Ultrasound-Activated Copper Matrix Nanosonosensitizer for Cuproptosis-Based Synergy Therapy.
ACS Appl Bio Mater

State Key Laboratory of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210023, P. R. China.
Cuproptosis exhibits enormous application prospects in treatment. However, cuproptosis-based therapy is impeded by the limited intracellular copper ions, the nonspecific delivery, uncontrollable release, and chelation of endogenous overproduced glutathione (GSH). In this work, an ultrasound-triggered nanosonosensitizer (p-TiO-Cu(I)) was constructed for Cu(I) delivery, on-demand release, GSH consumption, and deeper tissue response.

Dark-field and confocal approaches to circular dichroism (CD) spectroscopy of uniaxial thin films examine the relationship between symmetry and incoherence in the nonreciprocal CD response, or the component that is antisymmetric about the light propagation direction. Modifying a conventional CD spectrometer for low-angle scattering detection isolates incoherent contributions to nonreciprocal CD of drop-cast thin films, boasting 5-to-10-fold enhancements in CD dissymmetry parameters. Conversely, confocal detection suppresses the nonreciprocal CD response.

Cardiology Department (P.B., X.L., V.T.T., M.A.B., A.V., E.Y., D.M.N., U.P., J.L., S.P.T., P.C.Q.), Westmead Hospital, Sydney, Australia.
Background: Transcatheter renal denervation (RDN) remains inconsistent despite developments in ablation technologies, due to the lack of an intraprocedural physiological end point.
Objective: To identify whether aorticorenal ganglion (ARG) guided RDN using microwave (MW) catheter leads to more consistent denervation outcomes compared with empirical MW ablation.
Methods: Pigs underwent sham procedure (n=8) or bilateral RDN using an in-house built open-irrigated MW catheter.
Microiontophoretic Application of Dynorphin in Dental Pain: Excitatory or Inhibitory Effects.
J Pain Res
January 2025
Department of Oral Physiology, School of Dentistry, Kyungpook National University, Daegu, Korea.
Background: The tooth exhibits increased sensitivity to noxious stimuli due to the dense innervation of thin myelinated Aδ fibers and unmyelinated C fibers within the dental pulp. While prior research has identified dynorphin expression in layers I-II of the dorsal horn across the spinal cord in various pain models, its functional role in trigeminal nociception, including tooth pain, remains underexplored. This study examines the potential role of dynorphin in the nociceptive processing of dental stimuli.

Consumption of plant-based food is steadily increasing and follows an augmented trend owing to their nutritive, functional, and energy potential. Different bioactive fractions, such as phenols, flavanols, and so on, contribute highly to the nutritive profile of food and are known to have a sensitivity toward higher temperatures. This limits the applicability of traditional thermal treatments for plant products, paving the way for the advancement of innovative and non-thermal techniques such as pulsed electric field, microwave, ultrasound, cold plasma, and high-pressure processing.
