Immunohistochemically Dyed Seminiferous Tubules With Feed-Forward Neural Network

Aydemir, Zubeyr | Erkaymaz, Okan | Akpolat Ferah, Mervem

Conference Object | 2017 | 2017 25TH SIGNAL PROCESSING AND COMMUNICATIONS APPLICATIONS CONFERENCE (SIU)

In this study, the features of the seminiferous tubule sections were extracted and the presence of the cells and cell stain types detected with the help of the feed forward artificial neural network. By looking at the section view with a small window, 78 features were extracted from the pixels seen by the window and used as an input to the artificial neural network. Artificial neural network outputs are decides presence of the cell and the staining of the cell. The results obtained with the artificial neural network were determined by using the connected component labeling method. The results obtained with the help of the user and t . . .he results obtained with the artificial neural network were compared. It has been shown that the proposed ANN model performs cell counting process comparable to the literature (%76 accuracy) Daha fazlası Daha az

Objective: Traumatic neuroma is an exuberant, probably nonneoplastic proliferation of a nerve occurring in response to injury or surgery. We studied six cases of traumatic neuroma with light microscopic, histochemical and immunohistochemical methods to assess the cellular compositions of these lesions. Material and Methods: Sections from the formalin-fixed parafin-embedded tissues were stained with hematoxylin-eosin, Gomori's trichrome, Verhoeff elastica-von Gieson, reticuline, and S-100 protein, Epithelial Membrane Antigen, CD34 and CD68. Results: All cases revealed large numbers of small and haphazardly arranged regenerating nerve . . . fascicles within a densely collagenous and fibroblastic stroma. A focal chronic mononuclear cell inflammatory reaction was observed in three cases. In all cases, Gomori's trichrome revealed collagen. Axonal morphology was detected in nerve fibers histochemically by reticulin. In all cases, fascicles were stained diffusely with S-100 protein, and Epithelial Membrane Antigen showed a positive reaction in a thin band of cells surrounding the fascicles in three of the cases. CD34 positive cells were present in five cases. CD68 expressing cells were present in only in two specimens. Conclusion: In traumatic neuromas, specific staining of fascicles with S-100 protein, perineural cells reactive for Epithelial Membrane Antigen and the presence of CD34 positive cells may contribute to our understanding of their pathogenesis and differentiation of these lesions from mimickers Daha fazlası Daha az
