|Johann Stojko||DSA||Ion Mobility Mass Spectrometry (IMS) : A promising tool for biomolecules characterization. |
For years, Mass Spectrometry (MS) has become a powerful analytical tool to further identify, characterize and quantify biomolecules. Liquid Chromatography (LC) coupling of this high sensitive and resolutive technology brings it an efficient separative power, particularly adapted to complex proteoms studies. More recently, conformational features can also be investigated, according to Ion Mobility (IM) implementation on last generation spectrometers, tuned to maintain non covalent interactions while preserving native conditions. Interestingly, this additional separative dimension, based on ions conformation, potentialize proteomics and complexomics applications, given an alternative approach to assess conformational data, compatible with NMR, SAXS and crystallography. Here, we will focus on basic principles of Mass Spectrometry and Ion Mobility, before discussing on their applications in proteins field.
|Emilio Rojas||DEPE||Natal and breeding dispersal in White Storks (Ciconia ciconia) : how migration impacts individuals’ distribution. |
Some migratory species like the White Storks (Ciconia ciconia) have a great fidelity toward the area where they were born. That means that they are very likely to come back next to their hatching places to reproduce and lay. Nevertheless, the competition between individuals upon food, sexual partners and nesting places sometimes forces them to disperse. We will focus here on the impact of the migration’s direction on the dispersal of this species. We will also see how far do individuals disperse depending on different factors, and this with a twenty years dataset concerning individuals from all around the French territory.
|Cécile Bopp||DRS||The proton as a dosimetric and diagnostic tool. |
Charged particles, like protons or carbon ions, are used nowadays to treat some cancers. These particles enable the delivery of a highly accurate dose to the tumors while sparing the surrounding healthy tissues. In this context, a “new” imaging modality that uses protons is studied. The aim is to improve the accuracy of treatment plans. My work consists in exploring the potential of proton imaging : each proton carries different information about the materials, and all of it is not used yet…
Au plaisir de vous voir vendredi 24 !
