Evening primrose (Oenothera biennis L., Onagraceae) seeds oil has great economic importance due to its wide industrial application, mainly for medicines and nutraceutics. However, our knowledge, it remains almost unexplored regarding development of innovative formulations, such as nanoemulsions. On the present study, required Hydroprophile–Lipophile Balance evening was determined (HLB 12) a stable nanoemulsion (Day 1: mean droplet size: 214.3 ± 0.69 nm, polydispersity index: 0.253 0.012. Day...
The use of chitosan biofilm in biomedical fields has a vast therapeutic potential due to useful properties such as biodegradability and antimicrobial activity, however, achieve successful application some physicochemical need be improved.In this context, the addition glycerol is an alternative improve its wettability flexibility.Thus, low high concentrations plasticizer were added biomaterial for later characterization regarding wettability, microstructure, mechanical chemical...
The plant species Acmella oleracea L. is used in the north of Brazil for treatment a range illnesses, such as tuberculosis, flu, cough, and rheumatism an anti-inflammatory agent; besides, hydroethanolic formulations with this are popularly female aphrodisiac agent. However, currently, there no studies performed evaluating its effect on embryonic development. Hence, research aimed to evaluate effects extract A. (EHFAo) reproductive performance (parental) development (F1 generation) zebrafish,...
Dyslipidemias are lipid metabolism alterations that cause increased levels of serum lipoprotein, cholesterol, and triglycerides. These associated with a higher incidence cardiovascular diseases risk factor for atherosclerosis development. This study aimed to evaluate the effect Rosmarinus officinalis essential oil (EORO, 100 mg/kg) its nanoemulsion (NEORO, 500 µg/kg) on Triton coconut saturated-fat-induced (CSF) dyslipidemias using Wistar rats. The phytochemical evaluation EORO performed by...
Lipases (EC 3.1.1.3) are hydrolases that catalyze triglycerides hydrolysis in free fatty acids and glycerol. Among the microorganisms produce lipolytic enzymes, entophytic fungi stand out. We evaluated 32 of different genera, Pestalotiopsis, Aspergillus, Trichoderma, Penicillium, Fusarium, Colletotrichum, Chaetomium, Mucor, Botryodiplodia, Xylaria, Curvularia, Neocosmospora Verticillium, isolated from Euterpe oleracea Mart. (Açaizeiro) Brazilian Amazon for lipase activity. The presence was...
Background: Biodiesel represents an alternative energy source with economic, social, environmental, and technological advantages over nonrenewable fuels. Objective: This study investigated two oils derived from plants of the Brazilian Amazon, andiroba (Carapa sp.) oil babassu (Orbignya oil, as possible triacylglyceride sources for production biofuels by lipase B Candida antarctica (CALB). Methods: The biodiesel ethylic enzymatic catalyst was carried out in 3-mL Erlenmeyer flasks containing...
In this bioremediation study, the fungus Penicillium sp. isolated from kefir grains was evaluated for its resistance to copper in culture medium. cultivated liquid medium prepared using 2% malt-agar at pH 7.0. Biomass of significantly reduced, but only when 800 mg·L-1 Cu(NO3)2 nitrate used. The effect on radial growth experiments combining different values and inorganic contaminant showed an inhibition 73% 4.0, 75% 7.0 77% 9.0 Thus, even though could be inhibited with relatively high doses...
The species Trattinnickia rhoifolia Willd, (T. rhoifolia), which belongs to the Burseraceae family, is widely used in ethnopharmacological cultural practices by traditional Amazonian people for anti-inflammatory purposes, sometimes as their only therapeutic resource. Although it teas, infusions, macerations and food, still unexplored regard its pharmacophoric potential chemical profile. Therefore, aim of this study was conduct a phytochemical characterization hydroethanolic extract T. leaves...
Context The botanical species Bauhinia guianensis Aublet (Leguminosae-Cercidoideae) is traditionally used in the Amazon for medicinal purposes.
Biodegradable films based on poly(vinyl alcohol) (PVA) and bioactive substances have been receiving great attention in the food industry, as they offer an eco-friendly alternative to conventional packaging. In this context, we synthesized PVA (PVAF) containing silk fibroin (SF) formulations functionalized with copaiba oleoresin (CO) for use Four different were prepared using casting method, varying SF-CO concentrations from 0 15% (v/v) matrix. The samples characterized regarding morphology,...
Diabetes mellitus is a prevalent disease in the Portuguese population and associated with significant morbidity mortality. Its proper therapeutic management multifactorial, lifestyle habits having major impact. Studies show that poorer metabolic control deficient knowledge related to diabetes, lower self-efficacy, limited patient empowerment. The aim of this study was characterize diabetic patients' about their using Knowledge Test (DKT) assess potential correlation between control. A...
Inorganic contaminant contamination poses the greatest threat to environment and human health. It has been recently reported that probiotics protect body from inorganic damage by bioabsorption capacity of its components. Kefir is a beverage obtained through fermentation metabolized Lactobacillus yeasts aggregate forming grains kefir. In order isolate resistant microorganism, kefir were crushed supernatant was inoculated in malt-gar medium (2%) cultured for 120 hours. Occurred formation halos...
Endophytic fungi are those that present part of their life cycle in healthy tissues different plant hosts symbiosis without causing harm. At the same time, fungus-plant makes it possible for microorganisms to synthesize own bioactive secondary metabolites while stationary stage. Such microorganism-derived contribute. Therefore, this work aimed to. To accomplish this, endophytic fungus Trichoderma asperellum was isolated from Bertholletia excelsa (Brazil nut) almonds. The cultivated and...
This work aimed to carry out a bioremediation study evaluate the resistance of Penicillium sp. isolated from kefir grains for treatment copper. The fungal culture medium was prepared using 2% malt-agar at pH 7.0 in which inoculated. growing liquid showed decrease biomass presence Cu(NO3)2 (800 mg.L-1), suggesting that metal impacts growth rate fungus. Moreover, combined factors and inorganic contaminant impacted radial fungus, causing inhibition 73% 4.0, 75% 7.0, 77% 9.0 compared control....
