Rosmarinic acid belongs to the group of polyphenols; it has antioxidant, anti-inflammatory and antimicrobial activities and help to prevent cell damage caused by free radicals. The objective was to study the effect of Rosmarinic acid on sertolli cells apoptosis and serum antioxidant levels in rats after they were exposed to electromagnetic fields. Male Wistar rats (n=40) were allocated into thr...

introduction: electromagnetic fields (emfs) can influence the biological system by the formation of free radicals in cells. the emfs are able to deteriorate defense system against free radicals that leads to oxidative stress (os). lipid peroxidation process (lpo) is an index of oxidative stress, and the malandialdehyde (mda) is the final product of lpo. vitamin e is the most important antioxida...

Electromagnetic fields (EMFs) have been increasingly used as an alternative or adjunctive treatment option for musculoskeletal disorders (MSDs) like fractures, arthritis and osteoporosis. The electromagnetic based treatments can be divided into four main groups based on their physical characteristics and consequent biological effects: Direct current, capacitive coupling, inductive coupling (pul...

BACKGROUND There are about 1.6 billion GSM cellular phones in use throughout the world today. Numerous papers have reported various biological effects in humans exposed to electromagnetic fields emitted by mobile phones. The aim of the present study was to advance our understanding of potential adverse effects of the GSM mobile phones on the human hearing system. METHODS Auditory Brainstem Re...

Many higher animals have evolved the ability to use the Earth's magnetic field, particularly for orientation. Drosophila melanogaster also respond to electromagnetic fields (EMFs), although the reported effects are quite modest. Here we report that negative geotaxis in flies, scored as climbing, is disrupted by a static EMF, and this is mediated by cryptochrome (CRY), the blue-light circadian p...

This study was conducted to investigate the effects of extremely low frequency electromagnetic fields (EMF) on signal pathway in plasma membrane of cultured cells (RAW 264.7 cells and RBL 2H3 cells), by measuring the activity of phospholipase A(2) (PLA(2)), phospholipase C (PLC) and phospholipase D (PLD). The cells were exposed to the EMF (60 Hz, 0.1 or 1 mT) for 4 or 16 h. The basal and 0.5 µM...

Background: In recent years, the widespread use of microwave producing instruments specially mobile phones; result in growing concern regarding the possible effects associated with these waves on human health. Some studies highlight the possible health hazards of electromagnetic fields (EMF), while others contest the hypothesis of biological impact of EMF. The aim of this study was to evaluate ...

A cranial window method modified for our experiment enabled to observe the cerebral microcirculation including the hemodynamic changes, the leukocyte behavior, and the blood-brain barrier(BBB) function during preand postexposure to radio-frequency electromagnetic fields (EMF) with a loop antenna in rats. No noticeable changes in the BBB function, the diameter of venule, and the number of sticki...

BACKGROUND Studies investigating the effect of power frequency (50-60 Hz) electromagnetic fields (EMF) on melatonin synthesis in rats have been inconsistent with several showing suppression of melatonin synthesis, others showing no effect and a few actually demonstrating small increases. Scant research has focused on the ensuing sleep patterns of EMF exposed rats. The present study was designed...

Aiming to investigate the possibility of electromagnetic fields (EMF) developed by nonionizing radiation to be a noxious agent capable of inducing genotoxicity to humans, in the current study we have investigated the effect of 910-MHz EMF in rat bone marrow. Rats were exposed daily for 2 h over a period of 30 consecutive days. Studying bone marrow smears from EMF-exposed and sham-exposed animal...
