Dr Stuart Chalk – new Advisory Board member for Analytical Abstracts

28 May 2014

Analytical Abstracts would like to welcome a new Advisory Board member to the Board: Dr Stuart Chalk.

Stuart Chalk

Dr. Stuart J. Chalk is an Associate Professor in the Department of Chemistry. Dr. Chalk’s research emphasis is in the areas of environmental monitoring, XML tools for Chemical Informatics, linked chemical data, and the semantic web. Dr. Chalk joined UNF in 1996. Since then he has received an Undergraduate Teaching Award, published the first two UNF patents, and was co-PI on an NSF funded grant for the Analytical Sciences Digital Library (http://www.asdlib.org), a digital library for the enhancement of analytical science education. In 1997 he created the Flow Analysis Database, an online resource for searching the flow analysis literature (http://www.fia.unf.edu/).

Currently, Dr. Chalk is working on colorimetric methods of analysis for the determination of cyanide, nitrate/nitrite and phosphate/arsenate. He is the software and metadata architect of an open source electronic laboratory notebook called the Eureka Research Workbench and designer of the Experiment Markup Language (ExptML), a markup language created to capture and store research data from scientific experiments (http://exptml.sourceforge.net). Dr. Chalk is also one of the authors of the Lower St. Johns River Report (http://www.sjrreport.com), a City of Jacksonville Environmental Protect Board grant, and is the curator/developer of the UNF Environmental Center’ Digital Archive project.

Stuart joins the rest of the Advisory Board in the oversight of the Royal Society of Chemistry’s premier current awareness and information retrieval service for analytical scientists.

Rapid blood test for critically ill newborns

Test for methylarginines in newborn infants

Developing an analytical technique for use in the field of neo-natal intensive care presents a significant challenge to researchers. Newborn infants who are very premature and unwell can’t safely provide large blood samples for analysis, and a fast turn-around of lab results is crucial for a life-saving diagnosis.

Methylarginines (MAs) are nitric oxide synthase inhibitors which have been linked to respiratory problems in newborns. Researchers led by Susan Lunte at the University of Kansas, USA, report the use of capillary electrophoresis (CE) to measure and track methylarginine concentrations in infant blood plasma for the first time. Their newly developed sample preparation and separation methods are specifically designed to cope with low volume plasma samples, and the results confirm that infants in neo-natal intensive care units (NICUs) have extremely high MA levels.
