Impedimetric Characterization of NanA Structural Domains Activity on Sialoside-Containing Interfaces.

is a pathogenic bacterium that contains the surface-bound neuraminidase, . has two domains that interact with sialosides. It is hard to determine the contribution of each domain separately on catalysis or binding.

Pectin Remodeling and Involvement of AtPME3 in the Parasitic Plant-Plant Interaction, -.

is a root parasitic plant fully dependent on host plants for nutrition and development. Upon germination, the parasitic seedling develops inside the infected roots a specific organ, the haustorium, thanks to the cell wall-degrading enzymes of haustorial intrusive cells, and induces modifications in the host's cell walls. The model plant is susceptible to ; thus, mutants in cell wall metabolism, particularly those involved in pectin remodeling, like , are of interest in studying the involvement of cell wall-degrading enzymes in the establishment of plant-plant interactions.

Multivalent inhibition of the fumigatus KDNase.

is a saprophytic fungus and opportunistic pathogen often causing fatal infections in immunocompromised patients. Recently KDNAse, an exoglycosidase hydrolyzing 3-deoxy-D-galacto-D--nonulosonic acid (KDN), a rare sugar from the sialic acid family, was identified and characterized. The principal function of KDNAse is still unclear, but a study suggests a critical role in fungal cell wall morphology and virulence.

Early Detection of Cardiotoxicity Using [Cu]Cu-NODAGA-E[(cRGDyK)]2 PET Imaging in a Rat Model of Doxorubicin-Induced Heart Failure.

Doxorubicin (DOX) is a common and highly effective chemotherapeutic. However, its use is limited by cardiotoxic effects and the lack of methods to detect these at early time points. In the present study, we evaluated if [Cu]Cu-NODAGA-E[(cRGDyK)]2 positron emission tomography-computed tomography ([Cu]Cu-RGD PET/CT) could detect cardiotoxicity in a rat model of DOX-induced heart failure.
