On the contrary, the humanist movement focused more on human morality and wisdom. In The Merchant of Venice, Shakespeare placed an ideal of new humanist woman—Portia, who became a towering character in Shake-speare's works. From her, the spirit of pursuing love and human right can be revealed completely, influencing the development of humanism profoundly.展开更多

The final success of the lovers in their struggle for the freedom to decide their marriage not only embodies Shakespeare's humanist ideal but also reflects his firm belief that humanism would inevitably triumph over feudalism.展开更多

Moreover, the core of people-oriented thinking in humanism can be integrated with the quality education thought advocated by contemporary China. Therefore, in this context, the paper analyzes English education should focus on the integration of humanism. Firstly, the paper gives a brief overview of the meaning of humanism, and then summarizes the role of humanism in the full integration of English education. Finally, it analyzes in detail how to effectively integrate humanism into English education. The purpose of this study is mainly to improve the current level of English education, and to train comprehensive quality talents for the country.展开更多

All metazoan organisms possess integrins, and it is generally agreed that integrins were associated with the evolution of multicellularity, being essential for the association of cells with their neighbors and surroundings, during embryonic development and many aspects of cellular and molecular biology. Integrins have important roles in many aspects of embryonic development, normal physiology, and disease processes with a multitude of functions discovered and elucidated for integrins that directly influence many areas of biology and medicine, including mammalian pregnancy, in particular implantation of the blastocyst to the uterine wall, subsequent placentation and conceptus(embryo/fetus and associated placental membranes) development. This review provides a succinct overview of integrin structure, ligand binding, and signaling followed with a concise overview of embryonic development, implantation, and early placentation in pigs, sheep, humans, and mice as an example for rodents. A brief timeline of the initial localization of integrin subunits to the uterine luminal epithelium(LE) and conceptus trophoblast is then presented, followed by sequential summaries of integrin expression and function during gestation in pigs, sheep, humans, and rodents. As appropriate for this journal, summaries of integrin expression and function during gestation in pigs and sheep are in depth, whereas summaries for humans and rodents are brief. Because similar models to those illustrated in Fig. 1, 2, 3, 4, 5 and 6 are present throughout the scientific literature, the illustrations in this manuscript are drafted as Viking imagery for entertainment purposes.展开更多
