Spin polarized semimagnetic exciton-polariton condensate in magnetic field.

Owing to their integer spin, exciton-polaritons in microcavities can be used for observation of non-equilibrium Bose-Einstein condensation in solid state. However, spin-related phenomena of such condensates are difficult to explore due to the relatively small Zeeman effect of standard semiconductor microcavity systems and the strong tendency to sustain an equal population of two spin components, which precludes the observation of condensates with a well defined spin projection along the axis of the system. The enhancement of the Zeeman splitting can be achieved by introducing magnetic ions to the quantum wells, and consequently forming semimagnetic polaritons.

[Profile of estrogen receptor alpha isoforms in endometrial adenocarcinoma].

Affectivity of activity of wild-type estrogen receptors forms depends not only from transcriptional activity of their encoding genes, but also from participation of ERs isoforms in entire ERs mRNA pool. Estrogen receptor mRNA isoforms are essential intracellular factor regulating cellular answer of estrogen. ERs expression, as well as the mRNA splice variants, may influence the biological properties of some tumors and affect their ability to respond to estrogen and antiestrogen therapies.
