Magnetic Fe3O4 nanoparticles (MNPs) have shown promise as drug carriers for treating lung and liver tumors in vivo. However, little is known about the combined delivery of these MNPs with a second approach, extremely low frequency electro-magnetic field (ELFF) exposure, which has been shown to have value for in vitro treatment of tumor cells. Here, ELFF and MNPs were combined to treat healthy (HL-7702) and cancerous (Bel-7402, HepG2) hepatic cells lines to explore the potential therapeutic effects, bio-mechanisms, and potential toxicity of a combined drug-free treatment in vitro...

Ferro-Magnetic nanoparticles (Fe-MNP) have gained a lot of attention in biomedical and industrial applications due to their biocompatibility, ease of surface modification and paramagnetic properties. The basic idea of our study is whether it is possible to use glucose-conjugate Fe-MNP (Glc-Fe-MNP) for targeting and more accurate focusing in order to increase the effect of high-frequency electromagnetic fields induced hyperthermia in solid tumors. Tumors demonstrate high metabolic activity for glucose in comparison with other somatic cells...

BACKGROUND: The use of near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) for sentinel lymph node (SN) mapping has been investigated in lung cancer; however, this has not been fully adapted for minimally invasive surgery (MIS). The aim of our study was to develop a minimally invasive SN mapping integrating pre-operative electro-magnetic navigational bronchoscopy (ENB)-guided transbronchial ICG injection and intraoperative NIR thoracoscopic imaging. METHODS: A NIR thoracoscope was used to visualize ICG fluorescence...

In the present developed world, all of us are flooded with electromagnetic radiations (EMR) emanating from generation and transmission of electricity, domestic appliances and industrial equipments, to telecommunications and broadcasting. We have been exposed to EMR for last many decades; however their recent steady increase from artificial sources has been reported as millions of antennas and satellites irradiate the global population round the clock, year round. Needless to say, these are so integral to modern life that interaction with them on a daily basis is seemingly inevitable; hence, the EMR exposure load has increased to a point where their health effects are becoming a major concern...

Extremely low frequency electro magnetic fields (EMFs) have been classified as possibly carcinogenic to humans by the International Agency for Research on Cancer. An increased number of chromosomal alterations in peripheral lymphocytes are correlated with elevated incidence of cancer. The aim of the present study was to assess occupationally induced chromosomal damage in EMF workers exposed to low levels of radiation. We used conventional metaphase chromosome aberration (CA) analysis and the micronucleus (MN) assay as biological indicators of non ionizing radiation exposure...

In a previous research, we have described and documented self-assembly of geometric triangular chiral hexagon crystal-like complex organizations (GTCHC) in human pathological tissues. This article documents and gathers insights into the magnetic field in cancer tissues and also how it generates an invariant functional geometric attractor constituted for collider partners in their entangled environment. The need to identify this hierarquic attractor was born out of the concern to understand how the vascular net of these complexes are organized, and to determine if the spiral vascular subpatterns observed adjacent to GTCHC complexes and their assembly are interrelational...

The ultimate goal of this study is to develop a tumor-specific multi-functional, nano-entity that can be used for both cancer detection and treatment. Low heat (42 approximately 45 degrees C) hyperthermia is an effective cancer treatment method with little side effect. Magnetic nanoparticles, such as Fe3O4, can be heated by alternating electromagnetic (AEM) fields at well selected frequencies, without heating normal tissue. Nanogold particles (NGPs) are effective optical absorbers and also excellent fluorescent enhancers...

BACKGROUND: Numerous studies have implied that paternal occupational exposures, in particular electromagnetic fields (EMF) and ionizing radiation, may be involved in the etiology of childhood cancers. We investigated whether an association exists between paternal occupations at birth involving such exposures and cancer risk in offspring, using data from the Northern Region Young Persons' Malignant Disease Registry (NRYPMDR). PROCEDURE: Cases (n=4,723) were matched, on sex and year of birth, to controls from two independent sources: (i) all other patients from the NRYPMDR with a different cancer, (ii) 100 cancer-free individuals per case from the Cumbrian Births Database...

An increased risk of mesothelioma has been reported among individuals experiencing residential exposure to asbestos, while results for lung cancer are less consistent. Several studies have reported an increased risk of lung cancer risk from outdoor air pollution: on the basis of the results of the largest study, the proportion of lung cancers attributable to urban air pollution in Europe can be as high as 10.7%. A causal association has been established between second-hand tobacco smoking and lung cancer, which may be responsible for 1...

Extremely low frequency (ELF) electromagnetic field (EMF) is thought to prolong the life of free radicals and can act as a promoter or co-promoter of cancer. 8-hydroxy-2'-deoxyguanosine (8OHdG) is one of the predominant forms of radical-induced lesions to DNA and is a potential tool to asses the cancer risk. We examined the effects of extremely low frequency electro magnetic field (ELF-EMF) (50 Hz, 0.97 mT) on 8OHdG levels in DNA and thiobarbituric acid reactive substances (TBARS) in plasma. To examine the possible time-dependent changes resulting from magnetic field, 8OHdG and TBARS were quantitated at 50 and 100 days...

Hyperthermia, the procedure of raising the temperature of tumour-loaded tissue to 40-43 degrees C, is applied as an adjunctive therapy with various established cancer treatments such as radiotherapy and chemotherapy. The potential to control power distributions in vivo has been significantly improved lately by the development of planning systems and other modelling tools. This increased understanding has led to the design of multiantenna applicators (including their transforming networks) and implementation of systems for monitoring of E-fields (eg, electro-optical sensors) and temperature (particularly, on-line magnetic resonance tomography)...

BACKGROUND: There are only a few epidemiologic studies investigating risk factors in persons occupationally exposed to high-frequency radiation (e.g. radio-, TV-waves, mobile phones or microwaves). The results of the studies are mostly inconsistent. METHODS: All epidemiologic studies which investigated the association between occupational exposure to high-frequency radiation and the risk of leukemia, brain tumors or breast cancer were included in this review. All studies published between 1980 and 1997, such as record-linkage, case-control, and cohort studies, were retrieved from MEDLINE...

The literature indicates that exposure to electro-magnetic fields (EMF) may result in an increased incidence of cancer and spontaneous abortion. The aim of the present study was to determine whether living closer to high voltage power lines (HVPL) increased the risk of congenital anomalies. We studied residential exposure in any municipality in the Central-East Region of France where there was at least one residence within 500 metres of a HVPL. This was a matched case-control design. The cases consisted of all children with congenital anomalies, identified to the population-based registry in Central-East France between 1988-91...

Several studies have raised the possibility that exposure to electrical and/or magnetic fields may be injurious to health in particular by the promotion or initiation of cancer. To investigate whether the electricity transmission system presents a long term hazard to public health, the mortality of nearly 8,000 persons, identified as living in the vicinity of electrical transmission facilities at the time of the 1971 Population Census, has been followed to the end of 1983. All identified transmission installations within pre-defined areas were included in the study with the result that the greater part of the study group were believed to be resident near relatively low voltage sub-stations...

Using the "Bi-Digital O-Ring Test Molecular Identification and Localization Method," one can identify and localize minute amounts of bioactive substances (including neurotransmitters), micro-organisms, toxic substances, or drugs, and, in addition, one can non-invasively image normal organs as well as screen for and image the distribution of specific types of cancer of specific internal organs without using any expensive instrumentation. One can also use this method to perform a qualitative analysis of neurotransmitters, neuromodulators, and hormones on different parts of the imaged organs...

The fundamental intrinsic electro-gravitational (neutrino-photon-phonon transduction) mechanism of human life is proposed. The essential physico-mathematical model for chemical electromagnetic photon-phonon conversions in human systems is presented, the underpinning of which is Jacobson resonance which is represented by mc2 = Bvl coulomb. This equation sets in dual resonance gravitational potential and electromagnetic potential. Basic EM interactions occurring in human systems produce gravity waves through elastic deformation of the gravitational field, thus promulgating a monopolar wave which results in a quantized vibration of the crystalline lattices of particulate masses...

Unsuspected prolonged exposure to abnormal environmental (very high frequency) electro-magnetic fields (EMF), electric fields (EF) or magnetic fields (MF) at 60 Hz or 16K Hz in the bedroom or workplace may contribute to the development of various intractable medical problems. Most of the clinical symptoms appear when the individuals are exposed to EMF for many hours a day for at least several months to 1-year for relatively benign diseases or symptoms (such as intractable pain or medical problems), or several to over 10 years for more serious diseases (such as cancers of the digestive system or other organs), all of which seem to appear with the additional co-existence of micro-circulatory disturbances with Thromboxane B2 (TXB2), bacterial or viral infections and decrease or absence of acetylcholine, and lead, mercury, or aluminum deposits, with or without asbestos...
