this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Effect of Li+ on preimplantation mouse embryos.

Two-cell mouse embryos were cultured in vitro for different periods in a medium in which NaCl was partially replaced by LiCl at concentrations ranging from 1 to 30 mM. The relative cell number diminished according to increasing LiCl concentrations but the onset of blastulation was not affected, thus resulting in blastulae with fewer cells than normal and with a reduced or absent inner cell mass...

The Effect of Neurotoxicity of Mangane Chloride on Corpus Striatum of Mouse Embryos

Purpose: Manganese, are of the elements plenty & which is found in nature, is widely used in Agricalture and in dustry.For years, toxicity of magnasium and its derivatives has been proven yet the findings are not valid enough to overgeneralize the result to human.In the present study the effect of neurotoxicity of manganese chloride on the mouse cortex was investigated. Materials and Methods: ...

The Evaluation of Melatonin Effect on In-Vitro Development of Mouse Preimplantation Embryos

Purpose: Melatonin promotes in-vitro embryo development in different species. This study studied the effects of melatonin on in-vitro mouse preimplantation embryo development. Materials and Methods: Two-cell embryos were obtained from oviduct of 6-8 weeks female NMRI mice 48 hours after administration of an intra-peritoneal injection of 5 IU/ml pregnant mares’ serum gonadotrophin and subsequent...
