The world coffee consumption has been growing for its appreciated taste and beneficial effects on health. residual biomass of coffee, originated in the food industry after oil extraction from beans, called beans press cake, attracted interest as a source compounds with antioxidant activity. This study investigated chemical composition aqueous extracts cake (AE), their activity, effect topical application skin wound healing, animal model, hydrogels containing AE, chlorogenic acid (CGA),...
Electrospun materials have been widely explored for biomedical applications because of their advantageous characteristics, i.e., tridimensional nanofibrous structure with high surface-to-volume ratio, porosity, and pore interconnectivity. Furthermore, considering the similarities between nanofiber networks extracellular matrix (ECM), as well accepted role changes in ECM hernia repair, electrospun polymer fiber assemblies emerged potential incisional repair. In this work, we describe...
Objectives Anxiety and depression are relevant comorbidities in asthma, but, Portugal Spain, data on this topic scarce. We assessed, patients with the frequency of anxiety using Hospital Depression Scale (HADS) European Quality Life Five Dimension Questionnaire (EQ-5D); level agreement between these questionnaires, factors associated symptoms. Methods This is a secondary analysis INSPIRERS studies. A total 614 adolescents adults persistent asthma (32.6±16.9 years, 64.7% female) were...
In this work photocatalytic ethylene degradation (TiO2-UV) was applied in green cherry tomatoes with the aim to control biochemical and physiological changes during ripening. Photocatalytic process performed at 18 °C ± 2 85% HR for 10 days using continuous air flux. Ethylene, O2 CO2 concentration from under TiO2-UV (c) fruits, were measured by GC-MS days. After that, stored 20 During photocatalysis process, completely degraded 28.73 nL/g. Respiration rate lower fruits than control. storage...
Pectin (PC) extracted from a solid residue cassava roots (Manihot esculenta Crantz) was used to coat nanoparticles (NP) containing β-carotene (BC) aiming at the gastrointestinal administration of this lipophilic nutraceutical. The NP were prepared by spontaneous emulsification method using food grade components. Pectin-coated have been successfully as confirmed increased particle size and negative surface charges due pectin's anionic nature. showed spherical shape monodisperse distribution,...
The typical undrained behaviour observed in brittle non-plastic soil is ruled by the combination of density and stress levels. Some specific silty sandy mining waste with particles morphologies that generate high smallstrain stiffness to strength ratios when increasing deviatoric ( q ) paths tend decrease mean effective p´ may drop down before reaching frictional critical sate. ratio between peak (or yield) value S u = /2) corresponding usually associated a locus q-p´ commonly straight...
Objective: Target of this study was to test the capacity chondroitin sulfate (CS) and glucosamine (GS) induce in vivo angiogenesis. Methods: The proangiogenic activity these compounds analyzed through assays chorioallantoic membrane (CAM) chick embryo dorsal skin vascularization mice, but before realized a cell viability assay with human umbilical veins endothelial cells (HUVEC). Results: In assay, concentrations tested between 30 3000 μg/ml showed reduction viable HUVEC number. CAM CS GS an...
Propolis is commonly used to treat dermal inflammatory disorders and has shown great potential in experimental wound healing.However, propolis usually requires organic solvents for solubilization, which hampers its use healing.In this regard, nanotechnology arises as an important tool towards the development of aqueous systems with application context, present study aimed develop nanoparticles evaluate, vitro vivo, their early-stage healing.Propolis Nanoparticles (PN) were characterized...
Electrospinning is a promising technique to generate scaffolds for delivery systems and nerve tissue engineering. This study aimed investigate the suitability of polyethylene glycol (PEG) as an agent prolong circulation time in growth factor (NGF) encapsulated into polycaprolactone (PCL) electrospun fibers. Three molecular weights (400, 1500, 35000 Da) concentrations (1, 5, 10% ratio PCL) PEG were studied. The effect on NGF from was evaluated by neuronal differentiation using PC12 cells....
