Effect of Selenium Supplementation via Brazil Nut (bertholletia Excelsa, Hbk) on Thyroid Hormones Levels in Hemodialysis Patients: a Pilot Study.
BACKGROUND thyroid function depends on trace mineral selenium (Se), being at the active center of the iodothyronine deiodinase that catalyzes the conversion of the thyroxine (T4) to the active form of thyroid hormone, triiodothyronine (T3). Hemodialysis (HD) patients have reduced T3 levels partly due to impaired hormonal conversion that can be related to Se deficiency, a common feature in these...
متن کاملSelenium and Aflatoxins in Brazil Nuts
Brazil nuts (Bertholletia excelsa H.B.K.) are considered a high nutritious food. Apart from carbohydrates, lipids, sulphur proteins and minerals, Brazil nuts are known to be rich in selenium Se (Barclay et al., 1995; Coutinho et al., 2002, Souza et al., 2004, Pacheco and Scussel, 2007). Despite of that, when their shell are cracked either when pods fall on the ground, or during pod opening for ...
متن کاملDiversity and genetic structure of the native Brazil nut tree (Bertholletia excelsa Bonpl.) population.
The present study was carried out in a native Brazil nut tree population (Bertholletia excelsa Bonpl., Lecythidaceae) to assess its genetic diversity and structure. Ten microsatellite markers were used to genotype 198 adult trees (B. excelsa). The population presented high genetic diversity and inbreeding absence rates. The empirical Bayesian method showed three distinct groups in the structure...
متن کاملDetailed Study of Brazil Nut ( Bertholletia excelsa ) Oil Micro - Compounds : Phospholipids , Tocopherols and Sterols
O óleo da castanha-do-pará (Bertholletia excelsa) foi estudado por causa da sua composição em ácidos graxos, tocoferóis, esteróis e fosfolipídios. A composição de ácidos graxos nos fosfolipídeos também foi estudada. Os resultados foram comparados com os do girassol, da castanha, amêndoa, noz, soja e azeites. O seu alto teor em ácidos graxos insaturados, em b-tocoferol e em b-sitosterol confere ...
متن کاملPurification and biochemical characterization of Brazil nut (Bertholletia excelsa L.) seed storage proteins.
Brazil nut storage proteins, 2S albumin, 7S vicilin, and an 11S legumin, were purified using column chromatography. Analytical ultracentrifugation of the purified albumin, vicilin, and legumin proteins, respectively, registered sedimentation coefficients of 1.8, 7.1, and 11.8 S. Under reducing conditions, the major polypeptide bands in 2S albumin were observed at 6.4, 10-11, and 15.2 kDa. The 7...
