Association of Nasal Septum Area and Deviation with Anteroposterior Maxillary Position and Facial Skeletal Asymmetries
… septum area was tested for association with anteroposterior position of the maxilla. The area of the cartilaginous nasal septum was calculated using the CBCT scan and a lateral cephalometric radiograph was created from the CBCT to evaluate the anteroposterior position of the maxilla. Second, …

AP Relationship of the Maxillary Central Incisors to the Forehead in Adult Korean Females
Objectives: To evaluate and compare the anteroposterior relationship of the maxillary central incisors to the forehead in adult Korean females with harmonious profiles and in adult Korean female orthodontic patients. Methods: Ninety five photographic images of adult Korean females with good facial …

Regulation of morphogen signalling during neural patterning in the Xenopus embryo
… A biphasic model for the role of XSufu in anteroposterior patterning of the neural plate is presented suggesting that XSufu suppresses anterior Gli and posterior β-catenin transcription factors in a dose-dependent manner. Then we introduce the secreted serine protease xHtrA1 as feedforward …

Craniofacial morphology and the consequences of intentional cranial deformation among prehistoric Andean populations
… practice of cranial deformation (annular and anteroposterior), and its effects on 27 craniometric measurements and biodistances among 350 prehistoric crania from the Azapa valley of northern Chile. Included among these 27 measurements were nine facial measurements previously considered to be …

CBCT Analysis of the Pharynx: Effects of Age and Sex
… pharyngeal volume, cross-sectional areas, and anteroposterior and mediolateral dimensions. Analysis of covariance was used to test for sex and age effects (range: 5 to 81 years). Age changes are interpreted with caution since the data are cross-sectional. <strong>Results</strong>: Sexual …

Biomechanical Determinants of Altered Knee Joint Loads After 18 Months of Intensive Weight Loss
… force, patellofemoral (PF) compressive force, anteroposterior (AP) shear force, and internal knee abduction moment (iKAM)). We also hypothesized that gait speed, knee flexion angle, and internal knee extensor moment would display positive associations with each of the knee force outcome …

Predictive balance control during backward walking and effects of a haptic input based intervention on predictive balance control during walking
… compared to forward walking. Step length and anteroposterior margin of stability were significantly reduced, and step width and mediolateral margin of stability were significantly increased during backward walking compared to forward walking. Backward walking was also significantly more …

Radiographic Union Score for Tibia (RUST) scoring system in adult diaphyseal femoral fractures treated with intramedullary nailing: an assessment of interobserver and intraobserver reliability
… Patients and Methods A total of 60 sets of anteroposterior (AP) and lateral radiographs of diaphyseal femoral fractures treated by reamed IM nailing were randomly selected from a prospectively collected database. The 60 sets of radiographs were then scored by three reviewers using the RUST …

The Effectiveness of Tipback Mechanics for Correction of Class II Malocclusion
… of root uprighting. There was no significant anteroposterior growth of the mandible during the intervention period. A power analysis of the initial data indicated a minimum sample size of 10 subjects required for a future clinical trial. The results of this pilot study have confirmed the …

The Mechanics and Influence of the Foot-Ground Interaction During Bipedal Walking
… walking is closely related to the magnitude of anteroposterior ground reaction forces as well as the time duration of foot-ground contact during the gait cycle. These results highlight the importance of exploring habitual human locomotion outside of the confines of the laboratory to fully …
