Mesoscale Recovery of Microglial and Neuronal Dynamics After Craniotomy Across Wide Cortex in Transgenic Mice

open access: yesAdvanced Science, EarlyView.
This study employs longitudinal fluorescence imaging in transgenic mice to map post‐craniotomy cortical recovery. We identify distinct neuroimmune recovery phases: microglial structural inflammation peaks at ∼10 days, neuronal structural intensity peaks at ∼14 days and correlates with microglial activity, and functional network modularity is most ...

CRP Deficiency Rescues Periodontitis‐Induced Hippocampal Neurogenesis Impairment by Suppressing OPC‐Derived BMP4 Signaling in Rats

open access: yesAdvanced Science, EarlyView.
Chronic periodontitis elevates circulating CRP, which enters the hippocampus to upregulate BMP4 in oligodendrocyte precursor cells (OPCs), thereby impairing neurogenesis and inducing anxiety/depression‐like behaviors in rats. Counteracting this pathway, CRP deficiency helps confer functional resilience to OPCs.

Malignant perivascular epithelioid cell tumor (PEComa) of the uterus with late renal and pulmonary metastases: a case report with review of the literature [PDF]

open access: yes, 2007
Background Perivascular epithelioid cell tumor (PEComa), other than angiomyolipoma (AML), clear cell sugar tumor (CCST), and lymphangioleiomyomatosis (LAM), is a very rare mesenchymal tumor with an unpredictable natural history.

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

open access: yesAdvanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Chondroid chordoma of the parapharyngeal space: A case report and review of literature

open access: yesActa Oto-Laryngologica Case Reports, 2020
Parapharyngeal space (PPS) tumors are a rare entity and account for less than 1% of all head and neck tumors. Although they exhibit a benign behavior, malignant neoplasms may arise from any of the structure contained in the space.

Intracranial chordoma presenting as acute hemorrhage in a child: Case report and literature review [PDF]

open access: yes, 2015
BACKGROUND: Chordomas are rare, slow-growing malignant neoplasms derived from remnants of the embryological notochord. Pediatric cases comprise only 5% of all chordomas, but more than half of the reported pediatric chordomas are intracranial.

A LDH‐Based Supramolecular Photosensitizer‐Functionalized Bioactive Glass Scaffold for Integrated Postoperative Osteosarcoma Recurrence Prevention and Bone Regeneration

open access: yesAdvanced Science, EarlyView.
An intercalation assembly strategy is proposed to construct a novel LDH‐based supramolecular photosensitizer, which exhibits outstanding reactive oxygen species generation activity under 1270 nm laser irradiation. The deposition of supramolecular photosensitizer onto the surface of bioactive glass scaffolds results in the development of an innovative ...
