Evaluation of trigonelline production in Trigonella foenum-graecum hairy root cultures of two Iranian masses

Abstract The production of the trigonellin by hairy root cultures of Trigonella foenum was described in two Iranian masses (Zanjan and Borazjan). Different Agrobacterium rhizogenes strains (A4, 9126 and 15834) and infection methods (co-coltivated and injection) were tested to investigate the ability for transformation and production of trigonellin in T. foenum. PCR analysis using rolb gene was used for identification of transformed hairy roots. All the strains of A. rhizogenes used in this study were able to produce hairy roots. The transformation efficiency was %26 in injection method for whole plants. The higher growth index was obtained in hairy roots induced by 2 strains, 15834 and 9126, in Zanjan and Borazjan masses, respectively. Detection and identification of trigonellin for a 28 days period was carried out by high performance liquid chromatography method. The highest amounts of trigonellin in Borazjan and Zanjan hairy roots were 14.89 and 14.03 mM g -1 DW after 28 and 7 days, respectively. The selection of an effective A. rhizogenes strain and T. foenum genotype for the production of trigonellin in transformed root cultures is important. This successful production of trigonellin may be used as a useful system for comparative studies of production capacity of trigonellin in different genetic resources T. foenum

Happiness and Willingness to Communicate in Three Attachment Styles: A Study on College Students

AbstractThe aim of this study was to investigate happiness and willingness to communicate in three attachment styles on college students. using cluster sampling method, 400 students were selected as sample. Hazan and Shaver‘s Adult attachment styles scale, Memorial University of Newfoundland Scale of Happiness (MUNSCH) and willingness to communicate scale were used for collecting of data. Data analysis using one-way analysis of variance (ANOVA) and post hoc multiple comparison were performed. the results showed that there are significant difference among attachment styles on happiness. Students with secure attachment style than non-secure have a higher happiness and student with avoidant attachment style compared with ambivalent attachment have a higher happiness. Another result showed that there are significant differences among attachment styles on willingness to communicate. Students with secure attachment style than non-secure students have a higher willingness to communicate and also students with ambivalent attachment style compared with avoidant students have a higher willingness to communicate. these results suggest that secure attachment style is a main factor in happiness and willingness to communicate of individuals

Presenting an integrated spatial-based model for flood hazard zoning, a case study: Maneh and Samalqan County

Due to the increase in the occurrence of floods, especially in the cities, and the emergence of human, financial, and environmental risks due to its increase, the flood zoning areas are of great importance. Therefore, in this study, it was tried zoning the areas of floods with the help of determining effective criteria. The criteria used in this research include Modified Fournier Index, Topographic Position Index, Curve Number, Flow Accumulation, Slope, Digital elevation model, Topographic Wetness Index, Vertical Overland Flow Distance, Horizontal Overland Flow Distance, and Normalized difference vegetation index. The novelty of this study is to present a new combination approach to determine the effective criteria in flood hazard zoning (Maneh and Samalqan County). In this regard, the combination of geographically weighted regression (Gaussian and tri-cube kernels) and binary particle swarm optimization algorithm was used. The recommended combination method is suitable for spatial regression problems because it is compatible with two unique properties of spatial data, i.e. spatial autocorrelation and spatial non-stationarity. The best value of the fitness function (1-R2) for Gaussian and tri-cube kernels were obtained 0.0745 and 0.0022, respectively, which indicates higher compatibility of the tri-cube kernel than the Gaussian kernel. It was also found that the criteria used have a significant effect on the rate of flooding in the study area

Investigating Successful International Experiences in Drought Management

Analysis of existing drought management policies in some countries, including Iran, indicates that decision-makers mainly react to drought episodes through a crisis-management approach, instead of developing a comprehensive and long-term policies. One of the comprehensive programs is the drought risk management model adopted in the member state of the European Union (EU), which is based on the EU Water Framework Directive (WFD). In the present study, the above-mentioned document along with the experiences of different countries faced with the drought crisis was analyzed in order to prepare a drought management plan for the country. This study is an applied research performed through library studies based on scientific and international resources. The results showed that in the process of drought management, creation of organizational capacity is the main factor to evaluate drought and its various effects on the community. This can only be achieved through the establishment of a Drought Independent Committee. On the other hand, drought management should be seen as a risk management process that emphasizes permanent monitoring of resources and observes climate change in the monitored area, rather than the onest of disaster as a crisis management. Drought management has been accepted by the international community in terms of risk management instead of crisis management. The proposed plan presented in this study is based on active drought management (risk management) that provides appropriate plans and preparedness for drought response, by offering long-term planning and forecasting

Factors affecting fall turnover in brackish lakes

This study investigates fall mixing in brackish lakes. Data from the Colomac Zone 2 Pit Lake is used to study the effects of salinity structure, and the ratio of runoff plus direct precipitation to evaporation (P*/E), on fall turnover. Zone 2 Pit Lake is currently not subject to turnover, but the model CE-QUAL-W2 is used to investigate conditions under which it, or other similar lakes, might turnover in fall. Accordingly, a curve is generated which separates meromictic and holomictic states for different combinations of salinity stratification and P*/E ratios given the bathymetry of Zone 2 Pit Lake, and the meteorological forcing it was subject to in 2010. It is shown that in brackish lakes, increases in the salinity of the surface layer due to evaporation can drive turnover.Applied Science, Faculty ofCivil Engineering, Department ofGraduat

COLOURS IN A BLACK WORLD Capturing the Voices of the Blind through the Development of a Radio Drama

Amongst people with disabilities, there are many unspoken stories worthy of an audience. Through the act of developing and performing a radio drama, this study aimed to capture the voices of those with vision impairment and blindness in order to share their unique perspectives to those within and beyond the academy. Four key themes emerged from this arts-informed inquiry in working with eight Persian participants with blindness as they work-shopped and then performed a radio drama titled Hope Springs Eternal. The first theme examined the negative cultural views and challenges faced by the participants living in a mainstream society that has little understanding of blindness. Demonstrating the constructed reality from the participants’ blindness subjectivity comprised the second theme. Reflections on how the process of creating Hope Springs Eternal helped to designate the participants’ sense of identity, both individually and collectively, is discussed as the third key theme. Finally, how the process of developing and performing Hope Springs Eternal facilitated an authentic community-building experience for the participants is explored. Although specifically grounded in the lived experiences of those with blindness, this study has the potential to be relevant to other disabilities

Trichoderma strains- Silybum marianum hairy root cultures interactions

Background and objectives: Silymarin is a unique flavonoid complex with documented hepatoprotective properties. Silybum  marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. In the present investigation Trichoderma strains- Silybum marianum hairy root cultures interactions have been studied. Methods: The effects of two Trichoderma Strains (KHB and G46-7) (0, 0.5, 1, 2 and 4 mg/ 50 mL culture) in 6 different exposure times (0, 24, 48, 72, 96 and 120 h) have been investigated on flavonolignans production. The flavonolignans were analyzed by High Performance Liquid Chromatography method. Cell signaling pathway was evaluated by determination of H2O2 content, peroxidase and ascorbate peroxidase activities. Results:The elicitation effects of two Trichoderma Strains (KHB and G46-7) were examined on flavonolignans accumulation and the activation of cell defense system in S. marianum hairy root cultures. The results indicated that the highest silymarin accumulation (0.45 and 0.33 mg/g DW) was obtained in media elicited with 0.5 mg/50 mL cultures of T. harzianum Strains (KHB and G46-3, respectively) after 120 h. Feeding time experiments indicated that a significant higher content of silymarin production was achieved after 120 and 72 h in media treated with 0.5 mg/50 mL cultures of KHB and G46-3, respectively. Our results showed that S. marianum treated by KHB strain, increased taxifolin, silychristin, isosilybin and silydianin productions significantly. The H2O2 content in the control hairy root cultures remained lower than the treated cultures. There was significant enhancement in both peroxidase and ascorbate peroxidase activities in treated hairy roots reaching a peak after 72 h. Conclusion: These findings suggested that some Trichoderma strains are positive elicitors for promoting silymarin accumulation in S. marianum hairy root cultures. The results also suggested the presence of H2O2 and oxidative burst induced by T. harzianum as a signaling pathway
