Saccharomyces eubayanusandSaccharomyces uvarumassociated with the fermentation ofAraucaria araucanaseeds in Patagonia
2014
Mudai is a traditional fermented beverage, made from the seeds of the Araucaria araucana tree by Mapuche communities. The main goal of the present study was to identify and characterize the yeast microbiota responsible of Mudai fermentation as well as from A. araucana seeds and bark from different locations in Northern Patagonia. Only Hanseniaspora uvarum and a commercial bakery strain of Saccharomyces cerevisiae were isolated from Mudai and all Saccharomyces isolates recovered from A. araucana seed and bark samples belonged to the cryotolerant species Saccharomyces eubayanus and Saccharomyces uvarum. These two species were already reported in Nothofagus trees from Patagonia; however, this …
Desarrollo y aplicación de sistemas rápidos para la detección, indentificación y caracterización de levaduras alterantes de alimentos.
2006
La importancia de las levaduras se conoce desde hace mucho tiempo y con el desarrollo de la industria, se utilizan no sólo para la elaboración de un gran número de productos fermentados (cerveza, vino, quesos y embutidos), sino también para la producción de antibióticos, vitaminas, enzimas, etc. Sin embargo, las levaduras tienen también un aspecto negativo, debido a su potencial como alterantes de alimentos, lo que implica pérdidas económicas importantes para las industrias. En el presente trabajo se abordan aspectos relacionados con la identificación y caracterización molecular de algunas de las especies típicamente alterantes, pertenecientes a los géneros Debaryomyces, Zygosaccharomyces, …
Sparse Deconvolution Using Support Vector Machines
2008
Sparse deconvolution is a classical subject in digital signal processing, having many practical applications. Support vector machine (SVM) algorithms show a series of characteristics, such as sparse solutions and implicit regularization, which make them attractive for solving sparse deconvolution problems. Here, a sparse deconvolution algorithm based on the SVM framework for signal processing is presented and analyzed, including comparative evaluations of its performance from the points of view of estimation and detection capabilities, and of robustness with respect to non-Gaussian additive noise.

Effects of Polyphenol, Measured by a Biomarker of Total Polyphenols in Urine, on Cardiovascular Risk Factors After a Long-Term Follow-Up in the PREDI…
2016
Several epidemiological studies have shown an inverse association between the consumption of polyphenol-rich foods and risk of cardiovascular diseases. However, accuracy and reliability of these studies may be increased using urinary total polyphenol excretion (TPE) as a biomarker for total polyphenol intake. Our aim was to assess if antioxidant activity, measured by a Folin-Ciocalteu assay in urine, is correlated with an improvement in cardiovascular risk factors (blood pressure and serum glucose, cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride concentrations) in an elderly population at high risk. A longitudinal study was performed with 573 participants (aged 67.3 ± 5.9) f…
Cinceles en la Edad del Bronce italiana: aspectos tecnológicos y tipológicos
2010
Bronze chisels are tools used “à percussion posée”; this means they need a minimum length and some functional parts (tang, body, blade); they could have a handle of perishable material and they were used with a hammer to work wood, bronze and other materials. Chisels can be classified following their functional parts; the first element is the shape (rod or socketed chisel); the second one is body section; the third one is tang section. Chronology and distribution of every type were identified to obtain a general view of this class of tools during the Italian Bronze Age.
Búsqueda de nuevos ingredientes bioactivos en obesidad para el diseño de nuevos alimentos funcionales, en base a la demanda del consumidor
2015
La innovación tecnológica en materia de salud ha sido un campo ampliamente estudiado y sigue siendo un foco de interés económico reiterado y prioritario. La alimentación es uno de los hábitos que más repercusión tienen en el estado de salud y en la prevención de determinadas enfermedades lo que influye cada vez más en los hábitos de compra de los consumidores (Niva M., 2007, Bech-Larsen T et al., 2007, Jones PJ et al., 2007, Van Kleef E et al., 2002). Un trastorno de la alimentación puede generar obesidad y con ello el desarrollo de múltiples complicaciones asociadas a la misma. En los últimos años, la Organización Mundial de la Salud (WHO., 2014 y 2015) ha venido alertando de la gran crisi…

Response to long-term NaHCO3-derived alkalinity in model Lotus japonicus Ecotypes Gifu B-129 and Miyakojima MG-20: transcriptomic profiling and physi…
2014
The current knowledge regarding transcriptomic changes induced by alkalinity on plants is scarce and limited to studieswhere plants were subjected to the alkaline salt for periods not longer than 48 h, so there is no information availableregarding the regulation of genes involved in the generation of a new homeostatic cellular condition after long-termalkaline stress.Lotus japonicusis a model legume broadly used to study many important physiological processes includingbiotic interactions and biotic and abiotic stresses. In the present study, we characterized phenotipically the response toalkaline stress of the most widely usedL. japonicusecotypes, Gifu B-129 and MG-20, and analyzed global t…
