"Bonjour. Bienvenue dans cette nouvelle édition de E = 48 FM c2, l'émission radio de vulgarisation scientifique de l'ULg. Aujourd'hui, nous recevons Thérèse Scali, chercheuse en psychologie au Département Psychologies Cliniques et Systèmes Humains, chez le Professeur D'Amore. Une ouverture, pour nous et cette émission, vers les sciences humaines. Avec Maud Brasseur et Marc Henri Bawin en studio, cette édition va dérouler en trois temps mais, à la demande de notre invitée, sur une structure différente. Exit donc les simplicius et décodage. Nous allons commencer par une présentation du contexte social, politique et surtout législatif qui est particulièrement propice aux recherches de Thérèse Scali. Ensuite, nous allons aborder la méthode de recherche utilisée en sciences humaines et sociales : une approche quantitative ou qualitative. Enfin, nous aborderons les résultats auxquels, après deux ans de thèse, elle peut déjà prétendre." [less ▲]

This study presents a Bayesian approach for the parameters’ identification of the STICS crop model based on the recently developed Differential Evolution Adaptive Metropolis (DREAM) algorithm. The posterior distributions of nine specific crop parameters of the STICS model were sampled with the aim to improve the growth simulations of a winter wheat (Triticum aestivum L.) culture. The results obtained with the DREAM algorithm were initially compared to those obtained with a Nelder-Mead Simplex algorithm embedded within the OptimiSTICS package. Then, three types of likelihood functions implemented within the DREAM algorithm were compared, namely the standard least square, the weighted least square, and a transformed likelihood function that makes explicit use of the coefficient of variation (CV). The results showed that the proposed CV likelihood function allowed taking into account both noise on measurements and heteroscedasticity which are regularly encountered in crop modelling [less ▲]

Parabens, benzophenone-3 (BP3) and phthalates are commonly used as antimicrobial conservator, UV-filter and plasticizer respectively, and are thought to exhibit endocrine disrupting properties. These endocrine disrupting activities have been recently assumed to lead to cutaneous malignant melanoma. Humans are exposed to these chemicals through different sources such as food, personal care products or cosmetics. In this study we measured urinary levels of 4 parabens, BP3 and 7 metabolites of phthalates in samples collected from 261 participants living in and around Liege (Belgium). The analyses were carried out by liquid chromatography tandem mass spectrometry (LC-MS/MS) using isotopic dilution. To the best of our knowledge, this is the first time that the urinary levels of these 3 classes of chemicals are reported for the same general population in Belgium. Most of the parabens, the BP3 and all the phthalate metabolites were detected in 82.8 to 100.0% of the samples. For most of these chemicals, the exposure patterns significantly differ between children and adults, but also between males and females, especially with higher concentrations of parabens and phthalate metabolites in female and children subjects respectively.

In this review, we summarize the knowledge pertaining to the role of epigenetics in the regulation of angiogenesis. In particular, we show that lysine acetylation and cytosine methylation are important transcriptional regulators of angiogenic genes in endothelial cells. Lysine acetylation and cytosine methylation inhibitors idiosyncratically tune the transcriptome and affect expression of key modulators of angiogenesis such as VEGF and eNOS. Transcriptomic profiling also reveals a series of novel genes that are concomitantly affected by epigenetic modulators. The reversibility and overall tolerability of currently available epigenetic inhibitors open up the prospect of therapeutic intervention in pathologies where angiogenesis is exacerbated. This type of multitargeted strategy has the major advantage of overcoming the compensatory feedback mechanisms that characterize single anti-angiogenic factors. [less ▲]

We present a detailed analysis of survey and follow-up observations of microlensing event OGLE-2012-BLG-0406 based on data obtained from 10 different observatories. Intensive coverage of the lightcurve, especially the perturbation part, allowed us to accurately measure the parallax effect and lens orbital motion. Combining our measurement of the lens parallax with the angular Einstein radius determined from finite-source effects, we estimate the physical parameters of the lens system. We find that the event was caused by a $2.73\pm 0.43\ M_{\rm J}$ planet orbiting a $0.44\pm 0.07\ M_{\odot}$ early M-type star. The distance to the lens is $4.97\pm 0.29$\ kpc and the projected separation between the host star and its planet at the time of the event is $3.45\pm 0.26$ AU. We find that the additional coverage provided by follow-up observations, especially during the planetary perturbation, leads to a more accurate determination of the physical parameters of the lens.

The BODE index is well-validated for mortality prediction in COPD. Concentrations of plasma proadrenomedullin, a surrogate for mature adrenomedullin, independently predicted 2-year mortality among inpatients with COPD exacerbation.We compared accuracy of initial proadrenomedullin level, BODE, and BODE components, alone or combined, in predicting 1-year or 2-year all-cause mortality in a multicenter, multinational observational cohort with stable, moderate to very severe COPD.Proadrenomedullin was significantly associated (P<0.001) with 1-year mortality (4.7%) and 2-year mortality (7.8%), and comparably predictive to BODE regarding both (C statistics: 0.691 vs. 0.745, 0.635 vs. 0.679). Relative to using BODE alone, adding proadrenomedullin significantly improved 1-year and 2-year mortality prognostication (C statistics: 0.750, 0.818; both P<0.001). Proadrenomedullin plus BOD was more predictive than was the original BODE including 6-minute-walk distance. In multivariable analysis, proadrenomedullin (LR X2 13.0, P<0.001), body mass index (8.5, P=0.004), and 6-minute-walk distance (7.5, P=0.006), but not modified MMRC dyspnoea score (2.2, P=0.14) or FEV1 % predicted (0.3, P=0.60), independently foretold 2-year survival.Proadrenomedullin plus BODE better predicts mortality in COPD patients than does BODE alone; proadrenomedullin may substitute for 6-minute-walk distance in BODE when 6-minute-walk testing is unavailable.
