Nuclear changes and morphology of the epidermis in the hibernating frog
Tissue and Cell, 1987Cytochemical changes of chromatin and DNA in frog epidermal cells were correlated with some morphological features to investigate the skin physiology during hibernation in comparison with the active period. The epidermal cells of hibernating frogs showed less condensed chromatin in all the layers; a greater loss of DNA was found during the transition ...

Cytoskeletal Control of Nuclear Morphology and Chromatin Organization
Journal of Molecular Biology, 2015The nucleus is sculpted toward various morphologies during cellular differentiation and development. Alterations in nuclear shape often result in changes to chromatin organization and genome function. This is thought to be reflective of its role as a cellular mechanotransducer. Recent evidence has highlighted the importance of cytoskeletal organization

Nuclear morphology of yeast under thymidylate starvation
Chromosoma, 1981During early meiotic development the yeast Saccharomyces cerevisiae has a characteristic nuclear dense body (NDB). It is shown that the NDB can also be induced in vegetatively growing cells through the inhibition of thymidylate synthetase which causes depletion of the dTMP pool and arrests DNA synthesis.

Nuclear Morphology and Grading in Tumours
1990von Hansemann (1890) is credited with first postulating that abnormalities of nuclear morphology in tumour cells might be correlated with their biological properties and clinical behaviour. He placed importance on the mitotic rate and the presence of abnormal mitoses (von Hansemann 1892).

Mathematical model of nuclear speckle morphology
2023Nuclear speckles are nuclear bodies consisting of populations of small and irregularly shaped droplet-like molecular condensates that contain various splicing factors. Recent experiments have shown the following morphological features of nuclear speckles: (I) Each molecular condensate contains SON and SRRM2 proteins, and

Classification of nuclear morphology in endocytoscopy of colorectal neoplasms
Gastrointestinal Endoscopy, 2017We investigated endocytoscopy (EC) findings that were considered risk factors for colorectal neoplasms and determined whether they could be used as new indices to identify carcinomas with massive submucosal invasion (SM-m) or worse outcomes.We performed a multivariate analysis of 8 factors on EC images to determine whether they were associated with SM ...

The morphology of interlinked porosity in nuclear fuels
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1975Abstract Micro-examination of irradiated uranium dioxide has shown that pores formed along triple-point grain edges play an important part in the swelling of the fuel. When the volume change is greater than 7 % this porosity has the form of long tunnels linking adjacent grain corners and forming an interconnected network throughout ...

Nuclear and Cytoplasmic Control of Morphology in Neurospora
1968Publisher Summary This chapter presents the nuclear and cytoplasmic control of morphology in Neurosporacrassa. The mechanism of control of the abn phenotype is closely related to the cytochrome pattern, which, in turn, is probably related to the overall metabolic pattern and to cell wall synthesis.

Morphology and nuclear contents in IVF embryos.
Annales de genetique, 1993Human pre-embryos, at 2-8 cells, with different morphology have been examined for chromosome constitution. Concerning the informative pre-embryos (23/65), 11 showed a normal karyotype and in 12 an abnormal karyotype was observed; there was not a complete correspondence between pronucleation and chromosome set.
