Chronic kidney disease (CKD), a pressing global health issue, affects millions and leads to end-stage renal (ESRD). Hemodialysis (HD) is crucial treatment for ESRD, yet its limited efficiency in removing protein-bound uremic toxins (PBUTs) results high morbidity mortality rates. A affinity of pharmaceutical drugs human serum albumin (HSA) can be leveraged compete effectively with PBUTs the same HSA binding sites, thereby enabling them capable displacing these toxins. One such drug ibuprofen...
This research investigates the production of galactomannan from Adenanthera pavonina L. in its crude form and subsequent crosslinking with glutaraldehyde under various pH conditions. The study involved creation films sponges these materials, followed by a comprehensive analysis their structural, thermal, swelling, electrical properties. Galactomannan was crosslinked fixed concentration 0.2 mol/L glutaraldehyde, levels ranging 3 to 7. These were prepared through slow solvent evaporation...
Galactomannans are polysaccharides obtained from legume seed extraction. They present a chemical structure consisting of D-mannose chains linked by glycosidic bonds and galactose branches. The main focus lies in their use as thickeners the food industry, aimed at improving dielectric properties during heating processes within radiofrequency microwave ranges. In this work, prepared galactomannan samples were electrically analyzed through impedance spectroscopy, which is powerful physical...
Aiming of self-sustainable production, the search for biodegradable and biocompatible materials has brought with it need to know physicochemical dielectric characteristics polysaccharide-based composite structures, which can be used as important promising raw biotechnology electronic industries. Galactomannans are polysaccharides, extracted from seeds microbiological sources, consisting mannose galactose. In this context, work aimed extract, purify characterize by XRD, FTIR impedance...
A lithium ferrite with the general formula LiFe5O8 was prepared by a new variation of ceramic method, in which high-energy mechanical milling and calcinations Li2CO3 Fe2O3 were used. In this paper, we present study structural electrical properties phase. We also investigate effects use galactomannan as binding option compared traditional material like glycerol.
Bioceramics are used to repair, rebuild, and replace parts of the human body, e.g., bones, joints teeth, in form powder, coatings or prostheses. The synthetic hydroxyapatite [Ca10(PO4)6(OH)2 (HAP)] based on calcium phosphate has been widely medical dental areas due chemical similarity with inorganic component bone tissue. In this work, nanocrystalline powders were synthesized by solid-state reaction method sintered a galactomannan chitosan blend. bioceramics studied prepared from 70%, 80%...
As plantas medicinais vêm acompanhando a humanidade desde sua existência, sendo utilizadas como: remédios, rituais, tinturas, dentre outras. Cientistas de todo o mundo estudam efeito medicinal diversas plantas. A planta Morinda citrifolia Linn., conhecida popularmente como noni, apresenta na medicina empírica capacidades farmacológicas fim curar enfermos. Esta pesquisa busca identificar metabólitos secundários bioativos presentes folha e fruto do avaliar apenas potencial antioxidante da...
The study's aim was to synthesize a crystalline film formed by L‐threonine crystals complexed with Cu 2+ ions (LTCu) dispersed in galactomannan (Gal) solution as well characterize its structural, vibrational, and thermal properties. Gal(LTCu) films were prepared the addition of copper II L‐threoninate concentrations 0.25, 0.50, 0.75 2% Gal solution. To properties, we used X‐ray diffraction (XRD), UV–Vis Raman spectroscopy, thermogravimetry, analyses (TG‐DTA). XRD showed that are have...
RESUMO A hidroxiapatita é um fosfato de cálcio considerada como biomaterial utilizada em restaurações ósseas, uma vez que apresenta características semelhantes à fase mineral do tecido ósseo. Por possuir diversos métodos obtenção, a síntese pó tem estimulado interesse pesquisas acadêmicas e indústrias, pois as condições dos reagentes influenciam na estrutura, morfologia aplicação composto final desejado. Este trabalho propende realizar estudo comparativo sobre utilizando iguais, por dois...
Abstract The development of bioactivity in bioinert metallic alloys is a field interest aiming to improve some aspects these materials for implant applications. New Co 63 Cr 28 W 9‐x Ta x with different concentrations ( = 0, 2, 4, 6, and 9% w/w) were synthesized the work reported here. characterized by x‐ray diffraction, volumetric density, Vickers microhardness, atomic force microscopy, scanning electron microscopy (SEM), energy‐dispersion spectroscopy (EDS). Bioactivity properties...
