Reactions of excited states of phenoxazin-3-one dyes with amino acids
(Wiley Blackwell Publishing, Inc, 2005-07)
The interaction with amino acids of the excited states of the N-oxide resazurin and its deoxygenation product resorufin, has been studied in aqueous solution at pH 7.5. Steady-state and time-resolved studies show that the ...
Photoreaction and photopolymerization studies on phenoxazin dyes/diphenyliodonium chloride salt
(Elsevier Science Sa, 2007-04)
The photophysics and photochemistry of the dyes resazurin (Rz) and resorufin (Rf) in absence and presence of diphenyliodonium chloride (DPIC) were investigated in water at pH 10. The dye/DPIC combination undergoes photoreaction ...
Evaluation of fluoromycobacteriophages for detecting drug resistance in Mycobacterium tuberculosis
(American Society for Microbiology, 2011-05)
We tested a new method for detecting drug-resistant strains of Mycobacterium tuberculosis that uses a TM4 mycobacteriophage phAE87::hsp60-EGFP (EGFP-phage) engineered to contain the gene encoding enhanced green fluorescent ...
Nanostructured paper-based platform for phenylalanine neonatal screening by LED-induced fluorescence
(Royal Society of Chemistry, 2020-03)
In this work, a novel paper-based analytical device (PAD) coupled to LED-induced fluorescence (LIF) detection (fPAD) for the rapid, selective, and sensitive quantification of phenylalanine (Phe) in neonatal samples was ...
Antimicrobial activity of Terpenes against slime producing and non producing Staphylococci
(Instituto de Investigación de las Ciencias Exactas Físicas y Naturales, 2010-01)
Staphylococcus aureus, responsible of several diseases in humans and animals, produce virulence factors like an extracelullar polysacharide or “slime”. Methicillin resistant S. aureus (MRSA) is able to resist -lactamic ...

Dealing with biofilms of Pseudomonas aeruginosa and Staphylococcus aureus: In vitro evaluation of a novel aerosol formulation of silver sulfadiazine
(Elsevier, 2020-02)
The risk of infection of skin and soft tissue chronic wounds by gram-negative and gram-positive pathogens growing in biofilms is a major health-care concern. In this study we test a formulation of silver sulfadiazine, ...
Modulation of Fatty Acids and Interleukin-6 in Glioma Cells by South American Tea Extracts and their Phenolic Compounds
(Lawrence Erlbaum Assoc Inc-taylor & Francis, 2018-02-21)
Dietary phenolic compounds are plant metabolites with beneficial effects on the central nervous system. Thus, our aim was to identify anti-inflammatory compounds from South American plants on glia, which regulates neuro-immune ...
Actividad moduladora in vitro de extractos acuosos de plantas americanas sobre la toxicidad inducida por clorpirifos en esplenocitos murinosIn vitro modulating activity of aqueous extracts from american plants on chlorpyrifos-induced toxicity on murine splenocytes
(Universidad Nacional de Córdoba. Facultad de Ciencias Médicas, 2017-12)
Clorpirifos es un pesticida altamente tóxico, que puede producir inmunotoxicidad con efectos deletéreos sobre la salud a nivel mundial. Por otro lado, las plantas americanas pueden tener derivados con actividad protectora ...
Bedaquiline and linezolid MIC distributions and epidemiological cut-off values for Mycobacterium tuberculosis in the Latin American region
(Oxford University Press, 2019-02)
Objectives To describe the distributions of bedaquiline and linezolid MIC values for the Mycobacterium tuberculosis WT population and to define the corresponding epidemiological cut-offs (ECOFFs) in three Latin American ...
