Objective And Importance: The use of intrathecal morphine has been effective with few complications for chronic intractable pain of both benign and malignant origins. A rare but serious problem that exists is the formation of an inflammatory mass at the catheter tip of the pain pump.
Clinical Presentation: We report the case of a 67-year-old female patient with failed back syndrome who presented with sensory complaints and back pain.
Intervention: Magnetic resonance imaging revealed impingement on the thoracic cord by a mass. The mass was originally thought to be a spinal cord tumor; however, operation and chemical analysis of the mass showed that it was a bupivacaine precipitate at the tip of the catheter of the pain pump.
Conclusion: This is the first such case, to our knowledge, of a bupivacaine precipitate mimicking a spinal cord tumor.

Background: Astrocytes, a major glial cell in the central nervous system (CNS), can become reactive in response to inflammation or injury, and release toxic factors that kill specific subtypes of neurons. Over the past several decades, many groups report that reactive astrocytes are present in the brains of patients with Alzheimer's disease, as well as several other neurodegenerative diseases. In addition, reactive astrocyte sub-types most associated with these diseases are now reported to be present during CNS cancers of several types.

Therefore, DYRK1A has been regarded as a novel target for neurodegenerative diseases. However, developing DYRK1A selective inhibitors has been a difficult challenge due to the highly conserved ATP-binding site of protein kinases, particularly among the CMGC family.

"Dual Perspectives" integrates multiple MRI scans, creating a nuanced synthesis of grey matter and diffusion-based regional connections. This rendering holds particular significance in the realm of Alzheimer's and dementia research by offering a comprehensive examination of data crucial for understanding these complex neurodegenerative conditions. The inclusion of grey matter provides a detailed insight into the structural composition of the brain.

The purpose of this study was to investigate the effects of weight- and non-weight-bearing exercises on the Basso-Beattie-Bresnahan (BBB) locomotor rating scale, corticospinal axon regrowth and regeneration-related proteins following spinal cord injury (SCI). Twenty-four male Sprague-Dawley rats were randomly divided into four groups: control group (n=6), SCI+sedentary group (SED, n=6), SCI+treadmill exercise group (TREAD, n=6), and SCI+swimming exercise group (SWIM, n=6). All rats in the SCI group were given the rest for 2 weeks after SCI, and then they were allowed to engage in low-intensity exercise for 6 weeks on treadmill device.
