Nrf2 Signaling Pathway: Focus on Oxidative Stress in Spinal Cord Injury.

Spinal cord injury (SCI) is a serious, disabling injury to the central nervous system that can lead to motor, sensory, and autonomic dysfunction below the injury plane. SCI can be divided into primary injury and secondary injury according to its pathophysiological process. Primary injury is irreversible in most cases, while secondary injury is a dynamic regulatory process.

Reduction of the trans-cortical vessel was associated with bone loss, another underlying mechanism of osteoporosis.

Rationale: Numerous studies have established a robust association between bone morrow microvascular diseases and osteoporosis. This study sought to investigate the relationship between alterations in trans-cortical vessel (TCVs) and the onset of osteoporosis in various mouse models.

Methods: Aged mice, ovariectomized mice, and db/db mice, were utilized as osteoporosis models.

Efficient Synthesis of Cyclic Poly(ethylene glycol)s under High Concentration Conditions by the Assistance of Pseudopolyrotaxane with Cyclodextrin Derivatives.

An efficient synthesis of cyclic polymers (CPs) is in high demand due to their unique properties. However, polymer cyclization generally occurs at low concentrations (0.1 g/L), and the synthesis of CPs at high concentrations remains a challenge.

The role of PI3K/Akt signalling pathway in spinal cord injury.

Spinal cord injury (SCI) is a severely disabling central nervous system injury with complex pathological mechanisms that leads to sensory and motor dysfunction. The current treatment for SCI is aimed at symptomatic symptom relief rather than the pathological causes. Several studies have reported that signaling pathways play a key role in SCI pathological processes and neuronal recovery mechanisms.
