Unusual appearance of spontaneous spinal intradural hematoma mimicking a meningioma

Radiology Case Reports
Spontaneous spinal intradural hematoma is uncommon. It can mimic vascular or hemorrhagic neoplasms, as certain imaging features overlap. The distinction between spinal hematoma and neoplasm is crucial for the approach to management and might determine ...

Synovial Fluid‐derived Micrococcus Luteus G18 Exacerbates Osteoarthritis Progression by Promoting Chondrocyte Degradation via TLR2/JNK/AP‐1 Signaling Pathway

Advanced Science, EarlyView.
Traditionally considered sterile, the articular cavity is now recognized to harbor microbial communities influencing osteoarthritis (OA). Integrating 16S rRNA sequencing and culturomics, Micrococcus luteus is enriched in advanced OA. Notably, M. luteus G18 exacerbates cartilage degeneration via TLR2/JNK/AP‐1‐mediated ECM disruption, revealing intra ...

Targeting Microglial CD49a Inhibits Neuroinflammation and Demonstrates Therapeutic Potential for Parkinson's Disease

Advanced Science, EarlyView.
This study shows that integrin receptor CD49a (Itga1 gene) is significantly upregulated in hyperactivated microglia and microglia‐specific knockdown of Itga1 rescues neuroinflammation and neurodegeneration in a chronic Parkinson's disease (PD) model by targeting PGAM5‐mediated mitochondrial dysfunction and NLRP3 activation. Targeted inhibition of CD49a

Esketamine/Ketamine: Dual‐Action Mechanisms and Clinical Prospects beyond Anesthesia in Psychiatry, Immunology, and Oncology

Advanced Science, EarlyView.
Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.

Spinal neoplasm in dogs

, 2018
Background: Various diseases can cause spinal cord disorders in dogs including neoplasia of the nervous system, which are more common in mature and older animals. Some breeds, as brachycephalics, are more predisposed for certain types of tumors.

Alkaline Phosphatase‐Activated NIR‐II AIEgens Nanosystem for Surgical and Postoperative Closed‐Loop Therapy of Advanced Osteosarcoma

Advanced Science, EarlyView.
This study designed a tumor microenvironment‐responsive AIEgen nanoparticle for near‐infrared photoimmunotherapy, which inhibits primary tumors and metastasis by promoting pyroptosis and suppressing aerobic glycolysis. ABSTRACT In advanced osteosarcoma, tumor invasion often prevents complete resection, and immunotherapy is limited by the tumor's ...

Disrupting CSPG‐Driven Microglia–Astrocyte Crosstalk Enables Scar‐Free Repair in Spinal Cord Injury

Advanced Science, EarlyView.
This study identifies CSPGs as key drivers of glial scar maturation after spinal cord injury by reprogramming microglial metabolism and inducing astrocyte fibrosis. To address this, a reactive oxygen species‐responsive, reactive astrocyte‐targeted ChABC gene delivery system is designed to locally degrade CSPGs, precisely disrupt maladaptive glial ...

CRISPLD2 Attenuates Intervertebral Disc Degeneration by Suppressing Oxidative Stress‐Induced Ferroptosis through the miR‐548I‐IL17A Axis

Advanced Science, EarlyView.
This study identifies CRISPLD2 as a key protector against IVDD. By regulating ferroptosis through the CRISPLD2–miR‐548I–IL17A axis, CRISPLD2 maintains NPCs homeostasis and reduces oxidative stress. Restoring CRISPLD2 expression effectively alleviates disc degeneration and highlights a promising therapeutic strategy for discogenic low back pain ...
