Extraction and Partial Purification of Lipopolysaccharide from Clinical Proteus mirabilis Isolate and Compared with Standard Bacteria
...Show More Authors

Ninety five samples were collected from different samples (urine, ear and wounds swaps), from hospitals in Baghdad city. The results of cultural, microscopic , biochemical tests indicated that in urine samples E.coli have high occurrence frequency 19 (47.5%) followed by Proteus mirabilis 18(45%) and Klebsiella species 1 (2.5%), while in wounds samples each of Pseudomonas spp. and Proteus mirabilis 10 (25%) , then followed by E.coli with 5 (12.5%) and Klebsiella species 3 (7.5%). Ear swaps samples revealed that Pseudomonas aeruginosa 7 (46%) was the major bacterium followed by Proteus mirabilis 4(26.6).Sensitivity test against eleven antimicrobial agents was done for all of the Proteus mirabilis isolates (32 isolates). The results displayed that most of the isolates were resistant to Methicillin (96.8%), and Rifampin (93.7%) followed by trimethoprim–sulfamethoxazole (71.8%), chloramphenicol (62.5%), and cefazoline (59.3%). while the most effective antimicrobial agents against P. mirabilis were Imipenem (96.9%), Azetronam (81.3%), Azithromycin (71.9%) ,Ciprofloxacin (69%).Whereas a moderate effect appeared against both gentamycin and tobramycin in a percentage of (53.2 and 62.5) % respectively. More resistant isolate was selected, and lipopolysaccharide was extracted by hot EDTA method and the yield was (051) mg LPS from (22)g dry weight cell of pathogenic P.mirabilis and (95) mg as LPS from (16) g dry weight cell of standard bacteria were obtained. After partial purification ,chemical analysis of crud and partial purified LPS showed that the carbohydrate percentages were (35 , 44.3) % and (49 , 62)%, while the protein percentage (0.98 ,0.1) % and ( 1.3 ,0.1)% for the standard and isolated bacteria respectively ,whereas both extract appeared free from nucleic acid . Molecular weight of LPS was estimated and it was equivalent to (63095 and 70794) Dalton for the standard bacteria and pathogenic one respectively.

Treatment of Waste Paper Using Ultrasound and Sodium Hydroxide for Bioethanol Production
...Show More Authors

Bioethanol produced from lignocellulose feedstock is a renewable substitute to declining fossil fuels. Pretreatment using ultrasound assisted alkaline was investigated to enhance the enzyme digestibility of waste paper. The pretreatment was conducted over a wide range of conditions including waste paper concentrations of 1-5%, reaction time of 10-30 min and temperatures of 30-70°C. The optimum conditions were 4 % substrate loading with 25 min treatment time at 60°C where maximum reducing sugar obtained was 1.89 g/L. Hydrolysis process was conducted with a crude cellulolytic enzymes produced by Cellulomonas uda (PTCC 1259).The maximum amount of sugar released and hydrolysis efficiency were 20.92 g/L and 78.4 %, respectively. Sugars

Comparison of ABGAR Score among Gestational, Pregestational Diabetes and Normal Pregnant Women
...Show More Authors

Background: The Apgar score is calculated based on the five features: heart rate, reflexes, color, muscle tone, and respiratory effort. Each element is scored from 0 to 2, with a total probable score of 10 at 1 minute and 5 minute. Aim: To study the influence of gestational diabetes mellitus (GDM) and diabetes mellitus on APGAR score in neonate. Materials and methods: The samples were studied from Department of Obstetrics and Gynaecology in Al-Imamain Al-Kadhimiyain (AS) Medical city, Baghdad Teaching Hospital and Al-Karkh Maternity Hospital in the period between 1 December 2016 and 1 may 2017, after obtaining the approval from Iraqi Ministry of Health. A total of 102 neonates were included in this study which includes 34 neonates of mother

Achieving the Benefits and Requirements of Integrated Project Delivery Method Using BIM
...Show More Authors
Abstract<p>Through the last decade, Integrated Project Delivery (IPD) methodology considers one of the new contractual relations that are also on the way to further integrate the process of combining design and instruction. On the other hand, Building Information Modeling (BIM) made significant advancements in coordinating the planning and construction processes. It is being used more often in conjunction with traditional delivery methods. In this paper, the researcher will present the achievement of IPD methodology by using BIM through applying on the design of the financial commission building in Mayssan Oil Company in Iraq. The building has not been constructed yet and it was designed by usin</p> ... Show More

Antibacterial activity of thuja orientalis and green tea in pseudomonas areogenosa infection
...Show More Authors

Seven isolates were identified as Pseduomonas aeruginosa from clinical samples. Antibiotic sensitivity test were done to determine their sensitivity to number of antibiotics, the results illustrated all that isolates were resistant to most used antibiotics. The ability of Pseduomonas isolates to produce haemolysin, protease and pyocyanin were detected in this study, all isolates had the ability to produce pyocyanin pigment, hemolysis and protease. The antimicrobial activity of the ethanolic extracts of Thuja orientalis and green tea against P.aeruginosa were investigated. The results showed that both these plant extracts have inhibitory effect against Pseduomonas isolates and it was shown that ethanolic extract of green tea was more efficie

...Show More Authors

Hyperpigmentation is the increase in the natural color of the skin. The purpose of this study is to evaluate the efficacy and safety of Q-Switched Nd:YAG (1064 & 532 nm) Laser in treatment of skin hyper pigmentation. This study was done in the research clinic of Institute of laser for postgraduate Studies/University of Baghdad from October 2008 to the end of January 2009. After clinical assessment of skin hyperpigmentation color, twenty six patients were divided according to their lesions. Eight Patients with freckles, seven patients with melasma, four patients with tattoo. Cases with tattoo, were subdivided into amateur tattoos two, professional tattoos one, and one traumatic tattoo.

The Effects of the research and technology development contract -A comparative study-
...Show More Authors

Researching the effects of the research and technological development contract, determining its extent and demarcating the boundaries of the obligations imposed in it, is the cornerstone of economic growth and development, because defining these obligations removes the ambiguity and conflict between interests, by stating the rights owed to each party and even trying to reconcile them, or impose protection by specifying guarantees that are compatible with the essence of the R&D contract, For the purpose of studying the subject thoroughly, we will divide this research into two sections. The first is devoted to identifying the parties to the research and technological development contract. As for the other topic, we will explain the obligation
