[Spatial Models of Piezo Proteins and Protein-Protein Interaction Networks in Trichoplax Animals (Placozoa)].

The marine free-living organism Trichoplax (phylum Placozoa) resembles a unicellular amoeba in shape and type of movement. Trichoplax diverged from the main evolutionary tree in the Neoproterozoic Era. Trichoplax provides one of the simplest models of multicellular animals and a strong example of how cells of an organism interact to form an ensemble during its development and movement.

[Spatial Reconstruction of TRPC Mechanoreceptors of the Ctenophore Mnemiopsis leidyi A. Agassiz, 1865].

The ctenophore Mnemiopsis leidyi A. Agassiz, 1865 responds to gentle mechanical stimulus with intense luminescence; however, the mechanism of this phenomenon is unknown. We searched for possible mechanosensitive receptors that initiate signal transduction resulting in photoprotein luminescence.

Long-Term Antimicrobial Performance of Textiles Coated with ZnO and TiO Nanoparticles in a Tropical Climate.

This paper reports the results of the large-scale field testing of composite materials with antibacterial properties in a tropical climate. The composite materials, based on a cotton fabric with a coating of metal oxide nanoparticles (TiO2 and/or ZnO), were produced using high-power ultrasonic treatment. The antibacterial properties of the materials were studied in laboratory tests on solid and liquid nutrient media using bacteria of different taxonomic groups (Escherichia coli, Chromobacterium violaceum, Pseudomonas chlororaphis).

On the orientation of the chains in the mercerized cellulose.

The cold alkaline treatment or mercerization of cellulose is widely used in industry to enrich the cellulose raw with high-molecular-weight [Formula: see text]-cellulose. Washing out of hemicelluloses by alkalies is accompanied by the rearrangement of the cellulose chains' packing, well known as a transition between cellulose I and cellulose II. Cellulose II can also be produced by the precipitation of the cellulose solutions (regeneration).

Structure and properties of helical fibers spun from cellulose solutions in [B]Cl.

Man-made fibers were spun from solutions of cotton and wood cellulose in ionic liquid (1-butyl-3-methyl-imidazolium chloride, [B]Cl). Depending on the concentration, cellulose dissolved in [B]Cl down to macromolecules or nanofibrils. The artificial fibers had a diameter of about 100 nm, were uniform, transparent, helical, and optically active.
