Studies of mechanisms of feeding behavior are important in a society where aging- and disease-related feeding disorders are increasingly prevalent. It is important to evaluate the clinical relevance of animal models of the disease and the control. Our present study quantifies macaque hyolingual and jaw kinematics around swallowing cycles to determine the extent to which macaque swallowing resembles that of humans. One female and one male adult Macaca mulatta were trained to feed in a primate chair. Videofluoroscopy was used to record kinematics in a sagittal view during natural feeding on solid food, and the kinematics of the hyoid bone, thyroid cartilage, mandibular jaw, and anterior-, middle-, and posterior-tongue...

PURPOSE: Although it is frequently presumed that bulbar muscle degeneration in Amyotrophic Lateral Sclerosis (ALS) is associated with progressive loss of speech motor control, empirical evidence is limited. Furthermore, because speaking rate slows with disease progression and rate manipulations are used to improve intelligibility in ALS, this study sought to (i) determine between and within-group differences in articulatory motor control as a result of speaking rate changes and (ii) identify the strength of association between articulatory motor control and speech impairment severity...

BACKGROUND: The aim of this study was to evaluate osteogenesis ability of CAD/CAM porous zirconia scaffolds enriched with hydroxy apatite used to augment large boney defects in a dog model. METHODS: Surgical defects were made bilaterally on the lower jaw of 12 Beagle dogs. Cone beam CT images were used to create three dimensional images of the healed defects. Porous zirconia scaffolds were fabricated by milling custom made CAD/CAM blocks into the desired shape. After sintering, the pores of half of the scaffolds were filled with a nano-hydroxy apatite (HA) powder while the other half served as control...

The shape of the dental arcade and canine size distinguish extant humans from all apes. Humans are characterized by a parabolic arcade with short postcanine tooth rows and small canines, whereas apes have long, U-shaped arcades with large canines. The evolutionary and biomechanical mechanisms underlying arcade shape differences between and within groups are not well understood. It is unclear, for example, whether evolutionary changes in the covariation among modules comprising the upper and lower jaws are the cause and/or consequence of different arcade shapes...

BACKGROUND: It is generally understood that cancer patients are at an increased risk for osteoporosis. Additionally, recent studies have suggested a shared pathophysiological mechanism between the development of cancer and osteoporosis. The purpose of this investigation was to investigate whether low bone mineral density is associated with cancer risk. METHODS: We enrolled 8780 subjects who underwent dual-energy X-ray absorptiometry (DXA) and cancer screening from January 1, 2008-December 31, 2012 from a cohort selected from Chang Gung Health Care Center in Taiwan...

BACKGROUND AND OBJECTIVE: Anemia is a common health problem worldwide. This problem is most commonly faced by 18 to 25 years of females. Medical students especially female hostelites poses high risk of anemia because of their poor eating habits, breakfast skipping, long schedule in college, burden of medical studies, clinical postings, and extra-curricular activities. Therefore the current study was designed to determine the hemoglobin status in young female medical students. We also elucidate its association with BMI...

Development of dental abnormalities due to improper occlusal wear is common among modern domestic horses. This phenomenon often is attributed to jaw conformation. Rostral mandibular hooks may develop in horses with underjet or mandibular prognathism, a condition where the lower jaw protrudes forward, beyond the upper jaw. Less abrasive diet, free of phytoliths and matrix-like plant fibers, also may promote enamel and focal overgrowths of equine dentition. Here we report a rostral mandibular hook in a lower premolar tooth of a medieval horse, found in a spring deposit in Levänluhta, Osthrobothnia, Finland...

OBJECTIVE: The purpose of this study was to investigate how the opening direction of the mental foramen (MF) changes with age in a Japanese population using multi-detector computed tomography (MDCT). METHODS: Post-mortem MDCT scans of 121 Japanese subjects (66 males and 55 females) were carried out where all subjects possessed at least twenty teeth, including molar teeth, in the upper and lower jaws. Two angles of the mental foramen opening were measured, namely the superior-inferior angle in the coronal plane and anterior-posterior angle in the transverse plane, on the CT reconstructed images...

Although the establishment of trophic ecomorphology in living crocodylians can contribute to estimating feeding habits of extinct large aquatic reptiles, assessment of ecomorphological traits other than the snout shape has scarcely been conducted in crocodylians. Here, I tested the validity of the proposed trophic ecomorphological traits in crocodylians by examining the correlation between those traits and the snout shape (an established trophic ecomorphology), using 10 non-alligatoroid crocodylian species with a wide range of snout shape...

Cleaning, a dietary strategy in which ectoparasites or mucous are removed and consumed off other taxa, is performed facultatively or obligately in a variety of species. We explored whether species in the Labridae (wrasses, parrotfishes) of varying ecological specialization employ similar mechanisms of prey capture. In investigating feeding on attached prey among juveniles of 19 species of wrasses, we found that patterns of biting in wrasses are influenced by the interaction between the maxilla and a feature of the premaxilla which we term the maxillary crest...

Mid-face augmentation via a Le Fort I osteotomy is a commonly performed operation. Advancement of the upper jaw and associated structures (nose, lower cheek areas) can certainly improve function as well as facial aesthetics and harmony. Often, in patients with severe mid-face deficiency, hypoplasia of the maxilla extends all the way up to the infraorbital rims. The receding infraorbital rim contributes to the negative vector of the globes. In patients with this level of mid-face hypoplasia, while advancing the maxilla at the Le Fort I level satisfies all of the requirements for orthognathic surgery, the deficient infraorbital rim remains unchanged and can actually accentuate the negative vector of the globes...

Disseminated intravascular coagulation (DIC) is a major pathophysiological mechanism of sepsis and greatly increases the risk of death in septic patients. Disseminated intravascular coagulation is a complex physiological phenomenon that involves inappropriate activation of coagulation, inflammation, and endothelial processes. The purpose of this study was to analyze the levels of inflammatory cytokines in the plasma of patients with DIC in order to compare the measured levels with those from healthy individuals, draw correlations, and provide a basis for further biomarker panel development...

Selection by consumers has led to the evolution of a vast array of defenses in animals and plants. These defenses include physical structures, behaviors, and chemical signals that mediate interactions with predators. Some of the strangest defensive structures in nature are the globiferous pedicellariae of the echinoderms. These are small venomous appendages with jaws and teeth that cover the test of many sea urchins and sea stars. In this study, we report a unique use of these defensive structures by the collector sea urchin Tripneustes gratilla...
