The goal of this study was to investigate whether glucocorticoids (GCs) take part in cognition impairment after exposure to chronic low-power-density microwave (MW) fields. We exposed Wistar rats to a 2.45-GHz pulsed MW field at an average power density of 1 mW/cm(2) for 3 h daily, for up to 30 days. Our results show that MW-exposed rats had significant deficits in spatial learning and memory p...

Oral rabies vaccination (ORV) baiting programs for control of raccoon (Procyon lotor) rabies in the USA have been conducted or are in progress in eight states east of the Mississippi River. However, data specific to the relationship between raccoon population density and the minimum density of baits necessary to significantly elevate rabies immunity are few. We used the 22-km2 US National Aeron...

background : due to rapid advances in modern technologies such as telecommunication technology, the world has witnessed an exponential growth in the use of digital handheld devices (e.g. smartphones and tablets). this drastic growth has resulted in increased global concerns about the safety of these devices. smartphones, tablets, laptops, and other digital screens emit high levels of short-wave...

BACKGROUND Bone toxicity has been linked to organochlorine exposure following a few notable poisoning incidents, but epidemiologic studies in populations with environmental organochlorine exposure have yielded inconsistent results. OBJECTIVES The aim of this study was to investigate whether organochlorine exposure was associated with bone mineral density (BMD) in a population 60-81 years of a...

PURPOSE This study aims to assess the association of sunlight exposure with breast cancer risk, measured by the breast density assessed from Tabár's mammographic pattern in Chinese women. METHODS A total of 676 premenopausal women were recruited to participate in this study, in which 650 completed a validated sunlight exposure questionnaire via telephone. The mammograms were classified accord...

all living organisms are exposed to ionizing radiation comprising cosmic rays coming from outer space, terrestrial nuclides occurring in the earth’s crust, building materials, air, water and foods and in the human body itself. the exposures are constant and uniform for all individuals everywhere including the dose from ingestion of 40k in food. cosmic rays are, more intense at higher altitudes,...

introduction:. nickel (ni) is one of the toxic heavy metals that exposure to it has been connected with chronic respiratory complications such as asthma, chronic bronchitis, lung cancer and heart diseases .. in this research,  original studies that investigated occupational or environmental exposures to nickel and  measured nickel levels in human tissues was reviewed. materials and methods: in ...

testicular cancer is one of the commonest cancers in men of working age, and is increasing in incidence in europe and north america. one suggested mechanism of causation is that there is impaired differentiation of germ cells in the pre- or perinatal period, followed by malignant transformation in later life, possibly by a hormonal mechanism. endocrine disrupting chemicals (edcs) have been a ma...
