Virus and non-coding RNAs: stars in the host-virus interaction game

In the past few years, noncoding RNAs (ncRNAs) have emerged as key modulators of the transcriptional and post-transcriptional control of a variety of cellular processes such as development, signaling, homeostasis and oncogenesis. Like their host cells, many viruses produce ncRNAs.

Larvicidal, molluscicidal and nematicidal activities of essential oils and compounds from Foeniculum vulgare

Plant-based products, namely essential oils (EOs), are environmentally friendly alternatives for the control of disease vectors, hosts and/or parasites. Here, we studied the general toxicity and biopesticidal potential of EOs and phenylpropanoids from Foeniculum vulgare var. vulgare (bitter fennel), a perennial plant well adapted to temperate climates.

Iron oxide colloids: a comparative study of different surfactants

Iron oxide nanoparticles are having been extensively investigated for several biomedical applications such as hyperthermia and magnetic resonance imaging. However, one of the biggest problems of these nanoparticles is their aggregation. Taking this into account, in this study the influence of three different surfactants (oleic acid, sodium citrate and Triton X-100) each one with various concentrations in the colloidal solutions stability was analyzed by using a rapid and facile method, the variation in the optical absorbance along time.
