Role and quality of nurse practitioner practice: a policy issue.

Nurse practitioners (NPs) are at a crucial period in the development of their profession. The increasing demand for primary care practitioners is changing the environment in which they practice. As they face both increased opportunity and continuing opposition to independent practice, NPs must define their role in healthcare delivery and establish their capabilities.

Characterization of wheatgrass-derived barley yellow dwarf virus resistance in a wheat alien chromosome substitution line.

ABSTRACT Wheatgrass (Thinopyrum intermedium) possesses a high level of resistance to barley yellow dwarf virus (BYDV) subgroup I and subgroup II strains. A wheat line (P29), in which the 7D chromosome has been substituted with a group 7 chromosome from T. intermedium, was examined for the level of resistance to two subgroup I and two subgroup II BYDV strains.

Barley yellow dwarf virus and Cereal yellow dwarf virus Quantification by Real-Time Polymerase Chain Reaction in Resistant and Susceptible Plants.

ABSTRACT Reliable detection and quantification of barley and cereal yellow dwarf viruses (YDVs) is a critical component in managing yellow dwarf diseases in small grain cereal crops. The method currently used is enzyme-linked immunosorbent assay (ELISA), using antisera against the coat proteins that are specific for each of the various YDVs. Recently, quantitative real-time reverse-transcription polymerase chain reaction (Q-RT-PCR) has been used to detect bacterial and viral pathogens and to study gene expression.

Cultural tailoring for mammography and fruit and vegetable intake among low-income African-American women in urban public health centers.

Background: It is widely accepted that disease prevention efforts should consider cultural factors when addressing the needs of diverse populations, yet there is surprisingly little evidence that doing so enhances effectiveness. The Institute of Medicine has called for randomized studies directly comparing approaches that do and do not consider culture.

Methods: In a randomized trial, 1227 lower-income African-American women from 10 urban public health centers were assigned to either a usual care control group, or to receive a series of six women's health magazines with content tailored to each individual.

Responses to behaviorally vs culturally tailored cancer communication among African American women.

Objective: To examine whether tailored cancer communication for African American women can be enhanced by tailoring on 4 sociocultural constructs: religiosity, collectivism, racial pride, and time orientation.

Methods: In a randomized trial, participants (n=1,227) received a women's health magazine tailored using behavioral construct tailoring (BCT), culturally relevant tailoring (CRT), or both (COMBINED). Two follow-up interviews assessed responses to the magazines.
