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. In particular, the narrative reflects an ideological position in which medical providers neglect patients and strip them of agency in making choices about their own healthcare. Cultural competence, then, is not only about gaining knowledge of patients' cultural groups but also about understanding how patients' life experiences shape them as autonomous individuals with socially constructed attitudes toward healthcare.

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. The regular spatial arrangement of the attached nanoparticles, the center-to-center distance between nanoparticles, and the fact that the exposed sulfur-bearing residues of the glycoprotein knobs would be attractive sites for nanoparticle interaction suggest that silver nanoparticles interact with the HIV-1 virus via preferential binding to the gp120 glycoprotein knobs. Due to this interaction, silver nanoparticles inhibit the virus from binding to host cells, as demonstrated in vitro.
