Arterial Perivascular Space‐Mediated Solute Transport in the Mouse Brain

Exploration, EarlyView.
The mechanisms underlying solute clearance from the brain parenchyma remain debated, with competing hypotheses involving bulk cerebrospinal fluid flow versus perivascular transport. Using multimodal in vivo imaging and computational modeling in mice, this study demonstrates that arterial pulsation drives bidirectional solute movement within the ...

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Different Pattern of Treatment Failure After Chemoradiation Between p16+ and p16− Patients Affected by Oropharyngeal Carcinoma

Head &Neck, EarlyView.
ABSTRACT Background Oropharyngeal cancer (OPC) exhibits distinct clinical behaviors according to HPV/p16 status and smoking exposure. While HPV‐positive OPC generally shows superior survival, differences in recurrence patterns remain unclear. Methods A retrospective multicenter analysis of 674 AJCC VII edition Stage III–IVa/b OPC patients treated with ...

Intraoperative Indocyanine Green Fluorescence Enables Primary Tumor Localization and Treatment De‐Escalation in SCCUP: A Case Report

Head &Neck, EarlyView.
ABSTRACT Background Unknown primary cancer in the head and neck presents a difficult surgical treatment dilemma. Patients with squamous cell carcinoma of unknown primary (SCCUP) typically present with an enlarging neck mass found on biopsy but with no indication of primary site on diagnostic exams such as flexible laryngoscopy, CT, MRI, and/or PET/CT ...
