The purpose of this study were to examine if the mRNA of the peripheral dopamine receptor is changed in schizophrenia patients. 50 Naive patients were enrolled. After extracting RNA from white blood cells, cDNA is synthesized. After doing the quantitative Real-time PCR, expression of D3 receptors in healthy persons and patients were compared. Results of this examinations reveals that expression of D3 receptor is increased in compared with controls sample.

This presentation describes the potential of using a new fully automated QCM biosensor and a commercial SPR biosensor for the detection of PSA, a biomarker for prostate cancer. Initially a new buffer was formulated to eliminate 98% of the non-specific human serum protein binding to the sensors. Obtained results indicate that both instruments can be used for the fast and easy detection of PSA (0.29-150 ng/ml) in serum.

Using cross validation, permutation and rank products statistical procedures we identified biomarker regions in proton spectra of polar metabolites extracted from the algae Chlamydomonas reinhardtii (light and dark grown) and from the yeast Saccharomyces cerevisae (aerobically and anaerobically grown).

Collection of pancreatic fine needle aspirates (FNAs) in RNARetain™ allows stabilization and protection of RNA in tissues containing high levels of nucleases; Differential miRNA expression in pancreatic FNAs accurately classifies benign and malignant tissue; Combinations of miRNA and mRNA expression signatures improve the separation between normal tissue and chronic pancreatitis; microRNAs are suitable analytes for molecular characterization of fine needle aspirates from pancreatic tissues.

Combination of the comprehensive metabolic profiling utilizing three complementary analytical methods for MS data acquisition and Genetic Algorithms technique for feature selection presenting intriguing avenue for finding and exploration small subsets of strong classifiers.

Poster shows the advantages of a ligand-based depletion method that is highly specific, disposable, cost effective, and flexible. Pall’s Enchant Multi-Protein Affinity Separation Kit is a strong addition to the product choices for scientists engaged in biomarker discovery and proteomics research.

Poster data assesses use of Pall’s Accuwik Ultra membrane as a reliable tool for direct collection of clinical samples including saliva and plasma, enables stability during sample storage, and allows for rapid and efficient release of clinically relevant protein biomarkers suitable for diagnostic analyses.

Poster data highlights the advantages of a ligand-based depletion method that functions in the presence of urea and is highly specific, disposable, cost effective, and flexible.

Current presentation is dedicated to case studies and illustrates diversity of the projects. Cases representing different projects combine the same analytical platform we utilize for metabolomics study of blood plasma and urine. While pattern recognition presents certain challenges but rather ones that can be resolved, identification of low abundant unknown biomarkers is critical for the field and offers significant technical challenge in spite of considerable progress in modern analytical techn
