b-Ionone Modulates the Expression of miRNAs and Genes Involved in the Metastatic Phenotype of Microdissected Persistent Preneoplastic Lesions in Rats Submitted to Hepatocarcinogenesis
(2016)MicroRNAs (miRNAs) are post-transcriptional gene expression regulators which expression is frequently altered in hepatocellular carcinoma (HCC). b-ionone (bI) is noted for its ability to inhibit persistent preneoplastic ... -
Las babas del caracol. Una mirada en zigzag
(2016-04)Texto sobre las conexiones de rastros de dolor del pasado, la memoria y el exilio con la posibilidad de un futuro renovado. -
Backbone Flexibility Controls the Activity and Specificity of a Protein−Protein Interface: Specificity in Snake Venom Metalloproteases
(2010-07-09)Protein-protein interfaces have crucial functions in many biological processes. The large interaction areas of such interfaces show complex interaction motifs. Even more challenging is the understanding of (multi)specificity ... -

(2011-06-30)El presente artículo se propone como una disertación en torno al fenómeno del abuso sexual in fantil y el Backlash, comprendiendo a este último como un contra-movimiento social que busca legitimar diversas manifestaciones ... -
Bacteria contribute to plant secondary compound degradation in a generalist herbivore system.
(2020)Herbivores must overcome a variety of plant defenses, including coping with plant secondary compounds (PSCs). To help detoxify these defensive chemicals, several insect herbivores are known to harbor gut microbiota with ... -
Bacterial communities in residential wastewater treatment plants are physiologically adapted to high concentrations of quaternary ammonium compounds
(2023-08-28)Benzalkonium chloride (BAC) is a quaternary ammonium compound (QAC) widely used as the active ingredient of disinfectants. Its excessive discharge into wastewater is constant and in high concentrations, likely affecting ... -
Bacterial Sphingomyelinases and Phospholipases as Virulence Factors
(2016-06-15)Bacterial sphingomyelinases and phospholipases are a heterogeneous group of esterases which are usually surface associated or secreted by a wide variety of Gram-positive and Gram-negative bacteria. These enzymes hydrolyze ... -
Bacterias cultivables resistentes a oxitetraciclina durante el proceso de vermicompostaje de excretas bovinas
(2023-05-01)Introducción: A nivel mundial se han detectado bacterias con genes de resistencia al antibiótico oxitetraciclina en estiércol de vacas lecheras, sin embargo, es una práctica común utilizar este estiércol como fertilizante. ... -
Bacterias fitopatógenas

Bacterias multirresistentes a los antibióticos aisladas de niños hospitalizados de "alto riesgo"
(Revista Médica del Hospital Nacioanl de Niños Dr. Carlos Sáenz, 1978)Between January and September, 1977, 43 strains of Klebslella-Enterobac-ter, 17 of Pseudomonas and 6 of Escherlchla coli —all resistant to several drugs—were isolated from 66 children hospitalized in the National Children's ... -
Bactericidal activity of Lys49 and Asp49 myotoxic phospholipases A2 from Bothrops asper snake venom: synthetic Lys49 myotoxin II-(115-129)-peptide identifies its bactericidal region
(1998)Mammalian group-II phospholipases A2 (PLA2) of inflammatory fluids display bactericidal properties, which are dependent on their enzymatic activity. This study shows that myotoxins II (Lys49) and III (Asp49), two group-II ... -
Bactericidal and anti-endotoxic properties of short cationic peptides derived from a snake venom Lys49 phospholipase A2
(2005)The activities of short synthetic, nonhemolytic peptides derived from the C-terminal region of myotoxin II, a catalytically inactive phospholipase A2 homologue present in the venom of the snake Bothrops asper, have been ... -
