We present the results of a study of the host galaxies of a few bright low redshift quasars, based on a combination of high resolution HST/ACS images with deep VLT spectra. Using a version of the MCS deconvolution algorithm specially adapted to HST images, the light from the central point source can be efficiently removed, which allows to study the environment of the quasar down to a few hundreds of parsecs from the center. In a similar way, the spectra can be separated into a quasar contribution and a spatialy resolved slit spectrum of the host galaxy. Combinig the images and spectra allows to carry out a detailed analysis of the immediate environment of the quasar: excitation and ionisation state of the gas, dynamics... Up to now, this method has been applied to six quasars, including the peculiar HE0450-2958 for which no host galaxy could be detected. [less ▲]

The RNA distribution in Ehrlich tumour cell nucleoli has been investigated using RNase-gold method. This technique has been applied to sections of cells prepared under various fixation and embedding conditions. As expected, the specificity and intensity of labelling by gold particles have varied according to the experimental conditions used. Interestingly, however, it has been noted that the localization of gold particles does also vary and in particular within the fibrillar centre. This observation underlines the interest of assaying the RNase-gold complex under various conditions. The gold particles were particularly concentrated over the granular component and to a lesser extent, in the dense fibrillar component. In the latter constituent, it has been noted that the gold markers were preferentially localized at the edge of the dense fibrils. Surprisingly, a few gold particles have also been detected in the fibrillar centres. The weak labelling has persisted even after pepsin or DNase extraction but has completely disappeared after RNase extraction. Further, an inhibition of rRNA synthesis by a treatment with actinomycin D has not produced a significant decrease of the number of gold particles present in the fibrillar centre. These results suggest that fibrillar centres contain a small amount of RNA which would not correspond to pre-rRNA. [less ▲]

Methylmercury (MeHg) and selenium (Se) can be found at elevated concentrations in blood of marine mammals and both display modulatory effects on the immune system. Whereas mercury (Hg)-Se antagonism in liver of marine mammals is well known, the protective role of Se against Hg immunotoxicity in marine mammals has been poorly described. We propose here an in vitro approach using combined Hg and Se in vitro exposure of peripheral blood mononuclear cells (PBMCs) of the harbor seal (Phoca vitulina). PBMCs were isolated from the blood of 10 harbor seals and exposed to environmental concentrations of MeHg (1µM) and selenite or selenomethionine (5µM), respectively inorganic and organic forms of Se. MeHg leaded to a decrease of lymphocyte proliferation, to an increase of cells with compromised mitochondrial membrane potentials and cell death. Preliminary results evidenced that none of the two Se forms had a protective effect against MeHg toxicity, although cells were slightly stimulated by Se alone. Therefore MeHg expresses its toxicity among blood circulating lymphocytes in presence or absence of selenite or selenomethionine. [less ▲]

This paper reports a study on the progeny sex-ratio distribution in the Florida red tilapia. This hybrid originated as a cross between O. mossambicus male and O. urolepis hornorum female, which was then crossed with 0. niloticus and 0. aureus in order to improve its growth rate and its resistance to low temperature. We have studied the sex-ratio of I I I progenies from 46 females and 12 males, where the male percentage varied between 5% to 89%. The analysis of distribution showed three groups characterised by a mean male percentage of 26.7 +/- 9.81; 50.0 +/- 8.9 and 70.3 +/- 5.5%. The stability of sex ratios in repeated single pair matings and the parental influence on progeny sex ratios obtained are in agreement with a polygenic basis of sex determination in this complex hybrid.

Models and simulations are very useful to study interactions between anatomic structures and physical cardiac phenomena. In this work, we are interested in models of the instantaneous pressure-volume relationship, i.e. isochrone models. More precisely, we concentrate on the 6 models considered by Lankhaar et al. [1]. We propose a critical analysis of the work of these authors and suggest some improvement of their procedure. [1] Lankhaar J.-W. et al.

The influence of the six major alloying elements: carbon, chromium, cobalt, molybdenum, titanium, and aluminum on the solidification sequence of nickel-base superalloys was investigated. The microstructure was found to depend greatly on aluminum and titanium contents. During solidification the liquid is enriched in titanium and molybdenum, whereas the dendrite cores are richer in cobalt. Aluminum and chromium segregate in the liquid or in the dendrite center, depending on alloy nominal composition. Chemical analysis of the carbides showed that their composition changes during solidification, thus affecting the composition of the residual liquid. The composition of carbides is strongly influenced by titanium and molybdenum nominal content in the alloy. Statistical analysis of the transformation temperatures obtained by DTA showed that titanium and aluminum influence the entire solidification sequence. [less ▲]
