Magnetic resonance imaging (MRI) is a non-invasive medical test that uses intense magnetic fields to make images of the inside of the body. Generally, the magnetic resonance (MR) image quality depends on the effect of MRI parameters on the signal-to-noise ratio (SNR) which is often calculated using samples taken from reconstructed image that will enhance image quality. Ogura, Miyai, Maeda, Fkutake and Kikumoto (2003) state that the SNR of a magnetic resonance image is common measure of imager...
A telemedicine system using communication and information technology to deliver medical signals such as ECG, EEG for long distance medical services has become reality. In either the urgent treatment or ordinary healthcare, it is necessary to compress these signals for the efficient use of bandwidth. This paper discusses a quality on demand compression of EEG signals using neural network predictors for telemedicine applications. The aim of this work is to obtain a greater compression gains at a...
Introduction One of the unsolved mysteries of plant evolutionary biology is the functional significance of the two thousand-fold variation in the genome size of individual species, particularly among the angiosperms. Genome size ranges from around 108 Mb for Fragaria viridis (Bennett & Leitch, 2005) to over 120,000 Mb in some Liliaceae members (Leitch, Beaulieu, Cheung, Hanson, Lysak, & Fay, 2007). This variation is largely attributable to different proportions of non-coding...
GLOBAL THREAT OF INFLUENZA VIRUS OUT BREAK AND IMPORTANCE OF ITS PREPAREDNESS1. History of influenza viruses In the past, avian influenza viruses were believed to be replicated poorly in humans and other mammals, as there was no convincing evidence of non avian infections by avian influenza virus. However, since 1997 there have been repeated cases of human infection by avian H9N2 and H5N1 influenza viruses in Southern China, Thailand Vietnam and Indonesia. Recently H1N1 (swine flu) is added to...
Food allergens play a pivotal role in the manifestation of atopic disorders like asthma, rhinitis, eczema and other skin reactions among children. IgE level and cytokine level have an essential role in allergy and asthma. There are few studies based on the role of Th17 in food allergic children. Th17 cells play a key role in regulation of inflammatory diseases. Objective- The present research aims at studying the immune response of atopic children having genetic predisposition to allergy by...
Many different mechanisms may contribute to oxidative processes in the body, for example Fenton reactions, where transition metal ions are involved in the generation of ROS which can cause damage to various body structures such as lipids, proteins and DNA. Therefore, a variety of different antioxidant assays were studied to determine by which mechanism(s) each herbal formulation exerts their antioxidant activity. Compounds such as, phenols and flavonoids are considered to be major contributors...
This paper presents an overview of techniques for characterizing inhomogeneities in various forms of organic surface films including organic coatings and anti-corrosion oil and inhibitor films. Particular focus is on technological innovations that have been made over the past two decades for gaining better understanding of inhomogeneities in surface films and their effects on underfilm localized corrosion. These include scanning probe techniques such as the scanning Kelvin probe, scanning...
As we walk through the history of human being. We can see that in the Paleolithic era, our ancestors have used stone as a tool for various purposes, which was the beginning of discoveries and invention. The history of technological development from the use of stone, bone and fire to the recent claim by Craig Venture that they have created first synthetic bacterial cell (Gibson et al., 2010), is awesome. One of the greatest inventions of the present time in the field of biotechnology is...
Parenchyma cells are one of the three main types of plant cells. They are the general and multifunctional cells that make up much of a plant (Dengler, Nancy). Within the Parenchyma genre, there are several different varieties of the cell. Some Parenchyma cells are called Chlorenchyma cells ("Parenchyma Cells and Tissues"). Chlorenchyma cells are filled with chloroplasts. Other variations of the Parenchyma cell are filled with air, giving the leaves of the plants they make up...
Arsenic is a well-known toxic metal and is present mainly as oxyanion compounds in groundwater. The World Health Organizations current provisional guideline for arsenic in drinking water is 10 µg/L, but all developing countries affected with contaminated groundwater are still struggling to keep up with the previous WHO guideline value of 50 µg/L (2). Arsenic compounds are widespread contaminants in the environment. Because of arsenic toxicity and induced carcinogenity (Eblin et al., 2006;...
