Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Catching the Wave: An Exploration of Posterior Pharyngeal Wall Movement in Healthy Swallowing

Laryngoscope Investigative Otolaryngology
Objective(s) Serial pharyngeal constrictor muscle contraction during swallowing can be seen fluoroscopically as a wave of posterior pharyngeal wall (PPW) movement.

Partial cricotracheal resection for paediatric subglottic stenosis: update of the Lausanne experience with 129 cases [PDF]

, 2017
OBJECTIVES Partial cricotracheal resection (PCTR) is widely accepted for treating severe paediatric laryngotracheal stenosis (LTS). However, it remains limited to a few experienced centres.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Swallowing Activity Assessed by Ambulatory Impedance-pH Monitoring Predicts Awake and Asleep Periods at Night [PDF]

, 2018
Introduction: Voluntary muscle activity, including swallowing, decreases during the night. The association between nocturnal awakenings and swallowing activity is under-researched with limited information on the frequency of swallows during awake and ...

Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

The Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.

Clock genes regulate Ca2+ signaling and mitochondrial bioenergetics to inhibit Sjogren's disease

Arthritis &Rheumatology, Accepted Article.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjogren's disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA seq, and mitochondrial activity were used to investigate the effects of ...

Clinical swallowing prognostic indicators in patients with acute ischemic stroke

Arquivos de Neuro-Psiquiatria
A swallowing disorder is present in more than 50% of patients with acute stroke. Objective To identify clinical prognostic indicators of the swallowing function in a population with acute ischemic stroke and to determine prioritization indicators for ...
