Antibacterial action of AgNPs produced from different isolates of Gram positive and Gram-negative bacteria on biofilm of Klebsiella pneumoniae isolated from RTI
...Show More Authors

Introduction and Aim: Klebsiella pneumoniae is a Gram-negative bacterium responsible for a wide range of infections, including respiratory tract infections (RTIs). This research was aimed to study the antibacterial and anti-biofilm effect of AgNPs produced by Gram positive and negative bacteria on RTIs associated with K. pneumoniae.   Materials and Methods: The biofilm formation of K.  pneumoniae was determined by tube method qualitatively from select bacterial species characterized by UV-Visible spectroscopy. The antibacterial susceptibility of the bacteria AgNPs was tested for their antibacterial and antibiofilm activity on a clinical isolate of K. pneumoniae.   Results: K. pneumoniae isolated from RTIs were strong biofilm producers.  The antibacterial activity of AgNPs synthesized from bacterial spp in this study had good antibacterial activity against K. pneumoniae. P. aeruginosa and P. mirabilis AgNPs had the strongest anti-biofilm effect, with 84% and 83%, respectively, while A. baumanii's AgNPs had the lowest (79%). AgNPs of P. aeruginosa and P. luteola showed the highest (80%) anti-biofilm action against the development of pre- and post-mature biofilms formed by K. pneumoniae, while AgNPs from S. mitis exhibited the lowest levels (69%).   Conclusion: AgNPs generated by Gram positive and Gram-negative bacteria, when exposed to K. pneumoniae isolated from RTIs had a good antibacterial impact and inhibited the formation of biofilm by K. pneumonia and hence could be used as an antibacterial agent against K. pneumoniae infecting the respiratory tract.

The Deliberative Action in the Labor Market of Iraqi Art The Concepts and the Application: شيماء وهيب خضير
...Show More Authors

The analysis of the orientations of Iraqi art commodification contributed to the discovery of deliberation, which was founded in the deliberative discourse in the trends towards commodification in the Iraqi art, since the important transformations in social structures and relations produced a dictionary with new vocabulary and tools that replaced the traditions and norms that have been in circulation for a century. Deliberation and commodification have become more prevalent in the mechanics and trends of the art where the pace of change is becoming increasingly frantic towards the market. The general market for art constitutes one of the most effective phenomena within contemporary art, that there has been a proliferation of sales auctio

THE ROLE OF EFFLUX PUMP FOR ANTIBIOTIC RESISTANCE IN BACTERIA: THE ROLE OF EFFLUX PUMP FOR ANTIBIOTIC RESISTANCE IN BACTERIA
...Show More Authors

ABSTRACT                

The multi-drug resistant efflux pump is a glycoprotein pump whose function is to push foreign substances. The efflux pump is found in humans, animals. It also has wide-ranging properties in  bacteria and fungi. They are found in all species of bacteria, and efflux pump genes can be found in bacterial chromosomes or mobile genetic elements, such as plasmids. The most sensitive function that leads to a global problem is its resistance to antibiotics in bacterial cells, which increases the ability to bacteria from becoming strong virulence factors that most or all antibiotics cannot kill. It also has othe

Multiple Sclerosis is a Risk Factor for Hyperthyroidism and Interferon Beta Action on Thyroid Hormones via Novel Immuno-neuro-enzymological Mechanisms
...Show More Authors

Objective : Multiple sclerosis (MS) is a common neurological disease deeply linked with the immune-inflammatory disorders whereas the term (multiple) mostly refers to the multi-focal zones of Inflammation caused by lymphocytes and macrophages infiltration besides oligodendrocytes death. Accordingly , the dysfunctional immune system able to damage myelin ( a pivotal component of the central nervous system ) which responsible for communication among neurons. The aim of the present study is to innovate a biochemical relationship between MS and thyroid hormones (THs) by highlighting immunological responses and also to examine the action of Interferon beta (IFNβ) drug on thyroid hormone (THs) and thyroid stimulation hormone (TSH). Materials and

Modification, Characterization of New Thiazolidinone and Oxazolidinone Derived from Levofloxacin and Evaluation of Anti-Oxidant
...Show More Authors

The research study included the synthesis of a new series of heterocyclic derivatives containing the antibiotic Levofloxacin. The first way provides for the reaction of  Levofloxacin with thionyl chloride in benzene as a solvent to give an acid chloride derivative. A new class of acid hydrazide synthesized from Levofloxacin was studied. Schiff bases were produced via the reaction of acid hydrazide with substituted aromatic ketones in methanol. The next stage involved the response of Schiff bases with thioglycolic acid and mono chloroacetic acid in DMF to produce derivatives of the antibiotic levofloxacin that have five heterocyclic members, including the derivatives thiazolidine-4-one and oxazolidine-5-one. The FTIR, 1HNMR, a

Summary:
Background: The acute lymphocytic leukemias (All) make up about 76% of children leukemias . lymphoid leukemias occur more often than expected in patients with immunodeficiency , chromosomal abnormalities & ataxia telangiectasia . A number of chnges occur in preneoplastic & neoplastic cells as the progress towards a greater degree of malignancy . Nuclear DNA may be used as an aid in diagnosis , to predict prognosis & to determent of certain neoplasia.
Aim of the work: is to purify DNA from whole blood of predict & normal children & to characterize it by spectral studies.

Bacterial Biodegradation of Congo Red Dye Using Local Bacterial Isolates
...Show More Authors

     The current study aims to get local bacterial isolates isolated from wastewater samples, w the highest ability to decolourize one selected Azo dye (Congo red as a model), and then test its ability to decompose Congo red dye, to obtain the most efficient bacterial isolate

Four samples of wastewater collected from sewage transport pipes were used for the bacterial isolation. Forty-two bacterial isolates were obtained after inoculating these samples in the liquid MS medium, pH 7 with 1% glucose, and then on solid MS medium supplemented with50 ppm of Congo red dye. Results from primary tests showed that only eighteen bacterial isolates own varying abilities to decolourize Congo red dye and the isolates WR7, WR18 and WR30 give

Molecular Detection of Suspected Leishmania Isolates Using Polymerase Chain Reaction
...Show More Authors

Leishmaniasis is a widespread parasitic disease that occurs as a result of infection with a unicellular parasite belonging to the genus Leishmania. Diagnosis by conventional methods is inaccurate and is not sensitive to confirm the genus infection. Here, we have investigated a methods for Leishmania genus diagnosis, which includes the technique of polymerase chain reaction to detect the presence of the parasite at in vitro for promastigote cultures using three genus-specific primer pairs to amplify HSP70, ITS, and ITS2. The results showed single band of ~1422, ~1020, and ~550 respectively. This study has proved the ability of these primer pairs to detect Leishmania infection and recommend them to be used for detection of leishmaniasis in
