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 ...
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 ...
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 ...
Climate change in layer poultry farming: Impact of heat waves in region of Bastos, Brazil
(Revista Brasileira de Ciencia Avicola, 2018-10-01) [Artigo]
The region around the municipality of Bastos, state of São Paulo, accounted for about 7% of Brazilian egg production in 2015. In 2012, it experienced a heat wave that resulted in the death of approximately 500,000 hens, ...
Enzymatic antioxidants-Relevant or not to protect the photosynthetic system against cadmium-induced stress in Massai grass supplied with sulfur?
(Environmental And Experimental Botany, 2018-11-01) [Artigo]
Exposure to cadmium (Cd) can cause oxidative stress and injuries to the photosynthetic apparatus of plants. Otherwise, plant metabolism impaired by Cd toxicity can be aided by a proper sulfur (S) nutrition, since S is a ...
