The new method presented in this study was directly based on the consideration that ophthalmic arterial Doppler signals are chaotic signals. This consideration was tested successfully using the nonlinear dynamics tools, like the computation of Lyapunov exponents. Multilayer perceptron neural network (MLPNN) architecture was formulated and used as a basis for determining variabilities such as st...

Background Behcet’s disease (BD) is an auto-inflammatory disorder, characterized by recurrent aphthous stomatitis, genital ulcers, uveitis, erythema nodosum and other numerous mucocutaneous, gastrointestinal, neurological, vascular manifestations. Despite many biomarkers (anti-lysozyme, serum endocan, alpha 1-acid glycoprotein (AGP)) have been investigated for evaluating activity predicting sev...

Behcet’s disease is a multisystem inflammatory disorder of unknown origin, characterized by recurrent oral and genital ulcerations, ocular and cutaneous lesions, arthritis, central nervous system and vascular disease. There is no pathognomanic laboratory test, but there are clinical criteria to assist in establishing the diagnosis. There are only a few study about the laryngeal manifestation of...
