Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) is an emerging tool for clinical research. MALDI MSI can be used to elucidate the relative abundance and spatial localization of peptides and proteins throughout a tissue section. For this, a matrix is applied on the tissue in either a spotted array or a homogenous coating. Acquisition of mass spectra is then carried out by performing a raster with a laser across the tissue section in a defined pattern. The spectra acquired from each position on the tissue section contain molecular weight and intensity information representative of the biomolecules at that position. One can plot the intensity of any measured ion as a function of individual pixel locations to generate m/z specific images. But, if protein desorption/ionization and subsequent MS analyses provides a measurement of molecular weight, no protein identification is performed. To achieve this, several methods have been developed. In this talk, I will first present the methods inspired by classical proteomics techniques that are regularly used to identify proteins. Bottom-up and top-down approaches have been used directly from a tissue slice, leading to the identification of some of the most abundant proteins present within the tissue slice. Then, I will present the new developments led in our lab for imaging and especially for in situ protein identification. The first example will deal with the exceptional features of FT-ICR mass spectrometry for in-source decay (ISD)-based protein identification. The benefit of mass accuracy and high mass resolution allow unequivocal assignment of ISD fragments of proteins, in the low mass range (m/z between 400 and 900), whether from pure solutions or from tissue slices. The next example is the use of a matrix “cleaning” software that reduce/remove matrix peaks thus facilitating ISD spectra analyses. Finally, proteins identification by localization and MALDI-ISD profile matching will also be a really simplistic and interesting method that will complement the immunohistological techniques commonly used to validate expression of known biomarkers within diseased tissues.

Postharvest fungal pathogens, mainly Botrytis cinerea, Penicillum expansum and Gloeosporium spp., annually cause 5-20% losses of fruit. Control measures against these diseases include chemical fungicide applications, but the development of resistant fungal explains the growing interest for biological control. Pichia anomala strain K was previously identified as an efficient antagonist of pathogens on apples. Indeed, the percentage of protection of P.anomala against B.cinerea reached from 90 to 100% on apple wounds according to the experimental conditions. Microbiological, biochemical and molecular approaches demonstrated the implication of exo-β-1,3-glucanases in the mechanism of action of P.anomala. However, study of these mechanisms could be improved by observations under natural infection conditions in order to take into account the tripartite interactions host/antagonist/pathogen. The proteomic tool allowed an overview of process implicated in the antagonism against B.cinerea in such conditions. One 50mm wound per apple were covered by a membrane and inoculated by a P.anomala suspension then by B.cinerea or not. Samples were collected during the exponential and stationary phase to identify the early and later responses to the presence of B.cinerea. After extraction, proteins were separated on 2DE gels. Spots influenced by the presence of B.cinerea in exponential and stationary phases were identified by MALDI-ToF. One hundred five and sixty spots of proteins were influenced by the presence of B.cinerea in exponential and stationary phase respectively. In exponential phase, influenced proteins were implicated in the different steps of the proteins biosynthesis: amino acid synthesis, translation or mRNA maturation and in energy synthesis. On the other hand, in stationary phase, influenced proteins were mainly implicated in energy metabolic pathway: glycolysis, alcoholic fermentation or gluconeogenesis. The presence of B.cinerea seemed to induce a slowdown in the metabolism of P.anomala without influenced its growth. Further studies have to be realized to understand the complexity of these modes of action. [less ▲]

Time-resolved small-angle X-ray scattering (SAXS) measurements performed during the formation of tetraethyl orthosilicate (TEOS) based silica gels in alcohol with 3-(2-aminoethylamino)propyltrimethoxysilane (EDAS) as an additive are reported. The measurements reveal no discontinuity of the nanostructure at the gel point. A chemically induced spinodal phase separation is found to give a coherent picture of the collected data. Increasing the amount of EDAS induces the phase separation on a smaller length scale, which finally leads to a modified gel morphology. The SAXS measurements and the electron micrographs associated with the dry gels could be interpreted in terms of the suggested wet gel formation mechanism. [less ▲]

On the legal aspect, the new European Directive on ElectroMagnetic Compatibility 2004/108/EC concerns also large machines. On a technical point of view, the special situation to characterise the EMC behaviour of large machines imply that current procedures are complex and very expensive, and in some cases even not possible. Adapted measuring methodologies and procedures are needed. As a response to this situation and within the European R&D Frameworks, the TEMCA2 project aimed to develop new and adapted methodologies for the assessment of EMC related to this type of industrial large machinery.

At the turn of the twentieth-century the portrayal of masculinity in a postcolonial context has become increasingly complex. As the remnants of empires, those most masculine of Victorian pursuits, lie decrepit, so the assurances of the old relationships are dispelled and complicated by new forms of globalisation and neo-colonisation. In this context, postcolonial masculinity, a term which is itself fraught with contention, has been figured in various ways: Saladin Chamcha, the cloven-hoofed monstrous colonial of Salman Rushdie’s The Satanic Verses, the male-dominated violence of gang-land Rio de Janeiro in Fernando Meirelles’ film City of God, the aged and sexually inert immigrant male in the later works of Hanif Kureshi, and the problematic return to an authentically historicised and indigenous male identity that Derek Walcott explores in Omeros. These examples, and many others, consider the difficulty involved in articulating a coherent and positive masculine identity in a world that is fractured and characterised by disparate social contexts that are related to colonialism. I will consider this difficulty in the work of Les Murray, an Australian poet whose exploration of masculine identity is inherently linked to his conceptualisation of national identity and Australia’s fractious racial politics. In Murray’s work postcolonial masculinity is a myth of empire-building hubris, or curtailed, victimised and essentially feminised. This is in contrast to the work of others, including the Sri Lankan/Canadian writer Michael Ondaatje, for whom some versions of postcolonial masculinity offer a potent spirituality which prevails optimistically against the bleakness of a fragmentary and brutal world. In my discussion of these writers, I will consider the implications of their representation of masculinity in a postcolonial context, and draw attention to the way in which the writers’ constructions of postcolonial masculinities which cross the borders of time, nation, gender and sexuality are deployed to represent the singularity of their own postcolonial experiences.
