Abstract

In an effort related to urban operations, the United States Army has funded a research project for the University of Virginia (UVA) that includes the design and development of a reconfigurable information management system (RIMS) mission-specific deployments of unattended sensors. Using a highly flexible networking technology called HyperCast, the RIMS project hopes to provide information in a dynamic and adaptable fashion over disparate networks (Liebeherr 1999). As an early step in the RIMS, project, an experiment was performed to evaluate the prototype system's ability to be reconfigured and setup in different scenarios. By testing the time to configure and install the prototype, this experiment helps indicate the current system's ability to rapidly adjust. These results will act as an initial indication that the application of the reconfigurable concept can enhance the ability to rapidly set-up systems on a mission-specific basis.

Abstract

Background: Collagenous colitis is a disease characterized by chronic watery diarrhea, and on microscopic examination of colonic tissue, a typical thickening of the subepithelial collagen layer is seen. The etiology and pathophysiology behind this disease state are largely unknown., Methods: We have used in situ hybridization and immunohistochemistry to study the expression of transforming growth factor (TGF) -beta1, a growth factor with the capacity to cause accumulation of collagen in tissues, in collagenous colitis. Colonic pinch biopsy specimens from a total of 34 patients were investigated: 17 patients with collagenous colitis and 17 controls., Results: In patients with collagenous colitis there was increased expression of the TGF-beta1 gene compared with controls, as visualized by in situ hybridization. The vast majority of the TGF-beta1-expressing cells were eosinophils, both in collagenous colitis and controls, but there were also scattered fibroblastic and histiocytic stromal cells. Immunohistochemistry showed the presence of TGF-beta1, mainly in eosinophils, in the colonic mucosa. Morphometric quantification showed 603 +/- 192 eosinophils/mm2, (mean +/- standard error of the mean) in the colonic mucosa of patients with collagenous colitis compared with 30 +/- 7 eosinophils/mm2 in the controls., Conclusions: The present results suggest that eosinophils expressing TGF-beta1 may be of pathophysiologic importance in the connective tissue remodeling seen in collagenous colitis.
