Assortative mating in phenotype in human marriages has been widely observed. Using genome-wide genotype data from the Framingham Heart study (FHS; number of married couples = 989) and Health Retirement Survey (HRS; number of married couples = 3,474), this study investigates genomic assortative mating in human marriages. Two types of genomic marital correlations are calculated. The first is a co...

Point mutations of the p53 tumor suppressor gene are a frequent finding in human carcinomas and are thought to be an important oncogenic event. In non-Hodgkin lymphomas, p53 mutations occur in a minor fraction of cases. However, conclusive data are still lacking for Hodgkin's disease (HD) where the analysis meets technical problems. The neoplastic tumor cell clone in HD is represented by the la...

El Perú posee el triste privilegio de ser el único país sudamericano considerado en este...

Large-scale data collection has become the kernel of the growth of knowledge in the social sciences. Nowhere is this more evident than in research in the demography of aging and the life course, where scientific progress has been stimulated and sustained by complementary longitudinal studies of aging populations. In this chapter, we review the history, organization, and design of two of these p...
