As a first step toward developing the methodology for screening large numbers of heterocyst-forming freshwater cyanobacteria strains for the presence of various types of nitrogenases and hydrogenases, we surveyed the distribution of these genes and their activities in 14 strains from culture collections. The nitrogenase genes include nif1 encoding a Mo-type(More)
The antibacterial activity of DQ-113, formerly D61-1113, was compared with those of antibacterial agents currently available. MICs at which 90% of the isolates tested are inhibited (MIC90s) of DQ-113 against clinical isolates of methicillin-susceptible and -resistant Staphylococcus aureus and methicillin-susceptible and -resistant coagulase-negative(More)
Unsaturated transition metal carbonyls are important in processes such as organometallic synthesis, homogeneous catalysis, and photochemical decomposition of organometallics. In particular, a metal monocarbonyl offers a zeroth-order model for interpreting the chemisorption of a CO molecule on a metal surface in catalytic activation processes. Quite large(More)
It is well documented that most cortical interneurons originate from the basal forebrain and migrate tangentially to the cortex. However, relatively little is known about their migration after their arrival at the cortex. To elucidate the route and mode of intracortical migration of the interneurons, we performed real-time analysis by utilizing glutamate(More)
The millimeter- and submillimeter-wave spectra of the NiBr radical in the X (2)Pi(3/2) and A (2)Delta(5/2) states were observed by a source-modulated microwave spectrometer. The NiBr radical was generated in a dc glow discharge through the mixture of Br(2) vapor and Ar gas by the sputtering reaction with a Ni cathode. Observed transition frequencies were(More)
