Updated Next-to-Next-to-Leading-Order QCD Predictions for the Weak Radiative B-Meson Decays.

Weak radiative decays of the B mesons belong to the most important flavor changing processes that provide constraints on physics at the TeV scale. In the derivation of such constraints, accurate standard model predictions for the inclusive branching ratios play a crucial role. In the current Letter we present an update of these predictions, incorporating all our results for the O(α_{s}^{2}) and lower-order perturbative corrections that have been calculated after 2006. New estimates of nonperturbative effects are taken into account, too. For the CP- and isospin-averaged branching ratios, we find B_{sγ}=(3.36±0.23)×10^{-4} and B_{dγ}=(1.73_{-0.22}^{+0.12})×10^{-5}, for E_{γ}>1.6 GeV. Both results remain in agreement with the current experimental averages. Normalizing their sum to the inclusive semileptonic branching ratio, we obtain R_{γ}≡(B_{sγ}+B_{dγ})/B_{cℓν}=(3.31±0.22)×10^{-3}. A new bound from B_{sγ} on the charged Higgs boson mass in the two-Higgs-doublet-model II reads M_{H^{±}}>480 GeV at 95% C.L.

Estimate of B(B(over) -->Xgamma) at O(alpha(s)2).

Combining our results for various O(alpha[s]) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next-to-leading order in QCD. We find B(B[over ]-->X[s]gamma)=(3.15+/-0.23) x 10(-4) for Egamma>1.6 GeV in the B[over ]-meson rest frame. The four types of uncertainties:nonperturbative (5%), parametric (3%), higher-order (3%), and m(c)-interpolation ambiguity (3%) have been added in quadrature to obtain the total error.

[Behavior of blood ferritin in acute myocardial infarct]. / Comportamento della ferritinemia nell'infarto miocardico acuto.

Ferritin (F) is an iron-protein (molecular weight 445.000) present in various organs including the heart. Using the immunoenzymatic method (Ferrizyme Abbott), ferritinemia (Fe) was determined daily in 28 patients with acute myocardial infarction (AMI). A significant rise was revealed, already evident in the first few days 8-9 after with Fe gradually returns to baseline levels. The results have shown that this pattern is not evident in patients with angina, heart failure, valve defects, pericarditis or cor pulmonale and may thus be considered a reliable, if not early, marker of myocardial cytolysis. In those cases studied no correlations were observed between CPK and Fe peak or between these and clinical intensity of AMI.

When the hospice patient is manipulative.

Oncology and hospice literature have addressed the problem of psychiatric complications, secondary to the stressors of diagnosis and treatment. This literature focuses particularly on depression and anxiety, which not only compound patients' suffering but also may interfere with optimal care. Little attention has been given, however, to the unique challenges of providing hospice care to patients with preexisting psychiatric conditions. As hospice care becomes increasingly mainstream in the health care system, we can expect to meet more patients with such conditions. In order to contribute to collegial dialogue that addresses this minority population in hospice services, a case study is presented in this article of the process of care for a hospice patient with a preexisting psychiatric condition. Interventions are suggested, using a theoretical matrix of hospice philosophy and principles of care for manipulative patients.
