Biogeographical karyotypic variation of Rhinophylla fischerae (Chiroptera: Phyllostomidae) suggests the occurrence of cryptic species

Comparative Cytogenetics, 2010
The genus Rhinophylla Peters, 1865 (Carolliinae: Phyllostomidae) comprises three species: R. pumilio Peters, 1865, R. fischerae Carter, 1966 and R. alethina Handley, 1966. Only the first two species have been cytogenetically studied to date.

Flying lemurs – The 'flying tree shrews'? Molecular cytogenetic evidence for a Scandentia-Dermoptera sister clade

BMC Biology, 2008
Background Flying lemurs or Colugos (order Dermoptera) represent an ancient mammalian lineage that contains only two extant species. Although molecular evidence strongly supports that the orders Dermoptera, Scandentia, Lagomorpha, Rodentia and Primates ...

Phylogenetic studies of the genus Cebus (Cebidae-Primates) using chromosome painting and G-banding

BMC Evolutionary Biology, 2008
Background Chromosomal painting, using whole chromosome probes from humans and Saguinus oedipus, was used to establish karyotypic divergence among species of the genus Cebus, including C. olivaceus, C. albifrons, C. apella robustus and C.

The Status of Telomerase Enzyme Activity in Benign and Malignant Gynaecologic Pathologies

Balkan Medical Journal, 2013
Background: Telomeres are essential for the function and stability of eukaryotic chromosomes. Telomerase consists of three subunits: human telomerase reverse transcriptase (hTERT), human telomerase RNA (hTR), and telomerase protein 1 (TP1).
