Karyotypes of two European species of the genus Lymnaea with disputable taxonomic status (Gastropoda: Pulmonata: Lymnaeidae) [PDF]

open access: yes, 2002
Karyotypes of Lymnaea corvus and L. occulta are studied for the first time and compared to the original data on Ukrainian populations of L. palustris and L. stagnalis.

Chromosomal in situ suppression hybridization of human gonosomes and autosomes and its use in clinical cytogenetics [PDF]

open access: yes, 1990
DNA libraries from sorted human gonosomes were used selectively to stain the X and Y chromosomes in normal and aberrant cultured human cells by chromosomal in situ suppression (CISS-) hybridization.

Karyotype and male meiosis in Spartocera batatas and meiotic behaviour of multiple sex chromosomes in Coreidae (Heteroptera)

open access: yesEuropean Journal of Entomology, 2006
The Coreidae (Heteroptera) have holokinetic chromosomes and during male meiosis the autosomal bivalents segregate reductionally at anaphase I while the sex chromosomes do so equationally. The modal diploid chromosome number of the family is 2n = 21, with

Chromosome number and genome size diversity in five Solanaceae genera

open access: yesCaryologia, 2019
Sixteen species of Solanaceae, belonging to five genera, were studied karyologically through chromosome counting, chromosomal measurement, and karyotype symmetry. Genome size (GS) estimation was performed on fifteen species using flow cytometry.

Evidence of Chromosomal Instability in Prostate Cancer Determined by Spectral Karyotyping (SKY) and Interphase FISH Analysis

open access: yesNeoplasia: An International Journal for Oncology Research, 2001
The way in which cytogenetic aberrations develop in prostate cancer (Cap) is poorly understood. Spectral karyotype (SKY) analysis of Cap cell lines has shown that they have unstable karyotypes and also have features associated with chromosomal ...

Visualizing dimensionality reduction of systems biology data

open access: yes, 2012
One of the challenges in analyzing high-dimensional expression data is the detection of important biological signals. A common approach is to apply a dimension reduction method, such as principal component analysis. Typically, after application of such a
