Placental chorioangioma is a benign vascular tumor. Lesions larger than 4cm may cause fetal and maternal complications. Its association with disseminated neonatal hemangiomatosis is rarely described. We report a case of a large chorioangioma associated with an hydrops foetalis and disseminated neonatal hemangiomatosis. The relationship between placental chorioangioma and hemangioma is briefly discussed. [less ▲]

We consider the problem of performing N − k security analyses in large scale power systems. In such a context, the number of potentially dangerous N − k contingencies may become rapidly very large when k grows, and so running a security analysis for each one of them is often intractable. We assume in this paper that the number of dangerous N − k contingencies is very small with respect to the number of non-dangerous ones. Under this assumption, we suggest to use importance sampling techniques for identifying rare events in combinatorial search spaces. With such techniques, it is possible to identify dangerous contingencies by running security analyses for only a small number of events. A procedure relying on these techniques is proposed in this work for steady-state security analyses. This procedure has been evaluated on the IEEE 118 bus test system. The results show that it is indeed able to efficiently identify among a large set of contingencies some of the rare ones which are dangerous. [less ▲]

Cell interactions with the extracellular matrix are consistently modified in neoplasia. Malignant transformation has been correlated with modifications in the synthesis and distribution of matrix components and with alterations of cell adhesive properties to these components. A particular class of genes, able to suppress the transformed phenotype in normal cells, may be involved in those phenotypic changes. By studying somatic cell hybrids between mouse hepatoma (BWTG3) cells and normal rat skin fibroblasts (RSF), Islam and co-workers were able to localize a gene or a group of genes controlling anchorage dependence and cell growth in vitro. This (or these) gene(s) was (were) assigned to the q22-23 fragment of rat chromosome 5. In the present study, we compare the morphology and the interactions with the extracellular matrix proteins (laminin, fibronectin, and collagen IV) and the synthesis of these proteins by RSF X BWTG3 hybrid cells that had either retained (BS181p10) or lost (BS181a5) the q22-23 region of rat chromosome 5. Our results suggest that the rat 5q22-23 fragment controls a part of the cell differentiation program including morphology, attachment to extracellular matrix, and synthesis of some matrix proteins, particularly alpha 1 and alpha 2 chains of collagen IV.

Connexins, the structural components of gap junctions, control cell growth and differentiation and are believed to belong to a family of tumour suppressor genes. Studies on connexin localization in brain showed that several of these proteins were expressed in distinct compartments of the brain in a cell-type specific manner, indicating that different gap junctions play specific roles in the physiology of the mammalian brain. In this report, we first cloned rat connexin-30 cDNA from brain and showed that it was expressed in long-term primary culture of rat astrocytes. In order to examine the potential role of connexin-30 in tumour cell proliferation, we transfected the connexin-30 cDNA into two rat glioma cell lines (9L and C6) which have lost its expression. Transfected clones adequately expressed membrane-bound connexin-30 protein. Connexin-30-expressing clones showed slower growth, lower DNA synthesis and reduced proliferation in soft agar as compared with the parental and control cells. We concluded that connexin-30 may also probably be considered as a tumour suppressor in rat gliomas. [less ▲]

Context: The CoRoT satellite searches for planets by applying the transit method, monitoring up to 12 000 stars in the galactic plane for 150 days in each observing run. This search is contaminated by a large fraction of false positives, caused by different eclipsing binary configurations that might be confused with a transiting planet. <BR />Aims: We evaluate the rates and nature of false positives in the CoRoT exoplanets search and compare our results with semiempirical predictions. <BR />Methods: We consider the detected binary and planet candidates in the first three extended CoRoT runs, and classify the results of the follow-up observations completed to verify their planetary nature. We group the follow-up results into undiluted binaries, diluted binaries, and planets and compare their abundances with predictions from the literature. <BR />Results: 83% of the initial detections are classified as false positives using only the CoRoT light-curves, the remaining 17% require follow-up observations. Finally, 12% of the candidates in the follow-up program are planets. The shape of the overall distribution of the false positive rate follows previous predictions, except for candidates with transit depths below about 0.4%. For candidates with transit depths in the range from 0.1-0.4%, CoRoT detections are nearly complete, and this difference from predictions is probably real and dominated by a lower than expected abundance of diluted eclipsing binaries. The CoRoT space mission, launched on December 27th 2006, has been developed and is operated by CNES, with the contribution of Austria, Belgium, Brazil , ESA (RSSD and Science Programme), Germany and Spain.
