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 ...

Commercial rhododendron plants have been the most important hosts of Phytophthora ramorum in Europe. As part of the European Union (EU) emergency phytosanitary measures 2002/757/EU and 2004/426/EU all commercial rhododendron-growing premises are surveyed for P. ramorum. Detection of P. ramorum leads to quarantine measures, including destruction of plants, and could lead to considerable financia...

dietary flavonoids show beneficial effects in the prevention of chronic diseases. however, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. in the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (bsa) were investigated by fluorescence spectroscopy. the binding affinities of t...

The essential oil of Rhododendron anthopogon was investigated by GC-MS, and seventeen compounds (representing approximately 98% of the oil) were identified. The major components of the aerial parts of the oil were the monoterpenes alpha-pinene, beta-pinene, limonene and the sesquiterpene delta-cadinene. Biological studies revealed a weak topical anti-inflammatory activity; a significant killing...

The purpose of this study to investigate phytochemical screening and TLC fingerprinting selected medicinal plant used for antilithiatic activity. Phytochemical tests were performed on extracts determine the presence several chemical elements such as Glycoside, Terpenoid, Flavonoids, Tannins, other compounds that are responsible biological activity extract. To end, ethanolic Nyctanthes arbor-tri...

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.
