abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...

[1] Experimental observations of ELF/VLF waves generated using the dual‐beam heating capability of the High frequency Active Auroral Research Program (HAARP) HF transmitter in Gakona, Alaska, are compared with the predictions of an ionospheric HF heating model that accounts for the simultaneous propagation and absorption of multiple HF beams. The model output is used to assess three properties ...

background: the extremely low-frequency electromagnetic field (elf-emf), mainly emitted by electric transmission lines and household electronic appliances, is becoming a worldwide health risk. it is imperative to investigate the biological impacts of elf-emf and to identify products that are resistant to the radiation from 50 hz elf-emf. in this study, we investigated the biological impacts of ...

AIM There is a specific frequency of extremely low-frequency electromagnetic field (ELF-EMF) that promotes neuronal differentiation. Although several mechanisms are known to regulate ELF-EMF-induced neuronal differentiation, a key factor that mediates neurogenic potentials by the ELF-EMF is largely unknown. Also, the potential use of ELF-EMF exposure in cell transplantation assays is yet to be ...

BACKGROUND Noninvasive tools to diagnose nonalcoholic fatty liver disease (NAFLD), including transient elastography (TE) and enhanced liver fibrosis panel (ELF), have only been evaluated in children with biopsy-proven NAFLD. We evaluated the prevalence of ELF and TE abnormalities in obese children without clinical liver disease and examined the effects of BMI stabilization on ELF and TE in a lo...

Objective(s): It is known that extremely low frequency-pulsed electromagnetic fields (ELF-PEMF) influence multiple cellular and molecular processes. Retinal pigment epithelial (RPE) cells have a significant part in the emergence and pathophysiology of several ocular disorders, such as neovascularization. This study assessed the impact of ELF-PEMF on the proangiogenic features of RPE cells. Mate...

We have shown that loss of ELF, a stem cell adaptor protein, disrupts TGF-b signaling through Smad3 and Smad4 localization. Notably elf +/ /smad4 mice develop gastric cancer presenting this as an important model for analyzing molecular event in gastric carcinogenesis. To gain further insight into the functional role of ELF in gastric cancer suppression, we carried out a detailed characterizatio...

background: rapidly increasing possibilities of exposure to environmental extremely low-frequency electromagnetic fields (elf-emf) have become a topic of worldwide investigation. epidemiological and laboratory studies suggest that exposure to elf-emf may increase cancer risk therefore assessment of chromosomal damage in various cell lines might be of predictive value for future risk estimation....

Extremely low-frequency electromagnetic fields (ELF-EMF) causes various biological effects through altering intracellular calcium homeostasis. The role of high voltage-gated (HVA) calcium channels in ELF-EMF induced effects has been extensively studied. However, the effect of ELF-EMF on low-voltage-gated (LVA) T-type calcium channels has not been reported. In this study, we test the effect of E...

Background: Rapidly increasing possibilities of exposure to environmental extremely low-frequency electromagnetic fields (ELF-EMF) have become a topic of worldwide investigation. Epidemiological and laboratory studies suggest that exposure to ELF-EMF may increase cancer risk therefore assessment of chromosomal damage in various cell lines might be of predictive value for future risk es...
