Healing activity evaluation of the galactomannan film obtained from Cassia gran...
Albuquerque, Priscilla B. S.; Soares, Paulo A. G.; Aragão-Neto, Adelmo C.; Albuquerque, Giwellington S.; Silva, Luís C. N.; Lima-Ribeiro, Maria H. M.Galactomannan films from Cassia grandis seeds, associated or not with Cramoll 1,4, were used on topical wounds of rats for the evaluation of the healing process during 14 days. All of the films were evaluated by cytotoxic assay, FTIR and lectin hemagglutinating activity (HA). Forty-five male rats were submitted to aseptic dermal wounds (Ø = 0.8 cm) and divided in groups (n = 15): control, test 1, and test 2, tr...
Investigating a galactomannan gel obtained from Cassia grandis seeds as immobil...
Albuquerque, Priscilla B. S.; Silva, Caroline S.; Soares, Paulo A. G.; Barros Junior, Wilson; Correia, Maria T. S.; Coelho, Luana C. B. B.Characterization, with emphasis on the rheological properties, of Cassia grandis seeds galactomannan gel containing immobilized Cramoll 1,4 is presented. The gels, with and without immobilized Cramoll 1,4, were evaluated along time by rheometry, pH, color, microbial contamination and lectin hemagglutinating activity (HA). Rheological determinations confirmed the gels to be very stable up to 30 days with variati...
Approaches in biotechnological applications of natural polymers
Albuquerque, Priscilla B. S.; Coelho, Luana C. B. B.; Teixeira, J. A.; Carneiro-da-Cunha, M. G.Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. ...
Removal of tetracycline from contaminated water by Moringa oleifera seed prepar...
Santos, Andréa F. S.; Matos, M.; Sousa, A. M.; Costa, Cátia; Nogueira, Regina; Teixeira, J. A.; Paiva, Patrícia M. G.; Parpot, PierThe aim of this study was to evaluate tetracycline antibiotic (TA) removal from contaminated water by Moringa oleifera seed preparations. The composition of synthetic water approximate river natural contaminated water and TA simulated its presence as an emerging pollutant. Interactions between TA and protein preparations (extract; fraction and lectin) were also evaluated. TA was determined by solid phase extrac...
Anti-inflammatory and antinociceptive activities of Bauhinia monandra leaf lectin
Campos, Janaína K. L.; Araújo, Chrisjacele S. F.; Araújo, Tiago F. S.; Santos, Andréa F. S.; Teixeira, J. A.; Lima, Vera L. M.; Coelho, Luana C. B. B.A galactose-specific lectin from Bauhinia monandra leaves (BmoLL) have been purified through ammonium sulphate fractionation followed by guar gel affinity chromatography column. This study aimed to evaluate the potential anti-inflammatory and antinociceptive activity of pure BmoLL in mice. Anti-inflammatory activity was evaluated by 1% carrageenan-induced inflammation in mice treated with BmoLL. Acetic acid-ind...
Moringa oleifera: Resource management and multiuse life tree
Santos, Andréa F. S.; Luz, Luciana A.; Pontual, Emmanuel V.; Napoleão, Thiago H.; Paiva, Patrícia M. G.; Coelho, Luana C. B. B.Moringa oleifera Lamarck (Moringaceae family) is a plant native from the Western and sub-Himalayan parts of Northwest India, Pakistan and Afghanistan. This species is widely cultivated across Africa, South-East Asia, Arabia, South America and Caribbean Islands. M. oleifera culture is also being distributed in the Semi-Arid Northeast of Brazil. It is a multiuse life tree with great environmental economic importa...
Strategies to obtain lectins from distinct sources
Santos, Andréa F. S.; Napoleão, Thiago H.; Bezerra, Rosiely F.; Carvalho, Elba V. M. M.; Correia, Maria T. S.; Paiva, Patrícia M. G.Lectins are proteins or glycoproteins that bind specifically to mono, oligo or polysaccharides. They are important biotechnological tools and have been isolated from microorganisms, higher fungus, lichens, plants and animals. Different purification strategies are used to obtain pure lectins. It is important to approach the principles of each method to be used in protein purification before start to work in this...
Moringa oleifera: a multipurpose tree with water coagulant seed proteins
Santos, Andréa F. S.; Paiva, Patrícia M. G.; Coelho, Luana C. B. B.In this review Moringa oleifera, a tree with great environmental economic importance in industry and medicine, will be approached. Distinct parts of the plant have bioactive properties and can be used to different purposes. The leaves are good sources of protein and are used in human and animal diets. Leaves have growth-promoting hormones, are rich in folate and showed hypocholesterolemic, antiviral, antioxidan...
Lectins : important tools for biocontrol of Fusarium species
Santos, Andréa F. S.; Napoleão, Thiago H.; Paiva, Patrícia M. G.; Coelho, Luana C. B. B.Lectins are proteins from non-immune origin, containing two or more binding sites to mono or oligosaccharides. Plant lectins, found in different plant tissues, show a marked heterogeneity with respect to their molecular structure and sugar-binding specificity. Fungi are frequently pathogens of cultivated plant species representing one of the main causes of crop losses. Growth of fungi has been considered a majo...
