Hedwig Conrad-Martius a développé, dans les années 1930, une conception en grande partie originale du jugement existentiel, dans la perspective d’une ontologie d’allure aristotélicienne. L’idée à la base de cette conception est que l’être existentiel et l’être copule sont unis par une relation d’analogie, et que celle-ci doit servir de principe directeur pour la clarification des « sens de l’être ». Cette idée a conduit Conrad-Martius à élaborer une théorie assez sophistiquée de l’« être immanent à l‘état de choses », ainsi qu’une conception réaliste suivant laquelle le prédicat existentiel exprime une propriété de premier degré, qui doit être mise au jour par l’intuition des essences. On s’attachera non seulement à détailler son analyse du jugement existentiel, en remontant à ses sources chez Reinach, Pfänder et, indirectement, chez Meinong, mais aussi à en clarifier quelques implications métaphysiques.

The cytokines interleukin (IL)-1b and tumor necrosis factor (TNF)-a induce b-cell death in type 1 diabetes via NF-kB activation. IL-1b induces a more marked NF-kB activation than TNF-a, with higher expression of genes involved in b-cell dysfunction and death. We show here a differential usage of the IKK complex by IL-1b and TNF-a in b-cells. While TNF-a uses IKK complexes containing both IKKa and IKKb, IL-1b induces complexes with IKKa only; this effect is achieved by induction of IKKb degradation via the proteasome. Both IKKg and activation of the TRAF6-TAK1-JNK pathway are involved in IL-1b-induced IKKb degradation. [less ▲]

Macadamia nuts are among the most nutritious and highest in monounsaturated oil content among edible nuts1. They are widely grown in Australia (46 % of total production), United States of America, especially in Hawaii, South Africa and Guatemala2. In practice, there are several steps involved in macadamia processing, including sorting and grading, drying, cracking, roasting, packaging and storage. Drying is a very crucial step as it needs to preserve macadamia quality as well as enhance storage stability through the reduction of water activity. It is obvious that physical properties of the nut contribute to its drying characteristics, and hence its storage stability. Accurate measures such as kernel volume ratio or shell density could help for improving drying efficiency. We present a methodology to investigate structural differences between varieties of macadamia nuts in order to understand the factors involved in storage stability. Fresh nuts-in-shell are scanned by X-ray microtomography, and the different parts of the nuts (shell, kernel, tracheids) are segmented by a set of classical 3D image operators. After image segmentation, volumes are determined, and additional weighing of the nuts allows density measurements. These quantities are plotted for several nuts from each variety. [less ▲]

Since its first implementation in 1997, MALDI Mass Spectrometry Imaging (MALDI MSI) has become an important tool in the proteomic arsenal, especially for biomarker hunting. First dedicated to high molecular weight, MALDI MSI is more and more used to map the distribution of small molecules too (lipids, drugs and metabolites,…). Last developments tend to improve the sample treatments to obtain the best spatial resolution as possible. From this perspective, great efforts have been made on the MALDI matrix deposition methods. Now, one of the remaining challenges for MALDI-MSI users consists of identification of detected molecules. For high molecular weight, methods inspired by classical proteomics techniques, are regularly used. Bottom-Up (PMF obtained after in situ trypsin digestion) and Top-Down (in situ In-Source Decay) approaches have been used directly from a tissue slice, leading to the identification of some of the most abundant proteins present at the surface of the tissue. When small molecules are analyzed, the identification is more straightforward. Indeed, tandem mass spectrometry can easily be used, leading to the fragmentation of the detected compounds which allows their unambiguous identification. This identification is even more reliable when high resolution exact mass measurements can be performed. In this talk, I will present how in our lab, we profit of the exceptional features of FT-ICR mass spectrometry for imaging and especially for identification purposes. The first example will deal with the benefit of high mass accuracy and high mass resolution for ISD-based protein identification. The mass accuracy and high mass resolution coupled with the use of a “cleaning” software allow unequivocal assignment of ISD fragments of proteins, in the low mass range (m/z between 300 and 900), whether from pure solutions or from tissue slices. The next examples will deal with the imaging of small molecules. The identification of drugs and their metabolites is facilitated with high mass accuracy. In our lab, we work on the localization of methadone and its first metabolite, EDDP in necrophagous fly larvae. In the mass range of these compounds (278-310 m/z), many matrix ion peaks are detected and the unique features of FT-ICR allows for unambiguous identification thanks to exact mass measurements. We also use MALDI Imaging to map the messenger molecules between plant roots and beneficial bacteria. The comparison of spectra recorded with a TOF/TOF instrument and with a FT-ICR demonstrates that high resolution allows for detecting molecules which could have been missed otherwise. It also allows to distinguish unknown compounds from alkali adducts of known molecules. [less ▲]
