Increasing use of mobile phones creates growing concerns regarding harmful effects of radiofrequency nonionizing electromagnetic radiation on human tissues located close to the ear, where phones are commonly held for long periods of time. We studied 20 subjects in the mobile-phone group who had a mean duration of mobile phone use of 12.5 years (range 8-15) and a mean time use of 29.6 h per mont...

The use of mutagenis to produce strains with desired characteristics including increased biosynthetic capacity is an established part of industrial research (Stauffer and Backus, 1954; Dulaney, 1955; Backus and Stauffer, 1955). Publications indicate that much of this work has been done with ionizing and nonionizing radiation. The mutagenic effect of mustard gas for Drosophila spp. (Auerbach et ...

The biologic effect of an electromagnetic field of a frequency of 2375 +/- 50 MHz was studied in rats and rabbits in specially constructed absorbant chambers. The results of the investigations have shown that microwave radiation of 10, 50, 500 mu W/cm2 for 30 days, 7 hr/day, causes a number of changes in bioelectric brain activity and also in behavioral immunological, and cytochemical reactions...

Background and Objective: Knee joint is the complex joint. It much frequently injured due to trauma. The principle intra articular structures in knee are 2 cruciate ligaments, menisci collateral ligaments. main objective study MRI findings ligament injuries of Materials Methods: 110 patients with suspected was performed on 1.5-T MR system using flexible surface coil. Results: A total a period y...

Photoacoustic imaging (PAI) has the potential for real-time molecular imaging at high resolution and deep inside the tissue, using nonionizing radiation and not necessarily depending on exogenous imaging agents, making this technique very promising for a range of clinical applications. The fact that PAI systems can be made portable and compatible with existing imaging technologies favors clinic...

We have demonstrated that grape seed proanthocyanidins (GSPs) could effectively scavenge hydroxyl radical (•OH) in a dose-dependent manner. Since most of the ionizing radiation- (IR-) induced injuries were caused by •OH, this study was to investigate whether GSPs would mitigate IR-induced injuries in vitro and in vivo. We demonstrated that GSPs could significantly reduce IR-induced DNA strand b...

I presume I have been awarded the honor of chairing and introducing this session because I have been in mutation research for over three decades and thus can see the links between the present findings and aims in this field and those of earlier periods. It is true that my own research has been mainly concerned with chemical mutagenesis, but one of the exciting aspects of modern mutation researc...

The purpose of this study is to evaluate the nonionizing radiation (NIR) exposure, especially optical radiation levels, and potential health hazard from aluminum arc welding processes based on the American Conference of Governmental Industrial Hygienists (ACGIH) method. The irradiance from the optical radiation emissions can be calculated with various biological effective parameters i.e., S( ),...

Methylazide photolysis at 248 nm has been investigated by ionizing photofragments with synchrotron radiation in a photofragmentation translational spectroscopy study. CH3N and N2 were the only observed primary products. The translational energy release suggests a simple bond rupture mechanism forming singlet methylnitrene, 1CH3N, and N2. Thus, these experiments reveal the unimolecular decomposi...
