Morphology of cells changed and nuclei exhibited features of programmed cell death.
Urine cytology demonstrated necrotic debris, reactive squamous cells and degenerate cells with nuclei showing features of probable viral cytopathic effect.
Finally, the fourth stage of the computer analysis consisted of using the logistic regression analysis [ 35] to construct an equation, using nuclei properties (features), for assessing a laryngeal lesion's probability of being of either low or high histological grade of laryngeal cancer.
The results showed that a large fraction of the cis-UCA-exposed 5637 cells displayed nuclei with characteristic apoptotic features, including nuclear condensation and fragmentation.
While it is generally agreed that eukaryotic nuclei share more features in common with archaea rather than with bacteria, different studies have identified either one or the other of the two major groups of archaea as potential ancestors, leading to somewhat of a stalemate.
Pathologists use morphological features of nuclei to distinguish different cell types and to identify abnormal cells within tissues.
The cells were observed under a fluorescence microscope for nuclei showing typical apoptotic features such as chromatin condensation and fragmentation.
