Few studies have been carried out on the effects of ligands on rare earth element (REE) bioaccumulation processes. In this study, the effects of phosphate (Pi, an inorganic ligand) and citrate (an organic ligand) on accumulation and fractionation of REEs in wheat were investigated using aqueous culture with extranous mixed REEs (MRE). The results show that initial Pi solution culture at various le...... hiện toàn bộ
Copper Exposure Induced Chicken Hepatotoxicity: Involvement of Ferroptosis Mediated by Lipid Peroxidation, Ferritinophagy, and Inhibition of FSP1-CoQ10 and Nrf2/SLC7A11/GPX4 AxisBiological Trace Element Research - - Trang 1-11 - 2023

Copper (Cu) is one of the most significant trace elements in the body, but it is also a widespread environmental toxicant health. Ferroptosis is a newly identified programmed cell death, which involves various heavy metal–induced organ toxicity. Nevertheless, the role of ferroptosis in Cu-induced hepatotoxicity remains poorly understood. In this study, we found that 330 mg/kg Cu could disrupt the ...... hiện toàn bộ

Mn2+ stimulated change of Mg-ATPase activity has been found in the synaptic fraction of rat brain that was named Mn-ATPase. Investigation of the molecular mechanism has shown that Mn-ATPase is a multi-sited enzyme system whose minimum functional unit is a dimer. Its substrate is the MgATP complex. The number of sites for Mn2+ as for essential activators and that of full-effect inhibitors are equal...... hiện toàn bộ
Study of the oxidative metabolic function and chemotaxis of neutrophils from patients with cancer influenced by Selenium YeastBiological Trace Element Research - Tập 25 - Trang 201-209 - 1990
Huibi Xu, Weide Mei, Zhaoming Dong, Baoliang Liao
The effects of Selenium Yeast (SY) given orally to patients with cancer on the oxidative metabolic function and chemotaxis of neutrophils were studied by Lumino-dependent Chemiluminescence (CL) assay and agarose plates assay, respectively. The results showed that the background CL and the peak value CL of neutrophils from patients with cancer 14 d after taking SY were, on the average, 4 and 1.2 ti...... hiện toàn bộ
Rapid and Facile Microwave-Assisted Synthesis of Palladium Nanoparticles and Evaluation of Their Antioxidant Properties and Cytotoxic Effects Against Fibroblast-Like (HSkMC) and Human Lung Carcinoma (A549) Cell LinesBiological Trace Element Research - Tập 197 - Trang 132-140 - 2019

We report here a simple microwave irradiation method (850 W, 3 min) for the synthesis of palladium nanoparticles (Pd NPs) using ascorbic acid (as reducing agent) and sodium alginate (as stabilizer agent). The synthesized nanoparticles were characterized using transmission electron microscopy (TEM), energy dispersive X-ray (EDX), X-ray diffraction spectroscopy (XRD), UV-Visible spectroscopy, and Fo...... hiện toàn bộ
