Abstract The aim of this work is to investigate the relationship between iron and oxidative stress in the immune organs of excessive iron-fed sheep. Sixteen German Mutton Merino rams were randomly divided into 4 groups, which were fed the basal diets supplemented with 50 (CON), 500 (L-iron), 1000 (M-iron), and 1500 (H-iron) mg Fe/kg as ferrous sulfate monohydrate (FeSO4·H2O), respectively. The actual iron content in the diet was determined to be 457.68 (CON), 816.42 (L-iron),...

Abstract Cadmium is extremely toxic heavy metal, and there is no specific, safe, and efficacious therapeutic management of cadmium toxicity. Scientific literature reveals several probiotic microorganisms which alleviate experimentally induced cadmium toxicity in animals. The present review attempts to collate the experimental studies on probiotics and probiotic-derived natural products with cadmium toxicity ameliorative effects. Literature survey revealed that seven (7) types...

Abstract Manganese (Mn) can have adverse effects on organisms as a result of heavy or chronic exposure, including neurological damage. This study examined the effects of chronic exposure to manganese chloride (MnCl2) on various biochemical indices of inflammatory cytokines, antioxidant enzymes, and heat shock proteins (HSPs) in the kidneys of Hy-line cocks. The exposures were carried out using 600, 900, or 1800 mg/kg doses of MnCl2 administered for periods of 30, 60, and 90 days....

Abstract A study of the seasonal dynamics of copper (Cu) deficiency and its effects on the antioxidant system in Wumeng semi-fine wool sheep in Weining county was conducted. In addition, the concentrations of mineral elements in soil, grass, and blood of affected and healthy Wumeng semi-fine wool sheep were determined, and blood indices were measured. The results showed that Cu contents in soil, grass, and sheep blood from the experimental pasture were significantly lower than...

Abstract Lung cancer (LC) is the number one cancer killer of women both in the USA and around the world. Besides cigarette smoking, an important feature in the etiology of LC is its strong association with exposure of toxic metals. The primary objective of the present investigation was to assess the concentrations of toxic/essential elements (Ni, Ca, Se, Zn, Co, K, Cr, As, Cu, Na, Fe, Hg, Cd, Mg, Mn, and Pb) in the serum samples of LC female patients with female controls by atomic...

Abstract Aluminum (Al) alters iron regulatory factors content and leads to the changes in iron-related proteins causing iron accumulation. But limited evidence ascertains this hypothesis. Therefore, our experiment was conducted and four groups of male Wistar rats were orally administrated of 0, 50, 150, and 450 mg/kg BW/d aluminum chloride (AlCl3) for 90 days by drinking water, respectively. The cognitive function, pathological lesion of hippocampus, oxidative stress, as well...

Abstract Iron deficiency is a leading cause of anemia. Amino acids are known to promote the absorption of both soluble and insoluble iron. The bioavailability of organic iron is higher than that of inorganic iron. Therefore, the aim of this study was to evaluate the iron absorption of glycine-bound iron (an organic iron) and a combination of glycine-bound iron and gamma aminobutyric acid (GABA) in mice with iron deficiency anemia (IDA). Mice were fed an iron-deficient diet for...

Abstract To improve the anticancer activity of telmisartan, its structure has been modified by Zn(II) complexation giving [Zn(Telm)2(H2O)2]·2H2O (ZnTelm). The cytotoxic effect was measured on the human lung cancer cells (A549) and on the lung fibroblast cells (MRC-5). The complex markedly improved anticancer activity (IC50 75 μM) of telmisartan (IC50 125 μM) or ZnSO4 (IC50 225 μM) and did not show toxicity on non-cancer cells, inducing oxidative stress with cellular ROS generation...

Abstract Iodine is an essential macronutrient for feto-maternal growth and development. Emerging evidence suggests that maternal iodine deficiency during pregnancy is potentially associated with both maternal and fetal adverse outcomes. The aim of this systematic review and meta-analysis was to investigate the association between maternal iodine status in euthyroid pregnant women and adverse pregnancy outcomes. A comprehensive literature search was performed in PubMed, Web of...

Abstract The role of zinc is known in balancing the oxidant/antioxidant system and also in improving insulin resistance in many diseases. Recently, in vivo and in vitro studies revealed roles of zinc on lipophagy and suppressing hepatic lipid deposition. The present study is the first double-blind randomized clinical trial that investigated the effect of zinc supplement on clinical manifestations and anthropometric parameters of overweight/obese non-alcoholic fatty liver patients...

Comparative iTRAQ Proteomics Reveals Multiple Effects of Selenium Yeast on Dairy Cows in Parturition
Abstract The effects of prepartum dietary supplementation with selenium yeast on low abundant plasma proteins in postpartum dairy cows are not known. In this study, 24 healthy parturient dairy cows were divided into two groups (group C, a control group, and group T, a selenium treatment group). Low abundance proteins were extracted from plasma samples of calving cows, and 542 proteins were identified by isobaric tags for relative and absolute quantitation (iTRAQ) proteomic analysis....

Abstract Selenium (Se) is one of the essential elements required to maintain human health. Although various kinds of Se supplements are now available on the market, their biological activities and toxicities vary based on the transportation characteristics of Se. In this study, we compared the absorption and distribution of Se in rats administered with different Se supplements: Se-enriched Bifidobacterium longum DD98 (Se-DD98), selenized yeast (Se-Y), and sodium selenite (Na2SeO3)....
