Dissecting the mechanism of action of actinoporins. Role of the N-terminal amphipathic alpha-helix in membrane binding and pore activity of sticholysins I and II
(Plos One, 2018-08-30) [Artigo]
Actinoporins sticholysin I and sticholysin II (St I, St II) are proposed to lyse model and biomembranes via toroidal pore formation by their N-terminal domain. Based on the hypothesis that peptide fragments can reproduce ...
Determination of zinc in rice grains using DTZ staining and ImageJ software
(Journal Of Cereal Science, 2016-03-01) [Artigo]
Dithizone (DTZ) staining is a rapid, simple, and inexpensive method that allows the histochemical localization of Zn. In this study, we evaluated genotypic variation in Zn concentration in brown rice grown in the field ...
Natural variation of selenium in Brazil nuts and soils from the Amazon region
(Chemosphere, 2017-12-01) [Artigo]
Brazil nut tree (Bertholletia excelsa) is native of the Amazon rainforest. Brazil nuts are consumed worldwide and are known as the richest food source of selenium (Se). Yet, the reasoning for such Se contents is not well ...
Sample preparation combined with electroanalysis to improve simultaneous determination of antibiotics in animal derived food samples
(Food Chemistry, 2018-06-01) [Artigo]
A procedure based on liquid–liquid extraction (LLE) and phase separation using magnetically stirred salt-induced high-temperature liquid-liquid extraction (PS-MSSI-HT-LLE) was developed to extract and pre-concentrate ...
EFFECT OF TRANSPORTATION DISTANCE ON WEIGHT LOSSES IN PIGS FROM DEHYDRATION
(Engenharia Agricola, 2016-10-01) [Artigo]
The increasing of global demand for food has required more efficiency in the production process. Transportation represents a source of body dehydration for pigs transported from farm to slaughterhouses. This study aimed ...
Hidden Nickel Deficiency? Nickel Fertilization via Soil Improves Nitrogen Metabolism and Grain Yield in Soybean Genotypes
(Frontiers In Plant Science, 2018-05-08) [Artigo]
Nickel (Ni)-a component of urease and hydrogenase-was the latest nutrient to be recognized as an essential element for plants. However, to date there are no records of Ni deficiency for annual species cultivated under field ...
Magnetic nanocomposites (SR/IRON) type isotropic MRE directed to vibration absorption systems
(2017 Ieee 17th International Conference On Nanotechnology (ieee-nano), 2017-01-01) [Trabalho apresentado em evento]
In recent decades, an increasing effort has been made not only to foster cost-effective, competitive and innovative industries but also to create smart materials. In this work, we present the morphological, magnetic and ...
Wheat biofortification: Genotypic variation and selenium fertilization in Brazil
(Global Advances In Selenium Research From Theory To Application, 2016-01-01) [Trabalho apresentado em evento]
Selenium restricts cadmium uptake and improve micronutrients and proline concentration in tomato fruits
(Biocatalysis and Agricultural Biotechnology, 2019-03-01) [Artigo]
In order to identify the beneficial effects of Selenium (Se) in tomato (Solanum lycopersicum), genotypes MT and hp1, under Cadmium (Cd) toxicity, the following analyses were performed: Cd and Se concentration and translocation ...
Influence of the Gas Pressure of Plasma Nitriding on the Structural, Mechanical and Tribological Surface Properties of AISI 316L
(Materials Research-ibero-american Journal Of Materials, 2019-01-01) [Artigo]
In this paper, the influence of gas nitriding (80% H-2-20% N-2) pressure (between 3 and 7 Torr) on the modification of surface properties of AISI 316L stainless steel is examined. The structural, mechanical, tribological ...
