Membranous nephropathy (MN) is a podocytopathy characterized histologically by uniform thickening of the glomerular basement membrane due to the presence of subepithelial immune deposits. This disease can occur in a transplanted kidney as a recurrence of primary (Recurrent Membranous Nephropathy, RMN) or de novo disease.

Case report: 

A 40-year-old non-smoker man with a history of membranous nephropathy and resultant kidney failure, underwent a kidney biopsy 9 months after transplantation because of proteinuria of 4000 mg/day. Diagnosis of recurrence of membranous nephropathy in the transplanted kidney was made. The patient was given two doses of rituximab 1000 mg at a 15 day interval. Gradually, the amount of proteinuria decreased to 188 mg/day after 4 months, and his kidney function remained stable (creatinine 0.8 mg/dl) during the treatment.

 Membranous nephropathy can recur after kidney transplantation, and in cases of proteinuria more than one gram per day, we can use rituximab.

In the present study, the main purpose is the qualitative study on garbage collection in Tehran city. It has been done by qualitative research method. Semi-structured interview and purposeful sampling techniques were used in data collection. To do this, 15 people were interviewed and the sample size in the present study was determined based on theoretical saturation. Thematic analysis was used to analyze the data. Theme analysis was performed at 4 levels of primary, main, central and core themes. A total of 184 initial themes were extracted from all interviews. In the main coding stage, the following 9 main themes were merged. Escape from poverty in the origin and the inevitable choice of inferiority, society's view to garbage collectors, and high stress, strengthening the cycle of academic reluctance and illiteracy, physical and mental torment, unknown horizon and confusion of the Khojies, legal ambiguity and customary definitions and contracts, complaints from relevant institutions, the entry of the mafia and the formation of rent and corruption. Finally, these themes fall into two categories of social harmfulness of recycling and institutional exclusion and illegallity of the status of garbage collectors in the second distrect in the form of the core theme of the structure of socially harmful and institutionally illegal, waste phenomenon explained..

Human interaction with the environment in Iran came to thousands of years ago, but the environmental crisis is a recent phenomenon, which was caused by the lack of human awareness of environmental capacity.  In Iran, as in the rest of the world, some discourses have had a positive and negative effect on the crisis. Environmentalist discourse also took place in Iran like other parts of the world in response to this crisis. This discourse has tried in many ways to hegemonic itself and enter into a space of discursive struggle.  The purpose of this research is to study and analyze this discourse in Iran. In this regard, we consider environmentalism as an articulation, and analyze it through the Laclau's and MoffE's discourse analysis method. The results of the research show that, although the root of the discourse of environmentalism is too old, but due to the modernity of the environmental crisis, which has been markedly since the second Pahlavi, and as outcomes of the extreme development become clearer, this discourse today has become more powerful in dealing with this issue. After the revolution, with the continuation of development policies by various governments, this discourse has been articulating itself against this discourse, and has tried in various ways to hegemonic itself.

One of the important plans implemented by the Islamic Revolution's Housing Foundation in villages of Iran is the "Credits for Upgrading and Renovating of Rural Houses Plan". The plan was started since 2005. Villages of Dowlatabad district in Ravansar county were one of the targets for the mentioned plan. By the early 2012, a total number of 246 rural residents had received "the End of Work" certificate in Dowlatabad district. But the plan was implemented without any social impact's assessment. Therefore, it carried out both positive and negative consequences, some of which had not ever been foreseen. The present study applied a qualitative method for assessing the social impacts of such a project during 2005 to 2011. Semi-structured interview method was used for data collection and we applied the grounded theory method to analyze the information. We also used a theoretical and purposive sampling method with a sample size of 22, as the result of theoretical saturation. To analyze the information and construct the grounded theory, we completed three stages of coding (open, axial, and selective). The results of the research are presented in the form of a model that includes conditions (causative, interventional, background), strategies and actions / interactions and consequences. The results of the research indicated that despite some positive outcomes of the plan, it has had some negative consequences and unpredictable functions such as ignoring the elderly, change of livelihood, and migration. Such consequences would somehow be prevented or mitigated if a social impact assessment of the plan was already carried out.

Entrepreneurial learning is one of the most important focuses of entrepreneurship literature. Since entrepreneurs always have a pragmatic personality, they tend to reflectively learn from their own and others’ experiences. Reflective learning as a cognitive process roots in individuals’ personality characteristics. Therefore, it is important to know which of these personalities’ characteristics positively facilitate entrepreneurs’ reflective learning. Identifying and highlighting these personality traits can, in turn, facilitate designing an effective educational framework for developing entrepreneurs’ reflective learning ability. In order to reach this objective, the current study sought to answer to this question that “which Characteristics habitual entrepreneurs need to possess in order to learn reflectively?”. Further to this question, the current study explored the interdependencies amongst those personality traits highlighting the cause-and-effect relationships amongst them. Using semi-structured interviews and Interactive Management (IM) methods, 25 habitual Iranian entrepreneurs were engaged with this research and shared their thoughts and experienced with each other in a highly focused and structured system of collective intelligence brainstorming. The results of the current study indicate that ‘Positivity’, ‘Structured Mindset’, and ‘Job engagement’ are the most effective and influential personality traits which positively affect and facilitate reflective learning in entrepreneurs. The practical and theoretical implications of these findings are outlined in the manuscript.

In spatial data analysis، the variogram function that determines the correlation structure is usually unknown، and most estimates based on observations. The presence of outliers affect on the estimation of the variogram function، trend parameters and spatial prediction. In this paper some new robust estimators of variogram are presented. The proposed estimators have highly breakdown points and are based on scale estimators. All proposed estimators are assessed based on simulation studies. In addition robust methods of trend estimation and spatial prediction are presented. Finally، a real world problem about the average temperature of 170 cities in Iran is analyzed using discussed methods.

One of the important problems that bring up in genetic fields is determining of loci of special gene in order to gene mapping and generating more effective drugs in medicine. Genetic linkage analysis is one important stage in this way. Haseman-Elston method is a quantitative statistical method that is used by biostatisticians and geneticists for genetic linkage analysis. The original Haseman-Elston method is presented in the year 1972 and ever after many investigators recommended some suggestions to make better it. In this article, we introduce the Haseman-Elston regression method and its extensions through 1972 to 2009. and finally we show performance of these methods in a practical example.
