BACKGROUND To compare peripapillary choroidal thickness measurements between normal and normal-tension glaucoma eyes. METHODS Cross-sectional comparative study. 50 normal and 52 normal-tension glaucoma subjects were enrolled in the study. Peripapillary choroidal thickness was measured with spectral-domain optical coherence tomography and enhanced depth imaging. After obtaining circular B-scan...

background: the purpose of this study was to create biomaterial scaffolds like platelet-rich plasma (prp) and platelet-rich fibrin (prf) containing stromal cell-derived factor-1 (sdf1) as a chemokine to induce hyaline cartilage regeneration of rabbit knee in a full thickness defect. methods: we created a full thickness defect in the trochlear groove of thirty-six bilateral knees of eighteen mat...

OBJECTIVE To describe the associations between age, knee cartilage morphology, and bone size in adults. METHODS A cross sectional convenience sample of 372 male and female subjects (mean age 45 years, range 26-61) was studied. Knee measures included a cartilage defect five site score (0-4 respectively) and prevalence (defect score of > or =2 at any site), cartilage volume and thickness, and b...

The application of low-frequency acoustic methods for nondestructive testing has a very long history, probably originating with a simple tap technique. These techniques have been successfully applied to a variety of materials and are widely used for the assessment of the quality of bonded sheet metals. They have also proved useful in the NDE of composite materials, particularly honeycomb panels...

PURPOSE To evaluate spectral-domain optical coherence tomography (OCT) findings based on preferential hyperacuity perimeter (PHP) in patients after idiopathic epiretinal membrane surgery. METHODS Forty eyes of 40 patients undergoing surgery for idiopathic epiretinal membrane were included in the study. The best-corrected visual acuity, PHP, Amsler grid test, and OCT were assessed 3 months aft...

OBJECTIVE To evaluate the accuracy of antenatal sonographic measurement of lower uterine segment (LUS) thickness in the prediction of risk of uterine rupture during a trial of labor (TOL) in women with a previous Cesarean section (CS). METHODS PubMed and EMBASE were searched to identify articles published on the subject of sonographic LUS measurement and occurrence of a uterine defect after d...
