Vancomycin was covalently bound, involving the primary amino group of the molecule through the hydroxypropyl radical to the C6 position of the anhydroglucose units of the dextran main chain. Covalent binding is necessary to prevent spontaneous release of the antibiotic from the gel, thereby reducing the risk of bacterial multiresistance.

PR-10 proteins are clinically relevant allergens that have the ability to bind hydrophobic ligands, which can significantly increase their allergenicity potential. It has been recently shown that not only the birch pollen allergen Bet v 1 but also the alder pollen allergen Aln g 1, might act as a true sensitizer of the immune system.
View Article and Find Full Text PDFA polysaccharide gel containing covalently bound amikacin, a broad-spectrum antibiotic, was produced by using epichlorohydrin-activated hydroxyethyl starch (HES). The structure of the polymers was analyzed by C and H nuclear magnetic resonance (C NMR and H NMR) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. The sites of covalent attachment of amikacin to the epoxypropyl substituent and the HES backbone were determined.

After 21 days of exposure to CS, plasma concentrations of cortisol, glucose, and Na increased, indicating stress. Total plasma osmolality (Osm ) and osmolality generated by inorganic (Osm ) and organic osmolytes (Osm ) also increased, the latter by ~2%.
