The angioarchitecture of the coeliac sympathetic ganglion complex (CGC) of the common tree shrew (Tupaia glis) was studied by the vascular corrosion cast technique in conjunction with scanning electron microscopy. The CGC of the tree shrew was found to be a highly vascularised organ. It normally received arterial blood supply from branches of the inferior phrenic, superior suprarenal and inferi...

Comparative studies of locomotion indicate that limb design and performance are very similar in adult mammals of small to medium size. The present study was undertaken to test whether basic therian limb pattern is present during postnatal development. Kinematic data were collected from juveniles of two eutherian species in a cross-sectional study, using cinevideography. The tree shrew Tupaia gl...

Background: The impact method was used to make unilateral femoral comminuted fractures in tree shrews, which were then intravenously injected with lipopolysaccharide create a traumatic systemic inflammatory response syndrome model. Methods: treatment group infused shrew umbilical cord mesenchymal stem cells via the tail vein. After 10 days of treatment, 6 shrews killed control, model and groups...

Denial of Service attacks are frequently presenting an increasing threat to the global inter-networking infrastructure in networking area . The algorithm for TCP congestion control algorithm is highly efficient for the various networking areas and operations as well its internal assumption of end-system cooperation results are well prone to attack by high-rate flows. A Shrew attack uses the con...

Tree shrews are small mammals that bear some semblance to squirrels, but are actually close relatives of primates. Thus, they have been extensively studied as a model for the early stages of primate evolution. In this study, subdivisions of cortex were reconstructed from brain sections cut in the coronal, sagittal, or horizontal planes, and processed for parvalbumin, SMI-32-immunopositive neuro...

Protocols suitable for repeated magnetic resonance imaging (MRI) studies of the tree shrew's brain were established. This included the development of (i) a technique for prolonged inhalation anesthesia by endotracheal intubation; (ii) a reproducible fixation of the animal's head in a stereotaxic frame and finally (iii) the set-up of the hardware (rf coil) and software (MRI sequences) of the MRI...

Myopia in the lid-sutured tree shrew (Tupoia g/is) Many mammals reared with visual deprivation display abnormally poor visual behavior while using their deprived eyes1-4,9,1°. These results typically have been attributed to defective development of the central visual pathways during the deprivation 6 s,11,13. However. it is important to consider non-neural (e.g., optical) sources which might co...

To examine the susceptible period for deprivation-induced myopia, six groups of tree shrew pups (Tupaia glis belangeri) were monocularly deprived for 12 days with an opaque occluder starting 7, 15, 21, 33, 48, or 63 days after natural eyelid opening. Compared to the untreated fellow control eye, significant myopia and vitreous chamber elongation were produced by the deprivation in all six group...

Increasing evidence suggests that unknown collagen remodeling mechanisms in the sclera underlie myopia development. We are proposing a novel organ culture system in combination with two-photon fluorescence imaging to quantify collagen remodeling at the tissue- and lamella-level. Tree shrew scleral shells were cultured up to 7 days in serum-free media and cellular viability was investigated unde...
