Chitosan/collagen biomembrane loaded with 2,3-dihydrobenzofuran for the treatme...
Braz, Elton Marks Araujo; Silva, Solranny Carla Cavalcante Costa; Alves, Michel Muálem Moraes; Carvalho, Fernando Aécio Amorim; Magalhães, RuiIn this work, chitosan/collagen-based membranes loaded with 2,3-dihydrobenzofuran (2,3-DHB) were developed through a simple solvent-casting procedure for use in the treatment of cutaneous Leishmaniasis. The obtained membranes were characterized by elemental analysis, FTIR, TG, DSC, and XRD. Porosity, swelling, mechanical properties, hydrophilicity, and antioxidant activity were analyzed. In addition, assessment...
Biopolymer from water kefir as a potential clean-label ingredient for health ap...
Lucena, Monalisa de Alencar; Ramos, Igor Frederico da Silveira; Geronço, Maurycyo Silva; Araújo, Ricardo de; Filho, Francisco Lopes da SilvaThe present work aimed to characterize the exopolysaccharide obtained from water kefir grains (EPSwk), a symbiotic association of probiotic microorganisms. New findings of the technological, mechanical, and biological properties of the sample were studied. The EPSwk polymer presented an Mw of 6.35 x 10(5) Da. The biopolymer also showed microcrystalline structure and characteristic thermal stability with maximum...

Study of the effect of solvent on acetylate cashew gum-based nanoparticles prop...
Macedo, Karolina Carneiro Morais; Chaves, Luíse Lopes; Vieira, Alexandre Couto Carneiro; Nadvorny, Daniela; Paula, Regina Célia Monteiro deThe aim of this work was to investigate the influence of acetone and dimethyl sulfoxide (DMSO) on acetylated cashew gun (ACG) nanoparticles parameters and to assess their antimicrobial activity. C1 nanoparticles presented smaller size (81.3 nm) than compared to C2 (115.7 nm). Although, acetone formed particles with lower PDI value. Both C1 and C2 presented negative zeta potential (-39.8 and -31.7 respectively)....
Development of composite scaffolds based on cerium doped-hydroxyapatite and nat...
Santos, Marcus Vinicius Beserra dos; Rocha, Lorenna Bastos Nogueira; Vieira, Ewerton Gomes; Oliveira, Ana Leite; Lobo, Anderson OliveiraHydroxyapatite (HAp) is a ceramic material composing the inorganic portion of bones. Ionic substitutions enhance characteristics of HAp, for example, calcium ions (Ca2+) by cerium ions (Ce3+). The use of HAp is potentialized through biopolymers, cashew gum (CG), and gellan gum (GG), since CG/GG is structuring agents in the modeling of structured biocomposites, scaffolds. Ce-HApCG biocomposite was synthesized us...
