Aims: To study the effect of axial length on the hypotensive effect of latanoprost in primary open angle glaucoma (POAG) in a prospective, observational study. Methods: The authors measured axial length and baseline intraocular pressure (IOP) of 109 eyes with POAG, and then repeated the IOP measurements at 1, 3, and 6 months after starting treatment with latanoprost. Results: The mean IOP level...

STUDY DESIGN Clinical study. PURPOSE The dimensions of the working zone for endoscopic lumbar discectomy should be evaluated by preoperative magnetic resonance images. The aim of this study was to analyze the angle of the roots, root area, and foraminal area. OVERVIEW OF LITERATURE Few studies have reported on the triangular working zone during transforaminal endoscopic lumbar discectomy. M...
In this paper, a new type of steel-concrete composite member, concrete-filled core steel tube with outer angle steel plank reinforced concrete stub column, is proposed and a series of nonlinear 3D(three-dimensional) full-range numerical calculations under axial compression are carried out, some important factors are analyzed, such as the strength of the concrete, the steel tube and the angle st...
PURPOSE To investigate the effect of axial length (AL) on the structure-function relationship between retinal nerve fiber layer (RNFL) thickness measurements and visual field (VF) sensitivity measured with Goldmann III and V. METHOD There were 85 eyes of 85 patients with primary open angle glaucoma included in the current study. Optical coherence tomography and VF (Humphrey Field Analyzer 24-...
BACKGROUND Preserving the C7 spinous process during cervical laminoplasty has been reported to prevent axial symptom. Some patients underwent laminectomy and fixation developed the symptom. The objective of this article was to investigate whether axial symptom can be reduced by preserving the C7 spinous process during cervical laminectomy and fixation with lateral mass screw. METHODS Between ...
Deflection of protons under axial channeling in a silicon crystal bent along the <111> axis was observed on experiment with 400-GeV protons at the CERN Super Proton Synchrotron. The deflection efficiency due to axial channeling of protons for the crystal with the bend angle 50 μrad was about 30 %. Axial channeling deflection occurred by means of doughnut scattering and hyper-channeling, this la...
ABSTRACT: It's been more than a century that third molar has drown the attention of orthodontists . This attention has been based on two main reasons: 1- The probable role of third molar in making late crowding or Recrowding of lower anterior teeth 2- Evaluation of causative factors and prediction of impaction of this tooth and orthodontic 's help to prevention of problems caused by this too...
PURPOSE To investigate the utility of the Corneal Visualization Scheimpflug Technology instrument (CST) to assess the progression of visual field (VF) damage in primary open angle glaucoma patients. METHOD A total of 75 eyes from 111 patients with primary open-angle glaucoma were investigated. All patients underwent at least nine VF measurements with the Humphrey Field Analyzer, CST measureme...
The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...
