Karyological Characterization of the Endemic Iberian Rock Lizard, Iberolacerta Monticola (Squamata, Lacertidae): Insights into Sex Chromosome Evolution [PDF]

, 2013
[Abstract] Rock lizards of the genus Iberolacerta constitute a promising model to examine the process of sex chromosome evolution, as these closely related taxa exhibit remarkable diversity in the degree of sex chromosome differentiation with no clear ...

Comparative cytogenetics of Physalaemus albifrons and Physalaemus cuvieri species groups (Anura, Leptodactylidae) [PDF]

, 2014
Recently, Physalaemus albifrons (Spix, 1824) was relocated from the Physalaemus cuvieri group to the same group as Physalaemus biligonigerus (Cope, 1861), Physalaemus marmoratus (Reinhardt & Lütken, 1862) and Physalaemus santafecinus Barrio, 1965.

Heterochromatin heteromorphism in Holhymenia rubiginosa (Heteroptera: Coreidae)

European Journal of Entomology, 2008
Heterochromatin is one of the most dynamic components in the genome of species. Previous studies on the heterochromatin content and distribution in Heteroptera (insects with holokinetic chromosomes) have shown that the species belonging to the family ...

Sleep Apnea Syndrome Sensing at C-Band [PDF]

IEEE Journal of Translational Engineering in Health and Medicine, 2018
A non-intrusive sleep apnea detection system using a C-Band channel sensing technique is proposed to monitor sleep apnea syndrome in real time. The system utilizes perturbations of RF signals to differentiate between patient's breathing under normal and sleep apnea conditions. The peak distance calculation is used to obtain the respiratory rates.

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]

, 2017
BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Microevolutionary differentiation of cereal tetraploid species by formation of recombinant genomes

Вавиловский журнал генетики и селекции, 2016
The process of microevolutionary differentiation of cereals by formation of recombinant genomes was studied in dynamics (F6–F17) with tetraploid wheat-rye amphidiploids as examples. Evidence that joint growing of tetra ploid amphidiploids having a common

C-band polymorphism in non-Hodgkin lymphoma [PDF]

Hereditas, 2008
The pattern of heteromorphism in C‐band positive constitutive heterochromatin of human chromosomes Nos. 1, 9, and 16 was studied in peripheral lymphocytes from 78 patients with non‐Hodgkin lymphoma and 78 control individuals. The parameters of the heterochromatic regions analyzed were relative size, symmetry‐asymmetry within homologous pairs, and ...

Cytogenetic description of Bunocephalus doriae Boulenger, 1902 (Siluriformes: Aspredinidae) from the Paraná River (Misiones, Argentina)

Neotropical Ichthyology
In this work, Bunocephalus doriae was cytogenetically analyzed. A karyotype with a diploid number of 2n= 50 comprising 6m, 10sm, 6st, and 28a (FN= 72) chromosomes was observed.
