PURPOSE To investigate the relationship between dental, chronological, and cervical vertebral maturation growth in the peak growth period, as well as to study the association between the dental calcification phases and the skeletal maturity stages during the same growth period. METHODS Subjects were selected from orthodontic pre-treatment cohorts consisting of 420 subjects where 255 were iden...

BACKGROUND Association of low cardiac vagal activity and poor outcome is demonstrated in the cardiology setting. This has not been addressed in the postoperative setting. Cardiac vagal motoneurones (CVMs) in the brain stem generate sinus arrhythmia. They may reduce blood pressure (BP) variability ('pressure lability'). An alpha-2 agonist, clonidine, was administered to assess whether cardiac va...

Advances in communication devices and technologies are dramatically expanding our communication capabilities and enabling a wide range of multimedia communication applications. The current approach to develop communication-intensive applications results in products that are fragmented, inflexible and incapable of responding to changing end-users’ communication needs. These limitations have resu...

The present study aimed to provide a version of the Cervical Vertebral Maturation (CVM) method for the detection of the peak in mandibular growth based on the analysis of the second through fourth cervical vertebrae in a single cephalogram. The morphology of the bodies of the second (odontoid process, C2), third (C3), and fourth (C4) cervical vertebrae were analyzed in six consecutive cephalome...

Extracellular recordings were made in the right nucleus ambiguus of urethane-anesthetized rats from 33 neurons that were activated at constant latency from the craniovagal cardiac branch. Their calculated conduction velocities were in the B-fiber range (1.6-13.8 m/s, median 4.2), and most (22/33) were silent. Active units were confirmed as cardiac vagal motoneurons (CVM) by the collision test f...
