The countless increase in towers and mobile phones has increased the amount of non-ionizing radio waves in surroundings during last two decades. Several reports have revealed non-desirable after effects of mobile phone frequency electromagnetic field radiations at cellular level. Thus, the present study was designed to evaluate the effect of cellphone frequency electromagnetic field (EMF) radia...
OBJECTIVE Endomyocardial fibrosis (EMF) is a rare disease and is often an underdiagnosed and forgotten cardiomyopathy. The objective of this study was to document the current frequency of EMF in Sudan by defining and selecting cases from patients attending the echocardiography laboratory. Additionally we aimed to create an EMF registry for Sudan. METHODS The study started in January 2007 and ...
OBJECTIVE New investigations are in progress to find some alternative treatments for diabetes mellitus. Herbs are some of the interesting medications in this regard. Cynodon dactylon (C.d) is a potential plant to be considered as a new medication. On the other hand, the effect of the Electromagnetic Field (EMF) on bio organisms is becoming clearer. In this study, the effect of C.d, EMF and insu...
BACKGROUND The overall evidence for adverse health effects of electromagnetic fields (EMF) at levels of exposure normally experienced by the public is generally considered weak. However, whether long-term health effects arise remains uncertain and scientific policy advice is therefore given against a background of uncertainty. Several theories exist about different roles that experts may take w...
The electromagnetic field (EMF) has an effect on various organs, including the female reproductive system. purpose of this study was to evaluate impact carnosine ovarian follicle number and diameter in rats exposed a 900 Megahertz (Mhz) field. In study, six different groups were used. 40 divided into evaluated. ovaries removed at end study. Routine histological procedures performed tissues. Fol...
OBJECTIVE To investigate the single and combined effects of electromagnetic field (EMF) exposure and the insulin growth factor-I (IGF-I) on proteoglycan (PG) synthesis of bovine articular cartilage explants and chondrocytes cultured in monolayers. DESIGN Bovine articular cartilage explants and chondrocyte monolayers were exposed to EMF (75Hz; 1.5mT) for 24h in the absence and in the presence ...
With the rapid increase in the number of mobile phone users, the potential adverse effects of the electromagnetic field radiation emitted by a mobile phone has become a serious concern. This study demonstrated, for the first time, the blood-brain barrier and cognitive changes in rats exposed to 900 MHz electromagnetic field (EMF) and aims to elucidate the potential molecular pathway underlying ...
On July 23, 2001, new safety limits for occupational exposure to electromagnetic fields (EMF) were introduced in Poland. The limits have been based on the analysis of international recommendations, e.g., ICNIRP (1998), WHO (1998), IEEE standard (1999), drafts of European standards (ENV 1995), and a critical review of the world literature on the biological effects of EMF and health effects of ex...
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 ...
Ectomycorrhizal fungi (EMF) form symbioses with a few plant species that comprise a large fraction of the arctic vegetation. Despite their importance, the identity, abundance and distribution of EMF in the Arctic, as well as the key drivers controlling their community composition are poorly understood. In this study, we investigated the diversity and structure of EMF communities across a biocli...
