Abstract: The present invention provides methods for making polysaccharide-protein conjugates in which polysaccharides, typically from bacteria, are conjugated to a carrier protein by reductive amination under conditions which improve conjugation reaction consistency, increase consumption of protein during conjugation reaction, generate conjugates of higher molecular weight, and/or reduce the levels of free cyanide in the conjugate reaction product. The polysaccharide-protein conjugates obtained using these methods are useful for inclusion in multivalent vaccines.

Abstract: The invention provides a method for producing an orexin neuron by culturing a pluripotent stem cell or a neural progenitor cell in the presence of N-acetyl-D-mannosamine and optionally in the presence of at least one inhibitor selected from the group consisting of a Sirtuin 1 inhibitor and an O-linked ?-N-acetylglucosamine transferase inhibitor. The invention also provides a therapeutic agent for narcolepsy or eating disorders, such as anorexia, containing N-acetyl-D-mannosamine, which is based on the induction of orexin neuron in vivo.

Abstract: The present invention is directed to a composition of matter, in particular a food composition, dietary or food supplementation, and pharmaceutical composition, respectively. The composition of matter reduces the risk of neuropathy, neurodegenerative diseases including late-onset Alzheimer's disease, and cancer, in particular of pancreatic, esophageal, oropharyngolaryngeal, liver, colorectal, lung and/or breast cancer, in particular the drug and/or alcohol induced risk of said diseases. In this respect, the present invention is also directed to a composition of matter; in particular a food composition, dietary or food supplementation, and pharmaceutical composition, respectively, which supports and/or moderates the alcohol degradation process within the human body.
