We present ab initio density functional theory calculations of the magnetic structure of perfectly cuboctahedral nanoparticles consisting of 147 iron atoms. The results are compared to geometrically relaxed cuboctahedral and icosahedral Fe147-clusters. It is found, that structural relaxation leads to a compression, which reduces especially the moments of the central atoms of the cluster, while ...

Flexibility and choice -The DAB signal is essentially a highly flexible over-air 'data-pipe' that can broadcast a wide range of service types, from purely audio-based to multimedia. Typically, each multiplex can broadcast five or more high-quality audio services plus a number of extra services. The multiplex can be dynamically reconfigured to introduce additional services, temporary or permanen...

Sekwencja DNA nie jest jedyną i decydującą determinantą składu aminokwasowego białka. Przed procesem translacji część transkrybowanego RNA podlega procesowi edycji zmieniającej jego sekwencję, czego wynikiem jest synteza innych białek, niż kodowane przez geny. Redagowanie dotyczy konwersji adeniny do inozyny, który to proces występuje w różnych tkankach i dotyczy wielu mRNA. Konwersję adenozyny...

Us3 is a serine/threonine protein kinase encoded by herpes simplex virus 1 (HSV-1). We recently identified serine at Us3 position 147 (Ser-147) as a physiological phosphorylation site of Us3 (A. Kato, M. Tanaka, M. Yamamoto, R. Asai, T. Sata, Y. Nishiyama, and Y. Kawaguchi, J. Virol. 82:6172-6189, 2008). In the present study, we investigated the effects of phosphorylation of Us3 Ser-147 on regu...

BACKGROUND The epithelial-mesenchymal transition (EMT) is a key developmental program that is often activated during cancer progression and may promote resistance to therapy. An analysis of patients (n = 71) profiled with both gene expression and a global microRNA assessment (∼ 415 miRs) identified miR-147 as highly anti-correlated with an EMT gene expression signature score and postulated to r...
