Coalescent-based genome analyses resolve the early branches of the euarchontoglires [PDF]

open access: yes, 2013
Despite numerous large-scale phylogenomic studies, certain parts of the mammalian tree are extraordinarily difficult to resolve. We used the coding regions from 19 completely sequenced genomes to study the relationships within the super-clade ...

A study of Epstein-Barr virus infection in the Chinese tree shrew(Tupaia belangeri chinensis)

open access: yesVirology Journal, 2017
Background Epstein–Barr virus (EBV) is closely associated with many human diseases, including a variety of deadly human malignant tumours. However, due to the lack of ideal animal models,the biological characteristics of EBV, particularly its function in

Whole-Brain Afferent Inputs to the Caudate Nucleus, Putamen, and Accumbens Nucleus in the Tree Shrew Striatum

open access: yesFrontiers in Neuroanatomy, 2021
Day-active tree shrews have a well-developed internal capsule (ic) that clearly separates the caudate nucleus (Cd) and putamen (Pu). The striatum consists of the Cd, ic, Pu, and accumbens nucleus (Acb).

Predation by Amphibians and Small Mammals on the Spruce Budworm (Lepidoptera: Tortricidae) [PDF]

open access: yes, 2017
Stomach-content analyses of pitfall-trapped amphibians and small mammals showed that the eastern American toad, Bujo americanus americanus, and the wood frog, Rana sylvatica, preyed on late instars and moths of the spruce budworm, Choristoneura ...

Varied behavioral responses induced by morphine in the tree shrew: a possible model for human opiate addiction

open access: yesFrontiers in Behavioral Neuroscience, 2014
Tree shrews represent a suitable animal model to study the pathogenesis of human diseases as they are phylogenetically close to primates and have a well-developed central nervous system that possesses many homologies with primates.

Aspects of tree shrew consolidated sleep structure resemble human sleep

open access: yesCommunications Biology, 2021
Dimanico et al investigated sleep in tree shrews using electrophysiological recordings and compared it to equivalent read-outs in rats and humans. They reported that there was considerable homology of sleep structure between humans and tree shrews ...

The tree shrew is a promising model for the study of influenza B virus infection

open access: yesVirology Journal, 2019
Background Influenza B virus is a main causative pathogen of annual influenza epidemics, however, research on influenza B virus in general lags behind that on influenza A viruses, one of the important reasons is studies on influenza B viruses in animal ...

The characterization of auditory brainstem response (ABR) waveforms: A study in tree shrews (Tupaia belangeri)

open access: yesJournal of Otology, 2018
To characterize the patterns of ABR waves in tree shrews, we must understand the hearing sensitivity and auditory function of healthy adult tree shrews.

Age-related changes of corneal endothelial cell in healthy Chinese tree shrew measured by non-contact specular microscope [PDF]

open access: yesInternational Journal of Ophthalmology, 2017
AIM: To determine the impact of age on the morphology of endothelial cells and central corneal thickness (CCT) in Chinese tree shrew. METHODS: One-hundred and twenty eyes of 60 healthy Chinese tree shrews were studied. Based on age, the tree shrews were
