Biopolymer from Annona muricata residues as a potential sustainable raw materia...
Ramos, Igor F. S.; Dias, Samuel C.; Lopes, Talissa B. C.; Júnior, Francisco T. dos S. Silva; Araújo, Ricardo de; Gutierrez, Stanley J. C.Annona muricata is a fruit species belonging to the Annonaceae family, which is native to the warmer tropical areas of North and South America. A large amount of discarded residue from A. muricata is of interest for obtaining new industrial inputs. To propose the applications of the biopolymer from A. muricata residues (Biop_AmRs), this study aimed to characterize this input chemically and functionally, as well...
Emerging applications of Sterculia striata gum in medical, pharmaceutical, and ...
Freitas, Alessandra Ribeiro; Ribeiro, António José; Santos, Pauline Sousa dos; Oliveira, Thaísa Cardoso de; Oliveira, Jabson Herber Profiro deTrees of the genus Sterculia produce acidic polysaccharides with high viscosity and the ability to form gels in water. This work emphasized the species Sterculia striata and the uses of its plant derivatives, such as seeds, fruits, stem bark, and exudates. The species showed prospects for industrial application (seeds with high protein content, fruits with antioxidant potential, and stem bark with anti-inflamma...
Modification of chicha gum antibacterial activity, ex vivo mucoadhesion, antiox...
Freitas, Alessandra R.; Ribeiro, António J.; Ribeiro, Alessandra B.; Collado-Gonzalez, Maria Del Mar; Silva, Luís R.; Alves, Luís; Melro, ElodieThe aim of the present work was to modify the exuded gum of Sterculia striata tree by an amination reaction. The viscosity and zero potential of the chicha gum varied as a function of pH. The modification was confirmed by X-ray diffraction (XRD), infrared spectroscopy (FTIR), size exclusion chromatography (SEC), zeta potential, thermogravimetric analysis (TG), and differential scanning calorimetry (DSC). Furthe...
Biopolymeric materials used as nonviral vectors: a review
Santos, Jailson de Araújo; Liarte, Daniel Barbosa; Ribeiro, Alessandra Braga; Rizzo, Marcia dos Santos; Costa, Marcília Pinheiro da; Osajima, Josy A.Bacterial transformation and gene transfection can be understood as being the results of introducing specific genetic material into cells, resulting in gene expression, and adding a new genetic trait to the host cell. Many studies have been carried out to investigate different types of lipids and cationic polymers as promising nonviral vectors for DNA transfer. The present study aimed to carry out a systematic ...
Effect of cerium-containing hydroxyapatite in bone repair in female rats with o...
Vieira, Ewerton; Silva, Marcos; Maia-Filho, Antonio; Ferreira, Daniel; Figuerêdo-Silva, José; Rovaris, Karla; Fialho, Ana Cristina; Leite-Oliveira, AnaOsteoporosis is a public health problem, with bone loss being the main consequence. Hydroxyapatite (HA) has been largely used as a bioceramic to stimulate bone growth. In our work, a cerium-containing HA (Ce-HA) has been proposed and its effects on the antimicrobial and bone-inducing properties were investigated. The synthesis of the materials occurred by the suspension–precipitation method (SPM). The XRD (X-ra...
Antimicrobial efficacy of building material based on ZnO/palygorskite against g...
Rosendo, Frederico R.G.V.; Pinto, Lucas I.F.; Lima, Idglan S. de; Trigueiro, Pollyana; Honório, Luzia M. de C.; Fonseca, Maria GardênniaThis study investigated ZnO nanoparticles immobilized in palygorskite clay mineral (Pal) that acted as an inorganic antimicrobial agent in a commercial mortar aiming to control microorganisms and improve safety and stability for building applications. ZnO/Pal nanocomposites were obtained by sol-gel methods at pH 7 and 11 and were calcined at 250 °C and 400 °C to evaluate different synthesis parameters. The mort...
