Ornithine-oxo-acid aminotransferase (EC 2.6.1.13) from rat kidney was prepared as a single homogeneous protein as judged by polyacrylamide gel electrophoresis, ultracentrifuge analysis and double diffusion precipitin test. Content of pyridoxal phosphate, light absorption spectra, circular dicroism spectra, Km values, inhibitors, and electrophoretic(More)
A new antitumor antibiotic, fredericamycin A (FCRC-A48, NSC-305263), has been isolated from a strain of Streptomyces griseus (FCRC-48). Based on its unique ultraviolet-visible spectrum, infrared spectrum, proton and carbon-13 nuclear magnetic resonance spectra and mass spectra, it is judged to be a novel acid-base indicator type of compound. Its production,(More)
BACKGROUND The study was aimed to evaluate the microleakage of Biodentine using two different manipulation methods by dye penetration. MATERIALS AND METHODS A total of 60 single-rooted human maxillary permanent teeth were cleaned and obturated with gutta-percha using lateral condensation method. Standardized root-end cavities were prepared after apical(More)
The Enterococcus flora of duck intestines consisted of E faecalis and E faecium in ducklings less than eight weeks old and E faecalis, E faecium and E gallinarum in ducks more than eight weeks old. The enterococci were resistant to several antibiotics; chloramphenicol and gentamycin sulphate were the only antibiotics of those tested which were moderately(More)
BACKGROUND Dental caries is a multifactorial disease, causes of which are mostly understood nowadays. This disease is not only treatable but also preventable, if detected in its initial stage. In a developing country like India, facility of dental treatment is available mostly for urban population, whereas a very common approach of dental disease treatment(More)
Isolation of a pentaene macrolide antibiotic (NSC-277813) from Streptomyces griseus (FCRC-21) fermentation broth is described. Using field desorption mass spectrometry and high resolution field desorption mass spectrometry on the intact and derivatized antibiotic and degradation products, the antibiotic was identified as fungichromin. The application of(More)
