Background and Aim: Occupational Performance Coaching (OPC) is a solution-focused, family-centered intervention that consists of three main domains: emotional support, information exchange and a structured process. OPC helps client with stroke to participate in their meaningful activities as before. Materials and Methods: We reviewed the databases such as Google scholar, ProQuest, PubMed and Science Direct. The studies that described OPC and used OPC as the intervention for stroke survivors included. The present information is available reviewing the articles from 1996 to 2019 through the search of the resources. Results: In the few available studies, the primary efficacy of this approach has been confirmed. OPC in people with stroke showed moderate to large effect in performance and cognition, respectively. Conclusion: Preliminary findings support using OPC in client with stroke. In this approach the clients are guided to solve their problem independently so far as possible.

Recent research in the area of Second Language Acquisition has proposed that bilinguals and L2 learners show syntactic indeterminacy when syntactic properties interface with other cognitive domains. Most of the research in this area has focused on the pragmatic use of syntactic properties while the investigation of compliance with a grammatical rule at syntax-related interfaces has not received due attention. In this study, the compliance of 67 Persian native speakers and 52 Persian speaking L2 learners of English with the Overt Pronoun Constraint (OPC, henceforth) a proposed UG principle, at the syntax-pragmatics interface is investigated. Both groups of participants demonstrated violations of the OPC at the syntax-pragmatics interface. It is argued that the results of this study both confirm and complement Sorace and Filiaci’s (2006) Interface Hypothesis while showing that difficulties at interface contexts are more a result of interface complexities than cross-linguistic influence.

This paper presents the results of an experimental study on the properties of environmentally friendly concrete. In the making of specimens, 0%, 15%, and 30% of ordinary Portland cement (OPC) was replaced by recycled concrete powder (RCP) and silica fume (SF). In addition, 0%, 50%, and 100% of natural aggregates (NA) was replaced by recycled concrete aggregates (RCA). In the production of RCA, 3 types of concrete waste with initial strength of 20, 40, and 80 MPa were used. In this study, rheological, mechanical (compressive, splitting tensile and flexural strengths), economic and environmental (GWP) properties of 28 mix designs were investigated. The results showed that the use of RCA and RCP has a negative effect on rheological and mechanical properties. However, the results showed that the use of RCA and RCP has a positive effect on environmental and economic properties. Moreover, the results indicated that the negative effect of RCA can be prevented by increasing the initial strength of RCA, and the negative effect of RCP can be prevented by using SF. Finally, by optimization of mixing designs, it was concluded that it is justified to use 50% of RCA with initial strength of 40 and 80 MPa and 30% of RCP and SF, in terms of rheological, mechanical, economic and environmental properties.

Objective: Spinal cord injury can lead to death of oligodendrocytes and axonal demyelination. It has been shown that mature oligodendrocytes are incapable of repair the demyelination after injury to myelin and oligodendrocyte progenitor cells (OPCs) have capacity of myelin repair. Studies demonstrated that they must be differentiated to the myelinating cells in order to result in remyelination. In this study, we examined differentiating potential of mouse embryonic stem cells (ESCs) generated through somatic cell nuclear transfer into oligodendrocyte progenitor cells.Materials and Methods: In this research, we used S1 nuclear transfer embryonic stem cell (NTESc), GFP+ gifted from stem cell technology research center. NTESc derived from this colony were cultured on inactivated mouse embryo fibroblasts (MEFs) as a feeder layer. After forming embryoid bodies, those EBs are disaggregated and plated on OPC medium culture containing of retinoic acid for 4 days. Gene expression evaluated by Real Time PCR and flowcytometry.Results: Embryoid bodies formed from these colonies. The purity of oligodendrocyte progenitor cell (OPCs) was high. The oligodendrocyte progenitor cell markers (Olig2, NG2) were increased and a decrease in expression of mature oligodendrocyte marker (MBP) was observed.Conclusion: We found that NTESC that are produced by therapeutic cloning have high differentiating ability to produce oligodendrocyte progenitor cells Therefore, this technique may facilitate maintenance, culture and differentiation of stem cells and OPC produced through this way might be used to reconstruct injury site. It has been considered as an efficient therapeutic strategy in spinal cord injury.
