Introduction Neodymium (Nd), a rare earth element (REEs), is widely utilized in industry. Although the detailed biological role of Nd plant biology unclear, recent reports have noted its oxidative phytotoxicity at concentrations higher than 200 mg kg -1 soil. At present it unclear if these detrimental effects could be offset by global rise atmospheric carbon dioxide concentration ([CO 2 ]) which has been shown to enhance photosynthesis and growth wide range C3 species. Methods To assess any...

The effects of glucagon injection and infusion glucose volatile fatty acids were studied in one-humped camels. Twenty adult male camels divided into four equal groups. first group was infused with physiological saline served as a control. second injected single dose glucagon, the third (50%) sterile saline, fourth acid (VFA) mixture. In first, groups, sampling performed before beginning infusions (control time), at 15, 30, 60 120 min post-infusion. Plasma concentrations monitored 5, 10, 20,...

The extensive and uncontrolled utilization of rare earth elements, like europium (Eu), could lead to their accumulation in soils biota. Herein, we investigated the impact Eu on growth, photosynthesis, redox homeostasis barley how that be affected by future CO2 climate (eCO2). plants were exposed 1.09 mmol Eu3+/kg soil under either ambient (420 ppm, aCO2) or eCO2 (620 ppm). application induced its plant shoots caused significant reductions biomass- photosynthesis-related parameters, i.e.,...
