The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

The cheek-to-cheek diameter in the ultrasonographic assessment of fetal growth

open access: yesAmerican Journal of Obstetrics and Gynecology, 1991
Deviations from normal growth modify the amounts of adipose tissue and muscle mass in the adult and the fetus. As an index of the amount of adipose tissue in the fetus, the cheek-to-cheek diameter obtained on an ultrasonographic coronal view of the face at the level of the nostrils and lips was evaluated. Two hundred thirty-four singleton uncomplicated,

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Fetal cheek-to-cheek diameter in the prediction of mode of delivery

open access: yesAmerican Journal of Obstetrics and Gynecology, 2005
The purpose of this study was to assess sonographic fetal cheek-to-cheek diameter (CCD) in predicting mode of delivery.Two hundred sixty-four patients were considered in 2 parts. First, a retrospective analysis of 214 patients entered into a birth weight (BW) study. Measurements of the CCD, biparietal diameter (BPD), and BW, as well as labor data, were
