Development and In Vitro Validation of Antibacterial Paints Containing Chloroxy...
Querido, MM; Paulo, I; Hariharakrishnan, S; Rocha, D; Barbosa, N; Gonçalves, D; Dos Santos, RG; Bordado, JM; Teixeira, JP; Pereira, CCThe establishment of self-disinfecting surfaces is an important method to avoid surface contamination. Recently, paints with antimicrobial properties have been developed to be applied on different surfaces, avoiding contamination with pathogens. In this work, self-disinfecting paints containing Chloroxylenol (CLX), Terpineol (TRP), and a mixture of both substances were developed. The goal was to evaluate and va...
In Vitro Cyto-and Genotoxicity Assessment of Antibacterial Paints with Triclosa...
Querido, MM; Rosário, F; Bessa, MJ; Mendes, F; Teixeira, JC; Teixeira, JP; Pereira, CCSurfaces with antimicrobial properties are gaining notoriety as an efficient method to avoid surface contamination. Self-disinfecting paints are a promising strategy towards cleaner indoor environments by preventing the colonization of walls with microorganisms. However, its widespread use needs an appropriate toxicological safety evaluation due to the potential for biological disturbance associated to its bioc...
Self-Disinfecting Paints with the Natural Antimicrobial Substances: Colophony a...
Querido, MM; Paulo, I; Hariharakrishnan, S; Rocha, D; Barbosa, N; Galhano dos Santos, R; Bordado, JM; Teixeira, JP; Pereira, CCThe risk of infection arising from indirect sources—namely, contaminated surfaces—has been proved, particularly in healthcare facilities. In the attempt to minimize this problem, innumerable research projects involving the development of surfaces with self-disinfecting properties are being conducted. In this work, wall-paints with self-disinfecting properties were developed with the scope of being applied in en...
Self-disinfecting surfaces and infection control
Querido, MM; Aguiar, L; Neves, P; Pereira, CC; Teixeira, JPAccording to World Health Organization, every year in the European Union, 4 million patients acquire a healthcare associated infection. Even though some microorganisms represent no threat to healthy people, hospitals harbor different levels of immunocompetent individuals, namely patients receiving immunosuppressors, with previous infections, or those with extremes of age (young children and elderly), requiring ...
Optimization of the harvesting and freezing conditions of human cell lines for ...
Bessa, MJ; Brandão, F; Querido, MM; Costa, C; Pereira, CC; Valdiglesias, V; Laffon, B; Carriere, M; Teixeira, JP; Fraga, SThe comet assay is a commonly used method for in vitro and in vivo genotoxicity assessment. This versatile assay can be performed in a wide range of tissues and cell types. Although most of the studies use samples immediately processed after collection, frozen biological samples can also be used. The present study aimed to optimize a collection and freezing protocol to minimize the DNA damage associated with th...
Indoor exposure to bioaerosol particles: levels and implications for inhalation...
Madureira, J; Aguiar, L; Pereira, C; Mendes, A; Querido, MM; Neves, P; Teixeira, JPChildren spend most of their time inside schools and bioaerosol particles are part of their everyday environment. Although bioaerosol particles are considered to be a potential risk factor for various health concerns, information concerning the indoor exposures and inhalation doses is still limited. This study aimed (i) to quantify bacterial and fungal particles levels in indoor and outdoor air of public primar...
