(Pontificia Universidad Católica de Valparaíso, 2005)
Root instrumentation with an erbium:yttrium-aluminum-garnet laser: Effect on the morphology of fibroblasts
Objective: The purpose of this study was to evaluate the effect of erbium:yttrium-aluminum-garnet laser instrumentation of root surfaces on the morphology of fibroblasts from continuous lineage. Method and materials: ...
SERS mapping in langmuir-blodgett films and single-molecule detection
Plasmon-enhanced spectroscopic techniques have expanded single-molecule detection (SMD) and are revolutionizing areas such as bio-imaging and single-cell manipulation. Surface-enhanced (resonance) Raman scattering (SERS ...
Assessment of genetic damage induced by dental bleaching agents on mouse lymphoma cells by single cell gel (comet) assay
(Blackwell Publishing, 2005-10-01)
Dental bleaching is a simple and conservative procedure for aesthetic restoration of vital discoloured teeth. However, dental bleaching agents may represent a hazard to human health, especially by causing DNA strand breaks. ...
Genomic instability in non-neoplastic oral mucosa cells can predict risk during 4-nitroquinoline 1-oxide-induced rat tongue carcinogenesis
(Elsevier B.V., 2004-10-01)
4-Nitroquinotine 1-oxide (4NQO)-induced rat tongue carcinogenesis is a useful model for studying oral squamous cell carcinoma. The aim of this study was to investigate the level of DNA damage induced by 4NQO in oral mucosa ...
Industrial derivative of tallow: a promising renewable substrate for microbial lipid, single-cell protein and lipase production by Yarrowia lipolytica
(Pontificia Universidad Católica de Valparaíso, 2007)
Analysis of possible genotoxicity of the herbicide flurochloridone and its commercial formulations: Endo III and Fpg alkaline comet assays in Chinese hamster ovary (CHO-K1) cells
(Elsevier Science, 2016-02)
Cytotoxic and genotoxic effects of flurochloridone (FLC) and its formulations Twin Pack Gold® and Rainbow® were evaluated in CHO-K1 cells. Using the alkaline single-cell gel electrophoresis (SCGE) assay, we observed that ...
