The first hydrothermal synthesis of an Al-rich alluaudite-type compound, namely disodium dimanganese aluminium tris(phosphate), which has been obtained at 1073 K and 0.1 GPa starting from the composition Na2Mn2Al(PO4)(3), is reported. The crystal structure, which has been refined in the monoclinic C2/c space group, is identical to that of natural alluaudite. The structure consists of kinked chains of edge-sharing M1 and M2 octahedra, which contain Mn2+ and Al3+ ions. The chains are stacked parallel to {101} and are connected in the b direction by the P1 and P2 tetrahedra. These interconnected chains produce channels parallel to c, which contain the large A1 and AT sites occupied by Na+ and Mn2+ ions. [less ▲]

The embryonic pronephric kidneys of Xenopus and zebrafish serve as models to study vertebrate nephrogenesis. Recently, multiple subdomains within the Xenopus pronephros have been defined based on the expression of several transport proteins. In contrast, very few studies on the expression of renal transporters have been conducted in zebrafish. We have recently shown that the anterior and posterior segments of the zebrafish pronephric duct may correspond to the proximal tubule and distal tubule/duct compartments of the Xenopus and higher vertebrate pronephros, respectively. Here, we report the embryonic expression pattern of the Na(+)/PO(4) cotransporter SLC20A1 (PiT1/Glvr-1) gene encoding a type III sodium-dependent phosphate cotransporter in Xenopus and zebrafish. In Xenopus, SLC20A1 mRNA is expressed in the somitic mesoderm and lower level of expression is detected in the neural tube, eye, and neural crest cells. From stage 25, SLC20A1 is also detectable in the developing pronephros where expression is restricted to the late portion of the distal pronephric tubules. In zebrafish, SLC20A1 is transcribed from mid-somitogenesis in the anterior part of the pronephros where its expression corresponds to the rostral portion of the expression of other proximal tubule-specific markers. Outside the pronephros, lower level of SLC20A1 expression is also observed in the posterior cardinal and caudal veins. Based on the SLC20A1 expression domain and that of other transporters, four segments have been defined within the zebrafish pronephros. Together, our data reveal that the zebrafish and Xenopus pronephros have non-identical proximo-distal organizations. [less ▲]

In this article, the authors describe how transhumanist ideas influence science nanotechnology policy in the United States. Subsequently, they distinguish different ways in which policymakers and scientists, both in the US and in Europe, address social and ethical implications of nanotechnology research and development. They discern two dominant approaches to responsible technology development: a rationalist approach, which separates scientific issues from ethical questions, and a procedural approach, which adheres to guiding moral principles for responsible technology development. They add to this classification an experimental approach, which directly intervenes in scientific practice. By indicating how concerned actors ethicize nanotechnology in different ways, the authors seek to clarify what is meant by ethics in nanotechnology development and incite reflection on the interconnectedness of ethics and new technologies.

The growth of three wood inhabiting basidiomycetes (Microporus xanthopus, Pycnoporus sanguineus and Schizophyllum commune) isolated from a tropical coastal forest of Papua New Guinea is characterized in relation to temperature and NaCl salinity. P. sanguineus and M. xanthopus present a very similar response to NaCl salinity, but P. sanguineus has a wider tolerance for temperature variations. S. commune withstands wide temperature variations, but it is the only one to present a marked salt resistance. This correlates with its abundance along the sea. The presence of P. sanguineus in the same habitat is rather unexpected since it is very sensitive to NaCl salinity. Its high growth rate probably allows it to take advantage of periods of high rains that limit salt accumulation. [less ▲]

Humans have always and everywhere made or done something on or with « nature ». But the questions aren’t the same everywhere and consequently the resulting decision-making process may follow entirely divergent paths. The undertakings of introduced or re-introduced species have multiplied though their success has never been guaranteed. Examining these undertakings closely, we discover that they are as much combinations of people’s recipes, technoscience formulas as well as those surprises that living beings have always been full of. In this paper, we support this idea by following trajectories of the European rabbit (Oryctolagus cuniculus) towards Australia or new-Zealand. We study the many ways these have crossed other ways of starting a relationship with non-humans on the one hand, and applied ecology on the other hand, which had just been discovered at the beginning of the 20th century. Several controversies have followed one after another since then. These can be described as crises or moments to blot out. For us, these controversies essentially represent ways of revealing a reestablishment of order. There are no clear categories and no obvious balance in these case histories. Only living beings which meet, transform, overlap and shirk each other. [less ▲]

The influence of growth hormone and insulin-like growth factor I on human melanocytes is being increasingly recognized. Clinical evidence has shown that when recombinant human growth hormone (hGH) is administered to children of short stature, the growth of melanocytic naevi is boosted. This study was conducted on 56 hGH-triggered naevi and nine similar lesions excised before or after hGH therapy for hypopituitarism and Turner's syndrome. A series of 40 naevi excised from age-matched healthy children served as controls. Atypicality of naevocytes was investigated using image analysis, AgNOR counts, immunohistochemistry (HMB-45, NKI-C3, Ki-67, anti-bcl-2-oncoprotein), and DNA flow cytometry. The data associate hGH treatment with anisokaryosis and increased AgNOR and Ki-67 counts in naevocytes. The same cells also show abnormal patterns of HMB-45 immunolabelling. These indications of naevocyte activation were not suggestive of malignant transformation. hGH-triggered melanocytomas should be added to the list of atypical melanocytic naevi. The long-term evolution of these lesions remains unknown and the potential risk of malignant transformation awaits careful evaluation. [less ▲]

Le naevus spilus est défini par la présence d’un semis de petits naevi mélanocytaires dispersés sur une plaque lentigineuse. Il touche environ 2,3% de la population et apparaît habituellement au cours de l’enfance. Les lésions mesurant entre 1 à 4 cm sont les plus courantes, mais différents sous-types peuvent être distingués selon l’âge d’apparition et la dimension de la lésion. Deux cas exceptionnels de naevus spilus géant, dont un de survenue tardive, sont présentés. Qouique le naevus spilus habituel de petite taille soit consideré comme une lésion pigmentaire bénigne, le caractère congénital et le diamètre supérieur à 4 cm sont reconnus comme des facteurs de risque pour le développement d’un mélanome. Une surveillance clinique et dermoscopique du naevus spilus géant est recommendée. [less ▲]
