The oldest known snakes from the Middle Jurassic-Lower Cretaceous provide insights on snake evolution [PDF]
, 2015 The previous oldest known fossil snakes date from ∼100 million year old sediments (Upper Cretaceous) and are both morphologically and phylogenetically diverse, indicating that snakes underwent a much earlier origin and adaptive radiation.

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Immunohistochemical Expression of Matrix Metalloprotease-2 and Matrix Metalloprotease-9 in the Disks of Patients with Temporomandibular Joint Dysfunction [PDF]
, 2015 Purpose Matrix metalloproteases (MMPs) are tissue-remodeling enzymes that function during the remodeling process, such as in immune-inflammatory diseases.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus
The Anatomical Record, EarlyView.The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

The 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

Revista Facultad de Odontología Universidad de Antioquia, 2009 Maxilla-Facial trauma is the main etiologic factor in jaws and facial fractures. In children, mandibular fractures are one of the main reasons of facial and developmental deformities because they can affect the main facial bony structures.

Expression of MMP-13 in Human Temporomandibular Joint Disc Derangement and Osteoarthritis [PDF]
, 2017 Objective: MMP-13 performs digestion of collagen, which is a primary component of the temporomandibular joint (TMJ) articular disc. This study evaluated the expression of MMP-13 in patients with anterior disc displacement with (ADDwR) and without ...

The Anatomical Record, EarlyView.Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.
