Living with pain: narrating an ideological position toward healthcare.

The purpose of this study is to demonstrate how individual experiences shape ideologies toward healthcare. To demonstrate, we analyze conversational narrative data about health and healthcare between a dominant Spanish-speaking Mexican immigrant woman, Maria, and the researcher, Caroline. Findings demonstrate that Maria's narrative about her experience receiving healthcare for a knee injury reveals her ideological stance toward healthcare in both the United States and Mexico.

The bactericidal effect of silver nanoparticles.

Nanotechnology is expected to open new avenues to fight and prevent disease using atomic scale tailoring of materials. Among the most promising nanomaterials with antibacterial properties are metallic nanoparticles, which exhibit increased chemical activity due to their large surface to volume ratios and crystallographic surface structure. The study of bactericidal nanomaterials is particularly timely considering the recent increase of new resistant strains of bacteria to the most potent antibiotics.

Interaction of silver nanoparticles with HIV-1.

The interaction of nanoparticles with biomolecules and microorganisms is an expanding field of research. Within this field, an area that has been largely unexplored is the interaction of metal nanoparticles with viruses. In this work, we demonstrate that silver nanoparticles undergo a size-dependent interaction with HIV-1, with nanoparticles exclusively in the range of 1-10 nm attached to the virus.
