We used formalin-fixed human spinal cord and dorsal root ganglia as immunogens to generate monoclonal antibodies (mAb) which immunohistochemically react with neurons in formalin-fixed human tissue sections. Three of the mAb recognized all neuronal populations studied, including those in spinal cord, dorsal root ganglia, cerebellum, and cerebrum. A fourth mAb recognized neurons within spinal cord, dorsal root ganglia and dentate nucleus of cerebellum but not those in cerebrum or cerebellar hemispheres. This mAb, unlike the other three, did not recognize murine neurons. These data indicate the feasibility of generating mAb suitable for analysis of human pathological material in its most readily available form, formalin-fixed paraffin-embedded tissue.

Delayed Neurological Deficits Following Lumbar 1 Burst Fracture: A Diagnostic Challenge Without Radiological Correlates.

Spinal cord injuries, including rare cases without radiological abnormalities, pose diagnostic challenges, particularly in cases of delayed neurological deficit development. This case report describes a 55-year-old man with a stable L1 burst fracture who developed delayed neurological deficits two weeks after sustaining a fall despite no evidence of intrinsic or extrinsic spinal cord abnormalities on magnetic resonance imaging (MRI). The patient initially presented with back pain, normal muscle strength across all myotomes, and imaging that showed no canal stenosis or retropulsion fragments.

Biomimetic neural substitutes, constructed through the bottom-up assembly of cell-matrix modulus via 3D bioprinting, hold great promise for neural regeneration. However, achieving precise control over the fate of neural stem cells (NSCs) to ensure biological functionality remains challenging. Cell behaviors are closely linked to cellular dynamics and cell-matrix mechanotransduction within a 3D microenvironment.

Despite advancements in surgical techniques and critical care, managing complications of type A and B aortic dissections remains challenging. Common morbidities include paraplegia, renal failure, stroke, and intestinal ischemia. Risks are especially high in extensive repairs, such as Crawford extent II thoracoabdominal aortic aneurysms, and in older patients or those with heart failure, poor pulmonary function, or renal disease.

Spinal cord injury (SCI) is a severe condition that often leads to permanent functional impairments. The current treatment options are limited and there is a need for more effective treatments. Human umbilical cord mesenchymal stem cells (hUCMSCs) have shown promise in promoting neuroregeneration and modulating immune response.
