Chromosome Evolution in New World Monkeys (Platyrrhini) [PDF]

open access: yes, 2012
During the last decades, New World monkey (NWM, Platyrrhini, Anthropoideae) comparative cytogenetics has shed light on many fundamental aspects of genome organisation and evolution in this fascinating, but also highly endangered group of neotropical ...

A suture in time: The ontogeny of cranial suture morphology in mammals

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 501-516, March 2026.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

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

open access: yesBMC 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.

Blood ties: ABO is a trans-species polymorphism in primates [PDF]

open access: yes, 2012
The ABO histo-blood group, the critical determinant of transfusion incompatibility, was the first genetic polymorphism discovered in humans. Remarkably, ABO antigens are also polymorphic in many other primates, with the same two amino acid changes ...

SCANNING ELECTRON MICROSCOPIC INVESTIGATION OF DENTINAL TUBULES IN MONKEY DENTIN SCANNING ELECTRON MICROSCOPIC INVESTIGATION OF DENTINAL TUBULES IN Cebus apella DENTIN

open access: yesCiência Animal Brasileira, 2009
<div>The aim of the study was to investigate the number and diameter of the Cebus apella dentinal tubules. The roots of the Cebus apella teeth were examined in specific tooth locations: the apical, middle and cervical dentin.

Gorillas’ (Gorilla g. gorilla) knowledge of conspecifics’ affordances: intraspecific social tool use for food acquisition [PDF]

open access: yes, 2020
The use of tools, long thought to be uniquely human, has now been observed in other animal taxa including several species of birds, non-primate mammals as well as some non-human primate species.

Morphological Changes in Direct Pathway Striatal Neurons in a Rat Model of Tardive Dyskinesia

open access: yesMovement Disorders, Volume 41, Issue 1, Page 234-240, January 2026.
Abstract Background Tardive dyskinesia (TD) and drug‐induced parkinsonism (DIP) arise from prolonged dopamine antagonist use. Although D2 receptor hypersensitivity in the indirect pathway is a proposed mechanism, the role of the direct pathway remains unclear.

Valores de referência das provas de funções hepática, renal e de alguns eletrólitos em Cebus apella, anestesiados com cetamina Serum biochemical profile of healthy Cebus apella, anesthetized with ketamine

open access: yesCiência Rural, 1997
Foram analisadas 127 amostras de soro sangüíneo, obtidas de macacos-prego (Cebus apella), anestesiados com cetamina. Quantificaram-se as provas de função hepática (proteínas totais, albumina, glicose, bilirrubinas e atividade enzimática de ALT, AST e ALP)
