Telomeric sequences distribution in nine Neotropical primates (Platyrrhinae) by (TTAGGG)n probe mapping: interstitial location and their possible role in evolution
No full textPlatyrrhini are characterized by a high intra and intergeneric genome variability. This
genome variability due to intra and inter-chromosomal rearrangements occurred
during evolution could be possibly link to the involvement of telomeric and
heterochromatin sequences. Telomeres, the terminal regions of chromosomes,
constituted of particular repeated DNA sequences (TTAGGG)n and proteins, are
called true telomeres and have their role in determining the replication and the
stability of chromosomes. The DNA component of telomeres can be also found at
intra-chromosomal sites such as close the centromeres and between centromere
and telomeres, and are known as Interstitial Telomeric Sequences (ITSs).
Traditionally considered just “junk DNA”, ITSs have been on the contrary associated
with chromosomal evolution even if their role has not been yet elucidated.
Chromosomal localization of ITS sequences was analyzed mapping telomeric
(TTAGGG)n sequence (PNA probe) by fluorescence in situ hybridization (FISH) on:
Callithrix argentata,Callithrix jacchus, Cebuella pygmaea, Saguinus oedipus, Saimiri
sciureus Aotus nacymaae, Aotus lemurinus griseimembra (Cebidae), Lagothrix
lagotricha (Atelidae), Callicebus moloch (Pithecidae). Telomeric sequences are
localized not only at the terminal ends of all chromosomes but our results indicate
that different types of ITSs (centromeric, interstitial and acrosubtelomeric) are
present into three among the nine analyzed, in Lagothrix lagotricha and the two
Aotus. We discuss ITSs possible role in chromosomal evolution and as potential
markers in phylogenetic studies for close related species. More molecular
cytogenetics studies will permit a better understanding of the mechanism of ITSs
origin and contribution to chromosomal evolution in Neotropical primates

Primatology in the Italian universities: from the colonial experience to the end of the XX century. In: Veracini, C. Casanova, C. Scalfari F Eds, History of Primatology: yesterday and today. The Mediterranean Tradition. Aracne Editrice: Ariccia (RM, Italy). Pp: 135-154
No full textBook's Abstract. Non–human primates have been perceived and classified with different approaches according to different cultural and philosophical traditions throughout the centuries. This book contains contributions that illustrate various aspects of the development of non-human primate natural history, starting from the ancient Greek world, through the Renaissance and European expansion, to the rise of Darwinism and finally to the work of Italian, French, Spanish and Portuguese scholars of the 20th and 21th centuries, concluding with an original work regarding the role of images in primate taxonomy and conservation
The evolution of the Cercopithecini: a (post)modern synthesis
No full textThe Cercopithecini, or African guenon monkeys, are one of the most diverse clades of living primates, and comprise the most species-rich clade of Catarrhini. Species identity is announced by flamboyant coloration of the facial and genital regions and, more cryptically, by vigorous chromosomal rearrangements among taxa. Beneath the skin, however, these animals are skeletally conservative between congeneric species. The guenons clearly demonstrate that morphological, cytogenetic, and reproductive differentiation proceed at different rates during speciation. We review diverse kinds of data in the effort to understand this conundru
An anthropological and paleopathological analysis of a peculiar skeleton from the Necropolis of Zancle (1st century BCE – 1st century CE): a case report
Full text linkThe work presents the results of the anthropological and paleopathological analysis carried out
on human skeletal remains of an individual (T-173) found in a burial from the necropolis “sector
96”, Messina, Sicily, dating back to the Roman Empire (1st century BCE – 1st century CE).
The study aimed to acquire the information necessary for the reconstruction of the biological
profi le. In fact, T173 is an adult male which is particularly interesting from a paleopathological
point of view, showing skeletal anomalies from the cranial to the post-cranial skeleton probably
caused by variations of genetic, neoplastic, articular and dental nature. Furthermore, the analyses
have highlighted the possible cause of death, related to two perimortem traumatic lesions on
parietal bones
