Magneto‐NIR‐II‐Programmed Cascade Nanozymes Unlocking Blood–Brain Barrier Translocation and Autophagic Resistance in Glioblastoma

Advanced Science, EarlyView.
Magneto‐NIR‐II‐programmed NFSH nanozymes integrate magnetic blood–brain barrier (BBB) translocation, CD44 targeting, multimodal imaging, and cascade catalytic therapy for glioblastoma. Alternating magnetic fields and NIR‐II irradiation amplify ferroptosis, release H2S, suppress autophagic and mitophagic repair, and reshape the immune microenvironment ...

The radiological and histopathological differential diagnosis of chordoid neoplasms in skull base

Chinese Journal of Contemporary Neurology and Neurosurgery, 2013
Background Chordoid neoplasms refer to tumors appearing to have histological features of embryonic notochord, which is characterized by cords and lobules of neoplastic cells arranged within myxoid matrix.

Skull base plasmacytoma in a patient with light chain myeloma

, 2003
Skull base involvement of plasmacytoma is reported in a patient with light chain myeloma. A 39-year-old man was admitted after experiencing paresthesia on the left side of the face and left arm, intermittent diplopia, and hoarseness for 2 years.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

Advanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Microvascular tissue transfer in reconstruction of anterior skull base defects secondary to sinonasal malignancies: a case series and proposed reconstructive framework

Egyptian Journal of Neurosurgery
Sinonasal malignancies such as lymphoepithelial carcinoma (LEC) and esthesioneuroblastoma (ENB) are rare but aggressive neoplasms that frequently necessitate extensive resection of anterior skull base structures, creating complex defects.

Machine Learning‐Driven Design of Multicomponent Bone Inorganic Matrix Mimicking Scaffolds for Osteogenesis Enhanced by Neurogenesis

Advanced Science, EarlyView.
Schematic illustration of development of experimental datasets and algorithm models, screening and preparation of the scaffolds and their applications in vivo. ABSTRACT Bone defects require materials with osteogenic, neurogenic, and angiogenic activity, yet designing such materials within high‐dimensional compositional spaces remains challenging. Here,

The role of midfacial degloving in modern rhinological practice [PDF]

, 1999
The midfacial degloving approach has been available for twenty five years and is slowly increasing in popularity in the management of extensive benign lesions of the sinonasal region, for selected malignancy in this area and to afford access to the ...

Clonal Composition of Human Adrenocortical Neoplasms [PDF]

, 1994
The mechanisms of tumorigenesis of adrenocortical neoplasms are still not understood. Tumor formation may be the result of spontaneous transformation of adrenocortical cells by somatic mutations.

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

Acta 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.
