In the last three decades, a large number of studies have been arisen, which dealt with the effects of electromagnetic fields (EMFs) in biological systems (Aaron & Ciombor, 1993; Tao & Henderson, 1999; Tofani et al., 2002b; Walker et al., 2007). The EMFs have been used in very important technological applications that concern in diagnosis (e.g. MRI, X-rays, CT). A part of scientific community t...

Modern civilization is an electromagnetic one. Low frequency electromagnetic fields (EMFs) showed to exert quite subtle biologic effects as a consequence of continuous exposure of living beings to their influence and the summing up of their otherwise limited impact. If high frequency and microwave EMFs are now considered potentially dangerous due to some controversial experimental results and c...

The relationship between exposure to electromagnetic fields (EMFs) and human health is more and more in focus. This is mainly because of the rapid increasing use of such EMFs within our modern society. Exposure to EMFs has been linked to different cancer forms, e.g. leukemia, brain tumors, neurological diseases, such as Alzheimer's disease, asthma and allergy, and recently to the phenomena of '...

Red light (c. 630 nm) is almost universally used in tumour phototherapy as it is the most penetrating of the porphyrin excitation wavebands. However, measurements of tumour attenuation of light of different wavelengths and of the excitation spectrum of haematoporphyrin derivative in vitro suggested that green light might be more efficient than red in destroying thin tumours. Experimentally, we ...

Electrical power lines are ubiquitous in the developed world and in urban areas of the developing world. All electrical currents, including those running through power lines, generate electric and magnetic fields (EMFs). Electrical power lines, towers,and distribution poles are used by birds for perching, hunting, and nesting. Therefore, many bird species, like humans, are exposed to EMFs throu...

Despite the high potential of endohedral metallofullerenes (EMFs) for application in biology, medicine and molecular electronics, and recent efforts in EMF synthesis, the variety of EMFs accessible by conventional synthetic methods remains limited and does not include, for example, EMFs of late transition metals. We propose a method in which EMF formation is initiated by electron irradiation in...

Blood is a fluid connective tissue of human body, where it plays vital functions for the nutrition, defense and well-being of the organism. When circulating in peripheral districts, it is exposed to some physical stresses coming from outside the human body, as electromagnetic fields (EMFs) which can cross the skin. Such fields may interact with biomolecules possibly inducing non thermal-mediate...

Wound healing is a highly coordinated and complex process involving various cell types, chemical mediators and the surrounding extracellular matrix, resulting in a tightly orchestrated re-establishment of tissue integrity by specific cytokines. It consists of various dynamic processes including a series of overlapping phases: inflammation, proliferation, re-epithelialization and remodeling. One...

This paper applies and extends resource dependence theory (RDT) to comparatively investigate major factors that determine the level of cross-border mergers and acquisitions (M&As) by emerging market firms (EMFs) in developed and developing markets. We argue that the resource dependence logic of M&As (or simply the M&A logic) provides a unique perspective in better understanding the internationa...

This study evaluated frequency-dependent effects of extremely low frequency electromagnetic fields (ELF-EMFs) on melanogenesis by melanocytes in vitro. Melanocytes were exposed to 2 mT EMFs at 30-75 Hz for 3 days before melanogenesis was examined. Exposure to ELF-EMFs at 50 and 60 Hz induced melanogenic maturation without cell damage, without changing cell proliferation and mitochondrial activi...
