Recent and rapid ecogeographical rule reversals in Northern Treeshrews
Scientific Reports, 2022 Two of the most-studied ecogeographical rules describe patterns of body size variation within species. Bergmann’s rule predicts that individuals have larger body sizes in colder climates (typically at higher latitudes), and the island rule predicts that ...

Preliminary observations on experimental leprosy in tupaias (Tupaia belangeri yunalis)
Leprosy Review, 1990 The Tupaia belangeri yunalis (tree shrew) is one of the primitive primates. They were inoculated subcutaneously in the footpad or intravenously with Mycobacterium leprae from a patient with multibacillary leprosy. As controls, the footpads of CFW mice were inoculated with the same suspension of M. leprae. The results showed growth of acid-fast bacilli (

Euarchontan opsin variation brings new focus to primate origins [PDF]
, 2016 Debate on the adaptive origins of primates has long focused on the functional ecology of the primate visual system. For example, it is hypothesized that variable expression of short- (SWS1) and middle-to-long-wavelength sensitive (M/LWS) opsins, which ...

Tree shrews (Tupaia belangeri) exhibit novelty preference in the novel location memory task with 24-h retention periods [PDF]
, 2014 Novelty preference is pervasive in mammalian species, and describes an inherent tendency to preferentially explore novelty. The novel location memory task studied here assesses the ability of animals to form accurate memories of a spatial configuration ...

Individual strategies of aggressive and non-aggressive male mice in encounters with trained aggressive residents [PDF]
, 1992 To determine whether individual differences in offensive behaviour are related to differences in defensive behaviour, the responses of male wild house mice, Mus domesticus, of an aggressive and a non-aggressive line to defeat by physically stronger ...

Construction of polyomavirus-derived pseudotype virus-like particles displaying a functionally active neutralizing antibody against hepatitis B virus surface antigen [PDF]
, 2015 Background: Virus-like particles (VLPs) can be efficiently produced by heterologous expression of viral structural proteins in yeast. Due to their repetitive structure, VLPs are extensively used for protein engineering and generation of chimeric VLPs ...

Requirement of Activation for Hepatitis B Virus Infection [PDF]
, 2007 Although _in vitro_ models of human hepatitis B virus replication are established, so far none could approximate infection efficiency as expected from _in vivo_ observations.

Intra- and Interspecies Analyses of the Carcinoembryonic Antigen (CEA) Gene Family Reveal Independent Evolution in Primates and Rodents [PDF]
, 1989 Various rodent and primate DNAs exhibit a stronger intra- than interspecies cross-hybridization with probes derived from the N-terminal domain exons of human and rat carcinoembryonic antigen (CEA)-like genes.

Molecular mechanism of the tree shrew's insensitivity to spiciness. [PDF]
PLoS Biology, 2018 Spicy foods elicit a pungent or hot and painful sensation that repels almost all mammals. Here, we observe that the tree shrew (Tupaia belangeri chinensis), which possesses a close relationship with primates and can directly and actively consume spicy ...
