Isolation and Characterization of Bacteriophage Against Methicillin Resistant Staphylococcus aureus[Full-Text ] Mariem N. Mohammed-Ali and Nidham M. JamalludeenMethicillin resistant Staphylococcus aureus (MRSA) is a major human pathogen responsible for several life threatening conditions. MRSA have the ability to acquire resistance to several antimicrobial agents and phage therapy is one potential option to treat this pathogen. The aim of the study was to isolate and characterize bacteriophages effective against a wide range of methicillin-resistant Staphylococcus aureus (MRSA). A mixture of ten MRSA isolates was used for the isolation of phage from wastewater treatment plants. Three phages were selected for further characterization. All three phages belong to the Siphoviridae family and have long non-contractile flexible tails. The three phages showed a wide host range against S. aureus. Phages ɸSA1 and ɸSA2 were resistant to a pH range from 4-10 while ɸSA3 has a pH range from 3-11. DNA from all three phages were resistant to digestion by endonuclease enzymes such as EcoRI and AccI. There was a high degree of mosaicism among the three virulent phages and with their ancestor phages of Siphoviridae due to their non-uniform access to the common genetic pool by horizontal gene transfer and recombination. Since some of the staphylococcal toxins are phage encoded, the presence of genes for such toxins was tested by performing polymerase chain reaction and all three phages lacked genes for any of the staphylococcal toxins, including staphylococcal enterotoxins (sea, seb, sec and see), exfoliating toxins (eta and etb) and the toxic shock syndrome toxin (tst), therefore these bacteriophage are suitable candidates for future use in phage therapy against MRSA.

Cancer Bio-Informatics New Future of Cancer Therapy[Full-Text ] Ayan Chatterjee, Dr. Uttam Kumar RoyWe all are very familiar with the name "cancer" which claims nearly 7 million lives each year worldwide. To fight against cancer different type of treatment approaches are taken and as time passes sophisticated research proposals are made. Bioinformatics is also not an exception. DNA sequencing, microarray expression profiling and genomic sequence analysis are different research fields under bioinformatics. Currently our adopted medical treatments are based on chemotherapy that are not target specific and maximizes the side effects. This article reviews and discusses recent advances in the treatment of cancer with the help of bioInformatics as many challenges yet to overcome in reduced cost and time. Traditional chemotherapy/radiation therapies are costly. It is better to have molecularly targeted therapies like ligand targeted therapy which are more targets limited, produces less toxicity and can overcome many drug resistance challenges. It is a challenge to develop accurate tools for delivering the right treatment to the right patient based on biological characterization of each patient's tumor.

Text Based Steganography - A Theoritical Proposal of Text Based Hiding Strategy[Full-Text ] Ayan Chatterjee, Gourab Dolui, Dr. Uttam Kumar RoySteganography is a useful tool of hiding information in ways that prevent the detection of hidden messages. It serves better than cryptography which only hides the content of the message not the existence of the message. The output of steganography operation is not actually visible but in cryptography the output is scrambled so that it can draw attention. In Steganography, Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. It is a process of combining secret information with the carrier medium gives the hidden message. The hidden information is difficult to detect without retrival. This paper will look at a new proposal on text based information hiding technique (encoding or encryption) and steganolysis (decoding or decryption) technique on top of the existing text based methods. Text based steganography with digital files is not used very often since text files have a very small amount of redundant data. Using this technique we can hide more binary information with minimal number of alphabets. This method also provides a security on secret binary information.

Assessment of a gradient thermostat unit: Implications to field alterations at a 11.7 Tesla preclinical system[Full-Text ] Irati Markuerkiaga, Sandra Plaza-GarcÃa, Daniel Padro, Torsten ReeseModern high field preclinical MRI systems are built compact, with gradient coils that fit tightly in the magnet bore. Thus, heat generated during operation can be transferred directly from the gradient coil surface to the passive shims causing undesired field fluctuations that may affect data quality. The performance of a commercial thermostat unit that is designed to pre-heat the passive shims to limit these fluctuations is described for a preclinical 11.7 Tesla system. The main magnetic field is affected by changes in the cooling water of the gradient alone, indicating that a compact system design allows an efficient heat transfer from the gradient surface to the passive shims. Similar results are obtained when the gradients are pulsed. The thermostat unit that preheats the passive shims to 42.5 Celsius reduces the magnitude of the field variations by 90%. The in vivo experiments confirmed that the pre-heating of the passive shims is required, even for standard robust sequences.The thermostat unit reduces the field variation to a range that is acceptable for routine applications. However, any study that analyses spatio-temporal signal changes requires knowledge of the apparent irregular field variations created by the feed-back controlled thermostat unit.

Optical and Solid State Properties of Manganese Sulfide Thin Films Deposited Using Chemical Bath Method[Full-Text ] R. A. Daniel-Umeri and K. EmumejayeManganese Sulfide (MnS) thin films were successfully deposited on glass substrate at room temperature via a simple, cheap technique; chemical bath method. The baths contained manganese sulphate (MnSO4. H2O) of different concentrations (0.1M, 0.2M 0.3M), thiourea [SC (NH2)2] and Ammonia (NH3) solution which acted as the complexing agent. The effects of the bath concentration on the optical and solid state properties of the films were investigated. The as-deposited films was characterized by the 752N England UV-VIS Spectrophotometer in the wavelength range of 200-1000nm. The results showed that films deposited at 0.1M was found to posses high values of absorbance, absorption coefficient, refractive index , extinction coefficient and optical conductivity. Transmittance and reflectance values were low. Films deposited at 0.2M and 0.4M, showed an inverse of these properties. The band gap energy of the material was found to increase as concentration increases. It was found to be in the range of 2.4eV - 2.8eV. These properties make MnS thin film suitable as Spectral Selective Surfaces for Solar Energy Application.

A Quasi- Empirical Investigation of the Relationship between Real Financial Events and Profit Management in Companies Accepted by New York Stock Exchange[Full-Text ] Sadaf Yahyaei, Hesam JabbariMany current researches in the field of profit management are focused on discovering unusual accruals. Profit management may be performed by accruals, real financial events or both of them. Till now, little works have been performed to identify whether unusual accruals are due to manipulation of accruals without the effect of cash flows or due to manipulation of real events which are effective on both cash flows and arrears. The current study aims to evaluate manipulation of real financial events through focus on variables such as cash flows induced by operation, optional costs, variation in inventory and production costs. Accruals are selected as an appropriate alternative for measuring the profit management. The results show that there is a meaningful relationship between operation cash and variation in inventory and profit management in companies accepted by New York Stock Exchange.

Evaluation of the accumulation of some heavy metals in the red beetroot (Beta vulgaris L.) grown on two different soils and irrigated by wastewater from the SETP Bouznika (Morocco)[Full-Text ] D. Ez-zarhouny, E.M. Hbaiz, M. Lebkiri, S. Elanza, A. Lebkiri, E.H.Rifi, N. HabbadiThe present work aims at evaluating the metal contamination of the red beet (Beta vulgaris L.), irrigated by wastewater treated by wheat straw of Bouznika STEP (Morocco) and cultured on two different soils, one of Maâmora and the other of Bouznika. The results of the ICP-AES analysis showed that the increasing intake of raw sewage causes a significant accumulation of metals in different organs of the plant. However, irrigation with treated wastewater (EUT) allowed a reduction of the concentrations of various metals especially those of lead, nickel and chromium. So, with 100% of treated wastewater, the concentration of lead rose from 5,88ppm to 3,1ppm in the soil of Bouznika.The statistical study by principal component analysis (PCA) revealed the existence of correlation between wastewater intake and the metallic levels in the plant’s organs.

IMPLEMENTATION OF MODULAR EXPONENTIATION USING MONTGOMERY ALGORITHMS[Full-Text ] Manish Bansal, Amit Kumar, Aakanksha Devrari, Abhinav BhatSeveral algorithms for Public Key Cryptography (PKC), such as RSA, Diffie-Hellman, and Elliptic Curve Cryptography are used for secure communications. These algorithms require modular exponentiation as their basic operation. Modular exponentiation implies repeated modular multiplication which is computationally very costly as the large operands are used. Therefore computation time is very large. This computation time can be reduced by Montgomery multiplication algorithm. Montgomery multiplication algorithm involves three basic phases 1. Conversion of operands from integer domain to Montgomery domain. 2. Multiplication of operands. 3. Conversion of operands back from Montgomery domain to integer domain. A architecture designed to implement Montgomery Modular exponentiation using right to left exponentiation approach, which allows the parallel execution of modular operations “square and multiplications”. The implementation of Montgomery modular exponentiation is achieved on Spartan3E, virtex4 and virtex6 series of FPGAs for 4, 8, 16 and 32 bits respectively
