BACKGROUND AND PURPOSE Differences in hippocampal volume (HV) were compared between chronic primary insomniacs (PIs) and good sleepers (GSs), and the relationship between HV and memory function in PIs was investigated to clarify the effect of chronic sleep deprivation on brain structure and cognition. METHODS Twenty PIs (mean age, 50 years; 18 females)(More)
BACKGROUND AND PURPOSE The present study was designed to investigate whether 24 h of SD negatively affects the attention and working memory and increases the serum concentrations of stress hormones, glucose, and inflammatory markers. METHODS The acute effects of sleep deprivation (SD) on cognition and the stress hormones were evaluated in six healthy(More)
BACKGROUND AND PURPOSE The aim of this study was to determine the usefulness of three-dimensional (3D) scalp EEG source imaging (ESI) in partial epilepsy in comparison with the results of presurgical evaluation, magnetoencephalography (MEG), and electrocorticography (ECoG). METHODS The epilepsy syndrome of 27 partial epilepsy patients was determined by(More)
Transurethral resection of the prostate (TUR-P) is a common treatment for benign prostatic hyperplasia (BPH). However, the damage to the mucous membrane of the urethra leads to the complications. This paper reports a tubular organ resection manipulator for transurethral resection of the prostate which can minimize damage to the mucous membrane of the(More)
PURPOSE Antiepileptic drugs (AEDs) may have adverse effects on bone metabolism and bone mineral density (BMD). The aim of this study is to determine the changes of bone metabolism and BMD in epilepsy patients who are undergoing levetiracetam (LEV) monotherapy. METHODS Drug-naïve, sixty-one patients with recent onset epilepsy were recruited (24 female, 37(More)
AIMS To estimate the effect of levetiracetam (LEV) on cognitive function and mood status in newly diagnosed epilepsy patients. METHODS Fifty-five drug-naïve epilepsy patients (M:F ratio = 31:24; mean age = 30.9 years) were included. All patients underwent two neuropsychological (NP) tests, one before receiving LEV and then another 12.9 ± 5.0 months after(More)
Transurethral Resection of the Prostate (TUR-P) is the most common surgical procedure for Benign Prostatic Hyperplasia (BPH). However, damage to the mucous membrane of the urethra and extended surgery lead to complications. In order to resolve these problems, we propose a new prostatectomy, and develop a TUR-P manipulator, which has a prostate displacement(More)
