Removal of Waterborne Viruses by Tetrahymena pyriformis Is Virus-Specific and Coincides with Changes in Protist Swimming Speed
<p>Biological treatment of waterborne viruses, specifically grazing of viruses by protists, can enhance microbial water quality while avoiding the production of toxic byproducts and high energy costs. However, tangible ...
Global metabolic profiling of Arabidopsis polyamine oxidase 4 (AtPAO4) loss-of-function mutants exhibiting delayed dark-induced senescence.
Early and more recent studies have suggested that some polyamines (PAs), and particularly spermine (Spm), exhibit anti-senescence properties in plants. In this work, we have investigated the role of Arabidopsis Polyamine ...
La complejidad de lo simple: la célula bacteriana
El famoso entomólogo y padre de la sociobiología Edward O. Wilson, de la Universidad de Harvard, escribió el siguiente párrafo para finalizar su libro autobiográfico Naturalist (1994, Island Press, Washington, p. 364): "Si ...
Sampling the conformational energy landscape of a hyperthermophilic protein by engineering key substitutions
<p>Proteins exist as a dynamic ensemble of interconverting substates, which defines their conformational energy landscapes. Recent work has indicated that mutations that shift the balance between conformational substates ...

Potencial biotecnològic del cultiu de cèl·lules vegetals per a l'obtenció de productes farmacèutics
Plants produce a peculiar group of natural products, particular to the plant kingdom, the secondary metabolites, which are very numerous and structurally diverse. Provided that plant cells can grow 'in vitro', their culture ...
Whole-Genome Sequencing and Comparative Genomics of Three Helicobacter pylori Strains Isolated from the Stomach of a Patient with Adenocarcinoma
Helicobacter pylori is a common pathogen associated with several severe digestive diseases. Although multiple virulence factors have been described, it is still unclear the role of virulence factors on H. pylori pathogenesis ...
The importance of the age when evaluating mercury pollution in fishes: the case of Diplodus sargus (Pisces, Sparidae) in the NW Mediterranean
The aim of this study was to analyse the concentration of mercury (Hg) in the muscle of a common littoral, omnivorous fish such as the white seabream, Diplodus sargus, and to evaluate its relationship with the age and size ...
Optimization of a quality model for CCA industrial impregnation of Pinus radiata D. Don agricultural fencing stakes
Impregnation of agricultural fencing stakes (Pinus radiata D. Don) using wood preservative solutions, like chromated copper arsenate (CCA-C), a water soluble salt, to protect them from decay and insect damage was investigated ...
