Role of Extracted Genomic DNA on Biofilm Formation by Pseudomonas aeruginosa and Klebsiella pneumoniae in vitro
...Show More Authors

   Bacteria form complex and highly elaborate surface adherent communities known as biofilms.Biofilm have been shown to be associated with several human diseases ,and to colonize a wide variety of medical devices . The current study focuses on contribution of extracted genomic   DNA in  biofilm formation by   P. aeruginosa and  K. pneumoniae isolates   .The percentages of Pseudomonas aeruginosa recovery from drinking water  in this study were  10%(20 positive P. aeruginosa  samples ) and K. pneumonia.,  7%(14 positive K. pneumonia samples).The results showed that all P.aeruginosa and K. pneumoniae isolates (100%) were slime producer but in different degrees by forming  of black colonies on congored agar: very  black colonies , black colonies  and red colonies  .Results  indicated that addition of extracted genomic   DNA to microtitre-plate cultures stimulate biofilm formation(either endogenous or exogenous DNA).

Simultaneous influences of hematocrit in the erythrocyte medium on erythrocyte aggregation and sedimentation: a kinetic study by a laser scattering technique
...Show More Authors

The erythrocyte aggregation is an important physiological phenomenon in the circulation of blood. It is a basic characteristic of normal blood that plays a major role in the cardiovascular system, especially in the microcirculation. This study explained the kinetics of single cells rouleaux formation one- dimensional aggregate and three- dimensional aggregate, during simultaneous, and the effect of hematocrit on the process of aggregation and sedimentation. The present study was done on forty one healthy subjects. Laser light is passed through a well mixed sample of blood and the forward scattered light intensities recorded continuously. The samples were prepared with different hematocrit, (10%, 15%, 20%, and 25%). Increasing

Study influence of thickness and electrode mater on some electrical properties for ZnSe thin films prepared by thermal evaporation in vacuum
...Show More Authors

Thin films of Zinc Selenide ZnSe have been prepared by using thermal evaporation in vacuum technique (10-5Torr) with thickness (1000, 2700, 4000) A0 and change electrode material and deposited on glass substrates with temperature (373K) and study some electrical properties at this temperature . The graphs shows linear relation between current and voltage and the results have shown increases in the value of current and electrical conductivity with increase thickness and change electrode material from Aluminum to Copper

ROLE OF CORPORATE GOVERNANCE IN PROTECTING INVESTORS' RIGHTS / ANALYTICAL STUDY IN THE IRAQI STOCK EXCHANGE: ROLE OF CORPORATE GOVERNANCE IN PROTECTING INVESTORS' RIGHTS / ANALYTICAL STUDY IN THE IRAQI STOCK EXCHANGE
...Show More Authors

The current research focuses on a major problem: the weak role of disclosing corporate information in the application of laws, regulations and instructions related to the application of corporate governance principles weakens the ability to protect the rights of shareholders and investors in companies listed on the Iraqi Stock Exchange and the study aims to study and analyze the role of disclosure and transparency in achieving the necessary protection to ensure the rights of shareholders. The study was applied to a sample of (42) analysis samples representing (84%) of the total questionnaires distributed to investors and shareholders in all listed companies in the Iraqi Stock Exchange. The results confirm the shareholder's right to obtai

in vitro evaluation of inhibitory activity of enteric Bifidobacterium isolates against Shiga toxin producing E.coli (STEC)O157:H7
...Show More Authors

Six Bifidobacterium isolates, isolated from breast – feed infant faces on reduced de Man Rogosa and Sharp medium (MRS - C). Isolates identified to species level on the basis of : microscopical properties, biochemical tests, fructose-6-phosphate phosphoketolase enzyme(F6PPK) activity and carbohydrates fermentation profile. Results showed that B. adolescentis was the predominant species (B4,B5and B6),the other species were B. breve(B3),B. longum (B1), B. dentium(B2).
Strains were screened for their inhibitory effects against pathogenic bacteria shiga toxin producing E.coli(STEC)O157:H7 using agar – well diffusion method.B3 and B6 showed clear inhibitory actions toward STEC,22 mm and 15 mm diameter of inhibition zone srespectively. W

Analysis of antimicrobial activity of root canal sealers against endodontic pathogens using agar diffusion test (In vitro study)
...Show More Authors

Background: Antibacterial action of root canal filling is an important factor for successful root canal treatment, so the aim of the study was to identify and to compare the antimicrobial effect of new sealer (GuttaFlow) to commonly used endodontic sealers (AH Plus, Apexit and EndoFill) against four endodontic microbes. Materials and methods: Twenty patients aged (30-40) years with infected root canals were selected. Four types of microorganisms were isolated from root canals (E faecalis, Staphylococcus aureus, E coli and Candida albicans) and cultured on Mueller Hinton agar Petri-dishes. After identification and isolation of bacterial species, agar diffusion method was used to assess the antibacterial action of four contemporary endodontic
