A avaliação in vitro da biocompatibilidade de diferentes tipos biomateriais foi realizada pelo teste citotoxicidade em cultivo células tecido conectivo camundongos, NCTC Clone 929 American Type Culture Collection. O estudo comparativo do ensaio realizado com duas metodologias: 1) difusão ágar e 2) incorporação vermelho neutro. Os resultados obtidos demonstraram que ambas as metodologias podem ser utilizadas, acordo o tipo amostra a analisada.
The long-term usage of polymer products necessitates addressing the appropriate preservation their low oxidation state that extends warranty period. addition pertinent stabilization components into composite formulations (synthesis and natural antioxidants, pristine doped oxides, clays or couples them) produces an improvement in kinetic parameters characterizing accelerated degradation occurs during high-energy exposures. competition between material ageing mitigation is controlled by...
We report here production of MGF-<sup>198</sup>AuNPs and its application for prostate tumor therapy.
The field of wound healing has seen an increase in research activity care and hydrogel-based dressings have been targeted as a solution for these applications. Hydrogels with silver nanoparticles can present many advantages this field. However, if the aggregation sterilization product not carefully considered, effectiveness or use could be limited. Therefore, current study, dressing membrane was developed using polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), agar, carboxymethyl...
Men with castration-resistant prostate cancer (CRPC) face poor prognosis and increased risk of treatment-incurred adverse effects resulting in one the highest mortalities among patient population globally. Immune cells act as double-edged sword depending on tumor microenvironment, which leads to infiltration pro-tumor (M2) macrophages. Development new immunomodulatory therapeutic agents capable targeting hence orchestrating transformation M2 macrophages anti-tumor M1, would substantially...
Abstract: Polymeric hydrogels are used as wound dressing material since these materials show advantages such pain relief, exudates absorption, barrier to microorganisms, permeability, and others. This article shows the results obtained in a study aiming know biological performance of different polymeric be contact with skin: PVP acrylate adhesive. The biocompatibility was determined by vitro assay cytotoxicity vivo using test irritability rabbits. All tested samples presented no toxicity...
Hydrogel dressings are crosslinked hydrophilic polymers able of swelling in presence water and can be used many different types wound care. In turn, care, silver has been for a long time as an effective antimicrobial agent. Recent studies have demonstrated increase its action when it is at nanometer scale, that is, nanoparticles (AgNPs), which anti-inflammatory effect on infected wounds, rashes, mesh skin grafts. The objective this work was to study hydrogel containing AgNPs from nitrate,...
Nanocompósitos à base de amido mandioca, argila sintética hectorita e açúcar invertido (plastificante) foram preparados por processo em meio aquoso (casting) produzindo filmes transparentes homogêneos.Pequenas quantidades (5-15% massa) produzem principalmente nanocompósitos esfoliados, enquanto grandes (30% promovem a formação intercalados.Os espectros FT-Raman mostram que bandas sensíveis ligação hidrogênio grânulos são progressivamente deslocadas para frequências menores quando o teor é...
