Non-Carious Cervical Lesions in Wild Primates: Implications for Understanding Toothpick Grooves and Abfraction Lesions. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives In clinical settings, non‐carious cervical lesions (NCCLs) are often linked to abrasion, erosion, abfraction, or a combination of these factors. In archaeological and paleontological remains, the most common NCCL is the “toothpick groove,” yet little is known about the occurrence of these and other NCCLs in wild non‐human primates ...

The prion protein and New World primate phylogeny [PDF]

Genetics and Molecular Biology, 2004
The PrP C prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrP C is converted to PrP Sc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

Pairing and recombination features during meiosis in Cebus paraguayanus (Primates: Platyrrhini) [PDF]

BMC Genetics, 2009
Background Among neotropical Primates, the Cai monkey Cebus paraguayanus (CPA) presents long, conserved chromosome syntenies with the human karyotype (HSA) as well as numerous C+ blocks in different chromosome pairs. In this study, immunofluorescence (IF)

Sistemática, evolución y paleobiogeografía de los primates Platyrrhini [PDF]

Revista del Museo de La Plata, 2013
Estudios recientes acerca de las relaciones filogenéticas entre los primates platirrinos basados en datos morfológicos y moleculares, concuerdan en una división en tres familias: Atelidae, Pitheciidae y Cebidae, con la única excepción de Aotus, que ...

Endocranial shape variation and allometry in Euarchontoglires [PDF]

Scientific Reports
While brain size in primates and their relatives within Euarchontoglires is well-studied, less research has examined brain shape, or the allometric trajectories that underlie the relationship between size and shape.

WHAT DO NEOTROPICAL PRIMATES TELL US UNDER THE LOOK OF CYTOGENETICS? [PDF]

BAG. Journal of Basic and Applied Genetics, 2022
Cytogenetics studies in Neotropical Primates (Primates: Platyrrhini) have shown that these mammals comprise a heterogeneous group at the chromosomal level.

Patterns of MHC-G-Like and MHC-B Diversification in New World Monkeys. [PDF]

PLoS ONE, 2015
The MHC class I (MHC-I) region in New World monkeys (Platyrrhini) has remained relatively understudied. To evaluate the diversification patterns and transcription behavior of MHC-I in Platyrrhini, we first analyzed public genomic sequences from the MHC-G-

Do saki monkeys possess a grooming claw? [PDF]

Primate Biology, 2020
The presence of a grooming claw on the second toe is a characteristic of Strepsirrhini and tarsiers. There is also some evidence for the presence of a grooming claw in Platyrrhini.

Comparative gastrointestinal organ lengths among Amazonian primates (Primates: Platyrrhini)

American Journal of Biological Anthropology, 2023
AbstractObjectivesThe morphological features of the gastrointestinal tract (GIT) in mammals reflect a species' food niche breadth and dietary adaptations. For many wild mammals, the relationship between the structure of the GIT and diet is still poorly understood, for example, the GIT for frugivorous primates is usually classified as unspecialized and ...

Molecular Evidence Supports Five Lineages within Chiropotes (Pitheciidae, Platyrrhini)

Genes, 2023
Pitheciines have unique dental specializations among New World monkeys that allow them to feed on fruits with hard pericarps, thus playing a major role as seed predators. The three extant pitheciine genera, Pithecia, Cacajao and Chiropotes, are all endemic to the Amazon region. Because of the uncertainties about interspecific relationships, we reviewed
