Allele frequencies for 19 autosomal STRs (F13A01, FESFPS, F13B, LPL, D5S818, D7S820, THO1, TPOX, VWA31, CSF1P0, D16S539, D13S317, D3S1358, D8S1179, FGA, PENTA D, PENTA E, D21S11, D18S51) were estimated from a sample between 364 and 400 unrelated individuals living in the northern department of Antioquia.
Using mutagens on sperm and spermatids we have produced nineteen chromosomal inversions in mice. The levels of radiation and chemical mutagen we used induced inversions in about one per cent of the animals screened. Nine inversions have been transmitted through successive generations, and the particular frequency of first meiotic anaphase bridges manifested by each inversion remained constant. ...
More and more integration systems use ontologies to solve the problem of semantic heterogeneities between autonomous databases. To automate the integration process, a number of these systems suppose the existence of a shared domain ontology a priori referenced by the local ontologies embedded in the various sources. When the shared ontology evolves over the time, the evolution may concern (i) t...
In this paper, (1) we describe our ongoing work aimed at improving the Eighteenth-Century Collections Online (ECCO) database’s utility as a comprehensive and high-fidelity resource, and (2) we discuss some preliminary experiments based on ECCO.
more catalogues than it was considered possible to list). Entries in the main section of the book are organized by manufacturer's name. In some but not all cases dates of foundation or incorporation and known addresses are provided, as well as bibliographical details of literature produced. A subsidiary listing of the libraries and collections consulted gives the names of manufacturers whose pu...
To evaluate the population genetic diversity of the ovate pompano, we isolated and characterized 19 microsatellite markers using a (CA)13-enriched genomic library. Polymorphism was assessed in 30 individuals from a single population collected from the Daya Bay Aquaculture Center, Guangdong, China. The number of alleles per locus ranged from 2 to 18 with an average of 7.8. The observed and expec...
Cystic fibrosis is the most common autosomal recessive hereditary disease in white populations. It characterized by formation of abnormal secretions exocrine glands located sweat and salivary glands, tracheobronchial tree, large intestine, pancreas. The severity clinic depends on type "cystic transmembrane regulatory protein" gene mutation. Although cases are diagnosed infancy or childhood, som...
