Estimating Human Fat and Muscle Conductivity From 100 Hz to 1 MHz Using Measurements and Modelling.
Bioelectromagnetics
January 2025
The electrical conductivity of human tissues is a major source of uncertainty when modelling the interactions between electromagnetic fields and the human body. The aim of this study is to estimate human tissue conductivities in vivo over the low-frequency range, from 30 Hz to 1 MHz. Noninvasive impedance measurements, medical imaging, and 3D surface scanning were performed on the forearms of ten volunteer test subjects.

- RNA binding proteins (RBPs) are essential for gene regulation by recognizing specific RNA targets, and various methods exist to study their binding preferences, like CLIP and SELEX.
- Current methods face challenges such as the need for purified proteins and extensive sequencing, which can limit their usage.
- The proposed RNA bind-n-seq method simplifies the process by using random RNA pools and allows for multiple selection rounds, improving motif identification without needing recombinant proteins.
Background: Oxidative stress is thought to be related to many diseases. Furthermore, it is hypothesized that radiofrequency electromagnetic fields (RF-EMF) may induce excessive oxidative stress in various cell types and thereby have the potential to compromise human and animal health. The objective of this systematic review (SR) is to summarize and evaluate the literature on the relation between the exposure to RF-EMF in the frequency range from 100 kHz to 300 GHz and biomarkers of oxidative stress.

- Complex information processing systems, like the human brain, consist of specialized units that communicate locally rather than being controlled by a single global unit.
- This study focuses on decision-makers that can specialize and communicate in cyclical patterns, enabling back-and-forth information exchange.
- By adapting message-passing algorithms for local information flow, the research demonstrates that repeated communication among units can enhance performance, while an imbalance in connections and feedback can lead to suboptimal outcomes.
Background: The objective of this review is to evaluate the associations between short-term exposure to radiofrequency electromagnetic fields (RF-EMF) and cognitive performance in human experimental studies.
Methods: Online databases (PubMed, Embase, Scopus, Web of Science and EMF-Portal) were searched for studies that evaluated effects of exposure to RF-EMF on seven domains of cognitive performance in human experimental studies. The assessment of study quality was based on the Risk of Bias (RoB) tool developed by the Office of Health Assessment and Translation (OHAT).
