The appearance on single leukemic blast cells of markers of at least two different lineages has been termed lineage infidelity. MOLT-3 cells, a continuous line of human T lymphoblasts, express T cell markers as defined immunologically with monoclonal antibodies. Following a single exposure to 5-azacytidine, other markers, usually associated with non-T cell lineages, appeared transiently. A stab...

Intimate emotional and sexual relationships outside of marriage or a committed relationship occur with high frequency in both community and, particularly, clinical populations. Clinicians are likely to confront infidelity not only among couples they treat, but also among individuals struggling with their own or their partner’s affair and among children contending with consequences of a parent’s...

Evolutionary theory based research shows that attractiveness is based on biological correlates that index appropriate estrogen and testosterone levels. Symmetry affects or plays a role in the perception of many of these correlates of attractiveness. Additionally, since attractiveness affects infidelity perception and reactions, sexual satisfaction, and personality perception, symmetry also affe...

According to the theory of evolved sex differences in jealousy, the challenge for women to ensure paternal investment increased their jealousy response to emotional infidelity, whereas paternal uncertainty exerted selective pressures that shaped men to become more distressed by sexual infidelity.

Recent research examining sex differences in jealousy suggests that more men than women tend to be distressed by sexual infidelity, and that more women than men tend to be distressed by emotional infidelity. The primary explanation for these findings is that evolution has shaped men’s and women’s responses to enhance their chances of reproductive success. However, within-sex differences are als...

Temptation pervades modern social life, including the temptation to engage in infidelity. The present investigation examines one factor that may put individuals at a greater risk of being unfaithful to their partner: dispositional avoidant attachment style. The authors hypothesize that avoidantly attached people may be less resistant to temptations for infidelity due to lower levels of commitme...

Studies examining sex differences in jealousy have often relied on student samples and were restricted to the evaluation of a selected few moderators. In this study, a nationally representative survey of American households was presented with either an actual or a hypothetical infidelity scenario (which appeared as either a forced choice or as continuous measures). Significant sex differences o...

Although most epidemic human infectious diseases are caused by recently introduced pathogens, cospeciation of parasite and host is commonplace for endemic infections. Occasional host infidelity, however, provides the endemic parasite with an opportunity to survive the potential extinction of its host. Such infidelity may account for the survival of certain types of human lice, and it is current...
