N-glycan analyses may serve uncovering disease-associated biomarkers, as well as for profiling distinctive changes supporting diagnosis of genetic disorders of glycan biosynthesis named congenital disorders of glycosylation (CDG). Strategies based on liquid chromatography (LC) preferentially coupled to electrospray ionization (ESI) - mass spectrometry (

The Neuroinflammatory Phenotype in a Mouse Model of Gulf War Illness is Unrelated to Brain Regional Levels of Acetylcholine as Measured by Quantitative HILIC-UPLC-MS/MS [PDF]
Many veterans of the 1991 Persian Gulf War (GW) returned with a chronic multisymptom illness that has been termed Gulf War Illness (GWI). Previous GWI studies have suggested that exposure to acetylcholinesterase inhibitors (AChEIs) in theater, such as sarin and/or pesticides, may have contributed to the symptomatology of GWI.

Comparative HILIC-UPLC analysis of immunoglobulin G N-glycome from saliva and plasma [PDF]
Immunoglobulin G (IgG) is the most abundant antibody in the blood and plays a critical role in host immune defence against infectious pathogens. IgG glycosylation is known to modulate IgG effector functions and is involved in the development and progression of disease.

Fine-Mapping of the Human Blood Plasma N-Glycome onto Its Proteome
Most human proteins are glycosylated. Attachment of complex oligosaccharides to the polypeptide part of these proteins is an integral part of their structure and function and plays a central role in many complex disorders.
