OBJECTIVE Deep brain stimulation has been used in the treatment of refractory obsessive-compulsive disorder (OCD). Our principal objective was to determine the safety and effectiveness of deep brain stimulation of the inferior thalamic peduncle in the treatment of refractory OCD. METHODS An open protocol was performed from March 2003 to April 2007 in 5(More)
PURPOSE Our aim was to evaluate the safety and efficacy of electrical stimulation of the hippocampus in a long-term follow-up study, as well as its impact on memory performance in the treatment of patients with refractory mesial temporal lobe epilepsy. METHODS Nine patients were included. All had refractory partial complex seizures, some with secondary(More)
Parkinson's disease is a movement disorder whose principal symptoms are tremor, rigidity, bradykinesia and postural instability. Initially, drugs like L: -dopa or dopaminergic agonists are able to control these symptoms, but with the progress of the disease these drugs become less effective. Previous studies have reported that repetitive transcranial(More)
We report two cases of chronic therapeutic stimulation of epileptic foci localized in motor areas. Case 1 is an adolescent with supplementary motor area seizures whose intracranial recordings showed a right SMA focus. Case 2 is a female teenager with primary motor seizures originating in the right motor cortex in the hand area as shown by her intracranial(More)
The Center for Robot-Assisted Search and Rescue (CRASAR®) deployed the custom Sea-RAI man-portable unmanned surface vehicle and two commercially available underwater vehicles (the autonomous YSI EcoMapper and the tethered VideoRay) for inspection of the Rollover Pass bridge in the Bolivar peninsula of Texas in the aftermath of Hurricane Ike.

The 5-hydroxytryptamine-1A (5-HT1A) receptors are known to be involved in the inhibition of seizures in epilepsy. Moreover, studies propose a role for the 5-HT1A receptor in memory function; it is believed that the higher density of this receptor in the hippocampus plays an important role in its regulation. Positron emission tomography (PET) studies in(More)
This report describes research results from the first year of a three-year study focused on the use of recycled asphalt pavement (RAP) and crushed concrete (CC) as backfill for mechanically stabilized earth (MSE) walls. The design procedures for MSE walls are reviewed. The current Texas Department of Transportation (TxDOT) and Federal Highway Administration(More)
Significant research has been performed on glass fiber-reinforced polymer (GFRP) concrete reinforcement. This research has shown that GFRP reinforcement exhibits high strengths, is lightweight, can decrease time of construction, and is corrosion resistant. Regarding the corrosion resistance, research has shown that the chemical reactions that occur in GFRP(More)
