1. Cetoconazol oral é indicado para o tratamento de micoses cutâneas?
O cetoconazol oral não é mais indicado como primeira linha de tratamento para infecções fúngicas. O perfil de risco-benefício do cetoconazol é desfavorável e existem outras opções mais seguras para o tratamento sistêmico das micoses cutâneas. Portanto, candidíase e dermatofitoses não são mais indicações para uso de cetoconazol oral. Além

2. 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

4. Design and Simulation of Broadband Horn Nanoantennas for Nanophotonic Applications
Abstract Optical plasmonic nanoantennas have proven useful in nanoplasmonic applications, paving the way for more efficient wireless optical communications. In this work, we propose a parametric study of a plasmonic horn nanoantenna in flat H sectorial format and beveled horn, both designed to radiate in the three wavelengths of optical communications: [850

5. Silver complexes for tuberculosis treatment: a short review
This paper is a brief review of silver complexes that have been identified as antibacterial drugs with promising use for the treatment of tuberculosis (TB). This treatment aims to cure and discontinue the transmission of the disease. The excessive and inappropriate use of drugs has jeopardized the effectiveness of antibiotics for the TB treatment, bringing b

6. Nutrients uptake by silver vase bromeliad roots
Resumo As bromélias são desejáveis como plantas de vaso devido as brácteas floridas e formato geralmente grande, colorido e exótico das folhas que formam uma cisterna. A principal função das raízes de bromélias epifíticas é a fixação no substrato, enquanto a captação de água e nutrientes é realizada principalmente pelas folhas. Porém, estud

7. Extending vase life of carnation flowers by postharvest nano silver, humic acid and Aloe Vera gel treatments
Resumo Flores de cravo (Dianthus caryophyllus cv. Dover) foram colhidas no estádio de pincel no início da manhã, pré-resfriadas a 4 °C por 6 horas e então movidas a seco para o laboratório. As flores foram pesadas e tratadas por 24 horas com nanopartículas de prata (AgNPs) a 0, 5 ou 10 ppm em baldes plásticos. Após os tratamentos de plusing, as flo

9. Convalescent plasma therapy - a silver lining for COVID-19 management?
ABSTRACT The COVID-19 pandemic has pushed the world towards social, economic, and medical challenges. Scientific research in medicine is the only means to overcome novel and complex diseases like COVID-19. To sum up the therapeutic wild-goose chase, many available antivirals and repurposed drugs have failed to show successful clinical evidence in patient rec

11. SYNTHESIS, CHARACTERIZATION, DFT MODELING AND IN VITRO ANTIMYCOBACTERIAL ACTIVITY ASSAYS OF A SILVER(I)-ISONIAZID COMPLEX
In the present work, a silver(I) complex with the antimycobacterial drug isoniazid (inh) is described. Elemental and thermogravimetric analyses confirmed a 1:1 metal:ligand ratio for the silver-isoniazid (Ag-inh) complex with molecular composition AgC6H7N3O·NO3. Infrared (IR) analysis suggests a bidentate coordination of isoniazid to silver by the nitrogen
