BACKGROUND Though elastic fibers are as important as collagen fibers in interpretation of the histopathologic findings, it is impossible to observe them on the hematoxylin & eosin (H&E) stained specimen. OBJECTIVE Characterizing eosin fluorescence emitted by elastic fibers in H&E stained specimens. METHODS Normal skin tissue sections were stained in 4 different ways (unstained, hematoxylin ...

The structural arrangement of elastic fibers in the splenic capsule from 16 human cadavers ranging in age from 1 month to 76 years was studied by histologic sections stained with selective methods for elastin. In infants the elastic fibers of the splenic capsule were homogeneously intermingled with collagen fibers, an arrangement that stabilizes the capsule during spleen growth and enlargement....

In order to evaluate age related changes of the elastic fiber system in the interfoveolar ligament, we studied the deep inguinal ring from 33 male cadavers aged from stillborn to 76 years. Selective and alternated staining methods for elastic fibers were performed to differentiate oxytalan, elaunin, and mature elastic fibers. We confirmed quantitative changes of the elastic fiber system with ag...

background: the differences between marginal gingiva and interdental papilla may be due to variation in the molecular composition of these two different anatomical structures. the aim of this study was to evaluate the staining intensity of fibronectin in human marginal gingiva and interdental papilla. materials and methods: in a prospective analytical study, 16 healthy subjects needing crown le...

Introduction: Knowledge of the structural features of the vocal fold and the ventricular fold may help to understand the phonation process, and consequently may facilitate the use of the ventricular fold in phonation after laryngeal damage. Objective: To compare the histology and the distribution of collagen and elastic fibers between the ventricular folds and the vocal folds. Methods: Hemilari...

Elastic fibers in the dermis play an important role in skin elasticity. The desmosine crosslinking structure constructed of lysyl oxidase (LOX) in elastic fibers contributes to elasticity, while elastic fibers are primarily degraded by one of the matrix metalloproteinases (MMPs), MMP-12. We investigated the gender differences and diurnal variation of these enzymes. Gender-based differences in L...

The present paper offers a meso-scale numerical model to investigate the effects of random distribution of aggregate particles and steel fibers on the elastic modulus of Steel Fiber Reinforced Concrete (SFRC). Meso-scale model distinctively models coarse aggregate, cementitious mortar, and Interfacial Transition Zone (ITZ) between aggregate, mortar, and steel fibers with their respective materi...

In the present study the age-related changes of the striated muscle elastic fiber system were investigated in the diaphragm and rectus abdominis muscles of 1-, 4-, 8- and 18-month-old rats. The activation patterns of these muscles differ in that the diaphragm is regularly mobilized tens of times every minute during the entire life of the animal whereas the rectus abdominis, although mobilized i...
