Résumé
Background and objective: Breast cancer has high incidence among Iranian women and their long term survival lead to have more challenges with cancer complication. This qualitative study aimed to identify psychological responses following breast cancer
Materials and methods: A qualitative phenomenological method has been designed for the study. A sample of 11 women with breast cancer by purposive sampling selected and semistructured in-depth interviews were conducted. The interviews were transcribed verbatim,then Information have been analyzed during 5 steps using smith's method
Results: Two main themes emerged from the interviews included basic reactions and residual reactions and The following six sub themes of despair of life, trying to find a guilty, social isolation, irritability-sensitivity, feeling incompetence and fear of disease recurrence has been determined
Conclusions: Although breast cancer is a physical disease but it has great impact on a person's mental health. Also So many psychological problems caused by breast cancer and its treatment, remains until many years after completion of therapies
Résumé
Vertical distribution of microbial communities in a eutrophic lake sediments of Lake Xuanwu was quantified by phospholipid fatty acids analysis and multivariate statistical analysis was employed to interprete the data. Principle component analysis of sediment characteristics parameters, including total nitrogen, total phosphorus, organic matters and pH produced clustering of sampling sites for two distinct groups. These groups corresponded with the two sampling stations and the levels of nutrient enrichment. Total phospholipid fatty acids concentration, which is indicative of microbial biomass, reduced with depth, however, the relative percentage of anaerobic prokaryotes increased. To assess changes of microbial community along depth, phospholipid fatty acids compositions were analyzed by cluster analysis. Distinct clusters were observed in different sampling stations. Canonical correspondence analysis was carried out to infer the relationship between sediment characteristics and microbial communities. Phospholipid fatty acids samples collected at the same sampling site clustered together. Canonical correspondence analysis revealed that the environmental parameter with the greatest bearing on the phospholipid fatty acids profiles was pH. This study proved the successful application of phospholipid fatty acids and multivariate analysis to investigate the relationship between environment factors and microbial community composition
