Rationale: Cardiac progenitor cells (CPCs) in the adult heart are used for cell-based treatment of myocardial damage, but factors determining stemness, self-renewal, and lineage commitment are poorly understood. Immortal DNA strands inherited through asymmetric chromatid segregation correlate with self-renewal of adult stem cells, but the capacity of CPCs for asymmetric segregation to retain im...

We used cross-sectional data on 2,660 black and 2,611 Mexican-American adult participants in the National Health and Nutrition Examination Survey (1999-2006) to investigate the association between metropolitan-level racial/ethnic residential segregation and obesity and to determine whether it was mediated by the neighborhood socioeconomic environment. Residential segregation was measured using ...

BACKGROUND There is a great amount of literature concerning the effect of racial segregation on health outcomes but few papers have discussed the effect of segregation on the basis of social, demographic and economic characteristics on health. We estimated the independent effect of segregation of determinants of socioeconomic status on infant mortality in Iranian population. METHODS For measu...

Several recent studies have concluded that residential segregation by income in the U.S. has increased in the decades since 1970, including a significant increase after 2000. Income segregation measures, however, are biased upwards when based on sample data. This is a potential concern because the sampling rate of the American Community Survey (ACS)—from which post-2000 income segregation estim...

In the present work, we used Cu-Sb alloy system as a model to study grain boundary segregation in specimens prepared by rapid quenching. Ribbons of Cu-Sb alloys of single Cu phase and polycrystalline structure containing 0.01, 0.08, and 2wt% Sb prepared by single roller melt spinning were used as specimens, and the segregation was studied by using energy dispersive X-ray spectrometer attached t...
