Hemadsorbing (HA+) virulent Mycoplasma pneumoniae and spontaneously derived nonhemadsorbing (HA-) avirulent mutants were compared by biochemical and ultrastructural techniques in an attempt to understand the molecular basis for cytadsorption. Lactoperoxidase-catalyzed iodination of intact mycoplasmas indicated that both virulent and avirulent mycoplasmas displayed similar surface protein patter...

Oscillator strengths for the three lowest ground-state transitions 3p S0-3p 4s P1, 3p 6 S0-3p 4s P1, and 3p 6 S0-3p 3d P1 in argonlike K II are reported. The values were determined by lifetime measurements made using foil excitation of a fast ion beam, which yielded values t(4s P1)58.461.6 ns, t(3d P1)52.460.4 ns, and t(4s P1)50.4360.04 ns. Application of these results to the development of ext...

DEFINITION: Given a set of points p1, p2, ......., pn, the skyline query returns a set of points P, called as the skyline points, such that any point pi ∈ P is not dominated by any other point in the dataset. A point p1 dominates another point p2, if p1 is not worse than p2 in all dimensions and p1 is better than p2 in at least one dimension. In other words, a point p1 dominates another point p...

Transduction frequency with phage P1 had been observed to be very low in Escherichia coli K-12 mutants lacking the operon (ppk1-ppx) responsible for the synthesis of inorganic polyphosphate (poly P). We now find that these mutants, for lack of poly P, are lysogenic for P1 and when infected with phage P1 produce only approximately 1% the number of infective centers compared with the WT host. Bot...

The C terminus of the major surface protein P1 from Streptococcus mutans is composed of a hydrophilic domain, an LPNTGV motif, a hydrophobic domain, and a charged tail. These features are shared by surface proteins from many gram-positive coccal bacteria. To investigate the role of the C-terminal domains in antigen P1 surface localization, full-length and truncated P1 gene constructs, which wer...

The study of factorization in the linearized gravity is extended to the graviton scattering processes with a massive scalar particle, with a massless vector boson and also with a graviton. Every transition amplitude is shown to be completely factorized and the physical implications of their common factors are discussed.

BACKGROUND Vascular adhesion protein-1 (VAP-1) is an adhesion molecule that plays a key role in recruiting leucocytes into sites of inflammation. We have previously shown that 68Gallium-labelled VAP-1-targeting peptide (68Ga-DOTAVAP-P1) is a positron emission tomography (PET) imaging agent, capable of visualising inflammation in rats, but disadvantaged by its short metabolic half-life and rapid...

An additive hereditary graph property is a class of simple graphs which is closed under unions, subgraphs and isomorphisms. If P1, . . . ,Pn are graph properties, then a (P1, . . . ,Pn)-decomposition of a graph G is a partition E1, . . . , En of E(G) such that G[Ei], the subgraph of G induced by Ei, is in Pi, for i = 1, . . . , n. The sum of the properties P1, . . . ,Pn is the property P1 ⊕ · ·...
