Background & Objective: Bacteria play a major role in urinary tract infections (UTIs); therefore, it is necessary to be aware of their regional prevalence and the causative pathogens for better prognosis and rapid treatment in clinical settings. This study aims to evaluate the prevalence of bacterial isolates involved in UTI samples and their antibiotics resistance pattern. Materials & Methods: In this cross-sectional study, bacterial infections from 4214 urine samples were analyzed from December 2016 to December 2018. After biochemical tests, disk diffusion susceptibility procedures were performed on all positive clinical cultures, according to CLSI guidelines. The obtained data were sorted and statistically analyzed by SPSS 26. Results: Out of 3582 suspected UTIs samples, 2006 (56%) were females and 1576 (44%) males in the 0-99 years old age range and mainly consisting of middle-aged and elderly patients (62.2%). Escherichia coli (53.43%) and Staphylococcus epidermidis (15.99%) were the most frequent isolates. Among gram negative bacteria, nitrofurantoin and among gram- positive, vancomycin represented the lowest resistance rates at 25.27% and 26.74% respectively. Piperacillin showed the least efficacy with a resistance rate of 76.04%, followed by cefazolin with a 74.94% resistance rate. In gram positive bacteria, vancomycin and gentamicin showed more promise with respective resistance rates of 19.34% and 27.34%. The highest resistance was associated with ampicillin (68.61%) and Trimethoprim/Sulfamethoxazole (66.06%). Conclusion: Alarming resistance rates were observed in ampicillin and piperacillin, which should be taken into account in therapy guidelines in this area. Prevalence of resistant strains can be avoided by developing appropriate healthcare policies and community awareness. [ABSTRACT FROM AUTHOR]

This research aims to design a Grounded Theory-based model for talent management for future Iran. Moving from the present to the future, the lack of human resources will become a serious problem for Iran. Therefore, to overcome the coming difficult days, it is necessary to identify and nurture the existing talent well, and since the best time to identify and develop talent is childhood, adolescence, and youth ages, and people are in school and university, at this age, so the education cycle is the best cycle for talent management. This research was conducted to compensate for the lack of human resources through optimal control of talent. The research method is sequential mixed (the qualitative section is preferred to the quantitative section). In the quantitative section, 10 expert professors were interviewed, and the results were analyzed through the Grounded Theory method and 122 codes were obtained as 6 axial categories. Then, the model was designed. The designed model was tested using a sample including 400 people and finally, suggestions were presented. [ABSTRACT FROM AUTHOR]

Ajowan (Trachyspermum Ammi L.) is one of the most important medicinal plants native to the Middle East and Iran. The antibiotic properties of its essential oils are related to the relatively high content of thymol. In this study, the possibility of hairy root production was investigated in a pre-experimental study considering many factors affecting transgenic efficiency, including explant type, immersion time, and the type of culture medium. Optimal conditions for the pre-experiment were set up based on the completely randomized design with seven Agrobacterium rhizogenes strains (A3, A6, A7, 4404, AATCC15834, R1000, A4) and six selected Ajowan ecotypes (Ardebil, Shiraz, Arak, Sarbishe, Qom, and Rafsanjan). The rootrelated morphological characteristics were measured to study the effect of main factors on the hairy root production and the bacterial strains in terms of hairy root induction. Based on the results, the highest percentage of hairy roots in Ardebil ecotype was induced by ATCC15834 strain (50%) and the lowest percentage was related to Rafsanjan ecotype induced by A6 (10%). The highest positive and significant correlation was observed in dry and wet weights (r=0.95), root frequency percentage and root length (r=0.80). The highest amount of phenolic compounds in hairy roots (240 mg/g dry weight matter) was associated with the Ardebil ecotype induced by strain ATCC15834. In this study, Shiraz and Ardebil ecotypes were identified as the best ecotypes, A4 and ATCC15834 strains as the most suitable strains, and suggested for future studies. [ABSTRACT FROM AUTHOR]
