Objective(s): Nowadays, the electromagnetic field-emitting devices are used routinely in our lives. Controversial reports exist concerning the effects of mobile radiofrequency (RF) on different parts of the body, especially stress hormones. The main goal of the present work was to study the long-term effects of mobile RF900 MHz exposure with special focus on the adrenal gland pathophysiology an...

PURPOSE This research assessed the influence of visual speech on phonological processing by children with hearing loss (HL). METHOD Children with HL and children with normal hearing (NH) named pictures while attempting to ignore auditory or audiovisual speech distractors whose onsets relative to the pictures were either congruent, conflicting in place of articulation, or conflicting in voicin...

Objectives. To assess the reliability of the automated radio frequency (RF)-based US measurement of carotid intima media thickness (IMT) performed by rheumatologists and to evaluate the variability between this method and the conventional B-mode US measurement of carotid IMT in RA patients. Methods. Twelve rheumatologists measured in two blinded rounds the IMT of both common carotid arteries (C...

Radio-Frequency (RF) ablation is a minimally invasive method for treatment of primary and metastatic hepatic tumors. A catheter is introduced transcutaneously into the tumor, and tissue is heated up by application of radio-frequency current. In this work, I present the application of the Finite Element Method (FEM) for creating models of hepatic RF ablation to evaluate and improve catheter desi...

BACKGROUND AND AIM: In public health, health literacy (HL) is rather a new conception. In this regard, oral health as a critical public health issue that affects women’s health. The objective of the present study was to determine oral health self-care behavior and its relationship with HL.METHODS: This cross-sectional study was performed on 232 women who referred to health centers of Tabriz, Ir...

Introduction: A conformal RF coil array design for use in a MRI system is proposed. In particular, the coil array is designed without the use of any cumbersome mutual decoupling schemes. Coil elements are designed based on orthogonality, which will naturally minimise the problematic mutual coupling effects that inherently exist in most MRI phased-array systems [1]. A prototype of a knee coil co...

Hodgkin lymphoma (HL) accounts for about 10% of all childhood cancers. Five-year survival rates with modern therapies are now approaching >90-95% as a consequence of its significant sensitivity to both chemotherapy and radiation. The current challenge is to determine how much therapy is needed to improve survival and how to adapt treatment to the patient to prevent these long term toxicities. T...

introduction: children learn to communicate by hearing sounds. if there is hearing loss, the cognitive and speaking abilities and language learning will deteriorate. early detection and intervention are important factors in the successful treatment of hearing loss in children. hearing loss (hl) is divided into two main groups: conductive hearing loss (chl) and sensorineural hearing loss (snhl),...

Article history: Received 28 April 2011 Received in revised form 10 July 2012 Accepted 14 July 2012 Available online 11 September 2012 In this paper, we propose the Hybrid-Layer Index (simply, the HL-index) that is designed to answer top-k queries efficiently when the queries are expressed on any arbitrary subset of attributes in the database. Compared to existing approaches, the HL-index signi...
