Finally, a seventh scientific paper is published by the Poirrier-Falisse. After a huge batch of articles from Nandini, here is my second paper: Poirrier J.E., Guillonneau F., Renaut J., Sergeant K., Luxen A., Maquet P. and Leprince P.: " Proteomic changes in rat hippocampus and adrenals following short-term sleep deprivation" Proteome Science, 2008, 6(1):14 doi: 10.1186/1477-5956-6-14 Very briefly, in this study we show the influence of 4 hours of prolonged wakefulness in rats hippocampus and adrenals proteome. As usual, this paper is published in an Open Access journal. Here is my updated BibTeX file (and I also updated Nandini’s BibTeX file). ...

This week is very stressful because I am doing a 2200+ euros 2D-DIGE experiment (*) on samples from a rat organ we never studied before and from which I cannot obtain any more new samples. We found a new pattern of proteins dispersion (compared to our previous experiments on other organs) and, more importantly, we found a clear difference in protein expression in at least 2 spots. In the image below, all the whitish spots mean proteins in these spots are found in equal amounts in the 3 conditions. But spots in red or green mean proteins expressed at different levels (even on/off) between conditions! ...
