Diurnal variation in phloem sap composition has a strong influence on aphid performance. The sugar-rich phloem sap serves as the sole diet for aphids and a suite of physiological mechanisms and behaviors allow them to tolerate the high osmotic stress. Here, we tested the hypothesis that night-time feeding by aphids is a behavior that takes…[Read more]

Background Preschool child anthropometric status has been assessed nationally in Nepal since 1975, with semi-decadal surveys since 1996, plus several recent, short-interval surveys to track progress toward achieving a World Health Assembly (WHA) goal to reduce stunting to 24% by 2025. Objective We report prevalence of preschool child stunting and…[Read more]

Background Endobiliary radiofrequency ablation (EB-RFA) has emerged as a palliative treatment for malignant biliary strictures (MBSs); however, concerns about complications related to thermal injury remain. In this study, we evaluated the efficacy and safety of EB-RFA with a novel catheter for MBS. Methods Patients with inoperable cancer causing…[Read more]
