Differentiation of the Cytokine Profile Modified by SARS-CoV-2 and Influenza Virus in an In Vitro Experiment.

We compared changes in the expression of the cytokine profile modified by SARS-CoV-2 and influenza virus in an in vitro experiment. A mixed population of immunocytes (T-helpers, B cells, NK cells, cytotoxic T lymphocytes, and monocytes) was isolated from peripheral venous blood samples (n = 32) of conditionally healthy male donors aged 25-35 years. The modifying factors were recombinant adenovirus particles of 26 and 5 serotypes containing the gene encoding S protein of SARS-CoV-2, as well as vaccine antigens (hemagglutinins) of influenza virus type A (H1N1 and H2N3) and type B.

Optimization of L-PBF Process Parameters for Defect Reduction and Mechanical Strength of Ni-Cr-Mo-Nb Superalloy Using Multi-Objective Methods.

In the context of Additive Manufacturing (AM), particularly the Laser Powder Bed Fusion (L-PBF) technique, optimizing process parameters is essential for achieving dense, defect-free materials. This study investigates the optimization of L-PBF process parameters for a Ni-Cr-Mo-Nb-based superalloy using an integrated three-stage methodology. Stage A applies Grey Relational Analysis to identify the most favourable parameter sets.

Thin Films of Tungsten Disulfide Grown by Sulfurization of Sputtered Metal for Ultra-Low Detection of Nitrogen Dioxide Gas.

Tungsten disulfide (WS) is attractive for the development of chemiresistive sensors due to its favorable band gap, as well as its mechanical strength and chemical stability. In this work, we elaborate a procedure for the synthesis of thin films consisting of vertically and/or horizontally oriented WS nanoparticles by sulfurizing nanometer-thick tungsten layers deposited on oxidized silicon substrates using magnetron sputtering. According to X-ray photoelectron spectroscopy and Raman scattering data, WS films grown in an H-containing atmosphere at 1000 °C are almost free of tungsten oxide.

L-Cysteine/Silver Nitrate/Iodate Anions System: Peculiarities of Supramolecular Gel Formation with and Without Visible-Light Exposure.

In this study, novel anion photo-responsive supramolecular hydrogels based on cysteine-silver sol (CSS) and iodate anions (IO) were prepared. The peculiarities of the self-assembly process of gel formation in the dark and under visible-light exposure were studied using a complex of modern physico-chemical methods of analysis, including viscosimetry, UV spectroscopy, dynamic light scattering, electrophoretic light scattering, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. In the dark phase, the formation of weak snot-like gels takes place in a quite narrow IO ion concentration range.
