While free radicals and inflammation constitute major routes of neuronal injury occurring in amyotrophic lateral sclerosis (ALS), neither antioxidants nor non-steroidal anti-inflammatory drugs have shown significant efficacy in human clinical trials. We examined the possibility that concurrent blockade of free radicals and prostaglandin E(2)(More)
—In this paper, we investigate the resource allocation in a differentially modulated relay network. In addition to the energy optimization, we also consider location optimization to minimize the average symbol error rate (SER). The closed-form solution is derived for the single-relay case, and formulas allowing numerical search are provided for(More)
—The optimum resource allocation is an important method to improve the error performance and energy efficiency of wireless relay networks. In this paper, we consider the resource allocation as a two-dimensional optimization problem; that is, the energy optimization and the location optimization. Differential modulation which bypasses the channel estimation(More)

—In vehicular communications, the channel estimation is critical to compensate signal distortion due to wireless channel in high mobility scenario. To improve the error performance of vehicular communications, we proposed the midamble-based channel estimation scheme [12]. Based on the proposed scheme, we investigate the effect of midamble insertion on the(More)
The aim of this study was to evaluate the relationship of serum reproductive hormone levels with cognitive function and negative symptoms in schizophrenic women during the follicular phase of the menstrual cycle. Thirty-five women with chronic schizophrenia who had minimal positive symptoms participated in this study. We evaluated the correlation of serum(More)
Objective. The purpose of this investigation was to assess the cognitive effects of adjuvant hormone replacement therapy (HRT) when used to treat premenopausal women with chronic schizophrenia using an 8-week, double-blind, placebo-controlled, randomized trial. Method. Women of childbearing age with chronic schizophrenia were recruited and randomized into(More)
