No full text«Reverendo signore mio». Note sulla lingua di Ramusio dalla corrispondenza con Pietro Bembo
No full textThe essay investigates G.B. Ramusio’s language in his letters to Pietro Bembo (1537-38)
preserved in the Ms. Ambrosianus D 335 inf. and recently published by A. Del Ben. This corpus is the
largest known amount of autograph texts written by the Venetian and gives a rare insight into
the tangled web of correspondents and into the fast communication links that lead to Venice from
various sources. Compared to Ramusio’s dissertations and introductions to the exploration accounts
published in the first volume of his Navigationi et viaggi (editio princeps 1550), these texts are quite
more colloquial: the linguistic analysis shows all the features of a lower register and lets many local
words and phrasemes appear to the surface of the page
THE DEVELOPMENT OF ABNORMAL HEART-RATE PATTERNS AFTER ABSENT END-DIASTOLIC VELOCITY IN UMBILICAL ARTERY - ANALYSIS OF RISK-FACTORS
No full textVentricular ejection force in growth-retarded fetuses
No full textThe objective of this study was to determine whether in growth-retarded fetuses secondary to uteroplacental insufficiency the cardiac ventricles exert a force different from that of appropriately grown fetuses. Doppler echocardiographic studies were performed in 156 appropriately grown fetuses (gestational age 18-38 weeks) and in 72 growth-retarded fetuses (gestational age 24-36 weeks) free from structural and chromosomal abnormalities and characterized by Doppler changes in the umbilical artery and middle cerebral artery suggesting uteroplacental insufficiency as the most likely etiology of the growth defect. Right and left ventricular ejection force values were calculated from velocity waveforms recorded at the level of aortic and pulmonary valves, according to Newton's second law of motion. In appropriately grown fetuses, left and right ventricular ejection force values significantly increased with advancing gestation and the two ventricles exerted similar force. In growth-retarded fetuses, the ventricular ejection force was significantly and symmetrically decreased in both ventricles. Among growth-retarded fetuses, a poorer perinatal outcome was observed in those fetuses in which the ejection force of both ventricles was below the 5th centile of the normal limits for gestation. In 12 growth-retarded fetuses followed longitudinally during the last week preceding intrauterine death or Cesarean section due to antepartum heart-rate late decelerations, a significant decrease of ejection force was found in both ventricles. Finally, a significant relationship was found between the severity of acidosis and right and left ventricular ejection force values in 22 fetuses in which Doppler recordings were performed immediately before cordocentesis.(ABSTRACT TRUNCATED AT 250 WORDS
