We aimed to understand the distribution of Escherichia coli in poultry and to reveal the virulence factors, the drug resistance and molecular epidemic regularity and characteristics of isolate strains from 6 provinces in China and to complete the characteristics of E. coli for the risk assessment. A total of 87 E. coli isolates were analyzed with 7 virulence genes by PCR drug sensitivity test i...

OBJECTIVE The purpose of the observational study was to determine whether interviewer race influences food frequency questionnaire (FFQ) reporting accuracy in a Deep South, largely African American cohort. METHODS A secondary analysis was conducted to investigate the influence of interviewer race on energy reporting of 319 African Americans who participated in the Mississippi Communities for ...

BACKGROUND Moving from postgraduate training into independent practice represents a major transition in physicians' professional life. Little is known about how Swiss primary care graduates experience such a transition. The aim of this study was to explore the extent to which primary care physicians who recently set up private practice felt prepared to work as independent practitioners. METHO...

OBJECTIVES The purpose of this study was to test the feasibility of an electronic nursing record system for perinatal care that is based on detailed clinical models and clinical practice guidelines in perinatal care. METHODS THIS STUDY WAS CARRIED OUT IN FIVE PHASES: 1) generating nursing statements using detailed clinical models; 2) identifying the relevant evidence; 3) linking nursing state...

OBJECTIVE The aim of this study was to present our perspectives on healthcare information analysis at a conceptual level and the lessons learned from our experience with the development of a terminology-based enterprise electronic nursing record system - which was one of components in an EMR system at a tertiary teaching hospital in Korea - using an object-oriented system analysis and design co...

Volume-based registration (VBR) is the predominant method used in human neuroimaging to compensate for individual variability. However, surface-based registration (SBR) techniques have an inherent advantage over VBR because they respect the topology of the convoluted cortical sheet. There is evidence that existing SBR methods indeed confer a registration advantage over affine VBR. Landmark-SBR ...

Progenitor cells undergo a series of stable identity transitions on their way to becoming fully differentiated cells with unique identities. Each cellular transition requires that new sets of genes are expressed, while alternative genetic programs are concurrently repressed. Here, we investigated how the proneural gene Neurog2 simultaneously activates and represses alternative gene expression p...
