Fig. 1. A 59-year-old female with parkinsonian multiple system atrophy (MSA-P) with no vertical supranuclear gaze-palsy. A T2weighted image suggests the lateral margin of the posterior tegmentum of the midbrain is ‰at or slightly concave. Note that both superior and inferior colliculi are present in the same plane. Fig. 2. A midsagittal T1-weighted image of the same patient. The horizontal line...

Biomechanical influences on bone structure play an important role in the longevity of bone around an implant. The quantity and direction of applied force influence the implant and cause deformation of the bone. FEA was used to analyze the changes in the bone on loading the implant with orthodontic force in oblique and vertical directions and orthopedic force. The Mini-implants used in the prese...

OBJECTIVE To determine the correspondence between optic disc margins evaluated using disc photography (DP) and optical coherence tomography (OCT). METHODS From May 1, 2005, through November 10, 2005, 17 healthy volunteers (17 eyes) had raster scans (180 frames, 501 samplings per frame) centered on the optic disc taken with stereo-optic DP and high-speed ultrahigh-resolution OCT (hsUHR-OCT). T...

We describe how we use models of mantle dynamics to understand and test the controls and effects of plate tectonics, such as ocean basin volume, magma production and the formation of natural resources. Numerical modeling and geological ground-truthing were incorporated to test the hypothesis that vertical motion of the Australian continental plate, as observed from sediments deposited during a ...

[1] A first‐order process in the growth of continents is the collision and accretion of terranes against continental margins. Collision leads to the formation of a suture zone between the accreted terrane and the former continental margin. New insights on the suturing process are observed from two receiver function transects across the Mesozoic Alaska Range suture zone. Three distinct crustal s...

For this survey, 92 vertically fractured endodontically treated teeth were evaluated clinically and radiographically before and after extraction. The maxillary second premolars (27.2%) and mesial roots of the mandibular molars (24%) were the most fractured teeth. In 67.4% of the teeth, a solitary buccal pocket was present; in 34.8%, a fistula frequently appeared closer to the gingival margin th...

The margin of the temporal visual field lies more than 90° from the line of sight and is critical for detecting incoming threats and for balance and locomotive control. We show (i) contrast sensitivity beyond 70° is higher for moving stimuli than for stationary, and in the outermost region, only moving stimuli are visible; (ii) sensitivity is highest for motion in directions near the vertical a...

angle of the mouth to the ear, and the growth dissected out by scissors, including a liberal margin of subjacent and surrounding healthy tissue. A vertical incision was made from the middle of the transverse cut, and the enlarged sub-maxillary glands removed through it. The wound was then carefully stitched, and a drainage tube inserted through its lower angle. It healed by first intention in e...

[1] Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic C production in ice, and this component must be well understood before useful information can be extracted from C data. We combine cosmic ray scaling and production estimat...

BACKGROUND Markus-Gunn Jaw-winking Phenomenon (MGJW) is a congenital ptosis associated with synkinetic movement of upper lid on masticating movements of jaw. It results from aberrant connection between motor division of trigeminal nerve and oculomotor nerve. OBJECTIVE To investigate the clinical characteristics of MGJW phenomenon and evaluate its surgical outcomes of unilateral levator excisi...
