Cryonegative staining of macromolecular assemblies.
Methods Enzymol
January 2011
Department of Chemistry, Institute for Macromolecular Assemblies, City University of New York, City College Campus, New York, USA.
Article Synopsis
- Cryoelectron microscopy (cryo-EM) combined with single-particle reconstruction allows for detailed study of biological structures at molecular resolution, but low signal-to-noise ratio (SNR) in electron micrographs necessitates improvement methods.
- A new technique called cryonegative staining enhances SNR at the specimen preparation stage while keeping samples frozen and hydrated, offering two procedures: one using an ammonium molybdate contrasting agent and another utilizing a carbon-sandwich method with uranyl compounds.
- Both cryonegative staining methods maintain sample hydration and improve SNR significantly compared to conventional methods and provide examples of the data quality achievable with these techniques, along with a discussion on their technical background and limitations.
Perceived discrimination among severely disadvantaged people with HIV infection.
Public Health Rep
June 2007
Sophie Davis School of Biomedical Education, City University of New York, 138th St. and Covent Ave., City College Campus, New York, NY 10031, USA.
Objectives: Studies continue to document that people with human immunodeficiency virus (HIV) experience discrimination in their interactions with the health-care system, which can have negative implications for maintaining continuity in care and outcomes. We explored the patient characteristics associated with perceived discrimination and whether these experiences are associated with health-care system quality ratings in a survey of severely disadvantaged people with HIV who are at great risk of inconsistent access to appropriate health care.
Methods: Five hundred and twenty-three participants were recruited from temporary housing facilities for people with HIV in the New York City area and administered a survey using audio computer-assisted self-interviewing technology.
Does patient-provider racial/ethnic concordance influence ratings of trust in people with HIV infection?

Despite widely available and effective treatments, there are racial/ethnic disparities in HIV-related mortality rates. The reason for inadequate HIV/AIDS management among minority populations is not fully understood, however recent research indicates that patients rate the quality of their health care higher if they are racially/ethnically concordant with their providers. As trust plays prominently on health care ratings, we examined whether racial/ethnicity concordance was associated with two dimensions of trust, trust in the provider and mistrust in the health care system, in 380 HIV infected people New York City.
