The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Thermosensitive 2-Dg-Loaded Hydrogel Attenuates Periodontitis Via Th17 Suppression

open access: yesInternational Dental Journal
Aim or purpose: To investigate the role of IL-17a in immune regulation during periodontitis and develop a novel localized drug delivery system based on glycolysis inhibition for safer and more effective treatment.

Ageing characteristics of bone indicated by transcriptomic and exosomal proteomic analysis of cortical bone cells

open access: yesJournal of Orthopaedic Surgery and Research, 2019
Background Degenerative changes in the skeleton play an important role in ageing. As the foremost sensors and orchestrators of bone remodelling, osteocytes contribute significantly to the health of the skeleton. Embedded in a mineralized bone matrix, the

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

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.

Antibacterial effects and mechanisms of graphene oxide loaded on TiO2-nanotube-modified ti: an in vitro study

open access: yesBMC Oral Health
Background Peri-implant inflammation is an important factor affecting the success rate of dental implants. Improving the antibacterial performance of implants is an effective method to prevent and treat peri-implant inflammation.

The Quantification of Tooth Displacement [PDF]

open access: yes, 2010
By using reference points from a single pixel marker placed at the center point of the cuspid teeth and the center point on each of the incisor teeth, a polynomial curve was generated as a native curve for each dental arch studied.

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

open access: yesThe Anatomical Record, EarlyView.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Effect of extended tooth contact on the modeling of spur gear transmissions [PDF]

open access: yes
In some gear dynamic models, the effect of tooth flexibility is ignored when the model determines which pairs of teeth are in contact. Deflection of loaded teeth is not introduced until the equations of motion are solved.

On the plastic collapse of horizontal saddle supported storage vessels [PDF]

open access: yes, 2003
The present paper summarises a comprehensive programme of work on collapse loads of horizontal cylindrical saddle supported storage vessels. A programme of tests was conducted on 40 model vessels that included both welded and loose saddles.
