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 ...
Fertirrigation for vegetables grown in greenhouses
(Journal of Biosystems Engineering, 2014) [Artigo]
Purpose: Concerns over the quantity of available freshwater for agriculture have triggered the development of technologies intended to increase efficiency of water use, especially with regard to irrigation. A new technique ...
Characterization of heat waves affecting mortality rates of broilers between 29 days and market age
(Revista Brasileira de Ciência Avícola, 2010-12-01) [Artigo]
Climate may affect broiler production, especially where there are heat waves, which may cause high mortality rates due to the heat stress. Heat wave prediction and characterization may allow early mitigation actions to be ...
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
