An overview contains the analysis of controversial literary data on possible therapeutic and pathogenic effects of electromagnetic fields on humans. The non-specific character of body shifts induced by electromagnetic fields with a prevalence of adaptive reactions at the onset and an emergence of dysadaptive processes during extremely long exposure was displayed. The leading role in the development of a therapeutic or pathogenic effect is played by the functional characteristics of an individual postulating the interaction of cumulative and adaptive processes in the body during long-term exposure in an electromagnetic field.

We describe a magnetic relation in analogy to the well-known dielectric Lyddane-Sachs-Teller relation [R. H. Lyddane et al.

However, most chiral metasurfaces are generally composed of complex chiral meta-atom structures, and few design schemes are developed to dynamically tune the chiroptical response. Here, we experimentally demonstrated an effective strategy to design achiral metasurfaces based on the extrinsic chirality of all-dielectric nanodisks arranged in a square array.

The use of neurostimulation devices for the treatment of Alzheimer's disease (AD) is a growing field. In this review, we examine the mechanism of action and therapeutic indications of these neurostimulation devices in the AD process. Rapid advancements in neurostimulation technologies are providing non-pharmacological relief to patients affected by AD pathology.

Pathologies such as mesenteric artery ischemia and reperfusion (MIR) can lead to many organ dysfunctions, including the brain and heart through damage mechanisms induced in response to hypoxic conditions. Radiofrequency electromagnetic field (RF-EMF) can increase the vascularization of tissues by providing endothelial nitric oxide synthase (eNOS)-mediated nitric oxide (NO) release from the endothelium. The aim of this study is to investigate the protective effect and mechanism of RF-EMF in ischemic intestinal injury in the experimental MIR model.

The enhancement magnitude of the electromagnetic effects has consistently ranked among the highest research priorities in Surface-enhanced Raman scattering (SERS). This study introduces a novel facile synthesis method for zinc oxide nanorice (ZnONR) decorated with small silver particles (ZnONR-Ag). The semiconductor-noble nanomaterial is designed to enhance sensitivity and reproducibility when detecting isoprocarb (IPC) and crystal violet (CV) at trace levels using SERS.
