A Silver Lining of Neuropathic Pain: Predicting Favorable Functional Outcome in Spinal Cord Injury.

Background: Neuropathic pain (NP) is a common and severe problem following spinal cord injury (SCI). However, its relationship with functional outcome remains unclear.

Methods: A retrospective explorative analysis was performed on SCI patients admitted to a tertiary academic medical center between January 2018 and June 2022.

Primary motor hand area corticospinal excitability indicates overall functional recovery after spinal cord injury.

Background: After spinal cord injury (SCI), the excitability of the primary motor cortex (M1) lower extremity area decreases or disappears. A recent study reported that the M1 hand area of the SCI patient encodes the activity information of both the upper and lower extremities. However, the characteristics of the M1 hand area corticospinal excitability (CSE) changes after SCI and its correlation with extremities motor function are still unknown.

Neuropathic Pain: the Dysfunction of Drp1, Mitochondria, and ROS Homeostasis.

Neuropathic pain affects the physical and mental health status of patients. Due to its complex pathogenesis and the adverse reactions to medicines, its treatment remains challenging. Among all the etiologies, increasing evidence has pointed to mitochondrial dysfunction.

Drp1 is widely, yet heterogeneously, distributed in the mouse central nervous system.

Objectives: Drp1 is widely expressed in the mouse central nervous system and plays a role in inducing the mitochondrial fission process. Many diseases are associated with Drp1 and mitochondria. However, since the exact distribution of Drp1 has not been specifically observed, it is difficult to determine the impact of anti-Drp1 molecules on the human body.

Lentiviral Vectors and Adeno-Associated Virus Vectors: Useful Tools for Gene Transfer in Pain Research.

Pain, especially chronic pain, has always been a heated point in both basic and clinical researches since it puts heavy burdens on both individuals and the whole society. A better understanding of the role of biological molecules and various ionic channels involved in pain can shed light on the mechanism under pain and advocate the development of pain management. Using viral vectors to transfer specific genes at targeted sites is a promising method for both research and clinical applications.

p53 and mitochondrial dysfunction: novel insight of neurodegenerative diseases.

Mitochondria are organelles responsible for vital cell functions. p53 is a transcription factor that regulates the DNA stability and cell growth normality. Recent studies revealed that p53 can influence mitochondrial function changing from normal condition to abnormal condition under different stress levels.
