Effect of pigments of Pseudomonas aeruginosa on adhering and cytotoxicity of A549 cell line
...Show More Authors

Pseudomonas aeruginosa  gram-negative, bacilli and facultative aerobic, P. aeruginosa cause cystic fibrosis patients, wounds, burns, and immunodeficienct patients,  that have many virulence factors such as pyocyanin , cytotoxic ,biofilm formation  and motility, Eighty-eight isolates belonging to P. aeruginosa were collected including the 66 clinical isolates obtained from different hospitals in Baghdad and were from different sources and 22 environmental isolates from previous studies of soil near oil fields. Microscopical and cultural characteristics were studied and diagnosed using biochemical tests, VITEC device, their ability to adhere to non-living (Polystyrene), living cell line (A549) and cytotoxicity of bacterial filtrate by MTT method. The results displayed that all isolates belonged to P. aeruginosa. The pigment-forming (pe26 – pc36) isolates and (PE33 – PC31) non-pigment-forming isolates were selected. That all selected bacteria were able to adhere to the Polystyrene  and an epithelial carcinoma of lung (A549) was of more than 300 colony formation units in dilution (1:10) ,(1:1000), and   (1:10000). The toxicity of the P. aeruginosa filtrate (pc36) isolated from clinical sources and producing pigments was 15.7, 34.5, 44 % at a concentration of 40, 60, 80 % respectively, while the isolate (pc31) that was isolated from clinical sources and non-producing pigment was 28.1, 75.2, 80.9 % at the same concentrations. As for the isolate (pe26),isolated from environmental sources and forming the pigment, the inhibition rate was 38.5, 83.1, 48.8 % at concentrations of 40, 60, 80) % respectively, and the isolate (PE33) that was isolated from environmental sources was 42, 73.4, 74.1 % at concentrations of  40, 60, 80 % respectively. The study will be helpful in evaluating the effect of pigment formation in P. aeruginosa on adhesion.

The Study of Genetic Variations of GCG Gene and it's Relationship to Obese in Iraqi Population
...Show More Authors

The present study conducted on 120 obese males and 50 healthy males, their age ranged from 20-50 years. The patients were divided into 3 groups based on Body Mass Index (BMI) and Central Obesity (CO), it has noticed that there is a significant relation between both indexes. The DNA was isolated from the blood of patients and applies for PCR by using designed primers for exons 1 and 3 of GCG gene. The results showed that there are mutants in exon 1 at locus 9573 (G/C) for 30 patients and locus 9864 (C/-) for 10 patients with X2 = 12.30, also it has fund mutants in exon 3 at locus 5397 (A/G) for 28 patients and locus 5434 (G/A) for 8 patients with X2 = 11.11. These mutants have a high significant effect P≤ 0.001 to cause pathogenicity.

Using of Iron Oxide Nanoparticles and Application in the Removing of Heavy Metals from Sewage Water
...Show More Authors

This study investigated the applicability of iron oxide (Fe2O3) nanoparticles for the removal of cadmium metal from sewage water by using batch scale experiments. The iron oxide nanoparticles of 27.7nm were synthesized using a biological method and characterized by Atomic Force Microscope (AFM).  The Box-Wilson design was used to conduct experiments with three parameters such as pH (2-6), time of adsorption (6-120min) and adsorbent dosage (5-25mg/L). The best conditions occurred at pH: 5.5; contact time: 95.8 min; and iron oxide nanoparticle dosage: 20.77 mg/L for maximum cadmium removal of (96.9%).

Modification of Searle’s Speech Act of Promising in its Application to Selected Religious and Political Texts
...Show More Authors

This study presents certain modifications done to the conditions set by Searle
(1969: 57) concerning the speech act of promising in order to render them to selected
sayings of Prophet Muhammad (P.B.U.H.) and Jesus Christ (P.B.U.H.) and to
political texts. These modifications make the conditions of the speech act of
promising appropriate for sincere promises made by the Messengers of God since
they deliver their Messages of God but they are unable, as Messengers, to fulfill
God’s promises which they make as part of their Messages and by representatives of
States who deliver speeches on behalf of their Governments. These are the only two
situations where the speakers can make promises and do not fulfill these prom

Astudy and Analysis of Geomagnetic Field By using Model of International Geomagnetic Reference Field (IGRF- 2000)
...Show More Authors

The IGRF model is the empirical representation of the Earth magnetic field recommended for scientific use by the International Association of Geomagnetism and Aeronomy(IAGA).

Since  the  Geomagnetic   field   has   the  abi lity  to   change  the orientation of satellite, the strength of Geomagnetic field and its horizontal component have been studied.

This paper discusses the phenomenon of the Geomagnetic field intensity and its horizontal component at diferent altitudes and at certain latitudes, the geomagnetic field data is obtained by using IGRF2000 model at Baghdad (44.7 degree East longitude) .

Benign prostatic hyperplasia (BPH) is one of the most common disease and major cause of morbidity in elderly men which may lead to bladder outflow obstruction and lower urinary tract symptoms (LUTS). Although sex steroid hormones play fundamental roles in prostate growth, their clinical significance is not completely clear. In the present study we assessed whether serum hormones levels as markers of prostate disease. This study includes (40) patients with benign prostatic hypertrophy and (40) control group with age rang (41-79) and (42-71) years respectively. The following biochemical investigations have been studied: Testosterone, Estradiol (E2), and Prostatic Specific Antigen (PSA) levels using ELISA method which correlated with t
