Do Musicians with Perfect Pitch Have More Autism Traits than Musicians without Perfect Pitch? An Empirical Study por Krueger, Frank, Dohn, Anders, Garza Villarreal, Eduardo A., Heaton, Pamela, Vuust, Peter

“…Here, we determine whether individual autistic traits are present in people with AP. We quantified subclinical levels of autism traits using the Autism-Spectrum Quotient (AQ) in three matched groups of subjects: 16 musicians with AP (APs), 18 musicians without AP (non-APs), and 16 non-musicians. …”

Molecular annotation of ketol-acid reductoisomerases fromStreptomycesreveals a novel amino acid biosynthesis interlock mediated by enzyme promiscuity por Verdel Aranda, Karina, López Cortina, Susana, Hodgson, David A., Barona Gómez, Francisco

“…Moreover, both ilvC orthologues and paralogues were analysed, such that the relationship between gene duplication and functional diversification could be explored. The KARI paralogues present in S. coelicolor and Streptomyces lividans, despite their conserved high sequence identity (97%), were shown to be more promiscuous, suggesting a recent functional diversification. …”

Efficacy of DA-7218, a new oxazolidinone prodrug, in the treatment of experimental actinomycetoma produced by nocardia brasiliensis por Espinoza González, Nelly Alejandra, Welsh Lozano, Oliverio, De Torres, Noemi Waksman, Cavazos Rocha, Norma Cecilia, Ocampo Candiani, Jorge, Said Fernández, Salvador, Lozano Garza, Gerardo, Choi, Sung Hak, Vera Cabrera, Lucio

“…Two recently synthesized oxazolidinones: (R)-3-(4-(2-(2-methyltetrazol-5-yl)- pyridin-5-yl)-3-fluorophenyl)-5-hydroxymethyloxazolidin-2-one (DA-7157) and its corresponding pro-drug (R)-3-(4-(2-(2-methyltetrazol-5-yl)-pyridin-5-yl)-3-fluorophenyl)- 2-oxo-5-oxazolidinyl) methyl disodium phosphate (DA-7218), have shown very good activity against several Gram positive bacteria, including Nocardia and Mycobacterium. In the present work we evaluated the therapeutic in vivo effects of DA-7218 on Nocardia brasiliensis. …”

Quantification of nitric oxide by high‑performance liquid chromatography‑fluorometric method in subgenomic hepatitis C virus‑replicon expressing Huh7 cells upon treatment with acet... por Ríos Ibarra, Clara Patricia, Torres de la Cruz, Víctor Manuel, Ochoa Ruiz, Andrea Gabriela, Rivas Estilla, Ana María

“…As nitric oxide (NO) expression levels are lower in hepatocytes compared with other cell types, it is difficult to quantify this compound via Griess assay. The aim of the present study was to quantify NO concentration in the cell culture medium from a subgenomic hepatitis C virus (HCV)‑replicon expressing Huh‑7 cell system using a high‑performance liquid chromatography (HPLC)‑fluorescence detector in the presence or absence of acetylsalicylic acid (ASA) treatment. …”

Enzymatic Potential of Native Fungal Strains of Agave Residues por Contreras Hernández, Maria Gorety, Aréchiga Carvajal, Elva Teresa, Moreno Jiménez, Martha Rocio, González Herrera, Silvia Marina, López Miranda, Javier, Prado Barrágan, Lilia Arely, Rutiaga Quiñones, Olga Miriam

“…Our previous studies showed that the expression of orexin was decreased in mice carrying null-mutations of the transcription factor early B-cell factor 2 (ebf2) and that the promoter region of the prepro-orexin (Hcrt) gene contained two putative ebf-binding sites, termed olf‑1 sites. In the present study, a minimal promoter region of the murine Hcrt gene was identified, which was able to drive the expression of a luciferase reporter gene in the human 293 cell line. …”
