Characterization of nuclear morphology and nuclear matrices in ageing human fibroblasts

Mechanisms of Ageing and Development, 1992
It is believed that the mechanisms for cellular senescence may reside within the genome, however, the changes which occur in the DNA and the surrounding nuclear environment have not been well documented. As the dynamic skeletal framework of the nucleus, the nuclear matrix is poised to play a critical role in the ageing process. The nuclear matrix plays

Ordered bicontinuous double-diamond morphology in subsaturation nuclear matter

, 2005
We propose to identify the new "intermediate" morphology in subsaturation nuclear matter observed in a recent quantum molecular dynamics simulation with the ordered bicontinuous double-diamond structure known in block copolymers.

An integrative description of a population of Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya [PDF]

, 2018
In a moss sample collected from Mount Kulal in Kenya, a new population of Mesobiotus radiatus was found. Given that the original description of M. radiatus was based solely on the morphology observed by light microscopy and measurements based mostly on a

Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity [PDF]

, 2010
Molecular taxonomy is one of the most promising yet challenging fields of biology. Molecular markers such as nuclear and mitochondrial genes are being used in a variety of studies surveying marine nematode taxa.

Role of LINC proteins in plant nuclear morphology [PDF]

Plant Signaling & Behavior, 2008
A common fate of post-mitotic interphase plant nuclei is morphological differentiation into an array of shapes and sizes. Development of nuclear morphology occurs in a cell-specific manner and is influenced by cell shape and nuclear DNA content. The LINC (LITTLE NUCLEI) proteins are plant-specific nuclear coiled-coil proteins that appear to couple ...

Cellular and nuclear morphology…and calcium signaling: revealing the interplay between structure and function [PDF]

, 2012
Poster presentation: Calcium plays a pivotal role in relaying electrical signals of the cell to subcellular compartments, such as the nucleus. Since this one ion type is used by the cell for many processes a neuron needs to establish finely tuned calcium

Nuclear Morphology and the Biology of Cancer Cells [PDF]

Acta Cytologica, 2020
Background: For more than a century, diagnostic pathologists have used morphologic abnormalities of the nucleus as essential diagnostic features to distinguish benign from malignant cells. These features include nuclear enlargement and increased nuclear-to-cytoplasmic ratio, nuclear membrane irregularities, hyperchromasia, and abnormal chromatin ...

The central parsecs of active galactic nuclei: challenges to the torus

, 2014
Type 2 AGN are by definition nuclei in which the broad-line region and continuum light are hidden at optical/UV wavelengths by dust. Via accurate registration of infrared (IR) Very Large Telescope adaptive optics images with optical \textit{Hubble Space ...

Mrk 609: resolving the circum-nuclear structure with near-infrared integral field spectroscopy

, 2007
We present first results of near infrared J and H+K ESO-SINFONI integral field spectroscopy of the composite starburst/Seyfert 1.8 galaxy Mrk 609. The data were taken during the science verification period of SINFONI. We aim to investigate the morphology

Nuclear Spirals as Signatures of Supermassive Black Holes

, 2004
Recent high resolution images of spiral galaxies show wide varieties of features including nuclear spirals in the central parts. Some of the galaxies show grand-design nuclear spirals.
