摘要:The present invention relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.

摘要:Compositions and methods for improving a child, such as an infant's health, are provided. The methods entail improving the quality of breast milk in a female human individual that provides breast milk, or expects to provide breast milk, to the child, by administering to the individual an agent that increases the individual's sensitivity to insulin, and/or an agent that reduces the substrate uptake, synthesis or secretion of long chain fatty acids, reduces the substrate uptake, synthesis or secretion of short chain fatty acids, increases the amino acid uptake, protein synthesis or protein secretion of proteins, or reduces the uptake or synthesis of lactose.
