13. Assessing the Content of Micronutrients in Soils and Sugarcane in Different Pedogeological Contexts of Northeastern Brazil
ABSTRACT Micronutrient research for sugarcane in northeastern Brazil is scarce and most works on this issue date back to the 70’s and 80’s. The objectives of this study were to assess the available and reserve pools of Fe, Mn, Cu, and Zn in soils cultivated with sugarcane under three geological contexts in northeastern Brazil as well as to diagnose the m

14. Effects of nickel fertilization on soybean growth in tropical soils
ABSTRACT Although nickel (Ni) is recognized as plant nutrient since the turn of the 21st century, uncertainty remains about its optimum application rates and forms. This paper focuses on Ni application in soils, relating to its effect as a plant micronutrient. Specifically, the effect of Ni on the activity of urease in soybean plants is examined. The effects

15. Are there differences in nutrient intake of Brazilian adults according to weight status?
Resumo Avaliou-se a ingestão e a prevalência de ingestão inadequada de nutrientes segundo a condição de peso em adultos brasileiros de áreas urbanas (n = 16.198) investigados no Inquérito Nacional de Alimentação (INA 2008-2009), que obteve o registro alimentar de dois dias não consecutivos. A prevalência de inadequação da ingestão de nutrientes

16. Does planting time affect the nutritional demand and yield of potato cultivars?
RESUMO: Determinar a absorção de nutrientes na cultura da batata em diferentes estágios de desenvolvimento é importante pois permite identificar os tempos em que os elementos são mais exigidos pelas plantas. O objetivo deste trabalho foi avaliar a absorção de nutrientes em cultivares de batata em resposta a diferentes épocas de plantio. O experiment

17. Concentration and accumulation of micronutrients in robust coffee
ABSTRACT. Knowledge on the dynamics of micronutrients in coffee tree assists nutritional diagnosis and fertilization management. Therefore, the objective of this study was to evaluate the concentration and accumulation of micronutrients in the leaves and fruits of Coffea canephora. The experiment was managed in crops propagated for 2.5 years in a split-plot-

18. Hampered Vitamin B12 Metabolism in Gaucher Disease?
Abstract Untreated vitamin B12 deficiency manifests clinically with hematological abnormalities and combined degeneration of the spinal cord and polyneuropathy and biochemically with elevated homocysteine (Hcy) and methylmalonic acid (MMA). Vitamin B12 metabolism involves various cellular compartments including the lysosome, and a disruption in the lysosomal

19. Reference Values of Grain Nutrient Content and Removal for Corn
ABSTRACT: Unchanged reference values of grain nutrient contents for corn have been used for over 20 years, despite yield increases, the development of new hybrids, and modifications to cropping systems, especially the establishment of in-season second crops and the wide adoption of no-tillage. This study measured macro- and micronutrient contents in corn gra

20. Micronutrients: Speculation on Inborn Errors, Nutrigenomics, Evolution, the Microbiome, and Nutritional Immunity
Abstract Many micronutrients or cofactors derived from micronutrients are highly reactive, hence their role in catalysis of reactions by enzymes. The concentration of cofactors has to be kept low to avoid unwanted reactions while allowing them to bind to the (apo)enzymes that need them. A new disorder causing B6-responsive epilepsy (proline synthetase cotran

22. Rhizobial Inoculation and Molybdenum Fertilization in Peanut Crops Grown in a No Tillage System After 20 Years of Pasture
ABSTRACT: Peanut (Arachis hypogea) is an important legume grain consumed by humans and utilized for effective nutrient cycling in a diverse cropping system. Areas that have been cultivated with perennial pasture for decades may have nutritional deficiencies and lack a sufficient population of atmospheric nitrogen-fixing bacteria. Molybdenum is an essential m

23. Dietary intake of non-dialysis chronic kidney disease patients: the PROGREDIR study. A cross-sectional study
ABSTRACT BACKGROUND: Despite evidence that diet is very important in relation to chronic kidney disease (CKD) progression, studies in this field are scarce and have focused only on some specific nutrients. We evaluated the energy, macronutrient and micronutrient intakes and dietary patterns of non-dialysis CKD participants in the PROGREDIR study. DESIGN A

24. The role of selenium in insulin resistance
ABSTRACT In recent years, there has been growing interest in clarifying the pathogenesis of some chronic diseases, such as obesity and type 2 diabetes mellitus. Metabolic alterations in these diseases are characterized by chronic hyperglycemia and insulin resistance. Studies have demonstrated the participation of minerals in the pathogenesis of insulin resis
