We report the cloning and sequence analysis of a gamma-butyrolactone autoregulator regulatory island that includes an sscR gene encoding the gamma-butyrolactone autoregulator receptor from Streptomyces scabies NBRC 12914, a plant pathogenic strain. gamma-Butyrolactone autoregulators trigger secondary metabolism, and sometimes morphological differentiation(More)
To evaluate the usefulness of a novel contrast-injection protocol for high-resolution abdominal computed tomography angiography (CTA) using nitroglycerin (NTG). Abdominal CTA was performed in 80 patients using two 64-detector-row CT scanners. Forty patients were examined after administration of sublingual NTG (NTG group), while 40 were examined without NTG(More)
