摘要

In diabetic nephropathy (DN), hyperglycemia drives a progressive thickening of glomerular filtration surfaces,increased cell proliferation as well as mesangial expansion and a constriction of capillary lumens. This leads toprogressive structural changes inside the Glomeruli. In this work, we make a study of structural glomerular changesin DN from a graph-theoretic standpoint, using features extracted from Minimal Spanning Trees (MSTs) constructedover intercellular distances in order to classify the “packing signatures” of different DN stages. We furtherinvestigate the significance of the competing effects of Volume change measured here in 2Dimensional Pixel spanarea (Area) on one hand and increased cell proliferation on the other in determining the packing patterns. Towardsthat we formulate the problem as Dynamic Bayesian Network (DBN). From our preliminary results we do postulatethat volume expansion caused by internal pressure as capillary lumens constriction has perhaps has a greater effectin the early stages.
