  • A comprehensive mechanism of biological and health effects of anthropogenic extremely low frequency and wireless communication electromagnetic fields

    Open AccessDimitris J Panagopoulos, Igor Yakymenko et al.ARTICLEFrontiers in Public Health2025

    Exposure to anthropogenic electromagnetic fields (EMFs), especially those of wireless communications (WC) has increased tremendously. This is an unprecedented phenomenon throughout biological evolution because, all anthropogenic EMFs, being fully polarized, coherent, and, especially WC EMFs, highly variable, differ substantially from the natural EMFs. WC EMFs consist of Microwave (MW) carrier waves, modulated, by Extremely Low Frequency (ELF) sig…

  • Soft Tissue Ewing Sarcoma Cell Drug Resistance Revisited

    Open AccessSeyedehsadaf Asfa, Halil Ibrahim Toy et al.ARTICLEInternational Journal of…2023

    Ewing sarcoma is a rare type of cancer that develops in the bones and soft tissues. Drug therapy represents an extensively used modality for the treatment of sarcomas. However, cancer cells tend to develop resistance to antineoplastic agents, thereby posing a major barrier in treatment effectiveness. Thus, there is a need to uncover the molecular mechanisms underlying chemoresistance in sarcomas and, hence, to enhance the anticancer treatment out…

  • Associations between Maternal and Offspring Hair Cortisol Concentrations and Child Behavioral Symptoms in Mother-Child Pairs with Perinatal Mental Disorders

    Open AccessAnna Agapaki, Fenia Papagianni et al.ARTICLEChildren2022

    Maternal perinatal mental disorders (PMD) are associated with developmental and behavioral problems in children, probably mediated by the programming of the hypothalamic-pituitary-adrenal (HPA) axis. Increased cortisol concentrations during the antenatal and perinatal periods have been related to long-term effects on children's behavior and stress response. We aimed to investigate the association of hair cortisol concentrations (HCC) between moth…

  • Could Covid-19′s Aftermath on Children’s Health Be Felt into the 22nd Century

    Open AccessAlexios‐Fotios A Mentis, George Paltoglou et al.ARTICLEChildren2022

    The COVID-19 pandemic has massively affected people's health, societies, and the global economy. Our lives are no longer as they were before COVID-19, and, most likely, will never be the same again. We hypothesize that the effect of the COVID-19 pandemic on population health and the economy will last for a very long time and will still be felt in the 22nd century. Our hypothesis is based on evidence from the 1918-1919 influenza pandemic, the Dutc…
