Space food systems have evolved from tubes and cubes to Earth-like food being planned for the International Space Station. The weight, volume, and oxygen-enriched atmosphere constraints of earlier spacecraft severely limited the type of food that could be used. Food systems improved as spacecraft conditions became more habitable. Space food systems have traditionally been based upon the water supply. This presentation summarizes the food development activities from Mercury through Shuttle, Shuttle/Mir, and plans for the International Space Station. Food development lessons learned from the long-duration missions with astronauts on the Mir station are also discussed. Nutritional requirements for long-duration missions in microgravity and problems associated with meeting these requirements for Mir will be elucidated. The psychological importance of food and the implications for food development activities are summarized.

Introduction: When implemented by national and regional regulatory agencies good review practices (GRevPs) support the timely high-quality review of medicines for enhanced patients' availability to safe, quality and efficacious innovative and generic products. It is important that all aspects of GRevPs are continuously evaluated and updated to promote the continuous improvement of regulatory systems at national and regional levels. The aim of this study was to assess and compare the GRevPs of the national medicines regulatory agencies (NMRAs) of Burkina Faso, Cote d'Ivoire, Ghana, Nigeria, Senegal, Sierra Leone and Togo, who are active participants of the ECOWASMRH initiative to identify opportunities for improvement.

Background And Aims: Infertility, as defined by the World Health Organization, is the inability to conceive after 12 months of regular, unprotected intercourse. This study aimed to identify factors influencing infertility by applying data mining techniques, specifically rule-mining methods, to analyze diverse patient data and uncover relevant insights. This approach involves a thorough analysis of patients' clinical characteristics, dietary habits, and overall conditions to identify complex patterns and relationships that may contribute to infertility.

Spectrophotometer method, ELISA, and High-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) method have been widely used to quantify and characterize the glucose released from rice after in vitro digestion. Despite this, the results of the three methods may not be comparable. This work investigated the limitation of detection (LOD) and quantification (LOQ) of the glucose released after in vitro rice digestion.

Novel and emerging pathogens, enduring contamination, antibiotic resistance, an environment that is always changing, and the complexity of food production systems all contribute to the worsening of foodborne illness. It has been proposed that bacteriophages can serve as both fast food-borne pathogen detection tools and natural food preservatives in a variety of foods. Phages, like many other antimicrobial interventions used in food production systems, are not a cure-all for issues related to food safety, though.

Context: There are urgent calls to transition society to more sustainable trajectories, at scales ranging from local to global. Landscape sustainability (LS), or the capacity for landscapes to provide equitable access to ecosystem services essential for human wellbeing for both current and future generations, provides an operational approach to monitor these transitions. However, the complexity of landscapes complicates how and what to consider when assessing LS.
