The presence of an endophytic fungus, Acremonium coenophialum, in tall fescue (Festuca arundinacea) deterred aphid feeding by Rhopalosiphum padi and Schizaphis graminum. Both species of aphid were unable to survive when confined to endophyte-infected tall fescue plants. Feeding deterrents and toxic factors to R. padi and Oncopeltus fasciatus, large milkweed bug, were primarily associated with a...

The objective of this study was to determine whether differences in toxicity between Tall larkspur (Delphinium barbeyi) and Duncecap larkspur (D. occidentale) were genetically inherent within the species, or due to environmental influences unique to the different regions where they grow. There was no difference in the concentration of the toxic alkaloids between the two species when grown in co...

In the part of the Loire River recently colonized by Eurasian beavers, we compared habitat characteristics among sites with lodges, sites with cut trees and sites without beaver. The absence of sandbank and canopy cover (by 10-15-m tall trees, by tall Salicaceae, and by bushy Salicaceae) appeared as good predictors for lodge settling. Based on this model, the number of proper lodge sites was es...

INTRODUCTION Chin cup (CC) therapy has been used as the traditional appliance for treating class III malocclusion during mixed dentition period. The aim of this study was to investigate the effect of CC on the improvement of skeletal and dentoalveo-lar skeletal changes in class III patients during mixed dentition stage. MATERIALS AND METHODS A total of 30 patients (7-9 years old) with skeleta...

The African-American community has been disproportionately burdened by diabetes and its associated complications. Nearly 2.8 million African Americans have diabetes. It is essential to increase community participation in diabetes prevention and health promotion as a method to improve health disparities. To address these issues, the Center for Medical Treatment Programs in Diverse Populations (M...
