Computed tomography-based absolute delta radiomics nomogram for predicting perineural invasion in hypopharyngeal squamous cell carcinoma.

Objective: To assess the efficacy of computed tomography (CT)-based radiomics nomogram in predicting perineural invasion (PNI) in patients with hypopharyngeal squamous cell carcinoma (HPSCC).

Materials And Methods: Overall, 146 patients were retrospectively recruited and divided into training and test cohorts at a 7:3 ratio. Radiomics features were extracted and delta and absolute delta radiomics features were calculated.

Cu-doped waste-tire carbon as catalyst for UV/HO oxidation of ofloxacin.

Ofloxacin (OFX), commonly employed in the treatment of infectious diseases, is frequently detected in aquatic environments and poses potential ecological risks. UV/HO oxidation has been recognized as an efficient approach for removing antibiotics. In this study, Cu-doped waste-tire carbon was prepared and used as a UV/HO catalyst for the degradation of OFX.

Single Extracellular VEsicle Nanoscopy-Universal Protocol (SEVEN-UP): Accessible Imaging Platform for Quantitative Characterization of Single Extracellular Vesicles.

Extracellular vesicles (EVs), membrane-encapsulated nanoparticles shed from all cells, are tightly involved in critical cellular functions. Moreover, EVs have recently emerged as exciting therapeutic modalities, delivery vectors, and biomarker sources. However, EVs are difficult to characterize, because they are typically small and heterogeneous in size, origin, and molecular content.

MAIT cell deficiency exacerbates neuroinflammation in P301S human tau transgenic mice.

The role of immune cells in neurodegeneration remains incompletely understood. Our recent study revealed the presence of mucosal-associated invariant T (MAIT) cells in the meninges, where they express antioxidant molecules to maintain meningeal barrier integrity. Accumulation of misfolded tau proteins are a hallmark of neurodegenerative diseases.
