Abstract:
A series of eight n-octyl (thio)glycosides (1α, β–4α, β) with d-glucose or d-galactose-configured head groups and varying anomeric configuration were synthesized and evaluated for glass transition behaviour, membrane permeability, and ice recrystallization inhibition (IRI) activity. Of these, n-octyl β-d-glucopyranoside (2β) exhibited a high glass transition temperatures (Tg), both as a neat sample and 20 wt-% aqueous solution. Membrane permeability studies of this compound revealed cellular uptake to concentrations relevant to the inhibition of intracellular ice formation, thus presenting a promising lead candidate for further biophysical and cryopreservation studies. Compounds were also evaluated as ice recrystallization inhibitors; however, no detectable activity was observed for the newly tested compounds.

Abstract:
Ice-binding proteins (IBPs) are found in many biological kingdoms where they protect organisms from freezing damage as antifreeze agents or inhibitors of ice recrystallization. Here, the crystal structure of recombinant IBP from carrot (Daucus carota) has been solved to a resolution of 2.3 Å. As predicted, the protein is a structural homologue of a plant polygalacturonase-inhibiting protein forming a curved solenoid structure with a leucine-rich repeat motif. Unexpectedly, close examination of its surface did not reveal any large regions of flat, regularly spaced hydrophobic residues that characterize the ice-binding sites (IBSs) of potent antifreeze proteins from freeze-resistant fish and insects. An IBS was defined by site-directed mutagenesis of residues on the convex surface of the carrot solenoid. This imperfect site is reminiscent of the irregular IBS of grass ‘antifreeze’ protein. Like the grass protein, the carrot IBP has weak freezing point depression activity but is extremely active at nanomolar concentrations in inhibiting ice recrystallization. Ice crystals formed in the presence of both plant proteins grow slowly and evenly in all directions. We suggest that this slow, controlled ice growth is desirable for freeze tolerance. The fact that two plant IBPs have evolved very different protein structures to affect ice in a similar manner suggests this pattern of weak freezing point depression and strong ice recrystallization inhibition helps their host to tolerate freezing rather than to resist it.

Abstract:
Gas hydrates have been and still remain a difficult problem in the oil and gas industry, solution of which requires considerable efforts and resources. In this work, the mechanism of phase transformations at negative temperatures in the formation of the solid phase is preliminarily studied using the reservoir system models consisting of a gas mixture and a solution of gas hydrate formation inhibitor of thermodynamic action with high concentration in distilled water. A system of three-dimensional lighting and image magnification is used to visually detect phase boundaries by creating optical effects. Thus, in the system “inhibitor solution – gas hydrate – gas” in the process of gas hydrate recrystallization in the conditions close to equilibrium, microzones of supercooled water may occur, which in the absence of gas molecules access is crystallized into ice. The result of such solid phase structure formation is its increased stability in nonequilibrium conditions for a relatively long period of time.

Abstract:
Summary Antifreeze proteins (AFPs) present in plants may inhibit ice recrystallization even at low concentrations, and show potential application to many frozen foods. This study evaluated the presence of antifreeze proteins in naturally cold acclimated and non-acclimated leaves of Drimys angustifolia, Senecio icoglossus and Eucalyptus ssp. No proteins were detected in apoplastic extracts of Eucalyptus ssp. Extracts of cold acclimated and non-acclimated S. icoglossus showed protein concentrations of 42.89 and 17.76 µg mL-1, both with bands between 25 and 37 kDa in the SDS-PAGE. However, they did not inhibit recrystallization. The extract of cold acclimated D. angustifolia contained a protein concentration of 95.17 µg mL-1, almost five times higher than the extract of non-acclimated D. angustifolia. In the extract of cold acclimated D. angustifolia, there was presence of ice recrystallization inhibitors. This extract showed a protein band just below 37 kDa and another more intense band between 20 and 25 kDa. It is the first time that the presence of antifreeze proteins in this species is being described.

Full text
Abstract:
Background: When developing low-temperature cell storage methods, a serious problem is recrystallization, which leads to cell damage during thawing. Previous studies have shown the promising use of polyvinyl alcohol (PVA) as an inhibitor of recrystallization. But the mechanisms of protective action of PVA are not finally clarified. So, it is not known what structural features contribute to implementation of PVA antirecrystallization properties in the cryoprotective concentration range. Objectives: Establishing the peculiarities of structuring PVA molecules in aqueous solutions using the fluorescent probe. Materials and Methods: Aqueous solutions of 0.1–5% (wt.%) PVA with molecular mass (m.m.) of 9 and 31 kDa) were studied. Fluorescence probe method, photometry, stalagmometry, and molecular modeling were used. Results: Using the 3-hydroxy-4¢-(N,N-dimethylamino)flavones (FME) fluorescent probe it was found that in 0.1–5% of PVA (m.m. 9 and 31 kDa) aqueous solutions the structural organization of polymers changes with formation of different in size and structure of local hydrophobic regions. In PVA solutions, m.m. 9 kDa micelles with smaller cavities are formed in which FME is densely surrounded by polymer segments. In the case of PVA m.m. 31 kDa, it forms micelles with smaller cavities surrounded by polymer segments. PVA m.m. 31 kDa forms micelles with larger in size and more hydrophilic cavities. If the content is more than 3%, PVA m.m. 31 kDa aggregates are partially destroyed, which may be the result of increased water content. Under these conditions, PVA m.m. 9 kDa micelles are enlarged. as a result of aggregation. According to molecular modeling data, PVA is able to form strong hydrogen-linked complexes with the surface of ice nanocrystals. Such complex, having a hydrophobic surface, can depolarize water molecules, thus slowing down further growth of ice crystals. Conclusions: Changes in the structural organization, which may affect the recrystallization properties, have been found in water solutions of PVA. The mechanism of implementation of polymer anticrystallization activity has been suggested. The possible role of structure and supramolecular organization of PVA in aqueous solutions in understanding the mechanisms of depressing recrystallization during freeze-thawing of cells is discussed.
