Selenium-biofortified wheat can substantially improve human nutrition, by reducing selenium deficiency in humans. In this study, field trials were conducted to investigate the biofortification of (Se) and also assess influence foliar application Se (as sodium selenate) on metabolism carbohydrates, nitrogen contents, antioxidant system plants. Selenium was applied via sprays at following doses: 0, 12, 21, 38, 68, 120 g ha−1. The dose ha−1 provided highest concentrations grains biomass...
ABSTRACT Selenium (Se) is an important element that was discovered in 1817, and since the 1960s, it has been regarded as essential micronutrient for both animals humans, playing among other functions a relevant role antioxidant system of mammals. Inadequate blood Se levels human body well-known concern many parts world. This malnutrition problem often due to Se-poor diet, probably result low availability soils where crops are growing. Nowadays, known not only total content, but also...
The Fe (oxyhydr)oxide rind, or plaque, that forms on aquatic plant roots is an important sorbent of metal(loid)s and plays a role in the attenuation metal(loid) uptake into higher plants. However, mineral composition plaque thus its potential to sorb affected by solution chemistry. predominant strategy characterize using dithionite-citrate-bicarbonate (DCB) extraction elemental analysis reveals total quantity but misses structure (oxyhydr)oxide. Here, we developed new technique gentle...
Rare earth elements (REY) are the lanthanide (Z = 57–71), which have an ever-growing occurrence in present-day industries, agriculture, and modern life. Consequently, environmental concentrations expected to increase accordingly as a result of intensified utilization. Soils important sink for REY, yet little research has been conducted concerning activity, inputs, lability soil systems. This study evaluated REY (lanthanides + yttrium) sorption partition coefficients (Kd) two broadly...
Recentemente o emprego de medicamentos como Ozempic® e Mounjaro® off labelpara perda peso passa por exponencial crescimento. Tal aspecto fomenta grande preocupação a respeito da relação entre seu uso efeitos adversos que comprometam cavidade oral. O objetivo desta revisão integrativa foi sintetizar analisar literatura científica existente para identificar, descrever avaliar os colaterais orais associados ao Ozempic®, outros emagrecedores, visando compreender prevalência, implicações clínicas...
Water deficit inhibits plant growth by affecting several physiological processes, which leads to the overproduction of reactive oxygen species (ROS) that may cause oxidative stress. In this regard, iodine (I) is already known possibly enhance antioxidant defense system plants and promote photosynthetic improvements under adverse conditions. However, its direct effect on water responses has not yet been demonstrated. To verify efficiency I concerning tolerance deficit, we exposed soybean...
Selenium uptake and its content in soybean grains are affected by Se application methods. This study evaluated the impact of foliar combined with a multi-nutrient fertilizer (MNF) on soybean, establishing threshold to better understand relationship between yield two genotypes (58I60 Lança M5917). Two trials were conducted 4 × 2 factorial design: four rates (0, 10, 40, 80 g ha-1) methods (Se or not MNF). Foliar fertilizers applied twice, at phenological stages beginning pod development grain...
Agronomic biofortification with selenium (Se) maybe employed to improve the nutritional value of food crops while increasing plant’s tolerance water deficit conditions. Although not essential for plants, Se may increase plant stress by boosting plants’ defence system activity. This study aimed enrich common bean grains and alleviate effects on applying plants growing under greenhouse. Selenium was applied soil at 0, 0.25, 0.5, 1.0, 2.0 mg kg–1, irrigated water-deficit Antioxidant enzyme...
In the Brazilian Cerrado biome, there are wetlands locally known as "Veredas", which swampy plains between hills and rivers. Since 1970's, biome has been gradually converted to livestock, crop, or forestry production. Until now, very few studies were conducted evaluate baseline contents of trace elements in wetland soils. Due their position landscape (bottom lands), potentially susceptible contamination by runoff and/or leaching from surrounding areas at higher altitudes. This work evaluated...
Soybean is a major crop in Brazil and usually grown oxidic soils that need high rates of phosphate (P) fertilizers. also very suitable for biofortification with Se, since its grains have protein contents are widely consumed worldwide (directly or indirectly). Few studies addressed Se application under field conditions soybean biofortification, especially tropical soils. Here, we evaluated agronomic physiological responses resulting from different strategies biofortifying by applying this...
