Percutaneous thermal ablation has proven to be an effective modality for treating both benign and malignant tumours in various tissues. Among these modalities, radiofrequency ablation (RFA) is the most promising and widely adopted approach that has been extensively studied in the past decades. Microwave ablation (MWA) is a newly emerging modality that is gaining rapid momentum due to its capability

Effects of acute exposure to ultra-wideband pulsed electromagnetic fields on the liver and kidneys of mice. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-12 Kaihong Guo,Yali Zhang,Xinlei Fang,Peiyao Fan,Sen Shang,Fan Fan,Hongyan Wu,Menghua Man,Yanzhao Xie,Xiaoyun Lu
The biosafety of ultra-wideband (UWB) pulses, which are characterized by simultaneously high power and a high bandwidth ratio, has gained increasing attention. Although there is substantial prior literature on the biological effects of UWB pulses on both cells and animals, an explicit, unequivocal and definite pattern of the corresponding biological responses remains elusive, and the systemic secondary

The Warburg hypothesis and weak ELF biointeractions. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-12 Abraham R Liboff
The Warburg observation concerning ATP generation in cancer cells is analyzed with regard to the likely involvement of H+ resonance effects on the angular velocity of the ATP synthase rotor. It is reasonable to expect that the variety of diseases associated with mitochondrial dysfunction may in part be related to the ATP synthase rate of rotation. Experimental measurements of ATP synthase rotational

The different sources of electromagnetic fields: Dangers are not limited to physical health. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-10 Fabien Deruelle
The impact of electromagnetic waves on health has been clearly established by many studies in recent decades. No State, with the exception of Russia, takes any real precautions in terms of standards for the population. Conflicts of interest and political lies are used to hide the truth about the dangers of electromagnetic pollution.In addition, it would seem that other sources of radiation than the

Specific low-frequency electromagnetic fields induce expression of active KDM6B associated with functional changes in U937 cells. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-10 Giulia Pinton,Angelo Ferraro,Massimo Balma,Laura Moro
In this study, we investigated the effects of specific low-frequency electromagnetic field sequences on U937 cells, an in vitro model of human monocyte/macrophage differentiation. U937 cells were exposed to electromagnetic stimulation by means of the SynthéXer system using two similar sequences, XR-BC31 and XR-BC31/F. Each sequence was a time series of 29 wave segments, equal to a total duration of

The inverse relation between mitochondrial transmembrane potential and proteins α-helix in neuronal-like cells under static magnetic field and the role of VDAC. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-09 Emanuele Calabrò,Salvatore Magazù,Monica Currò,Riccardo Ientile
In this study, a correlation between cell channel α-helices displacement and the mitochondrial transmembrane potential after exposure of 3, 7, 15 and 24 h of neuronal-like cells to a uniform magnetic field at the intensity of 2 mT was shown. Fourier Transform Infrared (FTIR) Spectroscopy and fluorescence techniques were used to analyze the secondary structure of protein content and mitochondrial transmembrane

Modulation of Maillard reaction and protein aggregation in bovine meat following exposure to microwave heating and possible impact on digestive processes: An FTIR spectroscopy study. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-06 Emanuele Calabrò,Salvatore Magazù
The aim of this study was to highlight the existence of a correlation between Maillard reaction and protein aggregation in bovine meat as a function of power level and exposure time used by microwave heating. The obtained results are compared with those of convective heating. For this, Fourier Transform-Infrared Spectroscopy was used to analyze the effects of microwave heating on different samples

Chromosome aberration in typical biological systems under exposure to low- and high-intensity magnetic fields. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-05 Emanuele Calabrò,Hit Kishore Goswami,Salvatore Magazù
The aim of this study was to investigate the response of chromosomes in typical human and plant cells under applied low-frequency magnetic fields at low and high intensities. Neuronal-like cells and roots of Allium sativum and Vicia faba were used to investigate chromosome's response to a static and 50 Hz magnetic fields at intensities ranging from 1 mT to 0.8 T, generated by two Helmholtz coils driven

Combination of low intensity electromagnetic field with chondrogenic agent induces chondrogenesis in mesenchymal stem cells with minimal hypertrophic side effects. Electromagn. Biol. Med. (IF 1.82) Pub Date : 2020-03-04 Roya Hesari,Mina Keshvarinia,Mahboubeh Kabiri,Iman Rad,Kazem Parivar,Hoorieh Hoseinpoor,Rezvan Tavakoli,Masoud Soleimani,Fatemeh Kouhkan,Soheila Zamanlui,Hana Hanaee-Ahvaz
Background: There are different methods to develop in vitro neo-chondral tissues from adipose-derived stem cells (ADSCs). Application of electromagnetic field (EMF) on ADSCs is one of popular approaches, which results in chondrogenesis. If chondrogenic impact of EMF on ADSCs is supposed to be generalized as a protocol in translational medicine field, possible emergence of early or late hypertrophic
