Temperature is an important factor in research on the biological effects of extremely low-frequency electromagnetic field (ELF-EMF), but interactions between ELF-EMF and temperature remain unknown. The effects of ELF-EMF (50 Hz, 3 mT) on the lifespan, locomotion, heat shock response (HSR), and oxidative stress (OS) of Canton-Special (CS) and mutant w1118 flies were investigated at 25°C and 35°C...

Background and Objective: Nitric Oxide in the small intestine causes relaxation of smooth muscles. Research indicates that extremely low frequency electromagnetic fields (ELF) affect nitric oxide level in the tissues. The objective of this study was to grasp the effect of prolonged exposure to ELF on the nitrergic system in the small intestine. Materials and Methods: 21 adult male rats were ...

The human papillomavirus (HPV) is the etiologic agent of cervical cancer. In this study, we provide evidence for the human Pygopus (hPygo)2 gene as a cellular biomarker for HPV-related disease. In a tumor microarray of cervical cancer progression, hPygo2 levels were greater in high-grade lesions and squamous cell carcinomas than in normal epithelia. Similarly, hPygo2 mRNA and protein levels wer...

Observing the shift to English as a Lingua Franca (ELF) in national curriculum for education, this study analyzes ELF-related features 2022 curriculum’s learning aims and evaluates their feasibility using text mining. The findings indicate that reflects ELF, example, by viewing medium of communication among diverse speakers whose first language is not English. emphasis on cultivating learners’ ...

The authors evaluated the relation between occupational exposure to extremely low frequency (ELF) magnetic fields and mortality from cardiovascular diseases. The study was based on 27,790 subjects from the Swedish Twin Registry. Exposure to ELF magnetic fields was assessed by linking occupation reported in 1967 or 1973 to a job exposure matrix. Four levels of exposure were related to cause-spec...

Previous empirical studies have demonstrated that speakers of English as a lingua franca (ELF) display flexible use various pragmatic strategies (PSs) to support effective communication. However, date few investigated PSs usage from the perspective individual ELF speakers. Supported by Vygotskian Sociocultural ontogenetic view on pragmatics, this paper offers two qualitative case exploring firs...

OBJECTIVES When evaluating the pharmacodynamics of antimicrobials, assumptions are often made relative to their pharmacokinetics. One example of this is applying tissue penetration results of uninfected hosts to those displaying a targeted illness. As tigecycline evolves into a potential treatment option for pneumonia, we determined whether the presence of a lung infection affected the penetrat...

The composition of simple behaviors is a common practice to obtain complex behaviors from autonomous agents. In this paper, we present S-ELF, a reinforcement learning approach that learns to coordinate pre-defined basic behaviors and is derived from ELF (Evolutonary Learning of Fuzzy rules) (Bonarini, 1993), (Bonarini, 1996a). S-ELF (Symbolic ELF) learns the context of activation for each of th...

BACKGROUND AND AIMS Chronic liver diseases are characterized by inflammatory and fibrotic liver injuries that often result in liver cirrhosis with its associated complications such as portal hypertension and hepatocellular carcinoma. Liver biopsy still represents the reference standard for fibrosis staging, although transient elastography is increasingly used for non-invasive monitoring of fibr...

Whether exposure of humans to extremely low frequency electromagnetic fields (ELF-EMF) can cause cancer is controversial and therefore needs further research. We used a Friend erythroleukemia cell line that can be chemically induced to differentiate to determine whether ELF-EMF could alter proliferation and differentiation in these cells in a manner similar to that of a chemical tumor promoter....
