Radial retroiridal linear pigmentation.
Radial retroiridal pigmented lines found on the peripheral anterior capsule of the lens have been interpreted since their description by Vogt as remnants of the tunica vasculosa retroiridalis (membrana capsulopupillaris). They were found in nearly 5% of adults. A control examination of 1108 children and juveniles failed to reveal a single example. They are therefore thought to be caused by pigm...
متن کاملRadial Projections for Non-Linear Feature Extraction
In this work, two new techniques for non-linear feature extraction are presented. In these techniques, new features are obtained as radial projections of the original measurements. Radial projections are a particular kind of second order transformations that show interesting properties: they capture the local structure of the data and reduce dramatically the number of parameters to estimate fro...
متن کاملHistochemistry of B663 Pigmentation: Ceroid-Like Pigmentation
Since its use was first reported by 8rowne and Hogerzeil in 1962 ('0. /I), 8663, a synthesized phenazine dye, has proven to be an effective drug in the treatment of human leprosy and its use has become worldwide ( 2.7.9 " . 26. 3~. 39. 52. 5.1 ). The most significant and frequent side effect of this compound is an abnormal skin coloration. This can be divided into two types. One is an initial r...
متن کاملOral pigmentation
Change in color of oral mucosa reflects the underlying health status, which is either local or systemic. This color change is due to pigmentation, which may be physiological or pathological. Pigmentation in pathological conditions range from localized anomalies of to potentially life-threatening conditions. Since the dental professionals encounter a number of pigmented lesions in the oral cavit...
متن کاملNon-Linear Analysis of Functionally Graded Sector Plates with Simply Supported Radial Edges Under Transverse Loading
In this study, nonlinear bending of functionally graded (FG) circular sector plates with simply supported radial edges subjected to transverse mechanical loading has been investigated. Based on the first-order shear deformation plate theory with von Karman strain-displacement relations, the nonlinear equilibrium equations of sector plates are obtained. Introducing a stress function and a potent...
