The stability and equilibrium of the luminal microbial flora are significantly influenced by E. coli. The Escherichia coli uropathogenic-specific protein (Usp) represents type of genotoxins produced by uropathogenic E. coli rather than fecal E. coli isolates. In the current study E. coli was isolated from urine and stool and usp gene was detected in it. Sensitivity test was evaluated by using different types of antibiotics and the usp gene was detected by PCR in all bacterial isolates. Antibiotics sensitivity test showed variable degrees of sensitivity and resistance. High percentage of sensitivity was achieved against amikacin (86%) and that for ciprofloxacin, ceftazidime, gentamicin and tobramycin it was 80%. Whereas trimethoprim and aztreonam showed 64% and 60% sensitivity respectively. In this study, most isolates were resistant to amoxicillin 92%; while they showed different degrees of resistance against other types of antibiotics (from tetracycline 62% to amikacin 4%). The frequency of multi drug resistant (MDR) bacteria was about 64 % (32 isolates), 30 from urine and 2 from the stool. The results showed that usp gene was found in 26 bacterial isolates (52%), whereas other 24 (48%) isolates didn’t have this gene. It was concluded that source of bacterial isolates carry usp gene was urine, with the exception of one isolate from f stool, and E. coli recorded as multidrug resistant bacteria (MDR).","PeriodicalId":14698,"journal":{"name":"Iraqi Journal of Science","volume":"60 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140364907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The governing equations are transformed into a nonlinear ordinary differential equation using the appropriate similarity transformations. The resulting equations are solved by using the perturbation iteration method (PIT) to produce a convergent analytical solution with high accuracy. The phenomena of the squeezing fluid as the plates are moving apart and when they are coming together are illustrated using the resulting analytical solutions. Plots are used to discuss the significant effects of physical parameters on velocity, temperature, and fluid concentration profiles. The skin friction coefficient and Nusselt Sherwood values have graphical interpretations that are listed. For strong velocity slip parameters, the results demonstrate the existence of a minimum velocity profile close to the plate and a growing velocity profile distant from the plate. Additionally, as the slip effects rise, the fluid temperature and concentration both considerably drop. The results of the fourth-order Runge-Kutta method (RK4M) and the presented analytical solutions provided are in excellent agreement.","PeriodicalId":14698,"journal":{"name":"Iraqi Journal of Science","volume":"49 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140366827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to determine the impact of TiO2-NPs on HPV type 1 and 2 infections. The characterization of these NPs was performed using dynamic light scattering (DLS), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD). The MTT assay was used to determine the toxic impacts of TiO2-NPs on BHK-21 cells. The efficiency of TiO2-NPs was performed using several parameters, including TCID50 and RT-PCR assays. An indirect immunofluorescence assay (IFA) was performed to estimate the inhibitory impact of TiO2-NPs on viral antigen expression, and Acyclovir was used as a reference medicine. When the human papilloma type 1 and 2 viruses exposed to TiO2-NPs at high doses (100 μg/mL) produced 0.3, 1.1, 2.3, and 3.3 log10 TCID50 decreases in infective virus load when compared with control viruses (P<0.0001), these TiO2-NPs doses were related to 24.9%, 35.1%, 47.2%, 59.5%, and 66.6% inhibition percentages that were determined depending on the viral titer as compared to virus control. It is concluded that TiO2-NPs have strong potential for the treatment of face and labial lesions caused by papillomaviruses 1 and 2 and could be used in topical formulations.","PeriodicalId":14698,"journal":{"name":"Iraqi Journal of Science","volume":"42 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140368502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To manage any criminal behavior, we proposed electronic recording of the criminal behavior as the first step, then submitting the criminal with its behavior under proposed rehabilitation theories as the second step to examine the behavior enhancement. This rehabilitation system depends on the prize-and-penalty principle. The penalty in this system is a suspended sentence with community services and fines instead of prison punishment. The second proposed category is constructing the smart system techniques by automating the proposed “smart social system” as a part of the smart police organization under the smart city. The methodology suggests working as a training system to submit the criminals that should be going to prison in standard cases under the proposed rehabilitation system process within a specific period. The proposed system suggested three categories of behaviors into which a prisoner may fall; he might fall into the category of \"very bad people,\" where he needs to go to prison due to his worst actions. Second, he might fall into the \"very good person\" category, so this system suggests his prison punishment is now over and he is now free and can be released because he has enhanced his behavior. whereas the third category is the gradual process of a person whose actions lie in between these two characteristics; for this scenario, our proposed system suggests that this person needs rehabilitation and training to improve his behavior.\u0000A uniform crossover for the genetic algorithm has been implemented to check the performance of the proposed system. Thus, this could be very useful in improving the crime-preventing systems of the population in smart cities.","PeriodicalId":14698,"journal":{"name":"Iraqi Journal of Science","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140366569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evolutionary algorithms (EAs), as global search methods, are proven in the literature to be more successful than greedy methods in detecting protein complexes. However, the design of most of these EA-based approaches relies on the topological information of the proteins in the PPIN. Biological information, as a key resource for molecular profiles, on the other hand, acquired a little interest in the design of the components in these EA-based methods. The main aim of this paper is to redesign two operators in the EA based on the functional domain rather than the graph topological domain. The perturbation mechanism of both crossover and mutation operators is designed based on the direct gene ontology annotations and Jaccard similarity coefficients for the proteins. The results on yeast Saccharomyces cerevisiae PPIN provide a useful perspective that the functional domain of the proteins, as compared with the topological domain, is more consistent with the true information reported in the Munich Information Center for Protein Sequence (MIPS) catalog. The evaluation at both complex and protein levels reveals that feeding the components of the EA with biological information will imply more accurate complex structures, whereas topological information may mislead the algorithm towards a faulty structure.","PeriodicalId":14698,"journal":{"name":"Iraqi Journal of Science","volume":"46 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140367088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
