Phase 2-3 Trial: Prevention of the Progression to Moderate and Severe COVID-19 in SARS-CoV-2-Infected Non-Hospitalized Adults With Inhaled siRNA-Based MIR 19.

Background: COVID-19 continues to be a major global health challenge. Inhaled siRNA-based MIR 19 has been shown to reduce the time to clinical improvement in patients hospitalized with moderate COVID-19.

Methods: We conducted an open-label, randomized, controlled multicenter phase 2b-3 trial (NCT05783206) evaluating the safety and efficacy of inhaled siR-7-EM/KK-46 (MIR 19) (5.

Search for New Resonances Decaying to Pairs of Merged Diphotons in Proton-Proton Collisions at sqrt[s]=13 TeV.

A search is presented for an extended Higgs sector with two new particles, X and ϕ, in the process X→ϕϕ→(γγ)(γγ). Novel neural networks classify events with diphotons that are merged and determine the diphoton masses. The search uses LHC proton-proton collision data at sqrt[s]=13  TeV collected with the CMS detector, corresponding to an integrated luminosity of 138  fb^{-1}.

Development of Ketoprofen Impurity A (1-(3-Benzoylphenyl)ethanone) as a Certified Reference Material for Pharmaceutical Quality Control.

: Reference materials are essential for ensuring the accuracy and traceability of measurements in the quality control of medicinal products. This study explores new principles for the preparation of impure materials of active pharmaceutical substances, focusing on 1-(3-benzoylphenyl)ethanone ketoprofen impurity A () as the reference material. : The reference material was synthesised from commercially available acetanilide and benzoyl chloride.

Texture Perception and Chewing of Agar Gel by People with Different Sensitivity to Hardness.

Hardness is one of the dominant sensory characteristics of food. This study estimated the effect of sensitivity to hardness on the texture perception and chewing function using 2, 4, and 6% agar gels. Increasing the concentration of agar resulted in an increase in gel hardness and springiness, measured by texture profile analysis.

Nanoscale Titanium Oxide Memristive Structures for Neuromorphic Applications: Atomic Force Anodization Techniques, Modeling, Chemical Composition, and Resistive Switching Properties.

This paper presents the results of a study on the formation of nanostructures of electrochemical titanium oxide for neuromorphic applications. Three anodization synthesis techniques were considered to allow the formation of structures with different sizes and productivity: nanodot, lateral, and imprint. The mathematical model allowed us to calculate the processes of oxygen ion transfer to the reaction zone; the growth of the nanostructure due to the oxidation of the titanium film; and the formation of TiO, TiO, and TiO oxides in the volume of the growing nanostructure and the redistribution of oxygen vacancies and conduction channel.
