Abstract The thermal unfolding of lysozyme in aqueous solution has been analyzed by (nano) differential scanning fluorimetry (nanoDSF) and calorimetry (DSC). In addition, dynamic light scattering (DLS) acquired parallel to the DSF measurements, was used confirm that change hydrodynamic radius upon is rather small ( R H,f =1.75 nm folded state; H,u =1.91 unfolded state). NanoDSF measurements were evaluated characterize folding/unfolding transition within classical two‐state folding model....
Mucus is a dynamic biological hydrogel, composed primarily of the glycoprotein mucin, exhibits unique biophysical properties and forms barrier protecting cells against broad-spectrum viruses. Here, this work develops polyglycerol sulfate-based dendronized mucin-inspired copolymer (MICP-1) with ≈10% repeating units activated disulfide as cross-linking sites. Cryo-electron microscopy (Cryo-EM) analysis MICP-1 reveals an elongated single-chain fiber morphology. shows potential inhibitory...
We review activity on the usage of a biphase H2O/CO2 system in organic synthesis as reaction medium green chemistry. The formation self-neutralizing carbonic acid such eliminates problem salt disposal, typical for acid-catalyzed reactions with usual mineral and acids. A large variety different to be performed are discussed detail, including cyclization/cycloaddition, hydroformylation, hydrogenation, reduction, coupling, rearrangement, substitution, addition, halogenation, hydrolysis,...
Chitosan macromolecules with different molecular weights and degrees of acetylation were dissolved in carbonic acid solutions saturated carbon dioxide at high pressure adsorbed from such onto model mica substrate. Their conformation on the substrate was revealed by means atomic force microscopy. The results observations indicate that there are nanosized stable aggregates peculiar, regular, reproducible geometry, which formed solutions. appear as rather persistent rod-like structures consist...
HMGB1, a nuclear DNA-binding protein, can be secreted by activated immune cells or passively released from damaged cells. In such cases, HMGB1 functions as an alarmin that activates the system. Excessive inflammation may lead to pathogenesis, whereas this response dampened polyanion binding, which impedes further receptor recognition. Moreover, is known form liquid droplets in cellular environment - phase separation directly linked its proper function. While A-Box domain believed primarily...
New functional medical materials with antibacterial activity based on biocompatible bacterial cellulose (BC) and Ag nanoparticles (Ag NPs) were obtained. Bacterial films prepared by stationary liquid-phase cultivation of the Gluconacetobacter hansenii strain GH-1/2008 in Hestrin–Schramm medium glucose as a carbon source. To functionalize surface immobilize NPs deposited magnetron sputtering, BC treated low-pressure oxygen–nitrogen plasma. The composition structure nanomaterials studied using...
Mucus is a dynamic biological hydrogel, composed primarily of the glycoprotein mucin, exhibits unique biophysical properties and forms barrier protecting cells against broad spectrum viruses. Here we developed polyglycerol sulfate-based dendronized mucin-inspired copolymer (MICP-1) with ~10 % repeating units activated disulfide as cross-linking sites. Cryo-EM analysis MICP-1 reveals an elongated single-chain fiber morphology. shows potential inhibitory activity many viruses such HSV-1...
The new process for producing silicones, characterized by controllable ratio between linear and cyclic products based on chlorine-free reagents, is suggested.
Bacterial cellulose (BC) is a natural polymer that has number of unique properties determine the need to synthesize large amounts it and search ways increase productivity strains optimize nutritive media. It known choice producer for BC synthesis an impact on its final this production. Under static liquid phase cultivation conditions, all cellulose-producing bacteria form uniform film medium surface serves as scaffold cells immobilization, thus providing them with access air/liquid...
Показана возможность синтеза стереорегулярного цис-гексафенилциклогексасилоксангексаола в неорганической жидкой среде. Взаимодействие каркасного олигофенилникельнатрийсилоксана с угольной кислотой можно рассматривать как метод получения функциональных органосилоксановых
It was found out that block copolymers of polystyrene and poly(4-vinylpyridine) with comparable lengths blocks could be dissolved in a high-pressure reactor containing water phase saturated carbon dioxide under high pressure at room temperature. This rather effective dissolution occurs due to protonation P4VP nitrogen-containing groups together plasticization the polymer material by compressed dense CO2 being contained autoclave. The selected form monodispersed micelles well-defined...
The possibility to synthesize stereoregular tris-cis-tris-trans- dodeca[(phenyl)(hydroxy)]cyclododecasiloxane (tris-cis-tris-trans-[PhSi(O)OH]12) in an inorganic liquid medium – aqueous carbonic acid solution was shown. interaction of polyhedral phenylcoppersodiumsiloxane, {[(C6H5Si(O)O−]12(Cu2+)4(Na+)4}*(L)m (L = Bun OH, H2O), with can be considered as a new 'green' method obtain functional organosiloxane macrocycles. In contrast the known methods, no organic solvents were used during...
