The result appeared that E.coli with high percentage (22.7% ,27.2%)in nixed &single infection respectively followed by Ps.aeuroginosa (22.7% , 13.6%) and S.aureus (18.8% , 9.09%).   Interleukin 2 &Interleukin 8 concentration level was detected in serum by enzyme-linked immunosorbent assay(ELISA) and data were compared with control to compare the performance of each cytokins & results show no elevated , no significant decrease in level  in two cytokins, this leads  to an independent factors for the detection of urinary bladder cancer

Sequencing mixed-model assembly lines in just-in-time production systems

This thesis proposes a new simulated annealing approach to solve multiple objective sequencing problems in mixed-model assembly lines. Mixed-model assembly lines are a type of production line where a variety of product models similar in product characteristics are assembled. Such an assembly line is increasingly accepted in industry to cope with the recently observed trend of diversification of customer demands. Sequencing problems are important for an efficient use of mixed-model assembly lines. There is a rich of criteria on which to judge sequences of product models in terms of line utilization. We consider three practically important objectives: the goal of minimizing the variation of the actual production from the desired production, which is minimizing usage variation, workload smoothing in order to reduce the chance of production delays and line stoppages and minimizing total set-ups cost. A considerate line manager would like to take into account all these factors. These are important for an efficient operation of mixed-model assembly lines. They work efficiently and find good solution in a very short time, even when the size of the problem is too large. The multiple objective sequencing problems is described and its mathematical formulation is provided. Simulated annealing algorithms are designed for near or optimal solutions and find an efficiency frontier of all efficient design configurations for the problem. This approach combines the SA methodology with a specific neighborhood search, which in the case of this study is a "swapping two sequence". Two annealing methods are proposed based on this approach, which differ only in cooling and freezing schedules. This research used correlation to describe the degree of relationship between results obtained by method B and other heuristics method and also for quality of our algorithm ANOVA's of output is constructed to analyse and evaluate the accuracy of the CPU time taken to determine near or optimal solution.EThOS - Electronic Theses Online ServiceMinistry of Culture and Higher Education of the Islamic Republic of IranGBUnited Kingdo

Weight Reduction Perception and Practice among Female Students in Al-Azhar University-Gaza, Palestine

Objectives: The present study aimed to determine the frequency of weight reduction perception. Methods: A sample of 467 female students from Al-Azhar University in the Gaza Strip was selected on a convenience basis. Information obtained from the participants included: age, marital status, place of residence, employment status, health status, methods of weight reduction, sources of information about weight control, and current physical activities. Results: The present study found that 38.8% of female students had practiced weight reduction. The most prevailing attitudes for reducing weight described by the students was sports with 83.3%, followed by exclusion of some principal meals or principal nutrients (57.8%). It was found that 38.5% of the students did not practice any physical exercise. An inverse association was also present between the satisfaction about body weight and the practice of weight reduction

Preceding rule induction with instance reduction methods

A new prepruning technique for rule induction is presented which applies instance reduction before rule induction. An empirical evaluation records the predictive accuracy and size of rule-sets generated from 24 datasets from the UCI Machine Learning Repository. Three instance reduction algorithms (Edited Nearest Neighbour, AllKnn and DROP5) are compared. Each one is used to reduce the size of the training set, prior to inducing a set of rules using Clark and Boswell's modification of CN2. A hybrid instance reduction algorithm (comprised of AllKnn and DROP5) is also tested. For most of the datasets, pruning the training set using ENN, AllKnn or the hybrid significantly reduces the number of rules generated by CN2, without adversely affecting the predictive performance. The hybrid achieves the highest average predictive accuracy

Relationship between Borderline Personality Disorder, Emotional Availability, and Cortisol Output in Mother-Child Dyads

Background: Mothers with borderline personality disorder (BPD) often show altered emotional availability toward their own child and heightened stress vulnerability. The aims of the present study were (1) to examine total cortisol output in saliva during mother-child interaction in mothers with BPD and their children and (2) to test whether maternal nonhostility as a subscale of emotional availability mediates the relationship between maternal BPD and child total cortisol output. Methods: We investigated 16 mothers with BPD and 30 healthy control mothers (HC) and 29 children of mothers with BPD and 33 children of HC mothers. Children were between 5 and 12 years old. Salivary cortisol was collected prior to and twice after an episode of a 21-min standardized play situation between mother and child. Nonhostility was rated using the emotional availability scales. Analyses of covariance were computed to test for group differences in total cortisol output (measured with area under the curve with respect to ground). Pearson's correlation was calculated to test the association between maternal and child total cortisol output. To test the second question, a mediation analysis according to Preacher and Hayes was conducted. Results: Mothers with BPD and their children had lower total cortisol output. Maternal and child total cortisol output was significantly correlated. Contrary to our hypothesis, maternal nonhostility did not mediate the relationship between BPD and child total cortisol output. Conclusion: Results imply that the hormonal stress activity of mothers with BPD and their children is altered, which may reflect modified stress regulation and stress vulnerability in mother and child and may impact on mother-child interaction. The finding of a positive association between mother's and child total cortisol output could indicate an intergenerational transmission of these alterations

Physiological Biomimetic Culture System for Pig and Human Heart Slices

RATIONALE: Preclinical testing of cardiotoxicity and efficacy of novel heart failure therapies faces a major limitation: the lack of an in situ culture system that emulates the complexity of human heart tissue and maintains viability and functionality for a prolonged time. OBJECTIVE: To develop a reliable, easily reproducible, medium-throughput method to culture pig and human heart slices under physiological conditions for a prolonged period of time. METHODS AND RESULTS: Here, we describe a novel, medium-throughput biomimetic culture system that maintains viability and functionality of human and pig heart slices (300 µm thickness) for 6 days in culture. We optimized the medium and culture conditions with continuous electrical stimulation at 1.2 Hz and oxygenation of the medium. Functional viability of these slices over 6 days was confirmed by assessing their calcium homeostasis, twitch force generation, and response to β-adrenergic stimulation. Temporal transcriptome analysis using RNAseq at day 2, 6, and 10 in culture confirmed overall maintenance of normal gene expression for up to 6 days, while over 500 transcripts were differentially regulated after 10 days. Electron microscopy demonstrated intact mitochondria and Z-disc ultra-structures after 6 days in culture under our optimized conditions. This biomimetic culture system was successful in keeping human heart slices completely viable and functionally and structurally intact for 6 days in culture. We also used this system to demonstrate the effects of a novel gene therapy approach in human heart slices. Furthermore, this culture system enabled the assessment of contraction and relaxation kinetics on isolated single myofibrils from heart slices after culture. CONCLUSIONS: We have developed and optimized a reliable medium-throughput culture system for pig and human heart slices as a platform for testing the efficacy of novel heart failure therapeutics and reliable testing of cardiotoxicity in a 3D heart model

Towards transnational feminist queer methodologies

This article introduces the possibilities of transnational feminist queer research as seeking to conceptualise the transnational as a methodology composed of a series of flows that can augment feminist and queer research. Transnational feminist queer methodologies can contest long-standing configurations of power between researcher and researched, subject and object, academics and activists across places, typically those which are embedded in the hierarchies of the Global North/Global South. Beginning with charting our roots in, and routes through, the diverse arenas of transnational, feminist, participatory and queer methodologies, the article uses a transcribed and edited conversation between members of the Liveable Lives research team in Kolkata and Brighton, to start an exploration of transnational feminist queer methodologies. Understanding the difficult, yet constructive moments of collaborative work and dialogue, we argue for engagements with the multiplicities of ‘many-many' lives that recognise local specificities, and the complexities of lives within transnational research, avoiding creating a currency of comparison between places. We seek to work toward methodologies that take seriously the politics of place, namely by creating research that answers the same question in different places, using methods that are created in context and may not be ‘comparable'. Using a dialogue across the boundaries of activism/academia, as well as across geographical locations, the article contends that there are potentials, as well as challenges, in thinking ourselves through transnational research praxis. This seeks complexities and spatial nuances within as well as between places

Community pharmacy teams’ experiences of general practice-based pharmacists: an exploratory qualitative study

Background: In England, since 2015, there has been a formal drive to integrate pharmacists into general practice as a new healthcare service. Research efforts have offered insights into how general practice-based professionals and patients view the service, however, they took no account of community pharmacy teams’ opinions. There have been anecdotal statements about opposition from community pharmacies to the service, due to fears of losing business. The aim of the current study was to identify the experiences and perceptions of community pharmacy teams regarding pharmacists’ presence in general practice. Methods: The National Health Service Choices website was used to identify community pharmacies within a radius of two miles from eight West London general practices. The search resulted in 104 community pharmacies which were all contacted via telephone. Pharmacy staff who verbally expressed their interest to participate were then provided with the study’s documents. Qualitative, face-to-face, semi-structured interviews were conducted inside the pharmacy from which each participant was recruited. Interviews lasted 30 to 45 minutes and were audio-recorded. Audio-recordings were transcribed verbatim and transcripts analysed thematically. Results: Forty-eight community pharmacy staff participated. Four themes were discerned: awareness (“I knew that [pharmacists] have already been implemented [in general practice] but I haven’t really followed it…where does the pharmacist role come?”); interactions (“I’m just so pleased that there’s a pharmacist professional in the general practice…because we speak the same language!”); patient care (“if I was a patient knowing that there is a general practitioner and a pharmacist [in general practice], I would…think ‘nothing can go wrong at the moment’”); and funding challenges (“if general practices take on the extra responsibility of stop smoking or flu vaccination campaigns…financially, this would affect this pharmacy”). Conclusions: The current study revealed the perceived impact of general practice-based pharmacists on community pharmacies would be improved communication between pharmacies and practices. Findings will inform policy so that any future framing of pharmacists’ presence in general practice considers the needs of community pharmacies
