Formulating the strategy of prevention and control of crisis in Ministry of Education in Tehran

Organizational crisis provides conditions that cause the routine activities to face temporary or pretty permanent pauses. Crisis consists of the situation that interacts with the discipline of main system or final part and distracts its stability. There are different factors in the occurrence of organizational crisis that considering them can help avoiding such crisis. The crisis in the organizations is more because of the internal environment insufficiency and the lack of managerial success for facing or causing crisis and their prevention, identification of the factors causing crisis is significant in the first step and accordingly, the formulation of the related strategies, decision making and its implementation in the organization. Since most of the problems of Ministry of education and crisis are inter-organizational, and up to now there is no initial pattern for identification of the factors and defensive strategies within this organization, the goal of this research is to identify the general indicators of prevention from causing the crisis to formulate the technical strategies in Ministry of Education. This survey research is based on simple-random sampling. The total population were 180 workers, managers and the specialists of central staff of Ministry of Education, among whom, 120 individuals were selected based on Cochran formula. The prevention indicators and crisis control have been prioritized via AHP method. The results of the research indicated that the situation of this organization is located in defensive zone. Finally, some recommendations were declared regarding this approach

Ras signaling regulates osteoprogenitor cell proliferation and bone formation

During endochondral bone development, osteoblasts are continuously differentiated from locally residing progenitor cells. However, the regulation of such endogenous osteoprogenitor cells is still poorly understood mainly due to the difficulty in identifying such cells in vivo. In this paper, we genetically labeled different cell populations of the osteoblast linage using stage-specific, tamoxifen-inducible Cre transgenic mice to investigate their responses to a proliferative stimulus. We have found that overactivation of Kras signaling in type II collagen-positive, immature osteoprogenitor cells, but not in mature osteoblasts, substantially increases the number of their descendant stromal cells and mature osteoblasts, and subsequently increases bone mass. This effect was mediated by both, the extracellular signal-regulated kinase (ERK) and phosphoinositide 3 kinase (PI3K), pathways. Thus we demonstrate that Ras signaling stimulates proliferation of immature osteoprogenitor cells to increase the number of their osteoblastic descendants in a cell-autonomous fashion

Assessment of neurobehavioral disorders in workers exposed to organic solvents in a publication house

Background: Organic solvents are known as a group of organic compounds, widely used in industry and to which many workers are exposed. Neurotoxicity is one of the most important complications of the chronic exposure to the solvents and may causes neurobehavioral disorders in workers. We have studied the frequency of neurobehavioral disorders in workers exposed to organic solvents in one of the publishing houses in Tehran. Methods: In this cross-sectional study, 510 workers of a publishing house, having been employed at least a year before the research, were selected to be studied. Among them, 345 workers had been exposed to organic solvents and the other (165 workers) had not. Data were collected using a questionnaire. This questionnaire included demographic and occupational information, and the Swedish Q16 questionnaire. Variables included age, duration of employment, working shift, and smoking. Then we compared both groups in terms of neurobehavioral disorders, using statistical methods. Results: The mean score of the Swedish Q16 questionnaire in the exposed group (4.8±4.4) was significantly higher than the non-exposed group (3.2±3.1) (p=0.001). According to the questionnaire score, the frequency of neurobehavioral disorders in the exposed group was 38 and in the non-exposed group was 22 (p=0.001). We estimated that the frequency of neurobehavioral disorders in the exposed group was significantly higher than the non-exposed group (p<0.05) using regression analysis and removal of the confounding factors. Conclusion: This study shows that the frequency of the neurobehavioral disorders in the exposed group is significantly higher than the non-exposed group

Chemical composition and antimicrobial activities of the essential oil from Myrtus communis leaves

Abstract: Nosocomial pathogens are associated with increased hospital stay lengths and mortality rates. Increasing resistance to antibiotics makes the treatment of these infections more difficult. Novel antimicrobial compounds derived from natural sources may be useful for addressing antiobiotic resistance. The objective of this study is to determine the chemical composition and antimicrobial activities of essential oils from Myrtus communis L. (Myrtaceae) leaves against pathogens causing nosocomial infections. The chemical composition of essential oil from M. communis leaves was analysed by gas chromatography-mass spectrometry (GC-MS). The antimicrobial activity of the essential oil against bacteria and fungi was evaluated by broth micro-dilution as per the Clinical and Laboratory Standards Institute (CLSI) methods. GC-MS analysis revealed that the major constituents of the essential oil were α-pinene (39.2 %), 1,8-cineole (22.0 %), and linalool (18.4 %). The essential oil exhibited antimicrobial activity against all Gram positive and Gram negative bacteria with MICs in the range of 0.5-32 μL/mL and 8-64 μL/mL, respectively. MICs for the tested clinical and standard fungi were in the range of 0.03-16 μL/mL. The essential oil exhibited strong antibacterial and antifungal activities against all the causative agents of nosocomial infections examined, particularly against strains with antibiotic resistance. The essential oil from M. communis leaves is a potential source of novel antimicrobial agents for the treatment of nosocomial infections
