“…The optimal intensity is 3 mT SMF. These data are consistent with those which described by Sahebjamei et al [2007]. Similar to our results, the increased activity of superoxide dismutase and catalase activity was detected after long-term influence of magnetic field on suspension-cultured of tobacco cells.…”

“…Therefore, the impact of any stressors during seed germination can be displayed on the further development of the plant [Sahebjamei et al 2007]. Active forms of oxygen are always present in plant organism and can interact with different biological compounds to form free radicals.…”

“…The magnetic field with intensity of 150 and 200 mT and duration of exposure of one hour stimulates the formation of reactive oxygen in cells of soybean [Shine et al 2012]. Increased level of active forms of oxygen leads to the increase of antioxidant system activity which is the early response of the plants under the stress factor effect [Barаn 1998, Sahebjamei et al 2007, Shine et al 2011]. This mechanism is the basic of the plants adaptations to the external factors [Mamenko et al 2014].…”

Prooxidant-antioxidant system and change of alkaloids level in jimson weed (Datura stramonium L.) under the influence of static magnetic fieldWpływ stałego pola magnetycznego na układ prooksydacyjny i antyoksydacyjny oraz zmianę zawartości alkaloidów w bieluniu dziędzierzawie (Datura stramonium L.)Summary. The effect of magnetic radiation on the prooxidant-antioxidant system and alkaloids level in Jimson weed (Datura stramonium L.) have never been studied and reported before. The objective of this research was to study the influence of static magnetic field on the homeostasis and alkaloids level in D. stramonium. The level of (thio) barbituric acids active products, superoxide dismutase and catalase activity in D. stramonium seedlings under the influence of static magnetic field with the intensity of 3 mT and 10 mT at two exposure times, 30 min and 22 hours, was studied. Under these conditions, the level of alkaloids in the extract from leaves and stems of germs was determined by chromatographic analysis. An increased level of lipid peroxidation products, the activity of superoxide dismutase and catalase in seedlings under the long-term effect of magnetic field were observed. The level of scopolamine alkaloid depended on the duration of exposure to the static magnetic field; however, this factor did not effect the atropine level. The obtained experimental data was confirmed by the results of the analysis of variance.

“…MACS use involves the passage of sperm through a high power static magnetic field (SMF) of 0.5 T and up to 1.5 T [82,83]. Several researches have shown that SMF can generate some kind of effect on biological systems, as pro-inflammatory changes and increase in the generation of ROS [84][85][86], which is highly detrimental to sperm. Although the mechanism by which SMF affects cells is not well understood, some reports speculate that it might increase the activity, concentration, and life time of paramagnetic free radicals, which could ultimately produce oxidative stress, genetic mutations, and/or apoptosis [87][88][89].…”

Innovative methods to select sperm subpopulations with the best fertilizing ability are needed in assisted reproductive techniques (ART) in order to improve fertilization and pregnancy rates, while also considering possible epigenetic effects on the offspring. Molecular based selection methods are searched for, under the premise that they could be an improvement over classical selection by morphology and movement. One of these methods sustains the elimination of sperm that can bind to annexin A5 (ANX V), coupled to paramagnetic beads, through the phosphatidyl-serine exposed on their membranes upon apoptosis. Although reports accumulate about the use of this method, controversy persists as to the benefits of ANX V based sperm selection in ART. In this review we consider the arguments in favour and against this method and conclude that to the moment the evidence does not support MACS regular use in ART.

Little is known about the influence of magnetic fields (MF) on growth of microalgae such as Chlorella vulgaris, which has been consumed as health food for various nutritional and pharmacological effects. This preliminary study investigated whether static MF can modulate the antioxidant system in C. vulgaris by exposing the cells to static MF generated by dual yoke electromagnets with magnetic flux density of 10-50 mT for 12 h. After exposure to 10-35 mT for 12 h, the activity of superoxide dismutases and peroxidase increased significantly compared to control cells. However, a remarkable increase of catalase activity occurred at 45 and 50 mT. The lipid peroxidation of algae cells determined by production of thiobarbituric acid-reactive substances was much increased when exposed to 35, 45, and 50 mT of MF. The scavenging ability of 2,2-diphenyl-1-picrylhydrazyl radical was decreased markedly while there was no variation of total carotenoids content in C. vulgaris cells. Assay of specific growth rate in 72 h cultivation after MF exposure was also conducted. In groups after exposure to 10-35 mT of MF, specific growth rate was significantly increased. These results suggest that 10-35 mT of static MF exposure could promote the growth of C. vulgaris and regulate its antioxidant defense system to protect cells efficiently, which could possibly enhance the growth of C. vulgaris in industrialized cultivation by MF.
