Outbreaks causing mass mortalities have been observed in the golden grey mullet (Liza auratus) population in southern coastal area of the Caspian Sea since 2002. The clinical signs include neurological abnormalities, such as erratic swimming behavior, spiral swimming, belly-up at rest and over inflation of the swim bladder. Three hundred and twelve samples of moribund fish with sizes that range...

Background & Aims: Age-related macular degeneration (ARMD) is one of the common retina disorders that can lead to loss of vision by increase in age. In this study, the efficacy of a non-invasive ultrasound technique for the evaluation of alastic properties of eye in the diagnosis of ARMD has been evaluated. Methods: For estimation of the elastic modulus of eye, spatial loading system designed a...

previous evidence has shown that the number of l and m cones in retina varies significantly between subjects. however, it is not clear how the variation of l/m ratio changes the behavioral performance of the subject. a model of transformation of data from retina to visual cortex for evaluation of various l/m cones ratios is presented. while l/m cone ratios close to 1 brings the best performance...

Vitreoretinal surgery is challenging even for expert surgeons owing to the delicate target tissues and diminutive workspace in retina. In addition improved dexterity accuracy, robot assistance allows (partial) task automation. this work, we propose a strategy automate motion of light guide with respect surgical instrument. This automation instrument's shadow always be inside microscopic view, w...
