Metallothioneins (MTs) were characterised in the kidneys of a white-sided dolphin Lagenorhynchus acutus stranded along the Belgian coast, displaying high levels of cadmium (Cd) and mercury (Hg) in liver and kidney. The protein has two isoforms: MT-1 and MT-2. MT-1 binds Cu, Zn, Hg and Cd, while MT-2 only binds Zn, Hg and Cd. This suggests different metabolic functions for the two isoforms: MT-1 is mainly involved in Cu homeostasis; MT-2, which was fourfold more abundant than MT-1, detoxifies most of the accumulated cadmium.

A series of gastro-intestinal diseases exhibits some connection with various cutaneous lesions. Some skin manifestations are clinically or histologically evocative, while others lack specificity. These manifestations can occur in overt digestive disease or be the clue for a silent one. A careful skin examination can thus reveal some inflammatory or neoplastic diseases of the gastro-intestinal tract, a malabsorption syndrome or food intolerance. [less ▲]

Subsidence of chalk oil reservoirs in North Sea is related to the chalk compaction induced by fluid depletion and by the water – chalk interaction. A constitutive model is developed in order to take into account these two effects. It is based on frictional – cap elastoplasticity and on the Barcelona unsaturated soil model. Oil – water – chalk interaction is modeled through the suction variable. In a second step, viscous effects are added to the model. After implementation into a finite element code, these tools allow to simulate a waterflooding experiment on a chalk sample. The model appears to reproduce qualitatively and quantitatively the experimental results. [less ▲]

La lutte contre le ragondin, espèce importée d'Amérique du Sud en Europe, aujourd'hui classée parmi les espèces invasives, a été inscrite simultanément dans deux législations différentes. Dans le mondeagricole, c'est une action qui s'inspire de la guerre contre les ravageurs des cultures. Elle s'organise collectivement à l'aide d'un poison, la bromadiolone. Dans le monde de la chasse, elle est principalement du domaine des piégeurs. Solitaires, ceux-ci pourchassent le ragondin en tant qu'espèce nuisible. Cette division est héritée du Moyen Âge, de ses usages de l'espace et des droits qui leur étaient associés (droit de destruction pour les agriculteurs). Actuellement, l'espace rural peut être vu comme une mosaïque, òu ces deux principaux types de lutte coexistent, alors que certains milieux restent libres de toute intervention. Mais ces actions sont aussi l'objet de critiques qui mettent en cause l'utilisation de la bromadiolone et certaines formes de piégeage. Et aujourd'hui, on observe que les modalités de lutte contre le ragondin se combinent aux nouveaux usages de l'espace. [less ▲]

Electrospray mass spectrometry was evaluated regarding the reliability of the determination of the stoichiometries and equilibrium association constants from single spectra. Complexes between minor groove binders (Hoechst 33258, Hoechst 33342, DAPI, netropsin and berenil) and 12mer oligonucleotide duplexes with a central sequence (A/T)(4) flanked by G/C base pairs were chosen as model systems. To validate the electrospray ionization mass spectrometry (ESI-MS) method, comparisons were made with circular dichroism and fluorescence spectroscopy measurements. ESI-MS allowed the detection of minor (2 drug + DNA) species for Hoechst 33258, Hoechst 33342, DAPI and berenil with duplex d(GGGG(A/T)(4)GGGG). d(CCCC(A/T)(4)CCCC), which were undetectable with the other techniques. Assuming that the duplexes and the complexes have the same electrospray response factors, the equilbrium association constants of the 1:1 and 2:1 complexes were determined by ESI-MS, and the values show a good quantitative agreement with fluorescence determined constants for Hoechst 33258 and Hoechst 33342. It is also shown that ESI-MS can quickly give reliable information on the A/T sequence selectivity of a drug: the signal of a complex is directly related to the affinity of the drug for that particular duplex. The potential of ESI-MS as a qualitative and quantitative affinity screening method is emphasized. [less ▲]

Various cavities studied in western Niger and South Cameroon show the existence of important karstic phenomena into metagabbros and gneisses. These large-sized eaves resulted from generalized dissolution of silicate formations in spite of their low solubility. Karstification is produced by deep hydrous transfer along lithological discontinuities and fracture net works. The existence of such caves has major implications in geomorphology, under either Sahelian and Equatorial climate, and in hydrogeology and water supply, particularly in the Sahel area. [less ▲]

Some lactonic aroma compounds, that can be produced industrially by microorganisms, become toxic towards the producing cells as these compounds reach high concentrations in the culture medium. To determine the manner by which these metabolites may influence yeast physiology, the effects of four lactones (concentration range of 100 to 300 mg l-1) on the growth of Yarrowia lipolytica and on the phase behaviour of deuterated dimyristoylphos-phatidylcholine (DMPC-d27) were studied. The results showed that the hydrophobic lactones decrease the phase transition temperature (Tm) of DMPC-d27 bilayers and that Tm decrease (ΔTm) was related to the inhibitory action of the lactones on yeast growth (evaluated by the lag time). These results suggest that whatever the lactone, a ΔTm of at least 2.5°C resulted in a total growth inhibition: this implicates the lactone-phospholipids interaction in the mechanism of yeast growth inhibition. The test used in the present study may be a predicting method to assess the in vivo action of potential membrane active compounds. [less ▲]

alpha-cyclodextrin complexes with linear alpha,omega-dicarboxylic acids were investigated by electrospray mass spectrometry. These hydrophobic complexes are known to have an equilibrium binding constant that increases with the diacid chain length. However, the electrospray mass spectrometry (ES-MS) spectra showed that the relative intensity of the complex did not vary significantly with chain length. This contradiction is caused by a contribution of nonspecific adducts to the signal of the complex in ES-MS. In order to estimate the contribution of nonspecific adducts to the total intensity of the complexes with alpha-cyclodextrin, the comparison was made between alpha-cyclodextrin and maltohexaose, the latter being incapable of making inclusion complexes in solution. The signal observed for complexes between diacids and maltohexaose can only result from nonspecific electrostatic aggregation, and is found to be more favorable with the shorter diacids. This is also supported by MS/MS experiments. A procedure is described which allows estimation of the contribution of the nonspecific complex in the spectra of the complexes with alpha-cyclodextrin by using the relative intensity of the complex with maltohexaose. The contribution of the specific complex to the total signal intensity is found to increase with the diacid chain length, which is in agreement with solution behavior. [less ▲]
