Circular dichroism spectropolarimetry and X-ray scattering data, obtained using synchrotron radiation, can yield information about the secondary and tertiary structure of proteins in solution. These techniques have been used to analyse the architecture and shape of a complex of two proteins in solution. The crystal structures of two separate proteins, the… (More)
Previous work has shown that organosilica-based xerogels have the potential to control biofouling. In this study, modifications of chemistry were investigated with respect to their resistance to marine slimes and to settlement of barnacle cyprids. Adhesion force measurements of bovine serum albumin (BSA)-coated atomic force microscopy (AFM) tips to xerogel… (More)
Four-component xerogel films consisting of 1 mole-% n-octadecyltrimethoxysilane (C18) and 50 mole-% tetraethoxysilane (TEOS) in combination with 1-24 mole-% tridecafluoro-1,1,2,2-tetrahydrooctyltriethoxysilane (TDF) and 25-48 mole-% n-octyltriethoxysilane (C8) and a 1:49:50 mole-% C18/TDF/TEOS were prepared. Settlement of barnacle cyprids and removal of… (More)
Forty-one species of mollusks from 12 families and 18 genera were revealed in 21 water bodies of Volgograd oblast. Data on the species composition, dominant complex, and ecological peculiarities of mollusks are presented.
Novel derivatives of α-truxillic acid with a camphor framework were synthesized and evaluated for their in vivo analgesic activity. α-Truxillic acid derivatives were prepared via solvent-free photocatalyzed [2+2] cyclodimerization of (E)-cinnamic acid. Target compounds were obtained through the substitution of –Cl or –OH groups in α-truxillic acid. The… (More)
The synthesis of symmetric dimeric camphor derivatives containing two quaternary nitrogen atoms was performed and their myorelaxant activity in mice was evaluated. For the comparison, some salts derived from meta- and para-xylylene dibromides were synthesized and their activity was tested.
