The conformational behavior of the algal polysaccharide ulvan in aqueous solution has been studied. This biopolymer, containing limited regular regions of aldobiuronic sequences made of-D-glcpA-(1f4)-R-L-rhap 3-sulfate and of R-L-idopA(1f4)-R-L-rhap 3-sulfate, can be considered as a low-cost source of rare sugars with a potential impact on several(More)
The purpose of our study was to develop new delivery systems for drugs effective against breast cancer by using biodegradable and biocompatible capsules. Redox-active microcapsules based on thiolated polymethacrylic acid (PMA) were employed. The interaction of these PMA SH capsules with breast cancer cells and the mechanism of their internalization was(More)
Microbubbles (MBs) have specific acoustic properties that make them useful as contrast agents in ultrasound imaging. The use of the MBs in clinical practice led to the development of more sensitive imaging techniques both in cardiology and radiology. Protein-MBs are typically obtained by dispersing a gas phase in the protein solution and the protein(More)
