    Structure of the DNA Octanucleotide d(ACGTACGT)2 (1996)

    Notes: d(ACGTACGT), C78H84N30O32P7.20H2O, Mr (DNA) = 2170, tetragonal, P43212 (No 96), a = 42.845 (1), b = 42.845(1), c = 24.804 (1) Å, V = 45532.5 (2) Å3, z = 8,λ(MoKα) = 0.71069 Å,µ(MoKα) = 0.10 mm−1, T = 295 K, R = 0.18 for 1994 unique reflections between 5.0 and 1.9 Å resolution. The self-complementary octanucleotide d(ACGTACGT)2 has been crystallized and its structure determined to a resolution of 1.9 Å. The asymmetric unit consists of a single strand of octamer with 20 water molecules. It is only the second example of an octanucleotide having terminal A·T base pairs whose structure has been determined by X-ray crystallography. The sequence adopts the modified A-type conformation found for all octanucleotide duplexes studied to date with the helix bent by approximately 15° and an average tilt angle of 0°. Unusually the data collection was carried out using a 3 kW molybdenum sealed-tube source. The conformational details are discussed in comparison with other closely related sequences.

    Quantitative radionuclide angiocardiography for left-to-right cardiac shunts in children (1982)
    Springer
    Pediatric cardiology 3 (1982), S. 1-5 
    Details
    ISSN: 1432-1971

    Notes: Summary Pulmonary to systemic flow ratios (Qp/Qs) were estimated by quantitative radionuclide angiocardiography (QRAC) in 135 children. The Qp/Qs ratios were derived from pulmonary time/activity curves using a gamma variate model. Eighty-five of these children also had Qp/Qs ratios estimated by oximetry at cardiac catheterization. Left-to-right shunts with a Qp/Qs range of 1.2 to 3.0 were detected and quantitated by radionuclide angiography with an accuracy similar to that for oximetry. The correlation between Qp/Qs, determined by QRAC and by oximetry was good (r=.93; SEE .31). This relatively noninvasive technique has now been used to estimate the Qp/Qs ratio in 34 children with a clinically suspected left-to-right shunt, and postoperatively in 16 cases with residual murmurs; it has obviated the need for catheterization in many of these patients. The technique may also be used serially to determine changes in the Qp/Qs ratio in patients with known left-to-right shunts.

    Cyanobacteria carrying ansmt-lux transcriptional fusion as biosensors for the detection of heavy metal cations (1996)

    Notes: Abstract The metal-responsivesmt operator/promoter region ofSynechococcus PCC7942 was fused to theluxCDABE genes ofVibrio fischeri. Plasmid DNA (pJLE23) carrying this fusion conferred metal ion-inducible luminescence to transformed cyanobacteria.Synechococcus PCC7942 (pJLE23) was sensitive to ZnCl2 concentrations within a range of 0.5–4 μM as demonstrated by induction of luminescence. Trace levels of CuSO4, and CdCl2 were also detected.
