The purpose of this study was to determine the kinetics of HSP70 expression in response to mild thermal stress. The rationale is to produce a basis for design of optimal heating methods to induce HSP70 expression for preconditioning in cardiac surgery. Bovine aortic endothelial cells were heated at 42 degrees C for 0.5 to 5 hours followed by 37 degrees C(More)
The direct correlation between levels of heat shock protein expression and efficiency of its tissue protection function motivates this study of how thermal doses can be used for an optimal stress protocol design. Heat shock protein 70 (HSP70) expression kinetics were visualized continuously in cultured bovine aortic endothelial cells (BAECs) on a microscope(More)
In this paper, we address the analysis of 3D shape and shape change in non-rigid biological objects imaged via a stereo light microscope. We propose an integrated approach for the reconstruction of 3D structure and the motion analysis for images in which only a few informative features are available. The key components of this framework are: 1) image(More)
We have developed a digital image analysis technique to assay the viability of frozen-thawed pancreatic islets by using laser scanning confocal microscopy (LSCM) in conjunction with double fluorescent staining [acridine orange/propidium iodide (AO/PI)]. Freshly isolated rat pancreatic islets were cultured for 18-24 h and then brought to a 2 M concentration(More)
The quantitative analysis of the depth of injury, penetration of therapeutic agents in tissues, and the regeneration of vascular patency after a graded degree of thermal injury requires a knowledge of the shape and spatial configuration of the vascular networks in the tissue. We have applied computational stereo vision techniques to describe the 3-D(More)
