Background: This experimental study was performed to investigate the benefit of curcumin via its antioxidant effect on spinal cord injury (SCI) in rats.
Methods: Twenty-four adult Wistar albino rats were randomized into three groups. SCI was performed by the weight-drop model. Group 1 underwent laminectomy followed by SCI and received no medication. Group 2 underwent laminectomy followed by SCI and received curcumin (200 mg/kg/day orally). Group 3 underwent laminectomy followed by SCI and received methylprednisolone (30 mg/kg intraperitoneally). Twenty-four hours later, blood samples were obtained from all rats; serum superoxide dismutase (SOD) and malondialdehyde (MDA) levels were determined, and the obtained results were compared.
Results: SOD level in the curcumin group was higher than in the control group (p < 0.000) and methylprednisolone group (p < 0.012). MDA level in the curcumin group was lower than in the control group (p < 0.042). Similarly, the MDA level in the methylprednisolone group was lower than in the control group (p < 0.001).
Conclusion: The results of the present study show that curcumin effectively protects the spinal cord tissues against oxidative damage.

Objectives: Rehabilitation services are crucial for improving the quality of life and overall health of individuals with spinal cord injuries (SCIs). However, access to adequate rehabilitation remains limited in many regions, including Iran. This study aims to explore the barriers faced by individuals with SCIs in accessing appropriate rehabilitation services within Golestan province, northern of Iran.

Purpose: In congenital scoliosis, the surgical strategy approach of hemivertebra excision, with or without instrumentation and fusion, is a common approach to correction of scoliosis. However, hemivertebra excisions are technically challenging, with potential complications including spinal cord injury, nerve root injury and cerebrospinal fluid leak. The purpose of this study was to determine whether correction of congenital scoliosis can be achieved using a posterior instrumentation/fusion-only approach without the need for hemivertebra excision.

Ferroptosis is one of the cell death programs occurring after spinal cord injury (SCI) and is driven by iron-dependent phospholipid peroxidation. However, little is known about its underlying regulation mechanism. The present study demonstrated that lipid peroxidation was promoted in patients with SCI.

Lower urinary tract symptoms (LUTS) significantly affect patient quality of life. Treatment options for bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH) (a common cause of LUTS) are insufficient to relieve discomfort. As the incidence of BPH is increasing, new pharmacological targets for LUTS treatment are required.

Creating durable, motion-compliant neural interfaces is crucial for accessing dynamic tissues under in vivo conditions and linking neural activity with behaviors. Utilizing the self-alignment of nano-fillers in a polymeric matrix under repetitive tension, here, we introduce conductive carbon nanotubes with high aspect ratios into semi-crystalline polyvinyl alcohol hydrogels, and create electrically anisotropic percolation pathways through cyclic stretching. The resulting anisotropic hydrogel fibers (diameter of 187 ± 13 µm) exhibit fatigue resistance (up to 20,000 cycles at 20% strain) with a stretchability of 64.
