The surface ocean is everywhere saturated with calcium carbonate (CaCO[SUB]3[/SUB]). Yet increasing atmospheric CO[SUB]2[/SUB] reduces ocean pH and carbonate ion concentration and thus the level of saturation. Here we show with ocean data and models that due to this anthropogenic acidification, some surface waters will become undersaturated within decades. When atmospheric CO[SUB]2[/SUB] reaches 550 ppmv, in year 2050 under the IS92a business-as-usual scenario, Southern Ocean surface waters begin to become undersaturated with respect to aragonite, a metastable form of CaCO[SUB]3[/SUB]. By 2100 as atmospheric CO[SUB]2[/SUB] reaches 788 ppmv, undersaturation extends throughout the entire Southern Ocean (<60[SUP]o[/SUP]S) and into the surbarctic Pacific. Meanwhile, Weddell Sea surface waters also become undersaturated with respect to calcite, the stable form of CaCO[SUB]3[/SUB]. These transient changes are much larger than seasonal, interannual, and decadal variability. They threaten high-latitude aragonite secreting organisms including cold-water corals, which provide essential fish habitat, and shelled pteropods, i.e., zooplankton that serve as an abundant food source for marine predators.

The novel method described in this paper combines the use of blaI, which encodes a repressor involved in Bacillus licheniformis BlaP beta-lactamase regulation, an antibiotic resistance gene, and a B. subtilis strain (BS1541) that is conditionally auxotrophic for lysine. We constructed a BlaI cassette containing blaI and the spectinomycin resistance genes and two short direct repeat DNA sequences, one at each extremity of the cassette. The BS1541 strain was obtained by replacing the B. subtilis P(lysA) promoter with that of the P(blaP) beta-lactamase promoter. In the resulting strain, the cloning of the blaI repressor gene confers lysine auxotrophy to BS1541. After integration of the BlaI cassette into the chromosome of a conditionally lys-auxotrophic (BS1541) strain by homologous recombination and positive selection for spectinomycin resistance, the eviction of the BlaI cassette was achieved by single crossover between the two short direct repeat sequences. This strategy was successfully used to inactivate a single gene and to introduce a gene of interest in the Bacillus chromosome. In both cases the resulting strains are free of selection marker. This allows the use of the BlaI cassette to repeatedly further modify the Bacillus chromosome. [less ▲]

Ce workshop interroge la valeur ajoutée des innovations technologiques au niveau de l'efficacité de la gestion administrative du personnel. A partir de l'exemple concret d'une entreprise liégeoise, il est montré comment le recours à des solutions informatiques dédiées permet d'offrir une nouvelle gamme de services aux salariés, de confier aux salariés eux-mêmes la gestion d'une série de tâches relatives à leur dossier administratif et d'ainsi permettre au service du personnel d'avoir plus de temps pour mener à bien des initiatives de gestion des ressources humaines plutôt que d'administration du personnel. L'atelier a aussi pour but de questionner les meilleurs moyens de recourir à de telles solutions technologiques, notamment en fonction des publics cibles et des utilisateurs concernés par ce type d'innovations: cadres, employés, ouvriers, département RH, etc. [less ▲]

Atypical myopathy (AM), also called “atypical myoglobinuria”, is a frequently and rapidly fatal myopathy of unknown origin occurring sporadically in grazing horses. As opposed to the exertional rhabdomyolysis syndrome (ERS), clinical signs of AM are not induced by exercise. The condition has been reported in several European countries including Belgium, France, Germany and Great Britain. Clinical signs of AM are characterised by muscular weakness, stiffness, recumbency, sweating and when urine is observed, myoglobinuria. These signs are characteristic but not pathognomonic of the disease; the differential diagnosis of sudden weakness, severe myopathy and/or unexpected death includes several neurogenic and myopathic disorders. The main pathologies that share clinical similarities with AM include the acute form of grass sickness (GS), acute piroplasmosis, botulism, ERS, the hyperkalemic periodic paresis (HPP), nutritional myopathy (NM; i.e. vitamin E and/or selenium deficiency), plants or drugs (i.e. ionophores intoxication) intoxication, tetanus and postanaesthesia myopathy. This report aims at reviewing key facts in history, clinical signs, clinical examination and laboratory findings that contribute towards the diagnosis of AM and/or invalidate the diagnosis of other pathologies.

Le modèle MOHICAN (« Modèle hydrologique intégré pour le calcul des crues et l’amplitude des niveaux d’eau ») a été développé conjointement par l’Université de Liège (Laboratoire d’hydrodynamique appliquée, Laboratoire de Géologie de l’Ingénieur et d’Hydrogéologie, Centre d’Etude et de Modélisation de l’environnement) et la Faculté Universitaire des Sciences Agronomiques de Gembloux (Unité d’Hydraulique agricole) pour le compte et avec le support du Ministère de l’Equipement et des Transports, Service d’Etudes Hydrologiques (MET/SETHY) de la Région wallonne. En 2004, le SETHY a demandé aux développeurs du projet de simuler l’impact sur le régime hydrologique de l’Ourthe, de bassins écrêteurs dans les vallées de l’Ourthe et de l’Amblève. Plus spécifiquement, les objectifs de l’étude étaient d’estimer l’efficacité réelle de ces bassins écrêteurs (Les Combes, 16.3 Mm³, Ourthe ; Gran Han, 15.0 Mm³, Ourthe ; Stoumont, 5.7 Mm³, Amblève) pour la diminution des débits de pointe et des hauteurs d’eau, en particulier lors de très grandes crues. Dans le cas des grandes crues testée, les simulations montrent clairement la grande sensibilité des résultats aux différentes combinaisons possibles des bassins écrêteurs et surtout aux lois de gestion à utiliser pour ces bassins : il n’existe pas une loi générale qui donne un résultat maximal pour tous les types de grandes crues, et la gestion combinée des bassins est délicate.

The issue of tight glucose control with intensive insulin therapy in critically ill patients remains controversial. Although compelling evidence supports this strategy in postoperative patients who have undergone cardiac surgery, the use of tight glucose control has been challenged in other situations, including in medical critically ill patients and in those who have undergone non-cardiac surgery. Similarly, the mechanisms that underlie the effects of high-dose insulin are not fully elucidated. These arguments emphasize the need to study the effects of tight glucose control in a large heterogeneous cohort of intensive care unit patients. [less ▲]

We report results from a large set of multi-wavelength images of the quadruply imaged quasar RXS J1131-1231. We show images of this system and of the Einstein ring from the visible to the near infrared. We infer from these images an improved astrometry and we compare various simple models. Based on the flux variations observed in various filters during a 1.5 year period, we deduce two likely microlensing scenarios. Finally, we try to explain the observed chromatic variations of the flux ratios and we discuss the occurence of a flux ratio anomaly in this system. [less ▲]

A gene identical to plasmid-borne bla(CTX-M-3) is present in the chromosome of one Kluyvera ascorbata strain. It is associated with a structure including an inverted repeat right and an open reading frame 477-like gene probably involved in the mobilization of bla(CTX-M-3).

We consider random matrix models for the thermodynamic competition between chiral symmetry breaking and diquark condensation in QCD at finite temperature and finite baryon density. The models produce mean field phase diagrams whose topology depends solely on the global symmetries of the theory. We discuss the block structure of the interactions that is imposed by chiral, spin, and color degrees of freedom and comment on the treatment of density and temperature effects. Extension of the coupling parameters to a larger class of theories allows us to investigate the robustness of the phase topology with respect to variations in the dynamics of the interactions. We briefly study the phase structure as a function of coupling parameters and the number of colors. [less ▲]

PURPOSE: The aim of the study is to evaluate the effect of different acidic compounds on the inclusion of miconazole (MICO) in several cyclodextrins (CDs) using supercritical carbon dioxide (SCCO(2) ) processing. METHODS: Physical mixtures were processed by SCCO(2) at 30 MPa, 125 degrees C during 60 minutes in a static mode to produce inclusion complexes. The inclusion complexes were characterized by differential solubility, Fourier transform infrared spectroscopy (FT-IR) and dissolution test. RESULTS: The best inclusion yields were achieved with the combination of MICO base and HPgammaCD with or without acids. Maleic and fumaric acids influenced the MICO inclusion differently in function of their conformation. During the process, a miconazole salt was observed with maleic acid and characterized by thermal analysis and mass spectrometry. The kinetics inclusion followed a saturation-type shape curve. FT-IR confirmed the presence of genuine inclusion complexes. The complexes MICO base/HPgammaCD/(L-tartaric acid) enhanced the dissolution rates of MICO more than the corresponding physical mixtures did. Lastly, the stability study revealed that the complexes were stable. CONCLUSIONS: The formation of stable complexes between MICO and CDs is possible using SCCO(2). Moreover an acidic ternary compound is able to modify the formation of the complex. The inclusion complexes, which show better dissolution profiles than those with the corresponding physical mixtures, could lead to an increase of the oral bioavailability of MICO. [less ▲]

In Japanese quail (Coturnix japonica), activation of appetitive and consummatory aspects of male sexual behavior requires aromatization of testosterone (T) into estrogens. Appetitive male sexual behavior (ASB) is usually assessed with the use of a learned social proximity procedure. In the present experiment, we investigated the role of estrogens in the activation of an another index of ASB. the female-induced activation of rhythmic cloacal sphincter movements (RCSMs) that are produced in reaction to the visual presentation of a female. Consummatory sexual behavior (CSB) was also assessed by the frequency and latency of copulatory behaviors. Castrated male quail were treated with Silastic implants filled with T in association with chronic injections of the aromatase inhibitor Vorozole(TM) (R83842; 1 mg/kg twice a day; CX + T + VOR group). Control birds were implanted with T capsules only (CX + T group). CSB was almost completely blocked by injections of the aromatase inhibitor. The RCSM frequency decreased progressively in the CX + T + VOR group by comparison with the CX + T group and was therefore significantly reduced at the end of the experiment. These results demonstrate that the frequency of RCSM, a second measure of ASB is, like the social proximity response and CSB, blocked by inhibition of estrogen production. It was shown previously that lesions of the preoptic area inhibit both aspects of the appetitive sexual behavior (proximity response and RCSM). It is therefore, likely that both responses are controlled, like copulation, by aromatase-containing neurons of the preoptic area. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]
