This qualitative study aimed to determine the perceived barriers of different community stakeholders' to providing resources for improving food security in households with young children in the U.S. Community stakeholders working with low-income families with children 0-3 years of age in Florida were recruited to represent healthcare ( = 7), community/policy development ( = 6), emergency food assistance ( = 6), early childhood education ( = 7), and nutrition education ( = 6) sectors. In 2020, one-on-one interviews were conducted with each stakeholder in via Zoom, using an interview script based on the PRECEDE-PROCEED model and questions to capture the impacts of COVID-19. The interviews were audio-recorded, transcribed verbatim, and analyzed using a deductive thematic approach. A cross-tab qualitative analysis was used to compare data across categories of stakeholders. Healthcare professionals and nutrition educators indicated stigma, community/policy development stakeholders indicated a lack of time, emergency food assistance personnel indicated a limited access to food, and early childhood professionals indicated a lack of transportation as the main barriers to food security prior to COVID-19. COVID-19 impacts included the fear of virus exposure, new restrictions, lack of volunteers, and a lack of interest in virtual programming as barriers to food security. As perceived barriers may vary with respect to providing resources to improve food security in families with young children and the COVID-19 impacts persist, coordinated policy, systems, and environmental changes are needed.

Urban environments are thought to improve food security, by offering enhanced access to markets and income opportunities. Yet this idea is hard to test empirically due to an abundance of confounding factors and selection issues. This study leverages a resettlement program in China to provide the first quasi-experimental estimate of city life on food consumption and nutrition among low-income households.

Ovalbumin (OVA) is a high-risk allergen with complex tertiary structure in food samples. Here, we developed an accurate UPLC-MS/MS-based assay to improve OVA quantitative performance in processed foods. Full-length isotope-labeled OVA proteins (OVA-I) were synthesized using stable isotope labeling by amino acids in cell culture (SILAC) technique and employed as functional internal standards to ensure similar cleavage sites between internal standards and analytes.

An agrivoltaic system (AVS), wherein crops and electricity are simultaneously produced on the same agricultural land, contributes to renewable energy production and food security. AVS is expected to expand energy production in rural areas; however, its energy balance has not been comprehensively investigated. In this study, the energy balance of an AVS established in 2021 in the paddy fields on Shonai Plain was determined.

Plant diseases constantly threaten crops and food systems, while global connectivity further increases the risks of spreading existing and exotic pathogens. Here, we first explore how an integrative approach involving plant pathway knowledgegraphs, differential gene expression data, and biochemical data informing Raman spectroscopy could be used to detect plant pathways responding to pathogen attacks.

Microplastic pollution seriously affects global agroecosystems, strongly influencing soil processes and crop growth. Microplastics impact could be size-dependent, yet relevant field experiments are scarce. We conducted a field experiment in a soil-maize agroecosystem to assess interactions between microplastic types and sizes.
