Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

The Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

A histopathological study of various root canal filling materials.

Showa Shigakkai zasshi = The Journal of Showa University Dental Society, 1990
This report compares tissue irritation by a newly developed calcium-based root canal filling material with irritation by previously available materials and evaluates the toxicity of various components in the root canal filling material. Polyethylene tubes filled with root canal filling materials were implanted in rat subcutaneous tissue, enucleated ...

Characterization of the extracellular matrix from human and dog umbilical cords

The Anatomical Record, EarlyView.
Abstract The extracellular matrix is important for maintaining tissue morphogenesis and homeostasis; it can also be used as a biomaterial for the production of biological scaffolds. Particularly, the umbilical cord has shown potential in the production of scaffolds for small‐diameter vessels.

Clinical and radiographic evaluation of pulpectomies using three root canal filling materials: An in-vivo study

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2010
Various root canal filling materials are used to preserve a pulpally involved carious primary tooth. But there is no single material so far available to fulfill all the requirements of an ideal root canal filling material for a primary tooth.
