Summary: During the past decades, the potential effects of extremely low-frequency electromagnetic fields (ELF-EMFs) on human health have gained significant attention worldwide. While there have been guidelines for magnetic field limits, further research is needed to explore the long-term effects of ELF-EMFs on organisms and systems, particularly the induced electrotherapy and potential impacts on human health under different frequencies and fields. This article systematically reviews the in vivo experimental outcomes and corresponding mechanisms to provide insights into the safety considerations of ELF-EMFs and advance the future application of electrotherapy in human health.

Summary: This study used numerical simulations to investigate the far-field absorption of radio frequency electromagnetic fields (RF-EMFs) by different types of insects at frequencies ranging from 2 to 120 GHz, which are expected to be used in future wireless communication. The results showed that the absorbed power is related to the size and frequency, and a log-linear model was developed to estimate the absorbed power in insects. In addition, there was a high correlation between the absorbed power predicted by anatomically accurate insect models and those predicted by spheroid models within a certain frequency range.

Summary: Cell phones expose significant parts of the human brain and head to extremely low frequency (ELF) magnetic fields (MF) classified by the IARC as a 2B carcinogen. Measurements and simulations showed that the ELF MF emitted by cell phones can reach levels comparable to those known to induce biological and health effects, including carcinogenesis. Understanding the exposure and combined effects of radiofrequency and ELF electromagnetic fields is important for future studies.

Summary: Research shows that exposure to 50 Hz electromagnetic fields can significantly impact the wingbeat frequency of locusts in a field strength-dependent manner, with effects varying based on the locust's initial frequency. During exposure to 50 Hz EMFs, locusts had their wingbeat frequencies entrained to a 2:5 ratio of the applied EMF cycles. Moreover, exposure to ELF EMFs near normal wingbeat frequency caused locusts to synchronize with the exact frequency of the applied field.

Summary: This study investigates the regulation of 15 Hz/2 mT ELF-EMFs on long-term potentiation (LTP) persistence in the hippocampal CA1 region of Sprague-Dawley rats at different early developmental stages. The results show that ELF-EMFs differentially inhibit LTP persistence depending on the age, with a stronger inhibitory effect in younger rats. The inhibitory effect is associated with intracellular calcium stores mediated by inositol-1,4,5-trisphosphate receptors (IP(3)Rs), and can be modulated by adjusting extracellular calcium concentration.

Summary: This study suggests that cannabinoid agonists, specifically the CB1R agonist WIN, may not be effective in treating cerebellar ataxia and may even worsen symptoms. However, co-administration of the CB1R antagonist AM251 with WIN can prevent some ataxic symptoms. This indicates that cannabinoid modulation of ataxia symptoms may involve other cannabinoid receptors in addition to CB1Rs.

Summary: This study found that antigen B from hydatid cyst fluid could reduce the levels of anti-inflammatory cytokines in rats with experimental autoimmune encephalomyelitis (EAE)-induced multiple sclerosis (MS) and increase nerve conduction velocity. The results showed that antigen B modulated the immune system and reduced the inflammatory component of the EAE MS animal model, leading to a decrease in symptoms at the behavioral and electrophysiological level. Antigen B could be used as a potential therapeutic agent to regulate the immune system in MS patients.

Summary: Maternal morphine exposure reduces motivation for cognitive tasks and leads to deficits in attention, accuracy, and executive function. It also induces depression-like behaviors and has negative consequences for learning and memory in offspring. Maternal separation can cause behavioral and neuropsychiatric abnormalities later in life. This study aimed to evaluate the effects of chronic morphine consumption and maternal separation on the cognitive and behavioral performance of male adolescent rats. The results showed that maternal separation increased locomotor activity and movement velocity, while morphine exposure worsened body stretching behavior. Maternal separation also resulted in spatial learning deficits, but recognition and spatial memory were not significantly affected. Overall, these findings suggest that maternal morphine exposure and maternal separation can impair cognitive and behavioral performance in adolescent male rats.

Summary: Prenatal stress (PS) can lead to behavioral disorders in offspring, such as substance abuse and anxiety. This study investigated the effects of agmatine on cognitive outcomes in male mice exposed to PS and molecular changes in the ventral tegmental area (VTA). The results showed that agmatine reduced locomotor activity impairment and conditioned place preference to morphine in PS offspring. Agmatine also improved anxiety-like behavior and drug-seeking behavior induced by PS. The molecular effects were observed in the VTA, with agmatine reducing enhanced brain-derived neurotrophic factor (BDNF) levels. Overall, prenatal treatment with agmatine protected against the negative consequences of PS on the development of affective circuits in offspring.
