Tarlov or perineural cysts are lesions of the nerve root most often found in the sacral region. Several authors recommend surgical treatment of symptomatic Tarlov cysts. However, successful surgical treatment is dependent on appropriate patient selection. In this article, we report three cases of a sacral perineural cyst, causing sciatic pain, and emphasize(More)
¶ Herniated intervertebral discs are rare in children and adolescents constituting approximately 1–5% of all patients undergoing surgery for lumbar and lumbosacral intervertebral disc herniation. Preceding traumata and congenital anomalities have been reported as important factors for the pathogenesis of intervertebral disc prolapses in young patients. The(More)
This paper presents a new DSP-oriented code optimization method to enhance performance by exploiting the specific architectural features of digital signal processors. In the proposed method, a source code is translated into the static single assignment form while preserving the high-level information related to the address computation of array accesses. The(More)
Pain is a well recognized feature of Parkinson disease (PD). Like motor fluctuations, pain in PD may fluctuate as ‘non-motor fluctuations’. Subthalamic deep brain stimulation (STN DBS) is an established treatment for motor fluctuations in PD. However, the effect of STN DBS on the pain in PD is only partially investigated. PD patients who were considered for(More)
Large-eddy simulation (LES) seeks to predict the dynamics of spatially filtered turbulent flows. By construction, the LES solution contains only scales of size ≥ ∆, where ∆ denotes some user-chosen length scale of the spatial filter. A large-eddy simulation based on an eddy-viscosity model and a Navier-Stokes simulation differ only in diffusion coefficient.(More)
Interbody fusion after anterior discectomy may lead to acceleration of degenerative changes at adjacent levels. Although the posterior approach preserves the motion segment, decompression of the nerve root is indirect if “hard disc prolaps” is the main cause. Recently, a technique of microsurgical anterior cervical foraminotomy for the treatment of(More)
 Previously, we found that the E5 protein can be expressed in HPV-16 infected precancerous lesions and cervical cancer [4]. In this study, we investigated the presence of sequence variants of E5 in HPV-16 infected tissues. Toward this end, we amplified the E5 gene by polymerase chain reaction from 29 HPV-16 infected tissues including eight normal tissues,(More)
Close control of blood glucose levels significantly reduces vascular complications in Type I diabetes. A control method focusing on the rate of change of blood glucose level is developed to utilize emerging technologies in blood glucose biosensors. The controller developed provides tighter, more optimal control of blood glucose levels, while robustly(More)
