A Study on the Prevalence of Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus (MRSA) on Mobile Phone Devices
Abstract: Mobile phone devices are indispensable accessories in social life used for communication. The users normally do not clean their cell phones which, therefore, serve as a reservoir of potential pathogenic bacteria. The devices are the vehicles of pathogen transmission in both health and non-healthcare settings. The presence of multiple drug-resistant strains of Staphylococcus aureus is very important as it can cause both hospital- and community-acquired infections. The present study is …

Frequency and Effect of CCR5 Alleles on HIV-1 Disease Progression among Untreated Seropositive Individuals Visiting Gondar University Teaching Hospital
Abstract: Abstract:The natural history of HIV-1 infection varies considerably from one individual to another, with some individuals progressing to AIDS rapidly after primary infection, while others remain clinically asymptomatic with no evidence of immune dysfunction. Recent studies have shown that reasons for progression and non-progression are multi-factorial and may involve genetic, virological and immunological factors that influence HIV disease progression in various ways. Chemokine receptors act as important co-receptors mediating the …

Simple Hydrothermal Synthesis and Morphological Study of Magnetic Nanoparticles
Abstract: Magnetite (Fe3O4) nanoparticles were synthesized using FeCl3•6H2O or FeCl2•4H2O with 5 or 8 mmol concentration and 3 or 5 h incubation time with the constant pH (7.5) by simple hydrothermal decomposition and then transferred them into maghemite (γ-Fe2O3) and hematite (α-Fe2O3). Precisely, the objectives of the study were to evaluate the influences of salt type, its concentration and incubation time on the morphology of the as-synthesized magnetic nanoparticles. Synthesized nanoparticles …

Detrimental Effect of Mobile Phone Radiation on Living Organisms: An Update Review
Abstract: Mobile phone has raised the risk of the tissue-level damage for all living organisms not only for human and animals but plants as well. Numerous studies have documented various biological effects of EMR including changes in cell proliferation, enzyme activity, gene expression, cell-membrane permeability and ion homeostasis as well as oxidative stress and heat-shock response. A modulated field at 900 MHz strongly inhibited the growth of and, to some extent, …

Abstract: We have studied the drain characteristics in single-heterojunction AlGaN/GaN high electron mobility transistors (HEMTs) using the SILVACO-ATLAS software tool. The drain characteristics are studied with respect to five types of simulated structures. In each type of structures, the gate length and thickness of AlGaN nano-layer are different with respect to other types. Effects of drain voltage and gate voltage on drain current are studied by the simulated structures. Also, the …
