Microfabricated silicon gratings provide unique test procedures for instruments in neutron scattering and the interpretation of experimental data. Ultra-Small Angle Neutron Scattering (USANS) is currently becoming an effective technique for the analysis of structures in the micrometer range. A series of one-dimensional silicon gratings was fabricated using a highly anisotropic ion etching techn...

Monovalent Fab fragments from immunoglobulins, directed against Escherichia coli small ribosomal subunit proteins, were tested for their effect on poly(U)-directed synthesis of polyphenylalanine by rat liver ribosomes. Of the 18 Fabs tested, 3, anti-S10, anti-S12, and anti-S14, inhibited polyphenylalanine synthesis; antibodies against 3 of the 21 E. coli ribosomal proteins (S1, S16, and S17) we...

The complete nucleotide sequences of the 5.8S and 26S rRNA genes of Physarum polycephalum and the transcribed spacer between them were determined. Comparison of the sequences with those of the Escherichia coli 23S rRNA and yeast 26S rRNA genes showed that there are 16 highly homologous regions in the sequences of Physarum and E. coli and that eukaryotes have some eukaryote-specific extra sequen...

We wish to make the following correction to the published paper [1].[...].

Legionella bozemanae is a rare isolate in clinical specimens. We describe a case of joint infection due to L. bozemanae in an immunocompromised patient with dermatomyositis. Without the use of PCR screening or culture on specialized medium, the organism would not have been detected.

The presence of a multicopy chromosome, with each copy containing two rRNA operons (rrnA and rrnB), has been an obstacle to analysing mutated rRNA in Synechococcus PCC 7942. To create a system for expressing homogeneous mutated rRNA, the chromosomal rrn operons were sequentially inactivated and a final strain was successfully obtained with all the chromosomal rrn operons inactivated but carryin...

background:  aeromonas spp. can cause diarrhea and various infections in humans. access to rapid techniques with a high sensitivity and specificity is strongly needed for the identification of aeromonas species. the aim of this study was to evaluate two different methods including api 20e bacterial identification tests and the molecular detection using pcr primers specific for 16s-rrna and 23s-...
