Primary Non-Hodgkin's Malignant Lymphoma of the Sinonasal Tract [PDF]

open access: yes, 2009
Primary non-Hodgkin’s lymphomas (NHL) of the sinonasal tract are rather uncommon entities. Morphologically and radiographically, sinonasal lymphomas are difficult to distinguish from other malignant neoplasms or non- neoplastic processes.

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.

Pinosylvin Inhibits Inflammatory and Osteoclastogenesis via NLRP3 Inflammasome

open access: yesAdvanced Science, EarlyView.
Pinosylvin blocks LPS and RANKL induced NEK7/NLRP3 interaction, inhibiting NLRP3 inflammasome oligomerization and assembly, reducing IL‐1β maturation and GSDMD cleavage, and improving the inflammatory microenvironment and abnormal osteoclastogenesis. Abstract Pro‐inflammatory cytokines such as TNF, IL‐1, and IL‐6 trigger aberrant osteoclastogenesis and

Intracranial transplantation of the tumor induced by adenovirus type 12 in Syrian hamster--an experimental brain tumor model [PDF]

open access: yes, 1971
A method of intracranial transplantation of the tumor induced by adenovirus type 12 in syrian hamster has been described. The incidence of intracranial tumor development was 86 (90.5 %) out of 95 animals and the average survival time and tumor size at ...

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

open access: yesAdvanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

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.

Natural History of Acute Subdural Hematoma [PDF]

open access: yes, 2017
Although guidelines for surgical decision-making in patients with acute subdural hematomas (ASDHs) are widely available, the evidence supporting these guidelines is weak, and management of these patients must often be individualized.

Sleep Deprivation Activates a Conserved Lactate‐H3K18la‐RORα Axis Driving Neutrophilic Inflammation Across Species

open access: yesAdvanced Science, EarlyView.
Sleep deprivation triggers systemic immune activation characterized by neutrophil accumulation and cytokine release. This study reveals a conserved metabolic‒epigenetic mechanism whereby lactate‐induced H3K18 lactylation upregulates RORα expression, promoting neutrophilic inflammation.

Skull base chordomas review of current treatment paradigms

open access: yesWorld Journal of Otorhinolaryngology-Head and Neck Surgery, 2020
Background: Chordomas are locally invasive neoplasms, arising from notochordal remnants and can appear anywhere along the axial skeleton. Local recurrences are common, and distant metastases may occur years after the initial presentation.
