ABSTRACT This study provides a comprehensive investigation of antimicrobial additives (ZnO/AgNPs and SiO 2 /AgNPs) on the properties biodegradable ternary blends composed poly(hydroxybutyrate) (PHB), poly(lactic acid) (PLA), polycaprolactone (PCL) by examining morphology, thermal stability, crystallinity index, cell viability these blends. Overall, transmission electron microscopy (TEM) analysis revealed that AgNPs exhibited comparable sizes, whereas ZnO was significantly larger, which...
Propolis has been used worldwide for years in folk medicine and currently marketed by the pharmaceutical industry. In Brazil, propolis was classified into 13 groups based on their organoleptics physicochemical characteristics. The 13th type named red an important source of investigation since late 90s. Their property comes from countless compounds, including terpenes, pterocarpans, prenylated benzophenones especially flavonoids. This last compound class indicated as responsible its potent...
Salvia officinalis (Lamiaceae) has been used in south of Brazil as a diary homemade, food condiment and tea-beverage for the treatment several disorders. The objective this study was to characterize chemical compounds hydroalcoholic (ExtHS) aqueous (ExtAS) extract from (L.) by gas chromatography-mass spectrometry (GC-MS) high-resolution electrospray ionization mass (ESI-QTOF MS/MS), evaluate vitro ability scavenge free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH•)...
Wound infections are the main complication when treating skin wounds. This work reports a novel antimicrobial material using green synthesized zinc oxide nanoparticles (ZnONPs) incorporated in polymeric fibers for wound healing purposes. ZnONPs promising nanomaterial with high activity against range of microorganisms, including drug-resistant bacteria. The electrospun were obtained polyacrylic acid (PAA) and polyallylamine hydrochloride (PAH) loaded from Ilex paraguariensis leaves spherical...
Natural products continue to be an invaluable resource of anticancer drug discovery in recent years. Propolis is known for its biological activities such as antimicrobial and antitumor effects. This study assessed the effects Brazilian red propolis (BRP) on apoptosis migration potential human bladder cancer cells. The effect BRP ethanolic extract (25, 50, 100 μg/mL) 5637 cells was determined by MTT, LIVE/DEAD, (scratch assay) assays. Apoptosis induction investigated through flow cytometry...
Most studies of Brazilian red propolis have explored the composition and biological properties its ethanolic extracts. In this work, we chemically extracted characterized essential oil (EOP) assessed adjuvant, antiparasitic cytotoxic activities. The chemical EOP was analyzed using gas chromatography with mass spectrometry (GC-MS). tested for in vitro activity against Trichomonas vaginalis (ATCC 30236 isolate); trophozoites were treated different concentrations (ranging from 25 to 500 μg/mL)...
Since early times, propolis has been used in folk medicine. The red propolis, collected the northeast region of Brazil highlighted due to its popular use as an antimicrobial, with anti-inflammatory and healing properties, which are associated chemical composition. Here, we combine a bacterial membrane treat wounds diabetic mice. This work aims evaluate biocurative from cellulose mice wound model. Biocuratives different extracts were produced. qualification quantification presence compounds...
Diseases caused by infections are becoming harder to treat as the antibiotics used become less effective. A combination of strategies develop active biomaterials that enhance antibacterial effects desirable, especially ones cause fewer side and promote healing properties. The nanotechnology with substances have intrinsic activity can result in advance innovative biomedical materials. In this sense, goal work is provide a summary natural rubber latex materials obtained from Hevea brasiliensis...
Bacteria are an old concern to human health, as they responsible for nosocomial infections, and the number of antibiotic-resistant microorganisms keeps growing. Copper is known its intrinsic biocidal properties, therefore, it a promising material combat infections when added surfaces. However, properties in presence light illumination have not been fully explored, especially regarding use microsized particles since nanoparticles taken over all fields research subjugated microparticles...
Red propolis is a natural resin mixture produced by honeybees and presents source of active compounds with variety biological activities. In this study, we describe the chemical characterization potential antitumor activity total extract Brazilian red its fractions. Fractions were obtained through column chromatography revealing 14 different in all samples, which determined distinguished other isobar molecules fragmentation pathways ESI-MS/MS positive mode. Some as cis-asarone or...
Pyrazoles are compounds of synthetic origin, and constitute a group nitrogen heterocyclic that have shown several biological activities. Their transformations into other biologically active molecules been exploited since the early 1960s. This review describes work on environment-friendly synthesis bioactive pyrazoles. The covers mainly data published over last five years (2007–2012).
