Cytotoxicity and bioactivity of various pulpotomy materials on stem cells from human exfoliated primary teeth.
2017
Aims To investigate the cytotoxicity and bioactivity of several pulpotomy materials: Biodentine (Septodont, Saint-Maur-des-Fosses, France) MTA (Angelus, Londrina, PR, Brazil), Theracal LC (Bisco Inc., Schamburg, IL, USA) and IRM (Dentsply DeTrey GmbH, Konstanz, Germany), after contact with stem cells isolated from human exfoliated primary teeth (SHEDs). Methodology SHEDs were cultured in the presence of the eluates of various pulpotomy materials for 24, 48 and 72 h. Cell viability was determined by mitochondrial dehydrogenase enzymatic (MTT) assay. Apoptosis and changes in cell phenotype were evaluated by flow cytometry. Also, an in vitro scratch wound-healing assay was used to determine th…
Synthesis of vanillin in water by TiO2 photocatalysis
2012
Abstract The photoproduction of vanillin is studied in aqueous medium starting from trans-ferulic acid, isoeugenol, eugenol or vanillyl alcohol by using both commercial and home prepared TiO2 samples as photocatalysts and batch Pyrex photoreactors. The photo-oxidation at room temperature of these compounds produces vanillin with a selectivity ranging from 1.4 to 21 mol% with respect to the converted substrate. An investigation on the intermediates was performed in the case of trans-ferulic acid; for this substrate the most important intermediates were homovanillic acid, vanillyl mandelic acid, trans-caffeic acid, formic acid, acetic acid, and oxalic acid. The carbon mass balance, including …
Villamalea. 1900-1939. Estudio sobre una comunidad rural de La Mancha. Del caciquismo a la aparición de las organizaciones de clase.
1980
El objeto de la Tesis Doctoral es el estudio de una comunidad rural en La Mancha, Villamalea (Albacete) durante el período 1900-1939. El interés por el estudio de Villamalea tiene su base en el fuerte desarrollo político y sindical, como consecuencia de la conciencia política y social, que alcanza su mayor expresión en la década de los años 60 y 70 del siglo XX. El alto nivel de conflictividad con el régimen del general Franco, el arraigo y la extensión de la conciencia de clase de los vecinos, la forma original con que se enfrentaron los problemas económicos y la crisis de la agricultura, las alternativas planteadas a la situación existente y otros hechos acaecidos en la década de los años…
Survival Value and a Robust, Practical, Joyless Individualism: Thomas Nixon Carver, Social Justice, and Eugenics
2017
The aim of this paper is to provide a compressive assessment of Thomas Nixon Carver's thought—from his early formative years in the 1880s to his post WWII career as a journalist and pamphleteer. The main (albeit not exclusive) focus of this paper will be on the theoretical and philosophical coordinates of Carver's “new liberalism”—his own definition—and how this broad vision was intrinsically connected with an explicitly hierarchical and eugenic approach to human nature. Just as important, what follows is also an attempt to increase our general understanding of the extent in which eugenic considerations permeated the realm of political economy during the first decades of the last century an…

Der Spur auf der Spur. Sur les traces de la trace
2016
Hinter dem scheinbar einfachen lexikalischen Gewand der »Spur« verbirgt sich eine überraschende Komplexität: Was ist eigentlich eine Spur? Was sind ihre typischen Merkmale? Wodurch unterscheidet sie sich von Abdruck, Zeichen und Indiz? Die Beiträge des vorliegenden Bandes reflektieren den Spurbegriff aus deutsch-französischer sowie aus interdisziplinärer Perspektive. Zu Wort kommen Philosophie, Literatur, Geschichte, Archäologie, Kunstgeschichte, Urbanistik, Kulturwissenschaft und Psychoanalyse.

Transfer of volatile phenols at oak wood/wine interface in a model system
2006
Abstract In order to assess the influence of wood on the concentration of aroma compounds during ageing of wine, the transfer of volatile phenols including 4-ethylphenol, eugenol and a homologous series of guaiacols from wine to oak wood were studied in a model system at 10°C. At equilibrium most of the volatile phenols adsorbed in the wood. The results display that the amounts adsorbed depend on the nature of the volatile phenols and the botanical origin of oak wood.
Development and characterization of essential oil component-based polymer films: a potential approach to reduce bacterial biofilm
2013
The development of new polymeric materials aimed to control the bacterial biofilm appears to be an important practical approach. The goal of the present study was to prepare and characterize poly(ethylene-co-vinyl acetate) copolymer (EVA) films containing citronellol, eugenol, and linalool and evaluate their efficiency on growth and biofilm formation of Listeria monocytogenes, Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Pseudomonas aeruginosa in monospecies and dual species. The results showed that the addition of oil components influenced the elastic modulus (15 % decrease), the tensile stress (30 % decrease), the elongation at break (10 % increase), and the co…
A HS-SPME-GC-MS analysis of IR heated wood: Impact of the water content on the depth profile of oak wood aromas extractability
2013
http://www.sciencedirect.com/science/article/pii/S0963996913003736; International audience; Controlled and reproducible IR heat treatments were applied to oak wood surfaces in order to establish a depth-profiled picture of the extractability of volatile compounds, with particular emphasis on the impact of the initial water content. Headspace-solid phase microextraction-gas chromatography coupled to mass spectrometry (HS-SPME-GC-MS) has been used to compare the concentrations of six aroma compounds (vanillin, furfural, eugenol; guaiacol and cis- and trans-whisky lactones) in hydroalcoholic extracts of series of slices representative of the first 8 mm of the wood facing the IR source.
