Background: This study was planned to examine the effects of whole-body exposure to GSM-950 MHz electromagnetic fields (EMFs) on acquisition and consolidation of spatial memory in rats using a water maze task. Materials and Methods: In experiment 1, the animals were given two blocks of five trials per day for three consecutive days in a water maze task. The interval between blocks was 4h...
Chironomus riparius larvae (3rd-4th instar) were extremely resistant to waterborne Cd with 48h LC50s of 331 mg Cd/L in soft water (10 mg/L Ca CO(3)) and 1106 mg Cd/L in moderately hard (140 mg CaCO(3)/L) water. Unexposed larvae had whole body Ca and Na concentrations of 11.2(0.3) and 84.5(3.0) micromol/g, respectively. The larvae exposed through acute toxicity tests accumulated massive amounts ...
2 JUNE 2015 I n [Fingar, 2008], the US National Intelligence Council reported six potentially disruptive technologies for the year 2025, one of them being service robotics. The report states that, “[...] robots for elder care applications and the development of human augmentation technologies, mean that robots could be working alongside humans in looking after and rehabilitating people.” On a r...
The possibility that the exposure of organisms to whole-body hyperthermia may provide protection against subsequent thermal exposures is intriguing and may play an important role in the clinical scheduling of fractionated hyperthermia. We used C3H mice to investigate whether whole-body heating can be used as a conditioning treatment to induce protection of mice against thermal death from a subs...
Background: Vibration as one of the harmful physical factors is relatively present in a wide range of jobs. Musculoskeletal disorders (MSDs) are among the most prevailing complaints of workers encountering occupational factors for example vibration. Therefore, this study was conducted to investigate vibration and its association with the MSDs in upper limbs of heavy mine vehicles drivers. Ma...
Nowadays, using rail vehicles like metro is necessary for transportation in megacities and metropolises. In this descriptive-analytical study, whole body vibration was evaluated by two methods including basic evaluation and the recommended dose of vibration proposed based on ISO 2631-1 standard. In the present study measurements were performed over 13000 seconds in usual daily working hours by ...
Objective(s) The possible risks of radio-frequency electromagnetic fields (EMF) for the living organisms and human body are a growing concern for our society. In this study, we examined the possibility of changes in working memory and hippocampal histological characteristics effects in mice brain following whole body exposure to microwave radiation. Materials and Methods During gestation per...
