Nuclear DNA Content of Fine Needle Aspirates of Invasive Ductal Carcinomas of the Breast
Analytical Cellular Pathology, 1997 Patients with aggressive breast cancers benefit from chemotherapy prior to surgery. If the biology of the breast cancers were better characterised pre‐operatively, more patients at risk could be offered chemotherapy.

Population Genomics Informs Resilience and Vulnerability of Habitat‐Building Coralline Algae
Evolutionary Applications, Volume 18, Issue 11, November 2025.ABSTRACT Maerl beds, formed by free‐living coralline red algae, are biodiversity‐rich and carbon‐storing habitats of high conservation value but remain understudied at the genomic level. Here, we present the first draft genomes and population genomic analyses for two dominant maerl‐forming species in the north‐east Atlantic, Phymatolithon calcareum and

Gayana: Botanica, 2006 Mitotic chromosome counts in Chilean pteridophytes confirm the diploidy described for Equisetum L. (2n = 216) and Blechnum L. (2n = 66), as well as the tetraploidy of Asplenium L. (2n = 144). Megalastrum spectabile (Kaulf.) A.R.Sm.

Mononuclear Diploidy at the Heart of Cardiomyocyte Proliferation [PDF]
Cell Stem Cell, 2017 Reporting in Nature Genetics, Patterson et al. (2017) show that adult mammalian hearts possess an innate capacity to regenerate, which depends on a small population of mononuclear diploid cardiomyocytes. These cells undergo karyokinesis and cytokinesis, raising the possibility that endogenous cardiac muscle cells can be stimulated to proliferate for ...

Cancer Science, Volume 116, Issue 10, Page 2882-2892, October 2025.Japanese tumor genomes with whole‐genome duplication are diversified by allele imbalance and chromothripsis. These structural abnormalities are linked to a poor prognosis for cancer patients. ABSTRACT Whole‐genome analyses have revealed that large‐scale structural variations (SVs) such as whole‐genome duplication (WGD) occur early in the development of

How admixed captive breeding populations could be rescued using local ancestry information
Molecular Ecology, Volume 34, Issue 19, October 2025.Abstract This paper asks the question: can genomic information be used to recover a species that is already on the pathway to extinction due to genetic swamping from a related and more numerous population? We show that a breeding strategy in a captive breeding program can use whole genome sequencing to identify and remove segments of DNA introgressed ...
