theory and Methods By applying off‐resonance irradiation between excitation and acquisition within an RF‐spoiled gradient ...

The Multiple Roles of Myelin Protein Genes During the Development of the Oligodendrocyte
ASN Neuro, 2009 It has become clear that the products of several of the earliest identified myelin protein genes perform functions that extend beyond the myelin sheath. Interestingly, these myelin proteins, which comprise proteolipid protein, 2′, 3′-cyclic nucleotide 3′-

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Dorsal rhizotomy, or spinal dorsal nerve root lesioning, is a surgical procedure used to treat intractable nerve pain by selectively severing sensory afferent nerve roots. This study aimed to evaluate whether multiparametric MRI, including diffusion tensor imaging (DTI), quantitative magnetization transfer (qMT), chemical exchange ...

Dysregulation of NAD+ metabolism induces a Schwann cell dedifferentiation program [PDF]
, 2018 The Schwann cell (SC) is the major component of the peripheral nervous system (PNS) that provides metabolic and functional support for peripheral axons. The emerging roles of SC mitochondrial function for PNS development and axonal stability indicate the

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To investigate how the relaxation rates (R1, R2) and asymmetry indices (AI), derived from phase‐cycled balanced steady‐state free precession (pc‐bSSFP) data, depend on the orientation of white matter (WM) fiber tracts at different field strengths.

Integrative Zoology, EarlyView.The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
