similarity of the oral microbiota of pre-school children with that of their caregivers in a population-based study. | this study evaluated the similarity between the oral microbiota of young children and that of their adult caregivers. oral samples from children (174 dentate and 18 pre-dentate) aged 6-36 months and their caregivers in saipan were assayed using a dna probe assay. many species including streptococcus mutans, streptococcus sobrinus, actinomyces species, campylobacter rectus, fusobacterium nucleatum, prevotella intermedia, and porphyromonas gingivalis were detected in dentate and pre-dentate childr ... | 2002 | 12485330 |
saliniketals a and b, bicyclic polyketides from the marine actinomycete salinispora arenicola. | an extensive study of the secondary metabolites produced by several strains of the marine actinomycete salinispora arenicola has led to the isolation of two unusual bicyclic polyketides, saliniketals a and b (1, 2). the structures, which contain a new 1,4-dimethyl-2,8-dioxabicyclo[3.2.1]octan-3-yl ring, were assigned mainly by 2d nmr spectroscopic methods. unexpectedly, chemical derivatization of saliniketal a with mosher's acid chloride resulted in a functional group interconversion of an unsat ... | 2007 | 17253854 |
