The susceptibility of the tree shrew Tupaia belangeri to human hepatitis B virus (HBV) has been demonstrated both in vivo and in vitro. In this study, we show that purified HBV infects primary T. belangeri hepatocyte cultures in a very specific manner, as detected by HBV covalently closed circular DNA, mRNA, HBV e antigen, and HBsAg production. A monoclonal(More)
Size-dependent structural patterns in the conductive bronchial tree of four species of myomorph rodents of different body weight were determined by lung casts. The lungs of the harvest mouse, Micromys minutus, body weight 5-7 g, the house mouse, Mus musculus, body weight 35-45 g, the brown rat, Rattus norvegicus, body weight 200-400 g, and the African giant(More)
Macroscopic identification and surgical removal of the mouse parotid gland is demanding because of its anatomic location and size. Moreover, the mouse parotid gland contains high concentrations of RNases, making it difficult to isolate high-quality RNA. So far, appropriate methods for optimal perfusion-fixation and dissection of mouse parotid glands, as(More)
Patients with mild forms of peroxisomal biogenesis disorders show facial dysmorphism and exhibit dentition problems accompanied by enamel hypoplasia. However, no information is available on the role of peroxisomes in dental and paradontal tissues. Therefore, we studied the distribution of these organelles, their protein composition and the expression of(More)
The objective of this study was to examine the normal respiratory tract of grey parrots and amazons by using two different methods. The lower respiratory tract of five amazons and four grey parrots, all healthy, were investigated applying computerised tomography (CT). Volumes and densities of the body, the body cavities, the normal lungs, and the airsacs in(More)
