A Conceptual Framework for Barriers to the Recruitment and Retention of Rural CVD Participants in Behavior Intervention Trials.

Background: Rural residents diagnosed with cardiovascular disease (CVD) or with CVD-related risks are underrepresented in behavioral intervention trials based on an extensive review of published studies. The low participation rate of rural residents weakens both the internal and external validity of published studies. Moreover, compared to urban residents, limited research exists to describe the unique barriers that limit the participation of rural residents in behavioral intervention trials.

Examination of cross-antigenicity of acetylcholinesterase and butyrylcholinesterase using anti-acetylcholinesterase antibodies.

Acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) share a high degree of homology and overlap in several biochemical properties. This study aimed to compare and contrast the antigenic reactivity of AChE and BuChE with several polyclonal antibodies. We have performed a detailed analysis of AChE and BuChE enzymatic activities with different substrates and different inhibitors.
