Brain-derived neurotrophic factor (BDNF) is known to be crucial for the development of peripheral vestibular neurons. However, the maturation profile of the BDNF signal transducing receptor, tyrosine kinase B (TrkB) in functionally activated otolith-related vestibular nuclear neurons of postnatal rats remains unexplored. In the present study, conscious Sprague-Dawley rats (P4 to adult) were sub...

In the mouse retina, horizontal cells form an electrically coupled network and provide feedback signals to photoreceptors and feedforward signals to bipolar cells. Thereby, horizontal cells contribute to gain control at the first visual synapse and to the antagonistic organization of bipolar and ganglion cell receptive fields. However, the nature of horizontal cell output remains a matter of de...

In this paper, by using the exponential convexity property of a barrier function, we propose an infeasible interior-point method for Cartesian P_*(k) horizontal linear complementarity problem over symmetric cones. The method uses Nesterov and Todd full steps, and we prove that the proposed algorithm is well define. The iteration bound coincides with the currently best iteration bound for the Ca...

BACKGROUND Dissociated horizontal deviation is one of several conditions that manifest unequal horizontal deviations depending on which of the 2 eyes is fixating. PURPOSE To describe the reversed fixation test as an essential tool to establish the diagnosis of dissociated horizontal deviation. METHODS Analysis of 4 case scenarios depicting the utility of the reversed fixation test. RESULT...

PURPOSE To report a keratoconus case with bilateral horizontal Vogt's striae. METHOD The clinical findings of the patient and the development of the direction of striae are discussed. RESULTS Vogt's striae, defined as vertical stress lines, are rarely horizontal. One patient with unilateral horizontal stress lines on his left eye has been reported in the literature. Our patient has horizont...
