This report used high-performance affinity microcolumns to examine the changes in binding by sulfonylurea drugs to in vivo glycated HSA that had been isolated from individual patients with diabetes. An immunoextraction approach was developed to isolate HSA and glycated HSA from clinical samples, using only 20 μL of plasma or serum and 6–12 nmol of protein to prepare each affinity microcolumn. It was found that the affinity microcolumns could be used in either frontal analysis or zonal elution studies, which typically required only 4–8 min per run. The microcolumns had good stability and allowed data to be obtained for multiple …


Biomarkers Of Disease : Concentrations In The Serum Of Women During Natural And Stimulated Ovarian Cycles And During Early Pregnancy, Melissa Stemp Jan 2013

Biomarkers Of Disease : Concentrations In The Serum Of Women During Natural And Stimulated Ovarian Cycles And During Early Pregnancy, Melissa Stemp

Theses: Doctorates and Masters

Molecular biomarkers are chemical signatures that all cell types possess. They are used in medicine to evaluate both normal biological events and pathogenic processes. A series of biomarkers associated with cancer of the breast, ovaries and other parts of the female reproductive tract and the monitoring of pregnancy were measured in disease‐free women. The biomarkers measured were prostate specific antigen (PSA), CA125, CA15‐3, CA72‐4, and pregnancy associated plasma protein‐a (PAPP‐A). The patterns of change during natural and stimulated ovarian cycles and early pregnancy were investigated to determine if these biomarkers could reflect normal events relating to ovulation and implantation/placentation. In …
