Effects of viewing distance on the responses of vestibular neurons to combined angular and linear vestibular stimulation. The firing behavior of 59 horizontal canal-related secondary vestibular neurons was studied in alert squirrel monkeys during the combined angular and linear vestibuloocular reflex (CVOR). The CVOR was evoked by positioning the animal's head 20 cm in front of, or behind, the ...

Pelvic bone tumor resection is challenging due to complex geometry, limited visibility, and restricted workspace. Accurate resection including a safe margin is required to decrease the risk of local recurrence. This clinical study reports 11 cases of pelvic bone tumor resected by using patient-specific instruments. Magnetic resonance imaging was used to delineate the tumor and computerized tomo...

A new species of the pardaliscid amphipod, Nicippe recticaudata, from off Cape Toi, Japan, is named and described. This is the first record of Nicippe Bruzelius, 1859 from the western Pacific coast of the Japanese archipelago. Additionally, nucleotide sequences of nuclear 28S ribosomal RNA and histone H3 as well as mitochondrial cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA from th...

Background. The margin status is an important prognosticator for the survival of patients with tongue cancer. Although a positive margin is associated with a poor prognosis, those with clear margins do not always have good clinical outcomes. Methods. We investigated the margin status, pattern of tumor invasion (POI), and tumor satellite distance (TSD) in 119 freshly treated tongue cancers and a...

lead as non-essential metal, is known the source of toxicity and impacts on the environment and humans. the goal of recent paper is to determine the pb concentration of road and road margin dust of ghamishlu wildlife refuge in isfahan province with an area about 120,000 hectares surrounded by four main roads. traffic load in the southern freeway have been reported as about 3600-19000 cars/day. ...

Three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. Many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. This manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated...

Accurate assessment of ocular alignment in monkeys is difficult because typical clinical methods require extensive cooperation by the subject or provide only a rough estimate of the misalignment. Recently, Brodie derived a geometrical model for determining the Hirschberg ratio in humans, and validated it photographically. In this study, we have applied these procedures in order to determine cor...

OBJECTIVE To examine horizontal saccades in elderly subjects with falling history; prior extensive screening was done to recruit subjects with falling history in the absence of pathology. METHODS Twelve elderly with falling history were tested. Two testing conditions were used: the gap (fixation target extinguishes prior to target onset) and the overlap (fixation stays on after target onset) ...
