Yb(3+)-sensitized, Ln(3+)(Er(3+), Pr(3+))-doped Y6O5F8 micron-sized bundles of highly crystalline individual nanotubes have been prepared through hydrothermal syntheses at 185 °C. The inhomogeneous broadening observed in their optical spectra is associated with the large distribution of crystal fields around Y(3+)(Ln(3+)) sites in the orthorhombic Pbcm Vernier-type Y6O5F8 host. Based on ratiome...

Proteinase 3 (PR-3) is a human polymorphonuclear leukocyte (PMNL) serine proteinase that degrades elastin in vitro and causes emphysema when administered by tracheal insufflation to hamsters (Kao, R. C., Wehner, N. G., Skubitz, K. M., Gray, B. H., and Hoidal, J. R. (1988) J. Clin. Invest. 82, 1963-1973). We have determined the primary structure of several PR-3 peptides and have analyzed catalyt...

We have investigated the contributions of CuO planes and CuO chains on the transport properties of YBa Cu O by 2 2 4 8 Ž .

1 Progesterone receptors (PR) are critical mediators of mammary gland development and 2 contribute to breast cancer progression. Progestin-induced rapid activation of 3 cytoplasmic protein kinases leads to selective regulation of growth-promoting genes by 4 phospho-PR species. Herein, we show that phosphorylation of PR Ser81 is ck25 dependent and progestin-regulated in intact cells, but also oc...

We introduce a new kind of language model, which models whole sentences or utterances directly using the Maximum Entropy paradigm. The new model is conceptually simpler, and more naturally suited to modeling whole-sentence phenomena, than the conditional ME models proposed to date. By avoiding the chain rule, the model treats each sentence or utterance as a \bag of features", where features are...

This report describes the thermochemistry, proton-coupled electron transfer (PCET) reactions and self-exchange rate constants for a set of bis-benzimidazolate-ligated [2Fe-2S] clusters. These clusters serve as a model for the chemistry of biological Rieske and mitoNEET clusters. PCET from [Fe2S2((Pr)bbim)((Pr)bbimH)](2-) (4) and [Fe2S2((Pr)bbim)((Pr)bbimH2)](1-) (5) to TEMPO occurs via concerte...

PR-Set7/SET8 is a histone H4-lysine 20 methyltransferase required for normal cell proliferation. However, the exact functions of this enzyme remain to be determined. In this study, we show that human PR-Set7 functions during S phase to regulate cellular proliferation. PR-Set7 associates with replication foci and maintains the bulk of H4-K20 mono- and trimethylation. Consistent with a function i...
