For sperm head morphology, 500 spermatozoa were examined in Williams-stained slides using a light microscope at 1,000× magnification, and the numbers of sperm head abnormalities (pear shape, narrow-based, abnormal contour, lack of development, narrowness, abaxial implantation, and abnormal loose heads) were identified.
However, due to variations in tumor shape and lack of centering of the original segmentation, minimum contour expansions of 15 mm (seg1 2) and 11 mm (seg3) would have been needed to fully cover all Gleason ≥ 7 disease.
Unusual cell shape and lack of cell spreading can cause cell death in each of the cell types studied here [36], which may explain the observed decrease in cell survival and proliferation rate of TNAs.
Breads with added fat, like challah and brioche, will take longer to go stale, whereas a baguette — because of its narrow shape and lack of fat — is an extreme case and will go stale very rapidly.
Abnormal shape and lack of motility of Δ sas6 tubulin microgametes suggested that the underlying microtubular structure of axonemes is defective in Δ sas6 male gametocytes similar to what has been reported in SAS-6 Chlamydomonas mutants and Drosophila SAS-6 mutant spermatids (Nakazawa et al., 2007; Rodrigues-Martins et al., 2007).
We tangle our worth up in the numbers our weight adds up to, in our shapes, curves, lack of curves, in our height and size.
The result--the first complete structure of a virus in the flavivirus family--reveals a layered, soccer-ball-like shape lacking the spiky projections characteristic of many human viruses, the researchers report in the 8 March issue of Cell.
These observations include 1) polygonal crystal shape suggesting equilibrium growth (Figure 1); 2) lack of detectable compositional zoning in crystals (>20 μm); and 3) lack of compositional heterogeneity of melt (based on small standard deviations of replicate analyses, Table 4).
Since MLS shape functions are lack of the Kronecker delta function property, the penalty method is applied to enforce the essential boundary conditions.
The models predict the elongated shape and a lack of interaction with visible matter.
