Structure granular

Measuring static granular structures by MRI incurs some complications. The majority of NMR/MRI experiments to date use heterogeneous particles, specifically, solid particles with liquid cores. Thus, a close packed array of such particles would not image as close packed but would show gaps because the solid shells would yield weak or no NMR signal. 

Long-term grasslands provide plenty of organic matter for humus formation. If the soil is not acidic or waterlogged, the soil fauna and flora create humus and the subsequent useful development of a porous crumb and granular structure. Porosity encourages root growth and the uptake of soil nutrients. 

In all these measurements the flocculated particles have a granular structure and no structured flocculation appears.

When the surface of the purified HeLa cell nucleus is observed by AFM (Fig. 5a), relatively smooth surface is seen, although many small projections and cavities can be identified (Fig. 5b). When the isolated nuclei are successively subjected to the detergent treatment and high-salt treatment on the glass substrate to remove the nuclear membrane and nucleoplasm, fibrous structures appear (Fig. 5c, d). A close examination by AFM classified the existence of granular structures ( 80 nm width)... 

Figure 5. (Continued) different panels (e and f for HeLa, j and k for chicken erythrocyte, and o and p for yeast). A section profile obtained along X-Y line shows a typical granular structure in die nucleus (e, j, o), and the peak-to-peak distance between the granular structure was distributed from 60 nm to 120 nm (e). The diickness of the chromatin fibers released out of die nucleus varied possibly due to the assembly of diinner fibers (f, k, p). A section profile for the spread fibers was obtained along X-Y line (f, k, p). Isolated HeLa cell nucleus was treated widi (r, s) or without (q) RNase. The treatment releases SOnmfiber from the nucleus. The histogram of die fiber width is shown in an inset of (s). Bars, 250 nm. (See Colour Plate 2.)...

Liposomes (without peptide) were labelled with rhodamine-PE in the lipid bilayer and in the inner compartment using FITC-dextrane 9000 and incubated with DCs for one hour. Figure 3 shows clearly that only in the case of AVE 3 and AVE 43 could a significant uptake be observed. The fluorescence inside the DCs is in the case of AVE 3 homogenously distributed in the cytosol, whereas in the case of AVE 43 the liposomes seem to be caught in granular structures, presumably endosomes. The PS causes the liposomes...
