Ibero–American Consensus on Low- and No-Calorie Sweeteners: Safety, Nutritional Aspects and Benefits in Food and Beverages
Publicado 2018“…The conclusions of this Consensus were: (1) LNCS are some of the most extensively evaluated dietary constituents, and their safety has been reviewed and confirmed by regulatory bodies globally including the World Health Organisation, the US Food and Drug Administration and the European Food Safety Authority; (2) Consumer education, which is based on the most robust scientific evidence and regulatory processes, on the use of products containing LNCS should be strengthened in a comprehensive and objective way; (3) The use of LNCS in weight reduction programmes that involve replacing caloric sweeteners with LNCS in the context of structured diet plans may favour sustainable weight reduction. …”

Inhibición de la replicación y expresión de un replicón subgenómico del virus de la hepatitis c, con RNA’S de interferencia
Publicado 2008“…A Huh-7-VHC replicon cell (cellular line that expresses a stable subgenomic replicon of HCV) was used; it was transfected, individually and combined with 3 selected siRNAs against diverse regions of the viral gene NS5b; then inhibition of the polymerase viral expression and the replication of the HCV genome was analyzed. The cells that were treated with the siRNA “A” presented a higher inhibition of the viral RNA levels during the 6 days post-transfection with inhibitions of 86% and 88% with 100 and 200 nM. …”

Regulación de la expresión de genes involucrados en la producción de compuestos de azufre en Saccharomyces cerevisiae
Publicado 2011“…In the presence of worts with low level of nutrients nitrogen, strain 820 downregulated genes that favor the incorporation of sulfur to carbon skeletons (MET6, MET13, MHT1) and at the same time over expressed genes related to the input of sulfate into the cell generating sulfur (MET3, MET2) in the other hand, strain 790 upregulated the way of balance in the production of AdoMet / methionine (MHT1 gene), without having an effect in any other gene involved. These results were confirmed by using qPCR, analyzing 18 genes total. 820 under the presence of low nitrogen compounds (wort1) was not able to adjust their genetic machinery for the incorporation of sulfur to carbon skeletons, in the other hand under the presence of wort rich in nitrogen compounds (wort 2) regulated its genetic machinery, expressing more genes involved in the transsulfuration pathway (CYS4) favored by the incorporation of serine in the way. 790 behaved differently, was able to adjust their genetic machinery in the presence of low content of nitrogen compounds by activating genes via transsulfuration (CYS4, SER2) as well genes by the incorporation of sulfur for methionine production and S-adenosylmethionine remethylation (MET6, MET13, MHT1). …”
