A total of 47 samples were collected from different clinical specimens (urine, wounds, burns, sputum, blood, stools) during the period from November 2013 to
January 2014, only 18 isolates (38.29%) were identified as Klebsiella pneumoniae ,11isolates (23.4%) as E. coli , 9 isolates (19.1%) as S. aureus, 3isolates (6.3%) as Psedomonase spp., 2 isolates (4.2 %) as K. terrigena and 4 isolates (8.5%) as K. oxytoca. The results were shown the elevation of K. pneumoniae percentage among the bacterial isolates depending on cultural, microscopically, biochemically characteristics and confirmed by using the API 20E and VITEK 2 system . Also K. pneumoniae isolates were more frequently in sputum samples then burns, stools , urine, wounds ,and blood in different percentages (33.3%, 16.6%, 16.6%, 11.1%,
11.1%, 11.1%) respectively. The in vitro sensitivity tests of K. pneumoniae isolates against (19) antimicrobial agents were determined through disc-diffusion method. It was found that all isolates were 100% resistant to (Ampicillin /Cloxacillin, Amoxicillin, Carbencillin, Oxacillin, Penicillin G and Ceftazipime, whereas they indicated variable resistance to the other antibiotics used. While Amikacin , Gentamicin and Imipenem revealed that were the most effective drugs used in the present study. Moreover K. pneumoniae isolated from sputum, urine and blood samples are more resistant to antimicrobial agents at percentages (78.9%), the most resistance isolates, 6 isolates were selected .The molecular detecting of some capsular polysaccharide genes (cps) were investigated by using PCR specific primers. Genotyping of 6 selected K. pneumoniae isolates were indicated by using K1,K2 specific PCR primers. The results were shown ,that there is no isolate belong to K1 serotype, while 4 isolates (66.6%) are belonged to K2 serotype, and 2
isolates (33.3%) showed negative result for both K1/K2.
Superconducting compound Bi2Sr2-xYxCa2Cu3O10+δ were Synthesized by method of solid state reaction, at 1033 K for 160 hours temperature of the sintering at normal atmospheric pressure where substitutions Yttrium oxide with Strontium. When Y2O3 concentration (0.0, 0.1, 0.2, 0.3, 0.4 and 0.5). All specimens of Bi2Sr2Ca2Cu3O10+δ superconducting compounds were examined. The resistivity of electrical was checked by the four point probe technique, It was found th
The existing investigation explains the consequence of irradiation of violet laser on the structure properties of MawsoniteCu6Fe2SnS8 [CFTS] thin films. The film was equipped by the utilization of semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser. when the received films were processed by continuous red laser (700 nm) with power (>1000mW) for different laser irradiation time using different number of times a laser scan (0, 6, 9, 12, 15 and 18 times) with total irradiation time (0,30,45,60,75,90 min) respectively at room temperature.. The XRD diffraction gave polycrysta

They deliver the drug at the right time, action and in the right amount, which provides more benefit than conventional dosages and increased patient compliance. The drug is released rapidly and completely as a pulse after a lag time. These systems are beneficial for drugs with chrono-pharmacological behavior, where nighttime dosing is required and for the drugs having a high first-pass effect and having specific site of absorption in the gastrointestinal tract. This article covers methods and marketed technologies that have been developed to achieve pulsatile delivery. Diseases wherein PDDS are promising include asthma, peptic u

Background: This study was conducted to isolate and identify the bacterial isolates of neonatal septicemia in a Neonatal Intensive Care Unite in the Baghdad teaching hospital and the resistance of these locally isolates to different antibiotics. Suspected cases of neonatal sepsis which were not treated with any antibiotics were enrolled.
Methods: One to two milliliter of blood specimens were collected from these neonates aged from 3-7 days and cultured in Brain heart infusion broth.
Results: Out of 90 neonates, 15 ( 15.5%) were positive on blood cultures. Results showed that nine isolates have been obtained belonging to Klebsiella spp. comprising (60%) out of the total isolates followed by Staphylococcus aureus (27.7%)
In the present research, the chemical washing method has been selected using three chelating agents: citric acid, acetic acid and Ethylene Diamine Tetraacetic Acid (EDTA) to remove 137Cs from two different contaminated soil samples were classified as fine and coarse grained. The factors that affecting removal efficiency such as type of soil, mixing ratio and molarity have been investigated. The results revealed that no correlation relation was found between removal efficiency and the studied factors. The results also showed that conventional chemical washing method was not effective in removing 137Cs and that there are further studies still need to achieve this objective.
The aim of this study was to evaluate the anti mitotic activity of ether extract prepared from Datura stramoium plant on cancer cells. Recently oncology studies are directed toward substances which act somehow to induce apoptosis or to prevent abnormal dividing of cell, that may provide therapeutic strategies for the treatment of cancer. Thus, many research on various types of plants such as fruits, vegetables, other editable plants and toxic plants have been done in vitro and in vivo. But, few studies on Datura plant were occurred and there was no previous study dealing with its effect on proliferative activity of cancer cells. In current study, two types of common malignant tumor were tested in vitro. These were mamm

The level of the antimicrobial effects was established using an in vitro agar assay and minimum inhibitory concentration (MIC). In general ethanolic extract were more effective on gram positive bacteria than gram negative bacteria and strongest antimicrobial effect against Streptococcus pyogenes and Salmonella entritidis. Other tested bacteria and yeasts were sensitive to extract ranging from 4 to 16 mg/ml and more.
