Reversible Electrocatalytic NAD/NADH Interconversion Mediated by a Pyrazine-Amidate Iridium Complex.
J Am Chem Soc

Department of Chemistry, Biology, and Biotechnology, Università degli Studi di Perugia, Via Elce di Sotto 8, 06123 Perugia, Italy.
Herein, we report reversible electrocatalytic NAD/NADH interconversion mediated by [Cp*Ir(pyza)Cl] (, pyza = pyrazine amidate). was designed through a rational approach aimed at lowering the overpotential of NAD to NADH reduction with respect to that observed for electrocatalyst [Cp*Ir(pica)Cl] (, pica = picolinamidate). The peculiar properties of pyza, which is substantially less σ electron-donator and more π electron-acceptor than pica, resulted in an easier bielectronic reduction process occurring at -0.

Article Synopsis
- Self-expanding Y-metal stents (SEMS) are useful for treating complex airway lesions, but their placement can be challenging; the study introduces a modified method called the Y reverse technique to improve stent insertion.
- The research involved 15 patients with airway issues, where only those with specific conditions were treated using this new technique.
- Results showed that the Y reverse technique enhanced respiratory function, increased mean survival times, and reduced procedure duration when compared to traditional methods, indicating it to be a safe and effective treatment for airway obstruction.
Functional ecological traits in young and adult thalli of canopy-forming brown macroalga (Phaeophyta) from a transitional water system.

Department of Biology, University of Naples Federico II, Naples, Italy.
Background: is a canopy-forming brown macroalga that thrives in the intertidal and subtidal habitats of the warm-temperate Mediterranean Sea, which is particularly exposed to environmental changes due to its peculiar geographical location and exposure to both global and local stressors. Testing whether this species is featured by specific functional, eco-physiological and biochemical traits allowing an efficient use of habitat resources and adaptation to environmental stress, and whether this potential might change with population growth, is essential for predicting the performance of the algae under different environmental abiotic variables (, temperature, nutrient availability, light) and biotic interactions (such as grazing).
Methods: Young (juveniles) and adult thalli of were sampled in the winter season from the Venice Lagoon, Italy, featured by high environmental changes (temperature, salinity) and analyzed for thallus dry matter content (TDMC), photosynthetic activity, photosynthetic pigment and protein content, and antioxidant capacity to assess if thallus age may be considered a significant driver in determining the ecological responses of this species to environmental changes.
Deciphering the Novel Picolinate-Mn(II)/peroxymonosulfate System for Sustainable Fenton-like Oxidation: Dominance of the Picolinate-Mn(IV)-peroxymonosulfate Complex.

A highly efficient and sustainable water treatment system was developed herein by combining Mn(II), peroxymonosulfate (PMS), and biodegradable picolinic acid (PICA). The micropollutant elimination process underwent two phases: an initial slow degradation phase (0-10 min) followed by a rapid phase (10-20 min). Multiple evidence demonstrated that a PICA-Mn(IV) complex (PICA-Mn(IV)*) was generated, acting as a conductive bridge facilitating the electron transfer between PMS and micropollutants.

Department of Anesthesiology, The First Affiliated Hospital of Jinan University, Guangzhou, China.
Objective: Patients with Postherpetic Neuralgia (PHN) often exhibit depressive-like symptoms, significantly impacting their quality of life. Esketamine, known for its analgesic properties, has also been recognized for its rapid antidepressant effects. However, its efficacy in the treatment of PHN requires further exploration.
