We have compared the accumulation of recombinant variable heavy-chain portions [VHH (variable heavy-chain antibody from camelids)] of camelid antibodies in a variety of subcellular compartments produced in planta. The VHH coding sequences were optimized for expression in thale cress (Arabidopsis thaliana) and placed individually or as fused tandem(More)
Registration of histopathology images of consecutive tissue sections stained with different histochemical or immunohistochemical stains is an important step in a number of application areas, such as the investigation of the pathology of a disease, validation of MRI sequences against tissue images, multiscale physical modeling, etc. In each case, information(More)
Pathological cardiac fibrosis is important in predisposing the heart to arrhythmia and mechanical failure. The regional distribution of fibrosis is often described qualitatively and quantitatively in histological studies of animal hearts after staining collagen with specific colored stains. Currently this description is often piecemeal, as it lacks rigorous(More)
The utility of satellite imagery for landslide detection in southwest coastal British Columbia was evaluated by interpretation of orbital imagery (SPOT, IKONOS, and QUICKBIRD) and comparison with large-and medium-scale aerial photography. Satellite imagery was enhanced by simple, repeatable digital image processing techniques (contrast stretches and(More)
The isolated, perfused rat lung preparation was modified to allow characterized solid aerosol delivery. Deposition and airway-to-perfusate transfer of disodium fluorescein from 3-4 micron dae solid aerosols were studied under different ventilatory regimes. The lungs inhaled from an aerosol stream of constant concentration via a tracheal cannula. Air(More)
A variety of single-chain variable fragments (scFv) that had been previously developed to the surface epitopes of infective Trichostrongylus colubriformis L3 pathogenic gut nematodes of sheep were fused to a trimeric version of polyoleosin (three head-to-tail repeats of oleosin) and expressed in planta under the control of an Arabidopsis oleosin promoter.(More)
Three-dimensional (3D) high resolution microscopic images have high potential for improving the understanding of both normal and disease processes where structural changes or spatial relationship of disease features are significant. In this paper, we develop a complete framework applicable to 3D pathology analytical imaging, with an application to whole(More)

In 2012, there was a sharp increase in human immunodeficiency virus (HIV) notifications in New South Wales (NSW), Australia, following a 10-year period of relative stability. This increase, among other factors, triggered the development of a new HIV strategy that included renewed efforts to increase testing to improve early diagnosis, enable early treatment(More)
