Tonic stimuli can elicit rhythmic responses. The neural circuit underlying Aplysia californica consummatory feeding was used to examine how a maintained stimulus elicits repetitive, rhythmic movements. The command-like cerebral-buccal interneuron 2 (CBI-2) is excited by tonic food stimuli but initiates rhythmic consummatory responses by exciting only protraction-phase neurons, which then excite...

OBJECTIVE To compare the amount of anchorage loss of the maxillary posterior teeth and amount of retraction of the maxillary anterior teeth between en masse retraction and two-step retraction of the anterior teeth. MATERIALS AND METHODS The sample consisted of 30 female adult patients with Class I malocclusion and lip protrusion who needed maximum posterior anchorage. The sample was subdivide...

background: to provide a point of reference to study the epidemiology and clin-ical expression of canine babesiosis in china. methods: a total of 30 dogs infected with canine babesiosis were evaluated by mean of clinical history, physical examination, hematological, restriction fragment length polymorphism of pcr products (pcr-rflp) and sequencing analysis. result: the most prevalent clinical a...

Swing-leg retraction, the backward rotation of the swing leg just prior to ground contact, is observed in human locomotion. While several advantages of swingleg retraction, like gait stability and perturbation rejection, are shown by conceptual models, there is currently very little experimental data on swing-leg retraction in human motion. In this paper, kinematic data for twenty-eight subject...

Abstract Introduction: Maxillary canines commonly have an ectopic eruption. This study aimed to assess the factors related to the ectopic maxillary permanent canines. Materials and Methods:This was a descriptive cross-sectional study of 1357 panoramic radiographs from patients 8 to 13 years old. The radiography was excluded if the patient had any developmental disease or if the panoramic im...
