Squalene-based adjuvant compositions that can provide effective induction of specific humoral immune response have been developed. Recombinant receptor-binding domain (RBD) of surface S-protein of SARS-CoV-2 was used to evaluate the properties of the composition. Immunization of mice with the developed squalene-based compositions in combination with RBD allows obtaining high titers of specific antibodies: from 10 to 2×10.

Within this work, structure-property relationships of oxy-QPSs were estimated by systematic analysis of physical-chemical properties. The influence of the oxygen-containing substituent was examined by comparing the properties of oxy-QPSs in homology series as well as with phosphonium analog-included alkyl side chains.

Four geosites represent sections of Givetian-Famennian (Middle-Late Devonian) deposits formed in the tectonically active zone where small terranes accreted with the Siberian continent. There, carbonate deposition in tropical conditions prevailed and rich ecosystems evolved.

The ω-bromoacyl ferrocenes were subsequently introduced to quaternization reaction with tri--butyl phosphine, which resulted in phosphonium salts.

Little academic research has however examined the scope and the scale of these changes, especially in the context of foodservice provision. This mixed methods study explores the effect of Covid-19 on food consumption in English households at home and away.
