The current study examines the representation of gender stereotype in English as a Foreign Language (EFL) textbooks, namely Guess What, for elementary school pupils produced in Uzbekistan. The research aims to ascertain how gender is represented and what kinds of stereotypes expressions are used in the Guess What series by focusing on four areas; Adult Social Role Beliefs, Domestic Role Beliefs, Educational Role Beliefs, and Professional Role Beliefs concerning school type variables. The method used in this research was descriptive qualitative method. Language is not perceived only orally or in written forms, but through visual language too, such as pictures on posters, images in books, magazines. They are ubiquitous in modern life and are of great importance to get the message, as they convey and represent particular meaning (Fairclough, 2013). English language teaching materials, which are one of the main sources of target language and culture input, have a great impact in the formation of pragmatic competence and the development of relational identity.
Abstract: In this research, the results of the effects of vincamine hydrochloride and pyrozalin iodide alkaloids on the relaxation of aortic smooth muscle cells in the presence of Ca2+ L-channels have been reported. The isometric contraction activity of the aortic blood vessel smooth muscle derived from rabbits was studied using mechanography. The results, under in vitro conditions, demonstrated that the contraction activity of the rabbit aortic blood vessel smooth muscle preparation induced by 50 mM KCl was dependent on the potential of the plasma membrane, associated with the activity of the Ca2*L-channels. It was found that vincamine and pyrozalin iodide alkaloids affected the blockage of the Ca2+i-channels and a reduction in [Ca2*] concentration. The obtained results suggest that the relaxing effect of vincamine hydrochloride and pyrozalin iodide alkaloids is based on the blockage of the L-type Ca2+ channels, and they also affect the receptor-operated Ca2+ channels. In conclusion, the results indicate that in providing the relaxing effect of vincamine and pyrozalin iodide alkaloids, the blockage of potential-dependent L-type Ca2t channels, along with the blockage of receptor-operated Ca2+ channels plays an important role.
