Follicular thyroid lesions: is there a discriminatory potential in the computerized nuclear analysis?

open access: yesEndocrine Connections, 2018
Background: Computerized image analysis seems to represent a promising diagnostic possibility for thyroid tumors. Our aim was to evaluate the discriminatory diagnostic efficiency of computerized image analysis of cell nuclei from histological materials ...

Induction of chromosome shattering by ultraviolet light and caffeine [PDF]

open access: yes, 1981
Synchronized and asynchronously growing cells of a V79 sub-line of the Chinese hamster were either partial-cell irradiation (λ, 254 nm) or laser-UV-microirradiated (λ, 257 nm).

The Mating-specific Gα Interacts with a Kinesin-14 and Regulates Pheromone-induced Nuclear Migration in Budding Yeast [PDF]

open access: yes, 2009
As a budding yeast cell elongates toward its mating partner, cytoplasmic microtubules connect the nucleus to the cell cortex at the growth tip.

Integral refractive index imaging of flowing cell nuclei using quantitative phase microscopy combined with fluorescence microscopy [PDF]

open access: yesOpt. Express 9, 1177-1189 (2018), 2019
We suggest a new multimodal imaging technique for quantitatively measuring the integral (thickness-average) refractive index of the nuclei of live biological cells in suspension. For this aim, we combined quantitative phase microscopy with simultaneous 2-D fluorescence microscopy.

Differences in the localization and morphology of chromosomes in the human nucleus [PDF]

open access: yes, 1999
Using fluorescence in situ hybridization we show striking differences in nuclear position, chromosome morphology, and interactions with nuclear substructure for human chromosomes 18 and 19.

The role of the nucleus for cell mechanics: an elastic phase field approach [PDF]

open access: yesarXiv, 2023
The nucleus of eukaryotic cells typically makes up around 30% of the cell volume and has significantly different mechanics, which can make it effectively up to ten times stiffer than the surrounding cytoplasm. Therefore it is an important element for cell mechanics, but a quantitative understanding of its mechanical role during whole cell dynamics is ...

Systems biology in the cell nucleus [PDF]

open access: yesJournal of Cell Science, 2005
The mammalian nucleus is arguably the most complex cellular organelle. It houses the vast majority of an organism's genetic material and is the site of all major genome regulatory processes. Reductionist approaches have been spectacularly successful at dissecting at the molecular level many of the key processes that occur within the nucleus ...

The connections of the inferior colliculus and the organization of the brainstem auditory system in the greater horseshoe bat (Rhinolophus ferrumequinum) [PDF]

open access: yes, 1981
The connections of the inferior colliculus, the mammalian midbrain auditory center, were determined in the greater horseshoe bat (Rhinolophus ferrumequinum), using the horseradish peroxidase method.

Advanced Multi-Microscopic Views Cell Semi-supervised Segmentation [PDF]

open access: yesarXiv, 2023
Although deep learning (DL) shows powerful potential in cell segmentation tasks, it suffers from poor generalization as DL-based methods originally simplified cell segmentation in detecting cell membrane boundary, lacking prominent cellular structures to position overall differentiating.

Transport in and out of the cell nucleus [PDF]

open access: yesBiochemical Society Transactions, 1998
A hallmark of eukaryotic cells is their separation into compartments. These compartments are surrounded by membranes that are impermeable to macromolecules. As most proteins are synthesised in the cytoplasm, specific transport systems have evolved to allow proteins to be imported from the cytoplasm into these compartments.
