Effect of spray-drying with organic solvents on the encapsulation, release and stability of fish oil (Elsevier, 2018-10-15)Fish-oil (FO) was encapsulated with hydroxypropylcelullose (HPC) by conventional spray-drying with water (FO-water) and solvent spray-drying with ethanol (FO-EtOH), methanol (FO-MeOH) and acetone (FO-Acet) in order to study ...
-
(1988)The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
-
(MDPI, 2021)Commercialization of extra virgin olive oil (EVOO) requires a best before date recommended at up to 24 months after bottling, stored under specific conditions. Thus, it is expected that the product retains its chemical ...
-
(Stockton Press, 1990-01)The ability of the lignino-cellulolytic actinomycete Streptomycetes viridosporus T7A to attack purified fractions of kraft lignin was examined. In the presence of 0.3% yeast extract, high-molecular weight kraft lignin (MW ...
-
(Elsevier, 2017)The aim of the present work was to prepare tadalafil (TDF) nanocrystals-loaded oral polymeric films (OFs) and investigate the effect of hydrophilic surfactants and drug loads on the physico-mechanical and dissolution ...
-
(2013)Salmones coho (Oncorhynchus kisutch) fueron alimentados con una dieta enriquecida en antioxidantes sintéticos (butil-hidroxi-tolueno y etoxiquina, dieta I) y su efecto comparado con dos dietas enriquecidas en antioxidantes ...
-
(Society of Chemical Industry, 2015)BACKGROUND: Great attention has been paid to the antioxidants present in farmed fish feeds, with the replacement of synthetic antioxidants by natural ones being a main objective. In the present study, Coho salmon (Oncorhynchus ...
-
(Elsevier, 2018)The effect of the composition of twelve varieties of extra virgin olive oils (EVOOs) on their differentiation based in agronomic criteria and on the antioxidant capacity was studied. Principal component analysis permitted ...
-
(2012)The electrochemical response of a glassy carbon electrode modified with carbon nanotubes (CNT) dispersed in two solvents, water and DMF, and two polymers, chitosan and Nafion is reported. The films were homogeneous when ...
-
(Royal Society of Chemistry, 2019)In this paper, we assess the performance of 24 density functional theory (DFT) based methods classified into 5 categories (GGA, MGGA, HGGA, HMGGA and DHGGA) in predicting reaction energetics, transition state geometries, ...
-
(Wiley-VCH Verlag, 2014)Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major health problem worldwide. In this work, we report the development of palladium and platinum metal complexes with 5-nitrofuryl-containing ...
-
(Elsevier, 2016)Graphene materials often are obtained through thermal reduction of graphite oxide. This is due to the fact that other synthesis methods are more difficult and generally render lower yield. The structure and morphology of ...
-
(AMER CHEMICAL SOC, 2006-04-10)Three structures of novel cluster carboxylates of molybdenum(II) (la-c) and copper(II) (2) with the OOC-CCHCo2(CO)(6) ligand are presented. The solvent topology plays an important role in the formation of the crystal lattice ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2002-09)Kraft bleached cellulose from Pinus radiata was submitted to methylation reactions in heterogeneous media. After activation with 29% (w/w) NaOH solution, methylation reactions were carried out both with dimethyl sulfate ...
-
(2009)Periodic density functional theory calculations on large supercells have been carried out to investigate the atomic and electronic structure of small gold particles (Au2, Au4, Au9, Au13, and Au14) supported on the (001) ...
-
(DUSTRI-VERLAG DR KARL FEISTLE, 2000-06)Background: Food-induced changes on the bioavailability of a sustained release lithium carbonate matrix tablet, which uses an acrylic matrix of Eudragit RSPM as sustaining agent, have been studied in healthy male volunteers. ...
-
(2004)The high temperature antioxidant efficiency of α-tocopherol, α-tocotrienol and a mixture of both on hazelnut oil were evaluated. Crude hazelnut oil (HZO), crude hazelnut oil treated with alumina (THZO), as well as three ...
-
(2007)The antioxidant effects of tocols (α-tocopherol and α-tocotrienol) and Rosa mosqueta shell extract added to antioxidant-stripped canola oil (TCO) were evaluated and compared with the non-stripped oil (CO) under the same ...
-
(American Chemical Society, 2020)Because of the growing demand for the use of photovoltaic cells to transform solar energy into electrical energy, radiation concentration systems such as luminescent solar concentrators (LSCs) have gained significant ...
-
(PORTLAND PRESS, 2002-09-15)The aim of the present study was to evaluate the capacity of synthetic L- and D-peptides encompassing the HIV-1(BRU) gp160 REKR cleavage site to interfere with HIV and simian immunodeficiency virus (SIV) replication and ...
