Childhood acute leukaemia (AL) etiology is still largely unknown. The main environmental exposures currently investigated are exposures to pesticides, hydrocarbon, ionizing and non ionizing radiation. The Geocap program investigates potential links between Childhood AL and several environmental exposures, among which domestic exposure to radon. The Geocap approach consists in the comparison of ...

AIMS This article is a convenient overview to assist the interested echocardiographist towards acquiring his own experience in the field of myocardial perfusion imaging using intravenous contrast agents. This goal is now pursued in many centres, since contrast echo holds the advantages of cardiac ultrasound (non-invasiveness, high spatial and temporal resolution, wide availability, use of non-i...

generating stations, distribution lines, high voltage (HV) lines, and electric appliances. Increased speed of urbanization and per capita increase in the utilization of electricity is forcing all kinds of living bodies to be exposed to electromagnetic environment created by man-made sources. To meet the increased demands, electric power generation, distribution, and transmission networks are al...

Ionizing radiations induce a variety of molecular and cellular types of damage in mammalian cells as a result of energy deposition by the radiation track. In general, tracks are divided into two classes of sparsely ionizing ones such as electron tracks and densely ionizing tracks such as heavy ions. The paper discusses various aspects and differences between the two types of radiations and thei...

If massive stars form by disk accretion, then bipolar outflows should be generated as in the case of low-mass star formation. High accretion rates lead to high outflow rates and make the wind density very large near the protostar. We therefore predict that massive protostars have very small, jet-like H II regions confined by their outflows; we identify these H II regions with “hypercompact” (≤ ...

Kinematic parameters were evaluated in mouse epididymal extracts to monitor maturation of sperm movement in animals exposed to static magnetic fields using the Sperm-Class Analyzer computerized image analysis system. For this purpose, animals were exposed to a field of 0.7 T generated by a permanent magnet over 10 or 35 days for either 1 or 24 hr/day. The values of the motion endpoints were sim...

Increased exposure to electromagnetic fi elds such as radio frequencies used by Wifi technology raise questions and concerns about their impact on health. For answer these questions, several scientifi c studies have carried out followed by results publication in prestigious scientifi c revues. Literature conducted on the effects of non-ionizing radiation and Wifi waves is vast and sometimes con...

Modern age exposes humans to an increasing level of electromagnetic activity in their environment due to overhead power lines and transformers around residential areas. Studies have shown that treatment with antioxidants can suppress the oxidative damage induced by electromagnetic fields in various frequencies of the non-ionizing radiation band. In this study, we detected protein carbonyl conte...

The genotoxic effects of occupational exposure to ionizing and non-ionizing radiation were investigated in 25 physicians and nurses working in hospitals and in 20 individuals working at radio-relay stations. Examination was conducted by chromosome aberration analysis of peripheral blood lymphocytes. The data showed that total number of chromosome aberrations in people exposed to ionizing and ra...

Endometriosis is the presence of endometrial tissue outside the uterine cavity(1-3). This endometrial tissue may be located in the ovaries as endometriomas and/or as extraperitoneal/subperitoneal implants(3,4). When implant depth is greater than 5 mm, condition is referred to as deep endometriosis(3,4). It represents a common cause of pelvic pain and infertility in young women(1-3). Surgery rem...
