I. Information treatment for information services
Abstract

Objective: The purpose of this research was to identify and explain the service components of libraries and information centers based on information society criteria and dimensions of globalization. Methods: This applied qualitative research was conducted using the method of qualitative content analysis, grounded theory, and interview tools. The sampling method was purposeful. The research community consists of 22 experts in library and information science with the specialized field of information society, globalization, and evaluation of library services, with whom a semi-structured interview was conducted. Results: The findings of the interviews were presented in the form of axial coding and open coding in five sections: causal conditions, strategies, contextual conditions, intervening conditions, and consequences. The core codes for the causal conditions of the service components of libraries and information centers are: economic factors, production and organization of knowledge and information, infrastructural factors, etc. The core codes for the strategies of the service components of libraries and information centers include coordination and integration, planning Strategic, analysis of internal and external environments. The core codes for the background conditions of the service components of libraries and information centers include legal and economic factors, cultural factors, communication, and interactive factors, etc. The core codes for the intervening or modulating conditions of the service components of libraries and information centers are: budget and income factors, socio-cultural diversity, macro and management factors, etc. The core codes for the consequences of the service components of libraries and information centers consist of the development and exchange of communication, the development and strengthening of knowledge management, the strengthening of the library's position, the improvement of infrastructure, differentiated library services, and sustainable development, each of these core codes includes several subcategories (open codes). Conclusions: Several factors such as causal conditions, strategies, background conditions, intervening conditions lead to increasing or decreasing the efficiency of academic libraries. This will lead to positive consequences in the progress and development of these libraries if the strengths are strengthened and the weaknesses are eliminated. In this regard, it is expected that according to the criteria set for the information society, they will improve their performance, and according to global dimensions, they should provide a suitable ground for the research and educational activities of professors, students, and researchers. According to the obtained results, it can be said that it is very important for academic libraries and information centers to provide comprehensive services using modern technologies and in accordance with the standards of the information society and global dimensions.

Abstract

Metal oxide nanoparticles (NPs) are a member of nanomaterials family that have been produced on a large scale and their toxicity affected by their high surface-to-volume ratio. The hemolytic toxic effects of metal oxide NPs may be completely different from those observed in their bulk counterparts. So, the main purpose of this research was to measure the difference between the hemolytic effects of ZnO (NPs and bulk) on isolated human red blood cells (RBCs). Hemolysis was measured after incubation of human RBCs with 0.01–1 mM of ZnO (bulk and NPs) for 6 h. For measurement of other variables, human RBCs were treated with 0.1 mM of ZnO (NPs and bulk) for 1, 2, and 3 h. Our results demonstrate that bulk ZnO did not show any toxic effects in the concentrations tested, while ZnO NPs caused toxic hemolytic effects through formation of ROS, lipid peroxidation, and glutathione depletion.

40. Potential host range of Stilbocrea banihashemianaand susceptibility of economically important trees to this emergent fungal canker-causing pathogen

Abstract

Stilbocrea banihashemianais a recently described species of ascomycete fungi (Bionectriaceae) that causes canker and dieback diseases on fig and barberry, and dieback on loquat trees. Previous studies suggested this pathogen might affect other trees including economically important fruit crops, such as almonds, apples, and olives. This study assessed the susceptibility of 40 tree species belonging to 20 plant families, including fruit-bearing, ornamental, and edible landscape plants, to S. banihashemiana. The assessment was conducted by wound-inoculating detached shoots and one-year-old saplings with the pathogen.Based on five parameters of induced lesions, we clustered the inoculated tree species using the principal component analysis approach. The results of the approach revealed four distinct groups of tree species based on their susceptibility traits. Almond, apricot, eucalyptus, poplar, and red mulberry clustered in one group as susceptible hosts. The majority of the species examined, which included both tropical and temperate trees, were categorized as moderately susceptible. Platanus and sweet orange were identified as non-host-resistant species, while Arizona cypress, garden privet, and olive were classified as low susceptible. Moreover, our findings suggest a correlation between temperature and the aggressiveness of S. banihashemiana. This study revealed that the emerging pathogen, S. banihashemiana, could have a broader host range than currently recognized. The accidental introduction of this pathogen through the global trade of live host plants may pose a significant threat to economically important trees in temperate and subtropical regions.

Abstract

A delivery system was developed according to maillard reaction using mung bean protein and maltodextrin for encapsulation and sustain release of curcumin. The ultrasound assisted (150 W, 80 °C, 10 min) and classic wet heating (80 °C, 60 min), were used to prepare conjugates at three different ratios of Mung bean protein isolate to maltodextrin. Degree of conjugation was measured using OPA method Uv-visible spectroscopy was used to estimate the final products of maillard reaction. Different amounts of curcumin (0, 0.2, 0.4 and 0.6 mg. mL-1 was loaded using ethanol and change in pH. Primary analysis showed that the optimized samples were obtained when 0. 4 mg. mL-1 of curcumin was encapsulated using pH change method. FTIR spectra confirmed the conjugation of the MPI and MD and showed the electrostatic and hydrophobic interactions as well as hydrogen bonding are the main reasons of conjugates stability and curcumin encapsulation. The prepared curcumin containing conjugates under optimized method showed the higher DPPH radical scavenging activity. Our results showed that the release rate of encapsulated curcumin under simulated condition of gastrointestinal tract (GIT) was controlled and lower than that which encapsulated in mung bean protein.

Abstract

Sodium (E)-3-hydroxy-4-((2-hydroxynaphthalen-1-yl)diazenyl)naphthalene-1-sulfonate (Calcon, CAL), is employed for the first time as a reversible colorimetric chemosensor to detect and measure Ce3+ and H2PO4- sequentially in the aqueous medium. The detection process has two steps. The interaction of CAL and Ce3+ in the first step with a noticeable color shift from purple to blue. Further, the reaction between CAL-Ce3+ and H2PO4- shows a clear color return from blue back to initial purple similar to that for CAL. The UV-visible examination of this color return reveals that H2PO4- removes Ce3+ and restores CAL content. The results showed that CAL and CAL-Ce3+ had a strong binding affinity and adequate detection limits for the Ce3+ and H2PO4-, respectively. For Ce3+, the linear range and detection limit are 1.20 × 10-6-1.02 × 10-4 and 2.0 × 10-7molL-1, while for H2PO4-, they are 2.0 × 10-7-8.7 × 10-6 and 3.0 × 10-8 molL-1. Finally, we measured these two ions in real samples using this methodology. Furthermore, the examination of the suggested receptor's logical behavior revealed that it can operate as a colorimetric chemosensor of the INHIBIT type, receiving chemical inputs and producing a UV-visible absorbance signal as the output. If Ce3+ and H2PO4- inputs are added in proper order, the receptor may also function as a molecular "keypad lock.". [ABSTRACT FROM AUTHOR]
