1. Biogenic synthesis of silver nanoparticles from thyme extract for functionalization of a bioactive glass produced from rice husk ash
Abstract The rice husk, agro-industrial residue, stands out for having silica, the main oxide former of the bioactive glass. To avoid contamination in this biomaterial, substances with bactericidal properties, like silver can be incorporated. Thus, the objective of this work is the synthesis of silver nanoparticles to functionalize a bioactive glass synthesi

2. Acute invasive fungal rhinosinusitis in pediatric patients with oncohematological diseases
Abstract Introduction Invasive fungal diseases represent important causes of morbidity and mortality among pediatric oncohematological patients. Acute invasive fungal rhinosinusitis is a rare and aggressive disease that occurs mainly in immunocompromised patients. The mortality rate is high and therefore, accurate and early diagnosis is essential. Objectiv

3. Epidemiological Profile of Patients with Infective Endocarditis at three Tertiary Centers in Brazil from 2003 to 2017
Abstract Background Infective endocarditis (IE) is a disease with high morbimortality and an increasing incidence. With improved diagnosis and treatment, a number of epidemiological changes have been reported over time. Objectives We sought to describe the epidemiological profile, mortality predictors, and analysis of a possible microbiological transitio

4. Evaluation of residues of β-lactam, sulfonamide, tetracycline, quinolone, fluoroquinolone e pyrimidine in raw milk
Abstract Food quality and safety have been a concern of the world population, especially in relation to the chemical and microbiological hazards present in food. The presence of antimicrobial residues at levels above the maximum residue limit makes milk unsuitable for human consumption. In this context, the objective of this study was to analyze 184 raw milk

8. Substituting sucralose with rebaudioside A in soy foods: equivalent sweetness, physicochemical analysis, microbiological assessment and acceptance test
Abstract Stevia rebaudiana (Bert.) Bertoni contains steviol glycosides with emphasis to rebaudioside A, which presents a stronger sweet flavor, more stability, good solubility and lower bitter residual taste, which benefits its application in foods and drinks. The objective of this study was to determine the equivalent amount of rebaudioside A necessary to p

9. Evaluation of extruded corn breakfast cereal enriched with whole peach palm (Bactris gasipaes, Kunth) Flour
Abstract The present study aimed to develop extruded corn breakfast cereal enriched with whole peach palm flour. A 22 central composite rotatable design was used, and the cereal was processed in a ZKS-30 co-rotational twin-screw extruder (Werner and Pfleiderer), followed by its physicochemical, technological and microbiological characterization. The technolo
