Recent statistical and computational analyses have shown that a genealogical most recent common ancestor (MRCA) may have lived in the recent past [Chang, J.T., 1999. Recent common ancestors of all present-day individuals. Adv. Appl. Probab. 31, 1002-1026. 1027-1038; Rohde, D.L.T., Olson, S., Chang, J.T., 2004. Modelling the recent common ancestry of all living humans. Nature 431, 562-566]. Howe...

The effects of endothelin-1 (ET-1) on mucosal mast cells are of special interest, since they may be an important component of the tissue response that occurs during ischaemic preconditioning or ischaemia/re-oxygenation injuries. Increasing doses of ET-1 were administered intravenously to anaesthetized rats. In a second series of experiments, animals were pretreated with the ET(A) receptor antag...

Abstract We report on the results of our simultaneous observations three large stellar flares with soft X-rays (SXRs) and an Hα emission line from two binary systems RS CVn type. The energies released in X-ray emissions during were 1036–1038 1035–1037 erg, respectively. This renders set as first successful X-ray/Hα above 1035 erg; although coverage was limited, $\sim\! 10\%$ e-folding time deca...

OBJECTIVE To compare the diagnostic performance of new and established full-field digital mammography (FFDM) systems. MATERIALS AND METHODS During a 15-month period, 1038 asymptomatic women who visited for mammography were prospectively included from two institutions. For women with routine two-view mammograms from established FFDM systems, bilateral mediolateral oblique (MLO) mammograms were...
