In this study, we developed an innovative CuSe/PDA/AIPH nanoparticle platform that combines photothermal therapy and chemotherapy for effective tumor treatment. The CuSe nanoparticles, known for their strong near-infrared (NIR) absorption, were encapsulated within a polydopamine (PDA) and 2,2'-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride (AIPH) matrix. Upon NIR irradiation, the platform triggers localized heating and subsequent thermal decomposition of AIPH, releasing ROS to induce significant oxidative damage in tumor cells.

Imidazoline receptors (I-IRs) are altered in Alzheimer's disease (AD) patients and are associated with analgesia. I-IRs are not structurally described, and their pharmacological characterization relies on their modulation by highly affine ligands. Herein, we describe the synthesis of (3-phenylcarbamoyl-3,4-dihydro-2-pyrrol-2-yl)phosphonates endowed with relevant affinities for I-IRs in human brain tissues.

Hyperthermia has emerged as a popular treatment option due to its high efficacy and seamless integration with other therapeutic approaches. To enhance treatment outcomes, hydrogels loaded with photothermal agents and activated by near-infrared (NIR) light for localized tumor therapy have attracted considerable attention. This approach minimizes drug dosage and mitigates the adverse effects of systemic drug delivery on healthy tissues.

This study aimed to investigate the effects of chronic sympathoinhibition on glucose uptake by the myocardium and by the skeletal muscle in an animal model of obesity associated with leptin signaling deficiency. 6 obese Zucker rats (OZR) and 6 control Lean Zucker rats (LZR) were studied during basal conditions, chronic clonidine administration (30 days, 300 µg/kg), and washout recovery period. Glucose uptake in the myocardium and in the skeletal muscle was measured using positron emission tomography (PET) and 2-[18F] fluoro-2-deoxy-D-glucose ([18F]FDG).
