Article Abstract
To fabricate a novel stimuli-responsive system enabling controlled drug release and synergistic therapy, yolk-shell shaped bismuth sulfide modified with Au nanoparticles (Au-BiS) was prepared. The Au-BiSnanomaterial with heterojunction structure exhibited excellent photothermal conversion efficiency and considerable free radicals yield under laser irradiation. The drug delivery capacity was confirmed by co-loading Berberine hydrochloride (BBR) and a phase change material 1-tetradecanol (PCM), which could be responsible for NIR light induced thermal controlled drug release.investigation demonstrated that Au-BiShas cell selectivity, and with the assistance of the properties of Au-BiS, the loaded drug could give full play to their cancer cell inhibition ability. Our work highlights the great potential of this nanoplatform which could deliver and control Berberine hydrochloride release as well as realize the synergistic anti-tumor strategy of photothermal therapy, photodynamic therapy and chemotherapy for tumor therapy.

High-Intensity Exercise and Hippocampal Integrity in Adults With Cannabis Use Disorder: A Randomized Clinical Trial.
JAMA Psychiatry
September 2025
School of Psychological Sciences, Monash University, Melbourne, Victoria, Australia.
Importance: Cannabis is the most commonly used illicit drug, with 10% to 30% of regular users developing cannabis use disorder (CUD), a condition linked to altered hippocampal integrity. Evidence suggests high-intensity interval training (HIIT) enhances hippocampal structure and function, with this form of physical exercise potentially mitigating CUD-related cognitive and mental health impairments.
Objective: To determine the impact of a 12-week HIIT intervention on hippocampal integrity (ie, structure, connectivity, biochemistry) compared with 12 weeks of strength and resistance (SR) training in CUD.
ANK3 as a Novel Genetic Biomarker for Liafensine in Treatment-Resistant Depression: The ENLIGHTEN Randomized Clinical Trial.
JAMA Psychiatry
September 2025
Denovo Biopharma LLC, San Diego, California.
Importance: This study represents a first successful use of a genetic biomarker to select potential responders in a prospective study in psychiatry. Liafensine, a triple reuptake inhibitor, may become a new precision medicine for treatment-resistant depression (TRD), a major unmet medical need.
Objective: To determine whether ANK3-positive patients with TRD benefit from a 1-mg and/or 2-mg daily oral dose of liafensine, compared with placebo, in a clinical trial.

Colorectal cancer (CRC) remains a major global health burden, necessitating more effective and selective therapeutic approaches. Nanocarrier-based drug delivery systems offer significant advantages by enhancing drug accumulation in tumors, reducing off-target toxicity, and overcoming resistance mechanisms. This review provides a comprehensive overview of recent advancements in nanocarriers for CRC therapy, including passive targeting the enhanced permeability and retention (EPR) effect, and active targeting strategies that exploit specific tumor markers using ligands such as antibodies, peptides, and aptamers.

Department of Optometry and Vision Sciences, The University of Melbourne, Melbourne, Australia.
Purpose: To characterize corneal immune cell morphodynamics and nerve features, and define the in vivo immune landscape in older adults with human immunodeficiency virus (HIV) receiving antiretroviral therapy (ART), relative to healthy age-matched adults.
Methods: In this cross-sectional study, 16 HIV-positive individuals receiving ART and 15 age-matched controls underwent ocular surface examinations and functional in vivo confocal microscopy (Fun-IVCM). Time-lapsed videos were created to analyze corneal immune cells (T cells, dendritic cells [DCs], macrophages).
