Investigation of the budding process in Tethya citrina and Tethya aurantium (Porifera, Demospongiae)
Elda Gaino Lidia Scalera Liaci Margherita Sciscioli Giuseppe Corriero 《Zoomorphology》2006,125(2):87-97
The budding process has been studied in two congeneric Mediterranean species belonging to Tethya from different sampling sites: Marsala and Venice Lagoons (Tethya citrina); Marsala Lagoon and Porto Cesareo Basin (Tethya aurantium). Buds, connected to the adult by a spiculated stalk, differ between the two species in morphology and size, since those of T. citrina are small with elongated bodies, showing only a few spicules protruding from the apical region, whereas those of T. aurantium are round, larger, and show spicules radiating from the peripheral border. In T. citrina, cells with inclusions, varying in electron density and size, represent the main cell types of the buds. In T. aurantium, the cell component shows a major diversification, resulting from spherulous cells, grey cells, vacuolar cells and peculiar micro-vesicle cells. Neither canals nor choanocyte chambers were observed in the buds of the two species. In T. citrina, bud production is similar in both sampling sites. In T. aurantium, budding occurs more rarely in Porto Cesareo Basin, probably in relation with environmental factors, such as the covering of the cortex by sediment and micro-algae. Finally, in the buds of both species, the spicule size does not differ from that of the cortex of the adult sponges, further supporting the main involvement of the cortex in organizing the skeletal architecture of the buds. 相似文献

Transverse, frontal and sagittal notochord sections of chick embryos at different developmental stages were ultrastructurally examined. The notochord tissue organization appears to be more likely to build a stiff but flexible body axis than to have an inducting role on the surrounding embryonic structures. 相似文献

Two cases of cutaneous phaeohyphomycosis by Alternaria alternata and Alternaria tenuissima 总被引:3,自引:0,他引:3

Two cases of cutaneous phaeohyphomycosis, one with a nodular appearance and the other with an erythematous infiltrating patch,
are reported in immunocompromised patients. Diagnosis was based on histological examination, which revealed hyphae and round-shaped
fungal cells in a granulomatous dermal infiltrate, and on identification of the moulds when biopsy fragments were cultured
on Sabouraud-dextrose agar without cycloheximide. The pathogens were Alternaria tenuissima in the first case and A. alternata
in the second. The fungi were examined by scanning electron microscopy. The patients were checked for bone and lung involvement
and were then treated with surgical excision and itraconazole, and itraconazole only, respectively, with clinical and mycological
resolution.

Background
Gene expression levels in a given cell can be influenced by different factors, namely pharmacological or medical treatments. The response to a given stimulus is usually different for different genes and may depend on time. One of the goals of modern molecular biology is the high-throughput identification of genes associated with a particular treatment or a biological process of interest. From methodological and computational point of view, analyzing high-dimensional time course microarray data requires very specific set of tools which are usually not included in standard software packages. Recently, the authors of this paper developed a fully Bayesian approach which allows one to identify differentially expressed genes in a 'one-sample' time-course microarray experiment, to rank them and to estimate their expression profiles. The method is based on explicit expressions for calculations and, hence, very computationally efficient. 相似文献659.
