The prion protein and New World primate phylogeny

open access: yesGenetics 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 ...

Fast and non-invasive PCR sexing of primates: apes, Old World monkeys, New World monkeys and Strepsirrhines

open access: yesBMC Ecology, 2006
Background One of the key tools for determining the social structure of wild and endangered primates is the ability to sex DNA from small amounts of non-invasive samples that are likely to include highly degraded DNA.

Easy rider: monkeys learn to drive a wheelchair to navigate through a complex maze. [PDF]

open access: yesPLoS ONE, 2014
The neurological bases of spatial navigation are mainly investigated in rodents and seldom in primates. The few studies led on spatial navigation in both human and non-human primates are performed in virtual, not in real environments.

Non-invasive Eye Tracking Methods for New World and Old World Monkeys

open access: yesFrontiers in Behavioral Neuroscience, 2019
Eye-tracking methods measure what humans and other animals visually attend to in the environment. In nonhuman primates, eye tracking can be used to test hypotheses about how primates process social information.

Intestinal capillariasis in New World monkeys

open access: yesJournal of Medical Primatology, 1994
Two cases of intestinal capillariasis have been identified at necropsy in a squirrel monkey and a capuchin monkey born and raised in captivity. The parasites are described as far as possible from the histopathological slides or intestinal contents, and their relationship to other intestinal capillarids, especially those of primates, is discussed.

GABA-induced inactivation of Cebus apella V2 neurons: effects on orientation tuning and direction selectivity

open access: yesBrazilian Journal of Medical and Biological Research, 2013
We investigated the GABA-induced inactivation of V2 neurons and terminals on the receptive field properties of this area in an anesthetized and paralyzed Cebus apella monkey.

Computational modeling of oxytocin-receptors interactions with the common marmoset Callithrix jacchus Pro8OT variant [PDF]

open access: yesGenetics and Molecular Biology
The oxytocinergic system plays a crucial role in regulating physiological and behavioral processes, making it a key component of neurobiology in both humans and animals.

Serological evidence for Saint Louis encephalitis virus in free-ranging New World monkeys and horses within the upper Paraná River basin region, Southern Brazil

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2014
Introduction Saint Louis encephalitis virus (SLEV) primarily occurs in the Americas and produces disease predominantly in humans. This study investigated the serological presence of SLEV in nonhuman primates and horses from southern Brazil.

Comprehensive characterization of evolutionary conserved breakpoints in four New World Monkey karyotypes compared to Chlorocebus aethiops and Homo sapiens

open access: yesHeliyon, 2015
Comparative cytogenetic analysis in New World Monkeys (NWMs) using human multicolor banding (MCB) probe sets were not previously done. Here we report on an MCB based FISH-banding study complemented with selected locus-specific and heterochromatin ...
