CONTROL OF STAPHYLOCOCCUS AUREUS ACTIVITY IN RATS USING ELECTROMAGNETIC SIGNALS AT RESONANCE FREQUENCY "IN VIVO STUDY

In this work, the frequency of electric impulses that interfere withthe bioelectric signals generated during staphylococcus aureus (S.aureus)cellular division is investigated. The experiment was expanded to in vivostudy for the obtained data in which rats were infected with S.aureus andthen whole body exposure were exposed to square electric pulses (SEP) thatcauses inhibition to the microbial cellular growth. Another group of animalswas infected by previously inhibited bacteria with SEP then the histologicaland molecular structures of the liver were investigated for all the animalgroups, Dielectric relaxation studies for the liver in the frequency range 42KHz-5MHz was used to determined molecular structure changes.The results indicated a highly significant inhibition of cellular growth forS.aureus in addition to pronounced changes in the cellular morphology afterthe exposure of the micro-organism to the resonance frequency of 0.8 HzSEP for 120 minutes. From the histological and dielectric relaxationmeasurements and results it was indicated that the liver for animals infectedby S.aureus and then exposed to SEP showed significant improvement intheir health state as compared with infected and non exposed group.Moreover, the liver for the animals infected with previously treated bacteriawith SEP showed highly significant decrease in cellular damage as compared with untreated bacteria. It was concluded that treatment ofS.aureus by 0.8 Hz SEP acts on the structure and biological activity ofthe bacteria and it is a promising methodology to control S.aureus activity invivo and in vitro applications

Effects of extremely low frequency electromagnetic fields on kidney functions of albino rats in vivo study

Abstract In the present study fifty male albino rats were equally divided into three groups namely A, B and C, group A used as control group, groups B and C were divided into two subgroups namely B 1 , B 2 and C 1 , C 2 respectively. B 1 & C 1 were exposed to 50Hz, 3KV/m electric field (EF) for the periods of 15, 30 days respectively; B 2 &C 2 were housed at normal environmental conditions for the periods of 15, 30 days respectively. Fresh samples of kidney and blood were collected for experimental investigations. The dielectric constant (έ) and electrical conductivity (σ) were measured to investigate any changes in kidney structure. Kidney function was studied through analysis of urea & creatinine after exposure to EF. The results show high significant changes in the value of έ and σ of kidney for all groups as compared with control. EF can induce significant increase in the levels of kidney profile creatinine & urea, these variations were recovered during two weeks after stopping exposure but they did not return to its original control values. Kidney histological section showed abnormal configuration of renal tubules, congested blood vessel and degenerated renal tubules, necrosis, glomerular shrinkage, and increase in space between glomerulus and Bowman's capsule

Ternary Ti-Mo-Fe Nanotubes as Efficient Photoanodes for Solar-Assisted Water Splitting

Designing efficient and stable water splitting photocatalysts is an intriguing challenge for energy conversion systems. We report on the optimal fabrication of perfectly aligned nanotubes on trimetallic Ti-Mo-Fe alloy with different compositions prepared via the combination of metallurgical control and facile electrochemical anodization in organic media. The X-ray diffraction (XRD) patterns revealed the presence of composite oxides of anatase TiO2and magnetite Fe3O4with better stability and crystallinity. With the optimal alloy composition Ti-(5.0 atom %) Mo-(5.0 atom %) Fe anodized for 16 h, enhanced conductivity, improved photocatalytic performance, and remarkable stability were achieved in comparison with Ti-(3.0 atom %) Mo-(1.0 atom %) Fe samples. Such optimized nanotube films attained an enhanced photocatalytic activity of ∼0.272 mA/cm2at 0.9 VSCE, which is approximately 4 times compared to the bare TiO2nanotubes fabricated under the same conditions (∼0.041 mA/cm2at 0.9 VSCE). That was mainly correlated with the emergence of Mo and Fe impurities within the lattice, providing excess charge carriers. Meanwhile, the nanotubes showed outstanding stability with a longer electron lifetime. Moreover, carrier density variations, lower charge transfer resistance, and charge carriers dynamics features were demonstrated via the Mott-Schottky and electrochemical impedance analyses
