The presence of primary spermatocytes at two different stages, specifically zygotene and diplotene, with large nuclei
observed in spermatocytes in the diplotene stage, was the other notable characteristic of this stage.
The cells were polyhedral in shape with prickle borders and large nuclei
. The surrounding connective tissue was fibrous containing blood vessels engorged with RBCs.
C) An electron photomicrograph of an ultrathin section of the reversal group four (32 days to low altitude after exposure to the same period at high altitude) rat's testis showing spermatogonia (SP) with their nuclei (N) resting on the basal lamina (BL) primary spermatocytes (PS) with large nuclei
They are called super-heavy elements because they are literally heavy, with very large nuclei
. Element 118 is the heaviest element discovered so far.
There is also one generation of large nuclei
with modality shift to the right (Figure 3b).
It consisted of nests of cells with abundant cytoplasm and large nuclei
. For the most part, the tumour structure was intact (Fig.
Large volume, dense cytoplasm and one or two large nuclei
are evident in the tapetal cells at this point.
Long handle provides good grip and is very useful to apply sufficient tangential pressure during delivery of large nuclei
. There is no need to pull/retract the superior rectus bridle suture while delivering the nucleus.
Histological examination showed groups of small cells with large nuclei
and small cytoplasms in the dermis, with abnormal mitoses (Figure 2).
But the current thinking is that the subtypes most prone to local recurrence include extensive LCIS with more than 10 involved lobules, LCIS with necrosis, pleomorphic tumors, and lesions containing cells with large nuclei
Colleter cells have thin walls, dense cytoplasm, large nuclei
, many mitochondria, rough endoplasmic reticulum, and abundant dictyosomes.
The red giants and supergiants produce large nuclei
copiously in their interiors, the novae and supernovae do so explosively, and the magnetic stars manufacture heavy elements near their surfaces by the betatron effect....
