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 ▲]

La thèse analyse les politiques et les interventions en matière de protection de l'enfance au Burkina Faso. Les enseignements de cette recherche concernent sa dimension empirique d'une part et son objet spécifique d'autre part. Cet objet n'est pas le travail des enfants comme tel, mais la construction d'une politique publique dans un pays qui reste massivement rural et largement dépendant de l'aide internationale. [less ▲]

This paper highlights technical and economic choices for rural electrification in Africa and presents the rationale for trigeneration in health and education applications. An archetypal load profile for a rural health clinic (25 kWh/day 118-139 kWht ) is described and a regional analysis is performed for sub Saharan Africa by aggregating NASA meteorological data for e.g. insolation, temperature, and heating and cooling degree days using correlates to latitude. As a baseline for comparison, the technical, economic (using discounted cash flow) and environmental aspects of traditional electrification approaches, Photovoltaic (PV) systems and diesel generators, are quantified and options for meeting heating and cooling loads (e.g. gas-fired heaters, absorption chillers, or solar water heaters) are evaluated alongside an emerging micro-scale Concentrating Solar Power (CSP) technology featuring a solar thermal Organic Rankine Cycle (ORC). Photovoltaics hybridized with LPG/Propane and μ-CSP trigeneration are the lowest cost alternatives for satisfying important but often overlooked thermal requirements, with cost advantages for μ-CSP depending on latitudinal variation in insolation and thermal parameters. For a 15-year project lifetime the net present cost for meeting clinic energy needs varied from 44-55k USD, with specific levelized electricity costs of 0.26-0.31 USD/kWh. Diesel generation is both costly and polluting (94 tons CO2 per site over 15 years), while LPG/Propane based heating and cooling results in 160-400 tons CO2 emittted. The comparative analysis of available technologies implies that where the energy demand includes a mixture of electrical and thermal loads, as in typical health and education outposts, μ-CSP trigeneration approaches are cost effective and a non-carbon emitting.

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 ▲]
