Introduction: Beta-actin is a housekeeping gene, which is used as an internal standard in various biological studies. Recently, it was reported that the expression of commonly used housekeeping genes including ß–actin changes in disease states or under certain experimental conditions. Based on the reports about the effects of sex hormones on the expression of the ß- actin gene, in this study...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
