Some optimal codes related to graphs invariant under the alternating group A8

In order to invent a screening system to check in vivo gene function and the efficiency of gene transfer mediated by a retroviral vector system, we established a novel packaging cell, PacNIH/A8, based on the neuropathogenic retrovirus A8-V. To construct the expression vector, pA8(Psi-), which expresses the genes gag, pol and env derived from A8-V, the SV40 early region was used for the polyaden...

We report the ionic photoproducts produced following photoexcitation of mass selected IBr(CO2)n , n50 – 14, cluster ions at 790 and 355 nm. These wavelengths provide single state excitation to two dissociative states, corresponding to the A8 P1/2 and B 2 S1/2 1 states of the IBr chromophore. Excitation of these states in IBr leads to production of I1Br and Br1I*, respectively. Potential energy ...

S100A8 and S100A9 are two calcium binding Myeloid Related Proteins, and important mediators of inflammatory diseases. They were recently introduced as partners for phagocyte NADPH oxidase regulation. However, the precise mechanism of their interaction remains elusive. We had for aim (i) to evaluate the impact of S100 proteins on NADPH oxidase activity; (ii) to characterize molecular interaction...

Amphipols (APols) are short amphipathic polymers that can substitute for detergents to keep membrane proteins (MPs) water-soluble while stabilizing them biochemically. We have examined the factors that determine the size and dispersity of MP/APol complexes and studied the dynamics of the association, taking as a model system the transmembrane domain of Escherichia coli outer membrane protein A ...

Amphipols are short amphilic polymers designed for applications in membrane biochemistry and biophysics and used, in particular, to stabilize membrane proteins in aqueous solutions. Amphipol A8-35 was obtained by modification of a short-chain parent polymer (poly(acrylic acid); PAA) with octyl- and isopropylamine, to yield an amphiphilic product with an average molar mass of 9-10 kg x mol(-1) (...

A substantial proportion of contemporary migration flows to the UK are made by nationals from countries which have recently joined the EU. The nature of A8 migration during the recession is examined in this paper, mainly using data from the Worker Registration Scheme. The recession has seen a decline in new A8 migrants entering the UK labour market, but the decline has been sectorally uneven, w...
