Gender and ploidy in cancer survival [PDF]

open access: yesCellular Oncology, 2011
Females carry a better prognosis than men for many cancer types. We hypothesized that chromosomal changes, in particular numerical alterations of the sex chromosomes or the presence of near-triploidy may contribute to these gender differences.To characterize the influence of gender a literature search was performed for survival data of 27 tumor types ...

The chromosome number and heterochromatin distribution pattern suggest differentiation among species of the Stylosanthes scabra-seabrana complex [PDF]

open access: yesAnais da Academia Brasileira de Ciências
The genus Stylosanthes has economic importance in semi-arid regions and requires studies that reveal complex relationships between species involving different ploidies.

Minority cytotypes in European populations of the Gymnadenia conopsea complex (Orchidaceae) greatly increase intraspecific and intrapopulation diversity [PDF]

open access: yes, 2017
Background and Aims Patterns of ploidy variation among and within populations can provide valuable insights into the evolutionary mechanisms shaping the dynamics of plant systems showing ploidy diversity.

Robust and highly informative microsatellite-based genetic identity kit for potato

open access: yesMolecular breeding, 2009
The fingerprinting of 742 potato landraces with 51 simple sequence repeat (SSR, or microsatellite) markers resulted in improving a previously constructed potato genetic identity kit.

Clinical significance of phenotyping and karyotyping of circulating tumor cells in patients with advanced gastric cancer

open access: yesOncoTarget, 2014
BACKGROUND Karyotyping and phenotyping of circulating tumor cells (CTCs) in therapeutic cancer patients is of particular clinical significance in terms of both identifying chemo-resistant CTC subtypes and understanding CTC evolution.

PLOIDY AND GENE EXPRESSION IN CLEMENTINE

open access: yesActa Horticulturae, 2015
Polyploidy has long been recognized as an important force in the evolution of flowering plants and often results in novel phenotypes having advantages in adaptation and major interest for agriculture. Many crops, including citrus, are bred to a higher level of ploidy in search of desirable traits.

Ploidy determination of Canadida albicans [PDF]

open access: yesJournal of Bacteriology, 1979
The dimorphic yeast Candida albicans, as a member of the fungi imperfecti, has been assumed to be in the haploid, or imperfect, state. The deoxyribonucleic acid content of this species has been measured by flow microfluorometry, a technique capable of analyzing single cells.

Population genomics reveals evolution and variation of Saccharomyces cerevisiae in the human and insects gut [PDF]

open access: yes, 2019
The quest to discover the variety of ecological niches inhabited by Saccharomyces cerevisiae has led to research in areas as diverse as wineries, oak trees, and insect guts.

Genome size variation and polyploidy incidence in the alpine flora from Spain

open access: yesAnales del Jardín Botánico de Madrid, 2013
The interest to study genome evolution, in particular genome size variation and polyploid incidence, has increased in recent years. Still, only a few studies have been focused at a community level.
