Effects of Moderate to High Static Magnetic Fields on Reproduction Bioelectromagnetics (IF 1.9) Pub Date : 2022-04-29 Chao Song, Biao Yu, Junjun Wang, Yiming Zhu, Xin Zhang
With the wide application of magnetic resonance imaging in hospitals and permanent magnets in household items, people have increased exposure to various types of static magnetic fields (SMFs) with moderate and high intensities, which has caused a considerable amount of public concern. Studies have shown that some aspects of gametogenesis and early embryonic development can be significantly affected

LF-EMF Compound Block Type Signal Activates Human Neutrophilic Granulocytes In Vivo Bioelectromagnetics (IF 1.9) Pub Date : 2022-04-28 Jan J. M. Cuppen, Cristian Gradinaru, Bregje E. Raap - van Sleuwen, Anna C. E. de Wit, Ton A. A. J. van der Vegt, Huub F. J. Savelkoul
This research aims to demonstrate in a randomized, placebo-controlled crossover design study that a nominal 5 μT low-frequency electromagnetic field (LF-EMF) signal for 30 min activates neutrophils in vivo in humans. Granularity of neutrophils was measured in blood samples of healthy human volunteers (n = 32) taken before and after exposure for both the exposure and control sessions. A significant

An International Collaborative Animal Study of the Carcinogenicity of Mobile Phone Radiofrequency Radiation: Considerations for Preparation of a Global Project Bioelectromagnetics (IF 1.9) Pub Date : 2022-04-27 Young Hwan Ahn, Katsumi Imaida, Yong-Bum Kim, Kang-Hyun Han, Jeong-Ki Pack, Nam Kim, Sang Bong Jeon, Ae-Kyoung Lee, Hyung Do Choi, Jianqing Wang, Mayumi Kawabe, Hye Sun Kim
Radiofrequency radiation (RFR) was classified as a “possible” human carcinogen in 2011, which caused great public concern. A carcinogenicity study by the National Toxicology Program (NTP) found Code Division Multiple Access—and Global System for Mobile Communications—modulated mobile phone RFR to be carcinogenic to the brain and heart of male rats. As part of an investigation of mobile phone carcinogenesis

Evaluation of Atopic Dermatitis Improvement Caused by Low-Level, Low-Frequency Pulsed Electromagnetic Fields Bioelectromagnetics (IF 1.9) Pub Date : 2022-04-27 Jun-Young Kim, Ji-Young Lee, Ja-Woo Lee, Soo-Kyung Lee, Chang-Soon Park, Se-Jung Yang, Yong-Heum Lee
This study aimed to evaluate the effectiveness of using low-level, low-frequency pulsed electromagnetic field (LLLF_PEMF) stimulation to improve atopic dermatitis induced by 2,4-dinitrochlorobenzene (DNCB). Twenty 6-week-old hairless mice were randomly divided into Normal (n = 5), PEMF 15 Hz (n = 5), PEMF 75 Hz (n = 5), and Sham (n = 5) groups. Following the onset of atopic dermatitis symptoms, PEMF

An Extremely Low-Frequency Vortex Magnetic Field Modifies Protein Expression, Rearranges the Cytoskeleton, and Induces Apoptosis of a Human Neuroblastoma Cell Line Bioelectromagnetics (IF 1.9) Pub Date : 2022-04-19 Diana I. Aparicio-Bautista, Daniel Chávez-Valenzuela, Giovanni Ambriz-Álvarez, Teodoro Córdova-Fraga, Juan P. Reyes-Grajeda, Óscar Medina-Contreras, Fanny Rodríguez-Cruz, Francisco García-Sierra, Patricia Zúñiga-Sánchez, Antonio M. Gutiérrez-Gutiérrez, Jaime Arellanes-Robledo, Gustavo Basurto-Islas
Homogeneous extremely low-frequency electromagnetic fields (ELF-EMFs) alter biological phenomena, including the cell phenotype and proliferation rate. Heterogenous vortex magnetic fields (VMFs), a new approach of exposure to magnetic fields, induce systematic movements on charged biomolecules from target cells; however, the effect of VMFs on living systems remains uncertain. Here, we designed, constructed
