Background & Aims: Learning disorder is one of the most common neuro-developmental disabilities in childhood that requires effective interventions.The aim of this study was to compare the effect of tDCS and play therapy on improving attention and psycho-motor function in children with learning disorder.
Matherials & Methods: The present study was a semi-experimental (pre-test and post-test design with control group), and statistical population consisted of all the clients of Saqez educational center learning disorders in the academic year of 2016-2017. The research sample consisted of 30 primary and secondary school students who were selected by simple random sampling. Experimental groups received the intervention for 4 weeks (two sessions per hour per week) and the control group received their daily activities during the interventions. Before and after the end of the interventions, the attention and psycho-motor function of the subjects were measured by the continuous IVA test and Royan Oseretsky's motor test and the data were analyzed using the covariance test.
Results: The findings showed that both methods increased the attention and psycho-motor function in children with learning disorder, but this improvement was more significant in the tDCS method(p<0.05).
Conclusion: According to the findings of this study, parents, teachers, and all therapists are recommended to place tDCS in the educational programs along with therapeutic games.

Background & Aims: Extracellular vesicles are double phospholipid layer vesicles releasing from several cells. These particles contain bio-molecules including mRNA, miRNA, DNA, proteins, and lipids which play a pivotal role in the cell to cell communication. Once delivered, they participate to change target cell function, fate, morphology, differentiation, and growth. The present study is a review article conducted to study the molecular mechanisms involved in the exosomes biogenesis and their therapeutic applications.
Materials & Methods: In the present study, the articles indexed in Scopus, ISI, and PubMed databases were reviewed. Keywords such as extracellular vesicles, exosome, ESCRT, and MVB were used to search the studies. An assembly of 118 articles related to exosome published from 2000 to 2018, were studied.
Results: Exosomes, nano-vesicles ranging from 30-120 nm, are a subfamily of extracellular vesicles secreting from almost cells. The interacted molecular mechanisms involve in the formation, secretion, and uptake of these vesicles. Previous studies showed that exosomes have a pivotal role in the physiological and pathophysiological condition. The findings suggest that exosomes could be used as biomarkers and shuttles of therapeutic agents, especially in the case of diagnosis and therapy of diseases.
Conclusion: Exosomes actively participate in the control of biological processes. They can serve as a tool for diagnosis and therapy of various diseases. In spite of the progress in the biology of exosomes and their application, there are still more questions about their application.

Background & Aims: Acrylamide is an organic chemical with C3H5NO, which has been known to have carcinogens and fertility defects in male animals, humans and human nerves. This carcinogenic compound can be produced by heating the carbohydrates and high temperature cooked foods. Acrylamide can also be found in the main foods such as bread and potatoes, as well as in certain products such as chips, biscuits and etc. The average daily intake of this substance in body for males and females was 0.49 and 0.46 grams per kilogram of body weight, respectively. In spite of the requirement to measure this composition in the Food and Drug Administration, there is no method at this center for measuring this composition with the facilities available at the university. In this acrylamide design, the samples were first extracted and preconcentrated with modified cartridges and then they were measured by high performance liquid chromatography (HPLC).
Materials & Methods: For this purpose, in this experimental method, a variety of breads, biscuits, chips and chocolates were prepared from the city supermarket and acrylamide extraction in the samples were measured using HPLC with UV detector.
Results: Measurement of acrylamide in four types of products including chips, bread, chocolate and biscuits with 10 samples of each brand indicated higher amounts of acrylamide in some samples of chips and cacao biscuits and barbaric bread. It should be mentioned that amounts of acrylamide were at the limit and the highest amount of acrylamide was found in chips.
Conclusion: Results indicated that acrylamide levels are acceptable in most samples and this method can easily measure acrylamide at a very low cost compared to the GC-MS method and can be implemented in the laboratory with an HPLC device with UV detector.
