Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The Intriguing Effects of Substituents in the N-Phenethyl Moiety of Norhydromorphone: A Bifunctional Opioid from a Set of “Tail Wags Dog” Experiments

open access: yesMolecules, 2020
(−)-N-Phenethyl analogs of optically pure N-norhydromorphone were synthesized and pharmacologically evaluated in several in vitro assays (opioid receptor binding, stimulation of [35S]GTPγS binding, forskolin-induced cAMP accumulation assay, and MOR ...

Squirrel monkey responses to information from social demonstration and individual exploration using touchscreen and object choice tasks [PDF]

open access: yesPeerJ, 2019
We aimed to study whether a non-human primate species responded differently to information acquired socially compared with that acquired individually. To do so, we attempted to train squirrel monkeys to perform binary discriminations.

Quantitative Analysis of Locus Coeruleus Neurons and Thalamic Noradrenergic Axons in a Progressive 1‐Methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine Monkey Model of Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease is mainly characterized by dopaminergic neurodegeneration in the substantia nigra pars compacta (SNc) and α‐synuclein accumulation. The locus coeruleus (LC) is also affected in Parkinson's disease and linked to some nonmotor symptoms, but the extent and timing of its degeneration remain unclear.

Photoacoustic imaging of squirrel monkey cortical and subcortical brain regions during peripheral electrical stimulation

open access: yesPhotoacoustics, 2022
The investigation of neuronal activity in non-human primate models is of critical importance due to their genetic similarity to human brains. In this study, we tested the feasibility of using photoacoustic imaging for the detection of cortical and ...

Experimental yellow fever virus infection in the squirrel monkey (Saimiri spp.) I: gross anatomical and histopathological findings in organs at necropsy [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 2020
BACKGROUND Non-human primates contribute to the spread of the yellow fever virus (YFV) and the establishment of transmission cycles in endemic areas. OBJECTIVE To describe the severe histopathological aspects of YFV infection, 10 squirrel monkeys were

More than proteins for empty stomachs: Wild meat in the BaTonga food system

open access: yesPeople and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

Chronic Wasting Disease Agents in Nonhuman Primates

open access: yesEmerging Infectious Diseases, 2014
Chronic wasting disease is a prion disease of cervids. Assessment of its zoonotic potential is critical. To evaluate primate susceptibility, we tested monkeys from 2 genera.
