“…Iron oxide nanoparticles (IONP) are recognized by their high chemical and thermal stabilities, low cost, very high area-to-volume and area-to-weight ratios, and superparamagnetic behaviour. These attributes are valuable for biomedical applications [ 83 , 84 ]. Accordingly, IONPs have been explored as drug delivery systems to increase drug effectiveness and reduce therapeutic drug concentrations [ 36 ].…”

Metal Nanoparticles to Combat Candida albicans Infections: An Update

et al. 2023

Candidiasis is an opportunistic mycosis with high annual incidence worldwide. In these infections, Candida albicans is the chief pathogen owing to its multiple virulence factors. C. albicans infections are usually treated with azoles, polyenes and echinocandins. However, these antifungals may have limitations regarding toxicity, relapse of infections, high cost, and emergence of antifungal resistance. Thus, the development of nanocarrier systems, such as metal nanoparticles, has been widely investigated. Metal nanoparticles are particulate dispersions or solid particles 10–100 nm in size, with unique physical and chemical properties that make them useful in biomedical applications. In this review, we focus on the activity of silver, gold, and iron nanoparticles against C. albicans. We discuss the use of metal nanoparticles as delivery vehicles for antifungal drugs or natural compounds to increase their biocompatibility and effectiveness. Promisingly, most of these nanoparticles exhibit potential antifungal activity through multi-target mechanisms in C. albicans cells and biofilms, which can minimize the emergence of antifungal resistance. The cytotoxicity of metal nanoparticles is a concern, and adjustments in synthesis approaches or coating techniques have been addressed to overcome these limitations, with great emphasis on green synthesis.

“…La CHX posee un efecto inhibidor de las MMP que mejora la estabilidad de la unión resina-dentina a largo plazo (16). Se ha informado que el uso de CHX al 2% como imprimación terapéutica antes de la infiltración de los monómeros de resina estabiliza la unión resina-dentina debido a la inhibición de la actividad de las MMP (17).…”

El tratamiento de la dentina como paso previo al procedimiento de adhesión tiene como propósito mejorar las condiciones del sustrato mejorando la fuerza de unión entre la superficie dentaria y el material de restauración, promoviendo mayor longevidad y estabilidad de la restauración. El objetivo del estudio fue realizar una revisión de la literatura que describe las propiedades de diferentes agentes acondicionantes de la dentina. Se realizó una revisión de la literatura incluyendo trabajos publicados entre el 2014 a 2020, de bases de datos médicas como PubMeb, SciELO y ScienceDirect; en idioma inglés, español y portugués. Se seleccionaron un total de 20 artículos que cumplían los criterios de inclusión. Se ha identificado en la literatura el uso de diversos agentes pre tratamiento de la dentina, principalmente agentes químicos como el hipoclorito de sodio, clorhexidina, el ácido etilenodiaminatetraacético (EDTA), las nanopartículas metálicas y las técnicas mecánicas como la abrasión por aire con óxido de aluminio y bicarbonato de sodio.

“…Paper discs of 6 mm of diameter with 20 µL of the supernatants (metabolites) were transferred to plates individually covered with P. ananatis strains, CMPC 40 and CMPC 105. The plates were incubated at 30 °C for 48 h and inhibition halos was evaluated (Bauer et al, 1966;Rodrigues et al, 2019). After determining the culture medium and time of growth in which there was greater antibacterial activity, the samples containing the metabolites produced by actinobacteria strains were lyophilized and resuspended in 5 mL of sterile deionized water.…”

Biocontrol potential of actinobacteria against Pantoea ananatis, the causal agent of maize white spot disease

et al. 2023

Pantoea ananatis is the causal agent of maize white spot, a foliar disease responsible for significant maize yield reduction worldwide, especially in Brazil. In general, the maize foliar diseases control involves the adoption of resistant genotypes and pesticides application. However, the use of agrochemicals can significantly cause increase production costs, damage to human health and negative environmental impacts. In this sense, the use of biological control agents has been considered among the most promising eco-friendly technologies for sustainable agriculture. Actinobacteria, particularly of Streptomyces genus, has been widely recognized as agroindustrially important microorganism due to its potential in producing diverse range of secondary metabolites, including antibiotics and enzymes. Thus, the aim of this work is to characterize and to evaluate the potential of soil actinobacteria for P. ananatis control. We observed that 59 actinobacteria strains (85%) exhibited proteolytic or chitinolytic activity. Only the strains Streptomyces pseudovenezuelae ACSL 470, that also exhibited high proteolytic activity, S. novaecaesareae ACSL 432 and S. laculatispora ACP 35 demonstrated high or moderate antagonist activity in vitro against P. ananatis. Temporal analysis of metabolites produced by these strains growth in different liquid media indicated greater antibacterial activity at 72 h. In this condition, chromatographic and mass spectrometry analysis revealed that S. pseudovenezuelae ACSL 470 strain produced neomycin, an aminoglycoside antibiotic that displayed high bactericidal activity in vitro against P. ananatis. This is the first report of actinobacteria acting as potential microbial antagonists for P. ananatis control. Further studies are needed to determine the control efficacy of maize white spot disease by Streptomyces strains or their metabolites in greenhouse and field conditions.
