R‐spondins/Lgrs expression in tooth development

, 2014
Background: Tooth development is highly regulated in mammals and it is regulated by networks of signaling pathways (e. g. Tnf, Wnt, Shh, Fgf and Bmp) whose activities are controlled by the balance between ligands, activators, inhibitors and receptors ...

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Advances in amino acid metabolism in bone remodeling and osteoporosis

Kouqiang hemian waike zazhi
Bone is a metabolically active organ that undergoes continuous bone remodeling throughout life to maintain bone homeostasis. Amino acids are the basic units of proteins, which play an important role in the regulation of material metabolism and ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Osteogenic mechanism of chlorogenic acid and its application in clinical practice

Frontiers in Pharmacology
Natural polyphenols may have a role in counteracting oxidative stress, which is associated with aging and several bone-related diseases. Chlorogenic acid (CGA) is a naturally occurring polyphenolic compound formed by the esterification of caffeic and ...

Semaphorin Signalling in Neuronal and Vascular Development in the Tooth

, 2016
Background: The tooth is a well-established model in which to study molecular signaling that regulates organ morphogenesis. Previously, organ-specific innervation of the tooth and its molecular regulation has, to some extent, been investigated.

The effects of smoothies on enamel erosion: an in situ study [PDF]

, 2012
Aims: To measure, in vitro, the pH and titratable acidity (TA) of various soft drinks and to assess the effect of smoothies on erosive tooth surface loss of enamel following a 21-day pH cycling protocol using an in situ model. Methods: The inherent pH of

The relationship between form and function of the carnivore mandible

The 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 ...
