The capitate glandular trichomes of Oenothera glazioviana(Onagraceae) were collected with laser microdissection and analyzed by gas chromatography-mass spectrometry. The volatile compound 4-hydroxy-4-methylpentan-2-one(1) was identified. We found that compound 1 displays antimicrobial, insecticidal, and phytotoxic activities. These results suggest that compound 1 might function as a defensive compound in the capitate glandular trichomes of O. glazioviana against pathogens, insect herbivores, and presumably competitive plants as well.展开更多

The base of third metacarpal was found to be fractured with comminution of the capitate. The decrease in carpal height index and comminution of the third metacar- pal base lead to dilemma between conservative treatment and surgical management of this particular injury. The sur- gical management was chosen to maintain the carpal height index of the wrist to prevent the late degenerative changes.The patient was applied with external fixator in distraction mode expanning the wrist joint for six weeks, and the wrist was mobilised after removal of the fixator. It is shown that the external fixator in distraction mode expanning the wrist joint is a good alternative method for treatment of capitate fracture.展开更多

This paper aims to examine the role of race and gender in sustaining the capitalist world system through the lens of decolonial studies. It considers how both categories were historically constructed during the colonial process as tools to legitimize social, economic, and political hierarchies between the dominant and the dominated. In particular, the division of labor, based on racial and gendered distinctions, was instrumental in shaping these power relations. By analyzing these categories as central elements in the formation and maintenance of the capitalist world system, the study highlights their continued influence in perpetuating inequalities today.展开更多

文摘Glandular trichomes of plants produce a wide variety of secondary metabolites which are considered as major defensive chemicals. The capitate glandular trichomes of Oenothera glazioviana(Onagraceae) were collected with laser microdissection and analyzed by gas chromatography-mass spectrometry. The volatile compound 4-hydroxy-4-methylpentan-2-one(1) was identified. We found that compound 1 displays antimicrobial, insecticidal, and phytotoxic activities. These results suggest that compound 1 might function as a defensive compound in the capitate glandular trichomes of O. glazioviana against pathogens, insect herbivores, and presumably competitive plants as well.

文摘With a long-standing tradition in the development of critical theories, Latin America seeks, through a myriad of perspectives, to understand its peripheral position within the mechanisms of the world system. This paper aims to examine the role of race and gender in sustaining the capitalist world system through the lens of decolonial studies. It considers how both categories were historically constructed during the colonial process as tools to legitimize social, economic, and political hierarchies between the dominant and the dominated. In particular, the division of labor, based on racial and gendered distinctions, was instrumental in shaping these power relations. By analyzing these categories as central elements in the formation and maintenance of the capitalist world system, the study highlights their continued influence in perpetuating inequalities today.
