Article Synopsis
  • Mercury is a toxic substance that accumulates in fish, particularly in its organic form, methylmercury (MeHg), which poses risks to human health through contaminated fish consumption.
  • Understanding how mercury accumulates in aquatic species requires analyzing several biokinetic parameters, including uptake rate, assimilation efficiency, and efflux rate, which were studied across 38 fish and 34 aquatic invertebrate species, yielding 502 total data points.
  • The study found that the form of mercury and various environmental factors like water type and organism weight significantly influenced these parameters, highlighting differences between fish and invertebrates, and challenging previous assumptions about the impact of environmental conditions on mercury accumulation in aquatic ecosystems.

Stomata respond slowly to changes in light when compared with photosynthesis, undermining plant water-use efficiency (WUE). We know much about stomatal mechanics, yet efforts to accelerate stomatal responsiveness have been limited despite the breadth of potential targets for manipulation. Here, we use mechanistic modeling to establish a hierarchy of putative targets affecting stomatal kinetics.

Background: There is extensive evidence that rapid infant weight gain increases the risk of childhood obesity, but this is normally based on childhood body mass index (BMI) only and whether or not this is because infants with rapid weight gain accrue greater fat mass is unknown.

Objective: The primary objective of our study was to test whether the proportion of infant weight gain due to concurrent increases in fat mass is greater in infants with rapid weight gain as compared to those with normal growth.

Methods: Body composition was assessed by (1) air-displacement plethysmography (ADP) at 0 and 6 months in 342 infants from Australia, India, and South Africa and (2) deuterium dilution (DD) at 3 and 24 months in 555 infants from Brazil, Pakistan, South Africa, and Sri Lanka.

Article Synopsis
  • - The study develops and validates the Sri Lankan Sports Nutrition Knowledge Questionnaire (SLn-SNKQ) specifically for track and field athletes, aiming to improve assessment of athletes' nutrition knowledge and its impact on their food choices.
  • - Validation involved expert input on content, athlete feedback for clarity, and testing with different professional and athlete groups to ensure the questionnaire effectively measures sports nutrition knowledge.
  • - The final SLn-SNKQ consists of 123 items across 32 questions, demonstrating strong validity and reliability, with significant differences in scores among groups of nutrition-trained and non-nutrition-trained individuals, and elite athletes.
