Since expression of Serpins may facilitate the immune escape of HLA positive tumors, we next analysed the effect of Serpin expression on survival in cases with normal/partial

C- 13 C dipolar correlation photo-CIDNP MAS NMR studies have been performed in Chapter 4 on RCs of Rhodobacter sphaeroides WT, selectively isotope labelled in

De overeenkomst tussen het photo-CIDNP spectrum van de geïsoleerde RC’s en de intacte cellen duidt erop dat de electronenstructuur van de grondtoestand van het

The difference in the photo-CIDNP signals from the donor and the acceptor in Rhodobacter sphaeroides R26 is due to the slow relaxation of the triplet state of the donor.. Chapter

Photochemically induced dynamic nuclear polarisation (photo-CIDNP) is observed in frozen and quinone-depleted photosynthetic reaction centers of the purple bacteria

Peripheral blood cells were stained with HLA-A2.1 tetramers containing the tyrosinase368–376 peptide followed by staining with a panel of lineage antibodies, as described in

Blades and blade fragments seem to have been especially used for longitudinal motions, mainly on plant material (7/12). Flake and flake fragments are used in different motions on

This shape also occurs in the combination artefacts (see below). The shape is the result of intensive use in a repetitive abrasive motion, carried out from different angles. In
