The scattering of 38 MeV α-particles by C, N, 0, F and Kr nuclei
This paper describes observations by a photographic method on the angular distributions of 38 MeV α-particles scattered by light nuclei. Elastically and inelastically scattered particles were distinguished by their range in nuclear emulsion. The observed distributions are compared with the general predictions of the nuclear optical model, of direct interaction theories,and of the inelastic diffraction theory of Blair. In teraction radii are deduced from the angular distributions.
Embryo morphokinetics analysis and reproductive outcomes with assisted oocyte activation by a calcium ionophore after prior fertilization failure. A multicentric retrospective study
Abstract Background Fertilization failure or low fertilization rate after ICSI is around 1–3% in IVF treatments. Several strategies have been studied in order to bypass the lack of activation. The aim of this study is to evaluate embryo morphokinetics and reproductive outcomes after intracytoplasmic sperm injection (ICSI) with assisted oocyte activation (AOA) using a calcium ionophore (CaI) in patients with previous fertilization failure or low fertilization rate (under 30%) and severe male factor. Methods Multicentric retrospective cohort study including 70 patients with fertilization failure or low fertilization rate and severe male factor (sperm concentration under 1 million/mL) who unde…
The scattering of 28.5 MeV 3 He particles by 12 C, 20 Ne and 40 A nuclei
Differential cross-sections for the elastic and inelastic scattering of 28.5 MeV 3 He particles by the nuclei 12 C, 20 Ne and 40 A have been measured by means of a photographic technique. The 12 C ( 3 He, α) reaction was also observed. The elastic scattering distributions have been analyzed in terms of an optical model.
Study of nucleation status in the second cell cycle of human embryo and its impact on implantation rate
Objective To study nucleation status in two- and four-cell embryos and its effect on reproductive outcomes. Design Retrospective cohort study. Setting University-affiliated private center. Patient(s) A total of 1,679 embryos from 940 oocyte donation cycles from May 2012 to May 2014. Intervention(s) None. Main Outcome Measure(s) Implantation, morphokinetics, and nucleation status restoration. Result(s) Multinucleation was present in 42.53% of embryos with known implantation data at the two-cell stage; it was present in approximately 14% of them at the four-cell stage. In all, 73.4% of the embryos were multinucleated at two cells and restored their nucleation status when they cleaved into fou…
The human first cell cycle: impact on implantation.
The morphology of fertilization events has been related to successful implantation by subjective criteria (pronuclei score, pronuclei symmetry and position). This work first described these events by time-lapse technology and then compared the timings of fertilization events (second polar body extrusion, first and second pronuclei appearance, abuttal and fading) in implanted versus nonimplanted embryos in a 2-year cohort retrospective study. A total of 1448 transferred embryos from 842 patients undergoing intracytoplasmic sperm injection with oocyte donation were monitored, 212 embryos from treatments where the number of gestational sacs matched the number of transferred embryos and 687 emb…
