Preoperative Metabolic Predictors of Granulation Subtypes in Somatotroph Tumors: A Multicenter Retrospective Cohort Study

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 2, February 2026.
Somatotroph tumors, a rare subtype of pituitary adenomas, can be histologically classified into sparsely granulated (SGSTs) and densely granulated somatotroph tumors (DGSTs) based on cytokeratin staining. SGSTs are generally more invasive and less responsive to medical therapy, making their early identification clinically important.

Prelacrimal Recess‐Pterygoid Window Approach to the Sphenoidal Lateral Recess Skull Base Defects

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 1, Page 66-76, February 2026.
ABSTRACT Objective The objectives of this study are: (1) to evaluate the prelacrimal recess‐pterygoid window approach (PLR‐PWA) for treating cerebrospinal fluid leaks and meningoencephaloceles (CSFLME) in the sphenoidal lateral recess (SLR). (2) To investigate the pneumatization of the SLR and its relationship with surrounding structures, including the

Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.
