(Elsevier, 2008)The catalytic influence of Sulfolobus metallicus in the bioleaching of chalcopyrite at 70 degrees C and pH 1.5 was studied in shake flask experiments. Leaching was conducted in an iron-free basal medium with a -80 #+ 120 ...
-
(Wiley, 2017)Quercetin (Q) and epicatechin (E) microparticles were designed using an oil-insoluble polymer (inulin [In]) as encapsulating agent and with or without an oil-soluble polymer (soy protein isolate [SPI]) by spray-drying. ...
-
(2023)Selective neurotoxins have the ability to exert their neurotoxic effects in dopaminergic neurons. This could depend on their affinity to the dopamine transporter. The possible molecular mechanisms involved in dopamine and ...

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 ...
-
(Electrochemical Soc Inc, 2020)The present studies reveal superoxide radical anion reactivity against synthesized coumarins. Free radicals play an important role in many diseases and they have a protective function also. Therefore, we must keep a balance ...
-
(The Royal Society of Chemistry, 2016)A novel hybrid nanocomposite constituted of single TiO2 nanosheets sandwiched between stearic acid self-assembled monolayers was synthesized and tested in the photodegradation of methylene blue under sunlight. The product ...
-
(Royal Soc Chemistry, 2018)Fish oil (FO) was encapsulated by conventional spray-drying (FO-W-Lec) and by ethanol spray-drying, with FO incorporated as an oil-in-ethanol emulsion (with lecithin as emulsifier, FO-EtOH-Lec) or as an oil-in-ethanol ...
-
(The Royal Society of Chemistry, England, 2022)Among vegetable oils, chia oil has been gaining interest in recent years due to its high linolenic acid content (ALA, 18:3 omega 3). The aim of this work was to study the influence of the particle size of encapsulated ...
-
(Springer, 2023)Dopamine’s ability to oxidize to aminochrome explains why this molecule may be a neurotoxic compound that induces toxicity in both cell lines and animal models. Spontaneous dopamine oxidation is prevented by vesicular ...
-
One-electron reduction of 6-hydroxydopamine quinone is essential in 6-hydroxydopamine neurotoxicity (2013)6-Hydroxydamine has widely been used as neurotoxin in preclinical studies related on the neurodegenerative process of dopaminergic neurons in Parkinson's disease based on its ability to be neurotoxic as a consequence of ...

Oxidation and catalytic properties of a binuclear copper(I) complex with a meta-xylyl spacer ligand (2003)The oxidation product of the binuclear copper (I) complex Cu2L(CIO4)2 (L = N,N′-bis-(6-methyl-2-pyridil) (2′-pyridyl)methyl m-xylylidene imine) has been isolated and structurally characterised. In the cupric species, ...
-
(Elsevier BV, 1997)In this work, the influence of oxidation during austenitizing heating in air. before quenching, on the fatigue-life of an AISI-D3 steel previously machined by electrodischarge machining, is studied. It has been determined ...
-
(Elsevier Ltd, 1997)Copper(II) complexes of the ligands (6-methyl-2,2′-dipyridyl)methane (MeDPM) and (6,6′-dimethyl-2,2′-dipyridyl)methane (diMeDPM) were prepared and used as catalysts for the oxidation of 3,5-ditert-butylcatechol to ...
-
(Elsevier, 2017)Oxidation of a phenolic group in quercetin is assumed to compromise its antioxidant properties. To address this assumption, the ROS-scavenging, Folin-Ciocalteau- and Fe-reducing capacities of quercetin and thirteen ...
-
Revealing Monoamine Oxidase B Catalytic Mechanisms by Means of the Quantum Chemical Cluster Approach (Amer Chemical Soc, 2015)Two of the possible catalytic mechanisms for neurotransmitter oxidative deamination by monoamine oxidase B (MAO B), namely, polar nucleophilic and hydride transfer, were addressed in order to comprehend the nature of ...
-
(1998)Indirect evidence has suggested that K-Cl cotransport in human and sheep erythrocytes is activated physiologically by a serine-threonine phosphatase. It is activated experimentally by H2O2 and by staurosporine, a kinase ...
-
(Elsevier, 2020)The present investigation reports the modification of Ti substrates by a plasma technique to enhance their physio-chemical properties as biocompatible substrates for the deposition of artificial membranes. For that purpose, ...
-
(2014)In this paper, a series of six dihydropyridine-fused coumarins were synthesized and electrochemically characterized in dimethylformamide (DMF). Dihydropyridine ring oxidation on glassy carbon electrode (GCE) for condensed ...
