Abstract: Systems, methods, and computer program products for generating an enhanced set of sequences for taxonomical classification are disclosed. In various embodiments, a plurality of reference sequences are received. Each of the plurality of reference sequences corresponds to a taxonomical classification. A label corresponding to at least one of the reference sequences is assigned to each of a plurality of supplemental sequences. Each of the plurality of supplemental sequences and each of the plurality of reference sequences are truncated to a region of interest to thereby generate a truncated set of sequences. Similarity is measured between pairs of truncated sequences in the truncated set of sequences to determine whether the similarity is above a predetermined threshold. An intermediate taxonomical label is assigned to the pair of truncated sequences in the truncated set of sequences when the similarity is above the predetermined threshold to thereby generate an enhanced set of sequences.

Abstract: An isolated bacterium of the genus Helicobacter, characterized by the 16S ribosomal RNA encoding nucleotide sequence defined in the Sequence Listing as SEQ ID NO:1 is provided. An isolated nucleic acid having the nucleotide sequence defined in the Sequence Listing as SEQ ID NO:1 is provided. Such a nucleic acid can be used for diagnosis of infection with H. hepaticus. A nucleic acid of the present invention in a vector suitable for expression of the nucleic acid is also provided. The vector can be in a host suitable for expressing the nucleic acid. A purified antigen specific for H. hepaticus is provided. A method of making an animal model for chronic Helicobacter infection is also provided.

Abstract: Novel substituted 2-(arylmethoxy)phenol compounds having the structural formula: ##STR1## where X is selected from the group consisting of: (a) napthyl, pyridyl, quinolyl and 2-benzimidazolyl; and(b) a substituted alkyl or alkoxy phenyl.

Abstract: A premixed, dental-cement composition, which cement composition comprises a chelate of a metal and hydroxybenzophenone, particularly a zinc hydroxybenzophenone chelate; a filler material, particularly a metal oxide and preferably a metal oxide which is the same as that of the metal hydroxybenzophenone chelate; and a modifier, which dental-cement composition may be heated reversibly between a solid and a liquid state, is premixed and exhibits reduced irritation and solubility over the ordinary dental cements of the prior art.
