The nuclear factor-kappa B (NF-kappaB) is a multipotent factor involved in many cellular processes such as inflammation, immune response and embryonic development and it can be activated by a large number of stimuli. Consequently, this transcription factor plays a pivotal role in many natural processes but also in different pathologies. For several years, photodynamic therapy (PDT) has emerged as an attractive alternative approach for the treatment of different affections involving various forms of cancer and an increasing number of reports have highlighted the activation of the NF-kappaB following PDT treatment. Furthermore, it has been shown that the mechanism of activation of the NF-kappaB as well as its target genes depends on the nature of the photosensitizers and the cell type used. As this transcription factor is known to be a key regulator of the immune response but also controls cell survival and proliferation, it is important to assess its activation status and its impact on the target genes. In this review, we will present different techniques allowing identification of the activation status of this factor, from the degradation of its inhibitor in the cytoplasm to its ability to induce the expression of a reporter gene under the control of a target promoter. As a working model we will present results obtained from a 5-aminolevulinic acid-PDT treatment on cervix adenocarcinoma cells. [less ▲]

Purpose – The purpose of this paper is to introduce a perturbation method for the A-X geometric formulation to solve eddy-current problems and apply it to the feasibility design of a non-destructive evaluation device suitable to detect long-longitudinal volumetric flaws in hot steel bars. Design/methodology/approach – The effect of the flaw is accurately and efficiently computed by solving an eddy-current problem over an hexahedral grid which gives directly the perturbation due to the flaw with respect to the unperturbed configuration. Findings – The perturbation method, reducing the cancelation error, produces accurate results also for small variations between the solutions obtained in the perturbed and unperturbed configurations. This is especially required when the tool is used as a forward solver for an inverse problem. The method yields also to a considerable speedup: the mesh used in the perturbed problem can in fact be reduced at a small fraction of the initial mesh, considering only a limited region surrounding the flaw in which the mesh can be refined. Moreover, the full three-dimensional unperturbed problem does not need to be solved, since the source term for computing the perturbation is evaluated by solving a two-dimensional flawless configuration having revolution symmetry. Originality/value – A perturbation method for the A-X geometric formulation to solve eddy-current problems has been introduced. The advantages of the perturbation method for non-destructive testing applications have been described. [less ▲]

Analysis of the high-affinity IgE receptor genes reveals epistatic effects of FCER1A variants on total IgE levels and eczema risk. Allergy 2009; DOI: 10.1111/j.1398-9995.2009.02297.x. Abstract Background: High levels of total and allergen-specific IgE levels are a key feature in allergic diseases. The high-affinity receptor for IgE, which is composed of one alpha (FCER1A), one beta (FCER1B), and two gamma (FCER1G) subunits, represents the central receptor of IgE-induced reactions. In a genome-wide association scan, we recently identified associations between functional FCER1A variants and total serum IgE levels. Previous studies had reported linkage and association of FCER1B variants with IgE and atopic traits. The FCER1G gene has not yet been investigated with regard to atopy. Filaggrin (FLG) is the strongest known risk gene for eczema, in particular the allergic subtype of eczema. Methods: We investigated the association of FCER1A, FCER1B, and FCER1G variants with IgE in a large population-based cohort (n = 4261) and tested for epistatic effects using the model-based multifactor dimensionality reduction (MB-MDR) method. In addition, we investigated a potential interaction between FLG and FCER1A variants in a large collection of eczema cases (n = 1018) and population controls. Results: Three strongly correlated FCER1A polymorphisms were significantly associated with total and specific IgE levels as well as allergic sensitization. No associations were seen for FCER1B and FCER1G. After adjustment for FLG effects, a significant epistatic effect of the FCER1A variants rs10489854 and rs2511211 on eczema risk was detected. Conclusions: These results suggest that FCER1A variants by themselves and in combination influence IgE levels and act synergistically to influence eczema risk. [less ▲]

The cyclotron of the IPNAS-CEA laboratory of the University of Liege (Belgium) has built a new high-energy, high-resolution beam line based on the use of a pair of 900 bending magnets showing a energy resolution of Delta E = 1.9 +/- 0.4 keV comparable to that of electrostatic IBA installations. In the 6-20 MeV energy range the contribution of non-Rutherford events to scattering spectra became important and are not very well known. In order to improve our knowledge in that field, a new vacuum chamber especially dedicated to differential cross-section measurements has been constructed. First results obtained with the new set-up are presented. (C) 2010 Elsevier B.V. All rights reserved. [less ▲]

Le but de ce travail est de comparer l’extraction faite par chauffage classique (CC) avec celle réalisée sous micro-ondes (MO). Deux modes d’extraction ont été réalisés : - L’hydro-distillation par chauffage classique (extraction par entraînement à la vapeur d’un solvant) et, - L’hydro-distillation activée par micro-ondes. Les MO permettent un gain de temps considérable. Par exemple, dans le cas du lavandula dentata : on note une cinétique 3 fois plus rapide, de plus le rendement est nettement supérieur (1% contre 0,6% par chauffage classique). Dans le cas de la plante fraiche, l’extraction est faite en absence de solvant sous MO. Ceci présente un grand intérêt sur le plan économique et environnemental. De plus, la qualité de l’huile extraite présente généralement une meilleure pureté. L’extraction par MO constitue une technique en accord avec la chimie verte. Grâce à ce procédé, on pourra alors réduire d'environ 60 % les besoins en énergie, ce qui diminuera d'autant les émissions de gaz à effet de serre. [less ▲]

In this study, the Single Point Incremental Forming process (SPIF) is applied on a specific aluminium alloy used in the aerospace industry since this technique and material combine a low specific weight, high strength and stiffness properties and high strain levels. To be able to optimize the process, a model and its material parameters are required. It was noticed that a simple isotropic hardening model was not sufficient to provide an accurate tool force prediction [1]. Therefore an elasto-plastic law with a mixed isotropic-kinematic hardening is investigated. The inverse method coupled with the Finite Element (FE) code: "Lagamine" [2] is used to fit the material data of this complex law. In order to validate the model and the material data, a Line test and a Cone test are used. [less ▲]

Monoterpenoid emissions from Fagus sylvatica L trees have been measured at light- and temperature-controlled conditions in a growth chamber, using Proton Transfer Reaction Mass Spectrometry (PTR-MS) and the dynamic branch enclosure technique. De novo synthesized monoterpenoid Standard Emission Factors, obtained by applying the G97 algorithm (Guenther, 1997), varied between 2 and 32 mu g g(-1)DW h(-1) and showed a strong decline in late August and September, probably due to senescence. The response of monoterpenoid emissions to temperature variations at a constant daily light pattern could be well reproduced with a modified version of the MEGAN algorithm (Guenther et al., 2006), with a typical dependence on the average temperature over the past five days. The diurnal emissions at constant temperature showed a typical hysteretic behaviour, which could also be adequately described with the modified MEGAN algorithm by taking into account a dependence on the average light levels experienced by the trees during the past 10-13 h. The impact of the past light and temperature conditions on the monoterpenoid emissions from E sylvatica L was found to be much stronger than assumed in previous algorithms. Since our experiments were conducted under low light intensity, future studies should aim at confirming and completing the proposed algorithm updates in sunny conditions and natural environments.

A finite-volume method has been developed that can deal accurately with complicated, curved boundaries for both two-dimensional and three-dimensional axisymmetric advection-diffusion systems. The motivation behind this is threefold. Firstly, the ability to model the correct geometry of a situation yields more accurate results. Secondly, smooth geometries eliminate corner singularities in the calculation of, for example, mechanical variables and thirdly, different geometries can be tested for experimental applications. An example illustrating each of these is given: fluid carrying a dye and rotating in an annulus, bone fracture healing in mice, and using vessels of different geometry in an ultracentrifuge.
