Abstract The EUROMACS Right-Sided Heart Failure Risk Score was developed to predict right ventricular failure (RVF) after left assist device (LVAD) placement. predictive ability of the score has not been tested in other cohorts. We performed a single center analysis continuous-flow (CF) LVAD cohort (n = 254) where we calculated risk scores and assessed for heart implantation. Thirty-nine percen...

Laser resonance ionization spectroscopy was performed on the rare einsteinium isotopes $^{253\ensuremath{-}255}\mathrm{Es}$ at RISIKO mass separator in Mainz. With low sample sizes ranging down to femtograms, prominent 352 nm-ground-state transition measured all three isotopes, and four additional ground-state transitions were $^{254}\mathrm{Es}$. Hyperfine-structure analysis resulted assigned ...

BACKGROUND Mutations in the BRCA1 and BRCA2 genes are found in most families with cases of both breast and ovarian cancer or with many cases of early-onset breast cancer. However, in an outbred population, the prevalence of BRCA1 and BRCA2 mutations in patients with breast cancer who were unselected for a family history of this disease has not been determined. METHODS Mutations in the BRCA1 a...
