Background: The electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful.Objective: Removing electrocardiogram contamination from electromyogram signals.Methods: In this paper, the clean electromyogram signal, electrocardiogram artifact and e...

We present a vision and preliminary results for a combined RF-Biological Systems where the Electro-Magnetic energy of RF signals is transduced into control-signals for biological signaling-processes. We show how such systems can be used to build extremely low-power sensor networks. We present our approach and propose a system architecture constituted of a passive RF Front End (RF-FE), Bio-Mecha...

in  this  study  we  determined  the  frequency,  sensitivity  and  specificity  of  anti  cyclic citrullinated peptides (anti-ccp) igg antibody, total rheumatoid factor (rf-t), and rf isotypes in iranian patients with rheumatoid arthritis (ra) and their association with age, clinical and serological parameters. anti-ccp and rf-t and rf isotypes level were measured in 418 patients and 399 healt...

INTRODUCTION: Serine (Ser), a co-agonist at N-methyl-D-aspartate receptors, has three coupled spins resonating at 3.98, 3.94 and 3.83 ppm [1]. Because of its low concentration (~0.5 mM) and the overlap with primarily the creatine (Cr) 3.92 ppm singlet, detection of Ser in human brain by H-MRS remains as a challenge. A spectrally-selective refocusing approach, that is the first attempt to measur...

This article is related to the experimental data regarding the ability of MRET Noise Field Generator (MRET NFG) placed at the distance of 7 feet from “phantom head” exposed to RF phones radiation to reduce specific absorption rate (SAR) of the water based solution inside “phantom head”. The core part of Generator is MRET polymer compound. Due to the fractal geometry structure of MRET polymer co...

Single-shot STEAM MRI [1] is insensitive to off-resonance effects because it is based on RF refocused echoes but suffers from a inherently low signal-to-noise ratio (SNR). Recently, gradient and stimulated echo (GRASTE) imaging [2] has been shown to ameliorate the limitations of single-shot STEAM by improving the SNR efficiency. Here, an extension of 2D GRASTE is presented that is capable of ac...
