The mammary tissue is characterized by its capacity to adapt in response to a wide variety of changing conditions. This adaptation capacity is referred to as the plasticity of mammary tissue. In dairy ruminants, lactation is challenged by modifications that can either be induced on purpose, such as by modifying management practices, or occur involuntarily, when adverse environmental constraints arise. These modifications can elicit both immediate changes in milk yield and composition and carryover effects that persist after the end of the challenge. This review focuses on the current knowledge concerning the cellular mechanisms underlying mammary tissue plasticity. The main mechanisms contributing to this phenomenon are changes in the activity and number of mammary epithelial cells (MECs). Changes in the number of these cells result from variations in the rates of cell proliferation and death as well as changes in the rate MEC exfoliation. The number of MECs also depends on the number of resident adult mammary stem cells and their progenitors, which can regenerate the pools of the various mammary cells. Several challenges, including changes in milking frequency, changes in level of feed supply and hormonal manipulations, have been shown to modulate milk yield together with changes in mammary cell activity, turnover and exfoliation. Epigenetic changes may be an additional mechanism of adaptation. Indeed, changes in DNA methylation and reductions in milk yield have been observed during once-daily milking and during mastitis in dairy cows and may affect cell activity persistently. In contrast to what has been assumed for a long time, no carryover effect on milk yield were observed after feed supply challenges in dairy cows and modification of milking frequency in dairy goats, even though the number of mammary cells was affected. In addition, mammary tissue plasticity has been shown to be influenced by the stage of lactation, health status and genetic factors. In conclusion, the cellular mechanisms underlying mammary tissue plasticity are diverse, and the mammary tissue either does or does not show elastic properties (with no permanent deformation), in response to environmental changes.

Zussmanite KFe13[AlSi17O42](OH)14, a modulated 2:1 layer silicate, has so far been found only in iron-rich metasediments from Laytonville, California (Agrell et al.), 1965). A new occurrence is reported here from Punta Nihue north of Valdivia, Chile, in banded stilpnomelane-schists. These are intercalated in the ‘Western Series’, a complex of low-grade metamorphic rocks with local high-pressure, low-temperature overprint (e.g. blueschists).
The rock contains conspicuous porphyroblasts of zussmanite of mm size and is composed of chemically distinct bands with the subsequent assemblages: (1) zussmanite-stilpnomelane-quartz, (2) siderite-quartz±stilpnomelane (3) apatite-stilpnomelane-quartz±siderite. The chemical composition of zussmanite, (K0.80Na0.05Ba0.01)(Fe11.292+Mg1.11Mn0.25Fe0.143+Cr0.01Al0.19Ti0.01)[Al1.23Si16.77O42](OH)14, its optical properties and X-ray data correlate well with the Californian occurrence. Additionally, we present new IR data. In type (2) bands of fine-grained crystals of a K,Al poor mineral formed from siderite and quartz. Its chemical composition is close to that of zussmanite. A similar phase was also reported from Laytonville, California (Muir Wood, 1980).
The rarity of rock-forming zussmanite can be explained by its occurrence in strongly Fe-rich and reduced rocks, as well as, by a possibly narrow P-T stability field.

More and more, youth suicide in the Inuit community is gaining importance, with a frequency in Greenland rising from 14.4 (1960–64) to 110.4 per 100,000 person-years (2010–11). The huge cultural/educational changes during the last 20 years and the role of globalization, especially of the occidental influence on this community may be at the origin of such an “epidemics” of suicide in this cultural region. Recently, a political organization representing the Inuit community in Canada (ITK for Inuit Tapiriit Kanatami) launched a National Inuit Suicide Prevention Strategy (NISP) based on the specificities of this community in comparison to the occidental civilization. In fact, not only the Canadian Inuit community is concerned by this epidemics of suicide, but also many other autochthonous groups. In this context, the European Psychiatric Association (EPA) guidance on suicide treatment and prevention needs to be adjusted to autochthonous individuals’ needs.

In order to investigate further the interest of using the Chilean gene pool in potato breeding programmes, the genetic diversity and population structure of a collection of Solanum tuberosum L. genotypes including 350 worldwide varieties or breeders' lines (referred to as the modern group) and 30 Chiloé Island landraces were examined using simple sequence repeat markers. The close genetic proximity of the Chiloé Island landraces to the modern group was confirmed using several structure analysis methods: principal coordinate analysis; hierarchical clustering analysis; analysis of molecular variance; Bayesian model-based clustering analysis. The latter analysis, in particular, revealed no clear genetic structure between the modern group and the Chiloé Island landraces. The Chiloé Island germplasm appears to represent an interesting gene pool that could be exploited in potato breeding programmes using an association mapping approach.

Experimental huts in Côte d’Ivoire were used to evaluate the pyrethroid alpha-cypermethrin, the non-ester pyrethroid etofenprox, the organophosphate pirimiphos-methyl and the carbamate carbosulfan on bednets against pyrethroid-resistant Anopheles gambiae Giles. To test for selection for the resistance gene by the treated nets, A. gambiae collected live or dead from the huts were kept and analysed for the presence of the kdr gene using a new polymerase chain reaction followed by sequence-specific oligonucleotide probing (PCR–SSOP) for kdr-genotyping. Deliberately holed bednets freshly treated with pirimiphos-methyl or carbosulfan caused over 90% kill of A. gambiae s.s. and Culex spp. However, the mortality with alpha-cypermethrin or etofenprox treated nets was similar to that with untreated nets. Bloodfeeding of A. gambiae s.s. on the sleepers under the nets was only significantly reduced by alpha-cypermethrin and carbosulfan. Tests of the residual activity of the bednets after seven months showed that pirimiphos-methyl had lost its efficacy while carbosulfan still performed well. Once again the pyrethroid treated nets gave similar results to the untreated nets. Selection for the kdr-allele by alpha-cypermethrin and etofenprox, but not by carbosulfan, was indicated by PCR–SSOP genotyping of mosquitoes. Thus carbamates such as carbosulfan, or organophosphates of longer persistence than pirimiphos-methyl and of low mammalian toxicity, would seem to be a promising alternative to be used on bednets, particularly in areas of pyrethroid resistance.

Quelles sont les valeurs qui caractérisent sur le territoire français les rayonnements ionisants et les radionucléides d'origine naturelle ? Comment distinguer dans le résultat d'une mesure la part qui résulte éventuellement d'une activité humaine ? Afin d'essayer de répondre à ces questions, un questionnaire a été adressé aux différents organismes qui effectuent en France des mesures de radioactivité dans l'environnement. Les informations mentionnées dans cette étude se rapportent exclusivement à des observations faites dans l'environnement à l'extérieur des bâtiments et du périmètre des installations nucléaires de base (INB). En outre, elles ne concernent, sauf cas particuliers signalés, que des mesures de rayonnements ou de radioéléments d'origine naturelle dont les résultats n'ont pas été perturbés par l'action de l'homme. L'enquête montre la difficulté actuelle de dresser en France un bilan exhaustif des connaissances acquises concernant les caractéristiques du bruit de fond radioactif d'origine naturelle dans l'environnement. Aujourd'hui en France, dans le domaine de la radioactivité naturelle, les efforts consentis manquent de coordination et d'orientation vers certaines priorités. À ce titre, les mesures des 238U et 232Th précurseurs des 226Ra et 228Ra, des descendants solides émetteurs alpha du radon (par la mesure des EAP du 222Rn et 220Rn), des émetteurs gamma post émanation (214Pb, 214Bi, 212Pb), du 210Pb, 210Po et du 14C doivent être privilégiées.

In order to further assess the alterations which might underly behavioral deficits associated with a reduced dopaminergic transmission, the effects of apomorphine at doses thought to stimulate dopaminergic autoreceptors were studied on rat operant behavior.
Low doses of apomorphine caused a reward deficit when animais were shifted from continuons reinforcement to fixed ratio schedules of food delivery (fig. 1). This effect could be accounted for by a decreased ability of secondary reinforcers to sustain responding and/or by a disruption of cognitive processes (Table 1). The apomorphine-induced reward deficit in the fixed ratio 4 schedule was reversed by “disinhibitory” neuroleptics including amisulpride, pimozide, pipotiazine and sulpiride, at low to moderate doses. Conversely, “conventional” neuroleptics such as chlorpromazine, fluphenazine, haloperidol, metoclopramide and thioridazine were found inactive in reversing the deficit caused by apomorphine (fig. 2). Results obtained after lesion of dopaminergic neurons by 6-hydroxydopamine suggested that the behavioral deficit induced by apomorphine was related not so much to a reduction in dopaminergic activity in given restricted areas such as the VTA (fig. 3), the nucleus accumbens (fig. 4) or the prefrontal cortex (fig. 5), as to a functional imbalance between mesolimbic and mesocortical dopaminergic systems.
