Chromosomes of the tree shrews (Tupaiidae)
Cytogenetic and Genome Research, 1969Chromosomes from seven species of Tupaiidae, including <i>Tupaia glis</i>, <i>T. chinensis</i>, <i>T. longipes</i>, <i>T. montana</i>, <i>T. minor</i>, <i>T. palawanensis</i> and <i>Urogale everetti</i>, were analyzed.

Adenoviral infection in infant tree shrews
Journal of the American Veterinary Medical Association, 1984Summary An epizootic of fatal illness among infant common tree shrews (Tupaia glis) occurred in a research colony. Affected tree shrews were dehydrated, and ingested milk substitute remained in their stomachs for several hours without being digested. Twelve of 15 tree shrews born during a 3-month period died.

Most biarmed chromosomes are morphologically distinct. Among the acrocentrics, one pair is outstandingly large. Some small ones have secondary constrictions. One or two pairs of the small acrocentrics may have a short second arm; thus they may be regarded as small subtelocentric.

Spontaneous malignomas in Tupaia (tree shrew)
American Journal of Primatology, 1982AbstractNine spontaneous malignomas of the tree shrew were detected and analysed during an observation period of nine years. The tumours were histopathologically examined and classified. All malignomas developed in imported Tupaia only. From the tumour cells of two different animals new Tupaia herpesviruses were isolated. This is the first.

A novel tree shrew model of pulmonary fibrosis
Laboratory Investigation, 2021Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic lung disease without effective therapy. Animal models effectively reproducing IPF disease features are needed to study the underlying molecular mechanisms. Tree shrews are genetically, anatomically, and metabolically closer to humans than rodents or dogs; therefore, the tree shrew model ...

Interlaminar connections of tree shrew visual cortex
Neuroscience Letters, 1979The intracortical projections of neurons in layers II and upper III of tree shrew visual cortex were studied after terminal lesions in the supragranular layers of area 17. Examination for terminal degeneration was made using ultrastructural techniques.

Tree shrew (Tupaia) herpesviruses.
Developments in biological standardization, 1983Five Tupaia herpesviruses have been isolated until now: four in our laboratory which were termed THV-2, 3, 4, and 5, whereas THV-1 has been isolated by Melnick and his colleagues. THV-2 was isolated from tumour cell culture of a high-grade malignant lymphoma of a Tupaia, THV-3 was released from a cell culture of another Tupaia lymphoma, THV-4 from a ...

Spatial contrast sensitivity of the tree shrew
Vision Research, 1984Spatial contrast sensitivity functions (CSFs) were measured for 3 tree shrews. Our two-alternative forced-choice discrimination paradigm required the animals to discriminate a vertical sine-wave luminance grating from a homogeneous field of the same size (16 degrees) and mean luminance (35 cd/m2). Spatial frequencies tested ranged from 0.1 to 2.0 c/deg

Forelimb Morphology of Tree Shrews
2015The chapter includes three subchapters—Skeleton, Joints and Musculature, which describe, respectively, osteology, syndesmology and myology of the shoulder girdle and forelimb in Tupaia belangeri, one of the most generalized members of the order Scandentia.

1980
Fossils directly contribute to the construction of phylogenies in two ways. They provide additional samples (usually taxa) which are used in biological comparisons, so far as the completeness of the fossil material warrants, in order to determine morphocline polarity; that is, in forming a hypothesis of primitive and derived character states.
