INTERACTION PATTERN OF FULLERENE FAMILY WITH DIFFERENT FORMS OF DNA[ ]


Fullerenes have attracted considerable attention due to their unique chemical structure and potential applications. In this study fullerenes (C20 to C180) were interacted with different forms of DNA i.e. A, B and Z-forms. And no such change in the binding score was observed with the change in the sequence of DNA. In fact, binding score increases with the increase in the molecular weight of the fullerene while interacting with A & B-form of DNA but Z-form of DNA shows no regular pattern of binding. Number of interacting base pairs increases as the molecular size of fullerene increases. And the groove binding depends on the form of DNA, fullerene and fullerene family binds in major groove of A-DNA while binds in both major and minor grooves in B and Z-form of DNA. This study reveals that binding pattern of fullerene family with DNA, which can disrupt its structure and may leads to several biological errors.

Synthesis, Biological Activity, Molecular Docking and Structural Studies of N-(O-Fluor phenyl)-4,6-Dimethyl-2-Pyridone-3-Nitrile[ ]


The title compound crystallizes in space group, P21/c with unit cell parameters, a=7.926(5), b=11.156(3), c=14.261(3) Å, ß = 102.01(1)°,V = 1233.4(9) Å3 containing four asymmetric molecules. The molecules are packed in the crystal lattice with bifurcated hydrogen bonding of the type C-H---O. Oxygen atom O(1) is involved in the bifurcated hydrogen bonding with bridge distances 3.511(2) Å and 3.466(2) Å, respectively. Fluorine F(1) of the phenyl ring does not involve in either intra- or inter-hydrogen bonding. The dihedral angle between the phenyl group and pyridone ring is 87.7(1)° indicating that pyridonyl group is perpendicular to the phenyl group making the way for its maximum interaction through weak hydrogen bondings. Molecular docking study done on this compound with Phospholipase (PLA2) indicates that there are hydrogen bond and hydrophobic interactions at the active sites on the PLA2. The molecule is stabilized through these interactions with distances varying from 2.5 to 4 Å and hence it is a good candidate for the study of inhibition activity of the enzyme based on its experimental evidences. Also a study of in-vitro biological activity carried out indicates that the compound has antioxidant and hydrogen-peroxide-radical scavenging properties and more potent than ascorbic acid taken as standard.

Enhancement the Strength of Conventional Concrete by using Fly ash and Nylon Fiber[ ]


Fiber can be defined as a small piece of reinforcing material possessing certain dimensional characteristics. The most important parameter describing a fibre is its Aspect ratio “Aspect Ratio” is the length of fibre divided by an equivalent diameter of the fibre. The properties of fibre reinforced concrete are very much affected by the type of fibre. Fibres are secondary reinforced material and acts as crack arrester. Prevention of propagation of cracks originating from internal flaws can result in improvements in static and dynamic properties of matrix.

Isolation and detection of pseudomonas aeruginosa from post-surgery operatives wound in Babylon provine hospital/ Iraq[ ]


A study was carried out to assess isolation and detection ofPseudomonas aeruginosa from post-surgery operatives wounds in Babylon Province Hospitals (General Al-Hashemeyah hospital and Al-Shomali General Hospital). Methods: 100 specimens were taken from post operative surgery wounds. The identity of isolates was confirmed by staining method (Gram stain) , culturing (Nutrient,Macconkey,Blood and TSA agars), biochemical tests (Catalase , Oxidase, Citrate, Methyl red, Voges-Proskauer,Indole and Lactose fermentation) and Antibiogramtests. Results: from 100 samples, 24 isolates of Pseudomonas aeruginosawere collected. The biochemical activities were positive in Catalase , Oxidase and Citrate and negative in Methyl red, Voges-Proskauer,Indole and Lactose fermentationwere fixed as features of it. Among the variety of antibiotics tested, the highests resistance were found with Ampicillin (75%) and Oxytetracycline (70.8%) followed by Amoxicillin (66.6%) and Tetracycline (62.5%), On the other hand, both the isolates were intermediately sensitive to Gentamicin (62.5%), Kanamycin (58.3%) and Erythromycin (54.1%).while the isolates were highly sensitive to Chlo-ramphenicol (70%) and Ciprofloxacin (66.6%). Conclusion: P. aeruginosa one of the most important pathogenic bacteria that infect the post-operative wounds.and in some cases even with antibiotic therapy. All the human ages may undergo the infection with P. aeruginosa with different immunity conditions.Reccurent uses of the same antibiotics may be lead to bacterial resistance because the multi-antibiotics resistance mechanism of P. aeruginosa.Hyagenic managment include Sterilization and Disinfectant methods which established in some hospitals are not enough to prevent the infection of pathogenic bacterial as nasocomial infections.

A Comparative Study of Image Encryption Methods Using Coupled Map and Non-Linear Chaotic Algorithm[ ]


With the rapid development of computer network and multimedia technology, the security of digital image information has become a major concern. For image data with privacy and national security should be transmitted in a secret way, image encryption technology has drawn more and more attention. In this project two digital image encryption methods based on the chaotic systems are used for the high level security and the key space, Non-linear Chaotic Algorithm (NCA) and a novel algorithm based on mixture of chaotic maps or coupled map, NCA uses the power functions and tangent functions instead of linear function to increase the key space and high level security. In novel algorithm based on mixture of chaotic maps or coupled map, a typical coupled map was mixed with a one-dimensional chaotic map and used for high degree security image encryption while its speed is acceptable, and also it has large key space than the NCA map. By experimental results the mixture of chaotic system or coupled map is robust than the NCA map.
