An Investigation of Post-radiation Gene Expression Profiles: A System Biology Study
Introduction: Genomics and bioinformatics are useful methods for exploring unclear aspects of radiation effects on biological systems. Many radiation-induced alterations in irradiated samples are post-radiation time-dependent. This study aims to evaluate the post-irradiation effects of the gamma-ray on human Jurkat cells.Methods: Gene expression profiles of the samples compared 6 and 24 hours after radiation to findthe critical differential expressed genes and the related pathways. Samples are provided from GeneExpression Omnibus (GEO) and analyzed by ClueGO.Results: Twenty-nine critical genes were determined as the important affected genes and 7 classes of related pathways were introduced. CCNE2, PSMD11, CDC25C, ANAPC1, PLK1, AURKA, and CCNB1 that were associated with more than 6 pathways were related to one of the determined pathway groups.Conclusion: Cell protecting pathways were associated with the genes (HSPA5, HSPA8, HSP90B1, HMMR, CEBPB, RXRA, and PSMD11) which were related to the minimum numbers of pathways. The finding of this study corresponds to repair processes that depend on post-radiation time. It seems these sets of genes are suitable candidates for further investigatio

Elderly and Care Givers’ Experiences of Transfer to Nursing Homes in Bam City: A Qualitative Study
Introduction: The elderly population has increased rapidly in recent decades, and consequently, admission to nursing homes is growing, but their experiences of this transfer have not been paid adequate attention. The aim of this study is to explain the elderly and care givers’ experiences of transfer to nursing homes in Bam city, Kerman Province, Iran.
Methods: This study was conducted using a phenomenological approach in 2017. Participants were the elderly residents in the nursing homes in Bam city and their care givers. Sampling was done till data saturation. Sixteen elderly people and 6 their care givers were participated in the study by purposeful sampling. Data collection methods were unstructured in-depth interview and field-notes. Data were analyzed by seven-stage Colaizzi's method.
Results: The data analysis identified 47 initial and conceptual codes that categorized the causes of transfer in 2 categories from the viewpoint of the care givers and of the elders and 4 sub-categories (the elders' problems, the family problems, compulsory transfer and voluntary transfer).
Conclusion: Participants' statements indicated that most elderly people were not happy with their transfer to nursing homes, although some are satisfy with their transfer. Therefore, formal and non-formal education should be offered regarding respect for the elderly, the use of their experiences, getting their satisfaction before transferring to the nursing homes, and regulating, meetings program with them by their family, friends, and even all sections of society as much as possible
Effectiveness of Neuropsychological Intervention on Reading Performance and Executive Functions in Dyslexic Children
The present study aimed to examine the effectiveness of neuropsychological intervention on reading performance and executive functions in dyslexic children. The research method was quasi-experimental. The statistical population of this study included all third grade dyslexic students who referred to the Learning Disabilities Centers in Zahedan in 2021. A total of 28 patients were selected by convenience sampling method and randomly assigned to experimental and control groups (14 people in each group). The neuropsychological intervention was performed in the experimental group for 15 one-hour sessions. Reading and Dyslexia Test (NEMA) (KaramiNouri & Moradi, 2005) and Behavior Rating Inventory of Executive Function (Gioia et al., 2000) was used to collect data. Multivariate analysis of covariance was used to analyze the research hypotheses. The results indicated that the neuropsychological intervention is effective on both reading performance (except for the elimination of sounds and words-fake reading) and executive functions (P <0.01). Furthermore, the results of repeated measures ANOVA showed that the results were significant in the follow-up phase (P <0.01). The findings generally indicated that the intervention can be used as an effective treatment of dyslexia in learning disabilities treatment centers
The use of sludge as a micronutrient for the improvement of biogas production from seaweed: the integration of two sources of environmental concern to bring new opportunities
Large quantities of seaweed in marine environments and coastal areas can cause serious hygienic and environmental problems. Anaerobic digestion (AD) could provide a solution and could also be useful for the production of bioenergy and fertilizer. However, the AD of algae biomass has some limitations and further work is required on the process. To increase the efficiency of the process, batches of 350 mL feedstock containing seaweed biomass (Sargassum sp.), inoculum, and different dosages of sludge from drinking water treatment (DWTS) as a micronutrient source to improve biogas production were digested in a 500 mL glass reactor and under mesophilic conditions, leading to significantly enhanced methane production. The highest methane yield (199 NmL g−1 VS) was observed when 6 mg L−1 DWTS was added, which showed a 30% improvement compared with the control digester and accounted for a 249.4 kWh increase in net energy per ton. The biodegradability index also increased by 10% compared with the control after the addition of DWTS
Application of superabsorbent geotextiles to decontaminate and improve crude oil-contaminated soil
The contamination of soil by various oil products is a severe geo-environmental problem. In this study, some geotextiles were used as superabsorbent geotextiles to decontaminate soil polluted with crude oil. The ability of these geotextiles to absorb oil is better than that of absorbing water. The removal efficiency of the absorbent geotextile was first evaluated by placing the spacer fabrics in different arrangements in contaminated soil samples. Second, the shear strengths of the decontaminated soil samples were evaluated through a series of direct shear tests and compared with those of contaminated soil. The effects of crude oil content, vertical stress, and geotextile arrangement were thoroughly investigated to understand the vivid behavior of the specimen matrix. The results showed that the geometric properties of geotextile and sand, such as the mean size of sand particles, aperture size, fluffs, and piles of geotextile, geotextile roughness, and the two phases occurring in the specimens – wettability and saturation of absorbent layer – are vital in determining the sand-geotextile interface and the behavior of shear strength parameters of the matrix. Ultimately, the results confirmed the efficiency of absorbent geotextile as a potential method for controlling soil contamination and improving the shear strength parameters
