Objective(s):Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. Materials and Methods: Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were ...

Much effort has been made to understand the organizational principles of human brain function using functional magnetic resonance imaging (fMRI) methods, among which resting-state fMRI (rfMRI) is an increasingly recognized technique for measuring the intrinsic dynamics of the human brain. Functional connectivity (FC) with rfMRI is the most widely used method to describe remote or long-distance ...

The potential of solid-state NMR (SSNMR) spectroscopy as a tool for investigating complicated biological problems has long been appreciated. The spectroscopic selectivity possible with biosolids NMR is unique in answering mechanistic questions, allowing one to measure in situ the structure and dynamics of specific sites in insoluble biomolecular complexes at atomic resolution. It has also shown...

Introduction: Simultaneous Multi-Slice (SMS) imaging [1] using MultiBand (MB) RF pulses has shown great success in functional and diffusion weighted (DW) MRI studies of the brain [2-5]. Recently, this technique has been combined with parallel transmission (pTx) and it has been demonstrated that pTx MB pulse design [6] can significantly improve transmit B1 (B1+) homogeneity at 7T and/or reduce R...

We present an analysis of a devised sample of Rotation Curves (RCs), aimed at checking the consequences of a modified f(R) gravity in galactic scales. Originally motivated by the the dark energy mystery, this theory may serve as a possibility of explaining the observed non-Keplerian profiles of galactic RCs in terms of a breakdown of the Einstein General Relativity. We show that in general the ...

Several techniques have been proposed for estimating and compensating for the effects of quadrature modulators and demodulators. Several of them will be discussed in this survey including those that observe the envelope of signals, the pilot tones of OFDM signals, and others.

background: induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. an incoherent noise field is supposed to suppress the bioeffects of regular rf electromagnetic fields. the purpose of this study was to investigate the effect of gsm mobile phone-induced radiofrequency (rf) on the induction of oxidative stress in sp2/0 cell line. materials and meth...

The ground state hyperfine transition frequency of hydrogen is known to a very high precision and therefore the measurement of this transition frequency in antihydrogen is offering one of the most accurate tests of CPT symmetry. The ASACUSA collaboration at CERN will run an experiment designed to produce ground state antihydrogen atoms in a cusp trap. These antihydrogen atoms will pass with a l...
