1. Glycosylation in cancer and infection : the role of sialic acid
Abstract : Sialic acids (SA), a group of nine-carbon backbone monosaccharides are abundantly expressed in vertebrates. They are usually linked to the terminal of glycan chains and play crucial roles in many biological processes, including cell adhesion, cell-cell interactions, immune modulation, cancer cell migration and invasion, as well as viral infections.

2. Design and Synthesis of Sialic Acid Conjugates as Inhibitors of EKC-causing Adenoviruses
Abstract : The combat against viral diseases has been, and still is, a major challenge in the field of drug development. Viruses are intracellular parasites that use the host cell ma-chinery for their replication and release. Therefore it is difficult to target and destroy the viral particle without disturbing the essential functions of the host cell. READ MORE

3. Moleculary imprinted micro- and nanoparticles for cancer associated glycan motifs
Abstract : Sialic acids are an important family of monosaccharides that are typically found as terminal moieties of glycans. Aberrant sialylation has been proven to correlate with various diseases including cancer. Glycosylation analysis is complex due to high diversityof the glycan isomers and their low abundance.

4. Synthesis of Conformationally Restricted Oligosaccharides
Abstract : Gangliosides are sialic acid-containing glycosphingolipids that often are present in increased amounts on tumor cells. Since the gangliosides are hydroxy-acids, they can form lactones. The lactones have been suspected to be more immunogenic than the open forms, but are in practise poor immunogens due to their ease of hydrolysis. READ MORE

5. Adenovirus-host interactions : implications for tropism and therapy
Abstract : Human adenoviruses (HAdVs) are common viruses often associated withgastrointestinal, ocular and respiratory infections. They can infect a widevariety of cells, both dividing and non-dividing. HAdVs attach to and infecttarget cells through interactions with cellular receptors. READ MORE
