Presence of multidrug resistant bacteria on mobile phones of healthcare workers accelerates the spread of nosocomial infection and regards as a threat to public health in Bangladesh
Publication date: Available online 6 October 2017 Source:Journal of Microscopy and Ultrastructure Author(s): Tonmoy Debnath, Shukanta Bhowmik, Md. Tarequl Islam, Mohammad Mehadi Hassan Chowdhury Recently, mobile phones have become a potent vector for the transmission of pathogens. In hospitals, the use of the mobile phones by healthcare workers in an unhygienic manner accelerate the spread of nosocomial infection. We aimed to investigate the prevalence of microbiological contamination of mobile phones belonging to clinicians in Bangladesh hospitals. From 100 samples, we identified 69 isolates of bacteria including 22...

Does omega-3 have a protective effect on the rat adrenal gland exposed to 900MHz electromagnetic fields?
Publication date: Available online 21 September 2017 Source:Journal of Microscopy and Ultrastructure Author(s): Adem Kocaman, Mehmet Gül, Kıymet Kübra Yurt, Gamze Altun, Emrah Zayman, Elfide Gizem Kıvrak The aim of this study was to investigate the harmful effects of exposure to 900-megahertz (MHz) electromagnetic fields (EMF) and the protective effects of omega-3 (Omg-3) against EMF in the rat adrenal gland. Eighteen Wistar albino rats were randomly assigned into three groups, control (Cont), EMF, and EMF+Omg-3. The EMF and EMF+Omg-3 groups both consisted of six rats exposed to an EMF of 900MHz for 60min/day f...

Effects of 900-MHz radiation on the hippocampus and cerebellum of adult rats and attenuation of such effects by folic acid and Boswellia sacra
This study was conducted to evaluate the effects of exposure to the 900-MHz radiation electromagnetic fields (EMF) emitted by mobile phones on Ammon’s horn and the dentate gyrus (DG) in the hippocampus and cerebellum of male Wistar albino rats. We also investigated the neuroprotective effects of the antioxidants Boswellia sacra (BS) and folic acid (FA) against exposure to EMF. Twenty-four adult male rats were randomly divided into four groups of six animals each, an EMF group, an EMF+FA exposure group (EFA), an EMF+BS exposure group (EBS) and a control group (Cont). The EMF, EFA and EBS groups were exposed to 900-MHz EMF...

Skeptical approaches concerning the effect of exposure to electromagnetic fields on brain hormones and enzyme activities
Publication date: Available online 14 September 2017 Source:Journal of Microscopy and Ultrastructure Author(s): Aymen A. Warille, Gamze Altun, Abdalla. A. Elamin, Arife Ahsen Kaplan, Hamza Mohamed, Kıymet Kübra Yurt, Abubaker El Elhaj This review discusses the effects of various frequencies of electromagnetic fields (EMF) on brain hormones and enzyme activity. In this context, the mechanism underlying the effects of EMF exposure on tissues generally and cellular pathway specifically has been discussed. The cell membrane plays important roles in mediating enzymatic activities as to response and reacts with extrac...

Exposure to 2100MHz Electromagnetic field radiations induces reactive oxygen species generation in Allium cepa roots
Publication date: Available online 8 September 2017 Source:Journal of Microscopy and Ultrastructure Author(s): Shikha Chandel, Shalinder Kaur, Harminder Pal Singh, Daizy Rani Batish, Ravinder Kumar Kohli During the last few decades there has been an enormous increase in the usage of cell phones as these are one of the most convenient gadgets and provide excellent mode of communication without evoking any hindrance to movement. However, these are significantly adding to the electromagnetic field radiations (EMF-r) in the environment and thus, are required to be analysed for their impacts on living beings. The present...

In vivo bioluminescence-based monitoring of liver metastases from colorectal cancer: an experimental model
In this study we aimed to develop a new in vivo bioluminescence-based tool to monitor and to quantify colon cancer (CC) liver metastasis development. HCT 116 cells were transducted with pLenti6/V5-DEST-fLuc for constitutive expression of firefly luciferase. Infection was monitored analyzing endogenous bioluminescence using the IVIS Lumina II In vivo Imaging System and a positive clone constitutively expressing luciferase (HCT 116-fLuc) was isolated. HCT 116-fLuc cells were left untreated or treated with 1μM GDC-0449, a Hedgehog pharmacological inhibitor. Moreover, 1×106 HCT 116-fLuc cells were implanted via intra-splenic...

Effects of electromagnetic fields exposure on the antioxidant defense system
Publication date: Available online 2 August 2017 Source:Journal of Microscopy and Ultrastructure Author(s): Elfide Gizem Kıvrak, Kıymet Kübra Yurt, Arife Ahsen Kaplan, Işınsu Alkan, Gamze Altun Technological devices have become essential components of daily life. However, their deleterious effects on the body, particularly on the nervous system, are well known. Electromagnetic fields (EMF) have various chemical effects, including causing deterioration in large molecules in cells and imbalance in ionic equilibrium. Despite being essential for life, oxygen molecules can lead to the generation of hazardous by-prod...

First insights into the ultrastructure of myosin and actin bands using Transmission Electron Microscopy in Gyrodactylus (Monogenea)
This study aims to describe the ultrastructure of coiled musculature fibres component of G. gasterostei and its role in this parasite transmission. The present work employs Transmission Electron Microscopy (TEM) to analyse Gyrodactylus gasterostei musculature, revealing the presence of myosin and actin bands in the underlying epithelium, typical arrangement of the skeletal muscle. This study unravels for the first time the existence of a coil muscle component in which seems to be responsible for the remarkable flexibility of the musculature of Gyrodactylus and the efficiency of its transmission method to reach a nearby fis...

Evaluation of the safety of conventional lighting replacement by artificial daylight
Conclusions These results suggest that long hour exposure to high illuminance visible electromagnetic radiations induced severe alterations in brain function and general health in mice partly mediated by damages to the neocortex-entorhinal cortex-hippocampus axis. These findings raise caution over long hour use of high illuminance artificial light. (Source: Journal of Microscopy and Ultrastructure)
