In the frame of XMM testing, all the mirror modules have been illuminated by a vertical EUV collimated beam a the Centre Spatial de Liege. A mirror module consists in 58 co- focal and co-axial Wolter I mirrors. Up to now the images obtained at CSL have been used to assess the Mirror Module optical performances in a flight representative configuration, and also to verify the impact of the thermal environmental and vibration test on the optical performance. Due to the highly complex design of the Mirror Modules, simulating XMM images in details is very difficult. The Point Spread Function of some of the mirror modules presents slight asymmetry. In the facility design study, it has been demonstrated that the diffraction impact at 58.4 nm is negligible with respect to the half energy width mirror module specification. Presently all the mirror modules are better than 165 arcsec. This paper presents first the diffraction contribution on the image. In a second step a point spread function is built by using the metrological mirror shell data. EUV images are then analyzed to evaluate the impact of the mirror interface structure integration process on the PSF. An analytical model of the measured EUV pSF is developed. The modelization technique is applied to simulate in-orbit image. Finally the different modelizations are evaluated and compared. [less ▲]

• Photosynthetic organisms have evolved various photoprotective and regulatory mechanisms to cope with changing and high light intensities. The nature and relative amplitude of these mechanisms is matter of debate in dinoflagellates that live in symbiosis with cnidarians. In this work, the amplitude of photosynthetic alternative electron flows to oxygen (chlororespiration, Mehler reaction, mitochondrial respiration) and PSI cyclic electron flow were investigated in Symbiodinium clades A1, B1 and F1. • Cultured Symbiodinium strains were maintained semi-continuously under identical environmental conditions. Joint measurements of oxygen evolution, fluorescence emission, and absorption changes at specific wavelengths were used to evaluate PSI and PSII electron transfer rates (ETR). • A light-dependent and O2-dependent ETR was observed in all strains. This ETR involved PSII and PSI and was insensitive to addition of mitochondrial and carbon fixation inhibitors. • These results demonstrate that photoreduction of oxygen downstream of PSI by the so-called Mehler reaction is the main alternative electron sink at the onset and steady state of photosynthesis in all strains. This mechanism in Symbiodinium sustains significant levels of photosynthetic electron flux under high light, thus acting as a photoprotective mechanism and increasing the ATP/NADPH ratio by the electron transfer chain.

Notre pays compte quelques 300 000 personnes atteintes de psoriasis, une maladie inflammatoire chronique de la peau. Elle se caractérise par des plaques de couleur rouge foncé, couvertes de squames argentées ou blanches, que l'on observe surtout sur le crâne, au niveau de la face d'extension des coudes et des genoux, dans le bas du dos, sur les jambes, les bras et les pieds.

Psoriasis is a frequent multifactorial chronic skin disease that can lead to a decreased quality of life. Some patients also present arthritis. Those two complex inflammatory diseases share some of their characteristics, but several clinical manifestations can be distinguished in each of them. In addition to classical medications (constituted of topical treatments, methotrexate, ciclosporin and retinoids for cutaneous psoriasis and non steroidal anti-inflammatory drugs or methotrexate for psoriatic arthritis), they are the target of a new generation of therapies: the biologics.

OBJECTIVE: Unconfounded differences in inherent vulnerability to metabolic disturbance may be hypothesized for different diagnostic groups with severe mental illness. METHOD: A naturalistic cohort of patients diagnosed with DSM-IV bipolar disorder (N = 112), schizophrenia (N = 503), and schizoaffective disorder (N = 92) were assessed for metabolic disturbances. The prospective inclusions started in November 2003 and were concluded in July 2007. RESULTS: Diagnosis was strongly associated with the metabolic syndrome (chi(2) = 14.90, df = 2, p < .001). Compared with bipolar patients, the unadjusted risk for metabolic syndrome was significantly higher for schizoaffective (odds ratio [OR] = 3.51, p < .0001) but not for schizophrenia patients (OR = 1.58, p = .094). Differences were not reducible to confounding factors including treatment. Rather, the difference between bipolar and schizophrenia patients also reached significance after adjustment (OR = 1.97, p = .046). Furthermore, the association between diagnosis and glucose dysregulation was significant (chi(2) = 6.97, df = 2, p = .031), with a significantly higher risk in schizoaffective (unadjusted OR = 2.12, p = .022) but not in schizophrenia patients (unadjusted OR = 1.13, p = .640) compared with bipolar patients. Diagnostic differences in glucose dysregulation were in part mediated by body mass index (BMI). CONCLUSIONS: Schizoaffective patients in particular may be at risk for metabolic disturbances compared with bipolar and schizophrenia patients. Differences were not reducible to known metabolic risk factors and could only be explained in part by higher BMI in schizoaffective patients, suggesting an increased inherent vulnerability in this group.
