In this paper a CPW-fed annular slot antenna is miniaturized with enhanced impedance bandwidth using a reactive impedance surface (RIS) substrate. The RIS is realized by patterning 3× 3 array of circular elements over an inexpensive FR-4 substrate which is backed by a circular metallic plane. Due to the compensation of electric and magnetic energy stored by antenna and RIS substrate respectivel...
BACKGROUND The aim of the present study was to assess the prevalence of insomnia in chronic tinnitus and the association of tinnitus distress and sleep disturbance. METHODS We retrospectively analysed data of 182 patients with chronic tinnitus who completed the Tinnitus Questionnaire (TQ) and the Regensburg Insomnia Scale (RIS). Descriptive comparisons with the validation sample of the RIS in...
Background and Objectives: To compare the safety and efficacy of haloperidol and risperidone in the treatment of delirium and its subtypes Methods: We collected sociodemographic data and medical variables in addition to systematically rating all patients with delirium with the Memorial Delirium Assessment Scale (MDAS), Karnofsky Performance Status Scale (KPS) and abbreviated Udvalg for Kliniske...
BACKGROUND/AIMS The aim of this study was to investigate the effects of an atypical antipsychotic risperidone (RIS; 0.06, 0.125 or 0.25 mg/kg, intraperitoneal, i.p.) on learning and memory processes, both in naive and MK-801-treated (0.15 mg/kg, i.p.) rats. METHODS Modified elevated plus maze (mEPM), passive avoidance (PA) and Morris water maze (MWM) tasks were used. RESULTS In the mEPM tes...
INTRODUCTION The aim of this study was to define the reference intervals (RIs) in a Turkish population living in Northeast Turkey (Erzurum) for 34 analytes using direct and indirect methods. In the present study, the regional RIs obtained were compared with other RI studies, primarily the nationwide study performed in Turkey. MATERIALS AND METHODS For the direct method, 435 blood samples were...
UNLABELLED The aim of this study was to evaluate the role of radioimmunoscintigraphy (RIS) directed against prostate-specific membrane antigen (PSMA) in influencing postradical retropubic prostatectomy (RRP) radiotherapy (RT) decision making. METHODS The records of consecutive patients who underwent RRP, who were referred for consideration of RT, and for whom an RIS scan was obtained were rev...
A simple and sensitive method for the spectrophotometric determination of risperidone (RIS) is proposed. The method is based on the oxidation of the drug using chloramine-T (CAT) and the excess oxidant is determined by either xylene cyanol FF (XCFF) or malachite green (MG), the absorbances of which are measured at 612 or 619 nm for RIS-XCFF and RIS-MG respectively. Under the proposed optimum co...
BACKGROUND Several clinical reports have documented a beneficial effect of the addition of a low dose of risperidone to the ongoing treatment with antidepressants, in particular selective serotonin reuptake inhibitors, in the treatment of drug resistant depression. The aim of our study was to understand the mechanism of the clinical efficacy of a combination of fluoxetine (FLU) and risperidone ...
BACKGROUND: Radiation therapy (XRT) is an important modality in the treatment of cancer, and XRT is now commonly utilized in the treatment of early-stage breast cancer. However, its use has occasionally resulted in the development of secondary malignancies. We present a critical review of radiation-induced sarcoma (RIS) that develops after irradiation for the treatment of breast cancer. METHODS...
Hypertension with high homocysteine (HHcy) (H-type hypertension) and C reactive protein (CRP) can increase the incidence of ischemic stroke. However, it is not clear whether recurrent ischemic stroke (RIS) is related to H-type hypertension and CRP. The present study investigated the correlation of H-type hypertension and CRP level with RIS. Totally, 987 consecutive patients with acute ischemic ...
