Non-thermal microwave/lower frequency electromagnetic fields (EMFs) act via voltage-gated calcium channel (VGCC) activation. Calcium channel blockers block EMF effects and several types of additional evidence confirm this mechanism. Low intensity microwave EMFs have been proposed to produce neuropsychiatric effects, sometimes called microwave syndrome, and the focus of this review is whether th...
Riverside: Animal cancer studies using a mouse skin model on co-promotion by 60 Hz EMFs with the initiator dimethylbenzanthracene and the promoter 12O-tetradecanoylphorbol13acetate; * Charles Graham, Midwest Research Institute, Kansas City, Missouri: Human studies on the effects of nighttime EMF exposures on melatonin, other hormones, and the immune system; * Sek Wen Hui, Roswell Park Cancer In...
The aim of the present study was to investigate on the effects of a low-frequency pulsed electromagnetic field (LF-PEMF) in an experimental cell model of Alzheimer's disease (AD) to assess new therapies that counteract neurodegeneration. In recent scientific literature, it is documented that the deep brain stimulation via electromagnetic fields (EMFs) modulates the neurophysiological activity o...
Long-term exposure to extremely-low-frequency electromagnetic fields (ELF EMFs) greater than 0.4 microT has been linked, by epidemiological studies, to a small elevated risk of childhood leukaemia. Laboratory-based experiments have been claimed to show that ELF EMFs induce a variety of biological responses, although these claims are controversial. Recent experiments by Ivancsits et al. [Mutat. ...
The objective of the present study was to investigate changes in spontaneous EEG activity during cortical spreading depression (CSD) in mice brain. The cortical region of anaesthetized mice were exposed to the electromagnetic fields (EMFs) emitted from a mobile phone (MP, 935.2-960.2 MHz, 41.8 mW/cm(2)). The effect of EMFs on EEG was investigated before and after exposure to different stimuli (...
Since the first proposal that fullerenes are capable of hosting atoms, ions, or clusters by the late Smalley in 1985, tremendous examples of endohedral metallofullerenes (EMFs) have been reported. Breaking the dogma that monometallofullerenes (mono-EMFs) always exist in the form of M@C2n while clusterfullerenes always require multiple (two to four) metal cations to stabilize a cluster that is u...
We provide an analysis of the nature of emfs induced during the operation of a railgun. The focus here is on the railguns, but the results are applicable to a broad range of similar distributed parameter problems. The main sources of induced emfs are current changes and armature motion. New perspectives are presented. It is shown, for example, that there is no true motional emf in railguns, and...
The growing use of wireless communication devices has been significantly increasing the level high frequency electromagnetic fields (EMFs) in environment, which raises a concern for possible deleterious effects on living organisms. Long lasting exposure to low-intensity EMFs can cause molecular and cellular level, number morphological physiological changes. aim this work was investigate 2.41 GH...
Background: Blunt injuries to the gallbladder occur rarely, and the incidence of isolated damage to the gallbladder is even smaller. We report a case of delayed presentation of isolated rupture of the gallbladder following blunt trauma to the abdomen. Case presentation: A 65 year old lady presented through the Emergency Department with a 1 week history of blunt trauma to her abdomen. She compla...
