...Show More Authors

12 membered Schiff base macrocyclic ligands, 6,7,14,15-tetra phenyl-1,2,3,4, 4a,8a, 9,10, 11,12, 12a,16a-dodecahydro dibenzo [b,h] [1,4,7,10] tetraazacyclododecine L1, and 14 membered Schiff base macrocyclic ligands, 6,8,15,17-tetramethyl-1,2,3,4, 4a,7,9a, 10,11,12,13,13a,16,18a-tetra decahydro dibenzo[b,i] [1, 4,8,11] cyclotetradecine tetraaza L2, 7,16-bis(2,4- dichloro benz ylidene)-6,8,15,17-tetra methyl-1,2,3,4, 4a,7,9a, 10, 11,12, 13, 13a,16,18a-tetra deca hydro dibenzo [b,i] [1,4,8,11] tetra azacyclo tetra decine L3 and 6,8,15, 17-tetramethyl-1,2,3, 4,4a,9a,10, 11,12,13,13a,18a-dodecahydro dibenzo [b,i] [1,4,8, 11] tetraazacyclo tetradecine (7,16-diylidene) bis(methanylyli dene) bis (N,N-dimethylaniline) L4 were synthesized by condensation reaction between diketone and aliphatic diamines. The metal complexes of the types, [ML1Cl2], [ML2Cl2], [ML3Cl2] and [ML4Cl2] [M= Co(II), Ni(II), Cu(II), Mn(II), Hg(II), and Fe(II)] were prepared by interaction of ligands, L1, L2, L3 and L4 with metal(II) ions. The ligands and their complexes were characterized by elemental analysis, magnetic susceptibility, conductivity measurements and IR, 1H and 13C NMR, UV–Vis spectral studies. The thermal stability of the complexes was also studied by TGA analyses. These studies show that all the complexes have octahedral arrangement around the metal ions. We used CB-Dock, a novel blind docking technique that aims to improve docking precision. With the aid of the cutting-edge docking program Autodock Vina, software online, molecular docking studies were used to evaluate the biological significance of the synthesized ligands and identify the probable and efficient binding mechanisms between the various ligands and the active site of the receptor protein. Affinity binding of both Ligand L3 and L4 to Penicillin binding protein 2x (chain B) with PDB 1PYY were much better than to Penicillin binding protein 2B (chain A) with PDB 1WAE due to the presence of hydrogen and halogen bonds. Therefore, they can be more recommended for drug design study to inhibit bacterial growth due their bioavailability. The biological activities of all compounds were evaluated like in-vitro antioxidant activity or percentage free radical scavenging effect via DPPH method against standard ascorbic acid and in vitro anticancer activity via MTT assay against colon cancer cell lines. Results of the biological activities showed that complex CuL3Cl2 exhibited the highest anti-cancer activity against colon cancer cell line i.e. 70.72±6.3 μg/ml among other copper complexes whereas compound CuL3Cl2 showed best antioxidant activity against ascorbic acid i.e. 75.07±1.96 μg/ml. While the biological activities showed that complex CuL4Cl2 exhibited the highest anti-cancer activity against colon cancer cell line i.e. 42.05±7.4 μg/ml among other copper complexes whereas compound CuL4Cl2 showed best antioxidant activity against ascorbic acid i.e. 65.47±1.37 μg/ml.

Objectivity of the Liaison in the Iraqi Media Institutions (Al Mada, Azzaman, Al-Sumaria, Aletejah Instituations & Satalite Channels as a Model)
...Show More Authors

Objectivity is the common denominator between the qualities and elements of a news story that is described as the mother of journalistic arts. When there is doubt about the authenticity of the information contained in the press, whether readable, audible or visual, it means that there is an imbalance in objectivity. When, furthermore, there is an incorrect and intentional use of words in order to influence readers, it means to move away from objectivity as a necessary element in the success of the media institution; and the success of its editorial material.

But the objective interpretation may take several dimensions to the liaison. For the purpose of grasping the interpretation of objectivity among those liaisons working in the

PDF Photodynamic effect of Rose Bengal activated by low-level laser light on S. aureus : Qusay K. Abbas*, Layla M. Hassan
...Show More Authors

Abstract: Background: Staphylococcus aureus is Gram-positive bacteria that lives as a normal flora in living organisms but can be pathogenic to humans. Although a relatively unspectacular, nonmotile coccoid bacterium, S. aureus is a dangerous human pathogen in both community-acquired and nosocomial infections. Due to the increasing emergence of new strains of this antibiotic-resistant bacteria, it has become essential to approach different methods to control this pathogen. One of these methods is the antimicrobial photodynamic inactivation process using a low-level laser, in this paper, the Photodynamic effects of Rose Bengal and LLLL on the virulence factors of S.aureus were evaluated.

Optimization of Culture Conditions to Produce Phytase from <i>Aspergillus tubingensis SKA</i>
...Show More Authors

The effects of nutrients and physical conditions on phytase production were investigated with a recently isolated strain of Aspergillus tubingensis SKA under solid state fermentation on wheat bran. The nutrient factors investigated included carbon source, nitrogen source, phosphate source and concentration, metal ions (salts) and the physical parameters investigated included inoculum size, pH, temperature and fermentation duration. Our investigations revealed that optimal productivity of phytase was achieved using wheat bran supplemented with: 1.5% glucose. 0.5% (NH4)2SO4, 0.1% sodium phytate. Additionally, optimal physical conditions were 1 × 105 spore/g substrate, initial pH of 5.0, temperature of fermentation 30˚C and fermentation dura

The Effect of Increasing Rehabilitation Program Using Electric Stimulation On Rehabilitating Knee Joint Working Muscles Due to ACL Tear In Athletes
...Show More Authors

The research aimed at designing a rehabilitation program using electric stimulation for rehabilitating knee joint working muscles as a result of ACL tear using an apparatus developed by the researchers that stimulate the muscle vibration and work as well as the ability to rehabilitate the join in shorter periods. In addition to that, it aimed at identifying the effect of this program on rehabilitating the knee joint working muscles. The researchers used the experimental method on Baghdad clubs’ players who suffer from complete knee joint ACL tear aged (19 – 24) years old. The results showed that the training program developed the working muscles significantly achieving normal levels of activity.

...Show More Authors

The largest use of x-ray in medical by dentists, employers or persons that needed by patients with specific conditions, lead to higher exposure of x-ray that may cause many diseases. In the present work radiography films have been used in evaluating the efficiency of using unsaturated polyester polymer reinforced with lead oxide (PbO) as shield material for medical x-ray devices, many parameters studied like concentration and thickness that they are increasing the attenuation of x-ray in them. The results show that the attenuation of X-ray increasing with concentration of reinforced material and with thickness, and the optical density decreases with increasing concentration from 0% to 50%, we chose 30% as suitable concentration to increase

In wide range of chemical, petrochemical and energy processes, it is not possible to manage without slurry bubble column reactors. In this investigation, time average local gas holdup was recorded for three different height to diameter (H/D) ratios 3, 4 and 5 in 18" diameter slurry bubble column. Air-water-glass beads system was used with superficial velocity up to 0.24 m/s. the gas holdup was measured using 4-tips optical fiber probe technique. The results show that the axial gas holdup increases almost linearly with the superficial gas velocity in 0.08 m/s and levels off with a further increase of velocity. A comparison of the present data with those reported for other slurry bubble column having diameters larger than
