Dependence of the Extra‐Cellular Diffusion Coefficient on the Fractions of Neurites and Cell Bodies in Gray Matter

Magnetic Resonance in Medicine, EarlyView.
Purpose The dependence of the long‐time (tortuosity) limit of the extra‐cellular diffusivity on the intra‐cellular volume fraction is of fundamental importance for microstructure modeling. While such dependencies have been explored for the white matter, the tortuosity limit in gray matter is unknown due to complex cell composition and geometry. Here we

Ultrasound‐Confirmed Median Nerve Pseudoconduction Block due to Anatomical Variation

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Conduction block (CB) at non‐entrapment sites is an important electrodiagnostic (EDX) feature supporting acquired demyelinating neuropathies. However, anatomical variation may produce pseudoconduction block, mimicking true CB.

Administration of Schwann Cell‐Like Cells Differentiated From Tonsil‐Derived Mesenchymal Stem Cells Promotes Peripheral Nerve Regeneration by Inducing Macrophage Polarization in a Chronic Constriction Injury Model

Muscle &Nerve, EarlyView.
TMSC‐SCs were mixed with fibrin adhesive and administered into the sciatic nerve of CCI rats, and nerve conduction studies and histopathological observations confirmed the regeneration of the peripheral nerve and gastrocnemius muscle. In addition, the expression of M1 and M2 macrophage markers was observed after the administration of TMSC‐SCs. ABSTRACT

Imaging patterns and genetic associations of brain atrophy across distinct symptom stages in Parkinson's disease

Neuroprotection, EarlyView.
Early disease stages showed limited cortical atrophy and enrichment of synaptic and calcium signaling pathways, whereas advanced stages demonstrated widespread cortical degeneration associated with immune activation and extracellular matrix remodeling.

Fetal Brain Abnormalities Following Laser Surgery for Twin‐to‐Twin Transfusion Syndrome: Imaging Patterns and Evolution

Prenatal Diagnosis, EarlyView.
ABSTRACT Introduction Severe brain injury has been reported following fetoscopic laser ablation (FLA) for twin‐to‐twin transfusion syndrome (TTTS), but imaging patterns and temporal evolution remain poorly defined. This study aimed to characterize the progression of severe brain injury after FLA. Methods We conducted a retrospective case series of TTTS

Evaluating the efficacy of obturator cryoneurolysis for hip adductor spasticity: An observational, prospective study

PM&R, EarlyView.
Abstract Background Hip adductor spasticity is a common affliction among patients with disorders of the central nervous system. Cryoneurolysis is a novel intervention for spasticity involving the application of extreme cold to a nerve. This induces axonal breakdown, relieving spasticity.

Feedback-Driven Assembly of the Axon Initial Segment [PDF]

Neuron, 2019
The axon initial segment (AIS) is a unique neuronal compartment that plays a crucial role in the generation of action potential and neuronal polarity. The assembly of the AIS requires membrane, scaffolding, and cytoskeletal proteins, including Ankyrin-G ...
