Photodynamic therapy (PDT) holds promise as a cancer treatment modality due to its potential for enhanced therapy precision and safety. To enhance deep tissue penetration and minimize tissue adsorption and phototoxicity, developing photosensitizers activated by second near-infrared window (NIR-II) light shows significant potential. However, the efficacy of PDT is often impeded by tumor microenvironment hypoxia, primarily caused by irregular tumor vasculature.

Objective: Using rabbit models, this study simulated the laryngopharynx's response to the synergistic effects of various acidic reflux environments and pepsin to investigate the response mechanism underlying weak acid reflux and pepsin in the mucosal barrier injury of laryngopharyngeal reflux.
Methods: The rabbits were divided into six groups, and the original larynx was recorded for each group. During the study period, rabbits were sprayed with different doses of acid and pepsin solutions and monitored for hypopharyngeal mucosal transient impedance before and after modeling.

Multipalladium clusters possess peculiar structures and synergistic effects for reactivity and selectivity. Herein, -symmetric tripalladium clusters (, 0.5 mol %) afford C-regioselective SMCC of 2,4-dibromopyridine with phenylboronic acids or pinacol esters (C:C up to 98:1), in contrast to Pd(OAc) in ligand-free conditions.

Developing nonprecious metal-based electrocatalysts with exceptional activity and durability for water electrolysis remains a significant challenge. Herein, we report a highly efficient bifunctional electrocatalyst composed of sulfur-doped vanadium metal-organic frameworks (S@V-MOF) integrated with multiwalled carbon nanotubes (MWCNTs) to promote the synergistic effect between S@V-MOF and MWCNTs and modulate the electronic structure of the catalyst, which eventually enhanced its electrocatalytic performance. The S@V-MOF/MWCNT catalyst loaded at the Ni foam electrode exhibits remarkable activity for both the hydrogen evolution reaction (HER) in acidic media and oxygen evolution reaction (OER) in alkaline media, requiring overpotentials of 48 and 227 mV, respectively, to reach a current density of 10 mA cm.

Introduction: Alzheimer's disease (AD) patients with higher educational attainment (EA) often exhibit better cognitive function. However, the relationship among EA status, AD pathology, structural brain reserve, and cognitive decline requires further investigation.
Methods: We compared cognitive performance across different amyloid beta (Aβ) positron emission tomography (A ±) statuses and EA levels (High EA/Low EA).
