The low power as a feature of a BIST scheme is a significant target due to quality as well as cost related issues. In this paper we examine the testability of multipliers based on Booth encoding and Wallace tree summation of the partial products and we present a methodology for deriving a low power Built In Self Test (BIST) scheme for them. We propose(More)
Epilepsy surgery has been proposed as a safe alternative treatment for intractable epilepsy in children, especially for patients with structural brain abnormalities. We studied 24 consecutive children who underwent surgery for intractable epilepsy. There were 12 males and 12 females. The mean age was 6.5 years. The seizures' duration ranged from 6 months to(More)
Spinal stenosis refers to narrowing of the spinal canal with encroachment of the neural structures by adjacent bone and soft tissue. Surgical treatment usually offers greater pain relief and functional recovery than non-surgical treatment. Nevertheless, neurological complications from decompressive laminectomy have been reported to range between 1% and 33%.(More)
BACKGROUND AND PURPOSE Neuropathologic studies in experimental and human glaucoma have demonstrated degenerative changes in the optic pathway. The purpose of this study was to assess the optic pathway in POAG by using VBM and DTI. MATERIALS AND METHODS Eighteen patients 57.05 ± 11.38 years of age with POAG of 8.30 ± 5.14 years' duration and 18 control(More)
Sudden unexplained/unexpected death (SUDEP) in epilepsy is a major cause of death accounting for 7-17% of the mortality among epileptic patients. Prolongation of QT-interval has been issued as a major mechanism in SUDEP since it is associated with fatal cardiac arrhythmias. This condition may be further precipitated by anti-epileptic treatment. Despite(More)
Among factors regulating the splicing of major importance is serine/arginine protein kinase 1 (SRPK1) that phosphorylates SR splicing factors. SRPK1 is expressed in the mammalian central nervous system in a region- and neuron-specific manner. Based on previous observations that glial cells are practically devoid of SRPK1 and reports showing aberrant(More)
AIM We investigated the angiogenesis and density of newly formed blood vessels in embryonal tumors in relation to Ki-67, bcl-2, p-53 and p-27 expression. METHODS Forty-five children with embryonal tumors were enrolled in the study. Forty patients had a medulloblastoma (MB) and 5 patients had atypical teratoid/rhabdoid tumor (AT/RT). RESULTS In MB, the(More)
