The present study provides an observation and documentation on the effect of static magnetic field on the growth of Triticum aestivum. The seeds are allowed to germinate and the seedlings are grown in an environment of the controlled static magnetic field while other physical factors such as temperature, light exposure, soil pH, etc. are held constant. Also, a comparison of influence on the average height between both the poles of the magnet is estimated and north pole oriented magnet is found to imply a significant difference. Finally some of the potential applications of the study in non-invasive protein silencing, GMO production, Vertical farming and Terraforming are briefly discussed.

The aim of the present study was to compare the EEG signal recorded outside and inside a 1.5T magnetic resonance (MR) scanner. The EEG was recorded in eyes open and eyes closed conditions using a digital recording MR-compatible system. To characterize how a static magnetic field induces changes in EEG signal, EEG data were analyzed using FFT frequency analysis. No significant difference between the alpha powers recorded outside and inside the magnetic field was observed in eyes closed conditions. However, in eyes open condition there was a significant increase in alpha power inside the magnet in comparison to the outside position. The changes in alpha power according to the eyes open/closed conditions could be inversely correlated to a subject's state of wakefulness and due to some physiological changes, rather than an effect of the magnetic field. This experiment suggests that subjects' state of wakefulness is of prime concern when performing functional MRI.

The effect of static magnetic field (MF) on the growth and biochemical indices of five fungal genera were studied. Exposing the above genera to the northern pole, southern pole and both poles and their influences were compared with the control treatment (without MF energy). The static MF of 10 gauss was applied to the above fungal genera for seven days at 28°C. The effect of static MF energy on the growth of fungal genera on solid media Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA) was classified as stimulatory, inhibitory and no observable effect on growth of fungal genera. The effects of MF poles (southern, northern and both) inhibited the growth of Fusarium oxysporum, while the MF poles stimulated the growth of fungal genera (Aspergillus niger, Alternaria alternate and Penicillium chrysogenium) and had no observable effect of southern pole and both poles on growth of Rhizopus oryzae, while the northern pole inhibited the growth of R. oryzae compared with control group by measuring the growth diameter (cm). The effects of MF poles on the biochemical indices of the fungal genera were performed by filtering the growth and measuring the enzyme activity in the filterate. Exposing the fungal genera to the northern pole, southern pole. The fungal genera were influenced by MF energy for 3 days at 28°C and pH6.5 showed increased in the activities of amylase and protease due to northern pole at significant difference (at the 0.05 levels), the northern pole increased amylase activity (U/ml) in the culture medium filteratedof P. chrysogenumup to (0.246 U/ml) higher than other mentioned genera, A. niger, F. oxysporum, R. oryzae and A. alternata 0.172, 0.146, 0.116, 0.105U/ml respectively. The northern pole increased protease activity (U/ml) in the culture filterate of P. chrysogenumup to (0.081 U/ml) higher than other mentioned genera, A. niger, A. alternata , R. oryzae and F. oxysporum 0.08, 0.074, 0.056,0.054U/ml respectively and decreased when treated with southern pole however it was higher than the control treatment under optimum condition.

AbstractStatic magnetic field (SMF) is reported to mimic chelation agents. In thalassemia blood, SMF minimizes iron overloading effect. In such cells ROS level is reduced, in presence of moderate strength (70mT). Pilot study on transfusion dependent thalassemia, thalassemia carriers and normal red blood clearly indicate the differential effects of SMF on thalassemia, thalassemia carrier and normal cells. SMF also reduces ROS induced DNA damage in lymphocytes. A comparative study on the iron chelating drug deferasirox and SMF treated lymphocytes further confirm our main thesis. This non-invasive therapeutic regime for hemochromatosis may serve the dual purpose of treating, iron overloading and minimizing, cellular damage by lowering the ROS level.

Sodium fluoride solution was injected i.p. to three groups of rats at a dose equivalent to 0.1 LD50 three times a week up to 18 injections. Two out of these groups and two out of three groups were sham-injected with normal saline and were exposed to the whole body impact of a 25 mT static magnetic field (SMF) for 2 or 4 hr a day, 5 times a week. Following the exposure, various functional and biochemical indices were evaluated along with histological examination and morphometric measurements of the femur in the differently exposed and control rats. The mathematical analysis of the combined effects of the SMF and fluoride based on the a response surface model demonstrated that, in full correspondence with what we had previously found for the combined toxicity of different chemicals, the combined adverse action of a chemical plus a physical agent was characterized by a tipological diversity depending not only on particular effects these types were assessed for but on the dose and effect levels as well. From this point of view, the indices for which at least one statistically significant effect was observed could be classified as identifying (I) mainly single-factor action; (II) additive unidirectional action; (III) synergism (superadditive unidirectional action); (IV) antagonism, including both subadditive unidirectional action and all variants of contradirectional action.
