Traditionally, ocular surface cytology is studied with techniques such as spatula technology and brush technology. The problem with these techniques is that they may induce traumatic lesions on the surface of the eye, which can progress to scarring, eyelid deformity, limbal stem cell deficiency and in some cases, cause great discomfort to the subject. To avoid these clinical problems, impressio...

Ocular manifestations in Systemic Lupus Erythematosus (SLE) are relatively frequent, with a major prevalence of the Keratoconjunctivitis sicca. Nevertheless, the appearance of unilateral exophthalmos secondary to orbital pseudotumor in patients with SLE is extremely rare(1-7), and on occasion it can be refractory to conventional pharmacological treatment (glucocorticoids and immunosuppressants)...

The microbial reductive dechlorination kinetics of pentachloroaniline (PCA) and less chlorinated anilines (CAs) were investigated with a mixed, fermentative/ methanogenic culture. Batch dechlorination assays were performed with all available CAs at an initial concentration of 3 microM, and an incubation temperature of 22 degrees C. Dechlorination of PCA, two tetrachloroanilines (2,3,4,5- and 2,...

PURPOSE To evaluate the effectiveness and safety of accelerated corneal collagen cross-linking (ACXL) in patients below 14 years of age with progressive keratoconus. MATERIALS AND METHODS Thirty eyes of 18 patients with established progressive keratoconus underwent preoperative and postoperative visual acuity assessment, topography, and specular microscopy prior to ACXL and were followed up f...

Proof of Theorem 5 (2). We will begin by constructing from our set, C′, a new set, S, of clusters which are difficult to distinguish in the sense that the Bayes risk for the uniform prior over those in the alternative is bounded away from 0. Enumerate C′ such that C′ = {Ci} ′| i=1. We will build S by unioning k elements of C′, then draw S, S′ uniformly from S. Specifically, let k = b √ |C′|c (r...

K-complexes and sleep spindles often grouped together characterize the second stage of NREM sleep and interest has been raised on a possible interaction of their underlying mechanisms. The reported inhibition of spindles power for about 15 seconds following evoked K-complexes has implications on their role in arousal. Our objective was to assess this inhibition following spontaneous K-complexes...
