Multinucleon transfer reactions and proton transfer channels

Transfer reactions have always been of great importance for nuclear structure and reaction mechanism studies. So far, in multinucleon transfer studies, proton pickup channels have been completely identified in atomic and mass numbers at energies close to the Coulomb barrier only in few cases. We measured the multinucleon transfer reactions in the 40Ar+208Pb system near the Coulomb barrier, by employing the PRISMA magnetic spectrometer. By using the most neutron-rich stable 40Ar beam we could populate, besidesneutron pickup and proton stripping channels, also neutron stripping and proton pickup channels. Comparison ofcross sections between different systems with the 208Pb target and with projectiles going from neutron-poor to neutron-rich nuclei, as well as between the data and GRAZING calculations, was carried out.Finally, recent results concerning the measurement of the excitation function from the Coulomb barrier to far below for the 92Mo+54Fe system, where both proton stripping and pickup channels were populated with similar strength, will be discussed

Neonatal intrapericardial teratoma: a challenge for the pediatric surgeon

Abstract Congenital intrapericardial teratoma can present in the fetal and neonatal period, but prenatal diagnosis is difficult. Its clinical course, similar to that of an anterior mediastinal mass, may be fatal if the tumor is not promptly excised. We report the case of a fetus with a large anterior mediastinal mass associated with hydramnios, pleural effusion, and ascites. Perinatal surgical removal is the only lifesaving therapy; any conservative approach in these neonates should be avoided even if critically symptomatic
