It has been reported that the nervous system can regulate immune reactions through various mechanisms. However, the role of splenic sympathetic nerve activity in the autoimmune reactions during the pathogenesis of experimental autoimmune encephalomyelitis (EAE) remained unclear. Here, we blocked the activity of the splenic sympathetic nerve and found that the number of adaptive immune cells, such as CD4 T cells, CD8 T cells and B cells, were upregulated.

Objectives: Exercise as a non-pharmacological intervention can exert beneficial effects directly through exosomes crossing the blood-brain barrier and reduce apoptosis after cerebral ischaemia/reperfusion injury (CI/RI). miRNA-124 (miR-124) is present in exosomes and plays an important role in regulating cerebral neurological activity; however, the mechanism of the relationship between exercise and the activity of exosomes and apoptosis after CI/RI remains unclear. Therefore, the present study investigated the effects of exercise preconditioning on cerebral ischemia/reperfusion injury from the perspective of exosomal miR-124 and apoptosis.

Objective: This study aimed to investigate the extent of gender disparities in financial interactions between neurosurgeons and the medical device industry, examining the differences in the number, amount, and types of payments made to male and female neurosurgeons.
Methods: Utilizing data from the Centers for Medicare & Medicaid Services Open Payments database covering 2016-2022, the authors conducted a comprehensive analysis of industry payments to neurosurgeons. This methodology included univariate and multivariate analyses to examine the disparities in payments, with a focus on identifying significant differences in compensation across genders.
The Coexistence of Carotico-Clinoid Foramen and Interclinoidal Osseous Bridge: An Anatomo-Radiological Study With Surgical Implications.
Oper Neurosurg (Hagerstown)
February 2025
Rhoton Neurosurgery and Otolaryngology Surgical Anatomy Program, Mayo Clinic, Rochester , Minnesota , USA.
Background And Objectives: The coexistence of complete carotico-clinoid bridge (CCB), an ossification between the anterior (ACP) and the middle clinoid (MCP), and an interclinoidal osseous bridge (ICB), between the ACP and the posterior clinoid (PCP), represents an uncommonly reported anatomic variant. If not adequately recognized, osseous bridges may complicate open or endoscopic surgery, along with the pneumatization of the ACP, especially when performing anterior or middle clinoidectomies.
Methods: According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews guidelines, a systematic scoping review was conducted up to June 5, 2023.
Taking the Next Step in Neurologic Rehabilitation: Contributions of Intensity and Variability of Stepping Tasks during Locomotor Training.
Phys Ther

Department of Physical Medicine and Rehabilitation.
Research over the past 20 years indicates the amount of task-specific walking practice provided to individuals with stroke, brain injury, or incomplete spinal cord injury can strongly influence walking recovery. However, more recent data suggest that attention towards 2 other training parameters, including the intensity and variability of walking practice, may maximize walking recovery and facilitate gains in non-walking outcomes. The combination of these training parameters represents a stark contrast from traditional strategies, and confusion regarding the potential benefits and perceived risks may limit their implementation in clinical practice.
