- Systematic multiconfiguration Hartree-Fock results are presented for the transition probabilities and excited-state lifetimes in the term system of the boron atom. Particularly, the interaction between the 1s(2)2s2p2 configuration and the 1s(2)2s2ns2S and 1s(2)2s2nd2D Rydberg series is considered. Term energies and transition-matrix elements are calculated to convergence using increasing active sets of s, p, d, f, and g orbitals.

- Hyperfine structure constants for the ground and first excited states of sodium are calculated using a newly written hyperfine structure program, which is part of the MCHF Atomic Structure Package. The calculated hyperfine structure constants are compared with the most reliable values obtained in other theoretical studies and in experiments. Also, a new accurate experimental determination of the 3p P-2(1/2) state hyperfine structure is presented.

Mchf Calculations For Atomic Properties

Tidskriftsartikel (refereegranskat)abstract
- A historical review of the early development of Hartree-Fock and Multiconfiguration Hartree-Fock theories is presented. After the underlying theory is summarized, some recent results from the application of these methods to the prediction of atomic properties are described. These include total energies, transition probabilities, autoionization rates, specific mass shifts, and hyperfine parameters. In each case, large-scale, systematic procedures are used to show the convergence of the theoretically predicted results.

- The effect in vivo of G-CSF on neutrophil and eosinophil adhesion was studied after subcutaneous administration to six healthy individuals of human recombinant glycosylated G-CSF (lenograstim) (3 micrograms/kg) for 6 consecutive days. Basal adhesion and adhesion to E-selectin. VCAM-1 and ICAM-1 of neutrophil and eosinophil granulocytes were measured selectively. During G-CSF administration neutrophil basal adhesion increased from 7.4 +/- 3.9% (mean +/- SD) to 55.8 +/- 12.9% and 23.2 +/- 4.4%, 4 and 7 d, respectively, after start of the administration. At the same time points eosinophil basal adhesion increased from 7.1 +/- 2.4% to 37.7 +/- 6.1% and 13.1 +/- 5.3%, respectively. When adhesion was measured in the presence of Mn2+, which increases the functional activity of integrins, an even higher increase of neutrophil and eosinophil basal adhesion was noted 4 and 7 d, respectively, after start of G-CSF administration. In parallel with the enhanced basal adhesion neutrophil adhesion to E-selectin and ICAM-1 and eosinophil adhesion to E-selectin. VCAM-1 and ICAM-1 were significantly (P < 0.05) increased after 4 d of G-CSF administration as was neutrophil cell surface expression of CD11b and CD18. In vitro G-CSF induced minimal changes of granulocyte basal adhesion and inhibition of the adhesion to E-selectin. 10 ng/ml TNF alpha significantly increased neutrophil and eosinophil basal adhesion and adhesion to VCAM-1 and ICAM-1. In summary, administration of G-CSF to healthy subjects induced enhanced adhesion of neutrophil and eosinophil granulocytes, probably mediated by an increase of the functional capacity of beta 1- and beta 2-integrins. The induction of increased levels of TNF alpha might be one mechanism behind the in vivo effect of G-CSF administration.
