Circulating sex steroid hormones are critical for neural function and development of neuroplasticity in many regions of the central nervous system. In the spinal cord, our knowledge of steroid hormone influence mostly derives from mechanistic studies of pain processing in dorsal spinal cord circuits; less is known regarding hormonal influence of ventral spinal motor function. Gonadectomy (surgical removal of the testes in males and ovaries in females) rapidly and persistently reduces circulating sex steroids in both females and males, providing a means to interrogate the role of hormones on neural function. Here we provide a next-generation RNA sequencing (RNA-seq) data set to evaluate the impact of gonadectomy on the transcriptome of ventral spinal cord tissue of adult female and male rats.

Background And Objectives: Myelitis is a relatively common clinical entity for neurologists, with diverse underlying causes. The aim of this study was to describe the incidence of myelitis, its causes, clinical presentation, and factors predicting functional outcomes and relapses.
Methods: Using the Swedish National Patient Registry, we identified all adult patients in Stockholm County between 2008 and 2018 using International Classification of Diseases, 10th Edition (ICD-10) codes likely to include myelitis.

Study Design: A retrospective study with a crossover design.
Objectives: Maintaining mean arterial pressure (MAP) is crucial in the early management of SCI, yet the role of oral midodrine in this setting remains unclear. This study evaluates whether midodrine facilitates IV vasopressor weaning within 24 hours of initiation.

A considerable number of individuals are diagnosed with idiopathic trigeminal neuralgia. In order to achieve a more complete understanding of the pathophysiology, it is essential to adopt a range of novel approaches and utilize new animal models. This study investigated changes in the messenger RNA (mRNA) expression of ion-channels in a newly developed animal model of trigeminal neuropathic pain induced by cervical spinal dorsal horn compression.

Mutations in Delta Like Non-Canonical Notch Ligand 1 (DLK1), a paternally expressed imprinted gene, underlie central precocious puberty (CPP), yet the mechanism remains unclear. To test the hypothesis that DLK1 plays a role in gonadotropin releasing hormone (GnRH) neuron ontogeny, 75 base pairs were deleted in both alleles of DLK1 exon 3 with CRISPR-Cas9 in human pluripotent stem cells (hPSCs). This line, exhibiting More than 80% loss of DLK1 protein, was differentiated into GnRH neurons by dual SMAD inhibition (dSMADi), FGF8 treatment and Notch inhibition, as previously described, however, it did not exhibit accelerated GNRH1 expression.
