the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
objective: vitrification has been shown as one of the most effective methods of cryopreservation for mammalian embryos. however, there is no consensus which stage of embryonic development is the most appropriate for vitrification with subsequent maximal development after thawing. this study was carried out to explore and compare the effect(s) of vitrification on mouse 2-cell, 4-cell, 8-cell, mo...
