Analysis of urinary pseudouridine by micellar electrokinetic capillary chromatography

Tailor-Made Molecularly Imprinted Polymer for Selective Recognition of the Urinary Tumor Marker Pseudouridine

Pseudouridine (Ψ) is an important urinary cancer biomarker, especially in human colorectal cancer (CRC). Disclosed herein is the first Ψ molecularly imprinted polymer (Ψ-MIP) material obtained from tailor-engineered functional monomers. The resulting MIP imprint exhibits a remarkable imprinting factor greater than 70. It is successfully used for the selective recognition of Ψ in spiked human urine. This selective functionalized material opens the route to the development of inexpensive disposable chemosensors for noninvasive CRC diagnosis and prognosis.

Capillary electrophoresis in clinical and forensic analysis: recent advances and breakthrough to routine applications

This paper is a comprehensive review article on capillary electrophoresis (CE) in clinical and forensic analysis. It is based upon the literature of 1997 and 1998, presents CE examples in major fields of application, and provides an overview of the key achievements encountered, including those associated with the analysis of drugs, serum proteins, hemoglobin variants, and nucleic acids. For CE in clinical and forensic analysis, the past two years witnessed a breakthrough to routine applications. As most coauthors of this review are associated with diagnostic or forensic laboratories now using CE on a routine basis, this review also contains data from routine applications in drug, protein, and DNA analysis. With the first-hand experience of providing analytical service under stringent quality control conditions, aspects of quality assurance, assay specifications for clinical and forensic CE and the pros and cons of this maturing, cost-and pollution-controlled age technology are also discussed.
