A traumatic spinal cord injury (SCI) induces a sequelae of events which conduce biochemical and cellular alterations. Here we compare the degree of spinal cord injury caused by the application of vascular clips, in mice lacking the 5-lipoxygenase and in the corresponding wild-type mice. Biochemical, immunohistochemical and functional studies revealed respectively an increase of neutrophils infiltration, of IL-1beta, TNF-alpha immunoreactivity, apoptosis (measured by Annexin-V staining) and loss of hind legs movement in SCI operated 5-LO wild-type mice. In contrast, the degree of (1) neutrophil infiltration at different time points, (2) cytokine expression (TNF-alpha and IL-1beta), (3) histological damage, (4) apoptosis, was markedly reduced in the tissues obtained from SCI operated 5-LO deficient mice and (5) the motor recovery was ameliorated.

Chronic complete spinal cord injury (SCI) is difficult to treat because of scar formation and cavitary lesions. While human iPS cell-derived neural stem/progenitor cell (hNS/PC) therapy shows promise, its efficacy is limited without the structural support needed to address cavitary lesions. Our study investigated a combined approach involving surgical scar resection, decellularized extracellular matrix (dECM) hydrogel as a scaffold, and hNS/PC transplantation.

This study aimed to identify imaging risk factors for spinal cord injury without radiologic abnormalities (SCIWORA) in children. We retrospectively analyzed the medical records and magnetic resonance imaging (MRI) findings of children with SCIWORA admitted to our hospital between January 1, 2012, and September 30, 2022. Univariate and binary logistic regression analyses were used to evaluate the prognostic impact of various factors including MRI type, maximum cross-sectional area of spinal cord injury, injury length, injury signal intensity ratio.

Visual hallucinations (VH) and pareidolia, a type of minor hallucination, share common underlying mechanisms. However, the similarities and differences in their brain regions remain poorly understood in Parkinson's disease (PD). A total of 104 drug-naïve PD patients underwent structural MRI and were assessed for pareidolia using the Noise Pareidolia Test (NPT) were enrolled.

Introduction: Traumatic injury is the leading cause of pediatric mortality and morbidity in the United States. While behavioral impairments of children after traumatic brain injury (TBI) have been described, outcomes following traumatic spinal cord injury (SCI) and multi-trauma (MT) are less known. We aimed to address the prevalence of behavioral and neuropsychiatric disorders in pediatric and adolescent trauma patients.
