Potentials of Iron Oxide Nanoparticles (Fe3O4): As Antioxidant and Alternative Therapeutic Agent Against Common Multidrug-Resistant Microbial Species

     For the treatment of pathogenic bacterial infections, multidrug resistance (MDR) has become a major issue. The use of nanoparticles is a promising strategy for combating medication resistance in a variety of pathogens that cause deadly diseases. The goal of our research was to extract multidrug-resistant bacteria from wound infections and then use iron oxide nanoparticles (Fe3O4) as alternative therapeutic agents in vitro. Gram staining, morphological attributes evaluation, and biochemical testing were used to assess the microbes. The Kirby-Bauer disk diffusion method was used to test MDR-bacterial strains against several antibiotics; the majority of these isolates were resistant to ceftazidime, amoxicillin, Gentamicin, and tetracycline. the iron oxide nanoparticles were produced by the co-precipitation method and were confirmed by changing the color to dark black as well as the Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) analysis that shows the shape and average size between (29.03-56.54) nm. The highest effect of iron oxide nanoparticles (Fe3O4) on the growth of Proteus.mirabilis (P.mirabilis) was as it was found that the average diameter of the inhibition zone was 22.66±1.15 mm, followed by Staphylococcus.epidermidis (S.epidermidis), Acinetobacter.baumannii (A.baumannii) with the average diameter of the inhibitory zone it was 21.66±1.52 mm, 20.33±1.53 mm respectively, and Candida.albicans (C.albicans) was 18.33±1.15 mm at 100 µgmL-1 (stock). The synthesized iron oxide nanoparticles (Fe3O4) are used to capture rapidly microbes under the magnetic field effect. The antioxidant activity DPPH of the iron oxide nanoparticles (Fe3O4) showed 29.3%, 42.2%, 58.6%, 67.4%, and 74 % at a concentration (6.25, 12.5, 25, 50, 100) µgmL-1 respectively, it demonstrated that the scavenging percentage increase with increasing the iron oxide nanoparticles (Fe3O4) concentrations.

Detection of Salmonella In Some Red and White Frozen Meat Obtained From Local Market.

Background: Salmonella spp. are one of the most frequently reported causes of bacterial foodborne outbreak in the world.
Objective: This study has been conducted to detect salmonella as a major public health problem worldwide.
Methods: A total of 12 samples including 8 white meat (chicken) and 4 red meat (beef) samples were collected randomly from each sample; 25gr was separated and treated with 225ml of buffered peptone water, incubated at 37C°and 42C° for 24 hours. Samples were streaked on selective enteric agar.
Result: Totally 4 out of 8 chicken meat and one out of 4 red meat samples were contaminated with Salmonella spp.
Conclusion: These results confirmed the previous findings stating the proper packaging of meat prod

Optimal Dimensions of Small Hydraulic Structure Cutoffs Using Coupled Genetic Algorithm and ANN Model

A genetic algorithm model coupled with artificial neural network model was developed to find the optimal values of upstream, downstream cutoff lengths, length of floor and length of downstream protection required for a hydraulic structure. These were obtained for a given maximum difference head, depth of impervious layer and degree of anisotropy. The objective function to be minimized was the cost function with relative cost coefficients for the different dimensions obtained. Constraints used were those that satisfy a factor of safety of 2 against uplift pressure failure and 3 against piping failure.
Different cases reaching 1200 were modeled and analyzed using geo-studio modeling, with different values of input variables. The soil wa

Designing the Websites of the Iraqi Electronic Newspapers and its Role in Attracting Visitors

The researcher seeks to know the extent of applying the concept of design by Iraqi electronic press sites to provide media product with the acceptance of their browsers and ensure their repeated visits to such sites in the framework of the guiding rules for laser browsing. The researcher uses analytical study on a sample of six Iraqi electronic newspaper sites to identify the general features of their design and the methods of distribution of the structural elements of the pages. The researcher also conducts a field study on a sample of the surfers of electronic newspaper sites to see the extent of their evaluation to their design and the degree of their satisfaction.

Assessment of serum Interleukin-1β and its correlation with periodontal health status during pregnancy

Background: Pregnancy is a stressful state of increased inflammatory activity, and pregnancy – associated hormone changes can influence periodontal tissues, these inflammatory activity lead to production of inflammatory mediators. Interleukin 1 beta (IL-1β) is a potent pro-inflammatory cytokines that is consistently associated with periodontal diseases. This study was designed to determine the periodontal health status and detect the serum level of IL-1β in the healthy pregnant women at first, second and third trimester and compare it with healthy non pregnant women, and determine its correlation with different clinical periodontal parameters.

A Scoping Review of Machine Learning Techniques and Their Utilisation in Predicting Heart Diseases

Heart diseases are diverse, common, and dangerous diseases that affect the heart's function. They appear as a result of genetic factors or unhealthy practices. Furthermore, they are the leading cause of mortalities in the world. Cardiovascular diseases seriously concern the health and activity of the heart by narrowing the arteries and reducing the amount of blood received by the heart, which leads to high blood pressure and high cholesterol. In addition, healthcare workers and physicians need intelligent technologies that help them analyze and predict based on patients’ data for early detection of heart diseases to find the appropriate treatment for them because these diseases appear on the patient without pain or noticeable symptoms,

Assessment of Inflammation, Comorbidity and Demographic Factors in Patients with Kidney Disease in Baghdad

     Inflammation markers are significantly higher among hemodialysis (HD) patients, which have been associated with chronic activation of the immune system. Hemodialysis centers in Baghdad appear to be taking measures with low adequacy and frequency of dialysis sessions, which can be a reason for decreased kidney functions. Therefore, the objective of this study focuses on the assessment of different aspects of hemodialysis for regular HD patients in Baghdad, including inflammatory markers (serum C-reactive protein, CRP, and erythrocyte sedimentation rate, ESR), dialysis dose, comorbidities, and demographic factors for a period of one year (2018), the assessment covered four major hospitals in Baghdad namely (Al-Kind

Catalyzed and Promoted Direct Reaction of Ethyl Chloride with Silicon Using Stirred-Bed Reactor

In this paper a stirred-bed performed of the copper catalyzed synthesis of ethylchlorosilanes from silicon and ethyl chloride was described. A Si-catalyst mixture prepared by reaction of CuCl and Si was employed. The compositions of products were mainly ethyltrichlorosilane, diethyldichlorosilane, and ethyldichlorosilane and mainly depended on the extent of Cu in the mixture and the reaction temperature. A promoting effect on the extent of adsorption was observed on the addition of certain additives. The kinetic data revealed the direct depended of the reaction rate on C2H5Cl pressure.

Parameters Affecting the Strength and Behavior of RC Dapped-End Beams: A Numerical Study

The finite element method has been used in this paper to investigate the behavior of precast reinforced concrete dapped-ends beams (DEBs) numerically. A parametric investigation was performed on an experimental specimen tested by a previous researcher to show the effect of numerous parameters on the strength and behavior of RC dapped-end beams. Reinforcement details and steel arrangement, the influence of concrete compressive strength, the effect of inclined load, and the effect of support settlement on the strength of dapped-ends beams are examples of such parameters. The results revealed that the dapped-end reinforcement arrangement greatly affects the behavior of dapped end beam. The failure load decreases by 25% when
