    Energy shift in (dtμ)e due to the finite size of the muonic molecular ion (dtμ)+ (1992)

    Notizen: Abstract The energy shift due to the presence of the extended (dtμ)11 pseudonucleus (in its first excited state with one unit of angular momentum) in the quasihydrogenlike system (dtμ)11 e 1s is estimated using perturbation theory up to second order with two choices of zeroth order electron wavefunctions. The energy shift is found to be 0.50 meV using pure Coulomb electron wavefunctions and 0.58 meV using electron wavefunctions calculated with a potential modified to take partial account of the finite size of (dtμ)11. In both cases, the perturbation Hamiltonian is expanded in multipoles, retaining terms up to and including octupole terms.

    In vitro regulation of neutrophil migration by β2 integrins (LFA-1 and Mac-1) in patients with otitis media (1997)

    Notizen: Abstract β2 integrins are located on the surface of neutrophils and have important roles in cell migration to an inflammatory site. We investigated the inhibitory effect of antibodies to the β2 integrin family for neutrophil migration into middle ear effusion (MEE) during acute otitis media in children and chronic otitis media with effusion in both children and adults. Neutrophil migration to MEE samples was assessed in vitro in a 48-well Boyden chamber. The migration index value and the activity of chemo-attractants in MEE was found to be proportional to the number of infiltrated cells. Migration of activated neutrophils into MEE was significantly inhibited by blocking surface-expressed cell adhesion molecules (CAM) with anti-CD11b (Mac-1α) and anti-CD18 (common β2 subunit) antibodies (P 〈 0.001) but not with anti-CD11a (LFA-1α) antibody. These inhibitory effects of anti-CAM antibodies were found in all types of MEE in all age groups studied. A new therapeutic approach to inflammation has been considered recently that utilizes inhibition of neutrophil migration with a blocking antibody to CAM. Our in vitro data support a possible therapeutic effect of anti-CAM antibody, indicating that administration of anti-CD11b and CD18 antibodies may be useful for treating human otitis media.
