Measurement of lipoxygenase activity in crude and partially purified potato extracts

Two assay systems, one a spectrophotometric assay at 234 nm, the other based on the oxygen electrode, were compared as methods for the routine analysis of lipoxygonase activity in crude and partially purified potato extracts. The spectrophotometric assay was unsuitable for the analysis of crude extracts and only gave meaningful results under very restricted reaction conditions. The oxygen electrode provided a reliable method for routine analysis of lipoxygenase activity.     

Community Perceptions of Hospitals and Shared Physical Space: A Qualitative Study

In addition to providing critical medical services to communities, hospitals are also forces of broader change when seen from the perspective of neighborhood development. Over the past few decades the obligation on the part of U.S. nonprofit hospitals to positively impact the communities in which they are located has become entrenched in both U.S. tax law and the practices of many hospitals. This article presents findings from a grounded theory qualitative study of the relationship between a non-profit children’s hospital in Columbus, Ohio, and the neighborhood in which it is located. Based on in-depth interviews with local residents and community leaders, findings suggest that community members often interpret distance, safety, and transportation in different, and often counter-intuitive ways. Drawing upon literature from medical geography and sociology, the authors argue that hospitals may benefit from working closely with community members to determine how space is understood and constructed when planning community health interventions.
