The interactions of low density lipoprotein (LDL) and apolipoprotein (apo) B-100 segments with chondroitin-6-SO4 rich aortic proteoglycans aggregate (CSPG) were studied by using quantitative frontal elution affinity chromatography. the agarose-CSPG was higher for LDL than very high not bound. from different individuals had dissociation coefficients (Kd) 28 to 179 nM. Experiments tryptic hydrolysates apo B suggested that capacity bind CSPG resides in protein. Nine hydrophilic peptides, 12 26...
The reversible interaction of low density lipoprotein (LDL) with arterial chondroitin sulfate proteoglycans (CSPGs) or glycosaminoglycans (GAGs) selects LDL particles a high affinity for sulfated GAGs and also induces modifications in apolipoprotein B (apo B) the lipid organization lipoprotein. In present work we studied effect that polysaccharides has on susceptibility to vitro oxidation. For this purpose soluble, nonaggregated CSPG- GAG-treated was subjected oxidation presence 5 microM...
The rapid industrialization and energy transition, as well social pressure is increasing the current needs for metals. This results in an demand, so exploitation of more natural resources. In this scenario, a alternative to minimise lack resource recycling industrial waste by-products, such electrical electronic waste, lithium batteries, solar panels, blast furnace slag, etc. Many articles focus on recovery metals by hydrometallurgical methods are published. Currently, one great scientific...
Macrophages and arterial chondroitin sulfate proteoglycans (CSPG) are probably associated with extracellular intracellular lipoprotein deposition during atherogenesis. We found that human CSPG can be used to select subclasses from low density (LDL) different structural properties capacities interact monocyte-derived macrophages (HMDM). Four subclasses, LDL(PG)1 LDL(PG)4, in order of decreasing CSPG-complexing capacity, were prepared characterized terms their ability HMDM. The LDL highest...
Rolling mill scale is a solid byproduct of the steelmaking industry that contains metallic iron and three types oxides: wüstite, haematite magnetite. It also traces non-ferrous metals, alkaline compounds oils from rolling process. A study was made reduction to sponge using coke at different temperatures times. The reduced samples were studied by X-ray diffraction scanning electron microscopy. Oxygen analysis carried out combustion in LECO oven. Sponge successfully produced for reuse electric...
The char produced in the thermolysis of granulated scrap tyres has few market outlets, reducing economic viability thermolytic process. This paper reports potential this as a low-cost precursor porous carbons. tyre-derived was demineralized either alkaline or acidic media to reduce its ash, zinc, sulfur, and silica contents. lowest impurity content achieved with an HNO3/H2O treatment. resulting then subjected activation by KOH CO2. Brunauer-Emmett-Teller (BET)-specific surface area activated...
This work reports the preparation of activated carbons via hydrothermal treatment at 523 K/30 bar two common winemaking wastes: bagasse and cluster stalks. The produced by above were turned into their exposure to KOH carbonization 1073 K. These then subjected Raman spectroscopy, Fourier transform infrared scanning electron microscopy examination, determination Brunauer–Emmett–Teller surface area. ability adsorb methylene blue in aqueous solution was examined, determining influence time,...
Deep eutectic solvents (DESs) have emerged as a greener alternative to other more polluting traditional and attracted lot of interest in the last two decades. The DESs are less toxic dissolvents lower environmental footprint. This paper presents an synthesis method classical heating–stirring method. ultrasound is one most promising methods for terms yield energy efficiency. Therefore, was studied obtain hydrophobic (Aliquat 336:L-Menthol (3:7); Lidocaine:Decanoic acid (1:2)) hydrophilic...
La generación, por parte de las industrias, efluentes líquidos conteniendo sustancias orgánicas e inorgánicas, es un peligro potencial tanto para los humanos como el medio ambiente, siendo necesaria la eliminación estos elementos tóxicos disoluciones que contienen. Para conseguir este fin, se están aplicando diversas técnicas y entre ellas tecnologías membranas líquidas soportadas, demostrando sus aptitudes metales contenidos en líquidos. Las resultan unión poliméricas tecnología extracción...
This work describes the adsorption of Pb2+ in aqueous solution onto an activated carbon (AC) produced from winemaking waste (cluster stalks). After characterizing AC using Fourier transform infrared spectroscopy (FTIR) and micro-Raman spectroscopy, influence different physico-chemical factors (stirring rate, temperature, pH, adsorbent concentration, etc.) on its capacity to adsorb was examined. Kinetic thermodynamic studies showed that follows a pseudo-second-order kinetic model fits...
The slag from the extraction processes of metals their ores may contain valuable components that, if adequately recovered, can be reintroduced in technological life cycle. This is case for material obtained Penouta mines North Spain. These mineral sites are a main source tin cassiterite. submitted to pyrometallurgical process separate tin, however cassiterite not only present veins, and large amounts other minerals normally discarded, constituting slag. In case, besides cassiterite, one most...
