Bone marrow/CFU-C/Macrophage CSF/Radiosensitivity Mouse bone marrow cells were plated in a semi-solid medium containing an excess amount of macro phage colony-stimulating factor (M-CSF). The stimulated macrophage colony-forming cells (CFU-M) took about 40 hours before dividing into two cells. X-Ray irradiation of the cells shortly after plating decreased the survival of CFU-M, while the quasith...

In the framework of trace element analysis by Q ICP-MS in a simulated deep Callovo-Oxfordian groundwater, separation procedures based on extraction chromatography were developed to eliminate the high salt contents and to concentrate Zr and U simultaneously. Theoretical and experimental speciation studies showed the importance of adjusting the medium to HNO₃/HF (0.5 M/0.005 M) to guarantee the s...

The present study evaluated the effects of the culturing media and the levels of nitrogen and phosphorus on the growth, biomass productivity and lipid production of four species of Microcystis (M. novacekii, M. aeruginosa, M panniformis and M. protocystis). The lipid extract was obtained by refluxing with dichloromethane (Soxhlet). The biomass and biomass productivity yields were maximized with...

Plant tolerance to salinity stress is vital for irrigation scheduling, decision-making, planning and operation, most critically, water resource management. Although there are numerous scientific data on the response of various plants stress, few studies red beet in literature, specifically under Mediterranean conditions. This study aimed investigate effects use, growth, yield parameters, thresh...

S U M M A R Y With seismic interferometry a virtual source can be created inside a medium, assuming a receiver is present at the position of the virtual source. Here we discuss a method that creates a virtual source inside a medium from reflection data, without needing a receiver inside the medium. Apart from the reflection data, an estimate of the direct arrivals is required. However, no expli...

Fluorescence is of diagnostic value for differentiating among species of aerobic pseudomonads (R. Y. Stanier, N. J. Palleroni, and M. Doudoroff, J. Gen. Microbiol. 43:159, 1966). The standard medium for detecting fluorescence is Medium B (E. 0. King, M. K. Ward, and D. E. Raney, J. Lab. Clin. Med. 44:301, 1954), which supports amino acids (J. De Ley, Ann. Rev. Microbiol. 18:17, 1964), and pepto...

We evaluated a new mycobacterial culture system, MB Redox, for recovery rate and time to detection of mycobacteria from 742 consecutive respiratory specimens and compared the results to those found with Löwenstein-Jensen (LJ) medium. Twenty specimens (2.7%) were positive for M. tuberculosis: 17 on LJ medium and 19 in MB Redox, with 16 specimens positive in both media. In addition, 24 specimens ...
