Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Characterizing masticatory motion of dogs using optical and electromagnetic motion tracking

open access: yesFrontiers in Veterinary Science
IntroductionAccurate knowledge of masticatory motion across a variety of food materials is essential for ex-vivo testing and simulation of the food-teeth interaction.

Characterization of mesostructure of natural rubber [PDF]

open access: yes, 2017
To study NR mesostructure (macromolecular structure + aggregates or gels) (Figure 1), the NR sample is placed in a good solvent of polyisoprene (cyclohexane, toluene or tetrahydrofuran).

Evaluation of IHH, PTCH1, and SMO protein immunohistochemistry in the human mandibular condyle at fetal stages from 30 to 80 mm greatest length

open access: yesThe Anatomical Record, EarlyView.
Abstract This study evaluated the morphogenesis of the temporomandibular joint (TMJ) in human fetuses during the third month of gestation through the analysis of immunohistochemistry for the proteins Indian Hedgehog (IHH), Patched‐1 (PTCH1), and Smoothened (SMO).

Dietary Adaptations and Intra- and Interspecific Variation in Dental Occlusal Shape in Hominin and Non-hominin Primates [PDF]

open access: yes, 2016
Dental morphology and tooth shape have been used to recreate the dietary adaptations for extinct species, and thus dental variation can provide information on the relationship between fossil species and their paleoenvironments.

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Ingestive Behavior and Body Development of Backgrounded Heifers From Three Genotypes in the Brazilian Pantanal

open access: yesAnimal Research and One Health, EarlyView.
Nelore (N) and Nelore × Pantaneiro (NP) heifers exhibited similar grazing times, which were higher compared with Nelore × Angus (NA) heifers. Nelore heifers showed higher wither height and hip height values compared with NP heifers. The average values for NA heifers did not differ from the other genotypes. It was observed that chest depth, heart girth,

Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

open access: yesAnimal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market
