     U.S. Patent No. 7,125, 678, "Protein biopolymer markers predictive of
 type II diabetes," U.S. Patent No. 7, 097,989, "Complement C3 precursor
 biomarker predictive of type II diabetes," and U.S. Patent No. 7,094,549,
 "Fibronectin biopolymer marker indicative of insulin resistance," relate to
 the use of mass spectrometry and time-of-flight detection to identify
 biopolymers that characterize type II diabetes. These markers could
 potentially be used in applications of disease risk assessment and
 development of therapeutic avenues.
     In addition, U.S. Patent No. 7,101,680 "Method for detecting the
 presence of monomeric brain associated human glutamine synthetase," relates
 to a method for detecting a biochemical marker, human glutamine synthetase,
 by immunoassay as a potential diagnostic for Alzheimer's disease. In
