Development of a Biological Dosimeter for Translocation Scoring Based on Two-Color Fluorescence in Situ Hybridization of Chromosome Subsets [PDF]

open access: yes, 1992
Recently fluorescence in situ hybridization protocols have been developed which allow the paining of individual chromosomes using DNA-libraries from sorted human chromosomes.

First report on a multiple sex chromosome system (X1X2X30) and population variations in the frequency of ring bivalents in Pyrrhocoridae (Hemiptera: Heteroptera)

open access: yesEuropean Journal of Entomology, 2015
The family Pyrrhocoridae (Hemiptera: Heteroptera) is characterized by a modal diploid chromosome number of 16 (♂) ranging from 12 to 33 and simple (X0), multiple (X1X20) and neo-sex chromosome systems (neoX-neoY).

Chromosomal aberrations in transitional cell carcinoma that are predictive of disease outcome are independent of polyploidy [PDF]

open access: yes, 1999
Objective To determine whether aneusomy for chromosomes 7, 9 and 17 (reported to predict recurrence in up to 65% of patients with superficial transitional cell bladder cancer and thus providing the opportunity for early and effective treatment) reflects ...

A chromosomal study on a Lebanese spittlebug Philaenus arslani (Hemiptera: Auchenorrhyncha: Aphrophoridae)

open access: yesEuropean Journal of Entomology, 2008
The meadow spittlebug genus Philaenus (Auchenorrhyncha: Aphrophoridae) is known to display marked colour polymorphism. This study presents the results of a karyotype analysis of P.

Chromosome Centromeres: Structural and Analytical Investigations with High Resolution Scanning Electron Microscopy in Combination with Focused Ion Beam Milling [PDF]

open access: yes, 2009
Whole mount mitotic metaphase chromosomes of different plants and animals were investigated with high resolution field emission scanning electron microscopy (FESEM) to study the ultrastructural organization of centromeres, including metacentric ...

Rapid metaphase and interphase detection of radiation-induced chromosome aberrations in human lymphocytes by chromosomal suppression in situ hybridization [PDF]

open access: yes, 1990
Chromosomal in situ suppression (CISS)-hybridization of biotinylated phage DNA-library inserts from sorted human chromosomes was used to decorate chromosomes 1 and 7 specifically from pter to qter and to detect structural aberrations of these chromosomes

Chromosome Structure: Coiling up chromosomes [PDF]

open access: yesCurrent Biology, 1995
The mechanism by which eukaryotic chromosomes condense as cells enter mitosis has long been inaccessible to molecular biologists. An important clue has now been provided by a ubiquitous protein family, the SMCs.

Detection of chromosome aberrations in metaphase and interphase tumor cells by in situ hybridization using chromosome-specific library probes [PDF]

open access: yes, 1988
Chromosome aberrations in two glioma cell lines were analyzed using biotinylated DNA library probes that specifically decorate chromosomes 1, 4, 7, 18 and 22 from pter to qter.

DNA methylation profiling of human chromosomes 6, 20 and 22

open access: yesNature Genetics, 2006
DNA methylation is the most stable type of epigenetic modification modulating the transcriptional plasticity of mammalian genomes. Using bisulfite DNA sequencing, we report high-resolution methylation profiles of human chromosomes 6, 20 and 22, providing

Deep Anomaly Generation: An Image Translation Approach of Synthesizing Abnormal Banded Chromosome Images

open access: yesIEEE Access, 2022
Advances in deep-learning-based pipelines have led to breakthroughs in a variety of microscopy image diagnostics. However, a sufficiently big training data set is usually difficult to obtain due to high annotation costs.
