Chromosome Segmentation Analysis Using Image Processing Techniques and Autoencoders [PDF]
arXiv, 2022 Chromosome analysis and identification from metaphase images is a critical part of cytogenetics based medical diagnosis. It is mainly used for identifying constitutional, prenatal and acquired abnormalities in the diagnosis of genetic diseases and disorders.

Intermittent transport of bacterial chromosomal loci [PDF]
, 2017 The short-time dynamics of bacterial chromosomal loci is a mixture of subdiffusive and active motion, in the form of rapid relocations with near-ballistic dynamics.

PLoS Genetics, 2021 Different species can find convergent solutions to adapt their genome to the same evolutionary constraints, although functional convergence promoted by chromosomal rearrangements in different species has not previously been found.

Masked conditional variational autoencoders for chromosome straightening [PDF]
arXiv, 2023 Karyotyping is of importance for detecting chromosomal aberrations in human disease. However, chromosomes easily appear curved in microscopic images, which prevents cytogeneticists from analyzing chromosome types. To address this issue, we propose a framework for chromosome straightening, which comprises a preliminary processing algorithm and a ...

Chromosomal mutational algebra: a new algebra to manipulate chromosomal mutation [PDF]
, 2009 This study leads to a new algebra. An algebra is defined on the common mechanisms of chromosomal mutation. The algebra (_S^[PSI](C)_^, ~*~, ', [DELTA], _D_) is constructed for a given _C_ and [PSI].

Unified theory of human genome reveals a constrained spatial chromosomal arrangement in interphase nuclei [PDF]
, 2015 We investigate a densely packed, non-random arrangement of forty-six chromosomes (46,XY) in human nuclei. Here, we model systems-level chromosomal crosstalk by unifying intrinsic parameters (chromosomal length and number of genes) across all pairs of chromosomes in the genome to derive an extrinsic parameter called effective gene density.

Chromosomics: Bridging the Gap between Genomes and Chromosomes [PDF]
Genes, 2019 The recent advances in DNA sequencing technology are enabling a rapid increase in the number of genomes being sequenced. However, many fundamental questions in genome biology remain unanswered, because sequence data alone is unable to provide insight into how the genome is organised into chromosomes, the position and interaction of those chromosomes in

Molecular Biology of the Cell, 2011 Recent advances in our understanding of chromosome behavior have been made possible by the development of cutting-edge cytological and molecular techniques. Presentations in this Minisymposium applied these techniques to a diverse set of topics. Sarah Elgin (Washington University) described her lab’s studies on the 1360 transposable element in ...

Delineation of individual human chromosomes in metaphase and interphase cells by in situ suppression hybridization using recombinant DNA libraries [PDF]
, 1988 A method of in situ hybridization for visualizing individual human chromosomes from pter to qter, both in metaphase spreads and interphase nuclei, is reported.

Prevalence of Chromosomal Abnormalities in Infertile Couples in Romania
Balkan Journal of Medical Genetics, 2015 The purpose of this study was to establish a correlation between the presence of chromosomal abnormalities in one of the partners and infertility. This retrospective study was performed at the Department of Reproductive Medicine, Life Memorial Hospital ...
