Morphological diversity of saber‐tooth upper canines and its functional implications

The Anatomical Record, EarlyView.
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

A companion to the preclinical common data elements and case report forms for in vivo rodent neuroimaging: A report of the TASK3‐WG3 Neuroimaging Working Group of the ILAE/AES Joint Translational Task Force

Epilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force established the TASK3 working groups to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.

Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

The Anatomical Record, EarlyView.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho

Use of the passive lower lingual arch in the management of anterior mandibular crowding in the mixed dentition [PDF]

, 2013
Leeway space preservation in the mixed dentition is a well-documented method of space management. In the mandibular arch it may be saved for utilization in the correction of minor anterior crowding by the placement of a passive lower lingual arch (LLA ...

Mesiodistal crown diameters and tooth size discrepancy of permanent dentition in thalassemic patients

Journal of Clinical and Experimental Dentistry, 2013
Objectives: To provide a description of mesiodistal crown diameters (MD) and tooth-size discrepancy (TSD) of the permanent dentition in patients with thalassemia major (TM) and to compare the results with those of unaffected control group.

Hypercanines: Not just for sabertooths

The Anatomical Record, EarlyView.
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...
