Comparative Efficiency of Multiple eDNA Sampling Methods for Monitoring Vertebrate Diversity in Mountainous Region

Environmental DNA, Volume 7, Issue 4, July–August 2025.
This study evaluates the effectiveness of three environmental DNA sampling approaches–water eDNA, air eDNA, and leech‐derived iDNA–for surveying vertebrate diversity in the Gaoligong Mountains of southwest China. Using five metabarcoding primer sets, we detected 235 vertebrate species.

The spectral transmission of ocular media suggests ultraviolet sensitivity is widespread among mammals [PDF]

, 2014
Although ultraviolet (UV) sensitivity is widespread among animals it is considered rare in mammals, being restricted to the few species that have a visual pigment maximally sensitive (λmax) below 400 nm.

High‐throughput markerless pose estimation and home‐cage activity analysis of tree shrew using deep learning

Animal Models and Experimental Medicine, Volume 8, Issue 5, Page 896-905, May 2025.
We present a deep learning approach to achieve markerless pose estimation and recognize multiple spontaneous behaviors of tree shrews. This high‐throughput approach can monitor the home‐cage activities of 16 tree shrews simultaneously over an extended period.

Animal models to study hepatitis C virus infection [PDF]

, 2018
With more than 71 million chronically infected people, the hepatitis C virus (HCV) is a major global health concern. Although new direct acting antivirals have significantly improved the rate of HCV cure, high therapy cost, potential emergence of drug ...

Pulmonary histiocytosis in tree shrews (Tupaia belangeri).

Laboratory animal science, 1997
Granulomatous lesions similar to those of pulmonary histiocytosis in rats developed spontaneously in the lungs of captive tree shrews. Incidence peaked in 3-year-old tree shrews. Sex dependency was not observed, and development of the granulomas was unrelated to experimental procedures because the lesions were observed in animals from the breeding ...

Animal models of human herpesvirus infection

Animal Models and Experimental Medicine, Volume 8, Issue 4, Page 615-628, April 2025.
Human herpesvirus can infect humans and other vertebrates, primarily targeting the skin, mucous membranes, and neural tissues, thereby significantly impacting the health of both humans and animals. Animal models are crucial for studying virus pathogenesis, vaccine development, and drug testing.

MHC class I genes of the tree shrew Tupaia belangeri

Immunogenetics, 2002
Two MHC class I cDNA sequences from the tree shrew (Tupaia belangeri), Tube-W01 and Tube-W02, have been isolated which are probably derived from classical class I genes. Expression of the tupaia class I genes was investigated in several organs, in particular the brain, in which slightly different amounts of class I transcripts are detectable in ...

On the development of the chondrocranium and the histological anatomy of the head in perinatal stages of marsupial mammals [PDF]

, 2017
An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides ...

A Single‐Nucleus Transcriptomic Atlas Reveals Cellular and Genetic Characteristics of Alzheimer's‐Like Pathology in Aging Tree Shrews

MedComm, Volume 6, Issue 4, April 2025.
We present a novel Alzheimer's disease (AD) model using naturally aging tree shrews (TSs) that exhibit Alzheimer's‐like pathology (ALP), offering unique insights into human AD progression. Through single‐nucleus RNA sequencing, we mapped the hippocampal transcriptome, revealing key neural progenitor cell differentiation trajectories linked to AD. Cross‐

Effects of Gradient Photoperiod and Temperature on Energy Metabolism and Body Composition in Tupaia belangeri chinensis [PDF]

Journal of Stress Physiology & Biochemistry, 2013
In order to explore the adaptive changes in energy metabolism and body composition in response to a gradual reduction in both ambient temperature and photoperiod, male adult tree shrews Tupaia belangeri chinensis were raised under the conditions of 30 oC
