It is a further investigation on possible distributive dynamic of lectin receptors during the developmental process from generative cells to sperm cells. In the present study, all the three lectin receptors were found on the surface of generative cells of V faba and I. tectorium. However, on generative cells of H vittatum only Con A and WGA, but not SBA receptors were observed. The same lectin receptors on the generative cells from different species showed various distribution patterns. The distribution of various lectin receptors on the same generative cells also showed different characteristics. Lectin receptors were totally absent on some generative cells of all three investigated species. Polar distribution of lectin receptors was observed on tailed generative cells. The findings offer important clues to investigate sperm cell function and possible sperm dimorphism of surface glycoprotein.展开更多

However, there are many problems in rural col- lective land ownership registration and certification, such as unclear rural land own- ership subject and nature; not unified understanding of registration, no high enthusi- asm of the grass-roots work; prominent registration policy contradictions, serious shortage of investment, which seriously affect the rural land ownership registration work. In order to solve these problems, some suggestions are put forward on pro- moting the rural land ownership registration work smoothly.展开更多

The artistic, stylistic, and functional characteristics of one particular festival of the Bamana in Mali to celebrate the harvest and new planting season will be analyzed. This festival primarily takes on the form of animal masquerades in which masks, puppets, drumming, singing, and dancing are blended into a ritualistic celebration of a certain cultural identity. The Bamana culture has lost religion as a marker, as Islam is now the dominant religion in Mali, but traditional social relationships and morals among the Bamana as a patriarchal society are concretized and objectified by their animal masquerades. Apart from being a seasonal festival, events from the past are commemorated; customary gender roles are defined; and some fundamental and complex social concepts are reinforced by a performance mode which relies on a collective memory and oral transmission.展开更多

Therefore, it is necessary to culture the appearance and development of Internet Movie, is bound to the mode of expression, the people＇s cultural psychology and social individual to collective identity have significant influence.展开更多

Glucocorticoid receptor (GRs) activation in different regions of the brain affects reward-based reinforcement and memory processing. A wide array of studies have demonstrated that blockage of GRs in some brain areas can have an effect on reward-related memory; however, to date there have been no systematic studies about the involvement of glucocorticoids (GCs) in morphine-related reward memory. Here, we used the GR antagonist RU38486 to investigate how GRs blockage affects the sensitization and CPP behavior during different phases of reward memory included acquisition, retrieval and reconsolidation. Interestingly, our results showed RU38486 has the ability to impair the acquisition, retrieval and reconsolidation of reward-based memory in CPP and sensitization behavior. But RU38486 by itself cannot induce CPP or conditioned place aversion (CPA) behavior. Our data provide a much more complete picture of the potential effects that glucocorticoids have on the reward memory of different phases and inhibit the sensitization behavior.展开更多
