Aberrant protein glycosylation has been recognized to be associated with many neurodegenerative disorders, including Alzheimer and Parkinson disease. Using mass spectrometry-based technologies to catalog and quantify glycoproteins in these diseases is expected to provide insight into not only the biochemical

We reported a novel hydrogelator with L-lysine as a linker to connect 7-carboxyl methoxycoumarin and hydrazine as lipophilic and water-soluble moieties. Ultrasound accelerated the gelation and induced homogenous self-assembly of fibrils into entangled 3D networks. The hydrogel exhibits great potential

Extracellular glycoproteins frequently carry terminal sialic acids on their N-linked and/or O-linked glycan structures. In this chapter a sialic acid specific capture-and-release protocol for the enrichment of N- and O-glycopeptides originating from glycoproteins in complex biological samples is described. The

A series of new monoazo disperse dyes containing pyrazolopyrimidine moieties was synthesized by coupling malononitrile or 3-aminocrotononitrile with 4-hydroxy- benzenediazonium chloride. Treatment of the resulting products with hydrazine hydrate yields the corresponding 4-arylazoaminopyrazoles, which then react with either 2,4-pentanedione and

An integrated microfluidic/magnetophoretic methodology was developed for improving signal response time and detection limits for the chronoamperometric observation of discrete nanoparticle/electrode interactions by electrocatalytic amplification. The strategy relied on Pt-decorated iron oxide nanoparticles which exhibit both superparamagnetism and electrocatalytic activity
