Summary: Exposure to 900 MHz radiofrequency fields can increase ROS levels and induce a transient UPRmt in BMSC cells, which is reversed within 24 hours post-exposure. More research is needed to understand the detailed molecular mechanisms of RF-induced UPRmt.

Summary: The study aimed to investigate the impact of mobile phone-like radiofrequency radiations (RFR) on the tibia and skeletal muscle health. It was found that RFR emitted from mobile phones may have adverse effects on the tibia and skeletal muscle, but further studies are required for confirmation.

Summary: This study assessed the balance between cell death and proliferation and investigated the involvement of the JNK/p38 MAPK signaling pathway in the testis of rats exposed to 900 MHz RFR. The results showed that RFR might result in alterations during acute period exposure for several parameters, but this can be ameliorated in the chronic period in rat testis. The study also reported the involvement of the p38/JNK-mediated MAPK pathway after exposure to 900 MHz RFR.

Summary: This article proposes a wireless control architecture that allows the execution of MPPT algorithms for multiple PV subsystems, achieving flexibility and optimal energy production. Wireless communications are implemented using XBee 900 MHz RF modules, providing a low cost solution with long range communication. Sliding Mode Control (SMC) was selected as the control technique and proved to provide better performance and robustness compared to conventional techniques.

Summary: In this study, the radiation responses of silicon photonic passive devices in silicon-on-insulator technology were investigated. High-energy neutron and Co-60 gamma-ray irradiation caused blue shifts in the wavelengths of micro-ring resonators and Mach-Zehnder interferometers. The devices with SiO2 upper cladding layer exhibited strong tolerance to irradiation.

Summary: This study evaluated the effects of long-term prenatal exposure to EMF radiation at different frequencies on the myocardium of rats. The results showed that high-frequency EMF radiation causes greater damage to the myocardium, accompanied by an increase in malondialdehyde levels and a decrease in glutathione levels.

Summary: The study found no evidence of early changes in miRNA expression levels in human whole blood cells after 900 MHz EMF exposure, nor were EMF-responsive individuals identified. Different miRNA expression levels after EMF exposure were not reproducible after 2 years, indicating a lack of consistent effects over time.

Summary: The study revealed that RG1 enhances the paracrine effects of BM-MSCs by partially upregulating HO-1, leading to improved survival and intestinal damage in irradiated animals. The superior paracrine efficacy of RG1-MSC-CM is related to increased release of VEGF and IL-6, which improve intestinal proliferation, apoptosis, inflammation, angiogenesis, and stem cell regeneration in a HO-1 dependent mechanism.

Summary: Adaptive temperature control is proposed to increase the nonthermal exposure level of in vitro experiments. By regulating air temperature, it can double the maximum SAR to trigger and characterize nonthermal effects. This method proves effective in suppressing temperature variances in cells and increasing exposure levels.

Summary: This study evaluated the inactivation efficiency of essential oils on E. coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes in buffered peptone water and hot-chili sauce when coupled with microwave heating. The results showed that the combination of carvacrol and microwave heating for 45 seconds had the most effective inactivation for the pathogens. This method can effectively inactivate the pathogens while ensuring food safety.

Summary: This study investigated the influence of microwave on the dynamic mechanical properties of basalt through experimental tests and characterized the thermal damage using non-destructive testing and nuclear magnetic resonance technology. The results showed that increasing the microwave power and exposure time led to a continuous decrease in the P-wave velocity, dynamic compressive strength, and elastic modulus of basalt, and the dynamic failure mode tended to become more complex fractures.
