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...
Antibacterial and healing effect of chicha gum hydrogel (Sterculia striata) wit...
Lima, Idglan Sá; Ferreira, Maria Onaira Gonçalves; Barros, Esmeralda Maria Lustosa; Rizzo, Marcia Santos; Santos, Jailson de AraujoChicha gum is a natural polymer obtained from the Sterculia striata plant. The hydroxyl groups of its structure have a chemical affinity to form hydrogels, which favors the association with biologically active molecules, such as nerolidol. This association improves the biological properties and allows the material to be used in drug delivery systems. Chicha gum hydrogels associated with nerolidol were produced ...
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...

Potential wound healing effect of gel based on chicha gum, chitosan, and maurit...
Ferreira, Maria Onaira Gonçalves; Ribeiro, Alessandra Braga; Rizzo, Marcia S.; Oliveira, Antonia Carla de Jesus; Osajima, Josy AnteveliWounds are considered a clinically critical issue, and effective treatment will decrease complications, prevent chronic wound formation, and allow rapid healing. The development of products based on naturally occurring materials is an efficient approach to wound healing. Natural polysaccharides can mimic the extracellular matrix and promote cell growth, thus making them attractive for wound healing. In this con...

No. of bitstreams: 0 Previous issue date: 2021-12-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); The production of edible film from onion (Allium cepa L.) to be applied as packaging is attractive, due to its chemical properties and biodegradable characteristics. Thus, we tested the hypothesis that edible onion film can positively influe...
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 ...
