Biología y ecología de la merluza bajacaliforniana, Merluccius angustimanus Garman, 1899, en la costa occidental de baja california sur, México por Balart Páez, Eduardo Francisco

“…To that purpose representative samples of the hake, the notebooks of the fishery cruises developed between 1987 and 1995, and the facilities to perform the laboratory and computer analysis were available. It is concluded that M. angustimanus is taxonomically and ecologically discernable from M. productus, a hake that shares the northern range of its distribution. …”

Contradicciones éticas de las responsabilidades sociales en la bibliotecología por Muela Meza, Zapopan Martín

“…It shows evidences on the fact that the professionals of the documental information (PDIs, included librarians) which works were analized that they only show an analysis of the ethical phenomenon exclusively from philosophy, or from a social science, or from philosophy and combined with a social science, but in all the cases none of them include an analysis from the natural sciences such as biology or neuropsicology. …”

Inhibición de la replicación y expresión de un replicón subgenómico del virus de la hepatitis c, con RNA’S de interferencia por Elizondo González, Regina

“…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 por Leal Guerra, Clara Susana

“…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). …”
