The immunocytochemical study of the bovine placenta has demonstrated the presence of cells containing alphamelanotropic hormones, in the decidual epithelium, since the 4th month of pregnancy. The number and the staining intensity of those cells grow up with the placental development. Since the 6th month, we observed the immunoreactional presence of cells in the foetal chorionic epithelium. [less ▲]

L’organe de l’audition chez les mammifères est sans doute l’une des plus remarquables structures rencontrées chez les vertébrés supérieurs. Cet organe, qui porte le nom de celui qui l’a décrit pour la première fois à la moitié du XIXème siècle (Alfonso Corti, 1851), possède un arrangement cellulaire complexe et hautement ordonné. L’organe de Corti est situé sur la face dorsale du canal cochléaire, au sein de l’oreille interne. Il est composé de cellules sensorielles reposant sur des cellules de soutien. Trois rangées de cellules sensorielles externes et une rangée de cellules sensorielles internes sont réparties de part et d’autre du tunnel de Corti, lui-même limité par les cellules piliers externes et internes. Chaque cellule sensorielle est séparée de la suivante par une cellule de soutien, les cellules de Deiters du côté externe et les cellules phalangeaires du côté interne. À l’état mature, cette structure est bien connue ; cependant, notre connaissance de la mise en place du cytosquelette dans ces différentes cellules hautement spécialisées de l’organe de l’audition en développement reste largement parcellaire et incomplète. Dans ce mémoire, nous avons analysé en microscopie confocale à balayage laser le développement de l’organe de Corti entre le 18e jour embryonnaire et le 15e jour post-natal. Pour appréhender le cytosquelette, nous avons utilisé les anticorps anti-tubuline βIV, anti-vimentine, anti-cytokératine pan (CK 1, 4, 5, 6, 8, 10, 13, 18 et 19), et anti-cytokératine 8. Seule la partie basale du canal cochléaire et les structures adjacentes ont été examinées. Nous observons que la tubuline βIV est présente au niveau des cellules sensorielles internes entre E21 et P4-P5, au niveau des cellules sensorielles externes entre P0 et P4-P5, de la cellule phalangeaire à P0, au niveau de la cellule pilier interne et au niveau des cellules de Deiters entre P0 et P15 et enfin au niveau de la cellule pilier externe entre P4-P5 et P15 ; ainsi, cette protéine est d’abord présente dans les cellules sensorielles et ensuite dans les cellules de soutien. Enfin, nous montrons pour la première fois que la cellule phalangeaire est marquée à P0 avec cet anticorps. Nous décelons également une positivité dans toutes les cellules épithéliales du canal cochléaire, et en particulier au niveau des cellules piliers et au niveau des cellules de Deiters entre P8 et P12, avec les deux anticorps anti-cytokératine utilisés. Nous localisons de la vimentine au sein de l’épithélium du canal cochléaire alors que celle-ci est typique des cellules d’origine mésodermique. Cette transition épithélio-mésenchymateuse permettrait aux cellules épithéliales d’acquérir une plus grande liberté de mouvement. Finalement, nous suggérons que les marquages préférentiels des cellules piliers et des cellules de Deiters entre P8 et P12 obtenus avec les quatre anticorps étudiés pourraient être corrélés avec la formation du tunnel de Corti et des espaces de Nuel dans l’organe de l’audition.

Human pituitary adenomas were fixed in glutaraldehyde and embedded in epon. Ultrathin sections were incubated either with anti-hGH, anti-hPRL or anti-hLH. They were incubated with second step goat anti-rabbit immunoglobulins linked to gold particles. Two PRL secreting adenomas, one GH and PRL secreting adenoma, one ACTH secreting adenoma and two non secreting adenomas were studied. The specificity and the limits of the method were discussed in relation with the results obtained in light microscopy with the PAP method. [less ▲]

The report first analyses the causes and consequences of the recent de-urbanisation of industrial activities. On account of the problems created by this movement, the survey then puts forward new solutions that aim for a better integration of industrial concerns. These proposals deal mainly with the types of industries that should be maintained or established as well as the terms and conditions of integration. In this connection, it seems impera¬tive to work out a new planning policy for urban space where the renovated secondary sector would find its place due to new formulas such as vertical industrial structures, individual buildings with an urbanised facade and small industrial estates.

In adult male and female Japanese quail, aromatase-immunoreactive cells were identified in the spinal dorsal horns from the upper cervical segments to the lower caudal area. These immunoreactive cells are located mostly in laminae I-III, with additional sparse cells being present in the medial part of lamina V and, at the cervical level exclusively, in lamina X around the central canal. Radioenzyme assays based on the measurement of tritiated water release confirmed the presence of substantial levels of aromatase activity throughout the rostrocaudal extent of the spinal cord. Contrary to what is observed in the brain, this enzyme activity and the number of aromatase-immunoreactive cells in five representative segments of the spinal cord are not different in sexually mature males or females and are not influenced in males by castration with or without testosterone treatment. The aromatase activity and the numbers of aromatase-immunoreactive cells per section are higher at the brachial and thoracic levels than in the cervical and lumbar segments. These experiments demonstrate for the first time the presence of local estrogen production in the spinal cord of a higher vertebrate. This production was localized in the sensory fields of the dorsal horn, where estrogen receptors have been identified previously in several avian and mammalian species, suggesting an implication of aromatase in the modulation of sensory (particularly nociceptive) processes.

This paper reports on investigations to speed up time domain simulations of large electric power systems. First, a decomposed scheme is considered which exploits the bordered block diagonal structure of the original Jacobian involved in the Newton iterations, and keeps the resulting “local” Jacobians constant over multiple iterations. Next, a localization technique is considered, allowing to perform less iterations on the system components with lower activity. Finally, a third scheme consists of visiting only a subset of components, identified as active, and skipping the other ones, identified as latent. The first two techniques solve the whole set of equations with the required accuracy, while the third one involves an adjustable degree of approximation. The methods are illustrated on a small system, while preliminary checks of computational savings from a large test system are reported. Additional results deal with the application of the localization and latency techniques to simplified simulation of the detailed model. [less ▲]
