F117Hystero-embryoscopic findings in early nonviable pregnancies
2000
Background A high proportion of early pregnancy losses are associated to abnormal embryo development. However, chromosomal analysis of routine curettage samples are of limited value; and histopathological examinations of the embryos are rarely performed in clinical practice. Method A transcervical hystero-embryoscopy was performed prior to the curettage in 31 nonviable first-trimester pregnancies and a control group of 5 early terminations of pregnancy. In the study group, the estimated gestational age according to the ultrasound findings was 6.7 (4–9) menstrual weeks. Direct biopsies of different gestational structures were taken during the endoscopic procedure. Results In nonviable pregna…
First β-decay spectroscopy of $^{135}$In and new $β$-decay branches of $^{134}$In
2021
International audience; The $\beta$ decay of the neutron-rich $^{134}$In and $^{135}$In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number $Z=50$ above the $N=82$ shell. The $\beta$-delayed $\gamma$-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. Three $\beta$-decay branches of $^{134}$In were established, two of which were observed for the first time. Population of neutron-unbound states decaying via $\gamma$ rays was identified in the two daughter nuclei of $^{134}$In, $^{134}$Sn and $^{133}$Sn, at…
