The relatively low susceptibility ofHelicoverpa armigera to CrylAc, its history of resistance to chemical insecticides and the seasonal decline in expression of CrylAc in transgenic cotton necessitated the development of cotton expressing two insecticidal proteins to provide sustainable control of this multinational pest. To manage the resistance issue, it was essential that the second insecticidal protein have a significantly different mode of action to CrylAc. A common feature of resistance to CrylA proteins in several species as well as H. armigera has been a change in the binding site. A study of binding sites for some Cry proteins in the brush border membrane vesicles （BBMV） ofH. armigera and Helicoverpa punctigera was undertaken. The binding affinity for CrylAc was higher than for CrylAb, matching their relative toxicities, and CrylAc and CrylAb were found to share at least one binding site in both I-1. armigera and I-1. punctigera. However Cry2Aa did not compete with CrylAc for binding and so could be used in transgenic cotton in combination with CrylAc to control H. armigera and manage resistance. Variation in the susceptibilities of three different H. armigera strains to CrylAc correlated with the parameter Bmax/Kcom.

In our changing health care system, the role of registered nurses (RNs) has become indistinguishable from other nursing and health care providers’ roles. The purpose of this research was to explore the perspectives of nurse leaders and direct care RNs about the existing and future RN scope of practice. This research used an interpretive description analysis on data that was garnered from nurse leaders and RNs through separate focus groups. Participants identified existing threats to their roles, examined their scope of practice and proposed changes to the RN scope of practice. Specific areas that were identified included leadership, advocacy and expansion of RNs practices were dominant themes.

Objective： To evaluate the effect of chitosan （CH） and hydrogen peroxide （H2O） seed coatings and seedling sprinklings on two different maize varieties by measuring their phenology, the H202 presence, the catalase （CAT） activity, and the protein quantity. Methods： Seven groups of ten seeds for each maize variety were treated with CH （2% （20 g/L） and 0.2% （2 g/L）） or H2O2 （8 mmol/L） by coating, sprinkling, or both. Germination and seedling growth were measured. One month after germination, the presence of H202 in seedlings in the coated seed treatments was evaluated. Protein content and CAT activity were determined under all treatments. Results： H2O2 seed coating en- hanced the germination rate and increased seedling and stem length in the quality protein maize （QPM） variety. Seedlings had a higher emergence velocity under this treatment in both varieties. CH and H2O2 sprinklings did not have an effect on seedling phenology. Exogenous application of H2O2 promoted an increase of endogenousH2O2. OH and H2O2seedling sprinkling increased the protein content in both maize varieties, while there was no significant effect on the CAT activity of treated seeds and seedlings. Conclusions： CH and H2O2 enhance some phenological and biochemical features of maize depending on their method of application.
