BES II data for J/Ψ → K * (890)Kπ reveal a strong κ peak in the Kπ S-wave near threshold. Both magnitude and phase are determined in slices of Kπ mass by interferences with strong K 0 (1430), K 1 (1270) and K 1 (1400) signals. The phase variation with mass agrees within errors with LASS data for Kπ elastic scattering. A combined fit is presented to both BES and LASS data. The fit uses a Breit-W...
The physiological basis of training responses in women, and particularly older women, is not well understood. Short-term aerobic training (STAT) was used to probe the effects of age and hormone-replacement therapy (HRT) on women's ability to rapidly change peak uptake ( VO(2max)), plasma volume and cardiac function. A total of 39 females participated in the STAT programme: 15 younger (Y; aged 1...
We evaluated the susceptibility to Ebola and Marburg virus infection of mice that cannot respond to interferon (IFN)-α/β and IFN-γ because of deletion of the STAT-1 gene. A mouse-adapted Zaire ebolavirus (ZEBOV) caused rapidly lethal disease; wild-type ZEBOV and Sudan Ebolavirus and 4 different Marburg virus strains produced severe, but more slowly progressive illness; and Reston Ebolavirus cau...
We measure the masses of b hadrons in exclusively reconstructed final states containing a J/psi --> mu-mu+ decay using 220 pb(-1) of data collected by the CDF II experiment. We find: m(B+) = 5279.10 +/- 0.41(stat.) +/- 0.36(sys.) MeV/c2, m(B0) = 5279.63 +/- 0.53(stat.) +/- 0.33(sys.) MeV/c2, m(B(s)0) = 5366.01 +/- 0.73(stat.) +/- 0.33(sys.) MeV/c2, m(lambda(b)0) = 5619.7 +/- 1.2(stat.) +/- 1.2(...
Acute lung injury associated with surfactant deficiency remains a major cause of pulmonary morbidity and mortality. Since signal transducer and activator of transcription-3 (STAT-3) plays an important role in protecting respiratory epithelial cells during injury, we hypothesized that STAT-3 may regulate gene expression in type II cells that mediate surfactant phospholipid synthesis. Conditional...
The JAK/STAT pathway is altered in T-cell large granular lymphocytic leukemia. In all patients, leukemic LGLs display upregulation of phosphorylated STAT3 (P-STAT3) that activates expression of many antiapoptotic genes. To investigate the mechanisms maintaining STAT3 aberrantly phosphorylated using transcriptional protein and functional assays, we analyzed interleukin (IL)-6 and suppressor of c...
Appendix A Deriving Equations for M+ME Biases and for t-statistic Overestimations Determining the Impact of VIF Bias on the t-statistic Consider first the situation where we have no measurement error. Using standard equations for the estimated standard error of β2 from any regression textbook, an unbiased and consistent estimate of the standard error is s = Σεi / (N – K) (A1-1) and the estimate...
Platinum-based chemotherapeutics are amongst the most powerful anti-cancer drugs. Although their exact mechanism of action is not well understood, it is thought to be mediated through covalent DNA binding. We investigated the effect of platinum-based chemotherapeutics on signaling through signal transducer and activator of transcription (STAT) proteins, which are involved in many oncogenic sign...
Cytokines and growth factors induce activation of the family of signal transducers and activators of transcription (Stats) that directly activate gene expression. Recently, constitutively activated Stat1, Stat3, and Stat5 were identified in nuclear extracts of acute myeloid leukemia (AML) patients, suggesting involvement of constitutive Stat activity in the events of leukemogenesis. In the pres...
