Publications and Research

A prospective observational study was conducted at three ophthalmic clinics to assess the clinical patterns and etiology of uveitis in the Central Asia Republic of Tajikistan. All patients underwent physical and ophthalmologic examinations. Extensive efforts were made to determine the etiology of uveitis, including workups for Behçet's Disease (BD) and Vogt–Koyanagi–Harada (VKH) syndrome. All patients were tested for the presence of HLA-B27. Presence and/or history of tuberculosis and syphilis were ruled out. HSV, CMV, Chlamydia trachomatis and HIV antibody titers were determined by ELISA. Uveitis was diagnosed in 51 patient ages 14 to 60 were with women accounted for 60.8%. …

Complement Expression In The Retina Is Not Influenced By Short-Term Pressure Elevation, Konstantin Astafurov, Cecilia Q. Dong, Lampros Panagis, Gautam Kamtham, Lizhen Ren, Anna Rozenboym, Tarique D. Perera, Jeremy D. Coplan, John Danias

Purpose: To determine whether short-term pressure elevation affects complement gene expression in the retina in vitro and in vivo.

Methods: Muller cell (TR-MUL5) cultures and organotypic retinal cultures from adult mice and monkeys were sub- jected to either 24-h or 72-h of pressure at 0, 15, 30, and 45 mmHg above ambient. C57BL/6 mice were subjected to microbead-induced intraocular pressure (IOP) elevation for 7 days. RNA and protein were extracted and used for analysis of expression levels of complement component genes and complement component 1, q subcomponent (C1q) and comple- ment factor H (CFH) immunoblotting. …

Transcranial Magnetic Stimulation Of The Prefrontal Cortex Delays Contralateral Endogenous Saccades, Tony Ro, Avishai Henik, Liana Machado, Robert D. Rafal

Publications and Research

The contributions of the superior prefrontal cortex (SPFC) and the superior parietal lobule (SPL) in generating voluntary endogenous and reflexive visually guided saccades were investigated using transcranial magnetic stimulation (TMS). Subjects made choice saccades to the left or right visual field in response to a central arrowhead (endogenous go signal) or a peripheral asterisk (exogenous go signal) that were presented along with a single TMS pulse at varying temporal intervals. TMS over the SPFC increased latencies for saccades made in response to an endogenous go signal toward the contralateral hemifield. No effects were observed when the go signal was exogenous …
