Multivariate Solutions to Metabonomic Profiling and Functional Genomics, Part 1 PDF Print E-mail
Written by Henrik Antti, Elaine Holmes, Jeremy Nicholson, Imperial College, London   
Metabonomics, defined as a systems approach to investigating the metabolic consequences of (patho)physiological or genetic modification in a multivariate and dynamic manner, has evolved from the work of Nicholson and co-workers using high field NMR spectroscopic analysis of biological matrices as the dominant analytical platform.
A link (pdf) will be added during September 2006 to the full tutorial

Metabonomics forms part of a suite of platform technologies, which together provide a holistic picture of an organism in terms of basal state and/or response to pathophysiological or genetic stimuli. Whilst genomics allows the measurements of responses of living systems to drugs at the genetic level and proteomics enables the response of an organism at the level of cellular proteins to be assessed, neither technology provides a complete description of a toxicological episode. In order to understand fully the pathophysiological processes induced by xenobiotics, the metabolic status of the whole organism needs to be taken into account.

Can we use the regression coefficient profile for selecting PLS components?
The linear model y=Xb + f is often used in chemometrics. Unfortunately, we have put too much emphasis on the importance of the regression coefficient profile b, and mistakenly assumed or believed that it should be a good estimate of the "pure profile". This is not true, and I will argue why in later editorials. But this time, I want to address an earlier question that was posed in relation to the regression coefficient profile.

Statistical Molecular Design, part 5
We have in the four previous tutorials reviewed the concept of statistical molecular design (SMD) and shown some illustrations of where and when this technology may be used, see previous tutorials [1 - 4]. The objective of this fifth editorial is to consider ways to extend the basic SMD-approach, so that also more demanding problems may be addressed. In so doing, we will also come across some of the latest developments in this field.
