Proton pump inhibitors are among the most prescribed drugs in Belgium, due to the high prevalence of gastrooesophageal reflux disease and significant impairment of health-related well-being. Short-term and long-term efficacy is superior to that of H2-receptor antagonists. Long-term safety is established. Empirical short-term treatment of symptomatic patients under 50 years of age without alarm signs is acceptable, but endoscopic investigation should always be performed before starting a long-term treatment. Doses for management of low-grade oesophagitis may be tailored to the patient's response. Continuous maintenance of full-dose is recommended for high grade oesophagitis. Surgical alternative is to be discussed with patients. Efficacy and mean cost for insurance plans are comparable. Endoscopic procedures are not yet sufficiently evaluated to be considered. Simple lifestyle advice is still useful. The burden of proton pump inhibitors cost is acceptable if they are prescribed at adequate doses. Cost-effective drugs should be chosen first. [less ▲]

The Hilbert-Huang transform (HHT) has been shown to be effective for characterizing a wide range of nonstationary signals in terms of elemental components through what has been called the empirical mode decomposition. The HHT has been utilized extensively despite the absence of a serious analytical foundation, as it provides a concise basis for the analysis of strongly nonlinear systems. In this paper, we attempt to provide the missing link, showing the relationship between the EMD and the slow-flow equations of the system. The slow-flow model is established by performing a partition between slow and fast dynamics using the complexification-averaging technique, and a dynamical system described by slowly-varying amplitudes and phases is obtained. These variables can also be extracted directly from the experimental measurements using the Hilbert transform coupled with the EMD. The comparison between the experimental and analytical results forms the basis of a nonlinear system identification method, termed the slow-flow model identification method, which is demonstrated using numerical examples.

We discuss recent observational evidence illustrating the current limitations plaguing classical LTE abundance analyses of cool (T [SUB]eff[/SUB] < 5500 K), chromospherically active stars. Although significant progress on this issue can be evidently expected from a more realistic atmospheric modelling and treatment of NLTE line formation, a homogeneous abundance study of a large sample of inactive K-type stars may also prove valuable in disentangling temperature and activity effects.

Histone-deacetylase inhibitors (HDCACi) represent a new class of antitumor agents currently in clinical development. They target a family of enzymes which catalyse histone acetylation modifications, in particular for histones H2A, H2B, H3 and H4. These proteins stabilize the nucleosome core, fundamental unity of chromatin which represents the first level of DNA nuclear compaction. The balance of histone acetylation is maintained by histone-acetyltransferases (HAT) and histone-deacetylases (HDAC) which play an important role in gene transcription. Alterations of HDACs were identified in tumor cells and contribute to the massive perturbations of gene expression in numerous tumors. HDAC inhibition leads to differentiation, cell cycle arrest and apoptosis in tumor cells. HDACi efficiently prevent tumor growth in a variety of in vivo preclinical models. Several structurally distinct classes of HDACi have entered in clinical trials and a significant antitumor activity was reported in several cases. However, a better understanding of the biological effects of this class of enzymes is mandatory for the successful development of these new antitumoral agents. In this review, are exposed the main drug candidates in clinical development. In the near future, it will be interesting to define direct relationships between specific inhibition of one or several HDAC and the subsequent HDAC-dependent antitumor effects to define a new generation of specific histone-deacetylase inhibitors.

Oil reservoir rocks contain various immiscible fluids (oil, water and gas) and they are submitted to elevated temperatures in the oilfield. Hence, they exhibit a typical coupled behaviour where multiphysics and coupled Thermo-Hydro-Mechanical aspects are predominant. This paper presents some results from researches carried out within the PASACHALK 2 European funded collaborative research. In this research dedicated to subsidence problems in the North sea Ekofisk oilfield, the behaviour of a reservoir chalk containing two immiscible fluids (an organic non polar fluid and water) is considered within the framework of the mechanics of unsaturated soils (no temperature effects considered). In order to account for the mechanical coupled effects related to the two pore fluids, the oil-water suction was considered as an independent stress variable. The paper presents some experimental results describing the combined effect of suction and time on the isotropic compression behaviour of the chalk. A viscoelastoplastic constitutive model based on one hand on the Barcelona BBM elastoplastic model for unsaturated and on the other hand on Perzina’s approach of viscous behaviour of soils is also presented and validated against experimental evidence.

Cet article porte sur l’efficacité politique d’une série photographique qui problématise des questions socioculturelles contemporaines telles l’immigration, l’exploitation et l’éthique du travail. L’image photographique devient une ressource dans les mains des acteurs sociaux et fait fonction de diagnostic des tensions du contemporain. La photographie permet de «reconnaître à travers» (c’est-à-dire « diagnostiquer ») et de formuler des jugements. Le potentiel sémantique du diagnostic engendré par cette série et la force illocutoire des jugements qui y sont inscrits fonctionnent comme une sorte d’« argumentation par images ». L’analyse de cette série photographique, réalisée par le photographe et théoricien Allan Sekula, nous a amené à nous interroger sur la relation entre image, corpus, genres d’afférence et statuts (documentaire et artistique).

The increased concern about environmental effect of off-target deposits of pesticides use has resulted in the development of numerous spray drift models. Statistical models based on experimental field studies are used to estimate off-target deposits for different sprayers in various environmental conditions. Random-walk and computational fluid dynamics (CFD) models have been used to predict the effect of operational parameters and were extensively validated in wind tunnel. A third group, Gaussian dispersion models have been used for several years for the environmental assessment of the pesticide spray drift, mainly for aerial application. When these models were used for the evaluation of boom sprayer spray drift, their predictions were found unreliable in the short range, were the initial release conditions of the droplets have a significant effect on the spray deposits. For longer ranges, the results were found consistent with the field measurements as the characteristics of the source have a reduced influence on the small droplets drift. Three major parameters must be taken into account in order to define realistic initial conditions of the droplets in a spray drift model: the spray pattern of the nozzle, the boom movements and the effect of entrained air and droplet velocities. To take theses parameters into account in a Gaussian model, the nozzle droplet size distribution measured with a Malvern laser particle analyser was used to divide the nozzle output into several size classes. The spray deposits of each diameter class was computed for each successive position of the nozzle combining the nozzle spray distribution with drift computed with a Gaussian tilting plume model. The summation of these footprints resulted in the global drift of the nozzle. For increasing droplet size, the release height used in the Gaussian model was decreased from nozzle height to ground level using an experimental law to take into account the effect of entrained air and droplet initial velocity. The experimental law was adjusted on 2m/s wind tunnel measurements and robustness was evaluated for 1 and 4 m/s. [less ▲]
