The genetic variability of the efficiency of the first steps of sulfate utilization and its correlation with productivity were evaluated in nine maize hybrids. 35SO42- uptake by excised roots, uptake by intact plant roots, translocation to leaves, and ATP sulfurylase in leaves were taken into account. Uptake rate by roots of intact plants did not show any pulse within 7 to 12 days from emergence., in contrast with the previously observed behaviour of excised roots during root elongation. The uptake rate of intact plants was positively correlated with that of excised roots, hut the variability within the nine genotypes tested was less. Productivity was positively correlated with sulfate uptake by both intact plant and excised roots, the level of significance being higher in the first case.. Translocation to leaves and ATP sulfurylase activity were not correlated to productivity. Therefore, in the case of sulfate, the grain yield of commonly cultivated, maize hybrids appeared to be controlled more by the root uptake step than by the activation and translocation steps.

Background: Acrylamide, a component of fried foods, has been associated with several negative health outcomes. However, the relationship between dietary acrylamide and osteoporotic fractures has been explored by a few cross-sectional studies., Aims: To investigate if dietary acrylamide is associated with the onset of fractures in North American participants at high risk/having knee osteoarthritis (OA), over 8 years of follow-up., Methods: A Cox's regression analysis, adjusted for baseline confounders was run and the data were reported as hazard ratios (HRs) and 95% confidence intervals (CIs). Dietary acrylamide intake was assessed at the baseline using a food frequency questionnaire and categorized in tertiles (T), whilst fractures' history was recorded using self-reported information., Results: Altogether, 4,436 participants were included. Compared to participants with lower acrylamide intake (T1; < 3,313 μg), those with a higher acrylamide intake (T3; > 10,180 μg) reported a significantly higher risk of any fracture (HR = 1.37; 95% CI 1.12-1.68; p for trend = 0.009), forearm (HR = 1.73; 95% CI 1.09-2.77; p for trend = 0.04), spine (HR = 2.21; 95% CI 1.14-4.31; p for trend = 0.04), and hip fracture (HR = 4.09; 95% CI 1.29-12.96; p for trend = 0.046)., Conclusions: Our study is the first to report that high dietary acrylamide may be associated with an increased risk of osteoporotic fractures., (© 2022.
