Organic acids and their derivatives like butyl stearate have recently shown antisickling activity. Some none aromatic esters were synthetized and tested for their antisickling activity using Emmel test. On 21 esters tested only three showed no antisickling activity. Butyl palmitate, propyl palmitate, butyl stearate, propyl stearate and methyl nonadecanoate showed interesting antisickling activity with a normalization rate higher than 70%.

The corrosion inhibition effect of Sulfacetamide and sotalol on the mild steel has been investigated in 1M H3PO4 acid medium. The inhibiting effect was investigating using weight loss measurement and quantum chemical method. The obtained results revealed that both inhibitors inhibited the mild steel corrosion in the phosphoric acid solution. The inhibitors showed more than 90% inhibition efficiency at optimum concentration. Sulfacetamide shows inhibition efficiency of 94.22 whereas sotalol shows efficiency of 91.40 at optimum concentration. Results obtained exposed that inhibition occurs through adsorption of the drugs on mild steel surface without modifying the mechanism of corrosion process obeying the Langmuir adsorption isotherm. Density functional theory (DFT) has been used to determine the relationship between molecular configuration and their inhibition efficiencies. The order of inhibition performance obtained from experimental results is successfully verified by DFT. Scanning electron microscopy (SEM) studies of the mild steel surfaces established the presence of a protective adsorbed film.

Aims: The purpose of this research was to perform the physical and chemical study of the composition and the quality of the fillet of Hoplias malabaricus (Traira) and Leporinus friderici (Bloch, 1794) collected in Pirativa River-Santana-Ap. Study Design: This study was chosen in the areas on the banks of Pirativa river in anthropized and non-anthropized areas in the city of Sao Raimundo, at coordinates N 00 02'08,9 "W 051 15 '32.3" in Santana-AP. Place and Duration of Study: the research was conducted in Pharmacognosy and Phytochemical Laboratory of the Course of Pharmacy from January to September of 2014, and in the Fish Processing Laboratory of the Federal University of Amapa (UNIFAP), from July to September of 2014.
