Staining of toxoplasma in histological sections.

EXTRACELLULAR toxoplasma, although present in abundance in smears from animals infected experimentally, can only occasionally be found in sections from suspected toxoplasma lesions. In the eye, Wilder (1952a, b) has described organisms morphologically indistinguishable from toxoplasma in cases of granulomatous uveitis, but even in these sections the organisms were not numerous and were found on...

Automatic morphometry of nerve histological sections.

A method for the automatic segmentation, recognition and measurement of neuronal myelinated fibers in nerve histological sections is presented. In this method, the fiber parameters i.e. perimeter, area, position of the fiber and myelin sheath thickness are automatically computed. Obliquity of the sections may be taken into account. First, the image is thresholded to provide a coarse classificat...

Correlation between Micro-ct Sections and Histological Sections of Mouse Skull Defects Implanted with Engineered Cartilage.

One advantage of using cartilage to replace/repair bone is that the implant disappears as bone is formed by endochondral ossification. Previously, we showed that cartilage spheroids, grown in a rotating bioreactor (Synthecon, Inc.) and implanted into a 2 mm skull defect, contributed to healing of the defect. Skulls with or without implants were subjected to microCT scans. Mineralized regions fr...

Are basophils identifiable in histological sections of cat skin?

Reconstructing protein networks of epithelial differentiation from histological sections

MOTIVATION For systems biology of complex stratified epithelia like human epidermis, it will be of particular importance to reconstruct the spatiotemporal gene and protein networks regulating keratinocyte differentiation and homeostasis. RESULTS Inside the epidermis, the differentiation state of individual keratinocytes is correlated with their respective distance from the connective tissue. ...
