The objective of this study was to investigate the feasibility incorporating mango and acerola pulps into a biodegradable matrix as source polyphenols, carotenoids, other antioxidant compounds. We also sought evaluate efficacy antioxidants in film-forming dispersions using response surface methodology design experiment. bio-based films were used pack palm oil (maintained for 45 days storage) under accelerated oxidation conditions (63% relative humidity 30 °C) simulate storage total...
Biosurfactants have attracted considerable attention because of their lower toxicity, biocompatibility, and effectiveness over chemical surfactants. The use renewable sources the concept sustainable production for such biomolecules supports increased demand eco-friendly products. Herein, present study investigated corncobs (CC) sunflower stalks (SS) as substitutes conventional substrates in submerged fermentation with B. subtilis. agro-industrial residues were submitted to an alkaline...
Magnetoliposomes containing magnetite, soy lecithin, stigmasterol, and beta-sitosterol of the mean size minor than 160 nm were obtained by a scalable green process using autoclave sonication without organic solvents. The formation, liposome, linkage, encapsulation magnetite evaluated Cryo-TEM. stability magnetoliposomes after storage for 6 months at 4 °C was improved liposome size, ability lecithin to preserve phase against oxidation, pH, polydispersity index, zeta potential. iron oxide...
This work studied fast pyrolysis as a way to use the residual fiber obtained from shells of coconut ( Cocos nucifera L. var. Dwarf, Aracaju, northeastern Brazil). The bio-oil produced by and aqueous phase (formed during pyrolysis) were characterized GC/qMS GC×GC/TOF-MS. Many oxygenated compounds such phenols, aldehydes, ketones identified in extracts both phases, with high predominance phenolic compounds, mainly alkylphenols. Eighty-one 42 using GC/qMS, 95 68 same samples better performance...
The anti-inflammatory properties of Turnera subulata have been evaluated as an alternative drug approach to treating several inflammatory processes. Accordingly, in this study, aqueous and hydroalcoholic extracts T. flowers leaves were analyzed regarding their phytocomposition by ultrafast liquid chromatography coupled mass spectrometry, assessed vitro inflammation model, using LPS-stimulated RAW-264.7 macrophages. phytochemical profile indicated vitexin-2-O-rhamnoside important constituent...
The indiscriminate use of oral ferrous sulfate (FeSO4) doses induces significant oxidative damage to health. However, carotene-rich foods such as buriti oil can help the endogenous antioxidant defense and still maintain other body functions. This study aimed assess effects intake in iron-overloaded rats by FeSO4 administration. Buriti has β-carotene (787.05 mg/kg), α-tocopherol (689.02 a predominance monounsaturated fatty acids (91.30 g/100 g). Wistar (n = 32) were subdivided into two...
The aim of this study was to evaluate the flavonoid content an ethanolic leaf extract from medicinal plant Rourea induta Planch. (RIEE) and investigate its hepatoprotective potential in vivo antioxidant effects.Using samples carbon tetrachloride-treated Wistar female rats treated orally with or without RIEE, we evaluated aspartate aminotransferase, alanine total bilirubin levels plasma; hepatic oxidative stress markers catalase, superoxide dismutase, glutathione peroxidase, reduced liver...
A novel, fast, low-cost and scalable methodology to prepare stable magnetoliposomes (MGLs), without the use of organic solvents, is described.The concept work based on dual soy lecithin associated a new liposome preparation methodology.Soy was used coat nanoparticles magnetite (Fe 3 O 4 @lecithin) for encapsulation Fe @lecithin (Lip-Fe @lecithin).Liposomes with size less than 160 nm, polydispersity index 0.25 zeta potential -41 mV, were prepared autoclave sonication.The liposomal...
The production and rheological properties of xanthan gum from crude glycerin fermentation, a primary by-product the biodiesel industry with environmental health risks, were evaluated. Batch fermentations (28 °C/250 rpm /120 h) carried out using glycerin, 0.01% urea 0.1% KH2PO4, (% w/v), compared to sucrose control under same operational conditions, Xanthomonas campestris strain 2103 isolate Brazil. Its maximal by fermentation was 7.23±0.1 g·L-1 at 120 h, an apparent viscosity 642.57 mPa·s,...
INTRODUCTION: Visceral leishmaniasis (VL) is an important zoonosis in relation to public health systems. Dogs are the main domestic reservoir. This study aimed investigate occurrences of canine VL Dias D'Ávila, State Bahia, Brazil. METHODS: The prevalence was evaluated by means clinical and laboratory tests on a population 312 dogs from 23 localities this municipality, using indirect immunofluorescence immunoenzymatic assays. RESULTS: Among animals examined, 3.2% 6.7% showed signs VL,...
The present study aimed to determine whether the leaves of Turnera ulmifolia Linn. var. elegans extract exert significant antioxidant activity. activity its hydroethanolic (HEETU) was evaluated by assessing (a) radical scavenging ability in vitro, and (b) vivo effect on lipid peroxidation enzyme activities. vitro assay (DPPH) clearly supported HEETU free potential. Moreover, glutathione content activities (glutathione peroxidase, superoxide dismutase catalase) were significantly enhanced...
The balance between embolic risk and bleeding represents a clinical challenge in cancer patient treatment, encouraging studies on adjuvant oncologic treatments. Thereby, this study evaluated the vitro effect of green tea extract (GTE) epigallocatechin-3-gallate (EGCG) hemostasis modulation antineoplastic melanoma cells (B16-F10) by applying platelet aggregation, angiogenesis viability cell assays. results displayed significant antiaggregant effect, corresponding to 50 80% for EGCG,...
The chemical composition of plants used in traditional medicine exhibits biologically active compounds, such as tannins, flavonoids, and alkaloids becomes a promising approach to treat microbial infections, mainly with drug-resistant bacteria.The aim the present study was evaluate hydroethanolic leaf extracts Tamarindus indica (tamarind) Manihot esculenta (cassava) antimicrobial potential against Pseudomonas aeruginosa clinical isolated Methicillin-resistant Staphylococcus...
