The energy balance between heat excess and 4 He in the gas phase has been found to be reasonably satisfied even if the low levels of 4 He do not give the necessary confidence to state definitely that we are dealing with the fusion of deuterons to give 4 He. In the melted cathode, the data of which are reported, no 4 He was found at the achieved sensitivity.(More)
Physiologic concentration in amniotic fluid (AF) of several metabolites has not been established with certainty. In this study, we initially assayed purines, pyrimidines, and amino compounds in 1,257 AF withdrawn between the 15th and the 20th week of gestation from actually normal pregnancies (normal gestations, normal offspring). Results allowed to(More)
Endometriosis is defined as the presence of endometrial mucosa (glands and stroma) abnormally implanted in locations other than the uterine cavity. Deep infiltrating endometriosis (DIE) is considered the most aggressive presentation of the disease, penetrating more than 5 mm in affected tissues, and it is reported in approximately 20% of all women with(More)
OBJECTIVE To evaluate the accuracy of ultrasound in visualizing placental cord insertion (PCI) at different gestational ages in order to recommend the most feasible period during pregnancy to identify it. Secondary aim was to propose a predictive algorithm for PCI visualization. METHODS We performed a single-center, prospective cohort study. We enrolled(More)
OBJECTIVE To establish reference charts for fetal cerebellar vermis height in an unselected population. METHODS A prospective cross-sectional study between September 2009 and December 2014 was carried out at ALTAMEDICA Fetal-Maternal Medical Centre, Rome, Italy. Of 25203 fetal biometric measurements, 12167 (48%) measurements of the cerebellar vermis were(More)
A fetus with de novo ring chromosome 16 is presented. At 20 weeks' gestation, ultrasound examination demonstrated bilateral clubfoot, bilateral renal pyelectasis, hypoplasia of the corpus callosum, and transposition of the great vessel. Amniocentesis was performed. Chromosome analysis identified a ring chromosome 16 [47,XY,r(16)] and array comparative(More)
