Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment
The Anatomical Record, EarlyView.Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

[Nucleolus organizer regions in prostatic intraepithelial neoplasm].
Pathologica, 1991 Using a silver staining technique, Nucleolar Organizer Region-associated proteins (NORs) were evaluated on paraffin sections of 16 resected prostatic adenocarcinomas stage A1. Then 30 histological areas was selected which comprised 6 areas for each grade of Prostatic Intraepithelial Neoplasia: PIN 1, PIN 2, PIN 3, 6 areas of normal glandular prostatic ...
