Generally, there are two kinds of academic views towards Eve’s role. One side holds that Eve means the fertility of life and the other believes that Eve symbols the root of evil. This paper supposes to analyze the positive and negative identity of Eve in “Never Again Would Birds’ Song be the Same”, and it comes to the conclusion that this poem highlights the ambiguity and uncertainty of Frost’s poems.展开更多

Compared with the tra- ditional antidepressants that take weeks, if not months, to benefit patients and are associated with a high rate of relapse, ketamine exerts its antidepressant effects within several hours. These clinical benefits can last for 2 weeks after a single injection [1, 2, 4]. However, ketamine still has limited clinical application, psychotomimetic side-effects and liability of abuse. A recent paper in Nature [5] showed that the ketamine metabolite enantiomer （2R,6R）-hydroxynorketamine （HNK） has rapid and sustained antidepressant effects without the side-effects associated with ketamine, such as abuse potential. The discovery of （R）-ketamine is a land- mark in the field of depression. Investigations of its mechanism of action will inspire the development of a new展开更多
