电生理技术在昆虫学研究中的研究进展

对电生理技术在昆虫毒理学、害虫抗药性、昆虫视觉等领域中的应用研究现状进行了综述,并讨论了电生理技术在昆虫学研究上的发展前景.     

整合素及其在昆虫学中的研究进展

整合素是一类存在于细胞表面的重要黏附分子,通过其双向信号转导途径,介导细胞-细胞外基质与细胞-细胞间的黏附,在哺乳动物的许多生理、病理过程中起重要作用。昆虫整合素的研究主要集中在其对果蝇的生长发育及鳞翅目等昆虫先天性免疫反应的影响。     

Scientists and congress

Scientists are urged to make their views known to members of Congress. To be effectively heard, they should establish personal contact with their congressmen and senators and their staff. Communication should be frequent, personal, and carefully focused. In the last 2(1/2) years, federal funding of scientific research has been severely cut back, while military research funding has been increased. The selection process for funding research is being politicized. Scientists should concern themselves with what is happening politically because the quality of American scientific research is being threatened.
