Eighty-six strains of the 10 major agglutination types of Vibrio anguillarum (serovars O1 to O10) and 6 nontypeable strains of V. anguillarum have been characterized by ribotyping with a probe complementary to 16S and 23S rRNA of Escherichia coli and by plasmid profile analysis. Forty-four different ribotypes were observed with the restriction enzyme HindIII. Ribotype similarity was compared by...

In Aerobacter aerogenes, the mutational event permitting the utilization of d-arabinose as a source of carbon and energy is a regulatory mutation resulting in the constitutive synthesis of certain enzymes of the l-fucose catabolic pathway. l-Fucose isomerase catalyzes the isomerization of d-arabinose to d-ribulose. This enzyme was purified to homogeneity as indicated by a single band in disc-ge...

Compound 2-chloro-5-nitrophenol (2C5NP) is a typical chlorinated nitroaromatic pollutant. To date, the bacteria with the ability to degrade 2C5NP are rare, and the molecular mechanism of 2C5NP degradation remains unknown. In this study, Cupriavidus sp. strain CNP-8 utilizing 2-chloro-5-nitrophenol (2C5NP) and meta-nitrophenol (MNP) via partial reductive pathways was isolated from pesticide-cont...

V. Parpura and P.G. Haydon (eds.), Astrocytes in (Patho)Physiology of the Nervous System, 1 DOI: 10.1007/978-0-387-79492-1_1, © Springer Science + Business Media, LLC 2009 The history of the morphology and electrophysiology of the neuroglia , which was the historical term used for what are now termed astroglia or astrocytes, is briefly reviewed. The interpretation of these data around 1970 was ...

The statistical NLP and IR literatures tend to make a “homogeneity assumption” about the distribution of terms, either by adopting a “bag of words” model, or in their treatment of function words. In this paper we develop a notion of homogeneity detection to a level of statistical significance, and conduct a series of experiments on different datasets, to show that the homogeneity assumption doe...

Molecular characterization of one stable strain of Trypanosoma cruzi, the 21 SF, representative of the pattern of strains isolated from the endemic area of São Felipe, State of Bahia, Brazil, maintained for 15 years in laboratory by serial passages in mice and classified as biodeme Type II and zymodeme 2 has been investigated. The kinetoplast DNA (kDNA) of parental strain, 5 clones and 14 subcl...

In this study, Ti-48Al-3Nb-1.5Ta powders were manufactured from cast bars by the supreme-speed plasma rotating electrode process (SS-PREP) and used to prepare hot isostatically pressed (HIPed) material at 1050–1260 °C with 150 MPa for 4 h. The phase, microstructure mechanical performance analyzed XRD, SEM, electrical universal testing machine other methods. results revealed that phase constitut...
