Multiple sclerosis (MS) is characterized by myelin sheath injury. A disintegrin and metalloprotease-17 (ADAM17), a disintegrin and metalloproteinase, is essential in regulating oligodendrocyte (OL) regeneration and remyelination under demyelinating conditions. iRhom1, a highly conserved inactive protease that belongs to the rhomboid family, is one of key regulators for ADAM17 maturation. However, it is unknown whether iRhom1 also plays a role in central neuron system myelination under demyelinating conditions like MS. In this study, we investigated the function of iRhom1/ADAM17 in cognitive capability in MS by establishing the mice with iRhom1 overexpression in the hippocampus.

Synthesis and evaluation of 6-arylaminobenzamides as positron emission tomography imaging ligands for the sphingosine-1-phosphate-5 receptor.

The sphingosine-1-phosphate-5 (S1P) receptor is one of the five membrane G protein-coupled receptors that are activated by the lysophospholipid, sphingosine-1-phosphate, resulting in regulation of many cellular processes. S1P receptors are located on oligodendrocytes and are proposed to influence oligodendrocyte physiology. Understanding S1P modulation during processes such as remyelination could have potential applications for demyelinating CNS disorders such as multiple sclerosis (MS).

Marburg disease (malignant multiple sclerosis, MS) is a rare, acute MS variant, predominantly occurring among young adults. Because it is characterized by rarity, high morbidity and mortality rates, the disease needs to be further characterized, and the experience of the physicians play a role in treatment regimens. We report the case of a 15-years-old female presenting with progressive weakness over the limbs, hyperreflexia and loss of sensation by physical examination, lab tests and radiological investigations (MRI).

Study Objectives: To elucidate whether awake handedness in sexsomnia is retained during sleep to uncover potential clues about the underlying neurophysiologic mechanisms.
Methods: Participants' and observers' self-reported handedness during sexsomnia events.
Results: Case 1: A 22 y/o right-handed female with an eight-year history of nocturnal sleep-related masturbatory behavior (SMB) involving the left hand (LH) exclusively.
A Novel Case of Pulmonary Sclerosing Diffuse PEComatosis With Neuroendocrine Cell Hyperplasia.

Proliferations of neoplastic perivascular epithelioid cells (PECs) may occur within the lung and extrathoracic sites. The term "PEComatosis" is applied to multiple or diffuse microscopic proliferations of neoplastic PECs. Pulmonary diffuse PEComatosis is extremely rare, with only one case documented in the literature to date.

Background And Purpose: MRI is crucial for multiple sclerosis (MS), but the relative value of portable ultra-low field MRI (pULF-MRI), a technology that holds promise for extending access to MRI, is unknown. We assessed white matter lesion (WML) detection on pULF-MRI compared to high-field MRI (HF-MRI), focusing on blinded assessments, assessor self-training, and multiplanar acquisitions.
Methods: Fifty-five adults with MS underwent pULF-MRI following their HF-MRI.
