Stable isotope tracers site

 

This is the website of the Special Interest Group (SIG) in Tracer Methodology in Metabolism that is part of the European Society of Clinical Nutrition and Metabolism (www.espen.org).

 

Our mission is to promote the use of high quality tracer methods in clinical metabolism research in Europe.

 

We do this by organising a Tracer Methodology Discussion Group that meets annually in conjunction with the annual ESPEN meetings and openly discusses tracer methods with all their strenght and assumptions. We had 11 of these meetings over the years. We also organise a Tracer Methodology Course. The course is an intensive introductory course which is meant for everyone interested in tracer methodology for metabolic research and wants to learn all the details in order to be able to use it in their own research.

 

Tracer Methodology Course.The next course is planned for the winter months (january or February) 2013 in southern France most likely in Nice. Please mail me if you want to receive updates on this course.

 

Tracer Methodology Discussion Group. This year we will have the discussion group in conjunction withg the annaula ESPEN meeting in Gothenburgh, Sweden. See ESPEN website for details.

 

Last year the discussion group meeting was held in Nice on sunday September 5th. Dwight Matthews from the University of Vermont, Burlington, USA discussed the use of APE versus tracer/tracee ratio in your tracer calculations. Dwight Matthews has been doing tracers for a few decenia and claims to do stable isotopes better (www.uvm.edu/~dmatthew/). Dwight explianed about the tracers and their calculations when used in metabolic research and finally came to the conclusion that when using whole body tarecr kinetics measured during continuous infusion of the tracer you can use either APE of TTR BUT when using APE one should use a slightly deifferent formula that subtracts the amount of tracer infused. A report will be produced later with more details.
