Coastal lagoons are vital yet vulnerable marine ecosystems. This study analyzes a five-year dataset to evaluate changes in water quality and their impacts on biota in Pinqing Lagoon (PQL). Seasonal surveys conducted from 2019 to 2023 across 14 sites revealed significant variability in water and sediment quality parameters.

Objective: To examine the association between childhood ADHD and lifestyle risk factors (physical inactivity and high fast-food consumption) from adolescence to early adulthood.

Methods: This retrospective cohort study used secondary data from Wave I to III of the National Longitudinal Study of Adolescent Health (Add Health) in a national representative sample of adolescents ( = 6,814). Multivariable Poisson regression and Generalized Estimating Equation were used to estimate adjusted relative risks (aRRs) and corresponding 95% confidence intervals (95% CIs), controlling for confounders.

Introduction: Many designathons, hackathons, and similar participatory events suffer from minimal training and support after the events. Responding to this need, we organized a health innovation bootcamp: an intensive, team-based apprenticeship training with research and entrepreneurial rigor among young people in Nigeria to develop HIV self-testing (HIVST) delivery strategies for Nigerian youth. The purpose of this paper was to describe an innovation bootcamp that aimed to develop HIVST delivery strategies for Nigerian youth.

Passion fruit is one of the most famous fruit crops in tropical and subtropical regions due to its high edible, medicinal, and ornamental value. Flavonoids, a class of plant secondary metabolites, have important health-related roles. In this study, a total of 151 flavonoid metabolites were identified, of which 25 key metabolites may be the main contributors to the purple phenotype.

Article Synopsis
  • Natural seawater electrolysis is a promising method for producing hydrogen, but it faces challenges with long-term instability due to chloride corrosion.
  • A new material, Zr doped CoO, shows strong performance, requiring a low overpotential of 570 mV and demonstrating minimal decay (0.78%) over 500 hours of operation.
  • A novel membrane electrode setup with a self-developed anion exchange membrane converts the produced hydrogen into ammonia for easier storage, while theoretical calculations reveal how Zr enhances the material's stability and protects it from chloride damage.
