A multifaceted tomotherapy quality assurance procedure has been developed. This procedure tests most of the features inherent in the tomotherapy Hi-Art device. This includes the megavoltage imaging quality, spatial and temporal accuracy of the dynamic delivery properties, as well as more traditional beam output characteristics. This is accomplished with a specialized multichannel electrometer that measures collected charge every 100 ms and a Virtual Water cylindrical phantom that holds many ion chambers and differing density insert plugs. Both devices are offered with the Hi-Art product. These tests are presented as well as their sensitivity to beam and delivery variations.

Host response to environmental exposures such as pathogens and chemicals can include modifications to the epigenome and transcriptome. Improved signature discovery, including the identification of the agent and timing of exposure, has been enabled by advancements in assaying techniques to detect RNA expression, DNA base modifications, histone modifications, and chromatin accessibility. The interrogation of the epigenome and transcriptome cascade requires analyzing disparate datasets from multiple assay types, often at single-cell resolution, derived from the same biospecimen.

Alive & Thrive has been a major global nutrition initiative that aimed to learn how to improve maternal, infant, young child, and adolescent nutrition and health on a large scale. During 2009-2014, Alive & Thrive developed and implemented interventions to improve infant and young child feeding at scale in three countries. Subsequently, Alive & Thrive expanded its work to more than 15 geographies, including six country-specific and two regional programs, to additionally address maternal and adolescent nutrition while adding agriculture and social protection programs to improve maternal, infant, and young child nutrition.
